Abstract

A method and apparatus of communicating information comprising providing a datum which includes a digital certificate containing data. The digital certificate including an extension which includes: a first identifier which specifies a major classification of the data; a second identifier which specifies a minor classification of the data; and data in a format according to the major classification and the minor classification, the data indicating an owner of the datum and a use for which the datum is intended. The certificate allows authentication of the certificate itself and the data contained therein, and the data contained in the certificate can include information allowing verification of the identity of the holder of the certificate.

Claims

1. A multimedia digital certificate system comprising:

a. a first circuit to create a digital certificate; and

b. a second circuit to extend the digital certificate to include an extension, the extension includes a first field for multimedia data and a second field for information to identify a type of the multimedia data contained in the first field.

2. The system of claim 1 wherein the extension of the digital certificate further includes a third field being a criticality flag to signal a recipient of the digital certificate that an authentication process at the recipient has failed when the recipient is unable to read the extension.

3. The system of claim 1 wherein the recipient of the digital certificate includes an application remotely located from the first circuit and the second circuit.

4. The system of claim 1 wherein said second field including a major type field to indicate a basic use of the digital certificate and a minor type field to indicate an exact type of the multimedia data contained in the digital certificate.

5. The system of claim 1 wherein the multimedia data includes a logo.

6. The system of claim 1 wherein the multimedia data includes a digitized handwritten signature.

7. The system of claim 1 wherein multimedia data includes a picture.

8. The system of claim 1 wherein the multimedia data includes audio.

9. The system of claim 1 wherein the multimedia data includes video.

10. The system of claim 1 wherein the multimedia data includes biometric information.

11. The system of claim 10 wherein the biometric information includes a fingerprint.

12. The system of claim 10, wherein the biometric information includes a footprint.

13. The system of claim 10, wherein the biometric information includes a geometry of a hand.

14. The system of claim 10, wherein the biometric information includes a retinal scan.

15. The system of claim 10, wherein the biometric information includes a voice print.

16. The system of claim 10, wherein the biometric information includes a dynamic signature.

17. A medium for storing data for access by a software routine being executed on a transaction system, comprising:

a data structure stored on the medium, the data structure being a digital certificate having an extension including a first field for multimedia data and a second field for information to identify a type of the multimedia data contained in the first field.

18. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a logo.

19. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a digitized handwritten signature.

20. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a digitized picture.

21. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes an audio clip.

22. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a video clip.

23. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a fingerprint.

24. The medium of claim 17 comprising one of a magnetic tape and a disk drive.

25. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a geometry of the hand.

26. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a retinal scan.

27. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a voice print.

28. The medium of claim 17, wherein the multimedia data of the stored digital certificate includes a dynamic signature.

29. A method comprising:

creating a digital certificate; and

extending said digital certificate to include an extension, said extension includes a first field for multimedia data and a second field for information to identify an extension type indicated by the multimedia data contained in the first field.

30. The method of claim 29, wherein said multimedia data includes 2 identification information.

31. The method of claim 29, wherein said multimedia data includes a logo.

32. The method of claim 29, wherein said multimedia data includes a digital signature.

33. The method of claim 29, wherein said multimedia data includes a digitized picture.

34. The method of claim 29, wherein said multimedia data includes sound.

35. The method of claim 29, wherein said multimedia data includes video.

36. The method of claim 29, wherein said multimedia data includes biometric information.

37. The method of claim 36, wherein said biometric information includes a fingerprint.

38. An apparatus comprising:

a card; and

a memory associated with the card, the memory includes a digital certificate having an extension including a first field for multimedia data and a second field for information to identify an extension type defined by the multimedia data contained in the first field.

39. The apparatus of claim 38, wherein the memory includes a magnetic media.

40. The apparatus of claim 38, wherein the card is an identification card.

41. The apparatus of claim 38, wherein the card is a credit card.

42. The apparatus of claim 40, wherein the identification card includes one of a driver'"'"'s license, a birth certificate, a social security card, a library card, a frequent flier card, a passport, a corporate identification badge, a building access card, a medical insurance card and a prescription card.

43. The apparatus of claim 38, wherein the multimedia data includes one of biometric information.
