“…However, the size of the RONI limits the embedding capacity of the watermark [17], and all the information in the RONI can be destroyed by replacing the RONI in space [18]. To solve the problem that embedding watermarks in the ROI affects the doctor's diagnosis, some researchers have made the ROI reversible [19,20], also claiming that the ROI is lossless [21]. e characteristic of this kind of algorithm is that the ROI can be completely restored when extracting the watermark.…”

To protect the patient information in medical images, this article proposes a robust watermarking algorithm for medical images based on Harris-SURF-DCT. First, the corners of the medical image are extracted using the Harris corner detection algorithm, and then, the previously extracted corners are described using the method of describing feature points in the SURF algorithm to generate the feature descriptor matrix. Then, the feature descriptor matrix is processed through the perceptual hash algorithm to obtain the feature vector of the medical image, which is a binary feature vector with a size of 32 bits. Secondly, to enhance the security of the watermark information, the logistic map algorithm is used to encrypt the watermark before embedding the watermark. Finally, with the help of cryptography knowledge, third party, and zero-watermarking technology, the algorithm can embed the watermark without modifying the medical image. When extracting the watermark, the algorithm can extract the watermark from the test image without the original image. In addition, the algorithm has strong robustness to conventional attacks and geometric attacks. Especially under geometric attacks, the algorithm performs better.

The fast improvement of the advanced media innovation and the web permit individuals will copy, transmit, appropriate Furthermore store data more undoubtedly. Restorative pictures traded in open networks oblige a technique with give acceptable secrecy for the image, genuineness of the picture proprietorship Also hotspot from claiming origin, Also picture integument confirmation. This Look into keeps tabs for blind watermarking from claiming Medical images, both ash scale and in addition color, preserving its ROI. It also successfully manages tolerant wellbeing record Eventually Tom's perusing safely embedding it inside those picture in front of transmission. The paper is introduce new Embedding Process with Discrete Wavelet Transform and Singular Value Decomposition then relate with others methods performance with different Rotational attacks to demonstrate with parameters. Also Attack detection and recovery of ROI using pseudo Zernike moment and affine transform made this very functional method in the approaching color picture watermarking areas.
