Abstract: Personalized web search (PWS) has showed its effectiveness in improving the quality of search services on the Internet. However, evidences show that users’ fear to disclose their private information during search has become a major barrier for the wide proliferation of PWS. Here we are introducing the concept of Homomorphic encryption to encrypt the server such a way that an eavesdropper nor an untrusty admin could access the search words and the profile. It is less complex and more efficient than the UPS framework.
