Problems solved by technology

[0004] However, since both the Jiugongge and the display area are Chinese characters, although the shapes, fonts or colors of the Chinese characters in the two areas are different, or there are occlusion interferences, as long as they are the same Chinese character, they can be found by calculating the similarity of the pictures. Therefore, the existing Jiugongge verification code has a high probability of being cracked, and the security of input verification is low

Abstract

The embodiment of the invention provides an input validation method. The input validation method comprises the following steps: sending a first picture corresponding to a first semantic meaning and a second picture corresponding to a second semantic meaning to a client, wherein the first semantic meaning is associated with the second semantic meaning; receiving operation information sent by the client, wherein the operation information is information obtained by operating the second picture through the client according to an operation instruction, and the operation instruction is triggered by a user according to the first semantic meaning and the second semantic meaning; validating the operation information according to validation information corresponding to the first picture. The embodiment of the invention also provides an input validation device. According to the technical scheme provided by the embodiment of the invention, the safety of input validation is improved.

Description

【Technical field】 [0001] The invention relates to Internet application technology, in particular to an input verification method and device. 【Background technique】 [0002] With the increasing emphasis on network information security, more and more verification methods have emerged. Among them, input verification is a way to distinguish users from computers and people. , forum flooding, malicious login attempts, etc. [0003] Verification codes are usually verified through character information, by showing users deformed or disturbed character images, such as figure 1 As shown in the Jiugongge verification code, the Jiugongge verification code includes the Jiugongge and the display area. The Jiugongge includes nine Chinese characters, and each Chinese character can be clicked. The display area includes four Chinese characters; in the Jiugongge, click the four displayed in the display area. Chinese characters, if all are selected correctly, the input verification is success...
