SSI Transaction Agents for Private Credential Verification Monetization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-sovereign identity (SSI) infrastructure models lack effective mechanisms for securely processing transactions, tracking, and monetizing the use of verifiable credentials while maintaining privacy and security.
Innovation Solution
Introduce transaction agent roles (issuer, holder, and verifier) to track and monetize transactions within the SSI infrastructure without altering core infrastructure requirements, enabling cryptographic and policy-based verification and payment schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional SSI infrastructure is used with direct issuer involvement in transactions, then credential verification can be performed, but system complexity and transaction processing time increase
Solution Approach 1:
The patent extracts the issuer from the transaction verification process. Instead of requiring the issuer to be directly involved in each transaction, the system uses cryptographic proofs (verifiable presentations) that allow holders to prove credential validity independently. The issuer only needs to sign the credential initially, not participate in subsequent transactions involving that credential.
Solution Approach 2:
The patent introduces transaction agents as intermediaries that facilitate verification without requiring direct issuer involvement. These agents use cryptographic protocols to verify proofs and facilitate transactions, acting as mediators between holders and verifiers while maintaining security without adding issuer complexity to the transaction flow.
2Loss of information
If verifiable credentials are made publicly accessible for verification, then transparency is improved, but privacy protection deteriorates
Solution Approach 1:
The patent applies local quality by allowing selective disclosure of credential data. Holders can create verifiable presentations that include only specific data points from credentials rather than the entire credential content. This enables transparency for the specific information needed while maintaining privacy for other data points that don't need to be disclosed.
Solution Approach 2:
The patent uses cryptographic copying where verifiable presentations are created as proofs that reference credential data without exposing the original credential content. These presentations can be shared and verified publicly while the actual credential data remains private and stored securely in the holder's wallet.
3Device complexity
If SSI infrastructure operates without monetization mechanisms, then simplicity is maintained, but economic sustainability deteriorates
Solution Approach 1:
The patent implements self-service monetization where transaction agents automatically execute payment and reimbursement logic based on pre-configured policies. The system autonomously handles economic transactions including charging verifiers for verification services and reimbursing holders for credential usage, without requiring complex manual billing infrastructure or centralized control.
Solution Approach 2:
The patent uses preliminary action by establishing payment policies and economic rules in advance before transactions occur. These pre-configured policies automatically execute during transactions, enabling monetization without adding complexity to the transaction flow. The economic framework is set up beforehand and then self-executes based on transaction conditions.

AI summary
Systems and methods for transacting over a network. A first agent and a second agent are provided. The second agent is operable to transact with a third agent for use of a service, the third agent enabled to communicate with a fourth agent. The first agent is operable to communicate with the second agent to facilitate the transacting by the second agent with the third agent for the use of the service. The first agent is further operable to communicate with the fourth agent to facilitate the transacting by the second agent with the third agent for the use of the service.
