Problems solved by technology

Even if the background verification code picture is added, if the background database is not large enough, it will still be cracked by the automatic machine
Therefore, the overall anti-cracking ability of the verification code picture is relatively poor, and the security is relatively low
[0005] In order to improve the anti-cracking ability of the verification code, the research and development personnel developed the click verification code. When the click verification code is used, it usually shows the user multiple pictures containing natural objects and prompt information related to the content of these pictures. Select these pictures according to the prompt information, and verify the user's identity according to the user's choice. Since the machine has great difficulties in understanding the prompt information and classifying objects, it can greatly increase the number of machine cracking. Captcha Difficulty
[0006] However, when the verification code is used, the image resource requirements are very high, and it needs to be manually screened and sorted into the warehouse, and the cost is high

Abstract

The invention provides an identity verification method and an identity verification device, which are low-cost, highly anti-cracking and highly safe. The method comprises the following steps that: a server receives a verification code pull request transmitted by a user terminal; the server randomly selects one verification code background picture according to the verification code pull request, and obtains a plurality of sub-pictures, a first splicing rule and a second splicing rule corresponding to the verification code background picture; according to a position and a rotation angle corresponding to each sub-picture in the first splicing rule, the server splices the plurality of sub-pictures in a plurality of vacant areas; the server issues the verification code background picture spliced with the plurality of sub-pictures to the user terminal to make the user terminal show the verification code background picture spliced with the plurality of sub-pictures to a user; and the server receives a splicing result of the verification code background picture and the plurality of sub-pictures, spliced again according to instructions of the user, from the user terminal, and performs verification according to the splicing result.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an identity verification method and device. Background technique [0002] With the increasing popularity of computers and computer networks, the Internet has penetrated into all areas of people's work, study and life. While the development of the network provides convenience for people, it also brings various challenges. Some people will use robot programs to improperly use network resources in large quantities, such as mass spam, etc., which will greatly reduce server performance. There are also people who use the program to continuously send out service request responses to carry out "saturation attacks" to achieve the purpose of paralyzing the server. Some people even try to maliciously crack passwords by means of profiteering cracking. In order to avoid the above-mentioned malicious behaviors, it is very important to design a set of tools that can allow the compu...
