Unraveling Privacy: The Personal Prospectus and the Threat of a Full-Disclosure Future

Information technologies are reducing the costs of credible signaling, just as they have reduced the costs of data mining and economic sorting. The burgeoning informational privacy field has ignored this evolution, leaving it unprepared to deal with the consequences of these new signaling mechanisms. In an economy with robust signaling, those with valuable credentials, clean medical records, and impressive credit scores will want to disclose those traits to receive preferential economic treatment. Others may then find that they must also disclose private information to avoid the negative inferences attached to staying silent. This unraveling effect creates new types of privacy harms, converting disclosure from a consensual to a more coerced decision. This Article argues that informational privacy law must focus on the economics of signaling and its unraveling of privacy

Telecommunication reforms, access regulation, and Internet adoption in Latin America

The authors review the stylized facts on regulatory reform in telecommunications and its effects on telecommunications development and Internet penetration in Latin America. Relying on data from the International Telecommunication Union, the Information for Development Program (InfoDev), and the World Bank for 1990-99, the authors then test econometrically the determinants of the differences in Internet penetration rates across Latin America. The results show that effective implementation of the reform agenda in telecommunications regulation could accelerate adoption of the Internet in Latin America-even though it is only part of the solution (income levels, income distribution, and access to primary infrastructure are the main determinants of growth in Internet connections and use). Regulation will work by cutting costs. Cost cutting will require that regulators in the region take a much closer look at the design of interconnection rules and at the tradeoffs that emerge from the complex issues involved. It will also require a commitment to developing analytical instruments, such as cost models, to sort out many of the problems. Appropriate cost models will generate benchmarks that are much more consistent with the local issues and with the local cost of capital than international benchmarks will ever be for countries in unstable macroeconomic situations. Cost cutting will require an equally strong commitment to imposing regulatory accounting systems that reduce the information asymmetrics that incumbents use to reduce the risks of entry. All these changes will ultimately require a stronger commitment by competition agencies, since in many countries a failure to negotiate interconnection agreements will raise competition issues just as often as it will raise regulatory questions.Rural Communications,Information Technology,Telecommunications Infrastructure,Knowledge Economy,Health Monitoring&Evaluation,Knowledge Economy,Information Technology,Health Monitoring&Evaluation,Rural Communications,Education for the Knowledge Economy

Posters and Development: A Case Study of Cell Phone Posters in the Rural Congo

One of the benchmarks of the information age often forgotten is the proliferation of posters or billboards in and around workplaces, neighborhoods, airports, shopping centers, restaurants, theaters, libraries, schools, etc. More interestingly, through cell phones, posters are rapidly entering rural areas in developing countries. Although these posters come with specific messages and graphics – continually upgraded and tailored to people’s attention -- they hardly undergo scientific inquiry in circles concerned with information and communication technologies [ICTs]. The lack of attention raises questions on the role of information systems and related wireless devices being deployed in developing countries. The present paper aimed to canvass cell phone posters and unbundle the underlying practices and routines. As well as positioning posters at the center stage of ICT research, the present paper applied critical discourse analysis to inquire into ways in which development was represented or effected among populations in the rural Congo. The paper determined that posters were not centered on local populations and their day-to-day struggles/needs, and that the information conveyed on posters was not geared toward the development of the world’s poorest. The paper crafted some paths for future work in ICT fields and cell phone bodies of work

Constructing elastic distinguishability metrics for location privacy

With the increasing popularity of hand-held devices, location-based applications and services have access to accurate and real-time location information, raising serious privacy concerns for their users. The recently introduced notion of geo-indistinguishability tries to address this problem by adapting the well-known concept of differential privacy to the area of location-based systems. Although geo-indistinguishability presents various appealing aspects, it has the problem of treating space in a uniform way, imposing the addition of the same amount of noise everywhere on the map. In this paper we propose a novel elastic distinguishability metric that warps the geometrical distance, capturing the different degrees of density of each area. As a consequence, the obtained mechanism adapts the level of noise while achieving the same degree of privacy everywhere. We also show how such an elastic metric can easily incorporate the concept of a "geographic fence" that is commonly employed to protect the highly recurrent locations of a user, such as his home or work. We perform an extensive evaluation of our technique by building an elastic metric for Paris' wide metropolitan area, using semantic information from the OpenStreetMap database. We compare the resulting mechanism against the Planar Laplace mechanism satisfying standard geo-indistinguishability, using two real-world datasets from the Gowalla and Brightkite location-based social networks. The results show that the elastic mechanism adapts well to the semantics of each area, adjusting the noise as we move outside the city center, hence offering better overall privacy

Privacy as a Public Good

Privacy is commonly studied as a private good: my personal data is mine to protect and control, and yours is yours. This conception of privacy misses an important component of the policy problem. An individual who is careless with data exposes not only extensive information about herself, but about others as well. The negative externalities imposed on nonconsenting outsiders by such carelessness can be productively studied in terms of welfare economics. If all relevant individuals maximize private benefit, and expect all other relevant individuals to do the same, neoclassical economic theory predicts that society will achieve a suboptimal level of privacy. This prediction holds even if all individuals cherish privacy with the same intensity. As the theoretical literature would have it, the struggle for privacy is destined to become a tragedy. But according to the experimental public-goods literature, there is hope. Like in real life, people in experiments cooperate in groups at rates well above those predicted by neoclassical theory. Groups can be aided in their struggle to produce public goods by institutions, such as communication, framing, or sanction. With these institutions, communities can manage public goods without heavy-handed government intervention. Legal scholarship has not fully engaged this problem in these terms. In this Article, we explain why privacy has aspects of a public good, and we draw lessons from both the theoretical and the empirical literature on public goods to inform the policy discourse on privacy
