A verification code verification method and device

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: the verification server receives the verification request sent by the terminal; distributes the verification code for the terminal according to the verification request, and sends the distributed verification code to the cache server for caching; utilizes the private key to verify the distribution of the verification code and its Encrypt the validity period to generate an encrypted string; use the preset audio steganography algorithm to write the encrypted string into the verification code audio for playing the assigned verification code, and return the verification code audio to the terminal; receive the verification code input by the user sent by the terminal, And obtain the verification code cached by the cache server for the terminal distribution, and verify the verification code; when it is determined that the verification code cached by the cache server fails, return the cache exception information to the terminal, so that the terminal will input the verification code according to the verification code entered by the user. Verification code audio 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 audio verification code uses the audio signal as the carrier to play the verification code in the form of voice. The existing audio verification code verification method is based on the cached data as the verification standard. The verification code generated by the verification server will pass the cache in advance The server caches, and 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 audio 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 verificatio...
