Abstract

The present relates to a method for watermarking a set of data, said method comprising the acts of partitioning the set of data into a plurality of layers and transforming a first layer into a first watermarked layer with a watermarking function using a watermarking key and a watermark, wherein the watermark is generated from a hash function applied to a second watermarked layer.
