Abstract: An information verification method based on a cloud security technology is provided. Before transmitting to-be-verified information including user information, a terminal device performs encryption processing on the to-be-verified information by using random numbers and a public key issued by a verification server, to obtain to-be-verified ciphertext information, which is to be used throughout transmission for logging into a server of a third-party application. The server of the third-party application cannot decrypt the to-be-verified information and the to-be-verified information may be obtained only by the verification server. The verification server transmits an application login success message to the terminal device based on decryption processing on the to-be-verified ciphertext information. In this way, the server of the third-party application may be logged in to without exposing privacy information of a user to the third-party application, thereby improving the security of identity verification.
