In the present paper we propose a model for a steganography-based digital contents access control system. It is suited for digital content creators who store their digital works in their computers and want to distribute them over the Internet where they make a complete local access control to their works. We have developed a prototype system for Windows and tested its basic performance. It worked well from a technical point of view. The novel point is that the creators don't need to send their works to the content users. They only send keys to extract the digital works out of the image data that the users have downloaded from the creator's home page. We are convinced that this model will serve as a new content distribution scheme for content creators in the Internet age for today and tomorrow.
