Patent US 9,508,032

A three-dimensional code is generated by adding a time dimension in a two-dimensional code so as to form the three-dimensional information structure, so that a three-dimensional code flow with time continuity is generated. The basic unit of the three-dimensional code flow is a two-dimensional code having time information. An encrypted three-dimensional code is able to represent multiple aspects of user behavior including time, place, location, instruction, operation device and etc. Through the three-dimensional code technique, the three-dimensional code content is implanted into a display scene of a client display screen. The user is able to interact with the display device through the three-dimensional code. Through the present invention, a screen without any interactive function can display the interactive media on the screen.
