PROBLEM TO BE SOLVED: To provide a two-dimensional code having a redundant structure in an area where data is embedded, a two-dimensional code generation method for generating the two-dimensional code, a two-dimensional code generation device, a program, and a recording medium.SOLUTION: In a two-dimensional code constituted by a model number, a mask pattern, an error correction level, embedded data (a data code word) and a filler code word (and further an error correction word), secret information is embedded as metadata into a plurality of segments constituting the data code word, and by constitution positions of the segments, several module patterns can be generated. |
