We present a software-based protection mechanism to prevent unauthorized copying of media documents during their presentation on a clients host. Our solution enforces the execution and continuous replacement of security mechanisms on the clients host. Each protection mechanism is only used for a short time interval before it is replaced. The short duration of the time interval prevents a successful analysis and attack of the mechanism. In this way we solve a shortcoming of current solutions. As those employ fixed protection mechanisms they will eventually be circumvented because attackers have virtually unlimited time to analyze them.
