Abstract
1. Способ идентификации личности по рукописному паролю, состоящий в том, что для прохождения процедуры идентификации, подписант воспроизводит на графическом планшете рукописное слово-пароль, параллельно преобразуются в цифровую форму колебания пера на плоскости, давление, оказываемое кончиком пера на поверхность планшета, изменения угла наклона пера относительно плоскости дигитайзера, а также поворот пера относительно собственной оси, масштабируют каждую функцию этой подписи с последующим разбиением полученных функций на фрагменты по нескольким признакам, вычисляют дифференциальные и интегральные параметры по полным реализациям упомянутых функций и их фрагментам, а также вычисляют пары коэффициентов корреляции между соответственно дифференциальными и интегральными параметрами полных реализации и их фрагментов упомянутых функций, отличающийся тем, что принимают идентификационное решение сравнением вычисленных упомянутых параметров и пар коэффициентов корреляции с их эталонными значениями, используя вероятностный метод распознавания, полученную на последнем шаге гипотезу с наибольшей апостериорной вероятностью подвергают повторной верификации, сравнивают меру близости параметров предъявленного образца подписи (пароля) с эталонными параметрами. ! 2. Способ по п.1, отличающийся тем, что осуществляют аутентификацию личности, используя в качестве идентификатора пользователя уникальный код, хранимый в памяти микросхемы светового пера (указательного устройства).1. A method of identifying a person using a handwritten password, which consists in the fact that the signer reproduces a handwritten word-password on a graphic tablet in order to go through the identification procedure, and the pen vibrates on the plane digitally, the pressure exerted by the tip of the pen on the tablet surface, angle changes the inclination of the pen relative to the digitizer plane, as well as the rotation of the pen relative to its own axis, scale each function of this signature with the subsequent division of the obtained functions into fragments for several features, calculate differential and integral parameters for the full implementations of the mentioned functions and their fragments, and also calculate pairs of correlation coefficients between respectively differential and integral parameters of the complete implementations and their fragments of the mentioned functions, characterized in that they make an identification decision by comparing the calculated mentioned parameters and pairs of correlation coefficients with their reference values using the probabilistic recognition method obtained at the last Step hypothesis with the highest a posteriori probability is subjected to re-verification, comparing the measure of closeness parameter brought against the sample signature (password) with the reference parameters. ! 2. The method according to claim 1, characterized in that the authentication is carried out using a unique code stored in the memory of the light pen chip (pointing device) as a user identifier.
