STRINGS Evidentiary Custody Platform
Regulatory Evidence that's Beyond Reproach and Works in any Industry

ZKIAM™ — zero-knowledge identity and access, under every module.
ZKIAM™ is the zero-knowledge identity and access engine the STRINGS system runs on.
STRINGS does not replace your applications or your cloud. It sits underneath them as the layer where custody, lineage, and proof are enforced by architecture rather than policy.
Access to a sealed record is machine-to-machine and cryptographically proven — without exposing the record to prove it. No standing privileges, no shared credentials, no human path to the underlying data. Every access decision becomes part of the evidence rather than a gap in it.
No standing privileges
Access is granted per request, per record, and expires with it.
Machine-to-machine only
No shared credentials and no human path to the underlying data.
Proof without exposure
Authorisation is verified cryptographically, never by revealing the record.
Access is evidence
Every decision is sealed into the same immutable chain as the record.
STRINGS — the platform behind EpositBox
One immutable engine. Seven modules.
Each module answers a question someone will eventually ask under pressure. Together they form a continuous chain of custody, not a collection of tools.
Seal
Cryptographic point-of-capture
Fixes a record the moment it exists — content, time, and origin bound into a single verifiable seal that cannot be re-cut.
“Can you prove this is the original?”
Archive
Retention that outlives systems
Immutable long-horizon storage with versioning and indexed retrieval, governed independently of the applications that created the data.
“Will it still be there — and intact — in ten years?”
Exchange
Custody that survives handoff
Move records between parties without surrendering proof. Recipients verify authenticity independently, without trusting the sender.
“Did anything change between us?”
Trace
Every touch, permanently recorded
Deterministic lineage across reads, writes, transfers, and deletions — a chain of custody assembled continuously, not reconstructed later.
“Who touched this, and when?”
Attest
Evidence on demand
Generate independently verifiable proof packs for auditors, regulators, and counterparties — without exposing the underlying data.
“Show me, don't tell me.”
Respond
Defensible under pressure
Incident, breach, and litigation workflows that draw on sealed history — so response timelines are reconstructed from evidence, not memory.
“What exactly happened, and when did you know?”
Journal
The permanent record
An append-only ledger of decisions and system events, forming a high-integrity corpus for supervisory review and AI oversight.
“What was the basis for this decision?”
Packaging
Modules compose into industry suites.
Configured, not customised. Same engine, same proof model — different configuration for each sector's obligations.
Financial Services
Banks, insurers, and capital-markets firms operate under continuous examination. STRINGS turns records, decisions, and recovery points into evidence a supervisor can verify independently.

Why it holds up
Three properties every piece of evidence needs.
Point-in-time
A record is sealed at the moment of capture — content, time, and origin bound together. Nothing is fixed retroactively, because retroactive is exactly what a challenger will attack.
Independently verifiable
Verification does not require trusting EpositBox, your vendor, or your own systems. The proof stands on its own, checkable by a third party.
Permanent
Evidence has to outlive the platform that produced it. STRINGS is built for retention horizons measured in decades, with cryptographic agility as standards move.
