Emerging Technology Meaning


Biometric technology uses intrinsic human features such as fingerprints, handprints, facial characteristics, irises or retinas in voice, the eyes, and several other things for identification purposes. Biometrics security systems are growing rapidly because they're considered more secure than conventional security systems. After all it is much more difficult to steal or duplicated a fingerprint than it is to do likewise with a key or a word.

Yes, it is possible but not likely to fool biometric systems and if the system is fooled it will happen only once. In addition to recognizing fingerprints, biometric systems are sophisticated enough to recognize body temperature and blood flow to make sure the finger presented comes from a live human being and not merely a molded replica. Secondly, fingerprints are never exactly the same twice due to human factors. The fingerprints will be similar enough to identify individuals when scanned but if an exact replication of a previously scanned fingerprint is scanned again, the biometric system will know it and deny access.

I wonder if this has been considered?

The speed at which fingerprints are identified is dependent on two factors. The first factor is the speed or processing power of the system. The second factor represents the number of fingerprint templates in the database. Obviously more templates means increased processing time. In any event, identification speed ranges from one to two seconds so either way it is very quick.

Generally no but if the finger scanned is too dry, the quality of the images may not be enough to create a suitable template. This is rare but the outcome will be a 'false reject' which means the system falsely rejects you. All you will need to do is breathe on your finger or rub your fingers together to provide moisture and try again.

So you can see biometric technology is quite advanced. The systems are already quite accurate and difficult to fool. And as with most emerging technologies, biometric systems are advancing at a rapid rate so get used to them. It may not be long until you get a biometric security system installed in your home.
