Abstract
Local storage on player instruments provides the ability for adding further amendments and most recent supplements to the optical disc content. A problem arising with this technically applicable possibility is the protection of copyrights bound to disc and supplement data. The present invention describes a technique to ensure a security framework that is able to handle this, by creating a virtual file system (VFS) by merging optical disc data and local storage data based upon a common identifier.
