An Exploratory Analysis of Leaked Facebook Data: A Case of Turkish Users

Abstract

In this study, an analysis is performed on recently leaked data of Turkish Facebook users to inspect their sharing behavior along with how accurately an adversary can perform attacks to learn the gender and username of a user. Experimental results show that the majority of users do not disclose their sensitive data except for phone numbers. Users mostly live in big cities, but privacy-aware users mostly live in the eastern and southeastern parts of the country. It is also possible to infer gender with very high accuracy up to 0.95 just using the first name and username of a user.
