INTRODUCTION
The term biometris derived from greek words
Bio means life and metric means to measure
introduction
It is associated with utilization of distinctive physiological characteristic for identifying individuals .
Though most important application related with biometrics is that of security,it is used as computer interface too.
A range of biometrics application are being used for authenticating person’s identity.
FINGERPRINTS
Fingerprint recognization is identify by using patterns of friction ridges and valleys on an individual fingertips which are unique to that individual
IRIS
Iris scanning seems futuristic but it uses simple DIGITAL CCD camera.
It uses both visible and near infrared light to take a clear,high contrast picture of iris.
In the scanner,camera focuses to make sure that the position is correct and eye is kept 3 to 10 inches from camera.
When the camera takes a picture the computer locates.
CONCLUSION
Successful applications
Decreasing cost and increasing convenience
Increasing both privacy and identity security
The field of biometrics is evolving
Benefit from technology
