Abstract: A method for controlling the release of an as-rendered configuration of a digital work, comprising the steps of presenting said digital work as a composite of a plurality of layers comprising at least a first layer and a second layer; providing a rendering protocol interface which is adapted for defining said as-rendered configuration of the digital work by specifying a first rendering status of said first layer and a second rendering status of said second layer; providing a rendering protocol facility adapted for storing and controlling the release of said first and second rendering status of said first and second layers respectively in accordance with said as-rendered configuration; restricting unauthorized access to the rendering protocol interface, thereby preventing unauthorized modification of said as-rendered configuration; and releasing said digital work with said as-rendered configuration. The method has application in selling books, movies, software, music and other information products.

Abstract: A method for controlling distribution and access to an information product, said method comprising the steps of: superposing a utility-reducing masking effect on said information product; controlling the presence, absence and/or permanence of said masking effects by the outcome of an interactive communication between a provider and a receiver of said information product. The term information product includes books, video recordings, audio recordings, music, images and multimedia works. The masking effects described in the present invention are of a generally interfering nature and can be superposed on the information object as an overlay, interruption, interference, discontinuity, disturbance or disorientation. The purpose of imposing a masking effect is to derive a masked version of the information product for preview purposes that can be readily distributed to interested customers in an unrestricted manner.
