specific Embodiment

[0042] The scanning unit runs on the consumer query terminal, the manufacturer's production line terminal, the logistics terminal and the intermediary terminal. The scanning unit has the function of image self-correction. The correction process includes the following steps:

[0043] a. When the scanning unit scans the digital identity authentication image, it takes multiple digital identity authentication images and corrects them into square images of the same size;

[0044] b. Enhance and filter the square image in a, then perform binarization and region marking, and use the standard checkerboard image calibration method to correct the black and white squares of the square image;

[0045] c. Coordinate the square image in b with the maximum resolution to form a grid, and calibrate the color of each small block in the grid. The principle of calibration is based on the number of times black or white appears at the same position in the image, taking into account the color of adja...

Abstract

The invention discloses a security traceability management system. The security traceability management system particularly comprises a scanning unit, a digital identity management database unit and a remote server unit, wherein the scanning unit sends a first query command to the remote server unit; the remote server unit receives the first query command and then returns the manufacturer server address and the verification public key to the scanning unit; the scanning unit receives the manufacturer server address and the verification public key, and sends a second query command to the digital identity management database unit; the digital identity management database unit receives the second command and returns complete information of a product to the scanning unit according to the manufacturer server address. The system manages at each stage of product circulation, can effectively prevent product counterfeit and repeated offering, is simple and convenient in management process, and is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to the design of an anti-counterfeiting traceability management system. Background technique [0002] Enterprises have a clear demand for refined management of products, especially well-known products and best-selling products for anti-counterfeiting and traceability. How to develop a low-cost, easy-to-use anti-counterfeiting technology and product ID card production technology is a persistent industry. the goal that is pursued. Current product anti-counterfeiting technologies, such as laser labeling, color printing labels, watermarks, digital scratch codes, and telephone inquiries, all have problems such as inconvenient use, high cost, diminishing effect, and difficulty in popularization. The new generation of product digital identity authentication The technology has the advantages of convenient production and various carriers, but it needs to solve the pr...
