User Authorization Method based on Face Recognition for Auto Network Access in Home Network System

Abstract

Security is very important under home network environment that provides trustworthy services after
personal information authentication. Especially, reliable user authentication technology is needed to
provide various tailored smart services for individual users at a home network system. This paper
suggests a user authentication technique using long-distance face recognition to provide a safe home
network service. For the long distance face recognition test, face images by actual distance from 1m-
5m away were obtained directly. Both actual and virtual face images taken by distance were applied
to resolve the issue rising from distance change while histogram equalization and MCT were used as
a preprocessing to address the illumination change. The test result showed that an LDA-based face
recognition algorithm that used histogram equalization as a preprocessing and face images by actual
distance for training was found to show the best performance, so it is expected to be applicable for
user authorization of home network system.
