A quantum private comparison (QPC) protocol enables two parties to securely compare their data without disclosing the actual values one another, utilizing mechanics maintain confidentiality. Many current QPC protocols mainly concentrate on comparing equality of information between users during a single execution, which restricts scalability. To overcome this limitation, we present an efficient aimed at evaluating groups in execution. This is achieved by leveraging entanglement correlations each particle four-particle cluster state. In our approach, encode using bit flip or phase shift operators sequence they receive, then sent back semi-trusted party determines whether secrets are equal and communicates results users. By employing method facilitating distributed transmission sequence, achieves qubit efficiency 50%. Security analyses reveal that neither external attacks nor insider threats can successfully compromise confidentiality data.

In this paper, we introduce a two-party quantum private comparison (QPC) protocol that employs single photons as resources and utilizes rotational encryption to safeguard the privacy of inputs. This enables two parties compare their data without disclosing any information beyond outcome comparison. The participants’ are encoded photons, which encrypted using method. These then transmitted semi-honest third party (TP), who conducts single-particle measurements determine if users’ equal subsequently announces results participants. By harnessing principles mechanics, ensure robust protection against potential eavesdropping participant attacks. contrast numerous existing QPC protocols rely on multi-qubit or d-dimensional states, our method exhibits superior efficiency practicality. Specifically, achieves qubit 50% by one bit classical information, easier prepare than states.
