Abstract The tasks of personality identification by penscript are solving on a basis of two technologies: “off-line” and “on-line”. Both technologies have their shortcomings. The first technology is realized manually by script experts. It possesses a high work content and has a subjective nature. The second technology is oriented on short texts and possesses a low poor accuracy. The researches state in this area of expertise and results obtained are determine as an actual – the problem of searching of new analysis techniques of arbitrary penscripts received in “on-line” mode, for solving the following problems: identification of personality; detection of deviation scope of individual psychophysical state from its normal state; detection of penscript fragments satisfied the requirement of excessive emotional significance for writer; penscripts research in order to detect the distinctive personality characteristics etc. Thereto in present study the new penscript on-line-analysis method is offered. It based on principles of artificial immune systems functioning. The fundamental difference of immunotechnique of analysis from the traditional ones is the transition from integral estimate of data by the fixed period of their acquisition - to evaluation of on-line data temporal pattern. In order to solve the tasks of penscript analysis it was used the immunological model based on negative selection algorithm. Digitized functions of pen-variation in three-axis which are taking into account the pen-movement in plane of pad and the pressure, removing from the digitizer’s output, are used as initial data for “on-line” analysis. These functions are transforming to sequence of three-dimensional events and are exposed to component-wise processing. That allows to preserve the accuracy of penscript information process presentation and identification result. The proposed method, in comparison with known methods, possesses potentially higher precision of the analysis and significantly expands fields of application of personality identification by penscript systems.
