Abstract: An information processing apparatus comprising a coordinate input unit for inputting coordinate data series, a recognition unit for recognizing a character based on the coordinate data series inputted, and a page/note management unit for managing a data aggregate of the character recognized as a page, receiving a search condition from a user, and managing one or more page aggregates hit by the condition as notes.

Abstract: [Object] To improve operability of an information processing apparatus. [Solving Means] It includes a coordinate input unit for inputting coordinate data series; a recognition unit for recognizing a character based on the coordinate data series inputted; a page/note management unit for managing a data aggregate of the character recognized as a page, receiving a search condition from a user, and managing one or more page aggregates hit by the condition as notes.

Abstract: In order to prevent software sold by a software sale server to a user and downloaded to a computer of the user from being copied and used illegally, the software server is informed of apparatus information unique to the computer and a user ID assigned to the user when the computer of the user is sold to the user. When the user purchases software from the software server, the software server saves the name and version of the software, associating the name and the version with the user ID and the apparatus information. When the user activates the software for the first time, the computer transmits the user ID, the apparatus information, the software name and the software version to the software server to be collated with their respective counterparts, which were saved before. If a result of collation indicates that the pieces of information match their counterparts, a license key for activating the software is transmitted to the computer of the user.

Abstract: A first client device is allowed to run software that a second client device owned by the same user has been allowed to run. At that time, a user ID of the user, a device ID of the second client device, and a software ID of the software, registered in association with each other, are deleted from a database server, and the software ID of the software is registered in association with the user ID of the user and the device ID of the first client device. When it has been verified that the software ID is registered in association with the user ID of the user and the device ID of the first client device, a license key is issued to the first client device.
