Privacy and False Identification Risk in Geomasking Techniques

Recent years have seen an increase in location privacy research, including the application of geomasking procedures. Geographical masks aim to protect privacy and preserve spatial information through the displacement of point data. False identification, or the mistaken association of data with the incorrect person or household, is an unexplored issue in geomasking, despite legal protections against false association. This study introduces a topological framework for assessing identification risk and examines the risk of false identification in four masking techniques: random perturbation, donut masking, and the newer Voronoi and MGRS masking techniques. While Voronoi masking is found to best preserve the clustering properties of a sample of urban foreclosure data, the other three masking techniques result in better protection against correct and false identification.     

Outsourcing Regulation: Analyzing Nongovernmental Systems of Labor Standards and Monitoring

A range of new nongovernmental systems for advancing labor standards and enforcement have emerged over the last 5 years. This article comparatively assesses these multistakeholder systems of codes of conduct and monitoring, discusses their underlying models of regulation, and proposes a set of criteria for evaluating their effectiveness, including their legitimacy, rigor, accountability, and complementarity. Critical issues are raised about the transparency of existing initiatives, independence of monitors, convergence of standards, and dynamics among nongovernmental regulation, unions, and state enforcement. The article concludes by arguing that with increased transparency, improved technical capacities, and new mechanisms of accountability to workers and consumers, nongovernmental monitoring could complement existing state regulatory systems.     

American digger and archaeology (Respond to this article at http://www.therai.org.uk/at/debate)

This editorial reflects on the nature of public archaeology. It looks at the relationship archaeologists have with popular TV, focusing in particular on the new series American digger by Spike TV, and Diggers by National Geographic, and reflects on the relationship archaeologists have with amateurs using metal detectors to uncover treasures.
