Abstract

An apparatus, method and computer program for the management of digital information bearing digital signatures is disclosed. The invention includes an apparatus for the management of digital information in a database. This apparatus further includes the means for importing the digital information; means for processing the digital information, wherein the digital information may include at least one digital document, at least one digital signature, at least one public key certificate, at least one archival policy; means for obtaining data from an external server and means for exporting output information from the apparatus, whereby a user when importing the digital information to the apparatus, causes the digital information to be processed thereby generating the output information that is stored in the database.

Claims

1-42. -42. (Cancelled)

43. An apparatus for the management of digital information in a database, comprising:

means for importing said digital information;

means for processing said digital information;

wherein said digital information may include;

at least one digital document,

at least one digital signature,

at least one public key certificate,

at least one archival policy for each document; and

means for exporting output information generated from said digital information from said apparatus, whereby a user when importing said digital information to said apparatus, causes said digital information to be processed thereby generating said output information generated from said digital information that is stored in said database.

44. An apparatus according to claim 43, further including a means for obtaining data from a external server, said data including time stamp information.

45. An apparatus according to claim 44, wherein said data includes revocation information, and bound with said digital information in said database.

46. An apparatus according to claim 44, wherein said external server belongs to a trusted third party.

47. An apparatus according to claim 43, wherein said at least one archival policy further includes at least one of:

an owner identity, payload information, archival period, access mode to server, user access rights, logical file location in repository, cryptographic details, and payment model.

48. An apparatus according to claim 43, wherein said means for processing said digital information when completed, returns a response to said user.

49. An apparatus according to claim 47, wherein said means of exporting said output information from said database is allowed based on the said user access rights defined in said archival policy.

50. An apparatus according to claim 43, wherein said means of importing and means of exporting said output information from said database is in a network.

51. An apparatus according to claim 50, wherein said network is a client-server configuration or peer-to-peer.

52. An apparatus according to claim 51, wherein said client-server or peer-to-peer configuration is based on at least one selected from the group consisting of:

the web, electronic mail, transfer protocol, and wireless.

53. A system for managing digital information, including:

a receive means for receiving said digital information;

a communication means for obtaining data from at least one external source; and

a processing means for formatting said digital information into an archival document using said data, and storing said archive or document in a database.

54. A system as claimed in claim 53, wherein said digital information includes:

at least one digital document,

at least one digital signature,

at least one public key certificate,

at least one archival policy.

55. A system as claimed in claim 54, wherein said at least one archival policy includes at least one of:

an owner identity,

payload information,

archival period,

access mode to server,

user access rights,

logical file location in repository,

cryptographic details, or

payment model.

56. A system as claimed in claim 54, further including an export means to enable a user to access and/or retrieve said archival document or said digital information.

57. A system as claimed in claim 54, wherein a person inputs said digital information to said receive means, and, following said formatting by said processing means, a response is returned to said person.

58. A system as claimed in claim 54, wherein said data includes certification, validation, time stamp information and/or revocation information, and is bound with said digital information in said database.

59. A system as claimed in claim 54, wherein said at least one external source belongs to a trusted third party, and said communication means determines which digital information requires certification and/or validation, and then communicates with the relevant database and/or server.

60. A system as claimed in claim 56, wherein said export allows access or retrieval by a user based on the said user access rights defined in said archival policy.

61. A system as claimed in claim 56, wherein said receive means and said export means are accessed via a network, said network being a client-server configuration or a peer-to-peer configuration.

62. A system as claimed in claim 61, wherein said client-server or peer-to-peer configuration is selected from the group consisting of:

web based, electronic mail based, or file transfer protocol based, and wireless based.

63. A computer program product including a computer usable medium having computer readable program code and computer readable system code embodied on said medium for managing digital information stored on a storage means within a data processing system, said computer program product further including computer readable code within said computer usable medium for:

receiving said digital information;

obtaining data from at least one external source; and

formatting said digital information into an archival document using said data, and storing archival document in said storage means.

64. A computer program product as claimed in claim 63, wherein said digital information includes:

at least one digital document,

at least one digital signature,

at least one public key certificate,

at least one archival policy.

65. A computer program product as claimed in claim 64, wherein said at least one archival policy includes at least one of:

an owner identity,

payload information,

archival period,

access mode to server,

user access rights,

logical file location in repository,

cryptographic details, or

payment model.

66. A computer program product as claimed in claim 64, further including an export means to enable a user to access and/or retrieve said archival document or said digital information.

67. A computer program product as claimed in claim 64, wherein a person inputs said digital information to said receive means, and, following said formatting by said processing means, a response is returned to said person.

68. A computer program product as claimed in claim 64, wherein said data includes time stamp information and/or revocation information, and is bound with said digital information in said database.

69. A computer program product as claimed in claim 64, wherein said at least one external source belongs to a trusted third party, and said communication means determines what digital information requires certification and/or validation, and then communicates with the relevant database and/or server.
