Question

Biometrics uses biological information to verify identify. The basic idea behind biometrics is that our bodies contain unique properties that can be use to distinguish each of us from all other human beings.discuss the latest technology in identification techniques. how are some related to historical bases?

Answer 1

1. Wanted posters with drawing or pictures of the accused.
2. Fingerprints
3. DNA database
4. Rental Images.

All these are ancestors to the original biometric database or forms of early biometrics. The idea that a picture of someone is good way to distinguish them is as old drawing and probably pre-dates writing by many years. Before that it was personal descriptions and that 'technology' is as old as the spoken word, maybe even older.

Throughout history we have been trying to identify ourselves to keep track of each other to separate ourselves from others and to find or track others.

When it came to criminals the idea was to limit their operation and freedom and to eventually capture them. DNA databases are just the most modern evolution of what started with verbal descriptions and that is older than history.

Fingerprinting was the first reliable biometric because the print is unique to the individual and that is not subject to interpretation. Computerization was the next big advance. Until the computerized database you had to have a suspect to use fingerprints, now day’s fingerprints allow you to find a subject, just as DNA does. It also allows you to separate innocents.

Biometrics came into its own when we started to use them to control access. The CBS TV show NCIS illustrates this when they use an optical scanner to gain entrance to the complex.

We have had fingerprint scanners for computers for years; the idea of a DNA scanner is an old one. At first people thought a blood sample would be needed, but now days we can find a suitable sample with just some spit. In the future only someone's breath will be needed an the skin cells from the lung will be enough to get a DNA match.

The next generation of biometrics will use a living finger, checking not only the print, but the pattern of the blood vessels behind it. This will be used to access our debit and credit accounts from remote terminals and has already been started in some pilot programs.
