SPRINGL 2009 workshop report: the 2nd international workshop on security and privacy in GIS and LBS (Seattle, Washington - November 3, 2009)
No full textForeword for the special issue of selected papers from the 3rd ACM SIGSPATIAL Workshop on Security and Privacy in GIS and LBS
Full text linkThe third Workshop on Security and Privacy in GIS and LBS (SPRINGL 2010) was organized in November 2, 2010, San Jose, California in conjunction with the SIGSPATIAL International Conference on Advances in Geographic Information Systems (ACM GIS 2010). Security and privacy are the two dimensions of GIS systems and geospatial applications that need to be addressed for these applications to have wider acceptance. However, we are still far from fully achieving this goal with provable techniques that can be adopted by the industry. The SPRINGL workshop series aims to provide a forum for researchers working in the field of geospatial data security and privacy to discuss the advances in this domain.
In order for solid archival work to be presented to the community, special issues of Transactions on Data Privacy have been organized for the previous SPRINGL workshops. This special issue contains three extended papers that have been selected from the papers presented at SPRINGL 2010 focusing mainly on the privacy aspects

SPRINGL 2010 Workshop report
No full textSecurity and privacy are both critical for geospatial applications because of the dramatic increase and dissemination of geospatial data in several application contexts including homeland security, environmental crises, and natural and industrial disasters. Furthermore, geospatial infrastructures are being leveraged by companies to provide a large variety of location-based services (LBS) able to tailor services to users. However, despite the increase of publicly accessible geospatial information little attention is being paid to securing geospatial information systems (GIS) and LBS. Privacy is also of increasing concern given the sensitivity of personally-identifiable location information
Springl! : proceedings of the 3rd ACM SIGSPATIAL International Workshop on security and privacy in GIS and LBS, November 2, 2010, San José, California, USA /
No full textThese proceedings contain the papers selected for presentation at the third edition of the ACM Workshop on Security and Privacy in GIS and LBS (SPRINGL 2010) which is being held in conjunction with the ACM SIGSPATIAL GIS conference like previous SPRINGL workshops. Geospatial data has many application areas including traffic management, homeland security, geo-marketing, and environmental crises management which motivate the research in this area. However, growing geospatial information is yet to be matched by the advances in secure geospatial information systems (GIS) and LBS. On the other hand, location information is very sensitive and also a strong quasi-identifier, which can be combined with other rich information sources to cause serious privacy leaks. Therefore ensuring security and privacy in GIS and LBS is of utmost importance which needs to be properly addressed within the research community and then to be transferred into technology. The aim of SPRINGL is to bring together the researchers working on geospatial data security and privacy to discuss and present recent advances in this area. We hope that these proceedings will serve as a valuable reference for researchers and practitioners to motivate further research and development in geospatial data security and privacy. This year's program is organized in three sessions: (1) Security, (2) Privacy of movement, and (3) Applications and Requirements. The program also features an outstanding invited speaker, Matt Duckham from University of Melbourne, with his talk on "Moving forward: location privacy and location-awareness"

Privacy issues in location-aware browsing
Full text linkAdvances in positioning services and their pervasiveness, e.g., wi- based location services, pave the way to the development of innovative LBSs and architectures. In this paper
we focus on location-aware browsing, a framework which enables websites to acquire the position of website users. In particular we discuss privacy issues related to the recent
W3C proposal for a geolocation API standard. Such specication prescribes that users must give explicit consent to the disclosure of position information to websites. In this
paper we argue that stronger and more exible protection is needed: a) users should be provided with the capability of disclosing coarse regions in place of point coordinates in
order to limit the disclosure of personal location data; b) location information should be protected not only against websites but also against location service providers. We dis-
cuss a possible approach to address those requirements under the assumption that the position is computed by a wibased positioning service. Finally, we broaden the discussion
to include a complementary legal viewpoint
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
