摘要： Information embedding is performed by extracting vertices constituting a polygon from vector data, and changing a number of points that exist on sides of the polygon based on embedment information. Further, information reading is performed by extracting points existing on the sides of the polygon from the embedment information and embedded vector data, and by reading the embedment information according to a predetermined rule.

摘要： A digital image signal is divided into blocks. Each of the divided blocks is subjected to orthogonal transformation. As a result, the divided blocks are transformed into several frequency components. One or more frequency components are selected in accordance with a characteristic amount that is extracted from the several frequency components. Values of the selected frequency components are operated under a predetermined rule in accordance with an embedment signal that is generated from embedment information.

摘要： A bit stream is decoded to generate first quantized DCT-coefficients. The first quantized DCT-coefficients are inversely quantized using a first quantization table, thereby generating DCT-coefficients. The resulting DCT-coefficients are quantized using a second quantization table, thereby generating second quantized DCT-coefficients. Elements in the second quantization table are smaller in value than those in the first quantization table. Predetermined additional information is embedded into the second quantized DCT-coefficients. The second quantized DCT-coefficients having the additional information embedded therein are encoded to produce a bit stream having the additional information embedded therein. The second quantization table is set to be smaller in value than the first quantization table.

摘要： An electronic watermark technique which allows precise detection of electronic watermark information from image having any size is provided. In an electronic watermark embedding device 100, an image size obtaining section 101 obtains an image size. A block size determination section 102 defines an area formed of a plurality of pixels as a block, and calculates a size of the block based on the image size. An embedding section 103 embeds the electronic watermark in units of the block of the calculated size. In an electronic watermark detection device 700, an image size obtaining section 701 obtains an image size of image data in which the electronic watermark is embedded. A detection filter producing section 702 calculates a size of a detection filter based on the image size. A detection section 703 detects the electronic watermark using correlation between the detection filter having the calculated size and the image data.
