Understanding the impact of privacy concerns and trust on social networking sites: Analysing user intentions towards willingness to share digital identities

Participation in social networking sites (SNS) has dramatically increased in recent years. SNS focus on building online communities of people who share interests and/or activities, or who are interested in exploring the interests and activities of others. This study examines the experiences of SNS users, and explores how the depth of their experience and knowledge of the Internet, trust and privacy concerns impact upon their individual willingness to share information about their own identity with other users on social networking websites. An acceptance model is proposed that incorporates cognitive, as well as affective, attitudes as primary influencing factors on user attitudes and behaviour which, in turn, are driven by underlying beliefs, perceived levels of privacy and trust, attitudinal experiences and knowledge, as well as a willingness to share. The proposed conceptual model for this study is derived from the literature review and Theory of Planned Behaviour. This model explains how people experience different levels of motivation about sharing knowledge and seeking information from other members which, in turn, leads to a divergence in both intentions and behaviours within virtual communities. The model shows excellent measurement properties and establishes two distinct constructs—specifically, the need for perceived levels of privacy, and the need for established levels of trust within SNS. This study is based on quantitative methodology and uses a structural equation model to test the construction of the model and its hypothesis. The data for this study were collected from a Facebook forum, with a sample size of 155 SNS users. The main theoretical contribution of this study is to provide greater understanding and new insights into privacy concerns and trust, in so far as these factors impact upon SNS users‘ willingness to readily share information regarding their digital identities. Secondly, this study will enrich the existing literature regarding the inter-relationship between the extent of SNS users‘ length and depth of experience as Internet users, as this impact upon their willingness to share identity-based information

Modelling the relationship between design activity and computer-supported collaborative design factors

Computer-Supported Collaborative Design (CSCD) technologies can enable teams to collaborate across boundaries. Emerging research documents the potential of CSCD technologies to contribute towards successful collaborative design, however, no model exists to define the relationship between a successful design activity and CSCD factors which influence its success. This paper utilises a systematic literature review to categorise known CSCD factors, categorise and characterise them, and applies this knowledge towards developing an established design activity model to include CSCD factors

IoT Design Challenges and the Social IoT Solution

The IoT (Internet of Things) promises to be the major phenomenon in information technology in the near term. By some forecasts more than half of all new IT system deployments by 2020 will incorporate some form of IoT technology. Currently, however, there is no dominant IoT platform and no universal IoT design standards currently in use. This contributes to Architectural Heterogeneity which in turn contributes to high integration costs and inhibits IoT benefits realisation. The use of universal design standards presents one solution to this problem. Social Internet of Things (SIoT) methods use the way that people manage social relationships as a reference architecture for the way to manage the interaction between the various Things in an IoT network. This paper discusses some of the current IoT design challenges and presents solutions couched in SIoT that can be used as standards for future IoT designs to reduce Architectural Heterogeneity

A machine-machine collaboration formalism based on web services for groupware tailorability

International audienceIn this paper, we propose a machine-machine collaboration formalism to support groupware tailorability. Our work is based on the 3C functional model by Ellis that decomposes collaboration between users into communication, coordination and cooperation phases. Through our research, we realized that Web services are powerful distributed components offering the desired tools in order to adapt a groupware system to the real needs of users. Therefore, we use this technology to define a collaboration protocol between machines over the network for implementing tailorability in CSCW systems. A groupware architecture is presented based on the proposed formalism. We argue that a protocol between machines over the internet should be defined in order to exchange common services in real time collaboration

Enhancing quality of life: Human-centered design of mobile and smartwatch applications for assisted ambient living

Background: Assisted ambient living interfaces are technologies designed to improve the quality of life for people who require assistance with daily activities. They are crucial for individuals to maintain their independence for as long as possible. To this end, these interfaces have to be user-friendly, intuitive, and accessible, even for those who are not techsavvy. Research in recent years indicates that people find it uncomfortable to wear invasive or large intrusive devices to monitor health status, and poor user interface design implies a lack of user engagement. Methods: This paper presents the design and implementation of non-intrusive mobile and smartwatch applications for detecting older adults when executing their routines. The solution uses an intuitive mobile application to set up beacons and incorporates biometric data acquired from the smartwatch to measure bio-signals correlated to the user’s location. User testing and interface evaluation are carried out using the User Experience Questionnaire (UEQ). Results: Six older adults participated in the evaluation of the interfaces. Results show that users found the interaction to be excellent in all the parameters of the UEQ in the evaluation of the mobile interface. For the smartwatch application, results vary from above average to excellent. Conclusions: The applications are intuitive and easy to use, and data obtained from integrating systems is essential to link information and provide feedback to the user.info:eu-repo/semantics/publishedVersio

Resilient Workflows for Cooperative Design

International audienceThis paper describes an approach to extend process modeling for engineering design applications with fault-tolerance and resilience capabilities. It is based on the requirements for application-level error handling, which is a requirement for petascale and exascale scientific computing. This complements the traditional fault-tolerance management features provided by the existing hardware and distributed systems. These are often based on data and operations duplication and migration, and on checkpoint-restart procedures. We show how they can be optimized for high-performance infrastructures. This approach is applied on a prototype tested against industrial testcases for optimization of engineering design artifacts.his electronic document is a "live" template.
