and how the blockchain protects digital assets
An Attestiv fingerprint is a unique identifier that is calculated using the bits from either a file or a data stream. When we create a fingerprint of a digital asset like a photo, video, document or piece of data, we then put the fingerprint in a blockchain. The original asset, like a photo, associated with the fingerprint is not stored with the fingerprint on the blockchain.
Why Blockchain?
The goal of blockchain is to allow digital information to be recorded and distributed, but not edited.
What is Blockchain?
A blockchain is a growing list of records, called blocks, that are linked together using cryptography. Each block contains:
- a cryptographic hash of the previous block
- a timestamp
- transaction data
The timestamp proves that the transaction data existed when the block was published to get into its hash. As blocks each contain information about the block previous to it, they form a chain, with each additional block reinforcing the ones before it.¹
The benefit of Blockchain storage
Once blockchain information is recorded, the data in any given block cannot be altered retroactively without altering all of the following blocks in the chain. In this way, a blockchain is the foundation for immutable ledgers, or records of transactions that cannot be altered, deleted, or destroyed.
At Attestiv, we are able to secure data by fingerprinting each item to the blockchain to prevent potential inside and outside threats.²

Understanding the Fingerprint Status
Authentic
The green checkmark indicates that the item, like a photo, was fingerprinted at the time of capture. This can take place when a customer takes a photo through an app that has been connected to Attestiv via API or through an Attestiv mobile workflow. Through this method, we are able to gather and confirm the details associated with the item like time, date and location.
Imported
The yellow checkmark tells us that this item has been imported into the Attestiv system versus being fingerprinted at the time of capture (which results in the green checkmark).
Altered
The red X denotes an unvalidated, not fingerprinted or unauthentic image or other digital media item. Items with red x’s should be rejected completely and/or investigated internally to ensure they are safe for use.
Summary
Using blockchain as a system of record for fingerprinting media at the point of capture or after AI-based forensic analysis, Attestiv offers a foundational platform for any organization reliant on digital photos, videos and documents.
Attestiv helps industries such as insurance accelerate digital transformation, reducing the threat of fraud from deepfakes and media alterations. Furthermore, Attestiv fills a growing need for self-service and remote operations.
