<p>A method of distributing an original media file by downloading at a client a corrupted media file. The media is corrupted by omitting some data from the original media file, storing the corrupted media file and the data left out separately. The excluded data may be selected to maximise corruption. The method then involves after entering into a financial transaction connecting to a server and receiving the omitted data which is used to recreate the original media file. The recreated media file may be the subject of DRM. Instead of corrupting the original media file a dummy media file may be used for download or the media may be downloaded in a different format with different aspect ratio or sound quality. The object is to entice the illegal downloader to purchase a legitimate copy of the media by leveraging the time take to acquire a illegal copy. Promotional material may be inserted into the original media before download.</p> |
