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 for solving the problem of verification code verification failure when a cache server crashes or a network isabnormal in the prior art. The verification code verification method comprises: enabling a verification server to receive a verification request sent by a terminal; allocating a verification code tothe terminal according to the verification request, and sending the allocated verification code to a cache server for caching; encrypting the allocated verification code and the validity period thereof by using a private key to generate an encrypted string; writing the encrypted string into a verification code picture carrying the allocated verification code by using picture steganography, and returning the verification code picture to the terminal; receiving a verification code input by a user and sent by a terminal, obtaining the verification code cached by the cache server and allocated tothe terminal, and performing verification code verification; and when it is determined that acquisition of the verification code cached by the cache server fails, returning cache exception informationto the terminal, so as to enable the terminal to perform local verification code verification according to the verification code input by the user and the verification code picture.

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...
