Abstract

Systems and methods are disclosed for authenticating electronic messages. A data structure is generated by a computer server which allows for the authentication of the contents and computer server identity of a received electronic message and provides a trusted stamp to authenticate when the message was sent. Data which can authenticate the message, the computer server identity, and the time the message was sent is included into a data structure which is called an Electronic PostMark (EPM).

Claims

1-31. -31. (canceled)

32. A computer-implemented method for authenticating an electronic message, comprising:

receiving, by an authentication server at a predetermined time, a request to authenticate the electronic message and a hash value derived from the electronic message;

generating an electronic postmark data structure, the electronic postmark data structure comprising at least one of;

the hash value;

time and date information;

branding data from a system registry; and

a digital signature generated for the electronic postmark data structure;

storing a copy of the the electronic postmark data structure in a log file; and

sending the electronic postmark data structure to a recipient client.

33. The method of claim 32, further comprising:

generating an authorized digital key for the electronic postmark data structure, wherein a recipient can use the authorized digital key to verify the electronic postmark data structure; and

sending the digital key to the recipient client.

34. The method of claim 32, further comprising:

generating a public digital key for a recipient; and

exporting the public digital key to a key authenticator.

35. The method of claim 34 wherein the step of exporting the public digital key to a key authenticator includes using a key authenticator which is one of a key signing authority or a certificate authority.

36. The method of claim 32, further comprising the step of:

receiving updates to the time and date information.

37. The method of claim 32, wherein the branding data is from a Windows NT®

system registry.

38. The method of claim 32, further comprising:

interfacing with the system registry via a configuration manager graphical user interface.

40. The method of claim 32, wherein receiving a request to authenticate the electronic message includes receiving the electronic message.

41. The method of claim 32, wherein sending the electronic postmark data structure to a recipient client includes sending the electronic message.

46. The method of claim 32, further comprising:

creating a digest of the log file.

39. (canceled)

42-45. -45. (canceled)

47. A system for authenticating an electronic message, comprising:

a receiver that receives, at a predetermined time, a request to authenticate the electronic message and a hash value;

a temporal component that obtains time and date information;

a branding component that receives branding data from a system registry;

a signature component that generates a digital signature;

a generating component that generates an electronic postmark data structure comprising at least one of;

the hash value;

time and date information;

branding data from a system registry; and

a digital signature generated for the electronic postmark data structure;

a database that stores a copy of the electronic postmark data structure in a log file; and

a sender that sends the electronic postmark data structure to a recipient client.

48. The system of claim 47, further comprising:

a key generating component that generates an authorized digital key for the electronic postmark data structure, wherein a recipient can use the authorized digital key to verify the electronic postmark data structure, and wherein the sender sends the digital key to the recipient client.

49. The system of claim 47, further comprising:

a public key generating component that generates a public digital key for a recipient; and

an exporting component that exports the public digital key to a key authenticator.

50. The system of claim 49, wherein the exporting component exports the public digital key to a key authenticator which is one of a key signing authority or a certificate authority.

51. The system of claim 47, wherein the temporal component receives updates to the time and date information.

52. The system of claim 47, wherein the branding data is from a Windows NT®

system registry.

53. The system of claim 47, further comprising:

an interfacing component that interfaces with the system registry via a configuration manager graphical user interface.

54. The system of claim 47, wherein the receiver receives the electronic message.

55. The system of claim 47, wherein the sender sends the electronic message.

56. The system of claim 47, further comprising:

a digest component that creates a digest of the log file.
