Abstract
A digital work and a system context (or resource information or system resource) are polarized enabling trusted rendering or replay of the digital work without depolarization of the digital content. The digital work includes digital content and resource information. Resource information may include information used by a replay application to format or process the digital content. The digital work and system context are polarized using a polarization scheme which relies on a polarization seed to initialize and customize the polarization. Different types of polarization seeds may be used, including a random number, a user's system's state or characteristic and a dynamic state-based polarization seed based on a dynamic system state or characteristic.
