  In this paper, a novel semiquantum private comparison (SQPC) protocol based
on single kind of Bell states is proposed, which allows two classical parties
to judge the equality of their private inputs securely and correctly under the
help of a semi-honest third party (TP) who possesses complete quantum
capabilities. TP is allowed to misbehave on her own but cannot conspire with
anyone else. Our protocol needs none of unitary operations, quantum
entanglement swapping or the reordering operations. Moreover, our protocol only
needs to prepare single kind of Bell states as initial quantum resource.
Detailed security analysis turns out that our protocol is secure against
various outside and participant attacks. Compared with most of the existing
SQPC protocols based on Bell states, our protocol is more feasible in practice.
