Embodiment Construction

[0021] Such as figure 1 as shown, figure 1 The corresponding information that can be read from the QR code in

[0022] "http: / / www.iitdev.com", in the process of generating it, according to the QR code generation rules, convert its corresponding letters according to the following table, and add the identification code and terminator according to the rules, and finally generate Such as figure 1 The QR code shown. In the figure, 0 and 1 are used to represent figure 1 The black and white blocks in the middle QR code, 0 represents the white block, 1 represents the black block. Then the QR code can be represented by a data combination consisting of 0 and 1, such as 1111110100001000100000…..

Abstract

The invention provides a compressing and encrypting method for QR codes. The method comprises the steps that original QR codes are read to be binary information; bit shifting is conducted on the original information, and data are encapsulated; the space which exists after bit shifting is conducted on the original information is filled with identifiers with indicated compressed formats; the original information is sequentially stored into the space which exists after bit shifting is conducted on the next bit; the spaces of the extended last eight bits with the original information stored are supplemented to be zero, and the spaces of the last eight bits after next extension are filled with stop characters; the data operated in the above steps generate the QR code again. By means of the technical scheme, information stored in the QR code can be fast and conveniently compressed, and the corresponding encryption effect is achieved objectively.

Description

technical field [0001] The invention belongs to the field of computer graphic information, in particular to a compression and encryption method of a QR code. Background technique [0002] As we all know, after more than ten years of development, the one-dimensional barcode has become an effective means of information input in various industries starting from the commodity management represented by supermarkets and convenience stores. However, with the rapid development of informatization, some new demands Revealed: More information is stored, printed in a smaller space. [0003] With the rapid development of the network, on the surface, the information exchange and sharing between enterprises - the network infrastructure required for electronic data exchange has been established, but in fact, due to Internet protocol and security issues, it is still impossible to use the Internet for data exchange in the short term. exchange, thus requiring the use of QR codes for electroni...
