Thanks to recent advances in sensors, communication and satellite technology, data storage, processing and networking capabilities, satellite image acquisition and mining are now on the rise.

This book introduces medical imaging, its security requirements, and various security mechanisms using data hiding approaches. 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 performance of the proposed method is evaluated using various transform bases like Discrete Fourier Transform (DFT), Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), Singular Value Decomposition (SVD), and Fast Discrete Curvelet Transform (FDCuT).
