ViMDH: Visible-imperceptible medical data hiding for Internet of Medical Things

This paper presents a visible and imperceptible medical data hiding technique, namely ViMDH, that can prevent to intellectual property theft of medical records. The carrier image is visibly marked with logo mark, which is suitable for owner identification and avoid illegal duplication, and then a imperceptible data hiding based on non-subsampled shearlet transform (NSST), redundant discrete wavelet transform (RDWT) and multiresolution singular value decomposition (MSVD) is introduced. Finally, key-based encryption scheme designed by RDWT-RSVD ensure the security of the watermarking system. Under the experimental evaluation, our ViMDH is not only visible and imperceptible, but also has a satisfactory advantage in robustness and security compared with the traditional watermarking schemes.
