Research direction for masters


Owner authentication using face recognition
in camera phone (or PDA)


Copyright protection for digital music


Biometric watermarking using IrisCode

Owner authentication in
mobile devices


Smartphone and PDA are getting more
powerful and popular, thus owner
authentication becomes an important issue


PDA + mobile phone + camera


Using
Biometric feature

for owner authen.


Fingerprinting


Face recognition


IRIS recognition

Example devices using
biometric authentication


HP iPAQ 5550






指紋辨識隨身碟

指紋辨識器







Sony MS
指紋辨識卡

Motivation: camera phone and
PDA


More mobile phones and PDA will have
build

in camera for
biometric recognition


IRIS recognition?


無法近拍


Face recognition


Challenge:


Face recognition is an old topic, and recognition rate is
low


Limited memory and CPU power in mobile devices


Port program to different OS

Copyright protection for digital
music


Piracy behavior in the


Approach


Watermarking + Encryption


Difficulty


Study the MP3 format

Biometric watermarking using
IrisCode


Current scheme to generate watermark


Random bitstream


Hash function


=> Meaningless watermarks


Using IrisCode as the unique watermark


Difficulty


Implement Daugman
