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.
Claims12
A method for a computing device to store digital licenses for rendering corresponding pieces of digital content, the method comprising:
- the computing device segregating the licenses according to relatively short lived licenses for relatively short lived content and relatively long lived licenses for relatively long lived content;
- the computing device storing the relatively short lived licenses in a more temporary and volatile license store;
- and
- the computing device storing the relatively long lived licenses in a more permanent and non-volatile license store,
- whereby 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.
A computer-readable medium having stored thereon computer-executable instructions implementing a method for a computing device to store digital licenses for rendering corresponding pieces of digital content, the method comprising:
- the computing device segregating the licenses according to relatively short lived licenses for relatively short lived content and relatively long lived licenses for relatively long lived content;
- the computing device storing the relatively short lived licenses in a more temporary and volatile license store;
- and
- the computing device storing the relatively long lived licenses in a more permanent and non-volatile license store,
- whereby 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.
