Abstract
Disclosed are a clipboard protection system in a DRM environment and a recording medium in which a program for executing the method in a computer is recorded. An identification information management unit changes first identification information of data, which is to be stored in a clipboard, into second identification information when data stored in the clipboard is requested by a reliable object, and outputs the second identification information corresponding to identification information of the reading target data if the reliable object requests extraction of the data stored in the clipboard. A data protection unit encodes the data, which is to be stored in the clipboard, and decodes the encoded data which is read from the clipboard. If the extraction request for the data stored in the clipboard is inputted from the reliable object, a control unit delivers to a clipboard management system the second identification information corresponding to the identification information of the reading target data, and requests the encoded security data to be read and provided from the clipboard. According to the present invention, the access to the security data by a non-reliable object can be blocked.
