Abstract

Certain embodiments of the present invention provide an archive management application that operates within a host application to provide access to an archive and/or allow access to and/or modification of files in an archive using the host application'"'"'s interface, instead of operating as a separate standalone archive management application. In an embodiment of the present invention, a file archiving system may include a user interface component, a file management component and a compression/extraction engine component. The user interface component may include an enhanced user interface of a host application that provides an interface for a user. The file management component may include a central directory that provides a representation of the contents of an archive. The compression/extraction engine component may include a file size module and/or a security module. The file size module may be used to compress and/or decompress a file in an archive. The security module may be used to encrypt, decrypt, digitally sign and/or authenticate a file in an archive.

Claims

1. A method for accessing an archive, said method including:

receiving first access data from a user seeking to gain access to an archive;

receiving second access data;

using said first access data and said second access data to form an access data result;

comparing said access data result to security information stored in said archive to determine an access control decision; and

providing access to data in said archive based on said access control decision.

2. The method of claim 1 wherein at least one of said first access data and said second access data is a portion of a key.

3. The method of claim 1 wherein at least one of said first access data and said second access data is a portion of a password.

4. The method of claim 1 wherein said security information is stored in a repository in said archive.

5. The method of claim 4 wherein said archive includes a file and said repository is separate from said file.

6. The method of claim 4 wherein said repository is encrypted.

7. The method of claim 4 wherein said repository is accessible by a plurality of computing devices.

8. The method of claim 4 wherein said repository is accessible from a remote location.

9. The method of claim 4 wherein said repository is accessible from a plurality of locations.

10. The method of claim 1 wherein said security information includes a digital certificate.

11. The method of claim 1 wherein said security information includes a password.

12. The method of claim 1 wherein said security information includes a plurality of passwords.

13. The method of claim 1 wherein said security information includes a private key.

14. The method of claim 1 wherein said security information includes a public key.

15. The method of claim 1 wherein said security information includes a contingency key.

16. The method of claim 1 wherein said security information includes key material.

17. The method of claim 1 wherein said security information includes a segmented key.

18. The method of claim 1 wherein said security information includes biometric data.

19. The method of claim 4 wherein said repository resides on a computing device.

20. The method of claim 4 wherein said repository resides on a portable storage device.

21. The method of claim 4 wherein said repository is a shared repository.

22. The method of claim 21 wherein the Lightweight Directory Access Protocol is used to access said shared repository.

23. The method of claim 1 wherein access to said archive is restricted to users providing access data matching said security information.

24. The method of claim 23 wherein said data includes a user token.

25. The method of claim 24 wherein said user token is a Universal Serial Bus token.

26. The method of claim 23 wherein said data includes a portable token.

27. The method of claim 26 wherein said portable token is a portable Smart Card.

28. The method of claim 23 wherein said data includes biometric data.

29. The method of claim 23 wherein said data includes a password.

30. The method of claim 23 wherein said data includes a Personal Identification Number code.

31. The method of claim 1 wherein said archive is a .Zip archive.

32. A method for accessing a file in an archive, said method including:

receiving first access data from a user seeking to gain access to a file in an archive;

receiving second access data;

using said first access data and said second access data to form an access data result;

comparing said access data result to security information stored in said archive to determine an access control decision; and

providing access said file in said archive based on said access control decision.

33. A method for accessing a central directory in an archive, said method including:

receiving first access data from a user seeking to gain access to a central directory in an archive;

receiving second access data;

using said first access data and said second access data to form an access data result;

comparing said access data result to security information stored in said archive to determine an access control decision; and

providing access said central directory in said archive based on said access control decision.

34. A method for accessing an archive, said method including:

receiving first access data from a user seeking to gain access to an archive;

receiving second access data;

using said first access data and said second access data to form an access data result;

comparing said access data result to security information stored in a repository to determine an access control decision; and

providing access to said archive based on said access control decision.

35. The method of claim 34 wherein said security information is stored in a repository in said archive.

36. The method of claim 34 wherein said security information is stored in a repository outside said archive.

37. A method for controlling access to a archive, said method including:

associating first security information and second security information with an archive;

storing said first security information in a first repository outside of said archive;

storing said second security information in at least one of said first repository and a second repository;

receiving an access request, said access request including first access data and second access data;

comparing said first access data to said first security information and said second security information to determine if said first access data matches at least one of said first security information and said second security information;

comparing said second access data to said first security information and said second security information to determine if said second access data matches at least one of said first security information and said second security information;

providing access to said archive when both said first access data and said second access data match said security information.

38. The method of claim 37 wherein said second repository is outside of said archive.

39. The method of claim 37 wherein said second repository is inside said archive.

40. A method for controlling access to a archive, said method including:

associating first security information and second security information with an archive;

storing said first security information in a first repository inside of said archive;

storing said second security information in at least one of said first repository and a second repository;

receiving an access request, said access request including first access data and second access data;

comparing said first access data to said first security information and said second security information to determine if said first access data matches at least one of said first security information and said second security information;

comparing said second access data to said first security information and said second security information to determine if said second access data matches at least one of said first security information and said second security information;

providing access to data in said archive when both said first access data and said second access data match said security information.

41. The method of claim 40 wherein said second repository is outside of said archive.

42. The method of claim 40 wherein said second repository is inside said archive.
