Abstract

A digital watermark is a secret key dependant signal inserted into digital data (images, sound,texts) and which can be later detected/extracted in order to make an assertion about the data. Technically, the digital watermark is represented as a kind of 'natural' noise. The identification information is encoded into the original unwatermarked data by adding more 'natural' noise and/or rearranging existing noise. The locations for embedding the watermark as well as the value of the watermark are determined by secret elements
