Methods and tangible objects employing textured machine readable data
First Claim
1. A substantially three-dimensional article having the exterior thereof shaped to define a textured steganographic pattern, the pattern encoding a plural-bit data payload, the existence of said data payload not being evident to a human viewer of the article, but the plural bits of payload data being detectable by computer processing of visible light scan data corresponding to said textured steganographic pattern, the data payload including date data.

Abstract
A tangible object (such as a microprocessor, wristwatch, pharmaceutical, compact disc, vehicle part, etc) is surface-textured to encode a plural-bit code thereon. In one arrangement, this encoding conveys date information. In use, the object can be imaged by a scanner apparatus, and the resulting scan data analyzed to discern the plural-bit code. The decoded date information can be used in a determination relating to the object. For example, at a port of entry, date information encoded on a Rolex wristwatch can be used to determine whether importation of the wristwatch should be permitted. The texture-encoded data can also convey other information, such as a vehicle identifier for an automotive part, a place of fabrication, a specification with which the part complies, etc.

6. A method of processing a substantially three-dimensional physical object having a plural-bit code steganographically encoded thereon, the encoding taking the form of texturing that shapes the exterior of said object, the method comprising:
-
acquiring visible light scan data corresponding to at least a portion of said shaped exterior;
discerning the plural-bit code from said scan data;
by reference to said plural-bit code, determining date information; and
at least in part by reference to said determined date information, determining if a transaction involving the object should be refused. - View Dependent Claims (7)
