Networked medical data sharing on secure medium – A web publishing mode for DICOM viewer with three layer authentication

Abstract

Growing demand for e-healthcare across the globe has raised concerns towards the secure and authentication enhanced medical image sharing. One of the services offered by health informatics in hospitals include an user interface through the Local Area Network (LAN) for enabling storage and access of medical records. In this paper, a security enhanced DICOM image sharing over a LAN addressing confidentiality, integrity and authentication has been proposed. Initially, the AES encrypted patient history was combined along with the thumb impression and Quick Response (QR) code of patient ID as watermark. This watermark was encrypted employing Integer Wavelet Transform (IWT), chaotic map and attractors with confusion-diffusion operations. Further, the encrypted watermark was embedded in the selected Region Of Non-Interest (RONI) pixels of DICOM image. Username & unique password credentials, Face identification and FPGA generated One Time Password (OTP) form the three layer authentication scheme for secure DICOM image access through the LAN. Web publishing medium of storing secured DICOM images in cloud has also been addressed in this work. To validate the proposed hybrid crypto-watermarking system, parameters such as key sensitivity, key space, correlation, entropy, histogram, cropping attack, Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR) and Structural Similarity Index Metric (SSIM) were performed and the results obtained have proved the strength of the proposed algorithm against brute force, statistical and cropping attacks.

Chaos blended cellular automata on fractals: the effective way of reconfigurable hardware assisted medical image privacy

“…Attractors have the capacity to describe physical systems in a deterministic fashion and yet give rise to inherently unpredictable solutions. The Lorenz attractor is most famously attributed to the “Butterfly effect”, owing to butterfly like shape that the attractor generates [ 3 ]. This chaotic attractor is derived from the Lorenz System of ordinary differential equations.…”

A Comprehensive Review on Medical Image Steganography Based on LSB Technique and Potential Challenges

“…Lately, vast concerns are raised about the problem of medical information security due to the rising need for telemedicine services and the known fact that applications of medical frequently handle sensitive patient information. This has become an important and crucial issue as it inevitably involves the transfer of medical information over open networks like the Internet (21)(22)(23). Nowadays, maintaining the privacy of medical information is not only an ethical requirement but also a legal one (18,(24)(25)(26)(27).…”

Enhancing Security of Health Information Using Modular Encryption Standard in Mobile Cloud Computing

“…Overall, current role-based access control schemes are not concerned with the HI industry. Several studies [35,36] were presented for efficient and secure architecture against the searchable health-information.…”
