Abstract: Methods for preventing ad stripping from ad-supported digital content include removing part of the content, and using a digital rights management (DRM) proxy server to provide links to any removed content part and to ads to be inserted in the content to a player who plays the content with the ads. The DRM proxy server ensures that the player cannot distinguish between removed content parts and the ads. A system enabling the method includes in addition to the DRM server and player an encoder used to remove at least one part from the content, encode the remaining content and the removed part and supplying links to each removed part to the DRM proxy server. The system further includes an ad server used to provide links to ads to the DRM proxy server.
