Biometric systems

What is biometric ?

• Biometrics is the technology, which uses various individualistic attributes of a person to verify his or her identity. Various attributes include fingerprints, geometrical shapes of hands, retina, and iris in the eyes and so on. Biometric test offers a full-proof and highly secure method of verification to avoid security breech and unauthorized access to critical data and places.

Various Characteristics Involved

The characteristics used by biometrics technology are divided into two groups - physiological and behavioural.• Physiological characteristics involve face recognition, handprints and

fingerprints, veins in hands, capillary vessels in eyes and so on.• Behavioural characteristics involve voice modulations, handwriting and

signature style, and keystroke dynamics.

Biometric system

• Biometric system is advanced methods to induce systematization and security at various places like business organizations, building demanding sophisticated protection and even the residential areas. Utilizing specific attributes, these systems can help maintain the much-deserving security level. Corporate houses are facilitated by these biometric systems to assess performance of employees and increase their calibre.

Face Recognition Biometric System

• Faces differ on the basis of individuals belonging to different cultures, races, genders and geographical locations. Biometric techniques make use of distinctive face nodal points and use them for authentication process. Face images are captured, even without informing the person and stored in database for future identification. Banking, law enforcement and custom department are few fields utilizing these systems.

Fingerprint Analysis Biometric System

• Against the ordinary belief, fingerprints-based biometric analysis store only specific features, like ridge endings and bifurcations, of fingers in digital form, instead of capturing exact finger image. Electronic commerce, law enforcement, computer and laptop access are few fields, where these biometrics systems are finding applications. Also, biometric clocks in offices are based on fingerprint analysis to keep an eye on employee presence.

Voice Recognition Biometric System

• On the basis of throat and mouth shapes and sizes, voice recognition biometric techniques are becoming popular with business and other organizations for carrying our biometric analysis. The voiceprints act as passwords for individuals to authenticate their entry to various places. Special care is taken to handle the modifications in voice textures and interference of other voices from surroundings.

Signature Verification Biometric System

Styles of signing the names differ from an individual to another. Formation of words, angles of signing and speed and pressure employed are few factors, which can form the basis of admirable biometric tools. Banks, e-commerce and other fields requiring signature verifications use these systems.

Other Biometric Systems in the Market

• Hand geometry recognition based biometric tools make use of dimensions, surface area and shape of hands and are used for residential as well as commercial purposes.

• Algorithms and 2D and 3D imaging facilitate iris recognition systems to use the structure and patterns of eye vessels as identification tools.

• Vein structures at the back of hand also form the basis for biometric systems.

• Keystroke dynamics, involving speed of typing and pressing various keys, are among other useful biometric techniques.
