What is biometric ?How biometric works ?Operating modesTypes of biometricsApplications of biometricsAdvantages & Disadvantagesconclusion
Biometrics refers to the automatic identification of a person based on his or her physiological or behavioral characteristics .
DEFINITION OF BIOMETRICS
Types of Biometrics Physiological
Face Fingerprint Retina Iris recognition
Behavioral Signature Voice
Facial Recognition
1. Capture image
2. Find face in image
3. Extract features (store template)
4. Compare templates
5. Declare matches
Finger print recognitionA fingerprint scanner
has two basic jobs.It needs to get an image
of your finger.
It needs to determine whether the pattern of ridges and valleys in this image matches pattern of ridges and valleys in pre-scanned images.
Signature Verification An automated method of measuring an individual’s signature.
This technology examines speed, direction, and pressure of writing; the time that the stylus is in and out of contact with the “paper’’.
Speaker / Voice Recognition
Voice or speaker recognition uses vocal characteristics to identify individuals using a pass-phrase.
A telephone or microphone can serve as a sensor.
Application
Criminal identificationPrison securityATM and other Financial TransactionsPC/LAN LoginAttendanceBorder crossing controls
Advantages of Biometrics
Biometrics are generally used for authentication. It provides higher security .e.g. Iris recognition .Voice Recognition works well over the telephoneUser friendly
e.g. Hand geometry recognization,
finger print recognition.
Disadvantages of Biometrics
Retina recognization requires close physical contact of the scanning device, may not be generally accepted by public
CostlyVoice recognization requires large amount of computer
storage, people's voices can change, background noises can interfere.
Biometrics features may change over time.Signature recognization has poor long-term reliability,
accuracy difficult to ensure.
Conclusion
Technology is growing rapidly, but at the same time security breaches and transactions frauds are also in the increase world over.
All agencies including libraries who are in need of security and safety have to adopt biometrics
Let us hope for safe and secure future.
