Title:
DIGITAL SIGNAL WATERMARKING DETECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO2005096614
Kind Code:
A3
Abstract:
The invention relates to a method of detecting the watermarking of a digital signal (S') that has been watermarked with the application of a watermarking function to pre-determined attributes of the signal. The inventive method comprises the application of a watermarking key extraction function in order to: select (50) the watermarked attributes and to locate the co-ordinates thereof in a reference partition comprising as many zones (Z
