Abstract:
The present invention provides a method and apparatus for the production and labeling of objects in a manner suitable for the prevention and detection of counterfeiting. Thus, the system incorporates a variety of features that make unauthorized reproduction difficult. In addition, the present invention provides a system and method for providing a dynamically reconfigurable watermark, and the use of the watermark to encode a stochastically variable property of the carrier medium for self-authentication purposes.
