1. An information processing apparatus in which one or more applications operate, the apparatus comprising: a copy-operation monitoring portion that acquires copy data that a copy source application issues an instruction to copy from a document 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 a 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 whose lifetime has expired, wherein the copy-operation monitoring portion determines the lifetime, in cooperation with a content analysis engine that analyzes the content of the obtained copy data, depending on a security level of the copy data that is determined by the content analysis performed by the content analysis engine using a specific keyword or phrase included in the document to determine the security level of the copy data.
