N comprises at least two. The method is characterized in that the N-bit auxiliary data signal is redundantly encoded in the image by at least: changing values of input pixels in a first image location according to a first pattern in order to encode the N-bit auxiliary data signal therein; changing the pattern according to a key to yield a second pattern; and changing values in a second image location according to the second pattern in order to encode the N-bit auxiliary data signal therein.
