In this paper, a quantum private comparison protocol with Bell states is proposed. In the protocol, two participants can determine the relationship between their secret inputs in size, with the assistance of a semi-trusted third party. The presented protocol can ensure fairness, correctness, and security. Meanwhile, all the particles undergo only a one-way trip, which improves the efficiency and security of the communication. Furthermore, only Bell states are exploited in the implementation of the protocol, and two participants are just required having the ability to perform single particle operations, which make the presented protocol more feasible in technique.
