About
Evidence infrastructure for decisions that must be defended later.
Secoya Systems is building evidence infrastructure for regulated AI decisions that must remain independently verifiable over time.
Evidence must outlive the algorithm that signed it.
Long-lived records need explicit algorithms, key identifiers, renewal policy, and preserved lineage.
Trust is strongest at the moment of creation.
A record sealed beside the event is more defensible than a reconstruction assembled after a dispute.
Verification should cross infrastructure boundaries.
A verifier should be able to check the record without privileged access to the system that produced it.
Limitations are part of the evidence.
Identity, key custody, trusted time, completeness, and audit status must be stated — not implied by a valid signature.
