Privacy protection without impairing personalization by using the extended system MASKS and the extended contextualized P3P privacy policies

摘要

Current privacy protection mechanisms are limited to provide privacy guarantees for Web data gathering. MASKS system provides user's anonymity and allowance for implicit data collection, although it lacks security for collecting explicit data. It does not allow browsing session by dividing cookies into different groups of interest. Project 3P introduces a mechanism to keep users aware of privacy policies while navigating through the sites. It offers low reliability for implicit data gathering. Thus, developing a system to combine an extended MASKS system and an extended P3P ensures existing qualities of both mechanisms and supplies each other's limitations. The extended MASKS system includes sessions in the masking proxy to enable browsing session creation. The extended P3P incorporates information about user's benefits by increasing his/her understanding on privacy practices. Running comparative tests with users allows an evaluation on advantages by using this new combined system. The results showed that the combined system provides users' navigation with higher reliability. Thus, the implementation of this system proves useful for providing privacy during Web browsing, without impeding data gathering.
