JLINC is an open protocol for controlling data use on the Internet –- after it is shared. The session focused on an Alice and Bob Co volunteered personal data use-case.



JLINC is an open protocol for controlling data exchange across the internet. It combines several strands of recently evolved technology to create a fully decentralized solution for Internet “data provenance” – a signed, private chain-of-custody to control data, after it is shared.

Human and machine-readable Information Sharing Agreements (ISAs) written in the universal web language JSON, are signed using industry standard curve25519 public key cryptography.

A compact digital fingerprint of the signed agreement, called a “hash,” is recorded on a distributed global ledger (blockchain).

This provides a “digital return receipt” and an audit trail, which allows all parties to prove that the signed copy of the agreement they each hold covers their data, and that it was signed by the opposite party when it was recorded on the ledger.
