Abstract

The invention relates to the field of information security authentication, in particular to an identification method and identification system for anti-counterfeiting information of a certificate, andthe identification method comprises the steps: obtaining a certificate image containing the anti-counterfeiting information; correcting and segmenting the certificate image to obtain a plurality of anti-counterfeiting areas, identifying the plurality of anti-counterfeiting areas respectively, and outputting identification results corresponding to the anti-counterfeiting areas in sequence; and judging the authenticity of the certificate image in combination with the identification result corresponding to each anti-counterfeiting area. The identification method has the advantages that the detection of the anti-counterfeiting information is comprehensive, the anti-counterfeiting detection of various certificates can be covered, the efficiency and the accuracy are higher compared with the traditional mode, and the safety is integrally improved.

Description

【Technical field】

[0001] The invention relates to the field of information security certification, in particular to a method and system for identifying anti-counterfeiting information of certificates. 【Background technique】

[0002] As a medium for storing and authenticating personal information, there are many types of documents, including passports, ID cards, Hong Kong and Macau passes, etc. The anti-counterfeiting information identification of its multispectral images is widely used in customs, airports, railway stations, security checkpoints and other scenarios. In recent years, China's international exchanges have been increasing, which has brought great challenges to departments that need to identify the authenticity of documents; the variety of types of documents and the different identification points of various documents make it more difficult to identify anti-counterfeiting information on document images. At present, in China, manual and machine methods are general...
