ABSTRACT:
An object of the present invention is to provide a system which reliably protects a copyright of contents in a deciphered version without unreasonably restricting the execution of the copyright. To this end, according to the present invention, there is provided a system including a storage medium, application executing means for activating an application, access monitoring means for monitoring the status of access of the application to the contents by associating inherent information for the application brought into an activated status by the application executing means with inherent information for the contents accessed by the application, and filtering means for enciphering the contents with the inherent information for the application when the application writes the contents into the storage medium while deciphering the contents with the inherent information for the application when the application reads out the contents from the storage medium.
