Bill identification method and equipment based on two-dimensional code

Abstract

The invention relates to the field of data identification, in particular to a two-dimensional code technology. The invention provides a bill identification method based on the two-dimensional code, which comprises the following steps: Step 1: obtaining encrypted data of the two-dimensional code; Step 2: decrypting the encrypted data to obtain bill data; Step 3: searching matching information corresponding to a first encrypted signature in the identification equipment based on a second encrypted signature in the encrypted data; Step 4: and integrating the matching information and the bill dataand presenting the bill data. The invention solves the problem of anti-counterfeiting environmental adaptability and reduces the data hidden danger and the data maintenance cost. According to the two-dimensional code bill, information is directly put into the bill through the expansion of the data storage capacity, the mode of obtaining the information in the two-dimensional code through off-lineanalysis is realized, the effect of anti-counterfeiting verification is achieved, dependence on a regional network is avoided, the requirement on the environment is lower, database maintenance is notneeded, the cost is low, and the safety is high.

Description

technical field [0001] The invention relates to the field of software methods, in particular to two-dimensional code technology. Background technique [0002] Two-dimensional codes are widely used, especially in high-tech industries, storage and transportation industries, wholesale and retail industries, and other industries that need to quickly label information on items. Prior art one is the Chinese patent application whose patent publication number is CN105235410A, and its technical scheme is as follows figure 1 As shown, it discloses a bill with a two-dimensional code and its interactive system and method. In terms of anti-counterfeiting, the invention needs to rely on physical properties such as anti-counterfeiting paper, and the cost of use is relatively high; the two-dimensional code icon in the invention is labeled with a double-layer structure, which is difficult to operate and the process is too cumbersome; the invention needs to rely on The network performs anti...

Problems solved by technology

This method is expensive to use, and it is prone to damage or loss during use, which is not conducive to the use in real scenarios; before generating the QR code, it is necessary to read the smart card information through a card reader, which limits the Code ticket generation, although safe, is not a humanized process
