Abstract

The invention discloses a card verification system and method based on a multi-dimensional code. The system includes a multi-dimensional code generating unit, a multi-dimensional code decoding and information verification unit; the multi-dimensional code generating unit is used to acquire user basic information and user biometric images, and Generate a multi-dimensional code; use a card with an RFID tag as a multi-dimensional code carrier; a multi-dimensional code decoding and information verification unit is used to collect and identify the multi-dimensional code information on the card, and perform information verification in combination with the RFID tag data and database data; The method is based on the system, through the decoding information of the multi-dimensional code image on the card, the storage information of the card RFID label and the storage information of the database to complete the multiple verification of the information; it solves the limited storage capacity of the existing two-dimensional barcode anti-counterfeiting and the information is easy to be tampered with issues; improved card identification and verification accuracy.

Description

technical field [0001] The invention belongs to the field of information authentication, and more specifically relates to a card verification system and method based on a multi-dimensional code. Background technique [0002] In recent years, with the advancement of science and technology and the acceleration of the process of global economic integration, counterfeiting has become increasingly rampant. Falsification not only destroys the market order, but even endangers the interests of the country and the people. Existing anti-counterfeiting technologies include laser anti-counterfeiting, fluorescent anti-counterfeiting, magnetic anti-counterfeiting, temperature-changing anti-counterfeiting, special plate-making printing, etc. Due to the high cost and limited anti-counterfeiting, the scope of use of these anti-counterfeiting technologies is limited, so establishing an effective and highly confidential anti-counterfeiting system has become an important research topic in the ...
