The invention provides an intelligent identity
authentication system. The intelligent identity
authentication system comprises an
authentication client SDK, an
authentication server SDK, an authentication service proxy device, an
authentication server, an authentication analysis engine and a cloud service platform, wherein the authentication
client SDK is used for acquiring
client information of authenticated users; the
authentication server SDK is used for checking service strategies, and executing and forwarding information of an authentication client; the authentication service proxy device is used for providing a
server reverse proxy when the authentication
server SDK cannot implement an authentication function; the authentication
server is used for managing the service strategies, authentication
modes and cases, and displaying authentication analysis results; the authentication analysis engine is used for performing risk analysis based on a
risk control model, wherein the risk analysis includes the steps of performing
risk level scoring based on predefined rules and implementing
big data analysis in combination with a
big data analysis engine; and the cloud service platform dynamically adjusts identity authentication
modes and requirements according to risk analysis results of the authentication server and the authentication analysis engine, performs identity authentication for the users, and returns an authentication result to the authentication analysis engine. According to the intelligent identity
authentication system provided by the invention, an appropriate identity authentication mode can be selected for the users based on a risk
analysis method.
