摘要： Regularity information such as time codes embedded preliminarily through an electronic watermark is detected from a predetermined number of pieces of continuous frame data of video content through the electronic watermark. In the case where the electronic watermark is not detected from the predetermined number of pieces of continuous frame data, a non-detection count is calculated, and falsification of the predetermined number of pieces of frame data is determined on the basis of the detected regularity information and the non-detection count. Accordingly, falsification such as deletion, addition, and replacement of video content is detected with high accuracy using the electronic watermark.

摘要： The problem to be solved is to allow anyone other than the contents license owner to acquire a right usage opportunity of contents while the fraud in the contents can be detected. To solve this problem, a contents ID, distribution media information specifying the distribution media of the contents, and identification information containing distribution period information specifying the distribution period of the contents are attached to the contents body When a contents acceptance module 140 receives the contents data, an acquisition pattern recognition unit 142 recognizes the acquisition pattern information of the contents data. A identification information extraction module 154 of a contents validity determination module 150 extracts identification information from the contents data. A validity determination unit 153 compares the condition specified by this identification information with the contents acquisition media and the acquisition period indicated by the acquisition pattern information and if the acquisition pattern information satisfies the condition specified by the identification information, the contents data is stored in the contents-for-distribution file 126. Additionally, if the contents are determined to be illegal a deletion request is sent to the requestor.

摘要： An intended image data structure is assumed to have a color information storing region and a pixel information storing region as its components. First, consider that the color information storing region within the image data structure is divided into a plurality of subregions, and a corresponding bit value is defined for each of the subregions. Next, an index number stored for each of pixels within the pixel information storing region is changed to an index number belonging to a subregion corresponding to a bit value of information to be embedded. In this way, one bit or more of information can be embedded for each pixel. Thus, a large amount of information can be embedded into a small-size image composed of simple shapes and having a small number of colors without degrading the image quality, and the information can be extracted from the image in which it has been embedded.
