Abstract
A method, apparatus, and computer readable medium are provided. The method includes receiving, from a terminal, target information to be coded in a graphic identification code, and personalized effect information. First lattice data is generated according to the target information. Each data point in the first lattice data is processed according to first-type effect information included in the personalized effect information, to obtain second lattice data. The second lattice data is processed according to second-type effect information included in the personalized effect information, to obtain the graphic identification code.
