The phrase biometics is generally used to describe a kind of household device which turns back into energy when switched off. If you hear it described as a biosafe then this is most likely because these are also called biometics. What are biometics? These are devices that protect individuals from becoming a victim of crime or illness by performing specific tasks when they turn off. They have become very important in recent years, and many of the public transport companies offer them for security reasons. These can be used on trains, buses and anywhere else a vehicle might turn off and on.
Why do we need biometics? These very small devices or biometics as they are sometimes referred to are very important in identifying a person. This is usually done using fingerprints or facial recognition technology. For example, if you were to rob a bank and made your getaway with an armed robber, this thief would not have a set of fingerprints so you could rule out the possibility that he was not wearing a biometric system that identified him. Instead, you could simply use the system at the bank to identify the thief.
This works well in theory. You take a photo of the face and scan it into a biometric scanner, which will tell you if that particular fingerprint belongs to the person in question. In practice however, the results from such a scanner are often conflicting. Because the way in which facial recognition technology works means that we are processing too many data for it to reliably identify a real person. As a result, we often make mistakes in our identification of people.
How can biometics help? These systems rely on several factors including hand geometry, facial recognition, skin texture, hair color, and similar characteristics. A biometric system that identifies one person but matches an incorrectly matched fingerprint to that person can be an invitation to false arrests and false convictions. If a biometric system cannot reliably match a fingerprint, then it is not serving its purpose. If a hand geometry is mismatched, for instance, a robbery suspect who is thought to be a professional thief may be a drug user with a habit of taking cash from wallets.
However, there are ways that biometics can be used to reduce mistakes in biometics identification. For instance, if you go to a security camera and see an unknown face, rather than typing that person’s name into the system to match their eye color, you can take the picture yourself and run it through the program to check for matching characteristics. This also applies to iris patterns. The iris pattern of a face is unique to each individual, and so if you take a picture of someone and then run that picture through a biometric scanner, it should match the specific iris pattern of that person. This way, biometics is useful as a way of verifying the identity of individuals as they walk past security cameras.
Biometics which work with iris recognition processes use image recognition for processing fingerprints or iris recognition fingerprints. This is because fingerprints and iris patterns are unique to each individual. An image recognition system, however, needs a good camera for identifying a face. Iris recognition systems are commonly used when the criminal needs to identify an individual after a theft or burglary. With a good iris recognition process, the police will have a high chance of identifying a particular individual with a high level of accuracy.
Some biometics use facial recognition technology. Facial recognition technology is very accurate, as it usually works by checking the physical features of a face (eye, nose, hair, and skin color). However, the iris of each person is different and therefore cannot be recognized by facial recognition technology. In this case, biometics which utilize iris recognition technology can be used instead.
There are also biometics which have been designed specifically to work with iris patterns. These biometics use iris recognition fingerprints to read the information on the retina. These biometics provide a higher level of security than traditional biometics, as they offer a high degree of accuracy. However, iris biometics is not able to be used with iris biometric data, and must rely on the signature provided by the fingerprint reader.
