Method for identifying cigarette authenticity based on self-encrypted self-checking two-dimensional code

Disclosed in the invention is a method for identifying cigarette authenticity based on a self-encrypted self-checking two-dimensional code. A generation unit of a two-dimensional management unit generates a self-increasing serial number to generate a unique two-dimensional code; a printing unit prints the two-dimensional code at a designated position of a box skin package; a producing unit uses the box skin printed with the two-dimensional code to carry out cigarette packaging and uses a scanning device to scan a cigarette after primary packaging, the two-dimensional code that has been applied to production is recorded and is submitted to an activation unit (12) of a two-dimensional code management unit (1) to carry out activation processing; a user uses a scanning unit to scan the two-dimensional code printed at the internal package; an identification unit of the two-dimensional code management unit carries out decoding to obtain a serial number; and the identification unit of the two-dimensional code management unit carries out cigarette authenticity judgment according to the activation state of the serial number and the number of times of submission. According to the invention, a unique self-encrypted self-checking two-dimensional code is printed at each package of cigarettes, so that a consumer can use an intelligent terminal to scan the unique two-dimensional code at each package of cigarettes, thereby obtaining cigarette authenticity information simply, conveniently, and rapidly.
