TLDR
This paper attempts to substantiate the claimed features of multi-transform domain security model based on Arnold transform aimed at spatial de-correlation of the cover image followed by Discrete Wavelet Transform domain based watermark insertion to achieve enhanced robustness while preserving the quality of the image.Abstract:
Telemedicine is a combination of medical information system and information technology, that includes the use of computers for receiving, storing and transmitting medical information over the internet. The potential challenges involved in this communication model include confidentiality, robustness against attacks and integrity. In this article, multi-transform domain security model is proposed based on Arnold transform aimed at spatial de-correlation of the cover image followed by Discrete Wavelet Transform domain based watermark insertion. The salient feature of this combination of transforms is to achieve enhanced robustness while preserving the quality of the image. This paper attempts to substantiate the claimed features by conducting the experiments on the benchmark images (MRI & US-Scan). The results of experiments have been demonstrated through Structural Similarity Index (SSIM), Normal Cross Correlation (NCC) and Peak Signal-to-Noise Ratio (PSNR) quality measures.read more

Toward secure public-key blockwise fragile authentication watermarking
TL;DR: The authors attempt to maximise the change localisation resolution using only one dependency per block with a scheme they call hash block chaining version 1 (HBC1), and show that HBC1, as well as any neighbour content-dependent scheme, are susceptible to another forgery technique that they have named a transplantation attack.
