In today’s world, due to various amounts of advancements happening and the sensitive data being generated, security has become a primary concern. To address this biometrics came into the scene, and now we see them being used on a personal level such as laptops, cell phones etc to major industries for authenticating employees, restricting access of data except for a select few etc.
The term “biometrics” is derived from the Greek words “bio” (life) and “metrics” (to measure). Many biometric systems have been developed for this purpose of which the palm vein technology is the latest in the field. Automated biometric systems have only become available over the last few decades, due to significant advances in the field of computer processing. Many of these new automated techniques however are based on ideas that were originally conceived hundreds, even thousands of years ago.
One of the oldest and most basic examples of characteristics that are used for recognition by humans is the face. Since the beginning of civilization, humans have used faces to identify known (familiar) and unknown (unfamiliar) individuals. The simple task became increasingly more challenge as populations increased and as more convenient methods of travel introduced many new individuals into once small communities. The concept of human- to- human recognition is also seen in behavioral- predominant biometrics such as speaker and gait recognition. Individuals use characteristics, somewhat unconsciously, to recognize known individuals on the day-to-day basis.
