Biometric Systems is automated systems of recognizing or verifying an individual’s identity based on some specific physical characteristics, such as a fingerprint or hand print, or any combinations of physical characteristics, such as voice or hand movement. biometric system use sophisticated software to collect, record, and compare biological information of individuals. These systems provide the best possible results when it comes to matching individuals with their own unique biometric traits and qualities. This is the reason why today there are more businesses and organizations opting for biometric authentication systems over more traditional methods such as verifying an individual’s identity by means of his or her credit card or other financial documents.
However, despite the availability of such sophisticated tools, human accuracy is still considered to be better than machine accuracy in determining the presence of individuals. There are various biometric verification systems in the market. Some of these systems use thumb printing or finger prints, while others use hand prints or other types of physical characteristics that are difficult to fake or copy. The most commonly used biometric systems collect, record, and verify biometric information of individuals through various physical means, such as fingerprints or hand prints. However, modern biometric verification devices can also employ digital biometric data such as facial recognition, iris recognition, fingerprint scanning, retinal scans, hand print scanning, or facial recognition. As soon as the biometric data of individuals are accurately processed and deciphered by the device, the stored information is then matched with the biometric data of the individual.
In spite of the effectiveness and reliability of biometric systems, there are still some major setbacks and limitations of this system. First, fingerprints and hand prints are often too generic in nature to match well with specific individuals. Second, in case of very old or recently lost keys or documents that contain pertinent, biometric information, it becomes almost impossible to retrieve these records and information from elsewhere as well.
