| Abstract: | Users of online services are increasingly wary that their activities could disclose confidential
information on their business or personal activities. It would be desirable for an online document
service to perform text retrieval for users, while protecting the privacy of their activities. A New
similarity-based text retrieval scheme that prevents the server from accurately reconstructing
the term composition of queries and documents, and anonymizes the search results from
unauthorized observers. At the same time, this scheme preserves the relevance-ranking of the
search server, and enables accounting of the number of documents that each user opens. The
effectiveness of the scheme is verified empirically with two real text corpora. |
