Privacy of Web surfers nowadays is frequently compromised by eavesdroppers. The threat applies to surfers’ identities, the World Wide Web (hereafter: the Web) site being browsed, and their association. This article provides a comprehensive review of AET for the Web. First, the article examines the nature of threats to anonymity. Next, theoretical and practical solutions for protecting surfers’ anonymity are presented and their capabilities are extracted. The solutions are then analyzed and mapped with regards to their performance and the degree of anonymity they cater for. The analysis clearly demonstrates the inherent trade-off between performance and anonymity provided by AET.
