Aiming at pure three-qubit states and the measure of entanglement,this paper proposed pure W-like state.Based on pure W-like state,this paper proposed a strong blind quantum signature protocol.The protocol adopted the quantum key distribution,the quantum fingerprint and one-time pad.The protocol ensures that the signature is blind and the message owner is untraceable.Moreover,the protocol provides the unconditionally security,lower complexity and best quantum bit efficiency.This protocol is a novel method for constructing the strong blind quantum signature protocol.
