Information Hiding Based On Correlation Analysis And Multimodal Biometrics Study

Recently, with the development and popularity of the Internet, digital signal processing technology and multimedia information security become increasingly important. Information hiding technology as an important branch of information security has attracted many scholars and relevant departments'eyes.This paper briefly describes the history of information hiding technology research, basic principles, theoretical models and classical algorithms and so on. Introduction of information hiding technology in real life with the combination of biometric technology applications.This paper proposes a novel multimodal biometric images hiding approach based on correlation analysis, Compared with existing methods, we representing the biometric images using the corresponding content of cover image results to the generation of the residual images with much less energy. Hiding the residual images instead of the original secret images into the cover image. Embedded in definite,The original Spatial domain algorithm has been improved. Extensive experimental results demonstrate that the proposed approach not only provides good imperceptibility, but also resists some common attacks and assures the effectiveness of network-based multimodal biometrics identification.
