Biometric verification is not the same as biometric identification, and it is important to understand what the difference is between verifying someone and ascertaining their identity.
There is only a small difference between the two in actual function, but the cost of a biometric verification system is much lower than the cost of a biometrics identification system.
If you are considering getting either one of these biometrics identity verification systems, it is important to know what the differences are going to be between the two because the biometrics technologies are for both are advancing everyday.
Bio verification is basically verifying that you are who you say you are. If you press your fingerprint on the scanner of verification devices, the device has to access the database of the fingerprints and determine that your biometrics pattern is actually authorized to open whatever it is that you are trying to access.
For example, if you are the owner of a biometrics safe, you will scan your fingerprint on the access scanner. The biometric sensor will look into its database of fingerprints that are authorized to open the device, and it will verify if you are one of the people that are authorized to open it.
It is basically looking through a limited number of access codes to see if you are getting the right one. You have to input a certain code or information, and your fingerprint is scanned to be certain that you are who you say you are. Fingerprint verification and even signature verification is basically the final test to be certain that you are the person who your information says you are.
Ascertaining your identity via bio identification is a bit more complex, as the identification process requires a much more complete system. With iris identification, you are basically identifying yourself only from your pupil pattern, and nothing else.
Rather than inputting a code or special information that will grant you access to the device you are trying to open, only your fingerprint or palm pattern will allow you to open it.
Take a fingerprint scanner at a large company or corporation. Anyone that wants to gain access to the building will have to place their fingerprint on the scanning device, which will then sift through the entire database of fingerprints to find the one that matches.
Seeing as the fingerprint is the only identifying mark that will set you apart from the average Joe trying to access the building, the biometrics identification device will have to be very thorough and check your fingerprints to be sure that they are allowed access to the building. The scanner then brings up your identity as being one of the ones permitted entrance, and the doors slide open.
To sum it up, biometric verification is the final test to determine that you are who you say you are, using your fingerprints to back up the information that you input into the system. Biometrics identification is basically identifying you from all the rest of the people allowed access to a certain location, and is a much more complex process that requires more sophisticated devices.
If you can afford the extra expense, the finger print input devices are well worth the cost, as they are much more advanced and will provide you with a simpler access control system that guarantees even more protection and control than any other kind of system.
Biometrics is basically the recognition of human characteristics that are unique, which can include facial recognition, retina scans, palm prints, fingerprints, voice recognition, and more.
