“…10 Although sFTP utilizes secure-shell encryption (SSH), there have been more recent developments in data encryption methods for images, and these deserve further investigation. 11 At the start of the project, both sites were in daily communication by email and telephone to clarify initial queries. Subsequently communication was usually limited to requests for reports on emergency cases.…”

Teleradiology can be used to provide health care to rural populations, especially where there is a scarcity of resources, including on-site radiologists. We have established a network link between a commercial teleradiology provider in Bangalore, south India and the Ramakrishna Mission Hospital (RKMH), located over 3000 km away in the north east of India. Image files were transferred to Bangalore via an ADSL connection using secure file transfer protocol. In the 12-month period beginning in August 2007, a total of 962 studies was sent to Bangalore from the RKMH. The average turnaround time for the report to reach the hospital once the images had been received in Bangalore was six hours for non-emergency cases. For emergency cases the turnaround time was consistently below 30 minutes. Because the RKMH was a charitable institution providing rural patients with free or low-cost treatment, no charge was made for the reporting. Our experience demonstrates that remote implementation of teleradiology is possible in rural India. The service has proved valuable for the remote hospital concerned.

“…One is the image integrity and the other is image authenticity. The image integrity verification consists in the detection (and even prevention or correction) of image degradation or alteration, while the authenticity verification allows for determination of authorship of medical images [ 4 ]. Various strategies have been applied to verify the integrity and authenticity of images.…”

A new blind integrity verification method for medical image is proposed in this paper. It is based on a new kind of image features, known as Krawtchouk moments, which we use to distinguish the original images from the modified ones. Basically, with our scheme, image integrity verification is accomplished by classifying images into the original and modified categories. Experiments conducted on medical images issued from different modalities verified the validity of the proposed method and demonstrated that it can be used to detect and discriminate image modifications of different types with high accuracy. We also compared the performance of our scheme with a state-of-the-art solution suggested for medical images—solution that is based on histogram statistical properties of reorganized block-based Tchebichef moments. Conducted tests proved the better behavior of our image feature set.

“…However, according to [4], these measures are not capable of providing the required security for Radiology Information Systems. Information hiding in digital files therefore present interesting possibilities and techniques that can be exploited in improving security in web based teleradiology [5], [6].…”

Improving Access to Radiology Health Care Services in Rural Areas of Developing Nations through a Secure Web Based Teleradiology Steganographic Method

Access to specialized health care services in rural areas of developing nations and in particular sub Saharan Africa countries like Kenya is severely limited due to shortage of experts available in the medical field particularly in special domains of practice like radiology which involves professional examination of medical images e.g. X-rays and Scans (CAT, MRI etc.) for clinical interpretation and diagnosis. These experts albeit in their minimal number are only found within metropolitan areas where wellequipped referral hospitals are located. Consequently, patients from rural areas who survive on meager incomes are forced to make high sacrifices in visiting distant referral hospitals in order to access radiology and other specialized medical services. While it is possible to make a patient's medical images available to a practicing radiologist online e.g. through open network systems inter connectivity and email attachments, these methods don't guarantee the security, confidentiality and tamper free reliability required for a medical information system infrastructure. The possibility of securely and covertly transmitting such medical images to a remote radiologist for clinical interpretation and diagnosis through an enhanced Least Significant Bit (LSB) digital image steganographic technique was the focus of this study. The proposed method was tested in an experimental research that involved a comparison in the carrier file's statistical properties from this technique and the traditional LSB steganographic technique of information hiding. The study revealed improvements in imperceptibility levels in the carrier files used in this technique besides ensuring that the original MI fidelity is preserved one hundred percent by embedding it in a primary random image signal carrier file. The technique recorded a Peak Signal to Noise Ratio(PSNR) of well above 50 decibels for each image used which is well above the 30 decibels recommended for a fairly imperceptible carrier file.
