In earlier days, password system invented first for security. As time progress, hackers found the ways to get rid of the password home security systems. Afterward accessformula. Still, in many companies this method is working. It really is good and fast and it has a few other advantages too. However, the situation arrives at more confidential places or resources have some doubt at heart. Would it be enough for security? I feel, no not at all. We require an even more secure system which concerns another factors. Biometric access control systems will be the answer.
These are based on model of the body. Let’s try taking some example. Fingerprint, it needs to be unique for all those people. Palm print is another trait. Face recognition can be another one. In face recognition, the standards 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, every one of the factors which uniquely identify a person.
These are based on behavior of the individual. By way of example, typing rhythm. System requires typing some words and identifying the person in line with the rhythm. Other trait is gait; a small difference should be there inside the gait of every people. Another factor is voice. There are plenty of systems already available in the market which works on voice recognition. So many other aspects have been in this category.
How Access Control works? It really works on verification. A single system can consider multiple trait, which is discussed earlier. Means system verify all criteria. System scans the individual that wants to access secure resource. Then match that data using the captured biometric data stored in database. On that basis, system verifies the person who he states to be. If system founds that person as an authorized person then allows him/her gain access to the secure biomtrics or resources. Another use of biometric method is to distinguish a selected person from the majority of people. System works same way as in the earlier case. It scans the folks one after the other and matches the criteria. When match happens system alerts the administrator.
At the conclusion, bit discussion on performance versus the investment. It is one time cost system. It takes almost nil maintenance. It needs update of the database. You must enter the data of authorized persons first, against that the system does verification. Security degree of biometric access control systems is extremely high then the older systems based upon password or identity cards. These systems require creating duplicate biometric traits to hack, which happens to be quite hard, in-fact extremely hard. Therefore, no doubt at heart in regards to the security that Access Control System Buying Process provides.
