AB  - Medical images are transmitted to another remote place in telemedicine. Medical images need to be protected against any modification which made by the attacker through the unsecured channel. Watermark can be used to check the integrity of a medical image before diagnosis. In this study, a new fragile watermarking technique has been suggested for medical image authentication, tampering localization. In the suggested scheme, two watermarks have been used. The first one is used for checking whether the medical image has tampered or not. The second one is used for localizing the tampered region within a medical image. These watermarks are embedded in the frequency domain of the medical image. Experimental results showed that the suggested scheme can decide whether the medical image is tampered or not, accurately. In addition, the tampered region is localized perfectly.
