Privacy Protection through Query Rewriting in Smart Environments
نویسندگان
چکیده
By the events in the past years, the integration of data protection mechanisms into information systems becomes a central research problem again. In this poster, we show how query rewriting can be used to maintain privacy of users in smart (or assistive) environments. We developed a privacy respecting query processing and a vertical fragmentation of queries, processing maximal parts of the query as close to the sources of the data (e.g. sensors) as possible.

متن کاملA Comparative Study of Privacy Protection Methods for Smart Home Environments
Due to the importance of privacy protection for smart home environments, there have been numerous propositions, to support event source anonymity using fake data transmissions and delays. Among them, periodic and probabilistic distribution-based transmission methods achieve near perfect privacy while sacrificing real time transmission of detected event data. In this paper, we aim to study the p...
