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

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
