Abstract

Apparatus consisting of a single executable object, or multiple objects acting together, that contain multimedia or similar content and an associated player that acts to control access to the said content. The single executable object may be provided as a series of smaller blocks, the order of which may have been shuffled, and reconstructed using a key supplied by the content provider. The single executable object may also contain various key series in order to further control access to the content where elements of these keys may also be derived from identifying features provided by the user or the user's hardware or software. Keys thus derived from locally identified features may be incorporated within the single executable object as it is reconstructed thus ensuring that the content may only be viewed or be copied as intended by the content provider.
