Problems solved by technology
[0002] At present, verification codes are usually set up for user registration, login or other channels for verification. The verification codes set are all displayed as a dot matrix verification code for users to input or click content for verification, and there is no brute force cracking of the program. In order to prevent brute-force cracking, some verification codes keep shrinking the characters and overlapping each other, so that the naked eyes can’t tell them apart

Embodiment Construction
[0057] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0058] see figure 1 , is a verification code security defense method of the present invention, comprising the steps of:
[0059] S100: The server generates first verification code information; and then transmits the generated first verification code information to the client. The generation may also be that the client retrieves some data from a previously received verification code database as the first verification code. Wherein, the verification code information may be implemented in the form of pictures, animated gifs, texts, letters, and the like.
[0060] The client proceeds to step S102: generating second verification code information based on the first verification code information, the second verification code information is...

The present invention provides a verification code security defensing method, system and apparatus. The method comprises the following steps of: generating first verification code information; based on the first verification code information, generating second verification code information, wherein the amount of the second verification code information is less than that of the first verification code information; displaying the second verification code information in a client; receiving to-be-verified data in the client; determining whether the to-be-verified data and the second verification code information are the same; and when it is determined that the to-be-verified data and the second verification code information are the same, displaying verification success information in the client. The method, the system and the apparatus provided by the present invention effectively improve the security of using verification codes.
Description
technical field [0001] The invention relates to the application field of verification codes, and in particular relates to a method for security defense of verification codes. Background technique [0002] At present, verification codes are usually set up for user registration, login or other channels for verification. The verification codes set are all displayed as a dot matrix verification code for users to input or click content for verification, and there is no brute force cracking of the program. In order to prevent brute-force cracking, some verification codes keep shrinking the characters and overlapping each other, so that the naked eyes can't tell them apart. Contents of the invention [0003] Therefore, it is necessary to provide a verification code security defense method to improve the security of the verification code. [0004] In order to achieve the above purpose, the inventor provides a verification code security defense method, including the following step...
