Study on Medical Image Watermarking Techniques

S. Priya, B. Santhi and P. Swaminathan

Security of medical image is possible by using digital watermarking techniques. The significant information is embedded within a host medical image in order to provide integrity, consistency and authentication in healthcare information system. Authentication is done by embedding significant information in spatial as well as in transformed domains. This study proposes a reversible invisible watermarking technique to embed significant information within a Computed Tomography host medical image by using different transformed domains. Watermarked image is evaluated by verifying peak signal to noise ratio (PSNR) value and Structural Similarity Index Measures (SSIM). In the analysis, wavelet transform based watermarking technique PSNR value is high and SSIM value is nearly equal to 1 states that for medical image wavelet transform gives best reversible watermarking compare with other watermarking techniques.
