System and method for protection of digital works

A method of creating a polarized digital work, wherein the digital work includes digital content and resource information for use by an application that transforms digital content into presentation data, comprising:

• generating a polarization seed for use in a polarization scheme;
• generating a system resource by copying a portion of the digital work's resource information, wherein the system resource includes resource information specific to the digital work for use by the application;
• polarizing the digital work in accordance with a first polarization scheme which polarizes the digital content while preserving the resource information, using the polarization seed;
• and
• polarizing the system resource in accordance with a second polarization scheme using the polarization seed,
• wherein the application uses the polarized system resource to transform the polarized digital work into clear presentation data without depolarizing the digital content, and
• wherein the digital work comprises a digital video work comprising a video steam and resource information comprising sample rate, sample type and sample form.
