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 video for playing the distributed verification code by using a preset video steganography algorithm, and returning the verification code video to the terminal; receiving a verification code input by a user and sent by a terminal, obtaining the verification code cached by the cache serverand allocated to the termi
