Reversible and imperceptible watermarking is recognized as a robust approach to confirm the integrity and authenticity of medical images and to verify that alterations can be detected and tracked back. In this paper, a novel blind reversible watermarking approach is presented to detect intentional and unintentional changes within brain Magnetic Resonance (MR) images. The scheme segments images into two parts; the Region of Interest (ROI) and the Region of Non Interest (RONI). Watermark data is encoded into the ROI using reversible watermarking based on the Difference Expansion (DE) technique. Experimental results show that the proposed method, whilst fully reversible, can also realize a watermarked image with low degradation for reasonable and controllable embedding capacity. This is fulfilled by concealing the data into 'smooth' regions inside the ROI and through the elimination of the large location map required for extracting the watermark and retrieving the original image. Our scheme delivers highly imperceptible watermarked images, at 92.18-99.94 dB Peak Signal to Noise Ratio (PSNR) evaluated through implementing a clinical trial based on relative Visual Grading Analysis (relative VGA). This trial defines the level of modification that can be applied to medical images without perceptual distortion. This compares favorably to outcomes reported under current state-of-art techniques. Integrity and authenticity of medical images are also ensured through detecting subsequent changes enacted on the watermarked images. This enhanced security measure, therefore, enables the detection of image manipulations, by an imperceptible approach, that may establish increased trust in the digital medical workflow.

“…Further, 2D prediction error histogram has been explored in [18]. Apart from this, an entirely different technique also has been used for reversible data hiding in [8], [19]- [23]. Reversible data hiding scheme for encrypted images include reversible data hiding by Reserving Room before Encryption (RRBE), and reversible data hiding by Reserving Room after Encryption (RRAE).…”

Image encryption and reversible data hiding are two major areas of research in the field of information security. In this paper, we propose a new reversible data hiding scheme that provides an encrypted image as output, and which will be useful in secure medical image transmission. The novelty of the proposed scheme is that it generates an encrypted image as a by-product of reversible data hiding process. In the proposed scheme, the consecutive higher bit-planes having compression ratio less than 1 while using run-length coding with Elias-Gamma encoding scheme is considered. The compressed bits will be pseudorandomly distributed in the same bit-plane, and the space created as a result of compression has been used to hide the secret message bits. Finally, the modified bit-planes are combined to generate the encrypted image. Experimental study shows that the proposed scheme outperforms the existing schemes in terms of embedding rate without compromising encryption efficiency.

“…Additionally, in patent and copy shield of multimedia data, the privacy and security are of ultimate significance. For instance, for medical images, the images and Electronic Patient Record (EPR) is transmitted to interested destinations through insecure channels of Internet [5]- [13]. A small variation of these medicinal images can leads to improper analysis and thus results in a deadly health difficulty.…”

In this paper, a novel chaotic encryption-based blind digital video watermarking technique (DVWT) is presented for grayscale and color images. This method makes use of Discrete Cosine transform (DCT) prior to embed the watermark in the hosting video. The hosting video is split into frames of 8*8 nonoverlapping blocks before employing DCT, and watermark bit is implanted by altering the variations among the nearby DCT coefficients of neighboring blocks. Arnold transform is applied for chaotic encryption to offer extra security to the watermark. A set of three versions of the proposed model has been applied and the results are investigated. The experimental outcome confirms that the DCT-VWT is efficient on different image processing functions such as JPEG compression, sharpening, cropping, and median filtering. The comparative analysis ensures that the presented DCT for digital video watermarking technique (DCT-DVWT) is efficient under subjective as well as objective way.
