Preserving Confidentiality and Integrity of DICOM Images Using Cryptographic Algorithms

Digital watermarking scheme is used to hide information in digital documents, images and multimedia files such as video or audio. It embeds a bit-pattern and influences the digital data by modifying its content. Telemedicine is an area where medicine and I&T (information and telecommunications) technology meets and its having the greatest impact on health care delivery. This paper proposed a watermarking scheme based on different security techniques to preserve basic security features such as confidentiality and integrity of DICOM images. The performance of proposed technique has been tested on different criterion and results prove that proposed technique fulfill all the security criterions.
