Multi-party summation query method based on differential privacy

Abstract

Differential privacy is considered to be a very reliable protection mechanism because it does not require the a prior knowledge for the attacker. However, differential privacy is rarely used in a multi-party environment. In view of this, the differential privacy is applied to the data summation query in multi-party environment. This method was described in detail and proved the security of the method.
