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...

Description

technical field [0001] The invention relates to the technical field of two-dimensional code information security, in particular to an embedded double two-dimensional code information security method. Background technique [0002] Two-dimensional code technology was born in the late 1980s. With the development of technology, a variety of code systems have been developed in the research of two-dimensional code symbol representation technology, among which QR code has been the most widely used in recent years (two-dimensional code described in this paper QR code refers specifically to QR code), which can be seen everywhere in the streets and alleys. QR code has many advantages, the most important of which is that it has strong coding ability, can express rich information, and is scalable. At the same time, it also has strong error correction ability and fast response characteristics, which is very convenient to use. This laid the foundation for its widespread use. [0003] Ho...
