Abstract
A content protection scheme for controlling access to digital content comprises dividing content into data sectors, storing the data sectors on a storage medium and storing selected original data sectors at a remote location. Additional content is unlocked by the remote location only if data from a storage medium correlates to at least a portion of data of the corresponding selected original data sectors.
