Journal ArticleDOI
Addressing cloud computing security issues
TL;DR: This paper proposes introducing a Trusted Third Party, tasked with assuring specific security characteristics within a cloud environment, and presents a horizontal level of service, available to all implicated entities, that realizes a security mesh, within which essential trust is maintained.
Journal ArticleDOI
Securing e-Government and e-Voting with an open cloud computing architecture
TL;DR: This paper explores increasing participation and sophistication of electronic government services, through implementing a cloud computing architecture, and proposes a high level electronic governance and electronic voting solution, supported by cloud Computing architecture and cryptographic technologies.
Journal ArticleDOI
A cloud based architecture capable of perceiving and predicting multiple vessel behaviour
TL;DR: An Artificial Neural Network capable of predicting a vessels future behaviour (position, speed and course), based on events that occur in a predictable pattern, across large map areas is developed.
Journal ArticleDOI
Real-time vessel behavior prediction
TL;DR: A publicly accessible, web-based system capable of real time learning and accurately predicting any vessels future behavior in low computational time is implemented, which can potentially be used as the predictive foundation for various intelligent systems, including vessel collision prevention, vessel route planning, operation efficiency estimation and even anomaly detection systems.
Journal ArticleDOI
Technical guidelines for enhancing privacy and data protection in modern electronic medical environments
TL;DR: A risk analysis study is performed for a Greek shared care environment for the treatment of patients suffering from beta-thalassemia to provide an assessment of the associated risks, focusing on the description of countermeasures in the form of technical guidelines that can be employed in such medical environments for protecting the privacy of personal and medical information.
