This paper introduces current watermarking techniques available from the literatures. Requirements for medical watermarking will be discussed. We then propose a watermarking scheme that can recover the original image from the watermarked one. The purpose is to verify the integrity and authenticity of DICOM images. We used ultrasound (US) images in our(More)
This paper opens a discussion about securing telemedicine by looking at attacks to the security by viewing the function of the computer system as provision of information. Categories of attacks are discussed and an overview of watermarking is introduced as one of the security tool, using the medical image as the channel for watermarking. The main objectives(More)
Brunel University currently has four distance learning MSc courses, with over 500 students registered, and one undergraduate distance learning course. Some have been running for over five years, and well-established practices have been developed and provide a basis of support for the university. Quality assurance in the university has always been considered(More)
AbstrAct This paper discusses the use of three published models, the Technology acceptance model (TAM), Rogers diffusion of Innovation theory (IDT), and the Triandis theory of interpersonal behaviour (TIB), and attempts to bring them together in an integrated model to better predict the adoption of new information and communication technologies by a cohort(More)
BACKGROUND Introduction of telehealth into the healthcare setting has been recognised as a service that might be experienced as disruptive. This paper explores how this disruption is experienced. METHODS In a longitudinal qualitative study, we conducted focus group discussions prior to and semi structured interviews post introduction of a telehealth(More)
Having timestamps that are robust and reliable is essential for remote patient monitoring in order for patient data to have context and to be correlated with other data. However, unlike hospital systems for which guidelines on timestamps are currently provided by HL7 and IHE, remote patient monitoring platforms are: operated in environments where it can be(More)
The UK's National Health Service (NHS) is undergoing great reform. Driven by a demand for higher quality health care provision, information and communication technologies (ICT) are increasingly being used as tools to realize this change. We have investigated the use of remote patient monitoring (RPM), using wireless and broadband networks, in three(More)
We describe our experiences of using remote patient monitoring to support the long term management and clinical intervention in patients with chronic disease. Within the project we developed new algorithms to determine from vital signs collected on a daily basis, those patients requiring clinical investigation for their condition. Our aim was for patients(More)
