| dc.description.abstract | Nowadays, the explosion of CCTV cameras has resulted in an increasing demand for distributed solutions to efficiently process the vast volume of video data. However, the use of surveillance, where people are being watched remotely and recorded continuously, has raised a significant threat to visual privacy. Existing systems often cannot prevent any party from exploiting unwanted personal data of others. In this paper, we develop an intelligent surveillance system with integrated privacy protection, built on big data tools such as Kafka and Spark Streaming. To protect individual privacy, we propose a privacy-preserving solution based on effective face recognition and tracking mechanisms. Specifically, we associate body pose with facial recognition to reduce privacy leaks across video frames. Additionally, body pose is exploited to infer person-centric information like human activities. Extensive experiments conducted on benchmark datasets further demonstrate the efficiency of our system for various vision tasks. | en_US |
