1. A method of preparing an article for later verification, the method comprising:
- generating a biometric type signature for an article from analysis of intrinsic surface or internal structure thereof;
combining the biometric type signature for the article with an identifier code for the article; and
applying the combined code to a part of the article from which the biometric type signature was generated.

Abstract
There can be provided a complete and flexible multi-tier article authentication system. A number of implementation options are possible, and in one of which an article can include an applied code thereon, which applied code includes an identifier code for the article and a biometric type signature for the article, the biometric type signature having been generated from analysis of intrinsic surface or internal structure of a part of an article to which the applied code is applied.

10. A method of validating the authenticity of an article, the method comprising:
-
reading an assigned code from an article; extracting from the assigned code an identifier for the article; extracting from the assigned code a biometric type signature for the article; using the identifier as a first authentication method to determine the authenticity of the article by comparing the extracted identifier to a record of one or more valid identifiers; and using the biometric type signature as a second authentication method to determine the authenticity of the article by comparing the extracted biometric type signature to a biometric type signature generated from analysis of intrinsic surface or internal structure of an area of the article from where the applied code is read. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. Apparatus for preparing an article for later verification, the apparatus comprising:
-
a scanning unit operable to scan an article to perform analysis of intrinsic surface or internal structure thereof a processing unit operable to generate a biometric type signature for an article from data gathered by the scanning unit; a processing unit operable to combine the biometric type signature for the article with an identifier code for the article; and a printing unit operable to apply the combined code to a part of the article scanned by the scanning unit. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)

31. Apparatus for validating the authenticity of an article, the apparatus comprising:
-
a reading unit operable to reading an assigned code from an article; a processing unit operable to extract from the assigned code an identifier for the article and a biometric type signature for the article; a comparison unit operable to use the identifier as a first authentication method to determine the authenticity of the article by comparing the extracted identifier to a record of one or more valid identifiers; and a comparison unit operable to use the biometric type signature as a second authentication method to determine the authenticity of the article by comparing the extracted biometric type signature to a biometric type signature generated from analysis of intrinsic surface or internal structure of an area of the article from where the applied code is read. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

- 44. An article comprising an applied code thereon, which applied code includes an identifier code for the article and a biometric type signature for the article, the biometric type signature having been generated from analysis of intrinsic surface or internal structure of a part of an article to which the applied code is applied.
