Biometrics, as used in the security industry, is defined as methods for uniquely recognizing humans based upon physical traits. The person is authenticated by utilizing some unique feature about themselves. Examples of a biometric measurement would include, fingerprints, retina characteristics, voice recognition or signature dynamics.
Smart cards utilize a physical trait combined with the smart card data to authenticate a card holder and authorize entrance into a controlled environment. The smart card holds embedded information in the internal chip that identifies the intended card holder. When access is desired the card is held up for a reader to extract the embedded information. The biometric scanner reads the physical trait of the person “requesting” access. This could be a capture of a person’s fingerprint, eye scan or other configuration. If the information from the card and the capture of the person’s characteristic match, the computer software is able to proceed to the next step. That step determines whether or not the person is authorized to access the area at that point in time. If so, the access is granted.
This form of authentication is fast, accurate and much more secure than most programs currently in place.
