Human Finger Knows It All

Unique conscience control device was invented in St.Petersburg

There have been several publications recently, saying that the unique device that was invented in St.Petersburg was awarded with a gold medal at the latest inventions show in Brussels. Mass media outlets called the device a lie detector. However, this is only one of a lot of possible variants to use the device.

Magnificent scientific developments could not be used anywhere in Russia after the collapse of the Soviet economy. Everyone was in need of a complete product. This eventually resulted in the birth of the enterprise Elsi. The company emerged at the end of the 1990s; it was established on the base of one of St.Petersburg research institutes. The goal of the new enterprise was to create complete products. The security issue was extremely actual back in those days. Control and access systems of that time were not able to meet modern requirements. As a result, there was a dactyloscopic chip invented in St.Petersburg – a small electronic thing with immense opportunities. Everyone probably remembers that a chip kicked off the story of the movie Terminator, starring Arnold Swarzenegger. As it turned out, the science fiction plot of that blockbuster was not really far from real life.

Originally, a chip simply transformed skin lines into electronic signals. It was enough to touch a chip with a finger: it would identify its owner. Such dactyloscopic access systems were widely spread all over the world. However, Russian scientists moved further on. They discovered that a chip could not only give an image of a finger, it could also fix its pulsating waves.

How does a lie detector work? They put sensors to various body parts of a human being. Those sensors reflect changes of a person’s physical state: pulse, heartbeat, breath and so on. An appliance like a polygraph uses up to ten channels to obtain information. This equipment requires a lot of space – lie detectors are basically used in separate rooms. On the other hand, about 300 thousand elements of a finger get in contact with a chip, when a person touches it. It is possible to get a pulsating wave from each of them. Here is a comparison: ten channels and one thousand indications of a lie detector against 300 thousand channels and ten million indications of a chip. These exuberant data allow to cut the time to obtain a result: several hours become several minutes.

Let’s say, a suspicious man is going to board a plane. Security guards tell him to put his finger in a device and ask him if he is a terrorist. A chip will not allow such a man to lie. There can be lots of other situations like that. Dactyloscopic chips can be used at nuclear power plants to prevent from any terrorist acts. A chip will be able to identify both the employees of a nuclear power plant, as well as their intentions. In general, it is not requisite to answer any questions at that. It would be enough to check a person’s reaction to them.

A human finger contains a huge volume of information. One has to learn how to take it out. A finger’s pulse allows to obtain various physiological data. Russian medical specialists believe that such results will be even more precise than the ones that a cardiogram can give. All computers will be equipped with such chips in the future. A hole, in which a user will need to put a finger before working with a computer, will be as common as a mouse or a CD-ROM. A user will put a finger in a detector, and a computer will identify, if that user has an access to work, if he or she is in good health for working, and so on and so forth.

It goes without saying that such a development of a personal computer will have a downside to it too. For example, a husband comes home too late after midnight. His wife asks him, what took him so long to return home from work. A man will definitely tell a story of a very long and important meeting at work. A wife will simply ask him to put his finger in a computer and to repeat the whole story again. Nothing would save him.

Doctors discovered that the pulsation of one spots on a human face differs from another one. The pulsation of two spots that are situated close to one another will be different. Russian specialists learned to film the pulse with the help of a small camera and to save the adequate information. Pulsation depends on the physical state of a human being: it differs in the state of calmness, aggression, fright and the like. All those peculiarities will be possible to see on a computer screen. For example, it will be possible to identify a person’s intention at a distance. Let’s say there is a deputy making a speech on television. It would be enough to get him in the viewfinder of a special camera in order to find out, if he is lying or not.

By the way, they used to make a suspect hit a gong in ancient India. It was believed in those times that a lying person would produce louder sounds with a gong. The idea to use detecting appliances appeared at the end of the 19th century in Italy, when Italian criminalist Cesare Lombrozo analyzed and compared the pulse frequency and the blood circulation in a human hand. American scientist John A. Larson invented a polygraph that would react to breathing and blood pressure changes. Then the appliance was developed to react to the electronic activity of skin. Such appliances were not widely used in the USSR.
