Two of the most popular biometric security systems work on the model of either fingerprint recognition or palm vein technology. The first type of biometric security device uses the fingerprint recognition technique where a highly sensitive camera captures the thumb prints of the individuals. The person has to place his thumb over the scanner, which then captures the fingerprint and matches it with existing records. The biometric device is mostly used for fingerprint recognition, fingerprint verification, fingerprint authentication, fingerprint scanning and fingerprint matching applications. The device is so designed that it is able to capture dry, wet and blurred images as well. The other kind of biometric security device with palm vein technology uses an infrared sensor that identifies an individual's vein pattern. This method works on a very sensitive model of authentication technique. This type of biometric security system does not require being touched; the user has to place the hand over a few inches on the scanner. Palm veins are unique to every individual and with the help of infrared sensor; the scanner captures this never-changing pattern. The biometric device is also an option because of its hygiene mode. In traditional biometric security systems, the device was required to be touched, making way for sanitary issues that are now dealt with, Both these fingerprint access control devices incorporate those features of the humans that do not change or are not prone to any manipulation. Factors like age, wounds, cuts, change in skin colour do not make up for any difference unlike the earlier counterparts of these biometric devices. This paper discusses general biometric security systems. This paper reviews different biometric security systems.
