Robust hash controlled watermark embedding.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
The process of embedding a digital watermark into a media file is often complex and time consuming as multiple operations take place within the process to ensure a high level of perceived quality of the marked copy and a high robustness of the embedded watermark. So far, improvements of the watermarking algorithms also lead to a higher complexity of the embedding process: State of the art watermarking algorithms require spectral transformation operations as well as windowing and perceptual models for masking the embedded watermark. Our new concept is to set up a collection of already computed watermarking signals and mix them with the cover signal for fast and simple embedding. To ensure that the watermark signal is well suited for the embedding position with respect to masking, we suggest using robust hash technology.
