Embodiment Construction

[0070] In order to solve the problem in the prior art that verification code verification fails when the cache server is down or the network is abnormal, the present invention proposes a verification code verification method and device.

[0071] The implementation principle of the verification code verification method provided by the embodiment of the present invention is: in the verification code verification method provided by the embodiment of the present invention, the terminal initiates a verification request to the server, and after the verification server receives the verification request sent by the terminal, it assigning a verification code to the terminal, and sending the assigned verification code to the cache server for caching, and the verification server uses a private key to encrypt the assigned verification code and its validity period to generate an encrypted string, and then use Image steganography writes the generated encrypted string into the verification co...

Abstract

The invention discloses a verification code verification method and device, which are used to solve the problem in the prior art that the verification code verification fails when the cache server is down or the network is abnormal. The verification code verification method includes: a verification server receiving a verification request sent by a terminal; distributing a verification code for the terminal according to the verification request, and sending the distributed verification code to a cache server for caching; using a private key to verify the distribution of the verification code and Its validity period is encrypted to generate an encrypted string; use image steganography to write the encrypted string into the verification code picture carrying the assigned verification code, and return the verification code picture to the terminal; receive the verification code input by the user sent by the terminal, and obtain The verification code that is cached by the cache server for the terminal is verified, and the verification code is verified; when it is determined that the verification code cached by the cache server fails, the cache exception information is returned to the terminal, so that the terminal can match the verification code entered by the user with the verification code. The verification code image is used for local verification code verification.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a verification code verification method and device. Background technique [0002] The existing verification code verification method is based on cached data as the verification standard. The verification code generated by the verification server each time will be cached by the cache server in advance. After the user enters the verification code, the content of the verification code in the cache is obtained for verification. [0003] Such as figure 1 As shown, it is a schematic flow chart of an existing verification code verification method, including the following steps: [0004] Step S11, the terminal sends a verification request to the verification server. [0005] In this step, the user sends a verification request to the verification server through the terminal. [0006] Step S12, the verification server assigns a verification code. [0007] In this step, the...
