本文提出了一种应用于远程诊疗医学图像水印算法，将病人的个人信息制成水印，按一定的嵌入规则嵌入到经过DCT变换后的医学图像中，在提取水印时不需要原始图像。仿真实验表明该水印算法的不可见性好，原始图像失真烧，对噪声、JPEG压缩处理等常规图像操作时的鲁棒性较高，有效地保护了病人的个人信息，防止了个人隐私的泄露。

This paper proposes a treatment applied to the remote medical image watermarking, the watermark is made from the patient's personal information, according to certain rules embedded in the medical image has been embedded into DCT transformed, and does not require the original image when extracting watermark. Simulation results show that the algor-ithm is invisible watermark is good, the original image distortion burn, noise, JPEG compression robustness of conven-tional image processing operation is high, the effective protection of the patient's personal information, to prevent disclo-sure of personal privacy.
