Sign forensic evidence at every custody handoff
Can every acquisition, copy, analysis, export, and transfer be linked to an authorized actor and unchanged content?
Operational pain
Case tools record audit events but exports and inter-firm transfers can detach evidence hashes from identity, method, and custody context.
Trigger
Internal investigation, litigation hold, regulator production, or law-enforcement handoff.
QNSI contribution
Connect the decision to a controlled security path
Create QNSI-supported signature records for evidence digest, acquisition tool, operator, transformation, container, and recipient.
Decision artifact
A cryptographic custody envelope with ordered handoffs, method versions, signatures, and verification results.
What still requires validation
Investigators and counsel validate acquisition method, identity, storage, repeatability, admissibility, and privilege.
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.
