20080313702 | INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND RECORDING MEDIUM - An information processing system which includes a compound content generation apparatus and a compound content consumption apparatus and processes a plurality of protected contents, the compound content generation apparatus comprising a compound content generation unit configured to generate a compound content from a plurality of protected contents, and the compound content consumption apparatus comprising a composite policy generation unit configured to generate a composite policy by obtaining an intersection of condition values of policies set for the respective protected contents contained in the compound content, and a compound content consumption unit configured to consume the compound content in accordance with the composite policy. | 12-18-2008 |
20090089661 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - An information processing apparatus comprises an input unit adapted to input forming information, a plurality of objects and usage conditions for the plurality of objects, the usage conditions including layout information that is generated from the forming information; a control unit adapted to control usage permission of the forming information and the plurality of objects based on the usage conditions; and an output unit adapted to lay out and output the permitted plurality of objects in accordance with the permitted forming information. | 04-02-2009 |
20100023746 | INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, AND INFORMATION PROCESSING METHOD - This invention prevents confidential information included in information contents from leaking from an external apparatus when the external apparatus executes a layout process and print process of the information contents. An information processing system of this invention includes an information contents converter ( | 01-28-2010 |
20100135526 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - This invention provides a technique of preventing determination of image alteration when digital image data has undergone, e.g., rotation without any substantial change in contents. To do this, an area separation processing unit separates image data into areas. For each of the separated areas, an area feature value calculator calculates an area feature value independent of the coordinate information of the image. An area order sorter sorts the separated areas in accordance with the calculated area feature values. A validation data generation processing unit generates validation data based on the sort result. | 06-03-2010 |
20110103698 | INFORMATION PROCESSING APPARATUS AND METHOD OF CONTROLLING THE SAME - In verification of image data of a captured image as to whether it is original one, the verification is possible even for image data subjected to a peripheral illumination correction or an exposure correction. An order information calculation unit selects a pixel set including two or more pixels based on pixel values and information on an image space of image data of a captured image, and calculates an order of magnitude between pixels in the selected pixel set. A verification data producing unit generates verification data used in verification of whether the image data has not been tampered with, based on the calculated order of magnitude. An image output unit outputs the image data and the verification data. | 05-05-2011 |
20110199501 | IMAGE INPUT APPARATUS, IMAGE VERIFICATION APPARATUS, AND CONTROL METHODS THEREFOR - The invention enables a verifier to easily confirm that the image data was captured in the multiple exposure mode, and also to easily confirm which area in the image captured in the multiple exposure mode was greatly affected by multiple exposure. An image generating unit generates exposure image data pieces by exposing an image sensor a plurality of times. An image composition unit combines exposure image data pieces to generate a single piece of composite image data. A reference image generating unit generates reference image data composed of data pieces for distinguishing pixel positions at which the exposure amount exceeds a threshold from the other pixel positions. A verification data generating unit generates verification data for determining whether alteration has been made from the composite image data and the reference image data to output a single file. | 08-18-2011 |
20110271121 | DATA PROCESSING APPARATUS, DATA PROCESSING SYSTEM, AND METHOD FOR CONTROLLING THE SAME - A data processing apparatus acquires content, generates an encryption key by using an initial value written in an unwritten memory block in a write-once recording medium, encrypts the content by using the encryption key, and writes to the write-once recording medium the encrypted content and an address table for identifying the memory block storing the initial value used for generating the encryption key. | 11-03-2011 |
20120212766 | PRINT PROCESSING APPARATUS AND METHOD FOR CONTROLLING THE SAME - A print processing apparatus includes a plurality of processing units configured to deal with a plurality of printing processes, a storing unit configured to store a table in which processing start conditions in the plurality of printing processes are defined based on a distance between a user and the print processing apparatus, an acquisition unit configured to acquire a distance between a position of the user who has issued a print job and the print processing apparatus, and a control unit configured to control the plurality of processing units for the print job based on the table and the acquired distance. | 08-23-2012 |
