The continuously and rapidly changing landscape in the fields of communications, Internet and social media make it imperative for professionals to better understand the role of Information and Communication Technologies and their impact on everyday activities. Several frameworks have been proposed in order to capture various dimensions of social media and measure their impact on people's social, professional and other activities. The effect of social media and Web 2.0 applications on the healthcare sector is also significant. This paper examines Greek healthcare professionals' attitudes towards internet, social media and mobile technologies, explores their familiarity with social networks and associates their answers with their professional profile. The results of this exploratory study are discussed within the context of the growing international relevant literature.
The main purpose of a virtual healthcare community is to enforce members' collaboration and allow them collectively conduct health care activities. Patient monitoring and medical consultation and support are the most popular activities inside health care communities. They bring together medical experts and patients and require confidentiality, reliability and trust in order to be successful. An examination of existing virtual communities for healthcare leads to the conclusion that many of them fail to meet requirements for building trust. Several ethical, legal and technical issues must be considered in order to build a trustful community. This work presents the architecture of a virtual healthcare community portal with emphasis on the issues that help building trust inside the community. With a set of hypothetical usage scenarios that challenge trust in the community we uncover healthcare community's pitfalls and illustrate the solutions provided by the proposed architecture.

Considering that a triage related task may essentially make-or-break a digital investigation and the fact that a number of triage tools are freely available online but there is currently no mature framework for practically testing and evaluating them, in this paper we put three open source triage tools to the test. In an attempt to identify common issues, strengths and limitations we evaluate them both in terms of efficiency and compliance to published forensic principles. Our results show that due to the increased complexity and wide variety of system configurations, the triage tools should be made more adaptable, either dynamically or manually (depending on the case and context) instead of maintaining a monolithic functionality.
Smartphones have become a vital part of our business and everyday life, as they constitute the primary communication vector. Android dominates the smartphone market (86.2%) and has become pervasive, running in 'smart' devices such as tablets, TV, watches, etc. Nowadays, instant messaging applications have become popular amongst smartphone users and since 2016 are the main way of messaging communication. Consequently, their inclusion in any forensics analysis is necessary as they constitute a source of valuable data, which might be used as (admissible) evidence. Often, their examination involves the extraction and analysis of the applications' databases that reside in the device's internal or external memory. The downfall of this method is the fact that databases can be tampered or erased, therefore the evidence might be accidentally or maliciously modified. In this paper, a methodology for retrieving instant messaging data from the volatile memory of Android smartphones is proposed, instead of the traditional database retrieval. The methodology is demonstrated with the use of a case study of four experiments, which provide insights regarding the behavior of such data in memory. Our experimental results show that a large amount of data can be retrieved from the memory, even if the device's battery is removed for a short time. In addition, the retrieved data are not only recent messages, but also messages sent a few months before data acquisition.
Virtual healthcare communities aim to bring together healthcare professionals and patients, improve the quality of healthcare services and assist healthcare professionals and researchers in their everyday activities. In a secure and reliable environment, patients share their medical data with doctors, expect confidentiality and demand reliable medical consultation. Apart from a concrete policy framework, several ethical, legal and technical issues must be considered in order to build a trustful community. This research emphasises on security issues, which can arise inside a virtual healthcare community and relate to the communication and storage of data. It capitalises on a standardised risk management methodology and a prototype architecture for healthcare community portals and justifies a security model that allows the identification, estimation and evaluation of potential security risks for the community. A hypothetical virtual healthcare community is employed in order to portray security risks and the solutions that the security model provides.
