Abstract: Each node connected to an ad hoc network receives route information from an adjacent node. Each node obtains quality information indicating quality of a route indicated by the route information with respect to the received route information. Each node determines whether a plurality of route information items whose packet destination nodes are the same are received at a predetermined frequency. When it is determined that a plurality of route information items whose packet destination nodes are the same are received, each node compares quality information items of the plurality of received route information items, and selects a route information item corresponding to a quality information item indicating a highest quality as a comparison result. Each node relays the selected route information item to an adjacent node.

Abstract: A portable storage medium adapter, which is connected to a computer to store data received from the computer in a portable storage medium, includes a holding part that detachably holds the portable storage medium, a detecting part that detects an unloading operation of the portable storage medium by a user, and a disablement executing part that executes a disabling process to disable external access to the data stored in the portable storage medium at a time when the unloading operation is detected in the detecting part.

Abstract: A computer-implemented method that enables an operation relative to a removable storage medium connected with a computer includes, obtaining an erasing flag to be set to the removable storage medium on the basis of a predetermined rule when the removable storage medium being connected, obtaining a connection time when the removable storage medium is connected, and identifying whether a program being activated on the computer is an erasing program for erasing data stored in the removable storage medium. The computer-implemented method enables concealing, upon the erasing flag is being on and the program being activated being other than the erasing program, data to be erased classified on the basis of the connection time included in the data stored in the removable storage medium.

Abstract: A device driver includes an access permitted directory storage unit and an access-permission determining unit. The access-permitted directory storage unit stores as an access-permitted directory an activation directory for a process that is allowed to access an S memory (private memory). The access-permission determining unit checks whether an activation directory for a process that has requested for access to the S memory matches the access-permitted directory. Based on the result, the access-permission determining unit determines whether to accept the access request.
