Everyday online resources move, change, or disappear, making users rely on third-party repositories to keep the past available for them. The good reputation of these repositories makes them attractive targets for quiet tampering by attackers. This threatens trust in the authenticity of historical records, especially in an era of mechanized intelligence.
This talk will introduce Archive Transparency, a prototype that explores how transparency logs, Sigsum, and the witness network can solve this issue by establishing that a third-party repository content has remained unchanged over a long time. This talk will conclude with data from a small-scale deployment.
Speaker
Matthieu Daumas is a software engineer based in Berlin, Germany, with a background in compile-time cryptography and obfuscating compilers. Since 2024, he has been developing Archive Transparency, an open-source prototype exploring transparency logs for archival integrity. He is actively seeking collaborations and opportunities to help build resilient trust infrastructure for digital preservation.
