Privacy is recognized as a fundamental issue for the provision of context-aware services. In this paper we present work in progress regarding the definition of a comprehensive framework for supporting context-aware services while protecting users’ privacy. Our proposal is based on a combination of mechanisms for enforcing context-aware privacy policies and k -anonymity. Moreover, our proposed t...

Locationand context-aware services are emerging technologies in mobile and desktop environments, however, most of them are difficult to use and do not seem to be beneficial enough. Our research focuses on designing and creating a service-oriented framework that helps locationand context-aware, client-service type application development and use. Location information is combined with other conte...

Developing pervasive context-aware systems to construct smart space applications has attracted much attention from researchers in recent decades. Although many different kinds of context-aware computing paradigms were built of late years, it is still a challenge for researchers to extend an existing system to different application domains and interoperate with other service systems due to heter...

In this paper we present the rationale and the main components of a modular and extensible architecture for building and deploying mobile hypermedia software. Using some simple archetypical examples we show how to provide context-aware assistance to the mobile user, as he explores the physical world. We also show that this kind of software systems poses strong requirements on supporting softwar...

Since smart phones with diverse functionalities become the general trend, many context-aware services have been studied and launched. The services exploit a variety of contextual information in the mobile environment. Even though it has attempted to infer activities using a mobile device, it is difficult to infer human activities from uncertain, incomplete and insufficient mobile contextual inf...

This deliverable reviews the state of the art of research related to the support of attention in systems for collaboration and learning. It presents the most relevant results in attention-related research in cognitive psychology. It introduces systems that have been designed with the explicit aim of supporting some attentional processes. It provides an overview of the specific issues related to...

This paper concerns personal privacy and privacy protection in context-aware ubiquitous computing environments. It proposes a privacy ontology solution to facilitate automated processes in privacy control. The development of the privacy ontology is an integrated part of our ongoing effort towards a privacy-respecting middleware solution for context-aware systems.

Based on an ethnographic study of community road signs, we argue that mobile location aware systems fit somewhat with an abundant practice where private persons make and post signs along the roads. People who live along roads have various reasons, and investigate in various ways, to communicate with passing drivers. Even though these road signs are mostly used for interaction outside of the nei...

When interacting with applications, users are less restrictive in disclosing their personal data than if asked in an application-independent context. On a more general level this behavior is termed as privacy paradox. The creation of privacy awareness can assist users in dealing with contextaware services without harming their privacy unintentionally, thereby addressing the privacy paradox. The...

This chapter introduces intelligent technologies applied in electronic healthcare systems and services. It presents an overview of healthcare technologies that enable the advanced patient data acquisition and management of medical information in electronic health records. The chapter presents the most important patient data classification methods, while special focus is placed on new concepts i...
