Notarization Process

Blockchain verification in 4 steps

1

Digital Fingerprint Generation

A unique SHA-256 hash of the file or data is calculated. This cryptographic fingerprint uniquely identifies the content without revealing it.

2

Blockchain Registration

The hash is grouped into a Merkle tree and anchored to the Ethereum blockchain, creating an immutable record with a verifiable timestamp.

3

Certificate Issuance

A notarization certificate is generated with the hash, blockchain transaction, timestamp, and a public verification URL.

4

Independent Verification

Anyone can verify document authenticity by comparing its hash with the blockchain record, without relying on third parties.

Digital Authentication

Immutable Notarization

Ensure file authenticity and integrity with verifiable and immutable blockchain notarization.

1

Blockchain Notarization

Record file hashes on Ethereum public blockchain to create immutable and verifiable evidence of existence and timestamp.

2

Instant Verification

Verify file authenticity and integrity instantly by querying blockchain records without intermediaries.

3

Electronic Signatures

Sign documents digitally with blockchain validation, meeting legal standards and ensuring non-repudiation.

Chain of Custody

Establish verifiable chain of custody for documents with immutable record of creation, modifications, and access.

Verifiable Certificates

Generate authenticity certificates with QR codes and public blockchain verification URLs.

API Integration

Integrate notarization into existing workflows via REST API to automate authentication processes.

Irrefutable Proof

Data integrity guaranteed by blockchain

Acronis Notary Cloud provides cryptographic evidence that a file existed at a specific time and has not been altered since.

Verification Methods

Available verification technologies

Notary Cloud

SHA-256 Cryptographic Hash

Each file produces a unique 256-bit digital fingerprint. Any modification, however small, generates a completely different hash.

Digital Certificate

Verifiable PDF document containing the hash, blockchain transaction, file metadata, and a QR code for quick validation.

Certified Timestamp

RFC 3161 timestamp anchored to the blockchain block, providing cryptographic proof of the exact moment of notarization.

Chain of Custody

Complete record of every notarization, access, and verification of the file, creating an auditable digital chain of custody.
