10. The system of claim 1, wherein the at least one item printing station is operable by a third party to print an imprint on an item for use by a user.

11. The system of claim 1, wherein the security parameter includes a time frame code, whereby the indicium is authenticated only when presented within a predefined time period.

12. The system of claim 1, wherein the security parameter includes an assigned location code, whereby the indicium is authenticated only when presented at one or more predefined item presentation stations.

13. The system of claim 1, wherein the items comprise documents.

14. The system of claim 13, wherein the documents embody monetary value.

15. The system of claim 13, wherein the documents comprise evidentiary documents.

16. A method of authenticating items, the method, for each item, comprising the steps of:

generating a transaction data stream for an indicium to be applied to an item as an imprint, the indicium including a cryptographically-encoded component;

printing the imprint on an item;

receiving data relating to the indicium;

authenticating the indicium;

comparing the data related to the indicium to stored data related to a previously authenticated indicium and, if the comparison indicates a dupliate, determining the indicium to be invalid; and

providing an authentication message to the item presentation station in dependence upon whether the indicium is determined to be valid or invalid,

wherein the indicium comprises at least one security parameter which is not provided in human-readable form in the imprint.

17. The method of claim 16, wherein the indicium comprises a barcode.

18. The method of claim 17, wherein the indicium comprises a two-dimensional barcode.

19. The method of claim 16, wherein the cryptographically-encoded component is encoded by digital signature.

20. The method of claim 16, wherein the cryptographically-encoded component is encoded by encryption.

21. The method of claim 16, wherein the cryptographically-encoded component is encoded by encryption and digital signature.

22. The method of claim 16, wherein the printing step is performed at the request of a user.

23. The method of claim 22, wherein the transaction data generating step is performed at the request of the user.

24. The method of claim 22, wherein the transaction data generating step is performed at the request of a third party on behalf of the user.

25. The method of claim 16, wherein the printing step is performed at the request of a third party to print the imprint on an item for use by a user.

26. The method of claim 16, wherein the security parameter includes a time frame code, whereby the indicium is authenticated only when presented within a predefined time period.

27. The method of claim 16, wherein the security parameter includes an assigned location code, whereby the indicium is authenticated only when presented at one or more predefined item presentation stations.

28. The method of claim 16, wherein the items comprise documents.

29. The method of claim 28, wherein the documents embody monetary value.

30. The method of claim 28, wherein the documents comprise evidentiary documents.

31. The method of claim 16, further comprising decrypting the data relating to the indicium using a public key of the presentation station, wherein the data relating to the indicium is encrypted with a private key of the presentation station.

32. The method of claim 31, further comprising receiving a new public key from the processing unit, wherein a new public-private key pair is generated by the presentation station following each authentication transaction.

33. The method of claim 16, wherein the security parameter includes a Personal Identification Number (PIN) and an assigned merchant code, whereby the indicium is authenticated only when presented at one or more predefined merchants.

34. The method of claim 16, wherein a user separately provides the PIN at the item presentation station and the indicium is determined to be valid only if the separately provided PIN matches the PIN included in the indicium.
