A test was recently carried out by the International Biometric Group on a variety of security systems for 25 sponsors. The results showed that consumers prefer fingerprint scans to voice, facial or signature scans, with the least favourite methods being keystroke scans and traditional passwords.
Fingerprint scans were the most popular because they were fast and easy to use. Results showed that the biometrics methods were more popular with consumers, but they were also less accurate than other methods in some cases. Behavioral biometrics have improved in accuracy, but it should be noted that fingerprint systems must be designed to accommodate the effects of weather and changes in skin surface. Biometric systems were more accurate in this test than in a similar 1998 test – they improved in three categories: verifying authorized users, rejecting unauthorized users, and ensuring that nearly everyone can use them. The price of biometric hardware devices has fallen since 1998, and sales during 2000 almost doubled from the previous year.
