In some embodiments, the information identifier sent by the server may be received, and in the process of generating the picture code from the information identifier, when the picture code is a two-dimensional code, processing procedures such as encoding, error correction, and the like may be performed on the information identifier. Specifically, the information identifier may be encoded to obtain a data codeword, where the data codeword may be a codeword composed of binary digits, that is, the data codeword may be a codeword composed of 0 and 1. In the process of encoding the information identifier, if the information identifier comprises one or more of the functional symbols such as numbers, letters, punctuations and the like, after the symbols are encoded, an ending symbol or a supplementary symbol can be added to the encoding structure to obtain a data codeword, and standard encoded data can be obtained so as to facilitate the subsequent codeword processing process. Further, error correction may be performed on the data codeword to obtain a target codeword. In the process of correcting the data code words, the data code words can be grouped to obtain different blocks, each block can comprise a plurality of bytes of code words, the error correction code words corresponding to each block can be generated according to an error correction algorithm, and then the data code words and the error correction code words can be alternatively placed to obtain target code words.
