<p>Provided is an information processing device capable of restricting the use of applications or sets of content on unauthorized devices on to which applications or sets of content have been copied. An install-status-information install unit (32) installs install-status information of applications or sets of content installed on a storage unit (30), i.e. information that expresses the install status of an application or a set of content during a specified reference time, on the storage unit (30) as a constituent element of the application or set of content. When use of an application or set of content is initiated, a usage restricting unit (34) restricts the usage of the application or set of content if the current install status of the application or set of content differs from the install status indicated by the install-status information.</p> |
