Abstract

Methods and apparatus for managing devices and content in a network environment. In one implementation, a method of adding a client as a member of a hub network includes: detecting a client connected to a server in a hub network; authenticating said client; authorizing said client; and adding said client as a member in said hub network.

Claims

1-31. -31. (canceled)

32. A method of removing a client as a member of a hub network, comprising:

triggering removal of a client as a member of a hub network;

disabling all licenses stored by said client corresponding to content data bound to said hub network; and

removing said client as a member in said hub network so that said client is no longer a member of said hub network.

33. The method of claim 32, wherein:

said server will provide a license for content data bound to said hub network only to members of said hub network.

34. The method of claim 32, wherein:

triggering removal of said client includes receiving a removal request from said client.

35. The method of claim 32, wherein:

triggering removal of said client includes receiving a revocation notification that said client is no longer to be authorized to be a member of a hub network.

36. The method of claim 35, further comprising:

adding said client to a revocation list stored on said server.

37. The method of claim 36, further comprising:

sending said revocation list including said client to a second client in said hub network.

38. The method of claim 36, further comprising:

sending said revocation list including said client to a second server in a second hub network.

39. The method of claim 35, further comprising:

adding said client to a revocation list corresponding to a root license stored on said server;

wherein said root license corresponds to locked content data stored on said server and is bound to said hub network.

40. The method of claim 32, wherein:

disabling said licenses includes sending a disable request to said client indicating one or more license to be disabled.

41. The method of claim 32, wherein:

disabling said licenses includes updating respective root licenses corresponding to said disabled licenses.

42. The method of claim 41, further comprising:

declining to renew said disabled licenses for said client.

43. The method of claim 32, wherein:

removing said client as a member includes updating respective root licenses corresponding to said disabled licenses.

44. The method of claim 32, wherein:

said server does not remove said client as a member until all of said disabled licenses have expired.

45. The method of claim 32, further comprising:

decreasing a device count after removing said client as a member;

wherein said device count indicates the number of members in said hub network.

46-50. -50. (canceled)

51. A method of disconnecting a client from a hub network, comprising:

disconnecting a client from a hub network;

setting an expiration time for a license stored on said client; and

comparing said expiration time to a clock of said client;

wherein said license corresponds to locked content data stored on said client and is bound to said hub network.

52. The method of claim 51, wherein:

said license indicates an expiration period, and

said expiration period indicates an amount of time for which said sub-copy license is valid.

53. The method of claim 51, further comprising:

setting said expiration time according to said expiration period including resetting said expiration time if said expiration time was previously set to a different value.

54. The method of claim 51, wherein:

disconnecting said client includes said client leaving a local environment of a server of said hub network, and

said local environment is a limited area defined relative to said server.

55. The method of claim 51, wherein:

said clock is a secure client clock.

56. The method of claim 51, further comprising:

when comparing said expiration time to said clock indicates that said expiration time has been reached, disabling said license;

wherein said client will not decrypt said locked content data when said license is disabled.

57. The method of claim 51, further comprising:

attempting to request a new license from a server in said hub network.

58. The method of claim 51, further comprising:

attempting to reconnect said client to said hub network.
