graduated disclosure

Definition

Lifting confidentiality step by step: Selectively disclosing more data as time and/or necessity progresses, offering backwards verifiability of earlier issued cryptographic proofs.

Example

You proof your insurance policy without disclosing details, before enjoying extreme sports. Only when something goes wrong, e.g. 1 in a 100, you disclose the data. This way confidentiality is kept in 99% of the cases.

KERI specific

Disclosure performed by a presentation exchange that has cross-variant (see compact variant) Issuer commitment verifiability as an essential property. It supports graduated disclosure by the Disclosee of any or all variants wether it be full, compact, metadata, partial, selective, bulk issued, or contractually protected.

Reuse

The SAID of a given variant is useful even when it is not the SAID of the variant the Issuer signed because during graduated disclosure the Discloser MAY choose to sign that given variant to fulfil a given step in an IPEX graduated disclosure transaction.

Rule

The disclosure performed by a presentation exchange MAY be graduated and MAY be contractually protected.
