Abstract: To support a shopper to perform self-service shopping by using an electronic shelf label (ESL) while looking at actual items displayed in a store and to expand the functions of the electronic shelf label (ESL) to enable the linkage with other data processing systems expansively. A shopper uses a mobile processing device (typically, a cell phone owned by the shopper) in a store. The functions necessary to obtain contents from the electronic shelf label (ESL) are obtained by introducing an application program into the shopper's own cell phone, by which it is expected that the shopper is able to easily enjoy shopping. When photographing the electronic shelf label (ESL), the contents associated with items are encoded (the price display automatically changes to a barcode) and then decoded.

Abstract: To delegate authority for cryptographic communication without increasing the risk of leaking a device key. A system and method including a first communication apparatus and a managing apparatus allowing the first communication apparatus to perform cryptographic communication with an external at least one second communication apparatus. The managing apparatus includes: storing a first device key shared with the second communication apparatus; generating a computation by passing the first device key read from the stored keys to a keyed one-way function, to generate a computed result as a second device key; and outputting the second device key and a key of the one-way function to the first communication apparatus. The first communication apparatus transmits a key of a one-way function to the second communication apparatus causing the second communication apparatus to perform a computation which generates a second device key, and which performs a cryptographic communication with a second communication apparatus.

Abstract: A method of manufacturing a physical medium configured to store data. A layout design of visible and invisible information to be printed in a book with visible and invisible ink, respectively, is generated. The visible information includes an article. The invisible information includes a URL of an address of a web server at which additional information associated with the article is located. Print data of the visible and invisible information based on the generated layout design of the visible and invisible information are generated. The generated print data of the visible and invisible information are stored on the physical medium. A book containing the article in visible ink and the invisible information in invisible ink is produced. A cellular phone is used to obtain the additional information by identifying the URL via illuminating and photographing the invisible information in the book using a light-emitting element in the cellular phone.

Abstract: To provide lossless embedding of a visible watermark in compressed motion picture data. The present invention includes a quantization/dequantization operation part 10 for dequantizing motion picture data that has been subjected to compression including frequency transformation and quantization, and a watermark embedding/removing operation part 30 for generating and embedding a pattern of a visible watermark corresponding to a motion compensated prediction in motion picture data dequantized by the quantization/dequantization operation part 10. The quantization/dequantization operation part 10 quantizes motion picture data with a watermark embedded by the watermark embedding/removing operation part 30.

Abstract: An image of a sample print printed to obtain parameters is picked up by using “a parameter obtaining device” that meets the standards of an instrument for the invention of “the electronic scrap system.” Then, the picked-up image is captured by a DTP system, and color data of a needed position are imported to a parameter DB. Thereby, parameters for simulation to be used in an invisible code printing support system can be easily inputted. Use of this method eliminates the necessity of figuring out parameters through experiments and the like, and of inputting these parameters as numerical values. In addition, since this method uses a physical medium and inks to be actually used, as they are, their optical characteristics, an influence of a blue component of invisible light emitted from an ultraviolet LED, and the like can be inputted all together as a picked-up image.

Abstract: Watermark data that indicate additional information, such as copyright information, are optimized in accordance with the contents of object data, and the watermark data is embedded in image data. An image divider 200 divides image data Vi into image blocks Iij, and corresponds a selected basic pattern Phij with each of the image blocks Iij. Orthogonal transformation units 24 and 202 generate DFT coefficients I?ij and P?hij, and power element calculators 208 and 264 generate power elements I?ij and P?ij. A basic pattern adjustment unit 26 adjusts the coefficient of P?hij to generate P?hij1 to P?hijn. A watermark pattern generator 28 calculates variations before and after P?hij1 to P?hijn are embedded in I?ij, and selects, from P?hij1 to P?hijn, P??hij1 to P??hij1 that provide variations equal to or smaller than the threshold value e. Then, the watermark pattern generator 28 selects, as a watermark pattern P?ij, the pattern that is most easily detectable, and a pattern embedding unit 204 that adds P?ij to I?ij.

Abstract: It is one object of the present invention to prevent embedded verification information from being lost even when a quantization process is performed after verification information has been embedded. A pre-embedding portion 32 converts a image data value so that quantized values not changing by error introduced through the embedding process. A hash value calculator 300 calculates a hash value using image data and key information, and a hash value embedding portion 302 embeds the hash value in the image data. An output format converter 304 quantizes the image data in which the hash value is embedded, and generates JPEG data.

Abstract: The present invention provides methods, apparatus and systems for embedding and detecting an electronic watermark without requiring signals for geometric compensation. A particular embodiment uses a periodic pattern with repetition as an embedded pattern itself, which has information embedded as an electronic watermark, and observes the change of its period upon detection to calculate the scaling factor. When detecting the electronic watermark, the scaling factor of images is calculated from digital data that underwent the scaling processing, and then the processing to detect the electronic watermark is performed based on the obtained scaling factor.

Abstract: The present invention is directed to the detection of what part of an image alteration was added to by embedding an electronic watermark in the image. More particularly, embedding part 30 renders as pairs two each of DCT blocks of luminance component Y of an image, randomly selects, by using a random number, mutually corresponding DCT coefficients from each DCT block contained in the pairs, and manipulates so that the relationship among these DCT coefficients represent data according to a certain rule, and then embeds the data. If alteration is added to this image, the DCT coefficients contained in the pairs in the altered part do not observe the above rule and represent different values from the original data. Extraction part 40 extracts data from the image, and makes decision by majority to estimate the initially embedded data to detect and display the pairs from which different data form the estimated data was extracted as those to which alteration was added.
