N2 - Digital rights management systems seek to control the use of proprietary material (e.g., copyrighted movies). The use of DRM introduces a new set of caching issues not previously studied. Technically, these problems include elements of ski rental algorithms as well as paging, and their generalizations, online "capital investment" and generalized caching (the Landlord algorithm). The introduction of DRM restrictions does not impact the competitive ratio by more than a constant factor.
