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 afterpersonal information authentication. Especially, reliable user authentication technology is needed toprovide various tailored smart services for individual users at a home network system. This papersuggests a user authentication technique using long-distance face recognition to provide a safe homenetwork 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 appliedto resolve the issue rising from distance change while histogram equalization and MCT were used asa preprocessing to address the illumination change. The test result showed that an LDA-based facerecognition algorithm that used histogram equalization as a preprocessing and face images by actualdistance for training was found to show the best performance, so it is expected to be applicable foruser authorization of home network system.
