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.]]>Amirtharajan, R. and J.B.B. Rayappan,2012193115124Amirtharajan, R. and J.B.B. Rayappan,201212428439Amirtharajan, R. and J.B.B.
