In earlier days, password system invented first for security. As time progress, hackers found the methods to interrupt the password home security systems. After that accessformula. Still, in many companies this technique is working. It is good and fast and it has some other advantages also. However, the issue arrives at more confidential places or resources still have some doubt under consideration. Will it be enough for security? I feel, no certainly not. We must have a much more secure system which concerns various other factors. Biometric access control systems will be the answer.
These are related to model of our system. Let’s try taking some example. Fingerprint, it ought to be unique for all people. Palm print is another trait. Face recognition is an additional one. In face recognition, the factors 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, all of the factors which uniquely identify somebody.
These are based on behavior of the person. For example, typing rhythm. System requires typing some words and identifying the person in accordance with the rhythm. Other trait is gait; a slight difference has to be there inside the gait of every people. Another factor is voice. There are plenty of systems already in the market which works on voice recognition. Countless other aspects are in this category.
How Biometrics access controls works? The system functions on verification. One particular system can consider multiple trait, which can be discussed earlier. Means system verify all criteria. System scans the individual that would like to access secure resource. Then match that data with all the captured biometric data kept in database. On that basis, system verifies the person who he states be. If system founds that person as being an authorized person then allows him/her to access the secure biomtrics or resources. Another use of biometric product is to determine a specific person from the bulk of people. System works same manner as in the earlier case. It scans the folks one at a time and matches the criteria. When match happens system alerts the administrator.
By the end, tiny bit discussion on performance up against the investment. It is actually 1 time cost system. It will take almost nil maintenance. It will require update in the database. You must enter in 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 difficult. Therefore, without doubt at heart concerning the security that Biometric Security Access Control Systems provides.
