Power plant computer monitoring system identity authentication method and system

The invention discloses a power plant computer monitoring system identity authentication method and system. The method comprises the following steps: triggering fingerprint capture based on a received login request; acquiring fingerprint information based on fingerprint capture; preprocessing the fingerprint information to obtain first information; extracting a plurality of fingerprint features based on the first information; the fingerprint features are matched with a preset database, if the obtained matching degree is larger than a preset threshold value, user information corresponding to the fingerprint features is obtained, and password capture is triggered; then obtaining input information; and acquiring password information corresponding to the user information based on a preset database, and if the input information is consistent with the password information, determining that the identity authentication is successful. The method is high in safety, high in reliability and accurate and efficient in auth
