Problems solved by technology

[0003]However, the code value of the currently used offline graphic codes is generally longer. Correspondingly, in order to realize the identification of graphic codes, the requirements for scanning equipment High, for some older equipment, it may reduce the success rate of graphic code recognition or prolong the recognition time

Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0051] The idea of ​​the embodiment of this specification is that the offline graphic code is generated on the server side. Since the private key information of the institution (specifically referring to the graphic code issuing authority) is stored on the server, when the offline graphic code is generated on the server side, it can Directly use the priva...

Abstract

Embodiments of the invention provide an offline graphic code generation method and device. The offline graphic code generation method comprises the steps: receiving an offline graphic code acquisitionrequest sent by a graphic code display device; wherein the offline graphic code acquisition request carries identification information of a user corresponding to the graphic code display device; based on the configuration information of the offline graphic code of the user, generating a specified number of different random numbers according to a set random number generation rule; wherein the configuration information is used for indicating the number of the offline graphic codes needing to be generated, and the number of the random numbers is equal to the number of the offline graphic codes needing to be generated; and for each random number, performing signature processing on the random number and the user information corresponding to the identification information of the user, and taking the signature information obtained by the signature processing as a code value corresponding to the offline graphic code, the code value being used for generating the offline graphic code.

Description

technical field [0001] The present application relates to the technical field of graphic codes, in particular to a method and device for generating offline graphic codes. Background technique [0002] With the rapid development of information technology and the popularity of graphic code technology, graphic codes such as two-dimensional codes and barcodes have been widely used in various fields, such as payment fields, access control fields, and the like. In order to facilitate the use of users and reduce the waiting time of users in the process of graphic code verification, at present, offline graphic codes that can be generated offline by graphic code display devices and verified offline by scanning code devices have also begun to be widely used in various fields. application. For example, consumption scenarios such as scanning codes in and out of subway stations, campus cafeterias, convenience stores, and bathrooms. [0003] However, the code value of the offline graphi...
