In earlier days, password system invented first for security. As time progress, hackers found the methods to destroy the password security systems. Afterward accessformula. Still, in some companies this system is working. It really is good and fast and possesses another advantages at the same time. However, the issue arrives at more confidential places or resources continue to have some doubt in your mind. Is it enough for security? I do believe, no certainly not. We require a more secure system which concerns some other factors. Biometric access control systems are definitely the answer.
These are related to form of the body. Let’s take some example. Fingerprint, it ought to be unique for those people. Palm print can be another trait. Face recognition is an additional one. In face recognition, the factors include distance between two eyes, distance between nose and ear, measurements of the nose, any blot, blemish etc. Most advanced technology contains eye retina scan. Overall, each of the factors which uniquely identify a person.
These are based on behavior of the individual. For example, typing rhythm. System requires typing some words and identifying the person in line with the rhythm. Other trait is gait; a slight difference must be there from the gait of each and every people. Another factor is voice. There are plenty of systems already in the market 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 individual who wishes to access secure resource. Then match that data using the captured biometric data saved in database. On that basis, system verifies the one who he promises to be. If system founds that person as an authorized person then allows him/her to access the secure biomtrics or resources. Another usage of biometric system is to determine a particular person from the bulk of people. System works same manner as in the last case. It scans the folks individually and matches the criteria. When match happens system alerts the administrator.
In the end, little discussion on performance versus the investment. It is actually just once cost system. It requires almost nil maintenance. It will require update of the database. You have to enter the data of authorized persons first, against that 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 hard, in-fact extremely hard. Therefore, without doubt at heart in regards to the security that Biometric Security Access Control Systems provides.
