| Abstract(in English) | We examine the database privacy of similarity based ranking for a database of private records where each record and queries for similarity search are both represented by a fixed size bit vector. In our setting, the database answer record indexes are arranged in descending order according to similarity to the query. This setting can be widely applied, including for retrieval from private records, because ranking is often used for information retrieval and many types of data can be expressed as bit vectors. In this paper, we examine privacy breaches caused by ranked indexes and differentially private ranked indexes. |
