Biometrics technology is a security technology that uses the body as identity
. The medical world says that there are few parts of your body are very unique. It means that they are not owned by more than one individual. For example is fingerprint or retina.
Although the eye shape or eye color can be similar, the retina cannot be necessarily same. It also happens to the voice and facial structure. The unique parts are then developed as a security attribute. As parts of the security technology, biometrics has two functions that can be run separately or simultaneously. The first is as an ID recorder or as a means of verification (password).
Biometrics technologies can be applied virtually anywhere. This technology can be used to protect a particular item from unwanted access, such as computer. Also, it can be used to protect a crowded room from certain people. For example is to determine the existence of terrorists or other criminals at the airport.
This security technology works in the similar way with other security technologies that are dependent upon the sensor. Sensor that is used in biometrics technologies tends to be expensive. The more accurate the sharpness of sensor is, the more expensive it will be.
In addition to the sensor, the less important part of biometrics is the data. The way you store your data on a system is very crucial because biometrics is a technology that depends on data. When the data stored is unsafe or incomplete, the possibility of intruders to infiltrate into this system will be greater.
