The invention provides an automatic desensitization processing method and system for sensitive information in a road traffic video, and the method comprises the steps: carrying out the extraction of obtained road traffic video frame data, and obtaining an extracted key video frame; text information in each key video frame is extracted, matching is carried out in a sensitive information base, and sensitive text information in the key video frames is obtained; sensitive character information in each key video frame is processed, and video frames arranged before and after the key video frame according to a time sequence are removed; and recombining the key video frames after sensitive character information processing and the remaining video frames which are not removed into a new desensitized video frame file. Compared with traditional video desensitization, traditional road traffic video sensitive information desensitization needs human interaction and needs to be filtered, screened and removed frame by frame, and manpower and time are consumed; through extraction of the video key frames, the processing number of the video frames is greatly reduced, and the processing speed is increased.

    本发明提供一种道路交通视频中敏感信息自动脱敏处理方法及系统,方法包括:对获取的道路交通视频帧数据进行抽取,获取抽取后的关键视频帧;提取每一张关键视频帧中的文字信息,在敏感信息库中进行匹配,得到关键视频帧中的敏感文字信息;对每一张关键视频帧中的敏感文字信息进行处理并将其按照时序排列的前后的视频帧剔除;将进行敏感文字信息处理后的关键视频帧以及剩余的未剔除的视频帧重新合并成新的已脱敏的视频帧文件。本发明与传统的视频脱敏相比,传统的道路交通视频敏感信息脱敏需要人工交互,需要一帧一帧的进行过滤筛选剔除,及其耗费人力时间;通过对视频关键帧的抽取,极大地降低了视频帧的处理数量加快了处理速度。
