Problems solved by technology

[0004] However, with the rapid development of image recognition technology, the jigsaw verification code in the above-mentioned prior art is relatively easy to be cracked
Moreover, once the recognition difficulty of the jigsaw verification code is increased, the recognition rate of normal users will drop significantly, which will bring greater interference to users, reduce the data processing speed in the process of human-computer interaction, and also bring relatively large transformation costs.

Abstract

Provided is a safety verification method. The method comprises that a request for drawing a CAPTCHA is received, an original picture is obtained, the original picture is processed into a preset color to generate a first picture, and multiple second pictures are cut from the original picture; the jigsaw CAPTCHA is generated according to the first and second pictures; the CAPTCHA is returned to a sender of the request; a jigsaw picture, which is completed by a user and sent by the sender, is received, and the degree that the jigsaw picture conforms to the original picture is determined; and whether the user passes safety verification is further determined. The invention also provides a safety verification device. The safety verification method and device can greatly reduce the declassification rate of an automatic machine under the condition that the difficulty in identifying CAPTCHA is not increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a safety verification method and device. Background technique [0002] Captcha (CAPTCHA) is the abbreviation of "Completely Automated Public Turing test to tell Computers and Humans Apart" (Turing Test to Tell Computers and Humans Fully Automatically), and is a public fully automatic program to distinguish whether the user is a computer or a human. It can prevent malicious cracking of passwords, and effectively prevent hackers from continuously attempting to log in to a specific registered user with a specific program brute force cracking method. [0003] In the prior art, character verification codes as traditional verification codes have existed for a long time. In addition, the technology against bad guys is relatively mature, and the automatic machine cracking rate is getting higher and higher, and non-character verification codes are gradually being used. The...
