DWT-SVD based reversible watermarking algorithm for embedding the secret data in medical images

There are different ways to protect medical images, most commonly used are steganography, watermarking, encryption etc. Due to the advantages of watermarking it has achieved a great importance in the field of image security. This paper gives a comparative analysis on applying SVD on different sub bands of a Haar wavelet transformed medical image. The experimentation is done using MRI and CT scan medical images.
