Multi secure and robustness for medical image based steganography scheme

Medical records are extremely sensitive patient information and require uncompromising security during both storage and transmission. In this paper a multi secure and robustness of medical image based steganography scheme is proposed. The proposed technique provides an efficient and storage security mechanism for the protection of digital medical images. We proposed a viable steganography technique using Integer Wavelet Transform (IWT) to protect the MRI medical image into a single container image. The container image was taken and flip left was applied and the dummy container image was obtained. Then the patient´s medical diagnosis image was taken as secret image and Arnold transform was applied and scrambled secret image was obtained. In the first case, the scrambled secret image was embedded into the dummy container image and Inverse IWT was taken to get a dummy secret image. In the second case, the container image was taken and fused with the dummy secret image and stego image was obtained. The quality of the recovered medical image showed acceptable visual quality. It is observed that the quality parameters are improved with acceptable PSNR compared to the existing algorithms.
