BACKGROUND OF THE INVENTION

The present invention is generally related to data distribution, and in particular to systems and methods for performing digital rights management in relation to data distribution.
The computer architecture with a central processor governing a local, centralized memory has been a standard in computing for decades. The architecture utilizes a central repository that is perceived as a slave to an associated processor. A myriad of devices utilizing the familiar processor and memory structure have been developed. For example, a number of consumer devices including audio recorders, audio players, cell phones, video players, video game devices, video recorders and the like have been developed that include a central memory local to the particular device and operating as a slave to a governing processor within the device. Such devices have proliferated in the market and have satisfied a continuing consumer demand.
The growth of digital rights management has exposed various limitations of a data repository governed by a local processor. In particular, digital content providers are willing to sell content to consumers and allow the consumers to maintain and use the content for as long as the consumer desires. This promise, however, has proven to be somewhat illusory due to the incompatibility of content rights and other issues. Because of these incompatibilities, digital rights management often limits the use of purchased content to a device on which the content was originally deployed. Thus, for example, a consumer may purchase a particular ring tone from a content provider and download the purchased ring tone to a cell phone. The consumer may then use the ring tone as long as the consumer continues to use the cell phone. Once the cell phone is replaced, the consumer is forced to re-purchase the ring tone. Alternatively, the consumer is forced to download the purchased ring tone from a service supporting the digital rights management scheme used in relation to the ring tone. Each time the user accesses such a service, they are charged. Thus, from a consumer's perspective, such services are not fundamentally different from simply repurchasing the content at issue for use on the new device.
Hence, for at least the aforementioned reasons, there exists a need in the art for advanced systems and methods for allowing appropriate use of digital information while at the same time assuring the security of the information.

BRIEF SUMMARY OF THE INVENTION

The present invention is generally related to data distribution, and in particular to systems and methods for performing digital rights management in relation to data distribution.
Various embodiments of the present invention provide systems for distributing rights managed content objects. Such systems include a mobile application device and a mobile storage device. The mobile storage device includes a processor, a wireless interface, and a storage component including a non-volatile memory component. The mobile storage device is communicably coupled to the mobile application device via the wireless interface, and a graphical user interface of the mobile application device is used to control access to the mobile storage device. The storage component includes at least one content object and instructions executable by the processor to provide an information set to the mobile application device via the wireless interface. The information set is used to drive the graphical user interface of the mobile application device, whereby the graphical user interface operates as a remote graphical user interface for the mobile storage device. The instructions are further executable by the processor to receive the content object and to store the content object in a native format. The instructions are further executable by the processor to: receive a request for the content object that indicates a selected format, access the content object from the storage component, access a digital rights management tool associated with the content object, decrypt the content object using the digital rights management tool, convert the format of the decrypted content object from the native format to the selected format, and stream the decrypted and format converted content object via the wireless interface to the mobile application device.
Other embodiments of the present invention provide methods for distributing rights managed content objects. Such methods include providing a mobile storage device that includes a wireless interface and a storage component maintaining a rights managed content object. A first request to provide the rights managed content object to a first mobile application device via the wireless interface is received, and a second request to provide the rights managed content object to a second mobile application device via the wireless interface is received. The rights managed content object is accessed from the storage component, and a digital rights management tool associated with the accessed content object is accessed. The rights managed content object is decrypted using the digital rights management tool, and streamed to both the first mobile application device and the second mobile application device via the wireless interface.
In some instances of the aforementioned embodiments, the methods further include receiving the rights managed content object, and storing the rights managed content object to the storage component in a native format. In some cases, the first request and the second request indicate different formats in which the rights managed content object is to be delivered. In such cases, a format conversion of the rights managed content object from the native format to a selected format may be performed before delivering the rights managed content object to the recipient.
In some instances of the aforementioned embodiments, the digital rights management tool is a decryption key, while in other instances of the aforementioned embodiments, the digital rights management tool includes a set of instructions executable by the processor to decrypt the accessed content object. Based on the disclosure provided herein, one of ordinary skill in the art will recognize a variety of digital rights management tools that may be used in relation to one or more embodiments of the present invention. In some cases, the storage component includes both a hard disk drive and a flash memory, while in other cases, the storage component includes one or the other of a hard disk drive and a flash memory. The wireless interface may be, but is not limited to, a Bluetooth interface and/or a WiFi interface.
Yet other embodiments of the present invention provide systems for distributing rights managed content objects. Such systems include a mobile storage device with a processor, a wireless interface, and a storage component. The storage component maintains at least a first content object and a second content object. In addition, the storage component includes instructions executable by the processor to access one of the first content object or the second content object from the storage component, and to access a digital rights management tool associated with the accessed content object. The instructions are further executable to decrypt the accessed content object using the digital rights management tool, and to distribute the decrypted content object via the wireless interface to a mobile application device. In some instances of the aforementioned embodiments, the systems further include a graphical user interface that is incorporated into the mobile application device. The graphical user interface operates as a remote graphical user interface for the mobile storage device.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is generally related to data distribution, and in particular to systems and methods for performing digital rights management in relation to data distribution.
Some embodiments of the present invention utilize a mobile storage device such as a Universal Mobile Content Storage (UMCS) device that is, among other things, capable of storing one or more content objects and performing desired digital rights management in relation to the stored content objects. As used herein, the phrases “rights managed” and “digital rights management” are used in their broadest sense to mean any of several technologies or approaches known in the art and developing in the art that may be used to limit access to the information to those who have been provided with a key to decrypt or decode the information. Thus, for example, a rights managed content object is any data that is encrypted or wrapped in such a way that its use and distribution is intended to be limited to those having a digital rights management tool capable of decrypting or otherwise unwrapping the rights managed content object. It should be noted that as used herein, rights managed content objects may be, but arc not limited to, consumer content objects such as, for example, audio, video and/or software objects; and enterprise content such as, for example, documents and the like. Also, as used herein, the phrase “content object” is used in its broadest sense to mean any set of information that can be used by an application device. Thus, for example, a content object may be a digital audio file, a digital video file, a computer software program, a document, or the like. In some cases, a variety of digital rights management schemes are supported such that the mobile storage device may support storage and distribution of content objects using different approaches to digital rights management. In such embodiments, digital rights managed content may be carried with a user, and thus is local to devices in use by the user. Further, the content may be accessed and utilized using one or more devices that are capable of connecting to the mobile storage device using either a wired or wireless connection.
In operation, a content object may be requested by a device communicably coupled to the mobile storage device. Upon receiving the request, the mobile storage device determines if a digital rights management scheme is employed, and if so, which one. The appropriate digital rights management module is then selected to unwrap the selected content object(s). Once unwrapped, the content object(s) are then streamed to the requesting device in a way that provides some level of assurance that the content object(s) is/are protected from illicit copying.
Turning to FIG. 1, a diagram depicts an exemplary content usage network 100 that may be utilized in accordance with various embodiments of the present invention. Content usage network 100 may be utilized to distribute one or more rights managed content objects from a UMCS device to one or more recipient devices. Exemplary content usage network 100 includes a UMCS 110 at the core thereof. UMCS 110 is able to receive content objects from one or more online and wireless content providers as well as from various self maintained application devices such as, for example, audio recorders and video recorders. In some cases, UMCS 110 may be intermittently wired to a personal computer 115 via a cable 117. In such cases, UMCS 110 may be configured via personal computer 115 using the standard I/O interfaces associated with personal computer 115.
Wireless network 120 may be any wireless network known in the art. Thus, for example, wireless network 120 may be, but is not limited to, a Bluetooth™ network or WiFi network as are known in the art. As indicated above, the word “Bluetooth” is a trademark of Bluetooth SIG, Inc. For clarity, later use of the word Bluetooth is done without the customary trademark designation. It should be noted that while UMCS 110 may be configured across wireless network 120 using the user interface of another application device, and it may also be configured using other approaches. Thus, for example, UMCS 110 may be self configuring. In such a case, UMCS 110 is implemented with enough intelligence to auto detect an available wireless network as well as devices attached via the wireless network. As a particular example, UMCS 110 may be implemented such that when power is applied to the device it automatically scans for Bluetooth devices that are within range of UMCS 110. Based on the detected Bluetooth devices, UMCS 110 may form a service offering as is more fully discussed below.
UMCS 110 is capable of interacting with various devices and classes of devices via wireless network 120. For example, in some cases, UMCS 110 is operable to interact directly with UMCS enabled application devices via wireless network 120. Such UMCS enabled application devices include capability to authenticate to UMCS 110 and to accept and transfer information from/to UMCS 110, and to provide digital rights management whereby content is secured not only in the transfer between UMCS 110 and the UMCS enabled application device, but is also maintained secure within the UMCS enabled application device. In the situation where wireless network 120 is a Bluetooth network, the aforementioned UMCS enabled application devices would include Bluetooth capability. Alternatively, or in addition, in the situation where wireless network 120 is a WiFi network, the aforementioned UMCS enabled applications devices would include WiFi capability.
In various cases, UMCS 110 is operable to interact directly with non-UMCS enabled application devices via wireless network 120. In such cases, either UMCS 110 includes capability to tailor output and receive input from the non-UMCS enabled application device, or the non-UMCS enabled application devices may interact with UMCS 110 via a specialized UMCS converter that is tailored for operation with a class of devices. Thus, for example, where wireless network 120 is a Bluetooth network, the UMCS converter may be enabled to receive from and provided information to a non-UMCS enabled application device via any one of a number of communication approaches, and to communicate the information to/from UMCS 110 using a Bluetooth protocol. As an example, UMCS 110 may interact with digital audio devices (e.g., a digital audio player 151 and a digital audio recorder 152) via a UMCS digital audio converter 150. As another example, a cellular telephone 161 or personal digital assistant (not shown) may interact with UMCS 110 either directly or via a UMCS audio/video converter 160. As yet another example, UMCS 110 may interact with video devices (e.g., a set top box 166, a video cassette player 167, a digital video recorder 168 and a television 169) via a UMCS digital video converter 165. As yet a further example, UMCS 110 may interact with still image devices such as a digital still camera 171 or a printer (not shown) via a UMCS digital image converter 170. As yet another example, UMCS 110 may interact with a GPS receiver/display 176 via a UMCS GPS converter 175.
In various cases, UMCS 110 is operable to interact directly with non-UMCS enabled application devices via a UMCS composite converter 140. UMCS composite converter 140 is operable to provide for UMCS interaction with multiple classes of recipient devices. Thus, for example, where wireless network 120 is a Bluetooth network, UMCS composite converter 140 may be enabled to receive from and provided information to different classes of non-UMCS enabled application devices via any one of a number of communication approaches, and to communicate the information to/from UMCS 110 using a Bluetooth protocol. As an example, UMCS composite converter 140 may couple UMCS 110 to, for example, a digital audio player 141, a digital video recorder 142, a television 143, a set top box 144, a digital still camera 145, a video cassette player 146, a digital audio recorder 147, a cellular telephone 148, and a GPS receiver 149, or some combination of the aforementioned device classes. In such cases, decoding of content accessed from a storage medium included in UMCS 110 is done using a decoder provided in UMCS composite converter 140. Thus, the content is unwrapped by UMCS 110 and the unwrapped content is provided to the UMCS composite converter 140 via wireless network 120. UMCS composite converter 140 decodes the content and provides it to the appropriate recipient device while at the same time assuring that any demanded digital rights management is maintained. In some cases, UMCS composite converter 140 may be implemented as a dongle associated with one or more recipient devices.
Further discussion of content usage networks including UMCS devices is provided in the patent application entitled “Systems and Methods for Mobile Data Storage and Acquisition” that was previously incorporated herein by reference for all purposes.
Turning to FIG. 2, a flow diagram 500 illustrates a method in accordance with one or more embodiments of the present invention for binding a UMCS device with other local devices in accordance with one or more embodiments of the present invention. Following flow diagram 500, a UMCS device is powered on or otherwise enabled (block 510). Once enabled, the UMCS device detects any available networks (block 520) and attempts to authenticate itself to such networks (block 530). The aforementioned detection and authentication may include awaiting authentication by a particular network, identifying whether the network is a known network, and/or the like. Thus, where the network is a Bluetooth network, the UMCS device transmits and/or receives signals in accordance with a Bluetooth network protocol. Alternatively, or in addition, where the network is a WiFi network, the UMCS device transmits and/or receives signals in accordance with a WiFi network protocol. Next, for each authenticated network, the UMCS device identifies other UMCS enabled or UMCS accessible devices communicably coupled to the network (block 540). This may be done using any method for identifying connected devices that are known in the art. For one or more of the detected devices, an authentication process is performed to bind a particular device to the UMCS (block 550). Such authentication processes may involve accessing a unique identifier associated with the device to be authenticated and checking the unique identifier with a list of know devices maintained on the UMCS. Alternatively, or in addition, a user name and password may be requested from the device to be authenticated and where the user name and password match, the device is authenticated. Based on the disclosure provided herein, one of ordinary skill in the art will appreciate other authentication approaches that may be used in relation to one or more embodiments of the present invention.
Once the various devices have been authenticated (block 550), they are bound to the UMCS by including the authenticated devices in a list of known devices and maintaining communication with the bound devices (block 560). Further, the detection/authentication processes (blocks 520-560) are periodically repeated or repeated upon command. Thus, it is periodically determined whether an update to the list of known of devices is to be performed (block 570). An update to the list of known devices may be called for whenever a previously unidentified device is detected via the network or whenever one of the devices on the known devices becomes unavailable. Where an update to the list of known devices is to be performed, the aforementioned steps are repeated resulting in an updated list of known devices (blocks 520-560).
Turning to FIG. 3, a UMCS 200 in accordance with one or more embodiments of the present invention is depicted. UMCS 200 includes a hard disk drive 205 that is accessible to a processor 210 via a hard disk drive interface 215. Hard disk drive interface 215 may be any interface known in the art that allows for transferring data to and from hard disk drive 205. Further, hard disk drive 205 may be any hard disk drive known in the art. In one particular case, hard disk drive interface 215 is a standard ATA interface and hard disk drive 205 is an ATA hard disk drive.
In addition, UMCS 200 includes multiple transmission paths 230 each coupled to processor 210 via a system bus 250. As depicted, UMCS 200 includes three distinct transmission paths each including a transmitter/ receiver 232, 234, 236 electrically coupled to a respective antenna 241, 242, 243 and a local buffering memory 231, 233, 235. It should be noted that UMCS 200 may include more or fewer transmission paths depending upon the intended use and/or design of UMCS 200.
UMCS 200 also includes a memory system comprising a flash memory 258 and a system memory 254 electrically coupled to processor 210 via system bus 210. Some embodiments of the present invention utilize the combination of hard disk drive 205 and flash memory 258 to limit the power consumption of UMCS 200. As considerable power is expended spinning up hard disk drive 205, larger less frequent accesses to hard disk drive offers considerable power savings for UMCS 200. Based in part on this, some embodiments of the present invention carefully tailor the size and allocation of flash memory 258 such that the access to hard disk drive 205 is limited. When such accesses to hard disk drive 205 are performed, large amounts of properly selected data are moved from hard disk drive 205 to flash memory 258. In contrast to other approaches where large contiguous blocks of data are pulled from a hard disk drive to a cache memory, the data pulled from hard disk drive 205 to flash memory 258 is not necessarily contiguous. Further, in some cases, the data copied from hard disk drive 205 to flash memory 258 is dictated by the particular memory type and/or a media assemblage of a number of content objects.
Further discussion of UMCS devices that may be utilized in relation to one or more embodiments of the present invention is provided in the patent application entitled “Systems and Methods for Mobile Data Storage and Acquisition” that was previously incorporated herein by reference for all purposes. It will be noted that one or more of the mobile storage devices disclosed in the aforementioned patent application do not include a graphical user interface, or include only a very limited graphical user interface. In such cases, the graphical user interface of a communicably coupled mobile application device may be used to control the mobile storage device. As previously suggested, such mobile application devices may include, but are not limited to, MP3 players, portable video players, personal digital assistants, and the like. Further, it should be noted that while three antennae are shown as part of UMCS 200, single antenna implementations that are able to support multiple wireless channels are possible in accordance with one or more embodiments of the present invention. One example of such a single antenna approach supporting multiple wireless channels is provided in the patent application entitled “Systems and Methods for Multiport Communication Distribution” that was previously incorporated herein by reference for all purposes.
Turning to FIG. 4, a block diagram of a digital rights management system 700 in accordance with one or more embodiments of the present invention is depicted. Digital rights management system 700 includes one or more content objects 710, a number of digital rights management modules 720, a number of format conversion modules 730 and a processor. Each content object 710 includes a content object payload 712 and a file descriptor 714. Content object payload 712 includes the data that either without modification or after decryption includes the content of content object 710. Thus, as just some of many examples, content object payload 712 may be a digitized music selection, a digitized video selection, a software program or the like. File descriptor 714 includes one or more fields of information describing content object 710. As shown, file descriptor 714 includes a field 716 that identifies the native format of content object payload 712 and a field 718 that identifies any digital rights management that is applied to content object payload 712. Based on the disclosure provided herein, one of ordinary skill in the art will recognize a variety of content objects, content object payloads and file descriptors that may be used in relation to one or more embodiments of the present invention. In one particular embodiment of the present invention, digital rights management system 700 is implemented as part of a UMCS device.
In operation, content object 710 is selected for distribution. The selection may be received from another device that is communicably coupled to digital rights management system 700, and may include an indication of a final format in which the selected content object is to be provided. Where no indication of a final format is received, it is assumed that delivery of the selected content object in its native format is acceptable. As used herein, the phrase “native format” is used in its broadest sense to mean any format in which a particular content object is maintained on a storage component that is accessible to processor 740. Thus, for example, where the selected content object is an audio file, the native format may be MP3 or high definition audio. Based on the disclosure provided herein, one of ordinary skill in the art will recognize a number of native formats in which a particular content object may be maintained.
In response to the selection of content object 710, processor 740 accesses content object 710 from a storage element accessible to processor 740. Processor 740 utilizes the information in file descriptor 714 to determine which, if any, digital rights management module 720 that will be used to decrypt or otherwise unwrap content object payload 712. The selected digital rights management module 720 is executed by processor 740 to decrypt or otherwise unwrap content object payload 712. Where a digital rights management approach is not identified in file descriptor 714, it is assumed that digital rights management is not implemented. In such a case, digital rights management module 720 is not selected, and the aforementioned decryption/unwrapping process is skipped.
Further, where the original selection of content object 710 indicates a final format that is different from the native format indicated by file descriptor 714, processor 740 selects an appropriate one of format conversion modules 730 to convert object payload 712 from the native format indicated by file descriptor 714 to the indicated file format. Once the aforementioned decryption and format conversion is complete, content object payload 712 is provided to an indicated recipient device as a streamed content object 750.
Providing streamed content object 750 may include, but is not limited to, transmitting decrypted and format converted portions of content object payload 712 piece-meal. Once the portions are received by a receiving device the content object payload is decoded and consumed in an audio, visual or other fashion appropriate to the particular content object. Once consumed, the portions of content object payload 712 are deleted from the recipient device in accordance with digital rights management associated with the content object. In some cases, the information is provided via a wireless link between the receiving device and the device in which digital rights management system 700 is implemented.
As will be appreciated from reading the foregoing, various embodiments of the present invention provide systems and methods for distributing content objects incorporating one or more digital rights management schemes. In some cases, such systems and methods may provide for distribution of rights managed content to one or more devices that are communicably coupled to the device in which digital rights management system 700 is implemented. Further, such distribution may be accomplished without an incremental fee to the user distributing the content to another device. It should also be noted that rights managed content may be distributed without the aid of a personal computer, or without access to the Internet as the content is maintained on a device local to the distribution. Further, because the distributed content may be maintained on a mobile storage medium that is wirelessly accessible, the content may be accessed and consumed immediately without having the need to go back to a specific location (e.g., a home where a personal computer is located) to retrieve or re-encode the desired content in a form accessible to a consuming device (e.g., a consumer electronic device).
Turning to FIG. 5, a diagram 400 illustrates a method for content object delivery in accordance with one or more embodiments of the present invention. A content company 310 represents many content owners in licensing digital content distribution by both online retailers 315 and wireless retailers 320. Wireless retailers 320 and online retailers 315 in turn distribute the licensed content objects to consumers (e.g., to UMCS device 410 maintained by the user) under license from content company 310. UMCS 410 is able to receive content from any of online retailers 315, wireless retailers 320 and/or self maintained content equipment such as, for example, an audio capture device 420 or a video capture device 415. UMCS 410 is enabled to output content to one or more consumer devices via a common interface. In some cases, the common interface is a wireless interface. Such a wireless interface may be, but is not limited to an 802.11 wireless interface. In one particular case, the wireless interface is an 802.11(i) interface.
In various cases, the content objects are received in a particular format and stored on UMCS 410 in the received format. In other cases, UMCS 410 performs a format conversion on the received content object before it is stored. The format in which the content objects are stored on UMCS 410 is referred to herein as a “native format”. Further, the received content object may require some form of digital rights management. In such cases, the particular form of digital rights management is associated with the received content object. In some cases, the received content object may be decrypted before being stored to the memory of UMCS 410. In such cases, any access to the content object from the memory requires satisfaction of the digital rights management requirements. In other cases, the content object is stored in its encrypted or encoded condition, and only when the content object is accessed from the memory is digital rights management applied. In such cases, a tag may be stored with the content object that indicates both the native format of the content object and a particular digital rights management scheme/key that may be used to decrypt the particular content object.
Turning now to FIG. 6, a flow diagram 600 depicts a method in accordance with one or more embodiments of the present invention for performing digital rights management on data stored local to an application device. Following flow diagram 600, information is received via an antenna associated with the UMCS device (block 605). The information received via the antenna is demodulated and buffered (blocks 610-615). It is next determined if the device with which the UMCS is communicating has been authenticated (block 620). Where no authentication is complete (block 620), an authentication can be performed immediately to satisfy the authentication requirement, or the process may simply end (block 655). Such authentication may be performed using any authentication approach known in the art. In other embodiments of the present invention, only information from a previously authenticated and/or bound device may be received. In such cases, block 620 and block 655 may not be necessary.
Where the authentication requirement is satisfied (block 620), it is determined whether the received information is to be the subject of a storage or retrieval from the storage component associated with the UMCS device (block 625). Where the received information is to be stored to the storage component (block 625), it is determined whether the information is to be encoded (block 630). Where the information is to be encoded (block 630), the appropriate encoding is performed (block 635). In some cases, the encoding provides for a format conversion from a received format to a native format. As previously discussed, in some embodiments of the present invention content objects are stored in the format in which they are received. In such cases, the aforementioned encoding is not performed. In other embodiments of the present invention, content objects are first encoded to change the native format in which the content object are stored. It is then determined whether some form of digital rights management is to be applied to the information (block 640). Where digital rights management is to be applied (block 640), the appropriate digital rights management is indicated in relation to the content object (block 645). Finally, the information is stored to the storage component of the UMCS device (block 850) and the process ends (block 655).
Otherwise, where information is to be retrieved from the storage component of the UMCS device (block 625), the indicated information is retrieved from the storage component (block 660). In addition, it is determined if a digital rights management is to be performed in relation to the retrieved information (block 665). Where digital rights management is to be performed in relation to the retrieved information (block 665), the appropriate digital rights management module is accessed (block 670) and the retrieved information is unwrapped or otherwise decrypted (block 675). It is next determined whether the information is to be furnished to the requestor in a format other than the native format (block 680). Where the information is to be provided in other than the native format (block 880), the appropriate decoding (i.e., format conversion) is performed (block 685). Finally, the information is modulated (block 890) and transmitted via the antenna (block 695).
In conclusion, the present invention provides novel systems, devices, methods and arrangements for implementing hands free operational environments. It should be noted that while a number of different data sharing approaches have been discussed herein, that one of ordinary skill in the art upon reading this disclosure would appreciate other approaches that may be implemented in accordance with various embodiments of the present invention. In particular, while detailed descriptions of one or more embodiments of the invention have been given above, various alternatives, modifications, and equivalents will be apparent to those skilled in the art without varying from the spirit of the invention. Therefore, the above description should not be taken as limiting the scope of the invention, which is defined by the appended claims.
