ABSTRACT:
Techniques for determining authenticity of analog forms such as packaging or documents (117). One of the techniques determines whether the analog form has been made directly from a digital representation (903) or by photocopying or scanning an analog form. The technique makes the determination by comparing (911) an original digital representation of a portion of the analog form with a digital recording (203) of the portion from the analog form and measuring differences in features that are affected by the operations of photocopying or scanning. The original digital representation (105) and the analog form may have a “noisy”, i.e., random or pseudo random pattern. Such noisy patterns may further be used for other authentication purposes, such as determining whether the portion of the analog form that has the noisy pattern has been altered and to carry hidden messages. The noisy pattern may carry a logo or may be part or all of a barcode.
