The emergence of social media (networks, blogs, web forums) has given people numer-ous opportunities to share their personal sto-ries, including details of their health. Although users mostly post under assumed nicknames, state-of-the-art text analysis techniques can combine texts from different media and use that linkage to identify private details of an in-dividual‟s health. In this study we aim to em-pirically examine the accuracy of identifying authors of on-line posts on a medical forum. 1 Our results show a high accuracy of the au-thorship attribution, especially when text is represented by the orthographical features. 1
