Abstract

The invention discloses a generation method, a verification method and a device for a universal verification code of a person and legal equipment, and the method comprises the steps: generating a first background picture of the verification code, and storing the corresponding generation time; encoding the generation time by adopting an encoding rule to obtain encoded data corresponding to the generation time; dividing the first background picture into a plurality of time region pictures, and preprocessing the time region pictures to obtain a second background picture; performing region division on the second background picture to obtain a verification code character region picture, randomly generating a verification code character in the verification code character region picture, randomly generating a verification code character in the verification code character region picture, and adding an interference rule to the verification code character to obtain a universal verification code for people and legal equipment. And universal verification of people and legal equipment is realized. According to the verification code generated by the method, the universality between a person and legal equipment can be realized, the identification speed of the equipment is higher, and the authentication efficiency is high.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a generation method, verification method and device for common verification codes for people and legal equipment. Background technique [0002] The verification code is to generate a picture with a string of randomly generated numbers or symbols, add some interference factors to the picture, let the user identify the character information with the naked eye, enter the form and submit it to the website for verification, and only after the verification is successful can a certain function be used. [0003] Recognition of verification code pictures: the verification code technology is designed to distinguish between humans and computers from the beginning, and to identify verification codes by using the insimulation of the human brain. It is difficult for computers to identify, but people can easily identify them. In order for the device to recognize the verification code ...
