Abstract: One embodiment of the present invention provides a system that facilitates identity verification based on various features of a card. During operation, a server receives a request for identity verification, where the request corresponds to an account and includes an image of a verifiable card. The server extracts a card feature from the verifiable card image for use as a verifiable card feature. In response to determining that the verifiable card feature matches a corresponding card feature of a registered card of the account, the server determines successful identity verification.

Abstract: A human biological characteristic file corresponding to a particular identity is received and used as a base file. A characteristic code to be authenticated is obtained according to a human biological characteristic of a person who requests identity authentication when an identity authentication request corresponding to the particular identity is received. A base characteristic code is collected from a base file. A collecting algorithm applied for collecting the base characteristic code is the same as or matches an algorithm applied for obtaining the characteristic code. The present techniques determine whether the base characteristic code and the characteristic code correspond to a same human biological characteristic. If a result is positive, the identity authentication request is verified.
