How It Works
How Audrie Works
Audrie is a two-sided platform. On one side, identity-verified individuals and organisations authenticate documents – creating a permanent, tamper-evident record. On the other, any receiver of an authenticated file can verify it in seconds, for free.
Every authentication is cryptographically bound to a verified identity. Every verification returns a definitive result.
For Authenticators
Prove your documents are genuine.
When you authenticate a document through Audrie, you create a verifiable record that cannot be denied, altered, or forged. Anyone who receives your document can check it against the Audrie register instantly.
Step 1
Verify Your Identity
Before you can authenticate documents, Audrie confirms who you are. This is a one-time process.
Identity verification is conducted through a government-grade identity verification provider. The process includes:
- Government document verification (passport, driver's licence)
- Liveness testing to confirm you are a real person
- Biometric capture for future authentication challenges
For company directors and employees, Audrie also checks relevant role or registration information against government registers, such as ASIC in Australia. This does not determine legal authority to bind another party, capacity or freedom from duress.
For accountants and lawyers, your professional standing is confirmed against your professional body's register (CPA Australia, Law Society, and equivalent). This extra step enables registered professionals to access the higher standard ‘Independent Authentication’ standard.
Enterprise clients (e.g. ASX 200 and equivalent private companies) complete an additional in-person verification with the Audrie team. This establishes the highest level of chain-of-trust assurance.
Step 2
Authenticate Your Document
Log in to app.audrie.io using your passkey. Your device prompts a biometric challenge – fingerprint, face ID, or equivalent – every time you log in.
Select the document you want to authenticate. Your browser processes its contents locally. Audrie accepts any file type up to 100MB.
Review the document, then tap “Issue Authentication.” A second biometric passkey challenge is triggered.
Upon confirmation, Audrie:
- Receives the hash computed locally by your browser, together with your single-use passkey authorisation and optional metadata
- Signs the canonical payload using your encrypted ML-DSA-65 key, decrypted through AWS KMS only for the authorised operation and then cleared from memory
- Records the signature, signatory identity and timestamp, and publishes the signed payload to Hedera HCS
Your document’s contents stay on your device. Audrie retains the hash, signature and authentication metadata, including signatory identity and timestamp, rather than the document itself.
Step 3
Share Your Document
The authenticated PDF itself carries the proof when you choose the embedded certificate option. Your browser appends the certificate page as an incremental update, preserving the original content. It hashes the assembled PDF with the reserved signature field zeroed, then inserts the signature returned by Audrie. This optional authentication page is distinct from a verification certificate documenting a later check.
The authenticated filename is prefixed with “A-” to indicate authentication (for example, A-Results_Announcement_Q3_2025.pdf).
Recipients can verify the document through the Audrie verification endpoint at any time, for free.
For Verifiers
Check any document in seconds.
If you have received a document and want to confirm it is genuine and unaltered, verification takes less than a minute.
Step 1
Go to the Verification Endpoint
Navigate to app.audrie.io/public/verify. No account required. Enter your email address and complete a CAPTCHA. That's it. Returning verifiers are recognised automatically via cookie, reducing friction for repeat checks.
Step 2
Upload the Document
Upload the document exactly as you received it. Do not alter any of the contents (eg. adding a signature) as any modification will change the cryptographic hash and will affect the verification result.
Step 3
Receive Your Result
Audrie returns a result in under one second. The result includes:
- Match status: whether the document hash matches a record in the Audrie database confirming that the document hasn't been modified since being authenticated
- Authenticator identity: the name, role, and organisation of the person who authenticated the document
- Authentication date: the precise timestamp of authentication
- Authenticator current status: whether the authenticator remains active or has been revoked
- Onboarding tier: whether the authenticator completed Enterprise Verified or Standard onboarding
Step 4
Download Your Verification Certificate
Web verification is free and does not require an account. To download a Verification Certificate that proves you checked the document, when you checked it, and what result you received, sign in or create a free account. The certificate is free too.
The Verification Certificate is itself system-authenticated by Audrie. It's a tamper-evident record of your due diligence.
This certificate records your check. Its evidentiary use depends on the applicable rules and the circumstances of the proceeding. Read the expert legal opinion for the assessment and its qualifications.
Trust Tiers
Not all authentication is equal.
Audrie supports two types of authentication. They reflect different levels of trust and different use cases.
Type 1
Self-Authenticated
A company director or authorised employee authenticates a document on behalf of their organisation. The authenticator is identity-verified and relevant role or registration information is checked against the government register. Legal authority to bind the organisation remains a separate question.
This is the standard authentication type for corporate documents: financial statements, company disclosures, contracts, and correspondence.
Type 2
Independently Authenticated
A qualified professional – an accountant or lawyer – authenticates a document on behalf of a client. The professional's identity is verified and their professional standing is confirmed against their professional body's register.
Independent authentication provides a higher trust tier. The professional warrants to the authenticity of the document, adding their professional accountability to the authentication record. This type is appropriate for documents where a professional opinion or sign-off adds evidential weight: audited accounts, legal documents, trust deeds, and regulatory submissions.
Verification Levels
Enterprise Verified
Initial authenticators are verified in person by a member of the Audrie team, followed by the standard remote IDV process. This establishes the highest level of chain-of-trust assurance and prevents remote impersonation of a corporation's identity. Enterprise Verified status is displayed on all verification results for documents authenticated by enterprise clients. Only Enterprise Verified businesses are permitted to create automated system-issued authenticated documents.
Standard
Remote identity verification plus register checks. Available for all self-authenticated and independently authenticated users.
