The present invention provides a two-dimensional code color encryption method and device. The two-dimensional code color encryption method includes: the two-dimensional code color encryption device assigns coordinates to a plurality of matrix points to be encrypted in the two-dimensional code image to be encrypted ; Judging whether the plurality of matrix points to be encrypted are black dots in turn; when judging that the matrix points to be encrypted are black dots, according to the preset color mapping table and the coordinates of the matrix points to be encrypted as black dots , replacing the color of the matrix point to be encrypted which is a black point with the preset encryption color. This method encrypts the color of the two-dimensional code, so that when the user scans the color-encrypted two-dimensional code, he needs to go through the corresponding decryption program to obtain the information carried by the two-dimensional code, which greatly improves the user experience. The security of the information carried by the two-dimensional code is improved, so that the information carried by the existing two-dimensional code can be obtained after being scanned by any scanning terminal, resulting in the problem that the information security of the existing two-dimensional code is not high.
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, ...
