INTRODUCTION
Biometrics is a rapidly evolving technology
Facilitates the automatic identification based on physical or behavioral characteristics
Eliminates the need to memorize a password or carry some form of token
WHAT IS A BIOMETRIC ?
Science and technology of measuring and statistically analyzing biological data that is represented in human by patterns unique to
every individual
TYPES OF BIOMETRIC SYSTEM
Fingerprint Verification
Hand Geometry
Retinal Scanning
Iris Scanning
Facial Recognition
Signature Verification
Voice Verification
DETAIL ANALYSIS OF IRIS SCANNING
Iris scan takes about 30sec & 2sec for verification
A camera located at about 3 feet focuses on & scans iris from one side
This scan is converted into a template
Only phase information is used for recognizing iris as amplitude information is depends on extraneous factors
