Summary:This paper presents a reversible invisible watermarking algorithm for the ownership protection and content authentication of medical images. When embedding information in medical images, extreme care is required, to protect the quality of the image to avoid the wrong diagnosis. In the proposed algorithm the patient's unique identity is used for ownership protection and the SHA-256 hash key information is used for content authentication of medical images. The original medical image can be restored after extracting the ownership and authentication watermark information. The new algorithm was successfully tested on a variety of X-ray and MRI medical images and the distortion which is caused by watermarking was assessed by using peak signal to noise ratio, similarity structure index measure and wavelet signal to noise ratio.
