Abstract

The invention provides a man-machine verification method based on common knowledge, which improves the security of a verification code on the basis of ensuring user friendliness so as to effectively improve the accuracy of man-machine verification. The method comprises the following implementation steps: 1, constructing an image quantity list and a keyword list; 2, obtaining a verification code based on common knowledge; 3, generating a user verification interface of the man-machine verification system; 4, acquiring click behavior information of the user; 5, obtaining a man-machine verification result. According to the invention, the common knowledge is applied to the generation of the verification code by utilizing the difference of the understanding degrees of people and machines for thecommon knowledge, the difficulty of cracking the verification problem by an artificial intelligence algorithm is increased when the man-machine verification system performs man-machine verification on the user, and the security of the verification code is improved, so that the accuracy of the man-machine verification is effectively improved, and the risk that the Internet is maliciously attackedbased on an artificial intelligence algorithm in network scenes of login, registration and the like is reduced.

Description

technical field [0001] The invention belongs to the technical field of safety protection and relates to a man-machine verification method, in particular to a common sense-based man-machine verification method, which can be used for man-machine verification of users in network scenarios such as login and registration. Background technique [0002] Human-machine verification is a Turing test that distinguishes between computers and humans fully automatically. Its design and implementation mainly includes verification codes, user verification interfaces, and human-machine judgment systems. The difficulty of man-machine verification is to ensure the accuracy of man-machine verification results. The higher the accuracy of man-machine verification results, the lower the risk of the Internet being maliciously attacked based on artificial intelligence algorithms in network scenarios such as login and registration. An important indicator of machine verification accuracy is the securi...
