Blockchain Credential Verification via Smart Contracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of proving identity and credentials is cumbersome and costly for various industries, often resulting in inaccurate and incomplete verifications due to variability in verifier reliability and changes in credential status over time.
Innovation Solution
A method for recurring credential presentation is introduced, where a subscriber requests a credential subscription from a holder, which is consented to and recorded, allowing automatic presentation of credentials based on predefined conditions without additional holder consent, utilizing a blockchain-based system for secure and tamper-evident storage and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual credential verification is performed by third parties, then verification can be conducted, but the process becomes cumbersome and costly with variable reliability
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a trusted mediator between credential holders and verifiers. The blockchain network provides a decentralized, tamper-proof ledger that automatically verifies credential authenticity and status, eliminating the need for multiple manual verification steps while ensuring consistent reliability across all verifications.
Solution Approach 2:
The patent replaces manual, human-based verification processes with automated cryptographic verification mechanisms. Digital credentials use cryptographic signatures and blockchain consensus algorithms to automatically verify authenticity, replacing the mechanical process of manual document checking and human judgment with deterministic computational verification.
2Productivity
If credentials are verified manually, then verification can be performed, but valuable time is wasted in the process
Solution Approach 1:
The patent implements preliminary action by having credentials verified and recorded on the blockchain at the moment of issuance or renewal. The credential status is proactively updated and stored immutably on the blockchain before any verification request occurs, allowing instant verification later without requiring time-consuming manual checks or follow-up validation.
Solution Approach 2:
The patent replaces time-consuming manual verification with instantaneous cryptographic verification. The blockchain network and smart contracts enable automated, real-time verification of credential authenticity and current status, reducing verification time from days or hours to seconds while increasing productivity.
3Reliability
If traditional verification methods are used, then credentials can be checked, but costs are high due to manual processes
Solution Approach 1:
The patent replaces expensive manual verification operations with low-cost automated cryptographic verification. Blockchain network nodes collectively perform verification through consensus mechanisms, distributing the computational workload and eliminating the need for paid manual reviewers while maintaining high reliability through cryptographic proof and immutability.
Solution Approach 2:
The patent enables self-service verification where credential holders can independently prove their credentials' authenticity and current status through blockchain-based cryptographic proofs. The system allows holders to autonomously demonstrate credential validity without requiring external verification services, reducing costs while maintaining reliability through mathematical proof.
4Loss of information
If static verification is performed, then initial credential status is captured, but changes in credential status over time are not detected
Solution Approach 1:
The patent implements continuous verification through blockchain-based credential records that are actively updated and maintained on the distributed ledger. The system continuously monitors and records credential status changes (such as revocation, expiration, or renewal) on the blockchain, ensuring that verification information remains current and accurate without requiring periodic re-verification campaigns.
Solution Approach 2:
The patent incorporates feedback mechanisms where the blockchain network and smart contracts automatically notify relevant parties of credential status changes. When a credential status changes, the system provides feedback through blockchain transactions and smart contract events, ensuring that all verifiers receive real-time updates about credential validity without requiring complex manual monitoring systems.
Data Source
AI summary
Systems and methods which provide the ability for users to track the lifecycle and conditional rules associated with credentials, which can include digitally verified third-party assertions of identity, education, licensing, work history, provenance, authenticity, outcomes, ingredients, etc. through a network of certified primary source or primary source equivalent issuers of credentials. Verifiable data registry technology can be used to provide access to information associated with the credentials, such as validity and schemas. Credential presentation and subscription processes are also utilized. Ecosystem communication and management functions can be executed through various agent instances associated with the actors, including administrators. Rating systems and fee transactions are also managed.
