Verification interactive method, associated device and communication system

Abstract

The embodiment of the invention discloses a verification interactive method, an associated device and a communication system. The method comprises a receiving a verification request message from a client, a step of sending a first verification interactive message comprising N1 sub images to the client, wherein the N1 sub images comprise a bottom image and N1-1 option images, the bottom image comprises N1-1 deletion areas, the length of an external rectangle of a deletion area j is smaller than that of an option image i, and / or the width of the external rectangle of the deletion area j is smaller than that of the option image i, and a step of determining a verification result based on a connected image and a verification image if a second verification interactive message comprising the connected image obtained by connecting the N1 sub images from the client is received. According to the embodiment of the invention, the improvement of the ability of preventing malicious client brute force in the verification process is facilitated.

Description

technical field [0001] The invention relates to the technical field of Internet security, in particular to a verification interaction method, a related device and a communication system. Background technique [0002] Verification codes are commonly used in Internet business, and are used as an additional verification method against batches of malicious clients. Verification codes are mainly used in scenarios such as account registration, account login, forum posting, and Weibo speeches. [0003] The jigsaw verification code is a new type of verification code. The server cuts a verification picture into multiple sub-pictures and sends the multiple sub-pictures to the client. After the client splices multiple sub-pictures to obtain a spliced ​​picture, the spliced ​​picture is sent to the server, and the server determines whether the verification is successful according to the comparison result of the spliced ​​picture and the original verification picture.

Problems solved by technology

[0005] The inventors of the present invention have found in the course of research and practice that there are at least the following technical problems in the prior art: since current malicious clients mainly stitch sub-pictures based on the similarity of sub-picture edges, this makes existing Technology becomes more difficult to prevent malicious clients from brute-forcing during the verification process
