This paper presents a process able to mark digital pictures with invisible and detectable secret information called the watermarking. This process can be basic of complete cop- right protection system. The process first step consists in producing a secret image. The first part of the secret resides in basic information that forms a binary image. The picture is then frequency modulated. The second part of the secret is precisely the frequencies of the carrier both secret depends on the identity of the copyrights owner and on the original picture contents. The obtained picture is called stamp. The second step consisting of modulating the amplitude of the stamp according to a masking criterion stemming from model of human perception. That to theoretical criterion is supposed not to match. This is followed by the adaptation of the level of the stamp at that place. The so formed watermark is then added to the to ensure its protection. That watermarking method allows the detection of watermarked pictures in a stream of digital images, only with the knowledge of picture owner’s secret.
