A high-speed device and decoding method for safe decoding of two-dimensional codes of vehicle qualification certificates

Abstract

The invention provides a high-speed document scanner capable of safely decoding a two-dimensional code of a vehicle approval certificate. A U-type shield security module is inserted or embedded in the high-speed document scanner. The high-speed document scanner is used for collecting a two-dimensional code image. The U-type shield security module is used for converting ciphertext information into plaintext information. A decoding method includes the steps that (a) the high-speed document scanner is connected with a PC, and the U-type shield security module is connected with the high-speed document scanner; (b) the high-speed document scanner judges whether a U-type shield is legal by verifying the correctness of authentication data; (c) the high-speed document scanner collects the two-dimensional code image and obtains a decodable image through an image processing method; (d) the high-speed document scanner conducts decoding to obtain ciphertext binary data of the two-dimensional code; (e) the high-speed document scanner sends a two-dimensional code ciphertext to the U-type shield, and the U-type shield obtains the plaintext information of the two-dimensional code through a decryption algorithm. According to the high-speed document scanner and the decoding method, decoding of the two-dimensional code is conducted in the U-type shield, so that the security of the decryption algorithm and a decryption key is ensured, scanning equipment is not needed, the process is simplified, the data entry efficiency is improved, and expenses for purchasing the scanning equipment are omitted.

Description

technical field [0001] The present invention relates to a high-definition image of the two-dimensional code of the vehicle certificate collected by the high-speed camera and a decoding method thereof, and more specifically, to a high-definition image of the two-dimensional code of the vehicle certificate collected by the high-speed camera and passed through the U-shield security module. A high-speed camera for obtaining plaintext information of a two-dimensional code and a decoding method. Background technique [0002] With the introduction of the new version of the certificate, vehicle management offices in various places can collect vehicle data by directly reading the two-dimensional barcode on the certificate when registering a new car, solving the problems of slow manual entry and error-prone, thereby improving the quality of vehicles in the vehicle management offices. Efficiency and accuracy of registration. The Traffic Management Science Research Institute of the Min...
