Secured Medical Data Transfer Using Reverse Data Hiding System Through Steganography

Reversible Data Hiding (RDH) is the process of transferring secret data hidden inside cover media to recipient so can securely retrieve both and media. The RDH approach applied in this study field telemedicine, medical-secret conveyed privately via medical video. Morse code-based encryption technique tends encrypt by compression using Arithmetic coding technique. Discrete Shearlet transform (DST) compresses selected frame from video compressed embedded into logical operations. On a receiver side, reversal carried over original will be retrieved stego after retrieved. Password included on side for authentication purposes. Parameters such as time, ratio, Mean Square Error (MSE) Peak Signal Noise Ratio (PSNR) are calculated at maximum iteration proposed algorithm, highest PSNR value achieved. In terms Structural Similarity Index Measure (SSIM), linear increase 0.91 0.99 evident iterations. comparison with other techniques, algorithm reaches higher SSIM 0.999 number Thus, method provides more security recipient.
