Abstract
This paper deals with the problem of privacy issues caused by the tracking activities of web advertisers. Web advertisers place cookies in the browser to track users' surfing behaviour across websites, mostly without his knowledge or consent. This paper proposes a fine-grained, per-site cookie management protocol. We implement our proposal as Mozilla Firefox add-on and we call it TTPCookie. We evaluate the add-on on a data-set obtained from automated visits of 5000 websites. Further, Mozilla Firefox add-ons and other related proposals dealing with cookies and privacy are analysed and compared.
