FIELD: physics, computer facilities.
SUBSTANCE: invention concerns information protection. The effect is reached in such way that in quality of the password fragment in advance certain colour image is used, fixed chosen by the user which part and transmitted to the server part in the form of hesh-images with in all possible gauges within the given quantities is compared to hesh-images of etalons and at at least one coincidence of hesh-images the password is accepted, and scaling is yielded on quantity multiple to coefficient of scaling by averaging of colours of the nearest reference points taking into account their distances to the scaling point which colour is necessary for spotting.
EFFECT: increase of the use ridentification reliability.
