Printed image information embedding and identifying method enabling public to read and identify code information easily through mobile phone

Abstract

The invention provides a printed image information embedding and identifying method enabling the public to read and identify code information easily through a mobile phone, comprising a data reading step, an information embedding step, and a printed image output step. In the data reading step, data to be embedded and an object image for information embedding are read from a memory. In the information embedding step, the read data to be embedded is embedded into the object image for information embedding by using an invisible code which is generated by a difference adjusting method of the image state in different positions or a dot-matrix hiding method. In the printed image output step, the image embedded with the information is output, and a printed image embedded with the information is generated. By using the method, the public can identify the identifier of a commodity through a mobile phone based on the principle of one code for one label. An ID can be given to each commodity, so that commodities can be traced, and the network entry problem of commodities and the big data processing problem of commodity circulation can be solved.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for embedding and identifying printed image information suitable for mobile phone public reading. Background technique [0002] In recent years, food safety issues have attracted more and more attention from the society and the government. Counterfeit goods and other phenomena have become important social issues that endanger people's health, shake social stability and affect the consolidation of the regime. Although the government has stepped up efforts to implement a large number of government supervision measures , however, has not been able to be effectively contained. [0003] The social problem of eradicating counterfeit goods depends on the public to solve. For this reason, technology that supports the public to read authenticity has attracted much attention today. [0004] The traditional method of using the mark formed by the diffraction of light to realiz...

Problems solved by technology

As the vast majority of mobile phones currently do not have MFC chips, the identification of RFID code content cannot be realized through mobile phones, so that it is difficult for mass mobile phones to identify the authenticity of goods, and the high cost of RFID has always hindered the popularization of this technology.

[0016] The above-mentioned patent document 4 proposes to use digital watermarking technology to realize the information hiding of the code, but the area of ​​the code is too large, and it will have a great impact on the image after being buried in the printed image. The image data is not suitable for mass production printing of logos
