Hand Geometry in Biometric Security


Hand geometry in biometric security is an approach to security that involves the geometric shapes and structure of the hand tissues of user authentication. People have unique hand features that can be used as biometric identifiers hence the essay is aimed at using hand geometry in enhancing biometric security.

Hand geometry

The common security measure that is used by many organizations is fingerprints. However, through fingerprints, it would not be easy to identify the owner of the fingers prints with the naked eyes (John Chirillo, 2003). This system is prone to errors hence high rate of inaccuracy. In spite of the failure to achieve the perceived  outcome on using finger prints, technological advancement enables the security systems to involve the biometric geometry in determining a secure measure through electronic systems, which are able to encode user data and store for future verification purposes (John Chirillo, 2003).

Inline authentication process that involves the use of fingerprints, the human hand is not unique either, verification would still be accomplished through the use of a hand thickness of a hand, curvature and the length among other features for identification (John Chirillo, 2003). However, when dealing with matters of security like immigrating departments and boarder control systems, it is adept to not to involve the invasive biometric since this would infringe of user privacy (John Chirillo, 2003).

Such a situation requires a sufficient biometric system that would be used for verification proposes (John Chirillo, 2003).  Geometry would be desirable since it is not distinctive and the process involved in collecting information and data on hand geometry is effortless to accomplish. The process of data collection would require a hand and fingerprint collection through the biometric imaging system integrated with a retina- recognition system (John Chirillo, 2003).

Through a special light from the biometric machine, the machine would encode the required unique security identifiers.  The fingerprints would be used in the biometric system for infrequent identification while the full hand would be used for frequent verification (John Chirillo, 2003).

In conclusion, hand geometry is a security measure that is capable of producing personal information on an individual’s identity as fed through a biometric system. Through the acquisition device that capture and stores user data, such information could be professed and be used anywhere within the global scope without fear or favor. Hence it is adept to reiterate that hand geometry can be used in biometric security.
