Flashback: A Reversible Bilateral Run-Peeling Decomposition of Strings

Thomas Konstantinovsky, Gur Yaari · 2026

We introduce Flashback, a reversible string decomposition that repeatedly peels the maximal leading and trailing character runs from a sentinel-wrapped input, recording each pair as one bilateral toke…

Secure Conformance Checking using Token-based Replay and Homomorphic Encryption

Luis-Armando Rodriguez-Flores, Luciano Garcia-Banuelos, Abel Armas-Cervantes, Astrid-Monserrat Rivera-Partida · 2026

Conformance checking, one of the main process mining operations, aims to identify discrepancies between a process model and an event log. The model represents the expected behaviour, whereas the event…
