Abstract: A digital evidence management system 1 is configured to comprise a storage device that stores log data of a device operated in a predetermined process and video data obtained by shooting the process, and a computing device that executes a processing of specifying sectional video data for a time frame where the log data exists out of the video data, a processing of applying a predetermined data reduction processing to the sectional video data, and a processing of storing the video data subjected to the data reduction processing for the sectional video data in the storage device as digital evidence for the process.
