This paper proposes a privacy-preserving platform to address the reluctance of small and medium-sized manufacturers to share their proprietary data with researchers due to competition and privacy concerns. Through this platform, manufacturers can share their data securely, and researchers can develop innovative tools that can solve real-world problems. The developed tools are then distributed back to the platform so that other manufacturers can use them while ensuring privacy and confidentiality. The utility of the platform is demonstrated through a case study of the development of an image analysis tool for quality control in mass production of food crystals. Instead of the conventional manual counting method, an automated crystal size distribution and counting tool, and a machine learning model for high-resolution translucent crystal and aggregate counting are developed, implemented as a web-based application, and securely distributed through the platform.
