In earlier days, password system invented first for security. As time progress, hackers found the ways to interrupt the password security systems. After that accessformula. Still, in a few companies this method is working. It is good and fast and has various other advantages also. However, the problem arrives at more confidential places or resources still need some doubt under consideration. Would it be enough for security? I think, no not at all. We must have a more secure system which concerns various other factors. Biometric access control systems are definitely the answer.
These are related to model of our system. Let’s try taking a little example. Fingerprint, it must be unique for all people. Palm print is another trait. Face recognition is another one. In face recognition, the standards include distance between two eyes, distance between nose and ear, size of the nose, any blot, blemish etc. Most advanced technology contains eye retina scan. Over all, each of the factors which uniquely identify somebody.
These are related to behavior of the person. For instance, typing rhythm. System requires typing some words and identifying the individual in accordance with the rhythm. Other trait is gait; a little difference needs to be there from the gait for each people. Another factor is voice. There are numerous systems already in the marketplace which works on voice recognition. So many other aspects happen to be in this category.
How Access Control works? It functions on verification. Just one system can consider more than one trait, which is discussed earlier. Means system verify all criteria. System scans the one who wishes to access secure resource. Then match that data with the captured biometric data stored in database. On that basis, system verifies the person who he claims to be. If system founds that person as an authorized person then allows him/her gain access to the secure biomtrics or resources. Another usage of biometric technique is to identify a particular person from the majority of people. System works same way as in the previous case. It scans the people one after the other and matches the criteria. When match happens system alerts the administrator.
By the end, little bit discussion on performance up against the investment. It can be just once cost system. It takes almost nil maintenance. It needs update of the database. You must go into the data of authorized persons first, against that the system does verification. Security level of biometric access control systems is quite high then a older systems based on password or identity cards. These systems require creating duplicate biometric traits to hack, which happens to be quite difficult, in-fact nearly impossible. Therefore, certainly in mind concerning the security that Biometric Security Access Control Systems provides.
