Intelligent terminal identity authentication method based on similarity

Abstract

The invention provides an intelligent terminal identity authentication method based on similarity. The method comprises a training period and an authentication period, used for solving the technical problem that in an existing implicit authentication method, authentication accuracy is relatively low. The method comprises implementation steps of acquiring a training data set, pre-processing a training vector set, computing similarity between behavior feature distribution probability vectors in the training vector set based on information entropy to train a user behavior feature model, and presetting an identity authentication threshold; and if an authentication password is completely matched, preprocessing a current behavior feature sequence to acquire the current behavior feature distribution probability vector, acquiring a current average similarity, judging whether a difference percentage of the current average similarity to the user behavior feature model is within a preset identity authentication threshold range, and acquiring an authentication result. The method provided by the invention is high in security and good in user experience, and can be applied to user identity authentication of smart phones and tablet computers.

Description

Technical field [0001] The invention belongs to the technical field of identity authentication, and relates to a smart terminal identity authentication method, in particular to a similarity-based smart terminal identity authentication method, which can be used for user identity authentication such as smart phones and tablets. Background technique [0002] Identity authentication is the process by which the system confirms the identity of the visitor when a computer system user enters the system or accesses system resources with different protection levels. The main idea of ​​identity authentication is: if the identity authentication information provided by the visitor of the current computer system matches the identity authentication information of the existing legitimate user, the current visitor is considered to be legitimate and the access operation is allowed, otherwise the access is denied operating. The purpose of identity authentication is to control the system's authoriz...
