The proliferation of multimedia big data for dissemination and sharing of massive amounts of information raises important security and privacy concerns. One such concern is the composition and enforcement of privacy policies in order to securely manage access of multimedia big data. Several researchers have pointed out that for proper enforcement of privacy policies, the privacy requirements should...
Adopting IT as an integral part of business and operation is certainly making the healthcare industry more efficient and cost-effective. With the widespread digitalization of personal health information, coupled with big data revolution and advanced analytics, security and privacy related to medical data — especially ensuring authorized access thereto — is facing a huge challenge. In this paper, we...
In the last years, the increasingly use of ICT in Healthcare has led to the generation of several healthcare information systems, such as Electronic Health Record systems, which enable the management and sharing of digital clinical data. Since clinical data is generally characterized by very sensitive information, such information systems have to be able to limit their sharing of it, by enabling or...
RFID and WSN technologies are widely used in today's pervasive computing. In Wireless Sensor Networks, sensor nodes sense the physical environment and send the sensed data to the sink by multi-hops. WSN are used in many applications such as military and environment monitoring. In Radio Frequency Identification, a unique ID is assigned to a RFID tag which is associated with a real world object. RFID...
The security and privacy of patient information is one of the biggest hindrances to the wide adoption of eHealth systems. For eHealth systems to be successful they must provide protection for patients' privacy while ensuring healthcare professionals are able to access the information necessary to provide appropriate care. Accountable-eHealth systems are a proposed solution to these potentially competing...
Pervasive applications promote a seamless integration of computer artifacts with our daily an business lives. However, they threaten privacy in two ways. Firstly, adaptation to a user's context necessitates a large collection of data. Secondly, context should be addressed when granting users access to information. This paper handles privacy management as an access control problem and argues that privacy...
The paper first discusses motivations why taking into account location information in authentication and access control is important. The paper then surveys current approaches to location-aware authentication, including the notion of context-based flexible authentication policies, and to location-aware access control, with focus on the GEO-RBAC model. Throughout the discussion, the paper identifies...
This paper describes an approach using the context based dynamic security service for adaptive healthcare applications. In particular, we focus on the security model using the dynamic access control based on context. Adaptive applications in home environment can be achieved via adaptive personal healthcare services that utilize the dynamic service reconfiguration according to the user's context. Evidently,...
In electronic healthcare several research and standardization activities are emerging that promote federation. In this scenario, the medical information present at different healthcare providers, such as hospitals, general practitioners, test laboratories, etc., are shared for an improved quality of experience from the patient perspective. However, sharing of medical data on a large scale exposes...
