ABSTRACT

                   In mobile social networks, the mobile users may, however, face the risk of leaking

their personal information and location privacy. the secure friend discovery process as a

generalized privacy-preserving interest and prole matching problem. We identify a new security

threat arising from existing secure friend discovery protocols, coined as runaway attack, which

can introduce a serious unfairness issue. we introduce a novel blind vector transformation

technique, which could hide the correlation between the original vector and transformed results.

our privacy-preserving and fairness-aware interest and prole matching protocol, which allows one

party to match its interest with the prole of another, without revealing its real interest and prole

and vice versa. Our work is motivated from a simple observation that if two vectors match, they

will still match no matter whether they are transformed in the same way.
