In earlier days, password system invented first for security. As time progress, hackers found the ways to break the password home security systems. After that accessformula. Still, in a few companies this method is working. It is good and fast and possesses another advantages at the same time. However, the situation arrives at more confidential places or resources continue to have some doubt under consideration. Is it enough for security? I think, no certainly not. We need an even more secure system which concerns another factors. Biometric access control systems are definitely the answer.
These are related to shape of the body. Let’s take some example. Fingerprint, it needs to be unique for all those people. Palm print can be another trait. Face recognition is yet 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 the factors which uniquely identify someone.
These are related to behavior of the individual. For example, typing rhythm. System requires typing some words and identifying the individual in accordance with the rhythm. Other trait is gait; a little difference must be there within the gait of each and every people. Another factor is voice. There are numerous systems already available in the market which works on voice recognition. A lot of other aspects will be in this category.
How Access Control works? The system functions on verification. Just one system can consider several trait, which can be discussed earlier. Means system verify all criteria. System scans the individual who would like to access secure resource. Then match that data together with the captured biometric data held in database. On that basis, system verifies the one who he promises to be. If system founds that individual for an authorized person then allows him/her gain access to the secure biomtrics or resources. Another consumption of biometric method is to identify a particular person from the bulk of people. System works same way as in the last case. It scans the people one at a time and matches the criteria. When match happens system alerts the administrator.
In the end, little bit discussion on performance versus the investment. It is once cost system. It requires almost nil maintenance. It will require update of the database. You should go into the data of authorized persons first, against in which the system does verification. Security level of biometric access control systems is incredibly high then the older systems according to password or identity cards. These systems require creating duplicate biometric traits to hack, which happens to be very hard, in-fact extremely difficult. Therefore, without doubt at heart regarding the security that Access Control System Buying Process provides.
