Keep clinical-trial signatures verifiable through the study lifecycle
Will consent, source-data, analysis, and submission signatures remain attributable and verifiable years after systems change?
Operational pain
Long-running trials cross vendors, countries, and platform migrations, while signature evidence can become inseparable from retired identity and timestamp services.
Trigger
A decentralized trial, e-signature platform replacement, or long-term archive design.
QNSI contribution
Connect the decision to a controlled security path
Inventory signature algorithms, signer identities, certificate chains, timestamps, and archive dependencies in QNSI.
Decision artifact
A trial-signature longevity register with revalidation checkpoints and evidence-preservation actions.
What still requires validation
Quality and regulatory teams confirm electronic-record requirements, identity proofing, timestamp trust, retention, and admissibility.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
