Intelligent mobile phone user identity certification method based on writing behavior biological feature

Abstract

The present invention relates to an intelligent mobile phone user identity certification method based on a writing behavior biological feature, belonging to the field of information safety technology. The method comprises two parts which are training and certification. In a training period, firstly a user selects or customizes a stamp and writes, then the touch information in a writing process and mobile phone sensor information are collected, the writing behavior biological feature is extracted, and finally the writing behavior biological feature is stored for certification. In a certification period, firstly, the user copies a stamp prompt stored in the training period, then the touch information in a writing process and mobile phone sensor information are collected, a writing behavior biological feature is extracted, and the similarity between writing behavior biological feature and the writing behavior biological feature stored in the training period is calculated, whether the similarity is larger than a threshold value or not is calculated, the certification is approved if so, and the certification is failed if not. Compared with a traditional certification method, the certification method of the invention has the advantages of convenient certification process, large improvement of safety, convenient use of the user, and no need of remembering complex passwords.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to a smart phone user identity authentication method, in particular to a smart phone user identity authentication method based on biological characteristics of writing behavior. Background technique [0002] With the rapid development of the mobile Internet and the widespread use of smart phones, smart phones have become an important carrier of personal privacy information and online payment. The rapid development of social software, game accounts, online shopping payment, e-commerce and mobile banking on mobile phones makes identity authentication on mobile phones increasingly important. The task of identity authentication is to verify the legitimacy, authenticity and uniqueness of the identity of the user who accesses the system, and then decide whether to allow the user to access the specified system, resource or service and other functions. [0003] Among the identit...
