Three Fields and Cybertrust Collaborate on C2PA for Content Authenticity Assurance

Collaboration Announcement



Three Fields Co., Ltd. and Cybertrust Co., Ltd. have announced their partnership to develop a solution that guarantees the authenticity of video content utilizing the Coalition for Content Provenance and Authenticity (C2PA) technology. This collaboration is particularly timely as the market for AI-generated content continues to grow rapidly, raising concerns over content authenticity.

What is C2PA?


C2PA is an international industry coalition that establishes technical standards for verifying the provenance and authenticity of digital content. By initiating this partnership, the companies aim to create a ground-breaking solution that integrates their respective services: Three Fields' video cloud platform, TStocker, with Cybertrust's iTrust C2PA certificates. This solution is designed to record and store crucial provenance information—detailing when, where, and how content was filmed and edited—making it verifiable by third parties.

Enhancing Content Transparency


The rise of AI technology has significantly simplified the processes of creating and manipulating video content, contributing to serious societal issues such as copyright infringement and deep fakes. This situation is increasingly pressing for industries that rely on reliable video data, particularly in surveillance, inspections, and evidentiary documentation. Just as industries seek to ensure the integrity of these recordings, this partnership seeks to provide effective tools to guarantee content authenticity.

TStocker, offered by Three Fields, is a vendor-neutral platform that supports a wide range of camera manufacturers and services. It plays a vital role in the digital transformation (DX) across multiple sectors, including construction, infrastructure, and manufacturing. The videos gathered through these channels must meet high standards of reliability concerning operational integrity, safety, and legal admissibility. To enhance this reliability further, Three Fields and Cybertrust have committed to leveraging the C2PA technology as a next-generation de facto standard for digital content reliability.

Technical Collaboration Overview


The two companies plan to strengthen their collaboration in the following key areas:

Integration of Video Data and C2PA Technology


Utilizing Three Fields’ patented technology, both firms will ensure that the video streams and probe data recorded will have secure provenance information and electronic signatures. As a part of this initiative, they will develop capabilities for detecting tampering and tracking the history of video data stored in TStocker.

Strengthening Reliability Through Authentication


The collaboration will employ Cybertrust's authentication technologies and iTrust C2PA certificates to create a robust certification framework guaranteeing video data authenticity through TStocker. This includes promoting the use of timestamping and electronic signature technologies to ensure the credibility of electronic evidence.

Future Prospects


Through this collaboration, Three Fields and Cybertrust aspire to establish a de facto standard for guaranteeing the authenticity of digital video in the industrial sector. Their goal is to facilitate a secure environment where users can confidently utilize visual data in the age of AI while accelerating digital transformation.

To validate their technologies, Three Fields plans to conduct practical experiments using signed video data from its partner companies, employing C2PA technology. The aim is to demonstrate the effectiveness of the solutions they've developed and swiftly integrate the findings into service offerings, ensuring a timely market launch of reliable video solutions.
