EU AI Act · GDPR · Signed, timestamped & anchored · Human-in-the-loop

The EU AI Act is now mandatory.
Are you ready?

The EU AI Act is now in force. Can you prove how you used AI in your documents? Companies that fail to document, trace, and audit their AI processes face fines of up to €15M or 3% of global turnover. Needine seals verifiable evidence of what your AI does and helps you document your compliance.

"Guaranteed document integrity, auditability, and traceability."
Reviewable by any person or organization.

Regulators, auditors, and clients want to know which model, which version, which data, who reviewed it, and who approved it — before they trust any AI-assisted decision. Needine makes all of that provable.

How it works

Your company uses AI to produce sensitive documents. Needine gives you verifiable proof of integrity, traceability, and human control.

The structure never changes. Only the data does — and that's where AI delivers maximum value.

01

Human input & evidence

The team gathers context, source data, and supporting documents. Each file is hashed locally: only its SHA-256 fingerprint is attached to the record, never the file.

02

Data integrity validation

The record (hashes, model, version, steps and context) is canonicalized and hashed. Nothing can be silently altered after this point.

03

AI drafts — human decides

Your AI generates the draft, and the record says which model and version produced it. The model proposes; a person approves.

04

Multi-step approval chain

Reviewer → Approver → Signatory. Each action is timestamped and hashed. The full chain becomes part of the cryptographic proof.

05

Signed, timestamped and anchored

The approved record is signed with Ed25519, gets an RFC 3161 timestamp within the hour, and is anchored on Arbitrum One via a Merkle tree. Anyone can verify it without logging in.

Platform capabilities

Built for regulated, high-stakes document operations

🔐

Cryptographic signatures

Every document is signed with Ed25519 and includes a canonical hash. Tampering is mathematically detectable — not just logged.

⛓️

Timestamp and blockchain anchor

Each certificate gets an RFC 3161 timestamp within the hour, and the Merkle root that includes it is anchored on Arbitrum One. The on-chain record is permanent and independent of Needine.

👥

Auditable approval workflow

Reviewer, approver, and signatory roles with delegation support. The entire approval chain is embedded inside the signed payload.

📊

AI trust scoring

Each certificate receives a 0–100 trust score from 8 fixed checks: valid signature, confirmed anchor, provenance chain, complete metadata, identified model, and more.
