摘要:
The CPU in the processing unit of an external storage device transmits data between an information processing device and a storage medium, determines whether or not the information processing device can access the storage medium of the external storage device, decrypts data encrypted in the storage medium, etc. using a program loaded into RAM through an interface or a read/write unit. Changing the data loaded into the RAM efficiently and flexibly guarantees the security of the data stored on the storage medium.

A program ID is provided for each authoring program, the program ID of the authoring program is copied to the program ID whenever the authoring program processes contents, and contents ID are newly generated and provided also for each contents. Thereby, the management of an authoring program or contents such as assuring of copyright, preventing of alteration, or maintaining of security is simplified.

A security system for protecting information stored in portable storage media by checking identifiers assigned to each medium, system, and terminal. Medium IDs are identifiers written by manufacturers of the storage media. System IDs, or corporate IDs, are assigned to enterprise-wide computer systems each consisting of a host computer and terminals. Terminal IDs are affixed to the respective terminals. Data is stored in the media in encrypted form. The security system checks the validity of the medium ID, system ID, and terminal ID, manages before allowing the user to perform any data access, thus protecting the contents from unauthorized access. The security system also writes permission data into each storage medium to manage the decryption of encrypted data stored therein. The permission data contains an encrypted key which is necessary for decrypting the data, and the key can be decoded only with a valid medium ID and unit ID, thus protecting the data in the medium against any attempt to decrypt it with unqualified equipment.

In a communication terminal device, in a case where the arrangement of the windows is changed in a list screen, an overhead screen is initially displayed, in which the list screen is overviewed, and the arrangement of the windows is subsequently changed in the overhead screen, and a magnified screen (original screen) of the overhead screen, in which the arrangement of the windows has been changed, is displayed last, as described in the foregoing. By displaying a magnified image, it is possible to make windows better visible in a small display area of a mobile phone. Also, in a case where a window exists that cannot be displayed in a magnified screen, by displaying an overhead screen, it becomes possible for a user to recognize a fact that a window that cannot be displayed exists in a magnified screen, and also recognize a position of the window.

It is intended to enable enlarging or reducing a screen with a simple operation. A mobile phone 1 includes a touch panel 11 that displays a screen and receives a predetermined input, a detection unit 12 that detects a start point and an end point of a physical touch on the touch panel 11, and a display control unit 13 that calculates a moving direction of the touch on the basis of the detection result, enlarges the screen displayed on the touch panel 11 when the moving direction is in a predetermined first range, and reduces the screen when the moving direction is in a predetermined second range different from the first range.

An information-processing device comprises: a display control that controls display positions of first and second information images in a display area of a display means for displaying an image, instructions are received for causing the first information image to move in a given direction. A display control executes a first process that, during a period in which the instruction is received, causes the first information image to move and a second process that, in a case where the first information image comes into contact with the second information image as a result of the movement caused by the first process and is further moved after the contact, causes the second information image to move in a direction different from the direction of movement of the first information image, such that the second information image does not overlap the first information image.
摘要:
A content distribution system according to the present invention comprises a content distribution management device and a communication terminal. The content distribution management device includes a storage unit that stores one or a plurality of addresses; a receiving unit that receives content data addressed to a communication terminal; a determination unit that determines whether or not the address of the origin of the received content data is an address that is stored in the storage unit; and a sending unit that, in the case where the determination unit has determined that the address of the origin of the received content data is an address that is stored in the storage unit, sends the content data and parameters specifying the format in which content is to be displayed by the communication terminal to which the content data is addressed to a communication terminal. The communication terminal includes a receiving unit that receives parameters and content data from the content distribution management device; and a content display control unit that displays the received content data and controls the display format thereof in accordance with the received parameters.
摘要:
Provided is a setup that allows a user to view, after the fact, the circumstances of communication within a virtual space with other users who were previously present at the same place as the user. When a user designates a previous day and time, the circumstances in the virtual space for said designated day and time are reproduced. When the avatar of the user appears and is caused to speak in the reproduced virtual space, the history content is changed as though the speech actually occurred in the virtual space on that day and time. In this way, the user can read, alter the fact, the circumstances of communication within a virtual space with other users who were previously present at the same place as the user.
