Abstract

This chapter presents the concept of decentralized spatial computing (DeSC) as a way to embed dynamic spatial data capture and processing capabilities within our built urban environment. The chapter illustrates the potential of DeSC for safe- guarding privacy in a dynamic location-based services scenario: Mobile service users protect their potentially sensitive location by the use of a decentralized query algorithms, solely collaborating with peers close by and thereby excluding the privacy bottleneck of an omniscient global service provider. In an extensive set of consecutive experiments several decentralized query algorithms were tested, trading the level of privacy for the quality of service. The use of a real world test bed, — a small part of Ordnance Survey’s OS MasterMap® Integrated Transport Network™ Layer for Southampton — underlines the experiments’ validity. The chapter concludes with a research and development agenda for DeSC in the urban context.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
