Design Study of Two-Dimensional Anti-Counterfeiting Code Based on Moirés Mechanism

Abstract

Two dimensional code security system can be used to encrypt the user is decoded product, inspection by anti fake system or mobile phone software, can be genuine security information products. The Fourier transform of the amendment in the two-dimensional code patterns on the basis, transforming it into the function value is input to the server system. After a raster image processor (RIP) to draw the value of Bessel curve fitting, and tend to image in a plurality of sine function description, at the same time using the Visual Basic to draw a sinusoidal function diagram, the output image information two-dimensional code generation. Finally, through the internal matching storage printing output pattern and server security code information, you can verify the authenticity of products. It provides a simple and convenient method, and accurate for the commodity information traceability and product anti-counterfeiting identification.

Features and Applications of QR Codes

“…When a railway ticket is sold, the QR code anti-counterfeiting system will combine XSTL software to integrate and encrypt the information of the train number, price and destination ordered by the customer into a QR code and print it on the ticket [4]. When checking in, the ticket inspector only needs to scan the QR code on the ticket with the software identifying the QR code to determine the authenticity.…”

Design and Application of Quality Traceability System Based on Improved Production Process of Cigarette Packaging

“…Quality traceability technology and system have been widely used in manufacturing, logistics, and sales in developed countries [3][4][5]. Similarly, by the active efforts of relevant departments, we has also achieved good results in the application of quality traceability [5,6], especially highend liquor, organic vegetables, ecological meat, crop seeds, and other high value-added products [7,8].…”
