In earlier days, password system invented first for security. As time progress, hackers found the ways to break the password security systems. After that identity cards invented. Still, in some companies this system is working. It is good and fast and has some other advantages as well. However, the issue arrives at more confidential places or resources still have some doubt in mind. Is it enough for security? I think, no not at all. We need more secure system which concerns some other factors. Biometric access control systems are the answer.

As I have stated earlier, it is based on several physical and behavioral aspects.

Physical Traits

These are related to shape of our body. Let’s take some example. Fingerprint, it must be unique for all people. Palm print is 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. Latest technology contains eye retina scan. Over all, all the factors which uniquely identify a person.

Behavioral Traits

These are related to behavior ...
... of the person. For example, typing rhythm. System requires typing some words and identifying the person based on the rhythm. Other trait is gait; a slight difference must be there in the gait of every people. Another factor is voice. There are so many systems already in the market which works on voice recognition. So many other aspects are in this category.

How biometric access control system works? It works on verification. A single system can consider more than one trait, which is discussed earlier. Means system verify all criteria. System scans the person who wants to access secure resource. Then match that data with the captured biometric data stored in database. On that basis, system verifies the person who he claims to be. If system founds that person as an authorized person then allows him/her to access the secure premises or resources. Another use of biometric system is to identify a particular person from the bulk of people. System works same way as in the previous case. It scans the people one by one and matches the criteria. When match happens system alerts the administrator.

At the end, little bit discussion on performance against the investment. It is one time cost system. It takes almost nil maintenance. It requires update of the database. You need to enter the data of authorized persons first, against which the system does verification. Security level of biometric access control systems is very high then the older systems based on password or identity cards. These systems require creating duplicate biometric traits to hack, which is very hard, in-fact nearly impossible. Therefore, no doubt in mind about the security that biometric access control system provides.

Today, biometric access control systems are worldwide popular systems. Even biometric passports are in the trend. Most of the countries have adopted biometric passports. Looking at the threat of terror attack and other threats biometric passport is the best option. Biometric access control systems are very fast. The premises, where thousands of people pass every day, these systems are very useful. At last, “prevention is always better then cures”. So takes some security steps to prevent the attacks and make your life secure.
