About NeGIS

NeGis workshop aims to collect contributions and stimulate discussions on next generation information systems, where new technologies such as cloud and fog computing are employed and (sensitive) data are heavily used, produced and distributed.

NEGIS - Next Generation Information Systems: Modeling, Monitoring, and Management in Cloud and Fog Computing

The amount of data and services supported by Information Systems (ISs) has increased exponentially during the last few years. To improve their efficiency and reduce costs, modern organizations have been shifting their services, with part of their ISs, to the Cloud. More recent developments have shown an inversion towards decentralization and distribution of applications and services in the huge pool of devices and computing facilities available nearer to the customers. This shift is due to the impact of Internet of Things, which is further increasing the amount of data to be stored and computed. Fog Computing is the last frontier for ISs, where data and services can be moved in the continuum of resources between the cloud and the edge.

In this context, the management of ISs can exploit the diversification of the resources available, but at the same time is getting more and more complex and challenging. ISs management should take into consideration the heterogeneity of the cloud/fog infrastructure. Such complex architecture is posing new challenges in the management of modern applications, especially in reference to security, privacy, and energy efficiency. Security and privacy needs to be considered for the amount of sensitive data possibly produced and the high level of distribution of them, while energy efficiency is central, due to the high amount of computational nodes in today’s ISs. These requirements can significantly change from application to application, and a universal solution is not possible. For these reasons, new solutions are needed for monitoring and modeling applications and services in modern ISs, and for enforcing the satisfaction of conflicting requirements.

In this workshop we aim to collect contributions investigating issues related to the management of cloud and fog computing in modern information systems with a focus, but not limited, on energy efficiency, security, and privacy, their relations and trade-off with other requirements such as response time and throughput. In doing so, we are considering both the application components of the information system with their complexity, as well as the management of the data used by such applications. We also consider the impact of the human in the loop, looking at how the awareness and the behaviors of users and designers in socio-technical systems can affect the effective adoption of energy and security policies.

Shaping the new generation of Data Privacy Management Systems: Lessons learned from DEFeND

ABSTRACT: New technological advances such as Cloud Computing, the Internet of Things, Fog Computing, and Big Data provide benefits and have changed the way we store, access and exchange information. In fact, the rapid development and advances in ICT have led to their adaption by organisations (enabling them to transform their business to digital services, increasing their efficiency), public authorities (enabling them to provide new services to citizens and reduce complexity) and individuals (enabling them to communicate and share personal information faster and more efficient). However, together with all the benefits that such technologies bring, opportunities (deliberate or accidental) for misuse of user data are also created mostly due to lack of control over management and privacy issues of user data.  
This talk outlines the main challenges to data privacy governance looking at its three main levels: information systems, people, and organisations. The talk motivates the main requirements and discuss a model-based data governance approach for the development of a next generation information platform for data governance for privacy. The talk is based on research and results of the EU funded DEFeND project.
