Title: Qualitative Studies in Mobile Privacy

Abstract: Mobile and ubiquitous computing is providing increased opportunities for personal data collection, analysis and exchange. These opportunities promise benefits for individuals and organisations in the areas of health, business, leisure and social interaction. However, with these opportunities come risks to data privacy in ways that individuals find hard to understand or quantify. This also poses challenges to software engineers, who need to develop software systems that are privacy aware, in the absence of clearly articulated privacy requirements that, in any case, are context dependent and may change dynamically during use. In this talk, we will report on our 'adaptive privacy' research programme, focusing in particular on the qualitative research studies that we have conducted over a number of years to better understand the privacy requirements of new pervasive computing technologies. We will also discuss the implications of such studies on the engineering of privacy aware adaptive software systems,

Short Bio. Bashar Nuseibeh is Professor of Computing at The Open University (Director of Research 2001-2008) and a Professor of Software Engineering at Lero - The Irish Software Research Centre (Chief Scientist 2009-2012). Previously he was a Reader in Computing at at Imperial College London and Head of its Software Engineering Laboratory. He is a Visiting Professor at Imperial College London and the National Institute of Informatics (NII), Tokyo, Japan. His current research interests lie at the intersection of of requirements engineering, adaptive systems, and security and privacy. He served as Editor-in-Chief of IEEE Transactions on Software Engineering and of the Automated Software Engineering Journal, and chaired the Steering Committee of the International Conference on Software Engineering (ICSE). He received an ICSE Most Influential Paper Award, a Philip Leverhulme Prize, an Automated Software Engineering Fellowship, and a Senior Research Fellowship of the Royal Academy of Engineering. His research work crosses a number of discipline boundaries in computing, and he has received best paper or artefact awards in Software Engineering, Logic Programming, Human-Computer Interaction, Natural Language Processing, and Security & Privacy (e.g. recent best paper at TrustCom 2014). He currently holds a Royal Society-Wolfson Merit Award and a European Research Council (ERC) Advanced Grant on Adaptive Security and Privacy, and is the recipient of the 2015 ACM SigSoft Distinguished Service Award .

Title: Secure Data Deduplication in Cloud Environments

Abstract: With the tremendous growth of available digital data, the use of Cloud Service Providers (CSPs) for storage are gaining more popularity, since these types of services promise to provide convenient and efficient storage services to end-users by taking advantage of a new set of benefits and savings offered by cloud technologies in terms of computational, storage, bandwidth, and transmission costs. In order to achieve savings in storage, CSPs often employ data deduplication techniques to eliminate duplicate data. However, benefits gained through these techniques have to be balanced against users' privacy concerns, as these techniques typically require full access to data. In this talk, we present solutions for different data types (text, image and video) for secure data deduplication in cloud environments. Our schemes allow users to upload their data in a secure and efficient manner such that neither a semi-honest CSP nor a malicious user can access or compromise the security of the data. We use different image and video processing techniques, such as data compression, in order to further improve the efficiency of our proposed schemes. The security of the deduplication schemes is obtained by applying suitable encryption schemes and error correcting codes. Moreover, we propose proof of storage protocols including Proof of Retrievability (POR) and Proof of Ownership (POW) so that users of cloud storage services are able to ensure that their data has been saved in the cloud without tampering or manipulation.
