Blockchain Consent Verification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively prove and verify consent in digital agreements, particularly in informal settings, due to lack of identity verification, versioning issues, and unreliable documentation, especially in creative industries and emerging markets where formal agreements are not typical.
Innovation Solution
A system utilizing a network, user device, server, and blockchain to record and verify consent by obtaining an object of consent, combining identity or permission information, and storing a consent record within the blockchain, ensuring a secure and transparent agreement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital signing systems are used, then consent can be recorded, but identity verification and proof of consent contents cannot be ensured
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between the digital signing system and the consent verification process. The blockchain stores cryptographic proofs of consent and identity information, acting as a trusted mediator that enables verification without requiring complex centralized authentication systems. This resolves the contradiction by providing reliable consent proof through the blockchain's decentralized verification mechanism while avoiding the need for overly complex traditional digital signing infrastructure.
Solution Approach 2:
The patent creates cryptographic copies of consent information and identity data that are stored on the blockchain. These cryptographic representations serve as immutable proofs that can be verified without accessing the original complex authentication systems. By copying and hashing consent data onto the blockchain, the system enables reliable verification while keeping the underlying system architecture simpler.
2Reliability
If formal agreement documents are required, then consent can be documented, but accessibility and ease of use decrease in informal settings
Solution Approach 1:
The patent enables users to self-generate cryptographic proofs of consent directly on their devices without requiring formal legal documentation or lawyer intervention. The system automatically creates verifiable consent records through cryptographic operations performed by the user's own device, making the process as easy as informal agreement while providing documentation reliability comparable to formal contracts.
Solution Approach 2:
The patent changes the fundamental parameter of consent documentation from physical/legal documents to cryptographic data structures. By transforming consent into a digital cryptographic proof that can be stored and verified on a blockchain, the system achieves formal documentation reliability while maintaining the simplicity and accessibility of informal agreement processes.
3Measurement precision
If version control is implemented for agreements, then documentation accuracy improves, but system complexity and difficulty of verification increase
Solution Approach 1:
The patent implements preliminary hashing of agreement versions before they are committed to the blockchain. Each version of the agreement is cryptographically hashed in advance, creating a unique fingerprint that is stored on the blockchain. This preliminary action enables precise version tracking and verification without requiring complex real-time version control systems, as the cryptographic hashes provide immutable proof of each version's contents.
4Reliability
If biometric data is used for consent verification, then identity authentication improves, but privacy concerns and system complexity increase
Solution Approach 1:
The patent extracts only the essential cryptographic proof of identity from biometric data without storing or processing the actual biometric information. The system takes out the verification capability from the biometric data itself and represents it as a cryptographic signature or proof that can be verified without accessing the sensitive biometric source material, thereby maintaining identity verification reliability while reducing privacy concerns and processing complexity.

AI summary
Apparatuses, systems, and methods are described for selectively performing one or more operations relating to an object of consent. The system includes (i) a network, (ii) a user device having an input device and configured to obtain an object of consent from a user of the user device via the input device, (iii) a server having a storage and configured to receive the object of consent from the user device, to perform at least one data processing operation associated with the object of consent, to store a result of the data processing operation at the storage, and to generate an agreement object associated with the object of consent, and (iv) a blockchain configured to receive the agreement object, to combine at least one of identity information or permission information associated with the agreement object, and to selectively store a consent record by the blockchain.
