Sign-in verification method and system based on reverse byref

Abstract

The embodiment of the invention discloses a sign-in verification method and system based on reverse byref. The method comprises the steps that a mobile terminal generates verification information according to target site location information and a target identity and uploads the verification information to a server for storage; the mobile terminal sends a verification request to the server, thereby obtaining a verification result; if the verification result comprises the fact that the mobile terminal is equipped with a positioning function and the positioning function is started, the mobile terminal receives scan operation of a user for the target identity, thereby obtaining analysis information, and obtains target identity scan time information and current location information of the mobile terminal; the mobile terminal generates sign-in information according to the analysis information, the time information and the current location information and uploads the sign-in information to the server; and the server carries out sign-in verification on the sign-in information according to the verification information. Through application of the embodiment of the invention, allograph is effectively prevented, and an onsite sign-in rate is ensured.

Description

technical field [0001] The invention relates to the technical field of sign-in, in particular to a sign-in verification method and system based on reverse address transfer. Background technique [0002] Two-dimensional code is to record data symbol information with a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules; ", "1" The concept of bit stream uses several geometric shapes corresponding to binary to represent text and numerical information, and automatically reads through image input equipment or photoelectric scanning equipment to realize automatic processing of information: it has some advantages of barcode technology Commonality: Each code system has its specific character set; each character occupies a certain width; it has a certain verification function, etc. At the same time, it also has the function of automatic identification of information in different rows, and the processing of graphic rotation and chan...
