In this paper, a novel multi-party quantum private comparison (MQPC) protocolwith a semi-honest third party (TP) is proposed based on the entanglementswapping of d-level cat states and d-level Bell states. Here, TP is allowed tomisbehave on his own but will not conspire with any party. In our protocol, nparties employ unitary operations to encode their private secrets and cancompare the equality of their private secrets within one time execution of theprotocol. Our protocol can withstand both the outside attacks and theparticipant attacks on the condition that none of the QKD methods is adopted togenerate keys for security. One party cannot obtain other parties' secretsexcept for the case that their secrets are identical. The semi-honest TP cannotlearn any information about these parties' secrets except the end comparisonresult on whether all private secrets from n parties are equal.
