Abstract

The invention provides an identity authentication method and system. The method comprises the steps of collecting voice signals, fingerprint image data and face image data of a user; extracting spectrum features of the voice signals to obtain voiceprint feature information; converting the voiceprint feature information, the fingerprint image data and the face image data into a voiceprint matrix, afingerprint image matrix and a face image matrix of preset dimensions; splicing the three matrixes to obtain identity matrix data; inputting the identity matrix data into a preset neural network model to obtain first biological feature data of the user; calculating the similarity between the first biological feature data and second biological feature data of pre-registered users; determining a target user corresponding to the highest similarity; returning a verification result showing that the target user passes the identity authentication if the highest similarity is greater than a preset similarity threshold; and returning the verification result showing that the target user does not pass the identity authentication if the highest similarity is smaller than or equal to the preset similarity threshold.

Description

technical field [0001] The invention relates to the technical field of computer security information, in particular to an identity authentication method and an identity authentication system. Background technique [0002] At present, smart terminals such as computers and smart phones have become important assistants in people's work and life. Shopping, financial management, filing, data storage, etc. through the user's device provide users with very convenient services, but it is followed by security issues such as user data and user property. Therefore, the user device side needs to solve the user's identity authentication problem. [0003] Traditional static passwords have great security risks. Although dynamic passwords can further protect user information security, they cannot solve the situation that user devices are hacked or lost. With the development of various human biometric identification technologies, people use voiceprint, fingerprints, face and other biologic...
