Medical Image Watermarking using 2D-DWT with Enhanced security and capacity
This work addresses security and authentication issues for medical images in telemedicine, but it appears incremental as it builds on existing 2D-DWT methods with added encryption and compression.
The researchers tackled the problem of securing medical images in telemedicine by proposing a new watermarking scheme based on 2D-DWT, which improved robustness and authentication, and enhanced security and capacity using encryption and compression, as evaluated on a dataset of 194 CTI and 68 MRI cases.
Teleradiology enables medical images to be transferred over the computer networks for many purposes including clinical interpretation, diagnosis, archive, etc. In telemedicine, medical images can be manipulated while transferring. In addition, medical information security requirements are specified by the legislative rules, and concerned entities must adhere to them. In this research, we propose a new scheme based on 2-dimensional Discrete Wavelet Transform (2D DWT) to improve the robustness and authentication of medical images. In addition, the current research improves security and capacity of watermarking using encryption and compression in medical images. The evaluation is performed on the personal dataset, which contains 194 CTI and 68 MRI cases.
