Abstract

A computing device segregates licenses for corresponding content according to relatively short lived licenses for relatively short lived content and relatively long lived licenses for relatively long lived content. The computing device stores the relatively short lived licenses in a more temporary and volatile license store, and the relatively long lived licenses in a more permanent and non-volatile license store. Thus, the relatively short lived licenses are deleted when the temporary license store is turned off and do not create disorder in the permanent license store.
