Kostiantyn V. Zashcholkin, Олена Іванова · 2015
The paper proposes the technology of control of integrity and legitimacy of information object usage with the Look Up Table-oriented (LUT- oriented) architecture. The technology is based on embedding the self-recovery digital watermark into information objects of such kind. The technology is the composition of approaches to forming the self-recovery digital watermarks in the passive multimedia containers, and approaches to embedding the extra information into LUT-containers. The process of embedding the extra information occurs with the help of classification of container elements and their purposeful modification within the set of the formed classes. The procedure of immediate embedding the data at the level of LUT-container elementary parts includes the value inversion of current processed LUT unit and propagation of the inversion around all the inputs of LUT units connected to the current unit output. The description of practical realization of the proposed technology is represented.
