Neighborhood Watched? Each time I read about our “loss of privacy,” such as in Daniel J. Solove’s examination of effects of social-networking sites [“The End of Privacy?”], it makes me laugh. People seem often to confuse privacy with anonymity, which we invented only a few generations ago. Earlier, most Americans lived in small towns or villages, which provide limited privacy and no anonymity. The rise of big cities gave us anonymity, which lets some of us do things we would probably not have done in the villages, where there wasn’t much crime because no one was unknown. That social control was just waiting to be replaced, so now our villagers are electronic.   Sheri S. Tepper Santa Fe, N.M. SOLOVE REPLIES: There is a key difference between the small towns of yesteryear, where everybody knew your name, and the sprawling “global village” of today. In small towns, people knew one another well; they could judge one another in context. Today, in our more anonymous life, we often judge people based on information fragments without context. This is a much more impoverished way to understand and judge others, and the information we have about them is far more dubious. The idyllic image of the small village cannot be re-created through modern electronic technology. Moreover, a brief dip into 19th-century history and literature shows a world rife with oppressive norms, nosy neighbors and communities ready to condemn, often unfairly. Although social control can be good, not all of it is, and sometimes it can be downright unfair, stifling, misguided and cruel. Animal Ethics “Primate Motions,” by Lizzie Buchen [News Scan], reports on a Swiss ruling denying two neuroscientists’ applications to experiment on macaques on the basis that their proposals did not have sufficient expected benefits to society. In criticizing strict regulation on primate research, these scientists and others interviewed seem only interested in research, with no sense of moral duty. As people of science, we must be absolutely certain that the animals we use are treated as compassionately as possible, and we must be thankful to them for the knowledge they afford us. Bassam Salim Boston Tagging Trouble? The article “RFID Tag—You’re It,” by Katherine Albrecht, continued an important discussion around privacy and radio-frequency identification (RFID) that EPCglobal has been addressing for some time. But it is important to remind readers that the majority of RFID tags do not store or collect personal information. Just like ubiquitous barcodes, the electronic product code (EPC) carried by a tag is a string of numbers that identifies only a thing—typically the tag itself—not a person. The author’s claim that anyone with an RFID reader can skim tags is therefore pointless—skimming would provide neither personal information nor access to it. This emerging technology is a powerful tool with the potential to improve the safety, security, and availability of food, medicine and other products, providing tremendous societal benefits. To learn more about RFID and EPC and to see our full privacy guidelines, readers can visit http://aboutepc.org Elizabeth Board EPCglobal Public Policy Steering Committee Albrecht paints a broad picture of RF technologies and their privacy risks. RFID tags based on the EPCglobal standard EPC Gen 2 are different from chips that comply with international ID card standards ISO/IEC 7816 and ISO/IEC 14443. The Smart Card Alliance has long stated that EPC Gen 2 RFID tags can pose significant risks to privacy and are not appropriate for identity applications. EPC Gen 2 RFID tags were designed to enable tracking, have minimal or no security, and are readable from up to 10 meters away. RF-enabled smart cards contain a fully functioning microprocessor and can deliver security such as public-key cryptography, mutual authentication and encrypted communications. They operate over a 10-centimeter range to prevent tracking or eavesdropping. Randy Vanderhoof Smart Card Alliance Basis of the Bulge In “A Solar Big Gulp” [News Scan], David Appell refers to an analysis concluding that in billions of years, as the sun loses mass and expands, its rotation rate will slow down, creating a tidal bulge on its surface whose gravity will pull Earth inward. A tidal bulge, however, is not caused by rotation but by differential gravitation from an external body. David C. Halley via e-mail APPELL REPLIES: Halley is right: an external body, not rotation, causes a tidal bulge. But only when the sun’s rotation is very small or nonexistent does its tidal bulge lag behind Earth in orbital motion, pulling Earth back in its orbit, taking energy out of Earth’s orbital motion and causing the planet to spiral inward. Otherwise, with rapid rotation, the bulge is ahead of Earth, which would be pulled forward and spiral outward (as happens to the moon in the Earth-moon system).
