Abstract

A trusted system having at least one repository for controlling use of digital works in accordance with usage rights associated with the digital works. The system comprises means for receiving a request to access a digital work in accordance with usage rights associated with the digital work, the usage rights specifying a manner of access and indicating a security class, means for determining a security level of a repository controlling the requested access, and means for granting the request and permitting exercise of the manner of access specified in the usage rights associated with the digital work in accordance with the usage rights if the security level of the repository corresponds to the security class specified in the usage rights associated with the digital work. The security class indicates a security level of a repository that can access the digital work, and the usage rights are expressed with a grammar. In addition, an authorization object is used for identification of the repository, the physical integrity of the repository is secured, and digital works are accessed only through a transmission transaction protocol.

Claims

1. In a trusted system having at least one repository for controlling use of digital works in accordance with usage rights associated with the digital works, a method comprising:

receiving a request to access a digital work in accordance with usage rights associated with the digital work, the usage rights specifying a manner of access and indicating a security class;

determining a security level of a repository controlling the requested access; and

if the security level of the repository corresponds to the security class specified in the usage rights associated with the digital work, granting the request and permitting exercise of the manner of access specified in the usage rights associated with the digital work in accordance with the usage rights, wherein the security class indicates a security level of a repository that can access the digital work and the usage rights are expressed with a grammar,

wherein an authorization object is used for identification of the repository, the physical integrity of the repository is secured, and digital works are accessed only through a transmission transaction protocol.

2. A method as recited in claim 1, wherein said grammar comprises one or more symbols from a first set of predetermined symbols to define a valid sequence of symbols to indicate the manner of access.

3. A method as recited in claim 1, wherein the usage rights further specify a digital ticket that must be possessed as a condition for granting the request and permitting exercise of the manner of access specified in the usage rights associated with the digital work.

4. A method as recited in claim 1, wherein the usage rights further specify an access specification indicating the security class.

5. A method as recited in claim 1, wherein the security level indicated by the security class is a minimum security level of the repository that can exercise the manner of access specified in the usage rights.

6. A method as recited in claim 1, wherein the manner of access is copying the digital work to the repository.

7. A method as recited in claim 1, wherein the manner of access is rendering the digital work with the repository.

8. A method as recited in claim 1, wherein digital works cannot be stored on removable storage.

9. A method as recited in claim 1, wherein the digital work is a software program and the manner of access is executing the software program.

10. A method as recited in claim 9, wherein the executing step comprises running the computer program in a dedicated address space and preventing access to any memory containing system code or other digital works.

11. A method as recited in claim 1, further comprising:

detecting any attempts at tampering with the repository; and

if a level of attempts at tampering with the repository exceeds a predetermined threshold, causing the repository to save only document description records and destroying any digital identifiers of documents.

12. A method as recited in claim 11, wherein the predetermined threshold defines a number of attempts at tampering and wherein the level is a number of attempts at tampering.

13. A method as recited in claim 11, further comprising modifying any certificates of authenticity to indicate that the security of the repository has been compromised.

14. A method as recited in claim 11, further comprising erasing the contents of designated documents if the level of attempts at tampering with the repository exceed the predetermined threshold.

15. A method as recited in claim 11, further comprising the repository communicating attempts at tampering to another device.

16. A method as recited in claim 11, further comprising activating an alarm when tampering is detected.

17. A method as recited in claim 1, further comprising maintaining communications with a remote security systems.

18. A method as recited in claim 17, wherein the communications comprise at least one of reporting transactions and reporting attempts to circumvent security of the repository.

19. A method as recited in claim 1, further comprising a user interface for permitting a user to communicate with the repository.

20. A method as recited in claim 19, wherein the user interface and the repository are embedded on the same device.

21. A method as recited in claim 1, further comprising recording the history of transactions with the repository.

22. A method as recited in claim 1, wherein the repository is password protected.

23. A method as recited in claim 1, further comprising preventing setting of a clock of the repository without authorization.

24. A method as recited in claim 1, wherein the digital work is a bond or a stock certificate.

25. A trusted system having at least one repository for controlling use of digital works in accordance with usage rights associated with the digital works, the system comprising:

means for receiving a request to access a digital work in accordance with usage rights associated with the digital work, the usage rights specifying a manner of access and indicating a security class;

means for determining a security level of a repository controlling the requested access; and

means for granting the request and permitting exercise of the manner of access specified in the usage rights associated with the digital work in accordance with the usage rights if the security level of the repository corresponds to the security class specified in the usage rights associated with the digital work, wherein the security class indicates a security level of a repository that can access the digital work and the usage rights are expressed with a grammar,

wherein an authorization object is used for identification of the repository, the physical integrity of the repository is secured, and digital works are accessed only through a transmission transaction protocol.

26. A system as recited in claim 25, wherein said grammar comprises one or more symbols from a first set of predetermined symbols to define a valid sequence of symbols to indicate the manner of access.

27. A system as recited in claim 25, wherein the usage rights further specify a digital ticket that must be possessed as a condition for granting the request and permitting exercise of the manner of access specified in the usage rights associated with the digital work.

28. A system as recited in claim 25, wherein the usage rights further specify an access specification indicating the security class.

29. A system as recited in claim 25, wherein the security level indicated by the security class is a minimum security level of the repository that can exercise the manner of access specified in the usage rights.

30. A system as recited in claim 25, wherein the manner of access is copying the digital work to the repository.
