An enhanced security protection in data duplication using a shared storage area is provided. Specifically, an information processing apparatus, in which one or more applications operate, includes a copy-operation monitoring portion that acquires copy data that the copy source application issues an instruction to copy to a general-purpose shared memory, sets a lifetime interpreted from an operation pattern via an input device for the copy data, and then stores the copy data in a storage area; a display portion that displays, on a display, a paste candidate selected from one or more items of copy data stored in the storage area; a paste-operation monitoring portion that transfers the paste candidate read from the storage area to the paste destination application in response to a confirmation operation via the input device; and an erasing portion that erases, from the storage area, copy data that has become unpermitted to remain because the lifetime has expired.
