A two-dimensional code generation method and apparatus, a two-dimensional code identification method and apparatus, an electronic device, and a storage medium are provided. The method includes generating a data codeword sequence according to input information, encrypting the data codeword sequence to generate an encrypted codeword sequence, determining a number of error correction blocks, and generating the two-dimensional code from the data codeword sequence and the encrypted codeword sequence according to a construction mode corresponding to the number of error correction blocks.

Two-dimensional code generation and identification

A two-dimensional code error correction decoding method is provided. In an embodiment, a two-dimensional code image is preprocessed to obtain a data codeword for decoding; optimal parameter matching is performed based on the data codeword to obtain a corresponding interpolation severity, and interpolation is performed based on the interpolation severity to construct a binary polynomial; an optimal information polynomial is obtained based on the binary polynomial, and the optimal information polynomial is used as an information codeword; and data decoding is performed based on the information codeword to obtain original information corresponding to the two-dimensional code image.
