Keine Anonymität bei “Web 2.0 Diensten”

ITWorld berichtet, dass Forscher der University of Texas in Austin ein Verfahren entwickelt haben, um (ohnehin nur vermeintlich) anonyme User in sozialen Netzen und Diensten – dazu gehört auch Twitter – zu identifizieren:

Web site operators often share data about users with partners and advertisers after stripping it of any personally identifiable information such as names, addresses or birth dates. Arvind Narayanan and fellow researcher Vitaly Shmatikov found that by analyzing these “anonymized” data sets, they could identify Flickr users who were also on Twitter about two-thirds of the time, depending on how much information they have to work with.
