Blockchain Identity with Multi-Level Data Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity management systems lack effective methods for remote identity proofing, especially in digital environments, and fail to provide granular control over sensitive identity data access, which is crucial for secure payroll transactions and employee verification.
Innovation Solution
A distributed ledger system, utilizing blockchain technology, encrypts multi-level identity data with digital public keys, allowing employees to control access levels and grant permissions to third parties, combining public key infrastructure and payroll cloud services for secure and remote identity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If identity data is stored in a distributed ledger for remote identity proofing, then identity verification capability is improved, but data security and access control become more complex
Solution Approach 1:
The patent segments identity data into multiple sensitivity levels (e.g., public information, private information, confidential information). Each level is stored in the distributed ledger with different access permissions, allowing remote identity proofing while maintaining granular control over what information is accessible to third parties.
Solution Approach 2:
The patent applies different access control policies to different portions of identity data based on their sensitivity levels. Third parties can access only the specific level of data required for their purpose, while more sensitive data remains protected. This allows versatile identity verification while keeping access control manageable through localized permission settings.
2Reliability
If all identity data is made accessible for verification, then identity proofing effectiveness is improved, but data privacy and security are compromised
Solution Approach 1:
The patent implements partial action by allowing third parties to access only the specific level of identity data required for verification purposes. Instead of exposing all identity information, the system provides sufficient data for reliable identity proofing while withholding excessive information that would compromise privacy. For example, a third party may only need to verify basic identity attributes rather than accessing sensitive personal information.
3Object-affected harmful factors
If granular access control is implemented for multi-level identity data, then data security is improved, but system complexity increases
Solution Approach 1:
The patent adds a dimensional layer to identity data storage by organizing data across multiple sensitivity levels rather than a single flat structure. This dimensional organization allows the system to maintain simple access control rules at each level while achieving comprehensive security through the layered architecture. The multi-level structure enables granular security without requiring complex permission management for every individual data element.
Data Source
AI summary
A method of using a distributed ledger maintained solely in a computer network. Wage payment information is received from an employer regarding an employee. A copy of a digital public key uniquely associated with the employee is received. A transaction is issued to the distributed ledger at a time of wage issuance, along with identity data encrypted with the digital public key, the identity data uniquely associated with the employee, the identity data being multi-level identity data based on levels of data sensitivity, and the identity data including information controllable by the employee to designate which level of the multi-level identity data can be accessed using a data level code and a digital signing key belonging to the employee. A level of the multi-level identity data can be made available to a third party upon being identified with the data level code and upon being decrypted with the digital signing key.
