Secure Multiparty Protocols

Abstract

Secure Multiparty Computation (SMC) protocols are one of the first techniques
used in privacy preserving data mining in distributed environments. The protocol does not
reveal anything other than the output of the function or anything that can be computed
from it in polynomial time. Moreover, the protocol does not require a trusted third party.
The main focus of this paper is to design the look ahead approach for SMC protocol with
the help of distributed k-anonymity technique. These protocols prevent information
disclosure other than the objective function. People are jointly conducting computation
tasks based on the private inputs they each supplies. These computations could occur
between mutually un-trusted parties, or even between Secure Multiparty Computations
(SMC). The look-ahead operation is highly localized and its accuracy depends on the
amount of information the parties are willing to share.
