Karl Wabst on 21 May 09Social networking sites are often used by government ministers as an example of the profound way attitudes to privacy have changed. They argue that the young generation invade their own privacy to a far greater extent than the government ever would. The implication is that the older people who object to government intrusion are living in the past. The response to this is that people who use social networking sites voluntarily reveal things about themselves and have a degree of control of over how long information and photographs stay in the public domain, while the government collects and stores information without permission and allows the subject no access to the data held. There is no obvious comparison between the two activities. But this doesn't let the social networking sites off the hook. Most internet companies claim a kind of morality free status when it comes to such issues as privacy and copyright, and Web 2.0 sites are no different. A study published this week by Cambridge PhD students shows that nearly half of all social networking sites retain copies of photographs after being "deleted" by users. The study examined 16 popular websites that host user-uploaded photos, including social networking sites, blogging sites and dedicated-photo-sharing sites. Seven of the 16 sites surveyed were still maintaining copies of users' photos after they had been deleted by the user. The researchers - Jonathan Anderson, Andrew Lewis, Joseph Bonneau and lecturer Frank Stajano - found that by keeping a note of the URL where the photo is actually stored in a content delivery network, it was possible for them to access the photo even after it had been deleted.
