3. What Is Biometric? Biometric is a combination of two Greek words Bio(Life) and Metric(To Measure). It actually measures and analyzes the biological traits of a human being. Biometric is the automated process of identifying or verifying an individual based upon his or her behavioral or physical characteristics.

4. History Of Biometric System Security The first known example of Biometrics in practice was a form of finger printing being used in China in the 14 th century, as reported by explore Joao de Barros. He wrote that the Chinese merchants were stamping children’s palm print and footprints on paper with ink to distinguish the young children from another.

5. Biometric Devices & Its Work Area Types of Biometric According to it’s working principle Biometric device are mainly two types- 1.Behavioral -Voice -Signature -DNA 2.Physical -Fingerprint - Palmprint -Face -Hand geometry -Iris

6. Biometric Devices & Its Work Area In generally these devices are used any where, required core security. Such as- The Banking sector Company employee attendance Store data Send data/wealth Now a day for attendance in school these device are used. ATMs

7. Why Biometric Required? Identity theft is not possible Password remembrance problem does not exist Cannot be predicted or hacked Cannot be shared Perceived as more secure

8. Working Of Biometrics System These devices are work through some steps- Capturing Pre-processing Feature extension Template matching Matcher/Comparison Application device

9. Working Process Of Biometrics System In the first step the device receive data through sensor then convert it some feature extraction and make some template to store database. In feature this device compare these template to the user/client.

10. Working Process Of Biometrics System For storing data in computational memory devices are first scan the finger/input device then make equivalent graphical view for converting it memory matching view. Devices are convert finger/input device its equivalent binary value and store, in future compare any finger/input device with the storing data.

11. Comparison with any Other Devices Electronic/other Devices May be theft Break the password Forgotten password Biometric Devices Not possible to Theft. Impossible to break the Password No chance it is machine dependent

12. Limitation Of Biometric System Presence of noise in the sensed data Variations in the enrolled data Non-universality It is an expensive security solution

13. Disadvantage Of Biometric Costly Facial imagine can also hinder Accurate identification The scanning of eye is fearful Missing body part is problem False acceptance and rejection

14. Conclusion Biometrics-based authentication has many usability advantage over traditional system such as password. The greatest strength of biometric, the fact that the biometrics does not change over time, is at the same time its greatest libility . Once a set of biometric data has compromised, it is compromised forever.
