Video surveillance is an effective way to record current events. In view of the difficulty of efficient transmission of massive\nsurveillance video and the risk of leakage in the transmission process, a new data encryption and fast transmission algorithm is\nproposed in this paper. From the perspective of events, the constraints of time and space dimension is broken. First, a\nbackground and moving object extraction model is built based on video composition. Then, a strong correlation data encryption\nand fast transmission model is constructed to achieve efficient data compression. Finally, a data mapping mechanism is\nestablished to realize the decoding of surveillance video. Our experimental results show that the compression ratio of the\nproposed algorithm is more than 60% under the premise of image confidentiality.
