COUNTERFEIT DETERRENCE SYSTEM

摘要

Processing of banknote- or other security document-images in a computer system is sensed, and serves to launch (or direct) a web browser to a web site that educates the user about limitations on use of such imagery, and/or provides substitute imagery that may be utilized for legitimate purposes. Such images may be recognized by a digital watermark encoded therein or by other known techniques. The technology is applicable to a wide class of documents that should not be duplicated, including passports, visas, postal stamps, stock certificates, travelers checks, concert/event tickets, lottery tickets, etc. The technology may also be used for non-security applications, e.g., recognizing images, video, or audio being processed on a user's computer as belonging to a certain class, and presenting the user with a web page relating to that class of object. Commerce opportunities may thereby be made available to the user.
