With increasing security threats faced by many firms from both internal and external sources, face recognizing technologies are being adopted as the measure to protect the firms are round the globe. Just like other biometric systems such as the finger print technology and iris identification technology, this technology too depends on the unique features that are unique to an individual. This is what has been exploited by facial recognition security companies to reap huge benefits.

The principle behind the facial recognition technology is the use of computers to capture facial images, compare them with the ones in the database and provide a feedback. The digital images are used to automatically verify a person and allow or deny access to a specific system, rooms or even work stations.

The these security firms have gone to the next step of using three dimensional face recognition systems, an improvement on the earlier systems with even better results. These are known to capture specific features in the face and use them for the recognition purpose. Unique facial characteristics such as eye socket contours, the nose alignment or even the mouth shape are some areas that will be relied on for this purpose.

With 3D facial recognition, there are even greater advantages such as ability to recognize the user from various angles and with diverse light sensitivity. This is something that was a challenge with the earlier systems. In addition to this, the system also processes data very fast and give feedback in a matter of seconds.

It is predicted that such authentication codes like passwords will soon be replaced by personal identification technologies, and indeed facial recognition companies are the ones leading in this aspect. They fall both in the categories of the users and the creators. The practicality of the system is as a result of efforts the manufacturers are putting to develop affordable yet highly effective hardware and software used for this purpose.

An example of how the system works can be seen where the computer automatically logs off when the use is away and logs on automatically again after recognizing the presence of the user. Such computers can be used by a number of users without jeopardizing the information in the system as each of users get access to their own accounts only. This is particularly very important in the areas dealing with sensitive information in open offices and shared machines such as security firms, financial sectors and hospitals among others.

Some other areas in which this technology is used include protection of sensitive areas such as storage of sensitive items, monitoring of the employee reporting and leaving times, and can also be used as a source of crucial evidence in case of a security breach.

If the improved performance and increased profitability is anything to go by, then it is easy to notice that facial recognition security companies are making a huge kill as a result of this technology. More and more companies are set to adopt the same system particularly if the developers are able to come up with even cheaper, effective and efficient solutions in this sector.
