METHOD FOR DATA PREPARATION AND WATERMARK INSERTION

摘要

A method for data preparation and watermark insertion. The method includes the step of preparing the data at a first time by manipulating at least one set of the data characteristics (306) for subsequent insertion of a first watermark (2). In a preferred embodiment of the method of the present invention the method further includes the step of inserting the first watermark by manipulating the set of data characteristics at a second time subsequent to the first time. In a variation of the present invention a method for inserting a watermark into compressed data is provided. The compressed data has sets of data characteristics. The method includes the steps of inserting a watermark by manipulating the set of data characteristics; and optimizing the manipulated data by modifying the compressed data characteristics subject to a set of constraints (308, 310).
