Biometric Locks: The Future of Entry Security, Today

What are Biometric Locks?

It has been a really long day at the office. You lock up and drive home. At the door, you reach in your pocket just to discover that you have forgotten your key . . . again. You whip out your cell phone and dial your spouse, cringing as the phone rings. You are in for a world of hurt, buddy. The truth is that keys are an outdated technology. The key was first invented in Egypt about four thousand years ago, and it really hasn't changed a whole lot since. Almost everyone has lost their keys or had them stolen at some point. The security risk posed by a key may actually outweigh the benefit of using one. In the current era, with crime escalating to new heights, concerned citizens need a new solution for entry security in both homes and businesses. It seems like in this age of lightning fast communication and dizzying electronic capabilities, we could find a security solution that shields the occupants of a home from burglary and break-ins while also allowing a convenient and secure entry method. After much research into the viability of different options for entry security, a clear winner has emerged. The science of biometrics, the process of identifying a person based on physical or behavioral traits, has now created affordable biometric locks. Biometric locks use examination and identification of a trait to allow access into a home or business. This technology can be invaluable in protecting a home.

Who Can Benefit from A Biometric Lock?

Home owners are one of the top groups who can benefit from the installation of a biometric lock. The locks, which allow for a greater amount of security, are becoming more and more popular among people who are concerned about the safety of their home. Because the traits examined by a biometric system are very difficult to replicate, a biometric lock poses very little risk of intrusion. The convenience of a biometric lock dwarfs that of a traditional lock and key. Because biometric locks assess qualities which are intrinsically located on your body at all times, it is highly improbable that you will suddenly be without a hand or an eye.

Businesses also appreciate the convenience and security of biometric locks. Using biometric locks can reduce the threat of break ins and allow for the introduction of restricted areas. Authorizing only certain employees for entrance into a room can be a great way to protect sensitive files within a business.

What Types of Biometric Locks are Available?

There are several types of biometric locks available for purchase, each with features unique to models and brands. The most popular type of biometric lock is the fingerprint scanner. This type of lock examines the geometry of a fingerprint to make positive identifications. After a positive match is found in the system, the door unlocks. There are a number of biometric fingerprint-driven locks with a cornucopia of characteristics. The basic fingerprint scanning biometric lock has a few key components:

  • An Optical Sensor
  • A digital sensor is used to read the fingerprints.

  • Software
  • Software is integrated into the hardware and is used to analyze fingerprints in comparison with those in the database.

  • Door Hardware
  • This includes the door handle, lock, and in some cases, touch pads, traditional keys, and remotes as backup methods of entry.

    Extra options for biometric fingerprint locks include keypads, emergency keys, and web based servers. The locks can accommodate up to 20,000 users, depending on the model. Different settings can be used for different users of the lock. The variability among models requires furious scrutiny of the type of biometric fingerprint lock available. Finding the options just right to suit your needs without becoming excessive calls for a balanced approach.

    A second type of biometric lock is the iris scan lock. Iris scanners analyze points of reference in people's eyes. This solution is more ideal for a business situation in which higher amounts of security are required to restrict access. Eye scanners have the same types of extras as fingerprint scanners, and can be surprisingly affordable. These eye scanners are becoming more popular as a form of entry security.

    A third type of biometric lock is the vein scanner. Vein scanners use infrared light to examine the nearly impossible to replicate vein geometries in the hand or arm. Vein scanners are a newer technology and a little more difficult to find. However, if you need top notch security, there is no substitute for a good vein scanner.

    How Do Biometric Locks Work?

    The concept behind biometric locks comprises a few central steps. The first is enrollment, in which the person's fingerprint, iris, or vein pattern is initially recorded. The next step is storage, where the biometric trait is translated into a graph or code. At this point, the different access settings for the biometric traits of different individuals. This includes time sensitive entry and event logs for certain users. After the storage of a biometric trait comes identification, in which a trait of a person is compared to the matching trait in the database. If an identification is correct, the lock will open. If a person is unauthorized by the system, the door will remain locked. With such an easy concept, and such a secure method of entry protection, biometric locks are a very nice choice for convenient protection of a home or business.
