Interpretable Machine Learning for Privacy-Preserving Pervasive Systems

Our everyday interactions with pervasive systems generate traces that capture various aspects of human behavior and enable machine learning algorithms to extract latent information about users. In this paper, we propose a machine learning interpretability framework that enables users to understand how these generated traces violate their privacy

Empowering users to control their privacy in context-aware system through interactive consent

Context-aware systems adapt their behaviour based on the context a user is in. Since context is potentially privacy sensitive information, users should be empowered to control how much of their context they are willing to share, under what conditions and for what purpose. We propose an interactive consent mechanism that allows this. It is interactive in the sense that users are asked for consent when a request for their context information is received. Our interactive consent mechanism complements a more traditional pre-configuration approach. We describe the architecture, the implementation of our interactive consent mechanism and a use case

Context for Ubiquitous Data Management

In response to the advance of ubiquitous computing technologies, we believe that for computer systems to be ubiquitous, they must be context-aware. In this paper, we address the impact of context-awareness on ubiquitous data management. To do this, we overview different characteristics of context in order to develop a clear understanding of context, as well as its implications and requirements for context-aware data management. References to recent research activities and applicable techniques are also provided

A Middleware-based Approach for Context-aware Computing

Ubiquitous computing environments integrate a large number of heterogeneous devices, which convey an increasing level of complexity when developing ubiquitous applications. A solution to this problem resorts to the use of a software abstraction layer, known as middleware, which encapsulates the underlying elements of the environment and offers unified and standardised access to applications which need to make use of the resources of the environment. Moreover, a middleware layer can also provide high-level built-in services, such as context management services.Ministerio de Educación y Ciencia TIN2006-15617-C0
