Claim Text:
1. A method for coding and decoding three-dimensional code of a content to be displayed on a screen, comprising the steps executed by a computer of: (a.1) acquiring an initial string A (a.2) adding a time information in said string A (a.3) generating a two-dimensional code of said content; (a.4) recalling step (a.1), step (a.2), and step (a.3) generating the next said two-dimensional code in the next time unit, wherein said time unit is a constant or variable time interval T; (a.5) generating said two-dimensional code continuously forming a continuous code flow of a three-dimensional code of said content; and (b.1) capturing said continuous code flow of said three-dimensional code through an identifier of two-dimensional codes acquiring a fragment of said three-dimensional code, wherein said fragment of said three-dimensional code comprises at least one frame of said two-dimensional code that displays on the screen of said identifier.
