Using the quantum teleportation and quantum entanglement swapping, a quantum identification scheme of Cross-center based on W-state is proposed, and the identification for user in distributed network is realized. The scheme includes register phase and authentication phase, and the whole system consists of main server and client server. All the operations of any user are processed at client server and there is no direct communication between user and main server. All authentications are processed by servers based on the principles of quantum mechanics, and its security is guaranteed by quantum mechanism. Finally, the security of the quamtum identification scheme is analyzed.
