Abstract:
[Problem] To provide a content generation device that can reduce the processing load of generating a hash value to be registered in a blockchain in a configuration that uses audio data in a video file. [Solution] An imaging device 102 generates a video file including video data, audio data, and metadata, and generates a hash value from the audio data and metadata. The imaging device 102 transmits the video file and the hash value to a management system 101, which registers the hash value and metadata on the blockchain.
