NSA beschn�ffelt Soziale Software

--- Dass es im Bereich Sozialer Software (PDF-Datei), dem Lieblingskind der Web-2.0-Verfechter, einige Datenschutzprobleme gibt, ist nicht ganz neu. Der New Scientist berichtet aber nun, dass das die Ober-US-Schn�ffler ein Auge auf das Social Networking im Netz geworfen und Online-Communities als Jagdgrund f�r Spionageaktivit�ten auserkoren haben:
"I AM continually shocked and appalled at the details people voluntarily post online about themselves." So says Jon Callas, chief security officer at PGP, a Silicon Valley-based maker of encryption software. He is far from alone in noticing that fast-growing social networking websites such as MySpace and Friendster are a snoop's dream. New Scientist has discovered that Pentagon's National Security Agency, which specialises in eavesdropping and code-breaking, is funding research into the mass harvesting of the information that people post about themselves on social networks. And it could harness advances in internet technology - specifically the forthcoming "semantic web" championed by the web standards organisation W3C - to combine data from social networking websites with details such as banking, retail and property records, allowing the NSA to build extensive, all-embracing personal profiles of individuals. ... the NSA is pursuing its plans to tap the web, since phone logs have limited scope. They can only be used to build a very basic picture of someone's contact network, a process sometimes called "connecting the dots". Clusters of people in highly connected groups become apparent, as do people with few connections who appear to be the intermediaries between such groups. The idea is to see by how many links or "degrees" separate people from, say, a member of a blacklisted organisation. By adding online social networking data to its phone analyses, the NSA could connect people at deeper levels, through shared activities, such as taking flying lessons. Typically, online social networking sites ask members to enter details of their immediate and extended circles of friends, whose blogs they might follow. People often list other facets of their personality including political, sexual, entertainment, media and sporting preferences too. ... No plan to mine social networks via the semantic web has been announced by the NSA, but its interest in the technology is evident in a funding footnote to a research paper delivered at the W3C's WWW2006 conference in Edinburgh, UK, in late May. That paper, entitled Semantic Analytics on Social Networks, by a research team led by Amit Sheth of the University of Georgia in Athens and Anupam Joshi of the University of Maryland in Baltimore reveals how data from online social networks and other databases can be combined to uncover facts about people. The footnote said the work was part-funded by an organisation called ARDA. What is ARDA? It stands for Advanced Research Development Activity. According to a report entitled Data Mining and Homeland Security, published by the Congressional Research Service in January, ARDA's role is to spend NSA money on research that can "solve some of the most critical problems facing the US intelligence community".
