Biometrics is not a new term and was orginally derived from the Greek words “bio” (life) and “metrics” (to measure). However, automated biometric systems have only become available in the last couple of decades due to computer processing and advances in technology. Many of these techniques used today were based on concepts conceived hundreds or even thousands of years ago.
Since the beginning of civilisation the face was the most recognised and is the oldest form of biometrics. Humans have used faces to identify known and unknown individuals. As populations increased the simple task became more challenging.
Other characteristics have also been used throughout civilisation:
1. 31,000 year old walls which are believed to be adnorned with numerous handprints that are felt to act as an ”unforgettable signature.”
2. There is evidence that fingerprints were used as a person’s mark as early as 500 B.C and recorded in clay tablets.
