Blockchain Insurance Payments With Encrypted Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blockchain systems are not suitable for interactions that require privacy and permissioned participation, as they are open, decentralized, and permissionless, leading to potential exposure of sensitive information and lack of control over access.
Innovation Solution
Implementing blockchain technology with encryption techniques and digital signatures to control access to personal data, ensuring only authorized nodes can decrypt and view sensitive information, while maintaining a distributed consensus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blockchain systems are used with open, decentralized, and permissionless access, then data transparency and immutability are improved, but data privacy and control over access deteriorate
Solution Approach 1:
The patent applies local quality by differentiating access rights at the data level. Different users or nodes can have different levels of access to different portions of the blockchain data. Encryption techniques are applied selectively to sensitive data while keeping other data accessible, allowing the system to maintain transparency where needed while protecting privacy where required.
Solution Approach 2:
The patent introduces encryption as an intermediary layer between the blockchain data and users. This intermediary mechanism allows the blockchain to maintain its transparent and immutable nature while preventing direct access to sensitive information. The encryption acts as a mediator that can be selectively applied and removed based on user permissions, resolving the contradiction between transparency and privacy.
2Adaptability or versatility
If permissionless access is implemented in blockchain systems, then system openness and decentralization are improved, but unauthorized access to sensitive information increases
Solution Approach 1:
The patent implements local quality by applying different access control mechanisms to different parts of the system. While the blockchain remains open and decentralized for most operations, specific sensitive data is protected with encryption and access permissions. This allows the system to maintain openness where needed while preventing unauthorized access to protected information.
Solution Approach 2:
The patent introduces dynamic access control where permissions can be changed based on user roles, data sensitivity, and contextual factors. The system can transition between more open and more restricted access modes dynamically, allowing it to adapt to different operational requirements while maintaining security against unauthorized access.
3Object-affected harmful factors
If encryption techniques are applied to control access to personal data, then data privacy and security are improved, but system complexity increases
Solution Approach 1:
The patent uses encryption keys as copies that can be distributed to authorized users. Instead of creating complex access control mechanisms, the system uses encrypted copies of data that can be independently managed. Each user receives a copy of the encryption key appropriate to their permissions, simplifying the overall system architecture while maintaining strong security.
Solution Approach 2:
The patent changes the parameter of data accessibility through encryption rather than changing the fundamental blockchain structure. By modifying how data is stored and accessed (through encryption parameters) rather than redesigning the blockchain protocol, the system achieves enhanced security with minimal increase in complexity.
4Reliability
If cryptographic validation is used to maintain data integrity, then data reliability and immutability are improved, but computational requirements and processing time increase
Solution Approach 1:
The patent applies partial cryptographic validation rather than exhaustive verification of all data. Instead of cryptographically validating every single data point and transaction history, the system uses selective encryption and validation mechanisms that apply cryptography only where necessary, reducing computational requirements while maintaining sufficient data integrity.
Solution Approach 2:
The patent performs cryptographic operations in advance during data storage and transaction confirmation, rather than during retrieval and access. By completing the heavy cryptographic validation work beforehand, the system reduces processing time during user operations while still maintaining strong data integrity through cryptographic validation.

AI summary
Methods and systems for processing a blockchain comprising a plurality of immutable insurance policy payment records corresponding to insurance policies are provided. According to certain aspects, a transaction request indicating a policy payment for an insurance policy may be received at a first node. A block including an insurance policy payment record indicating the policy payment may be added to a blockchain and transmitted to another node for validation. The first node may add the block to a copy of the blockchain, where the block may be identified by a hash value that references a previous block in the blockchain that includes at least one additional insurance policy payment record.
