Verification code based on image content

Abstract

The invention discloses a verification code based on image content. A verification code system comprises a verification code module, a service logic module, a database and the like. According to the verification code, images are selected through the system according to selection rules, verification questions based on image content semantics are selected from content based on image targets, the verification questions are displayed at a user access terminal, a user is required to answer the verification questions as the verification code, the user reads the images and the verification questions to fill in the verification code, the system compares verification answers filled in by the user with corresponding answers of the verification questions corresponding to the selected images, and if the verification answers filled in by the user are consistent to the corresponding answers, the verification code of the user is correct. By means of the verification questions generated on the basis of the image semantics and the corresponding verification code serving as the answers, safety of the verification system is improved, and automatic identification of a machine program is effectively prevented.

Description

technical field [0001] The invention relates to system software and the technical field of the Internet, in particular to a verification code based on image content. Background technique [0002] With the development of Internet technology, especially software technology, it is feasible to provide a verification code based on image content. [0003] At present, in the system login interface, in order to prevent the automatic login of automatic machine programs, the system provides a verification code system on the login interface for defense. The traditional verification code method is a scrambled text image method. With the development of image recognition technology, pure Text and picture verification codes can already be read and cracked by machines, and the security needs to be improved. However, complex scrambled verification code images make it difficult for users to read and often require multiple attempts to enter the verification code correctly, resulting in poor us...

[0003] At present, in the system login interface, in order to prevent the automatic login of automatic machine programs, the system provides a verification code system on the login interface for defense. The traditional verification code method is a scrambled text image method. With the development of image recognition technology, pure Text and picture verification codes can already be read and cracked by machines, and the security needs to be improved. However, complex scrambled verification code images make it difficult for users to read and often require multiple attempts to enter the verification code correctly, which leads to poor user experience.
