Data & Time Integrity Record
Every file we process is secured by generating a SHA-256 digital fingerprint of both its content and its metadata. These fingerprints are then anchored and timestamped on an immutable blockchain, creating a permanent, verifiable proof of authenticity.
Our approach ensures that data cannot be altered without detection, safeguarding information integrity and making it fully audit-ready. By combining cryptographic precision with blockchain immutability, DigitalWitness delivers trust, transparency, and compliance at every step of the digital record lifecycle.
How it works
1. Data Collection
-
Every process begins with the secure intake of digital files. Whether they are images, documents, or structured records, the files are preserved in their original state.
-
This guarantees that what enters our system remains unchanged, forming the foundation for reliable verification.
2. SHA-256 Fingerprint Creation
-
Immediately upon collection, each file undergoes cryptographic processing.
-
We generate a SHA-256 hash—a unique 64-character digital fingerprint derived from the file’s binary data.
-
Even the slightest alteration in the file would produce a completely different fingerprint, making this step the core of integrity assurance.
3. Blockchain Timestamping
-
Both fingerprints are then anchored into an immutable blockchain.
-
This process assigns an incorruptible timestamp that proves the file and its metadata existed in a specific state at a specific moment in time.
-
The blockchain’s distributed nature prevents tampering, creating a public and permanent record of authenticity.
4. Metadata & EXIF Extraction
-
Files are more than their visible content; they also contain metadata.
-
This includes details such as creation date, modification history, camera information, or geolocation tags in the case of images.
-
By extracting and analyzing this metadata, we capture the hidden context that is essential for full traceability.
5. Database Production of Date, Time and Metadata
-
Everything has been processed through SHA-256. and now structured into a database.
-
This creates a separate, immutable fingerprint for the contextual information.
-
Together, the file hash and the metadata hash ensure both what the file is and the story it tells remain verifiable.
6. Integrity Reports & Verification
-
Finally, we generate comprehensive integrity reports. These reports combine the original file, its hashes, and the blockchain record into a verifiable package.
-
Organizations and auditors can independently confirm authenticity at any time, ensuring data is always ready for compliance reviews, forensic investigations, or legal defense.
