SSI Transaction Agents for Privacy-Preserving Tracking and Monetization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-sovereign identity (SSI) infrastructure models face challenges in securely processing transactions, tracking, and monetizing the use of SSI infrastructure and services, while maintaining privacy and enhancing system security and usability.
Innovation Solution
The introduction of transaction agent roles (issuer, holder, and verifier transaction agents) within the SSI system enables secure transaction processing, tracking, and monetization without altering core SSI infrastructure, using cryptographically verifiable credentials and policy enforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional SSI infrastructure is used for transaction processing, then decentralization and privacy control are maintained, but secure transaction processing and tracking capability are insufficient
Solution Approach 1:
The patent introduces transaction agents as intermediary components that mediate between the decentralized SSI infrastructure and the transaction processing requirements. These agents verify credentials, enforce policies, and track transactions without centralizing control, thus improving security while maintaining the decentralized architecture's simplicity.
Solution Approach 2:
The system segments transaction processing into distinct functional components: credential verification, policy enforcement, and transaction tracking. Each transaction agent handles specific tasks independently, allowing the system to achieve comprehensive security through modular, manageable units rather than a monolithic complex system.
2Reliability
If transaction tracking and monetization are implemented in SSI system, then system security and usability are enhanced, but privacy protection may be compromised
Solution Approach 1:
Transaction agents serve as privacy-preserving intermediaries that enable tracking and monetization without exposing sensitive personal information. They verify credentials and enforce policies using cryptographic proofs and zero-knowledge techniques, allowing the system to monitor transactions for security and billing purposes while keeping individual user data confidential.
Solution Approach 2:
The system applies different levels of information disclosure to different parts of the transaction process. Sensitive personal information remains protected locally within user devices, while only necessary verification data is shared with transaction agents for tracking and monetization purposes, thus maintaining privacy while enabling system-wide security and usability enhancements.
3Reliability
If multiple transaction agents are introduced for credential verification, then transaction security is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary credential verification and policy validation through transaction agents before final transaction execution. By pre-verifying credentials and establishing trust relationships in advance, the system reduces the time required for actual transaction processing while maintaining enhanced security through multiple verification layers.
Solution Approach 2:
The patent combines multiple verification functions into integrated transaction agents that perform credential verification, policy enforcement, and transaction tracking simultaneously. This merging of functions reduces the overall processing time compared to sequential verification by separate components, while still maintaining the security benefits of multiple verification steps.

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 network-enabled service based on a first transaction policy from a fourth agent, the third agent enabled to communicate with a fifth 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 network-enabled service based on the first transaction policy and communicate with the fifth agent to facilitate the transacting by the second agent with the third agent for the use of the network-enabled service.
