Implementer informative
A 2026 paper by Daniel Hardman analyzing entviz, an algorithm that renders a high-entropy value such as a key fingerprint as layered perceptual channels so an untrained person can tell whether two values match. It sets out a channel-by-channel perceptual-entropy budget, distinguishes human-centric authentication visualization from machine perceptual hashing, and proposes a commit-and-reveal comparison walk, noting that the budget is an analytic estimate. It is for designers of key and identifier verification.
