In the field of information processing, the invention is related to a mobile phone information embedding code generation method, information embedding method, and reading method for same. The invention is characterized by enabling distinguishing of product authenticity under natural light and using a standard mobile phone, and solves the problem of unifying authenticity identification for a general consumer and authenticity identification of an expert. A mobile phone information embedding code is configured from a dot pattern enabling multibit information to be written on the basis of the geometric placement or physical placement of an information dot relative to a specified reference dot. Said information embedding code configures at least one type of dot pattern capable of writing scan-prohibited information, said dot pattern containing an ink such as thermal ink, sun-sensitive color-changing ink or OVI (optically variable) ink. On the basis of a new type of vertically-horizontally integrated virtual reference line submitted by the invention, by means of a different position distribution of an information dot matrix or by means of the distribution of a phase modulation result, a new type of dot matrix pattern that enables recording of multiple-bit information maximally records multiple-bit information and is capable of increasing the efficiency of code information recording. |
