Abstract: A method, system and computer readable medium for the blocking of recording digital content at an end user multimedia end-user-system during the rendering of encrypted digital multimedia files. Before the process of rendering of encrypted digital multimedia can be started all rendered media stream during playback are opened to ensure that this multimedia content is not recorded. This blocks the usage of the devices and/or ports that can be used to store un-encrypted content that has been decrypted for the purposes of playing or rendering. The method also includes an exception, which allows recording with permission from the present invention.
