Privacy-Preserving Similarity-Based Text Retrieval
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. In this a...

sg-smu-ink.sis_research-12192017-03-23T07:10:43Z Privacy-Preserving Similarity-Based Text Retrieval PANG, Hwee Hwa SHEN, Jialie Krishnan, Ramayya 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. In this article, we introduce a privacy-preserving, similarity-based text retrieval scheme that (a) prevents the server from accurately reconstructing the term composition of queries and documents, and (b) anonymizes the search results from unauthorized observers. At the same time, our 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. 2010-02-01T08:00:00Z text application/pdf https://ink.library.smu.edu.sg/sis_research/220 info:doi/10.1145/1667067.1667071 https://ink.library.smu.edu.sg/context/sis_research/article/1219/viewcontent/Privacy_Preserving_Similarity_Based_Text_Retrieval__edited_.pdf http://creativecommons.org/licenses/by-nc-nd/4.0/ Research Collection School Of Computing and Information Systems eng Institutional Knowledge at Singapore Management University Privacy of search queries Security in text retrieval Singular value decomposition Databases and Information Systems Numerical Analysis and Scientific Computing |
