Abstract: The present invention relates to a computer system and to a method for encoding of information into a representation comprising a plurality of segments, the order of the segments in the representation being irrelevant for a rendering of the representation, the method comprising the steps of: identification of the segments, permutation of the segments to encode the information.

Abstract: Disclosed are a method, apparatus, and program for providing authentication of a rendered multimedia realization. A renderer and a watermark generator are integrated wherein the renderer receives a symbolic stream, e.g. in the case of a text-to-speech system a text, and generates a realization, e.g. an audio signal representing a spoken version of the text. An identification is embedded into the signal by the watermark generator using standard steganographic methods. Such a serial integration of renderer and watermark generator is applicable to all known renderers and watermarking techniques. The mechanism enables inheritance of originality of the original representation or realization to the rendered realization.
