Disclosed are methods and systems for embedding watermarks in information signals to obtain a watermarked information signal. The method of embedding a watermark comprises the steps of determining a predetermined first property of a first part of the information signal, said predetermined first property being indicative of whether at least a predetermined first part of the watermark signal is detectable in the first part of the information signal; embedding the at least first part of the watermark in the first part of the information signal to obtain the watermarked information signal, if the at least first part of the watermark signal is determined not to be detectable in the first part of the information signal; otherwise generating the watermarked information signal to include the first part of the information signal.
