Abstract

A method of detecting and extracting a watermark (digital watermarking) in a digital signal. The watermark is composed by the repetition of elementary components of a load to be transmitted. At least one repetition of an elementary component in the digital signal is detected. At least one quality attribute is assigned to each repetition of at least one elementary component. The repetitions of an elementary component are sorted according to a function of the quality attributes of these repetitions. Certain repetitions, dubbed individualities, of an elementary component are selected. The selected repetitions are fused.
