A data hiding system and method for providing a method of embedding multiple layers of hidden data into multimedia data. First, a media unit of the multimedia data is evaluated to determine an appropriate embedding procedure. Next during a first embedding pass, a ruling layer of primary hidden data is embedded into the media unit. In another embedding pass, a governing layer of secondary hidden data is embedded on top of the ruling layer. The secondary hidden data provides control information for controlling the primary hidden data and the host data. Control information such as error correction data, synchronization data, decoding data, and authentication data is embedded in the governing layer. Embedding schemes such as base domain and spectrum domain embedding are employed.

1. A method of embedding hidden data into host data having a media unit, comprising the steps of:evaluating the media unit of the host data; assessing the data hiding capacity of said media unit and selecting at least one embedding space and at least one embedding algorithm to accommodate multiple data hiding goals associated with two different hidden data layers; embedding a ruling layer of primary hidden data into the media unit; and embedding at least one governing layer of secondary hidden data on top of the ruling layer of primary hidden data, such that embedding the primary and secondary hidden data into the host data generates embedded data, wherein the governing layer of secondary hidden data provides control information for controlling the primary hidden data and the host data.
