Configuring a paper medium information encrypting system to include a digital image acquiring unit acquiring a digital image of information by capturing an image of a paper medium, an encryption area designating unit designating an encryption target partial area in the digital image, an image converting unit converting the image of the partial area into a processed image on the basis of an encryption key, a pixel value converting unit generating a converted image having a regularity at a spaced interval, used for specifying a position of the partial area when performing decryption, by regularly converting pixel values of the processed image, and an output unit outputting an encrypted image containing the converted image, wherein the encryption area designating unit designates, as the encryption target partial area, an area specified by an area designating information for specifying the area on the digital image.

Paper medium information encrypting system, decrypting system, program and method

An apparatus for managing shared resources used in common by a plurality of computer systems connected together through a network, wherein an executable unit on a particular computer having the shared resources is arranged being divided into a first executable unit which requests the input/output processing unit in the resource managing unit that directly manages the shared resources to execute the process for inputting/outputting the shared resources in response to optional executable units, and a second executable unit which, by using an identifier for identifying the first executable unit, requests the locking processing unit in the resource managing unit to execute the process for locking the shared resources in response to other optional executable units substituting for said first executable unit. The invention further provides a method of managing system resources wherein the second executable unit in the apparatus for managing system resources constituted as described above executes the process for locking the shared resources to substitute for the process of the first executable unit, by using the identifier that identifies the process of the first executable unit.
