Twitter was first launched in March 2006 with the first tweet ever being “just setting up my twttr” by Jack Dorsey, co-founder of the oh-so-famous microblogging website.

As we all known an understand, the teens are the trend-setters when it comes to social networking, and according to the latest report from the Pew Research Center, the teens are turning to Twitter more often than to Facebook.

De-anonymize Twitter accounts
The University of Texas Researchers have shown that they can “de-anonymize” Twitter accounts based on anonymous social network topology and a bit of outside Fickr data. Back in 2007, they performed a similar trick with anonymized Netflix data and they say the lesson is clear: “anonymity is not sufficient for privacy” on the web.
Arvind Narayanan and his advisor Vitaly Shmatikov’s newest paper, “De-anonymizing social networks”, is another attack on the idea that data can be easily anonymized by stripping out a few bits of personally identifiable information (PII). Most of their work over the years is built on premise that PII extends far beyond names and address; in many datasets, the very structure of the data provides all sorts of clues that can be deciphered with only a few bits of information.
Narayanan and Shmatikov in “De-anonymizing social networks”, take an anonymous graph of the social relationships established through Twitter and find that they can actually indentify many Twitter accounts based on an entirely different data source, in this case, Flickr.
