With Mantle Keeper, enterprises certify the integrity of data, systems, or devices instantly, securely, without any false positives, or exposing data to leaks.

Use cases

  • Background Checks: A system that uses zero-knowledge proof to validate if someone claims are authentic.
  • IoT Firmware Signature: A system that ensures that an IoT device firmware is authentic.
  • File Digital Authority: A system that ensures file authenticity (backup, research report, etc.) to avoid operating with tampered data or for compliance.

AND MORE!

You can find detailed use cases on Mantle Keeper in our Insights section.

Additional use cases are added on a weekly basis.

Concept

Keeper's goals are to protect by using blockchain technology your key files and to track files versioning. Whenever you add a file, its fingerprints will be stored on the blockchain across the network. Depending on the accuracy level provided, the file will be separated into a number of chunks to be stored on the blockchain. We do the same thing with a new version of a file. Whenever we compare a file to the file on the blockchain, we compare their fingerprints, and not the actual files.

Components

File

A file is a file that will be stored on the blockchain. A file is stored by creating a cryptographic representation of the file and store its fingerprint in the blockchain.

Version

A particular version of the file stored on the blockchain. For example, a document might have new requirements, so we can add a new version of that document in the blockchain. The original version will still be stored in the blockchain.

Folder

A folder is a way to group multiple files.

Accuracy Level

The accuracy level is how precise we create the cryptographic representation. The highest the accuracy level, the more chunks we'll create with that file. This means it will also take more time to process the file.
There are five accuracy levels:

  • Lowest
  • Low
  • Medium
  • High
  • Excellent
