Kingfisher Distributed Spectral Signature Database

A peer to peer spectral database designed for the RamanPi open source spectrometer.

Specifications (Work in progress)

The master ledger ??

Trust score changes

Calibration scores

Identity

An identity is a set of public and private keys.

• Creating an identity should require a proof of work
• Public identity should be derived from the private key and verifiable via public key
• Every contributions of an identity should be signed using the private key and verifiable via the public identity

Attributes

• Public key
  • Public Idenfier
  • Used to verify ownership of contributions
• Private key
  • Secret key that only the client holding the identity knows
• Calibration score
  • Head of calibration attempts in the ledger?
• Trust score
  • Sum or trust level changes in the ledger?
• Contributions list
  • List of all the contributions from the ledger?

Contributions

A contribution to the database.

Spectral Signature (Contribution)

A new signature, wether it is identified or not.

Spectral Signature Review (Contribution)

A signature for an existing signature, wether it is identified or not.

Spectral Signature Identification (Contribution)

An identification of a signature, wether it is identified or not.

Confidence Level

There are several ways to assign trusts to an identity, we could use a peer review system where a machine could be assigned a trust value. Or we could assign a confidence value in a signature, so if the signature was only matched once, it would come up in search results but have a low base confidence score (perhaps boosted if the associated identity has a high trust score). And if this signature is validated by different identities it would see its score improve every time. Once it reaches a certain thresholds it could get permanently committed to the database (perhaps we could have archive nodes who maintain a copy of every signature above a certain threshold).
