Abstract
A method for marking a series of images such as a film for identification. A copy of the film is associated with a series of pseudorandom values that correspond to fields of a virtual grid covering an image. A visible mark is put into the field corresponding to the first pseudo-random value in M consecutive images followed by a number N of unmarked images (N) before repeating this using the next pseudo-random value. The visible marks are advantageously quite small so as to keep user disturbance to a minimum, but they may also be quite visible. Also provided is a marking apparatus.
