Abstract

Abstract

To make the generalized interger transform used for lossless information hiding more generalized and improve the data embedded capacity, a new lossless information hiding method based on expanded generalized integer transform is proposed for image. By introducing the variable parameterm and expanding the generalized integer transform, m(n-1) bit data can be embedded into one image block withn pixels, improving the embedded capacity whenm＞1. Besides, 5 the method uses a new data embedding strategy to improve the quality of the hidded image. Compared with current integer transform algorithms, there is a certain improvement in the embedded capacity and the quality of hidded image with the proposed algorithm. The proposed method can be used to some important and sensitive areas, i.e. military comunication, healthcare, and law-enforcement, after extracted the embedded secret data, the cover image can be recovered losslessly.
