On April 20–21, 2026, the 4th International Workshop on Trends in Digital Identity (TDI 2026) takes place in Verona. The workshop program also includes the talk “Provenance Identity Continuity (PIC): Secure Authority Propagation from Human and Non-Human Origins Across Trust Boundaries”, presented by Nicola Gallo and Antonio Radesca (Nitro Agility Srl).
If you are interested in the topic of authority continuity across human and non-human origins and trust boundaries, you can find the event details and presentation materials here.
Presentation summary. This talk presents PIC (Provenance Identity Continuity), a model for secure authority propagation across distributed systems and AI agents. PIC shifts the primitive from authority-as-possession to authority-as-continuity: every execution step must be validated as a causal continuation of the same authorized lineage, with preserved origin and non-expanding authority.
