Information Security South Africa (ISSA) 2010

An ISSA conference talk is summarized, offering an introductory view of online privacy from a security lens: it defines privacy as data with implied access controls and authorized use, then surveys techniques that enable pervasive collection and inference of personal data (tracking pixels/cookies, CSS history probing, search-log exposure, deanonymization via public datasets and tools like Maltego, and social-network metadata analysis), concluding with brief implications and high-level defenses.
