Analyzing robustness of watermarking in medical images based on singular value decomposition in frequency domain using chaotic maps

Abstract

Information security is an important aspect that needs to be addressed while transmitting information across healthcare industry Medical information that is relevant for patient s diagnosis has to be reliable and efficient with good quality control Information needs to be transmitted safely between clinicians without breaching confidentiality as well as preserving original data Protected and secure medical information is essential for health newlineinsurance and better patient management Due to the technological advancement in communication access to any information pertaining to medical images is simple However this convenience also causes substantial increase in illegal operations to medical images such as duplication modification forgery copy right protection and others Therefore the protection of digital media has become an imperative issue Therefore digital watermarking has drawn much attention of research community to resolve these pressing problems due to its advantages The advantages include content protection for audio and video communication of ownership and copyrights document and image security etc newline
