In earlier days, password system invented first for security. As time progress, hackers found the ways to destroy the password security systems. Afterward accessformula. Still, in a few companies this system is working. It really is good and fast and possesses another advantages too. However, the problem arrives at more confidential places or resources continue to have some doubt in your mind. Would it be enough for security? I think, no not at all. We must have a far more secure system which concerns various other factors. Biometric access control systems would be the answer.

These are related to model of our body. Let’s try taking a little example. Fingerprint, it must be unique for all people. Palm print is yet another trait. Face recognition is another one. In face recognition, the factors include distance between two eyes, distance between nose and ear, scale of the nose, any blot, blemish etc. Latest technology contains eye retina scan. Overall, all of the factors which uniquely identify an individual.

These are based on behavior of the person. As an example, typing rhythm. System requires typing some words and identifying the person in line with the rhythm. Other trait is gait; a slight difference has to be there in the gait of each people. Another factor is voice. There are so many systems already in the market which works on voice recognition. Countless other aspects have been in this category.

How Access Control works? The system functions on verification. A single system can consider a couple of trait, which is discussed earlier. Means system verify all criteria. System scans the person who wishes to access secure resource. Then match that data using the captured biometric data held in database. On that basis, system verifies the individual that he states to be. If system founds that person for an authorized person then allows him/her gain access to the secure biomtrics or resources. Another consumption of biometric technique is to distinguish a particular person from the bulk of people. System works same way as in the previous case. It scans individuals one after the other and matches the criteria. When match happens system alerts the administrator.

At the end, little bit discussion on performance against the investment. It is just once cost system. It takes almost nil maintenance. It takes update in the database. You must enter the data of authorized persons first, against in which the system does verification. Security amount of biometric access control systems is extremely high then a older systems according to password or identity cards. These systems require creating duplicate biometric traits to hack, which can be quite difficult, in-fact nearly impossible. Therefore, no doubt at heart about the security that Access Control System Buying Process provides.
