    Abstract: A method of hiding message information in media information in a frequency space. A high resistance to removal and alteration of hidden message is given. Even when signal processing is executed by using a frequency filter, the hidden message information is continuously maintained effectively. The frequency spectra (f1 and f2) of the medium information (M) and message information (m) are found by frequency-converting the information (m) and the information (M) in order to hide the message information (m) in media information (M). Then an area containing a characteristic frequency component indicating the feature of the message information (m) in a real space is extracted from the frequency spectrum (f2) of the message information (m) as a basic area (B). Then a frequency spectrum (f3) is generated as intermediate information by making n copies of the basic area (B), dispersedly arranging the copies in the frequency space and making the other frequency components zero. Lastly, the message information (m) is hidden in the medium information (M) by executing operation based on the frequency spectrum (f3) and medium information (M).

    Abstract translation: 本发明的目的是提供一种用于将附加信息嵌入到视频电影中而不对视频电影的压缩效率基本上具有影响并且也不会显着降低图像质量的方法。 ÄCONSTITUTIONÜ在视频电影的帧中指定至少一个嵌入区域用于嵌入信息，并且通过参考要嵌入的数据的内容的嵌入规则来确定与要嵌入的信息相对应的嵌入区域的帧间预测的类型 使其对应于嵌入区域的帧间预测的类型。 期望存在嵌入区域的帧是双向预测编码帧。

    Abstract: UN OBJETO DE LA PRESENTE INVENCION ES EL DE PROPORCIONAR UN PROCEDIMIENTO PARA EMPOTRAR INFORMACION ADICIONAL EN UNA PELICULA DE VIDEO SIN QUE TENGA PRACTICAMENTE INFLUENCIA ALGUNA EN LA EFICIENCIA DE COMPRESION DE LA PELICULA DE VIDEO Y AL MISMO TIEMPO SIN PROVOCAR UNA DEGRADACION SUSTANCIAL DE LA CALIDAD DE LA IMAGEN. SE ESPECIFICA AL MENOS UNA REGION DE EMPOTRAMIENTO EN EL ENCUADRE DE LA PELICULA DE VIDEO PARA EMPOTRAR INFORMACION Y SE DETERMINA UN TIPO DE PREDICCION INTER - ENCUADRES DE LA REGION DE EMPOTRAMIENTO, EN CORRESPONDENCIA CON LA INFORMACION QUE DEBE EMPOTRARSE, HACIENDO REFERENCIA A UNA REGLA DE EMPOTRAMIENTO POR LA CUAL EL CONTENIDO DE DATOS QUE DEBEN EMPOTRARSE SE HACE QUE CORRESPONDA AL TIEMPO DE PREDICCION INTER - ENCUADRES DE LA REGION DE EMPOTRAMIENTO. ES CONVENIENTE QUE EL ENCUADRE EN EL QUE SE ENCUENTRA LA REGION DE EMPOTRAMIENTO SEA UN ENCUADRE CODIFICADO - PREDICTIVO BIDIRECCIONALMENTE.

    Abstract: An objective of the present invention is to provide a method for embedding additional information into a video movie without substantially having an influence on the compression efficiency of the video movie and also without substantially causing degradation of the picture quality. ÄCONSTITUTIONÜ Specify at least one embedding region in the frame of the video movie for embedding information, and determine a type of interframe prediction of the embedding region in correspondence with information to be embedded by referring to an embedding rule where a content of data to be embedded is caused to correspond to the type of interframe prediction of the embedding region. It is desirable that the frame in which the embedding region exists is a bidirectionally predictive-coded frame.
