Abstract Watermarking is effective technology for processing for secure image through transform domain. With ever increases in security threats demands for security in medical images. This paper proposed a Undecimated Discrete Wavelet Transform (SVDUWT) for evaluation of watermarking in medical images. The proposed model is incorporated in two stages. At first, SVD – DWT is performance of embedding of the watermarking in an medical images. Secondly, entrophy scheme is incorporated for computation of pixels in an images, With normal embedding watermarking scheme involved in transformation of low-frequency sub-band of images. The proposed low-frequency bands are classified in to non-overlapping blocks. The experimental evaluation expressed that proposed scheme significant performance in performance analysis of watermarked method. Also, performance of proposed method is evaluated for attack scenario such as noise and scaling attack. The analysis confirmed that proposed model exhibits good performance for medical image watermarking.
