medicalinformatics/SecureEpilinker

SecureEpilinker (MainSEL) is an academic-grade implementation of privacy-preserving record linkage. While it addresses a high-complexity domain (medical informatics and SMPC), it suffers from extreme stagnation, with no updates in over six years and negligible community adoption (11 stars). The technical moat is thin because the project is essentially a wrapper around the ABY library for a specific use case. In the modern landscape, this tool faces heavy displacement from 'Data Clean Room' solutions offered by cloud giants (AWS Entity Resolution, Snowflake Data Clean Rooms) and more active open-source privacy frameworks like OpenMined's PySyft or dedicated PPRL libraries like 'anonlink'. The niche nature of German medical informatics standards (Mainzelliste) provides a slight buffer against frontier labs like OpenAI, but the underlying technology is being superseded by more performant and easier-to-integrate SMPC and Homomorphic Encryption (HE) protocols. It serves more as a historical reference for how PPRL was implemented in the mid-2010s than a viable production tool for today's market.
