| Abstract: | Recently, a small group of computer scientists has been taking a different tack,they are building software tools that promise to keep names, addresses, health status and other information secret while allowing patterns to emerge within large data sets that can help predict broad social trends, buying behavirors or massive health or terrorist threats. Some of this software has been patented and used by government agencies in the U.S; other algorithms are several years from practical implementation.Some of the existing tools enhance anonymity.For example,the freedom browser from Zero-Knowledge System lnc.in Montreal prevents sending of personal information over an internet connection without the user's consent.The techniques under development can change personal and private data in various ways,including making personal information anonymous,possibly using cryptography or by disguising it in other ways,For example, researchers at the IBM Privacy Research Institute in San Jose are perfecting an approach that"andomizes data before it is communicated. |
