FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering and can be used to protect a user from identifying an information system user by handwriting information input from a manipulator. User identification protection system comprises a user identification protection device, a keyboard, a computer and an information display device, wherein the keyboard is connected to the computer through the user identification protection device. Coordinate signals coming from the manipulator are randomly distorted using the protection device before inputting said signals into the computer. Signals of keystrokes of the manipulator coming from the manipulator are delayed using the protection device for random time intervals before input of the said signals into the computer.
EFFECT: possibility of hiding user’s handwriting by distorting cursor and scroll wheel trajectories and introducing delays during button actuation, which provides effective protection of the user from personal identification by handwriting input using a mouse or a manipulator with a similar function.
