ANTI COUNTERFEITING FEATURE GENERATION METHOD FOR VALUABLE DOCUMENT AND AUTHENTICATION METHOD AND DEVICE THEREFOR

摘要

An anti counterfeiting feature generation method for a valuable document and an authentication method a nd device therefor. The anti counterfeiting feature generation method for a valuable document uses the anti counterfeiting feature information redundancy to hide accurate information about an anti counterfeiting feature. In the generation method the anti counterfeiting feature of a valuable document has little change on the human perception but a valuable document authentication device in a financial self service equipment can effectively extract the hidden accurate information about an anti counterfeiting feature from signals obtained by a sensor and conduct quantitative detection and authentication thereby effectively authenticating whether the valuable document is counterfeit or not. A new anti counterfeiting feature which facilitates machine recognition is loaded to the valuable document and a corresponding valuable document authentication device is configured to a financial self service equipment so that the financial self service equipment can read the anti counterfeiting feature of the valuable documen t by facilitating machine recognition thereby improving the authentication accuracy of the financial self service equipment to the valuable document.
