Show me how you play and I will tell you who you are
Résumé
Can a chess player play anonymously in the Internet? This question is critical for all tournament players: games are collected and gathered on online database. Identifying a player is "only" a problem of data mining, i.e. players characterization, pattern matching, and hypoth- esis testing. This abstract presents the general issues in the analysis and identification of a chess player. The problem depicted has consequences for many other domains in which privacy can be jeopardized. Chess is certainly the Drosophila of privacy for online games.
