The embodiment of the invention discloses a verification method and device for electronic certificate information, and relates to the technical field of information security. The method comprises the steps that a digital color image and a digital grayscale image corresponding to the digital color image are generated; the digital color image and the digital grayscale image are respectively segmented into a plurality of blocks; an anti-counterfeiting identification insertion location is marked in a bit in first transparency channel values of all the blocks of the digital color image; a bit value corresponding to the anti-counterfeiting identification insertion location is replaced by an anti-counterfeiting mark value to form a second transparency channel value, and then an electronic certificate image is generated. If the electronic certificate image to be detected is detected, the anti-counterfeiting identification is extracted from the electronic certificate image to be detected, and a digital verification code and a binary image verification code are obtained according to the anti-counterfeiting identification and are verified respectively. The verification method and device for the electronic certificate information can solve the problems that in the current electronic certificate technology, the electronic certificate information can be easily counterfeited, the anti-counterfeiting capacity is low, and automatic verification cannot be achieved.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a method and device for verifying electronic credential information. Background technique [0002] At present, with the popularization of the Internet and the development of computer technology, electronic voucher technology has been widely used in the banking industry. At present, electronic voucher technology generally includes electronic document system and electronic note system designed for bank notes. [0003] The electronic document system mainly replaces the use of traditional bank paper documents to a certain extent by generating electronic copies of bank paper documents. In order to meet the verification requirements of bank users for documents, banks generally need to set up special verification channels for such issued electronic documents. After the user enters information such as the serial number and verification code of the document, the bank can re...
