Abstract

The invention discloses a two-dimensional code generation method and device and a two-dimensional code recognition method and device. The two-dimensional code generation method comprises the steps that a first server sends a request for generating a two-dimensional code to a second server, wherein the request comprises information used for generating a two-dimensional code, and the second server performs digital signing on the information used for generating a two-dimensional code according to the received request for generating a two-dimensional code; two-dimensional code information containing a digital signature is sent to the first server; and the first server generates a two-dimensional code by using the two-dimensional code information. According to the embodiment of the invention, a two-dimensional code is generated through a cooperative effect between one server and another server, the safety and the effectiveness of the two-dimensional code are enhanced, and whether the two-dimensional code is tampered or not is facilitated to be recognized in the two-dimensional code recognition process.

Description

technical field [0001] The present application relates to the technical field of graphics and images, and in particular to a two-dimensional code generation method and its equipment, and a two-dimensional code recognition method and its equipment. Background technique [0002] Two-dimensional code, also known as two-dimensional barcode, records data symbol information through a bar / space pattern formed by a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules. The two-dimensional code has the characteristics of large information capacity, wide coding range, strong fault tolerance, high decoding reliability, etc., and also has the advantages of low cost and easy production. Therefore, two-dimensional codes are widely used in people's lives. [0003] With the development of the Internet and the popularity of mobile terminals, QR codes can be seen everywhere in life. For example, merchants can post payment QR codes at the pay...
