摘要：This paper proposes a robust information hiding method by utilizing the spectrum efficient OFDM technique applied on gray scale image onto another gray carrier image. For simplicity, the data mapping in complex domain we have used 4-QAM. A modified QIM technique for data embedding is used for improving robustness. But the robustness analysis is not a common practice for QIM based data hiding. The result shows a large amount of information hiding capability along with substantial improvement in robustness against intentional impairments. But the possibility of using OFDM technique in robust high capacity data hiding has drawn a very little attention to the researchers even today.
