Quantum　private　comparison　(QPC)　is　the　quantum　method　that　can　compare　the　equality　of　the　distrustful　participants’　private　information　without　leaking　them.　The　4-particle　cluster　state　has　a　strong　violation　of　local　reality　and　shows　to　be　robust　against　decoherence　than　any　other　4-particle　state.　In　this　paper,　a　new　efficient　QPC　protocol　based　on　the　entanglement　swapping　between　the　4-particle　cluster　state　and　Bell　state　has　been　proposed.　With　the　pre-shared　secret　key　sequence　between　the　two　participants,　the　semi-honest　third　party　(TP)　can　only　execute　the　protocol’s　processes　without　obtaining　information　about　the　participants’　secrets　and　the　final　comparison　results.　Then,　we　show　that　the　proposed　QPC　protocol　is　secure　against　outside　or　participant　attacks　and　more　efficient　than　similar　literature.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
