The invention provides a two-dimensional code color encryption method and device. The two-dimensional code color encryption method includes the following steps that: the two-dimensional code color encryption device allocates coordinates for a plurality of matrix points to be encrypted of a two-dimensional code image to be encrypted; whether the plurality of matrix points to be encrypted are black points is judged sequentially; and when it is judged that the matrix points to be encrypted are black points, the color of the matrix points to be encrypted which are the black points is replaced with a preset encryption color according to a preset color mapping relation table and the coordinates of the matrix points to be encrypted which are the black points. According to the method and device of the invention, color encryption is performed on the two-dimensional code, and therefore, when scanning the two-dimensional code which has been subjected to color encryption, a user needs to use a corresponding decryption program to obtain information carried by the two-dimensional code, and therefore, the security of the information carried by the two-dimensional code can be improved, and thus, the problem of low security of two-dimensional code information which is caused by a situation that information carried by existing two-dimensional codes can be scanned by any one scanning terminal so as to be obtained can be solved.
Description
technical field [0001] The invention relates to a two-dimensional code color encryption method and device. Background technique [0002] Two-dimensional codes record data symbol information with black and white graphics that are distributed on a plane (two-dimensional direction) according to a certain rule with a certain geometric figure; cleverly use the "0" that constitutes the internal logic basis of the computer in the code compilation , The concept of "1" bit stream, using several geometric shapes corresponding to binary to represent text and numerical information, automatically read through image input equipment or photoelectric scanning equipment to realize automatic processing of information: it has some common features of barcode technology : Each code system has its specific character set; each character occupies a certain width; it has certain verification functions, etc. However, the information carried by the existing two-dimensional code is relatively simple, ...
