Handwriting is a field of knowledge that is in demand mainly in forensic science. The main task of handwriting specialists is to compare samples of records in order to identify their authors. But, as you know, in recent decades, office work and correspondence have almost completely switched to electronic format, which significantly complicated the work of forensic specialists.
However, a way out has been found. A group of mathematicians from Kursk University, headed by Leonid Kryzhevich, has developed a unique program for identifying people using a keyboard. The determination accuracy exceeds 95%.
As the initial data, the researchers used the algorithm of work of several tens of muscles involved in the typing process. At the same time, such parameters as the force of the blow, the time to find the desired key and the time of holding it were taken into account. As it turned out, all these moments last only a few microseconds and are unique to each person.
The program, developed by the Kursk mathematicians, is based on the theory of probability and statistics. It makes it possible to identify the user, save information about him and, if necessary, perform authentication - confirmation of his identity. To do this, it will be enough to type no more than 6 characters.
The unique program will certainly be in demand at sensitive facilities, when entering Internet passwords and dialing a PIN code at ATMs.
