Callback Pattern for Decentralized Identifier Attestation Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional decentralized systems lack mechanisms for entities to verify the validity of attestations presented by others without knowing their identity, leading to potential interactions with invalid attestations.
Innovation Solution
Implementing a callback pattern for Decentralized Identifier (DID) attestations that includes contact metadata, allowing entities to contact the attestation provider directly for validation and verification, enabling negotiation of discounts or values without revealing the attestation owner's identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If entities use decentralized identifiers without a callback mechanism, then identity privacy is improved, but verification reliability deteriorates because entities cannot confirm attestation validity without knowing the owner's identity
Solution Approach 1:
The patent implements a feedback mechanism where the verifying entity sends a callback request to the attestation provider after receiving an attestation. The provider responds with verification information indicating whether the attestation is valid, creating a closed-loop feedback system that enables verification without revealing the owner's identity to the verifying entity.
Solution Approach 2:
The patent introduces an intermediary communication channel between the verifying entity and the attestation provider. The callback mechanism acts as this intermediary, allowing the verifying entity to query the provider about attestation validity through a controlled communication path that does not expose the owner's identity information.
2Reliability
If entities implement direct contact with attestation providers for verification, then verification capability is improved, but system complexity increases due to additional communication protocols and metadata handling
Solution Approach 1:
The patent segments the verification process into distinct components: the attestation itself, the contact metadata embedded in the attestation, and the separate callback verification step. This segmentation allows each component to have a specific function and keeps the overall system architecture modular and manageable.
Solution Approach 2:
The callback mechanism serves multiple functions: it verifies attestation validity, provides verification information to the requesting entity, and maintains the privacy of the attestation owner. This multi-functionality reduces the need for separate verification systems and simplifies the overall architecture.

AI summary
Embodiments disclosed herein are related to computing systems, computer program products, and methods for providing a callback pattern for DID attestations or claims. An attestation is provided from a first entity of a decentralized network to a second entity of the decentralized network. The attestation defines information about an owner of the attestation that has been generated by the first entity and that is to be used by the second entity. The attestation includes contact metadata that defines how to contact the first entity. In response to the attestation being provided to the second entity, the first entity is contacted using the contact metadata.
