Seibu Construction and Partners Kickstart C2PA Technology Validation in Road Construction
In a significant advancement for the construction industry, Seibu Construction Co., along with partners Three Fields Co. and Cybertrust Co., has commenced validation of a video authenticity solution using the C2PA technology at a road construction site. This initiative responds to the rising concerns over video manipulation and impersonation stemming from the rapid evolution of AI-generated media and deepfake technology. The goal is to establish a strong trust framework, ensuring the authenticity of video evidence in construction projects.
Currently, the construction sector is increasingly utilizing stationary and wearable cameras for remote monitoring and quality control. Video recordings serve as crucial evidence, adhering to guidelines such as the 'Guidelines for the Use of Construction Record Videos.' However, with recent advancements in generative AI technology that make it easy to create hyper-realistic video content, distinguishing real footage from fake has become exceedingly challenging. This raises alarm over the longstanding assumption that 'video equals fact' in construction sites, leading to serious vulnerabilities regarding the credibility of visual data used for evidence.
C2PA, which stands for Coalition for Content Provenance and Authenticity, offers a standardized method to ensure video authenticity. By attaching signed metadata to video files specifying where, when, and by whom the footage was taken, third parties are enabled to objectively verify the authenticity of videos without being solely reliant on human judgment. This capability ensures that any tampering can be detected promptly, solidifying the transparency of projects to stakeholders and society at large.
Moving forward, the three companies plan to share insights gained from the validation experiment through publications and other means. Their ultimate aim is to support industries, particularly construction and infrastructure, in embracing digital transformation without concerns over authenticity. By establishing a reliable infrastructure, they hope to create a society where the benefits of digitalization can be safely enjoyed by all stakeholders involved in digital construction and beyond.

Background: The Need for Authenticity in Digital Construction
Currently, the construction sector is increasingly utilizing stationary and wearable cameras for remote monitoring and quality control. Video recordings serve as crucial evidence, adhering to guidelines such as the 'Guidelines for the Use of Construction Record Videos.' However, with recent advancements in generative AI technology that make it easy to create hyper-realistic video content, distinguishing real footage from fake has become exceedingly challenging. This raises alarm over the longstanding assumption that 'video equals fact' in construction sites, leading to serious vulnerabilities regarding the credibility of visual data used for evidence.
Addressing the Challenge
C2PA, which stands for Coalition for Content Provenance and Authenticity, offers a standardized method to ensure video authenticity. By attaching signed metadata to video files specifying where, when, and by whom the footage was taken, third parties are enabled to objectively verify the authenticity of videos without being solely reliant on human judgment. This capability ensures that any tampering can be detected promptly, solidifying the transparency of projects to stakeholders and society at large.
Roles of the Participating Companies
- - Seibu Construction: The construction firm is testing this solution on the Kitano-Shitamachi line project in Tokorozawa, where they are verifying the reliability of video evidence using C2PA technology. Their aim is to not only validate the technology but also to address practical challenges and assess the effectiveness of storing assured footage as new construction records.
- - Three Fields: They provide the video cloud service TStocker, incorporating C2PA technology for secure provenance data recording and signing across various camera feed streams. The vendor-neutral design facilitates easy adoption across diverse construction environments.
- - Cybertrust: They contribute by providing the 'iTrust C2PA certificate' that ensures provenance verification of TStocker's video data. As a certification authority, Cybertrust rigorously verifies the authenticity of signers, thereby reinforcing the trust model. Their commitment lies in promoting an open standard based on C2PA, fostering an interoperable ecosystem across the construction industry.
Future Prospects
Moving forward, the three companies plan to share insights gained from the validation experiment through publications and other means. Their ultimate aim is to support industries, particularly construction and infrastructure, in embracing digital transformation without concerns over authenticity. By establishing a reliable infrastructure, they hope to create a society where the benefits of digitalization can be safely enjoyed by all stakeholders involved in digital construction and beyond.
