Abstract:
1. A method for applying digital watermarking image data or digital watermarking audio data to an unlabeled digital image, audio, or video data sample, said method including the steps of: a) inputting a set of unlabeled digital data and a set of digital watermark data; b) formatting the unlabeled digital data into a format suitable for orthogonal transformation; c) performing an orthogonal transformation on the formatted unlabeled data to produce a set of unlabeled data transform coefficients; d) formatting the digital watermark data into a format suitable for orthogonal transformation; e) performing an orthogonal transformation on the formatted watermark data to produce a set of watermark data transform coefficients; f) for each watermark data transform coefficient, allocating an unlabeled data transform coefficient to be replaced and replacing the respective unlabeled data transform coefficients to produce a labeled set of data transform coefficients; g) storing the locations into which watermark data transform coefficients were encoded in the set of labeled data transform coefficients to generate a unique key for future decoding of the watermark data; h) performing an inverse orthogonal transformation on the labeled data transform coefficients to convert them into a set of labeled digital data having a form resembling the original unlabeled digital data.
