Document Type and Number:
WIPO Patent Application WO/2019/127514
Kind Code:
A1
Abstract:
A graphic code generation method and apparatus, a graphic code verification method and apparatus, a device, and a computer-readable storage medium. The generation method comprises: firstly acquiring a unique identifier (S101); binding the identifier to a byte to be encoded (S102); then generating a main body portion of a graphic code according to the bound byte to be encoded (S103); and using the identifier as a check portion of the graphic code to generate a complete graphic code (S104). Compared with existing graphic codes, the graphic code generated by means of the method has a check portion, so that a user such as a merchant can observe whether the check portion is changed so as to determine whether a graphic code such as a two-dimensional code has been tampered with or replaced. The method is intuitive and simple, and the problem of it not being easy to discover that an existing graphic code such as a two-dimensional code is tampered with or replaced is solved, and the use experience of a user is enhanced.
