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.
