Abstract

A mobile information terminal that can authenticate an authorized user by using behavioral features acquired when the user makes small movements in a limited movable range is provided. The mobile information terminal includes a gripping feature sensor that acquires gripping features; a behavioral feature sample acquisition section that acquires time-series data of gripping features in a fiddling session as samples of behavioral features; a switch that puts the mobile information terminal into either a learning mode or an authentication mode; a template learning section that learns an authentication template by using the samples of behavioral features when the mobile information terminal is in the learning mode; an authentication section that authenticates the user by comparing the samples of behavioral features with the learned authentication template when the mobile information terminal is in the authentication mode; and an unlock section that unlocks all or some of the functions of the mobile information terminal when the authentication succeeds.

Description

technical field [0001] The present invention relates to a mobile information terminal, a method for learning behavioral characteristics, and a method for authenticating behavioral characteristics by acquiring behavioral characteristic samples during manipulative movements for personal authentication. Background technique [0002] In recent years, various money-related services, such as electronic money, have become popular with the improvement of mobile information terminals. In addition, with the high functionality of mobile information terminals, many information related to personal privacy, such as address books, emails, photos, and website browsing history, are recorded on mobile information terminals. Conventionally, when using a mobile information terminal, the security of information handled by the mobile information terminal has been ensured through personal authentication at the start of use. In recent years, biometrics authentication using biological information h...
