This book introduces medical imaging its security requirements and various security
mechanisms using data hiding approaches. The book in particular provides medical data hiding
techniques using various advanced image transforms and encryption methods. The book focuses on
two types of data hiding techniques: steganography and watermarking for medical images. The
authors show how these techniques are used for security and integrity verification of medical
images and designed for various types of medical images such as grayscale image and color
image. The implementation of techniques are done using discrete cosine transform (DCT)
discrete wavelet transform (DWT) singular value decomposition (SVD) redundant DWT (RDWT)
fast discrete curvelet transform (FDCuT) finite ridgelet transform (FRT) and non-subsampled
contourlet transform (NSCT). The results of these techniques are also demonstrated after
description of each technique. Finally some future research directions are provided for
security of medical images in telemedicine application.
