All That You Needed To Know About Biometric SecurityBiometrics refers to the study of methods of uniquely recognizing human beings on the basis of certain traits that are peculiar to one. Of late biometrics has ventured into the field of security big time and hence the term, "biometric security". The word biometric derives its roots from the Greek word bios that means life and metron, which means measure. For those of you who are wondering what biometric security is all about, it is nothing but the application of simple biometrics in various security devices. These security devices recognize a human being on the basis of certain intrinsic traits. These traits could be anything from a fingerprint to the facial expressions of a person. Biometric devices can even read the hand measurements, irises, and facial patterns too. A biometric lock, for instance, would require the fingerprint of the authorized person to open instead of a key. Thus while the keys, PIN numbers, and passwords of other locks and security devices can be transferred from one person to another access to these biometric devices cannot be transferred. It is only people who are authorized access to these security devices that will be able to get through it. Considering the basic principle on which security devices that use biometric application function, the security offered by them seems to be quite high. This is because stealing your keys, passwords or even PIN number is not that difficult a job. But on other hand it is rather quite hard to steal some one's fingerprints. Though that is not impossible but it is extremely complex and expensive to be done by any tom, dick and Harry. Owing to the high level of security offered by biometric devices, they are being used almost everywhere. These security devices are finding application both in the residential and commercial arena. There are several devices that function on biometrics. Some of them are fingerprint wall safe, fingerprint door lock, fingerprint password manager and many more. Adjust these devices with your laptop or affix tem to the door of your house and you can be rest assured. In the initial stage biometric security was only used for wall safes or door locks. But today it is even being used for data security. There are security applications that function on biometrics, which are designed to protect data in your computer system. Some devices even help you ensure the protection of your passwords. And needles to say, they turn out to be quite proficient in the job. With all this it goes without saying that biometric security is the future. The day is not far when biometrics would be used for almost everything from a single purchase to withdrawal. |
