Face Recognition Security Systems - Friend Or Foe?

Biometrics has changed our way of security these days, with technologies like fingerprint recognition commonly used to access high security areas such as those involved in the military high-level government security.

Although this is not the most popular biometric security today, the facial recognition security is becoming increasingly popular as facial recognition software and other technologies become more accessible and accurate.

How it works

Facial recognition security system works by storing individual facial features, and then comparing the structure, the distance from the eyes, mouth and nose, and the overall shape of the face based on the location and size of the cheekbones, nose and mouth, and eye sockets, and the outline of the jaw, all related to each other.

When the face to be used as part of a biometric security company, trades allow multiple images of himself to be taken, with different facial expressions and different angles. For verification standing questions on camera for a few seconds, and the resulting image is compared, using facial recognition software for images that have been previously recorded. For greater certainty, and that the masks can not be used to try to cheat the system, individuals will be asked to smile, wink or nod as they are verified and / or facial thermography can be used to measure the heat of the face.

What are the benefits of facial recognition security and disadvantages?

As you can imagine, there are advantages and disadvantages of this form of security.

Benefits:

Unnoticed, and can be used for monitoring, for example, when the government is preparing to criminals.

As technology improved, and cameras are included on most computer systems, facial recognition software can be a cost effective way to identify employees and others as needed.

And 'particularly effective when used in combination with other biometric methods (such as fingerprints) to facilitate the inspection and identification results for even more precise.

Disadvantages

· Can be inaccurate

In its current inca
ation, this warranty is still in its infancy. 2-D facial recognition software in particular can be affected by poor lighting or other environmental factors that may affect the accuracy. Although 3-D facial recognition software and technology does not exist, it is still quite expensive compared to older technologies.

· Require the frequent updating

Security facial recognition will also require frequent updates in order to remain accurate. Even if the fingerprint, for example, remain intact and unchanged throughout life, age influences the way they look, for this reason, such as age, the images should be updated on a regular basis to ensure data accurate is used. If they are not accurate, which were taken several years earlier, the system may erroneously exclude a person should or could ignore the individual who should not be given access.

· Allows a person can be identified without knowledge

The very thing that makes this security, so great is also a major drawback. Used positively, it allows an individual to be identified without their knowledge, when that person can be a danger to society and must be kept track of discretion.

However, that means it can also be used to track people without their knowledge, even if the situation warrants it. This raises questions about your right to privacy, requiring strict controls regarding the security and facial recognition can be used.
