A Data Encryption and Fast Transmission Algorithm Based on Surveillance Video

الملخص EN

Video surveillance is an effective way to record current events.

In view of the difficulty of efficient transmission of massive surveillance video and the risk of leakage in the transmission process, a new data encryption and fast transmission algorithm is proposed in this paper.

From the perspective of events, the constraints of time and space dimension is broken.

First, a background and moving object extraction model is built based on video composition.

Then, a strong correlation data encryption and fast transmission model is constructed to achieve efficient data compression.

Finally, a data mapping mechanism is established to realize the decoding of surveillance video.

Our experimental results show that the compression ratio of the proposed algorithm is more than 60% under the premise of image confidentiality.
