## Title
Method and system for restricted biometric access to content of packaged media

## Abstract

A system, method, and user device for restricting access to the content of media over a network. Biometric information is collected and compared against pre-stored biometric information of a user to authenticate the identity of the user. The user then requests access to the content of a medium. Access is permitted to the requested content if the content is identified as content, or indicia identifying the content, that the user previously uploaded to the server. Access is denied to the requested content if the content is not identified as content, or indicia identifying the content, that the user previously uploaded to the server.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. application Ser. No. 09/797,516, filed on Mar. 1, 2001, the disclosure of which is incorporated herein by reference.


BACKGROUND OF THE INVENTION
The present invention relates to a system and method for storing and distributing the content of packaged media. In particular, the present invention relates to a system and method for storing and distributing the content of packaged media over a network in a restricted manner.
Many consumers today have CD, DVD, MD or VHS packaged media. In order for consumers to access the content on their media, the consumers need to have the media immediately accessible to them. This requires that consumers wishing to enjoy their media from any place other than where the media is located must make a choice as to which media to take with them as they move about.
Alternatives to date have been for the consumer to upload the content of the media, in particular media in the CD audio format, for storage in an unsecured Internet accessible server. The consumer can then access the content through a network connection using portable devices. As a result, some copyright holders have had a problem with these alternatives since the alternatives offer the opportunity for people who do not own the media to easily access the content of the media from the server storage. For example, a consumer could purchase a CD and, using a personal computer (PC), upload the content stored on the CD into the storage of an unsecured server. This would then allow many other people who do not own the CD to use a network connection to access the content of the CD from the server storage.
There is thus a need for a system and method for allowing a user secure access to his or her personally owned packaged media from any location.
SUMMARY OF THE INVENTION
The present invention provides a system, method and a user device for restricting access to the content of media over a network. Biometric information of the user verifies the identity of the user, and allows a biometrically authenticated user to access the content of media that the user previously stored or identified on a server on a network.
To accomplish this, biometric information of the user is obtained with a biometric device associated with a user device. This biometric information is compared against pre-stored biometric information of the user to authenticate the identity of the user. The user requests access to the content of a medium stored on a server on the network. The user is provided access to the requested content if the content is identified as content, or indicia identifying the content, that the user device previously uploaded to the server. The user is denied access to the content if the content is not identified as content, or indicia identifying the content, that the user device previously uploaded to the server.

DETAILED DESCRIPTION
The present invention provides a system for restricting access to the content of packaged media over a network to biometrically authenticated users who previously uploaded the content of packaged media, or indicia identifying the content of packaged media, to a server on the network. In a preferred embodiment of the present invention, this restricted access is provided through a biometric registration, a subsequent biometric authentication, and identification of the content requested by the user as corresponding to the content, or indicia identifying the content, of packaged media that the user previously uploaded to the server.
FIG. 1 is a diagram of a distributed computer network system 10 in accordance with the present invention. System 10 includes a network server, for example, content storage and management server 15, connected via network 20, for example, the Internet, to a client computer, for example, user PC 25. User PC 25 includes components normally found in a personal computer such as, for example, a memory, an operating system, a browser, and a content playing module. In accordance with the present invention, user PC 25 also has a content access managing module, referred to herein as a PC module. This module is discussed in greater detail below.
User PC 25 also preferably has a biometric device 27 for measuring a unique human characteristic of a user referred to herein as biometric information. Preferably, the biometric information will be a fingerprint or a voice pattern. Conventional fingerprint recognition and/or voice recognition technology may be used to collect and analyze the biometric information. Although these are the preferred types of biometric information, the present invention is not so limited, and other types of biometric information may include retina pattern, iris pattern, scent pattern, voice pattern, DNA pattern, heat pattern, facial image or any other human characteristic uniquely identifying a particular individual. Biometric device 27 may be built into user PC 25 or may be an external device connected to PC 25 through a cable or a wireless connection. Biometric device 27 may be a device that collects the biometric information of the user and then transmits the biometric information to a server 15, or another server on the network connected to server 15, for biometric authentication of the user. Alternatively, biometric device 27 may be a device that both collects the biometric information of a user, biometrically authenticates the user and then provides an authorization signal to server 15 or another server on the network connected to server 15.
Server 15 contains hardware and software for sending and receiving information over the network, such as web pages or files over the World Wide Web. Server 15 may be a typical web server or any other computer network server or automated system capable of communicating with other computers over a network, including the Internet, wide area networks or local area networks. In accordance with the present invention, server 15 includes components normally found in a network server, including, for example, a memory and an operating system. Server 15 also preferably includes a registration database, a content database, and a content access managing module, referred to herein as a network module. These databases and module are discussed in greater detail below.
Also connected to network 20 via wireless LAN 30 is a user personal digital assistant (PDA) 35. PDA 35 is a portable user device having wireless capability. PDA 35 includes components normally found in a PDA, including, for example, a memory, an operating system, a browser, and a content playing module. In accordance with the present invention, PDA 35 also preferably has a biometric device 37 for measuring biometric information of the user. Like user biometric device 27, biometric device 37 may be built in to PDA 35 biometric device or an external device connected to PDA 35 through a cable or wireless connection. Additionally, like user PC 25, biometric device 37 may be a device for collecting biometric information with biometric authentication occurring at server 15, or another server in communication with server 15, or may be a device that both collects the biometric information and biometrically authenticates the user.
In accordance with the present invention, PDA 35 also preferably includes a content access managing module, referred to herein as a PDA module. This module is discussed in greater detail below. Alternatively, a portable memory device, such as a CD, floppy disk, memory stick, etc. containing the PDA module may be inserted or plugged into PDA 35.
Although user PC 25 and PDA 35 are shown by way of example in FIG. 1 for interacting with server 15, it should be understood that in lieu of, or in addition to user PC 25 and PDA 35, other computer devices, such as set-top boxes, digital televisions, Internet appliances, portable computers, cellular telephones, MP3 players, etc., may be used for this purpose It also should be appreciated that although only two user devices are depicted in FIG. 1, server 15 is typically connected to many such user devices.
FIG. 2 provides a further description of the PC module. As discussed above, user PC 25 has components normally found in a personal computer, such as, for example, memory 40, operating system 45, browser 50 and content playing module 60. Content playing module 60 includes compression/decompression (CODEC) module 62. In accordance with the present invention, PC module 65 includes biometric authentication module 70, content recognition module 75, and server storage module 80.
If biometric device 27 only collects a user's biometric information, but does not biometrically authenticate the user, biometric authentication module 70, referred to hereinafter as biometric module 70, collects the user's biometric information. Biometric module 70 then transmits this biometric information to server 15, and server 15 biometrically authenticates the user. Alternatively, if biometric device 27 both collects the user's biometric information and biometrically authenticates the user, then biometric module 70 receives a biometric authentication signal from biometric device 27. Biometric module 70 then transmits this authentication signal to server 15.
Content recognition module 75, referred to hereinafter as recognition module 75, (i) recognizes the content of a CD (or other media) from a unique code or identifier read from the CD, (ii) transmits the unique code or identifier to server 15, (iii) receives responsive identification of the content from the server, and (iv) displays the responsive identification to the user. In the alternative, rather than recognition module 75 reading a unique code or identifier from the CD identifying the CD's content, the entire content of the CD can be uploaded to server 15 by server storage module 80.
For example, recognition module 75 can read a conventional digital fingerprint or identification code on a CD that uniquely identifies the content stored on the CD such as, for example, the bit pattern of the table of contents (TOC) portion of the CD. Recognition module 75 transmits the CD fingerprint or identification code to a database on server 15. If the content of the CD was previously stored on server 15, the CD's content does not require uploading to server 15.
Following identification of the CD, server storage module 80, referred to hereinafter as storage module 80, transmits the user's instruction to add the CD's content to an access rights portfolio of the user. The user's access rights portfolio may be located on user PC 25, a combination of user PC 25 and server 15, or preferably solely on server 15.
Alternatively, when the content of a CD is not already stored on server 15, storage module 80 uploads the content of the CD to server 15. The identity of such content similarly is included in the user's access rights portfolio.
FIG. 3 provides a further description of the registration database, content database and network module of server 15. As discussed above, server 15 includes components normally found in a network server, including, for example, memory 85 and operating system 90. In accordance with the present invention, server 15 also includes registration database 95, content database 100, and network module 105. Registration database 95 stores biometric information of registered users. This information is compared against biometric information transmitted by users seeking access to media content to authenticate these users. Content database 100 stores the actual content of packaged media to be accessed by authenticated users.
Network module 105 includes biometric authentication sequence module 110, referred to hereinafter as biometric module 110, and content indexing module 115, referred to hereinafter as indexing module 115. Biometric module 110 includes software for registering users, initiating access rights to identified content, and granting access to previously identified content. Indexing module 115 indexes the content of media stored in content database 100. For example, indexing module 115 indexes the song titles and track numbers of a CD, or the picture names and chapter numbers of a DVD. Indexing module 115 also stores, for each registered user, pointers to the content stored in content database 100 for which the user is permitted access. This scheme avoids redundant storage of content to which many users have access rights.
FIG. 4 further illustrates PDA 35. As discussed above, PDA 35 includes components normally found in a PDA, including, for example, memory 120, operating system 125, browser 130 and content playing module 135. Content playing module 135 includes compression/decompression (CODEC) module 137. In accordance with the present invention, PDA 35 also includes content access managing module 140, referred to hereinafter as PDA module 140. PDA module 140 may be included in memory 120. Alternatively, PDA 35 may include means for receiving a portable memory device, such as, a CD, a floppy disk, a removable FLASH memory (preferably a Sony Memory Stick) etc., containing PDA module 140.
PDA module 140 includes biometric authentication module 145, referred to hereinafter as biometric module 145. If biometric device 37 only collects a user's biometric information, but does not biometrically authenticate the user, biometric module 145 collects the user's biometric information. Biometric module 145 then transmits this biometric information to server 15, and server 15 biometrically authenticates the user. Alternatively, if biometric device 37 both collects the user's biometric information and biometrically authenticates the user, biometric device 37 transmits a biometric authentication signal to biometric module 145. Biometric module 145 then transmits this authentication signal to server 15.
Alternatively, if a portable memory device, such as, a removable FLASH memory contains PDA module 140 inserting the removable FLASH memory into a portable device, such as, PDA 35 migrates to PDA 35 the biometric authentication functionality of PDA module 140, including biometric authentication module 145. In accordance with the present invention, PDA 35 then also has biometric device 37 for measuring biometric information of the user. Biometric device 37 may be built into PDA 35 or may be an external device connected to PDA 35 through a cable or wireless connection. Additionally, biometric device 37 may be a device for collecting biometric information with biometric authentication occurring at server 15, or another server in communication with server 15, or may be a device that both collects the biometric information and biometrically authenticates the user.
Referring now to FIGS. 1 and 2, in a preferred embodiment, user PC 25 communicates with server 15 via network connection 20. The user originally accesses server 15 through notification of the URL. The user then registers for a service to authenticate the identity of the user to permit secured access to the content of a packaged medium owned by the user, for example, the content of a CD in audio format. This registration involves providing, e.g., the user's name, address, phone number, email address, biometric information, etc.
As part of this registration, the user activates biometric device 27 to measure biometric information of the user. Biometric module 70 of user PC 25 collects the biometric information of the user from the biometric device 27. User PC 25 transmits the biometric information from biometric module 70 to registration database 95 of server 15. Registration database 95 stores the biometric information of the user. Upon storage of the user's biometric information in registration database 95, the registration is complete.
Alternatively, as described in connection with FIG. 2, if biometric device 27 is a device that both collects the biometric information and authenticates the user's identity, the user activates biometric device 27 to measure the biometric information of the user. Biometric device 27 stores this biometric information in biometric device 27, and also transmits a signal to biometric module 70 of user PC 25 indicating that this biometric information was collected and stored. Biometric module 70 then transmits this signal to server 15, and the registration is complete.
After registration, the user can access server 15 using, e.g., conventional browser 50 of PC 25 or browser 130 of PDA 35. The initial access is accomplished in a conventional manner. However, after initial access is affected, server 15 activates biometric module 110 for the purpose of recognizing and authenticating the identity of the user. For example, if the user is using PC 25 to access server 15, the user will be prompted to provide the biometric information of the user to biometric device 27 of PC 25. In that case, biometric module 70 collects the biometric information, and transmits the biometric information to biometric module 110 of server 15. Biometric module 110 compares the biometric information received from biometric module 70 against the previously stored copy of the biometric information of the user stored in registration database 95 for the purpose of authenticating the identity of the user. If the biometric information received from biometric module 70 matches the biometric information stored in registration database 95 for the user, a verification code is generated and access is granted to the user to appropriate content. If the biometric information received from biometric module 70 does not match the biometric information stored in registration database 95, a denial code is generated and access is denied to the user for any content.
Alternatively, if biometric device 27 is used to biometrically authenticate the user (not simply collect the biometric information for authentication by server 15), after registration, the user accesses server 15 using browser 50. The user activates biometric device 27 to collect the user's biometric information. Biometric device 27 compares the biometric information against the previously stored copy of the biometric information stored in biometric device 27 (or PC 25) for the purpose of authenticating the identity of the user. If the biometric information matches the previously stored biometric information, an authentication signal is generated. If the biometric information does not match the previously stored biometric information, a denial code is generated. If biometric device 27 generates an authentication signal, biometric device 27 transmits the authentication signal to biometric module 110 of server 15.
After a user accesses server 15 and his or her identity is authenticated, e.g., as part of the registration process or during any access to server 15 following registration, the user may wish to add media content to his or her access rights portfolio. To do so, the user inserts media, e.g., a CD into, e.g., the disc drive of user PC 25. Recognition module 75 of user PC 25 reads a conventional digital fingerprint or identification code of the CD that uniquely identifies the content stored on the CD. For example, recognition module 75 may read the bit pattern of the TOC portion of the CD to uniquely identify the content stored on the CD. Recognition module 75 transmits the CD fingerprint or identification code to registration database 95 of server 15. Registration database 95 communicates with indexing module 115 to identify the content requested by the user. Indexing module 115 maps the CD fingerprint or identification code to the identity of the content of the CD. If indexing module 115 identifies the content of the CD as content already stored in content database 100, recognition module 75 receives responsive identification of the content from server 15, and displays the responsive identification of the content to the user. Alternatively, if indexing module 115 does not identify the content of the CD as content already stored on server 15, the disc drive of user PC 25 reads the content of the CD, and storage module 80 uploads the content of the CD to content database 100 of server 15.
After PC 25 uploads to server 15 either the unique fingerprint or code from the CD, or the content of the CD, content indexing module 115 manages and provides an index of this content as content that the user may access in a user's access rights portfolio. Alternatively, this index may be maintained by PC module 65 or on a combination of both server 15 and PC module 65. Preferably, the portfolio is included on server 15 for security and to accommodate the user's access to the content from different user devices. Once the content is identified in the user's access rights portfolio on server 15, the user can subsequently access the content from any location and from any device having a biometric device similar to biometric device 27 or biometric device 37.
For example, after the user registers and establishes the user's access rights portfolio on server 15, the user can access the content identified in the access rights portfolio from any location using PDA 35. Turning to FIGS. 1 and 4, PDA 35 is connected to server 15 via wireless network connection 30 and network 20. The user accesses server 15 using browser 130 of PDA 35. To authenticate the user's identity, the user activates biometric device 37 to measure biometric information of the user. Biometric module 145 collects the biometric information of the user, and transmits the biometric information to biometric module 110 of server 15. Biometric module 110 compares the biometric information received from biometric module 145 against the previously stored copy of the biometric information of the user stored in registration database 95. If the biometric information received from biometric module 145 matches the biometric information stored in registration database 95 for the user, a verification code is generated and access is granted to the user to the content identified in the user's access rights portfolio. If the biometric information received from biometric module 145 does not match the biometric information stored in registration database 95, a denial code is generated and access is denied to the user to any content.
Alternatively, if biometric device 37 is used to both collect the biometric information and biometrically authenticate the user, after registration, the user accesses server 15 using browser 130. The user activates biometric device 37 to collect the user's biometric information. Biometric device 37 then compares this biometric information against the previously stored copy of the biometric information in biometric device 37 or PDA 35 for the purpose of authenticating the identity of the user. If the biometric information matches the previously stored biometric information, an authentication signal is generated. If the biometric information does not match the previously stored biometric information, a denial code is generated. If biometric device 37 generates an authentication signal, biometric device 37 transmits the authentication signal to biometric module 110 of server 15.
After the identity of the user is biometrically authenticated, the user can access from PDA 35 the user's access rights portfolio on server 15. From the user's access rights portfolio, the user can choose the content that the user desires to have played back on PDA 35. Indexing module 115 is used to easily display to the user a list of the content for which the user has access rights. Indexing module 115 assists the user in searching for available content, e.g., song titles or a playlist. The user may have previously compiled a playlist with user PC 25, e.g., and uploaded the playlist to server 15 allowing access to the playlist through a network connection using a portable device, e.g., PDA 35. The user chooses the content that the user desires to have played back on PDA 35 using content playing module 135. Typically, the content stored on server 15 is stored in MP3 or ATRAC format. Content database 100 of server 15 transmits the requested content to PDA 35. The playback can be accomplished using conventional streaming audio or, alternatively, downloading the content to the user device, e.g., PDA 35. Preferably, the playback is accomplished using conventional streaming audio.
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is, therefore, to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
