Abstract
A method and system for network-based distribution of content are disclosed. The distribution of content is not only secure but also controlled. The security restricts access to content within media files during downloads as well as while stored at a server or client. In one embodiment, each media file is encrypted with a different, randomly generated key. The control over the distribution of the media file can serve to limit the subsequent distribution of media files from clients to other clients. In another embodiment, the control can permit media files to be shared on a limited number of different clients affiliated with the same user. The clients can vary with application but generally are computing devices that have memory storage. Often, the clients are personal computers or other computing devices that are capable of storing and presenting content to their users.
