There is currently no complete system for identifying people in areas where high security control is required. Current card or key systems identify authorization but not the person. Some biometric systems used to identify the person (for example, those who know the person’s voice) may be the “pirate” (for example, the recorded voice). Fingerprints are difficult to decipher if there are wounds or are stained. The eye recognition system also has barriers to starting it.

To this irreparable problem at a glance, has given solution the house “Art Techniques”, a system to know with biometrics the ear of the person. Each person has ears of size, relief and special shapes. In addition, over time they do not change due to their cartilage structure. In this retouching procedure, the ear is played with a piece similar to that of the phone. Take the image of the ear with an interior lighting system and a camera and compare it with the one you reference. Depending on the result of the comparison, open (or not) the door.

This new system, called “Optophone”, has many applications. Identify at bank ATMs who brings the credit card. Immediately neutralizes any lost or stolen card, as it has the owner's signature on chip. It can also be used as a security system in data banks. The numerical phone network allows sending the user's physical signature in 4 seconds. Therefore, in the central data bank one user cannot be replaced by another.

To prevent access to hazardous rooms or places, most systems so far are known as a containment stone or code. This system called “optophone” physically recognizes people and allows them (when necessary) automatic access, without any obstacles. Just use the “phone”.
