Retina - Biometric Computer Security Systems
The next security technology that explained in this report is retina security technology which is very famous in a lot of spy movie. Although retina is an outstanding and perfect security device, it can not be popularized in human’s daily life. Firstly, retina contains a large amount of vessels which absorbs more light than the surrounding area. The retina scanner device can recognize retina by casting a ray of low energy light into human’s retina when they see through the device. However, according to Biometric Scanner (2009), the person who wants to be recognized should concentrate his eyes on the scanner device for more than 10 seconds. The description stated above is the principle of operating retina scanning device.
According to the principle of retina scanner, it is actually a dependable security system. However, a lot of scientists continually study for the ray from the device because users still doubt whether the ray is harmful for human’s eyesight or not (Biometric Scanner 2009). Furthermore, using this security system is not only time consuming, but also making user uncomfortable due to the 10 seconds concentration. With this drawbacks and the expense, retina can not be commonly used at present society.
