摘要： Methods, devices and computer program products allow embedding and detection of watermarks into and from a multimedia content. One watermark embedding method includes selecting a content segment that lacks inherent features for embedding of watermarks without producing perceptible artifacts, and obtaining a first dither pattern corresponding to a first watermark symbol of a watermark symbol alphabet, where each symbol is associated with a particular dither pattern. Further, each particular dither pattern, upon combination with the multimedia content segment that lacks inherent features, produces a composite content segment without perceptible artifacts. By combining the first dither pattern with the multimedia content segment that lacks inherent features, a first composite content segment with the first embedded watermark symbol is produced. The detection of watermarks messages can be carried out quickly by examining a small portions of the multimedia because even the featureless content segments include embedded watermarks.

摘要： The invention relates to a method for generating and authenticating image information data from information data, which image information data can be printed in a forgery-proof manner, comprising the following steps: encoding the information data into a form of binary information pixels, wherein the binary information pixels are arranged in a grid-like manner in accordance with a first grid in respective first grid regions (R1) within an image region (R0); dividing the respective first grid regions (R1) into respective second grid regions (R2) by means of a second grid; determining a respective information field (Ixy) of the respective second grid regions (R2) of the respective first grid region (R1) in accordance with a first association rule and determining the other second grid regions (R2) as faulty fields (Sxy); associating with the respective information field (Ixy), in dependence on the value of the information pixel, a first information color value (IF1) for a value 1 and a second information color value (IF0) for a value 0; determining and associating with the respective fault fields (Sxy) a respective fault color value in accordance with a fault color value association rule; and storing the second grid regions with the respective information color values (IF1, IF0) and fault color values as printable image information data.
