Purposes--To design a new and secret quantum blind signature scheme. Methods--A five-qubit Cluster state functions is used as quantum channel to link signature system participants. Based on quantum teleportation, these participants complete blind message, signature and verification via performing the particles held by themselves. Results--Through security analysis, a feasible and secure quantum blind signature scheme is obtained. Conclusion--Signature scheme obtained with this method can be applied to some fields such as e-payment and e-voting, so it has a practical significance.
