Fingerprint identification. A ___________ looks at the patterns found on a fingertip. There are a variety of approaches to fingerprint ___________, such as traditional police method, using pattern-matching devices. It is a very good choice for in-house systems. Hand geometry. This involves analyzing and measuring the ___________ of the hand. It might be suitable where there are more users or where user accesses the system ___________. Accuracy can be very high if desired. Retina scan. A retina-based biometric involves analyzing the layer of ___________ vessels situated at the back of the eye. This ___________ involves using a low ___________ light source through an optical coupler to scan the ___________ patterns. Iris scan. An iris-based ___________ involves analyzing features found in the colored ring of tissue that surrounds the pupil. This uses a fairly ___________ camera element and ___________ no close contact between the user and the reader. Face recognition. Face recognition analyses facial ___________. It requires a digital camera to ___________ a facial image of the user for ___________. Because facial scanning needs extra peripheral things that are not included in basic PCs, it is more of a niche market for ___________ authentication. Signature. Signature verification analyses the way user signs his name. Signing features such as speed, ___________, and pressure are as important as the finished signature's static shape. People are used to signatures as a means of ___________-related identity verification. Voice analysis. Voice authentication is based on voice-to-print authentication, where ___________ technology transforms voice into ___________. Voice biometrics requires a ___________, which is available with PCs nowadays. DNA. DNA Biometrics could be the most ___________ form of identifying any given individual. The main problems surrounding DNA biometrics is that it is not a quick process to ___________ someone by their DNA. |
