A method for inserting data, including a predetermined number of symbols, into an image sequence of at least one image comprising a predetermined number of lines each containing a predetermined number of pixels, comprising the steps of generating a set of functions with a comb-shaped spectrum inserted in an image sequence spectrum and including a respective function for each symbol of the information to be inserted, phase shifting each function of the set of functions by a value representing a respective symbol of the data to be inserted, superimposing the phase-shifted functions, and combining the pixels of the image sequence with a result obtained by superimposing phase-shifted functions.
