Stable and secure image transmission based on temporal ghost imaging

The stability and security of communication is very important, and a ghost imaging mechanism is useful to transmit the object signal. In this paper, the image transmission based on temporal ghost imaging (TGI) is demonstrated. The image is encoded into a sequence of binary numbers which are considered as the temporal object. The influences of the realization times and the reference information are presented. The larger realization times lead to the higher resolution of the image, and the bit error rate drops to 0.63% with 300 measurements. The stability of the image transmission is analyzed, and the scheme presents a natural ability against the noise disturbance and the network congestion, which demonstrates that about 75% of the packet loss probability is permitted in the transmission process. The security has been discussed from four kinds of attack modes and the reference information, and the results indicate the secure technique. These properties confirm the potential applications in encryption and telecommunication with the advantages of high security and quality of reconstructed information.
