ROI lossless colored medical image watermarking scheme with secure embedding of patient data

Transmission of images via internet and it's authentication is of great importance with the booming techniques in the field of networking and information security. Medical imaging and it's secure transmission have grown up as a necessity. This paper focuses on reversible watermarking of medical images, both grey scale as well as color, preserving its ROI. It also effectively manages patient health record by securely embedding it inside the image before transmission which facilitates better archiving of data with comparatively lesser transmission bandwidth and much lesser chaos. This paper considers noisy and noiseless environments as different cases with different implementation for both. Also tamper detection and recovery of ROI makes this quite a useful technique in the upcoming color imaging era.
