Provided is a technology of embedding watermark data into an arbitrarily-shaped region by applying a wavelet transform. Prepared are: image data into which the watermark data is to be embedded; a shape map that defines the arbitrarily-shaped region into which the watermark data is to be embedded within the image data; and the watermark data. An SA-DWT processing unit uses the shape map to recognize a given region included in the arbitrarily-shaped region within the image data, and subjects image data in the given region to the wavelet transform. The wavelet transform causes the image data in the arbitrarily-shaped region to be divided into frequency bands, and a watermark data embedding unit embeds the watermark data into a frequency space of the image data generated by the dividing. An SA-IDWT processing unit subjects the resultant to an inverse wavelet transform, and watermark-embedded image data is generated.

A document administration system includes an administration unit, a discrimination information image discriminating unit, and an image forming apparatus which, forms an image on a recording medium in case that the discrimination information image discriminating unit discriminates that the recording medium has the discrimination information image before the image is formed on the recording medium, and forms the image and the discrimination information image based on the discrimination information connected to the image on the recording medium in case that the discrimination information image discriminating unit discriminates that the recording medium does not have the discrimination information image before the image is formed on the recording medium.

A frame generation device has a frame generation section that generates a frame including synchronization information for achieving synchronization with a reception device from among a group including one or more reception devices each of which receives information within the frame, address information indicating an address within the frame for transmitting data, and data transmitted to the reception device included in the group. A group-basis distribution data presence/absence information generation section generates group-basis distribution data presence/absence information indicating whether or not the transmitted data is included in the frame. A synchronization information generation section generates synchronization information including the group-basis distribution data presence/absence information. The frame generation section generates the frame such that the group-basis distribution data presence/absence information is allocated prior to the address information. A central processing unit controls operation of the frame generation section, group-basis distribution data presence/absence information generation section, and synchronization information generation section.

The invention relates to a biometric information detecting apparatus for monitoring a state of a living body based on information constituted by adding an auxiliary data capable of determining a measuring state when biometric information is measured to a biometric state value. A biometric information detecting apparatus of the invention includes a biometric sensor for measuring biometric information for a predetermined time period, A/D conversion means for acquiring a sampling data by subjecting an output of the biometric sensor to A/D conversion, storing means for storing the sampling data, frequency analyzing means for subjecting the sampling data stored to the storing means to a frequency analysis and storing a result of the analysis to the storing portion, biometric state value calculating means for calculating a biometric state value from the result of the frequency analysis stored to the storing means, SN ratio calculating means for calculating an SN ratio from the result of the frequency analysis stored to the storing means, determining means for determining a reliability of the biometric state value based on whether the SN ratio exceeds a predetermined threshold, and measured data preserving means for correlating to store a result of determining the reliability and the biometric state value.
