Jacob Delgado CSYS 3350 ?BIOMETRICS? Delgado 1 Recent technological advances in the computer industry are opening up a brave new world of convenience and security. Once regarded to realms of fantasy, such as the late 60?s show Star Trek, where the ship?s computer would easily respond to Captain James T. Kirk?s voice commands, this technology will soon be viable and affordable. Biometrics is the measurement of living traits, whether physical or behavioral. Biometrics, by definition, is not a new technology. However, the computer industry has advanced it severely. Some of the traits that biometrics can measure with today?s technological advances are Hand, Retina, Iris, Facial, Voice, and Finger scan. This paper will allow you to learn what each biometric device is used for and it?s current implication amongst financial institutions, the business community, chemical industries, automobile manufacturers, government agencies, internet access, and allows you to see some of the current problems associated with biometrics.The following are brief information and description on what each biometric device measures: ? Hand Scan uses hand geometry, which is not distinct enough to identify random people. There have been six different hand-scanning products developed over the span of two decades, including the most commercially successful biometric to date, the ID-3D Handkey from Recognition Systems. The Handkey, of which nearly 4,000 were sold in 1995, looks at both the top and side views of the hand using a built-in video camera and compression algorithms. The reference template is less than 10 bytes, the smallest in the industry. Dirt and cuts do not detract from Delgado 2 performance, and the hand can be guided easily into the correct position for scanning.? The Retina Scan is accurate, but invasive. The retina scan involves a beam of light that allows the computer scanner to access the blood vessel pattern on the back of the eye, which provides a unique base for identification. It requires the user to stand at a designated point and stare at a designated target and ideal conditions.? The Iris Scan is also extremely accurate. The technique's major advantage over retina scanning is that it does not require the user to focus on a target, because the iris pattern is on the eye's surface. In fact, the video image of an eye can, theoretically, be taken from several feet away, and the user does not have to interact actively with the device. The iris pattern is reflected back to a camera, which captures the unique pattern and represents it using less than 35 bytes of information. The toughest hurdle for these technologies continues to be user acceptance.? Facial Scans can scan and identify people in a crowd without their cooperation or knowledge. The allure of facial recognition is obvious. It is the method, which most resembles the human trait of the memory used to recognize the identity of people. Facial image can be captured from several meters away using...
