APPARATUS FOR EMBEDDING WATERMARK INTO INFORMATION REPRESENTATION, DETECTOR FOR DETECTING WATERMARK IN INFORMATION REPRESENTATION, METHOD AND COMPUTER PROGRAM

摘要

FIELD: information technology.SUBSTANCE: apparatus for embedding a watermark to be embedded into an input information representation includes: an embedding parameter determiner; a watermark adder; a watermark information detector; where the apparatus for embedding is capable of selecting the number of applications of a derivation function to an initial value to obtain an embedding parameter, where the embedding parameter determiner is capable of applying an index parameter and determining, depending on the index parameter, how many times the derivation function should be applied to a predetermined initial value to obtain the embedding parameter.EFFECT: facilitating the embedding of a watermark into an information representation.23 cl, 16 dwg
