A method of preparing a digital medical image for secure transmission, the method comprising embedding data into the digital medical image using a reversible watermarking process, generating a code for tamper detection and localization from the digital medical image using a computational function, and embedding the code for tamper detection and localization into the digital medical image using the reversible watermarking process; and a method of reviewing a digital medical image prepared by the method of preparing, the method of reviewing comprising retrieving the code for tamper detection and localization from the digital medical image; reversing the watermarking processes to obtain a restored image; generating a code from the restored image using the computational function; and comparing the retrieved code for tamper detection and localization with the code generated from the restored image to detect and locate tampering. |
