FIELD: information technologies. ^ SUBSTANCE: video subject to protection is desynchronised, and therefore, one or more videos are created with inserted digital distinction marks. In one realisation, the video to be protected, is exposed to time desynchronisation and space desynchronisation. Copy of video is created with distinction marks as modified by means of time and space desynchronisation. ^ EFFECT: improved resistance to collective attacks of culprits, for use when inserting distinction marks into digital video to be protected. ^ 20 cl, 17 dwg, 2 tbl |
