In earlier days, password system invented first for security. As time progress, hackers found the ways to break the password security systems. Next accessformula. Still, in many companies this system is working. It can be good and fast and contains some other advantages too. However, the situation arrives at more confidential places or resources have some doubt in mind. Could it be enough for security? I feel, no certainly not. We must have an even more secure system which concerns another factors. Biometric access control systems will be the answer.
These are related to form of the body. Let’s try taking a little example. Fingerprint, it should be unique for those 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, size of the nose, any blot, blemish etc. Most advanced technology contains eye retina scan. Over-all, all of the factors which uniquely identify a person.
These are related to behavior of the person. For example, typing rhythm. System requires typing some words and identifying a person based on the rhythm. Other trait is gait; a small difference should be there from the gait of every people. Another factor is voice. There are numerous systems already in the market which works on voice recognition. So many other aspects have been in this category.
How Biometrics access controls works? The system functions on verification. An individual system can consider multiple trait, which happens to be discussed earlier. Means system verify all criteria. System scans the one who wants to access secure resource. Then match that data with the captured biometric data held in database. On that basis, system verifies the individual who he promises to be. If system founds that person as being an authorized person then allows him/her to access the secure biomtrics or resources. Another utilization of biometric method is to recognize a selected person from the bulk of people. System works same way as in the previous case. It scans the individuals one after the other and matches the criteria. When match happens system alerts the administrator.
At the conclusion, little bit discussion on performance versus the investment. It is once cost system. It requires almost nil maintenance. It takes update from the database. You must go into the data of authorized persons first, against which the system does verification. Security amount of biometric access control systems is extremely high then this older systems based upon password or identity cards. These systems require creating duplicate biometric traits to hack, which can be quite hard, in-fact nearly impossible. Therefore, undoubtedly at heart in regards to the security that Access Control System Buying Process provides.
