摘要：
We present a new quantum private comparison protocol based on the three-particle GHZ states. In this protocol, we prepare two types of GHZ states and use their entanglement properties to encode and compare the private information of X and Y. We also discuss that our protocol can withstand all various kinds of outside attacks and participant attacks.
