User Identification and Anonymization in 802.11 Wireless LANs

Privacy issues have been a serious concern for 802.11Wireless LAN users. Prior research on privacy issues usually focuses on pseudonym techniques, where the unique, consistent explicit identifiers such as MAC addresses from the users can be frequently changed, and thus it is challenging to track users through those always changing identifiers. However, recent research done by Pang et al. has demonstrated that pseudonyms are not adequate to protect user privacy. The key idea of Pang et al.'s method is to locate implicit identifiers (e.g., IP addresses and port numbers a user frequently visits), build user behavior patterns based on these implicit identifiers, and then apply classification techniques to identify users.
