Embodiment
[0030] A method for confidentiality of embedded double two-dimensional code information, including a code scanning client, a large two-dimensional code, and a small two-dimensional code, the large two-dimensional code is used to carry the text content to be released, and the text content is T, the small two-dimensional code is used to carry verification information, and the verification information is P, which also includes the following steps:
[0031] Such as figure 1 As shown, A, encoding and encryption:
[0032] A1. Determine the error correction level and version number of the large two-dimensional code according to the size of the text content T, and determine the error correction level and version number of the small two-dimensional code according to the size of the verification information P, and the text content T and verification information P can be fully encoded;
[0033] A2. Set an encryption password, the encryption password is K, and mix the encryption passwor...
