- Abstract
- With an increased interest in personal information protection, there are numerous efforts to reduce personal information leakage caused by existing video surveillance services that continuously monitor and analyze multiple video streams at a surveillance control center. In particular, the face images included in the video stream are the most vulnerable information to easily identify specific personal information. In this paper, we propose a real-time face de-identification system that finds the locations of faces through a face detection deep learning model and modifies the corresponding pixels to make the faces unrecognizable. In order to accelerate the overall process, we apply TVM-based deep learning inference optimization and task-level pipeline parallelism to the proposed face de-identification system. Throughout experimental results, we show the effectiveness of the proposed system for providing face de-identification service in real-time.
