| Abstract: | This paper introduces a scheme based on coincidence measurement to realize optical information protection between two communicators.The sender chooses appropriate carrier signals to attach important information to the object in the test arm.The receiver retrieves the information from the coincidence measurement according to an agreement between the sender and the receiver.The results of numerical computing show that our scheme can protect the information successfully and has a good performance on secrecy. |
