In this paper, we consider the private information retrieval using multiple databases with multiple messages in the case where information leakage is allowed. In this private information retrieval, a different restriction is given to each database regarding information leakage from a query about which message was searched. In this paper, under this restriction, we give upper and lower bounds on the capacity which is the maximum number of bits of the desired message per bit of received information from databases. |
