Geolocation of data in the cloud
Proceedings of the third ACM conference on Data and application security and privacy, 2013We introduce and analyze a general framework for authentically binding data to a location while providing strong assurances against cloud storage providers that (either accidentally or maliciously) attempt to re-locate cloud data. We then evaluate a preliminary solution in this framework that combines constraint-based host geolocation with proofs of ...

Deriving Geolocations in Wikipedia
Proceedings of the 29th ACM International Conference on Information & Knowledge Management, 2020We study the problem of deriving geolocations for Wikipedia pages. To this end, we introduce a general four-step process to location derivation, and consider different instantiations of this process, leveraging both textual and categorical data. Extensive experimentation shows that our methods provide good precision-recall trade-offs and improvements ...

Whois Based Geolocation: A Strategy to Geolocate Internet Hosts
2010 24th IEEE International Conference on Advanced Information Networking and Applications, 2010There are several strategies in the literature to geolocate Internet hosts, however the accuracy of their estimates is a common issue. Furthermore, accurate Internet host location remains a challenge due to incomplete domain registers. In this paper, we propose a classification for geolocation strategies and present the Whois Based Geolocation (WBG ...

Radio interferometric geolocation
Proceedings of the 3rd international conference on Embedded networked sensor systems, 2005We present a novel radio interference based sensor localization method for wireless sensor networks. The technique relies on a pair of nodes emitting radio waves simultaneously at slightly different frequencies. The carrier frequency of the composite signal is between the two frequencies, but has a very low frequency envelope.

Geolocation in the Semantic BIM
2019 IEEE International Conference on Engineering, Technology and Innovation (ICE/ITMC), 2019Building codes are the rules and guidelines that specify the minimum acceptable level of safety, accessibility, general welfare, etc. of building models. Code compliance checking of building models requires precise identification or estimation of the real-world geographic location of IFC objects.
