Authentication method and system based on third-party certification authority

An embodiment of the invention discloses an authentication method and system based on a third-party certification authority. The method includes: when the third-party certification authority authenticates an authentication object user, the third-party certification authority stores authentication information and allocates at least one authentication service code to the authentication object user; the third-party certification authority receives an authentication result query request, and analyzes the query request to obtain the authentication service code; and the third-party certification authority feeds back the corresponding authentication information to a result query user whose initiates the query request according to the authentication service code. The authentication method based on the third-party certification authority solves the problem that authentication results of an existing authentication method cannot be mutually accepted or used. The third-party authentication certification authority performs authentication for one time, and various scenes can use the authentication information, thereby achieving an effect that authentication results can be mutually accepted and used, and the method is convenient and rapid.
