摘要

An anti-counterfeiting feature generation method for a valuable document and an authentication method and 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 document by facilitating machine recognition, thereby improving the authentication accuracy of the financial self-service equipment to the valuable document.
