A new model for privacy preservation named Hidden-web Privacy Preservation Surfing (Hi-WePPS) is proposed.

The basic assumption motivating this proposal was that such websites cannot be trusted to preserve their surfers’ privacy since site owners know the identities of their users and can monitor their activities.

The noise is generated by submitting fake requests providing wrong data to the automatic programs collecting data about the users. A prototype of Hi-WePPS is being developed for preserving a surfer’s privacy while accessing the U.S. patent office site (www.uspto.gov). This prototype …
