Construction photo-editing has prevailed among the Japanese construction industries as digitalization of photography becomes popular. Some of these “photo-editing” are made on as-needed basis in construction management process, while some are found to be the forgery of construction record. In this paper, categorization of “photo-editing” methods are firstly made based on the case survey in construction industries. Secondly, technical requirements of construction photo-editing detection method is summarized with particular consideration for editing needs in construction management processes. Thirdly, we have proposed a newly developed photo-editing detection method called “ROI expected-noise method”, and examined the performance using simulated samples of edited construction photography. The method has shown high detection performance and fulfilled the above mentioned requirements.
