Conventional user authentication methods for smartphones using PINs, passwords, pattern locks, etc. have a problem in that user authentication is not performed continuously after the first authentication success; therefore, there is a risk that an authenticated smartphone might be used improperly by unauthorized individuals. We propose a novel continuous authentication method for smartphones that uses face images and touch-screen operation and evaluated its effectiveness.
