Secure, Based on Pixel Value Encoding-Decoding Method for Medical Color Image Cryptography

Protecting the medical colored digital image from intruders or from the process of penetration is very important, because the medical digital image may be secret or private, or it may be a carrier of confidential data. In this research paper, we will present a new method for encrypting and decrypting the medical digital image in order to secure the protection process for the medical digital image. The introduced method will use image-private key to apply image cryptography, this key will be kept in secrete and it can be used to encrypt-decrypt any image with any size, The image key can be easily changed when the needs arise to insure the security issues. The proposed method will tested to show that it will provide excellent values for MSE and PSNR to prove that the method will satisfy the requirement of good method of medical image cryptography.
