Blockchain Consent Management with Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing consent for services and disclosing confidential information are inefficient and prone to errors, particularly in scenarios requiring multiple consents and secure record-keeping, such as medical services and law enforcement agencies, often relying on paper documents and manual processes.
Innovation Solution
A computer-implemented method using distributed ledger technology, such as blockchain, Hedera Hashgraph, or IOTA Tangle, for secure and immutable record-keeping, combined with a consent management service API, consent requesting API, and consent authorizing application to authenticate and manage signatures for consent, utilizing QR codes and biometric data for secure and tamper-proof consent records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper documents and manual processes are used for consent management, then ease of operation is maintained, but reliability and security of consent records deteriorate
Solution Approach 1:
The patent replaces manual paper-based consent management with an automated digital system using blockchain technology. The mechanical process of signing physical documents is substituted with electronic signature capture via mobile devices, and the manual verification process is replaced with automated cryptographic verification on the blockchain network, thereby improving reliability while managing complexity through automation.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary between consenting parties and service providers. This decentralized ledger acts as a neutral mediator that securely stores and verifies consent records without requiring direct trust between parties, thereby enhancing security while distributing system complexity across multiple nodes rather than concentrating it in a single centralized system.
2Reliability
If distributed ledger technology is implemented for consent management, then reliability and tamper-proof record-keeping are improved, but device complexity and implementation difficulty worsen
Solution Approach 1:
The patent implements a multi-functional consent management system that combines mobile device interfaces, electronic signature capture, blockchain transaction processing, and automated verification capabilities into a single integrated platform. This universal system handles multiple functions (consent collection, verification, storage, and sharing) through a unified architecture, reducing the perceived complexity for users while maintaining the robustness of distributed ledger technology.
3Productivity
If manual consent processes are used, then ease of operation is maintained, but productivity and efficiency of consent management deteriorate
Solution Approach 1:
The patent implements a self-service consent management system where individuals can independently create, store, and share their own consent records through mobile devices. The system automatically handles signature capture, blockchain transaction submission, and verification processes without requiring manual intervention from administrators or service providers, thereby significantly improving productivity while maintaining ease of operation through intuitive user interfaces.
4Measurement precision
If electronic signature capture with biometric data is implemented, then authenticity and non-repudiation of consent are improved, but device complexity and processing requirements worsen
Solution Approach 1:
The patent replaces traditional signature verification methods with biometric authentication using mobile device sensors. Instead of manually verifying signatures against stored samples, the system uses fingerprint scanners, facial recognition, or other biometric sensors built into modern smartphones to automatically verify the identity of the consenting individual, thereby improving measurement precision of authenticity while leveraging existing device capabilities to minimize additional complexity.

AI summary
A computer implemented apparatus and method is provided for authenticating a signature for a consent requiring permission of a person (i.e., a client) to be given for a service by a service provider. In the apparatus, the service provider requests a physical signature from the person. The request is made with a text message or QR code linking to a method for the person to create a signature (for example, a touch screen). The signature and related account and identifying information about the person is entered into a distributed ledger database (DLTD) (e.g., a blockchain database) where it is archived. The service provider can query the DLTD for the signature for consent for the service. Consent can also be provided to third party agencies with a need for consent for information the service provider.
