Dual Digital Certificate Architecture for Identity Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital certificate systems face challenges in managing user identities and updating certificates in real-time, as traditional certificates are valid for long durations and do not account for changes in user information.
Innovation Solution
A computerized system for managing digital certificates, comprising a Certificate Authority Computer System (CACS) that issues Proxy Digital Certificates (PCERT) for long-term validation and Transactional Digital Certificates (TCERT) for short-term, transaction-specific use, with multi-factor authentication and real-time validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If digital certificates are issued with long validity durations (one to two years), then the validation process is simplified and less frequent updates are needed, but user identity information may become outdated and security risks increase
Solution Approach 1:
The patent segments the certificate system into two distinct certificate types: Proxy Digital Certificates (PCERT) for long-term validation and Transactional Digital Certificates (TCERT) for short-term transaction-specific use. This segmentation allows the system to maintain both long validity durations for identity verification and short validity for transaction security, resolving the contradiction between certificate duration and identity accuracy.
Solution Approach 2:
The system implements dynamic certificate issuance where TCERTs are generated on-demand for specific transactions with short validity periods, while PCERTs provide stable long-term validation. The certificate validity duration adapts based on the transaction type and security requirements, allowing the system to optimize between long duration and reliability for different use cases.
2Reliability
If digital certificates are updated frequently to reflect current user information, then security and identity accuracy are improved, but validation processes become overloaded and less efficient
Solution Approach 1:
By dividing certificates into PCERT (long-term) and TCERT (short-term), the system reduces the need for frequent validation updates. PCERTs handle stable identity verification over long periods, while TCERTs manage time-sensitive transaction validations, thereby reducing overall validation load while maintaining accuracy.
Solution Approach 2:
The system applies partial validation action by issuing TCERTs only for specific transactions that require current user information, rather than validating all certificates frequently. This selective approach maintains high validation accuracy for critical transactions while avoiding unnecessary validation overhead for stable identity information.
3Device complexity
If a single type of digital certificate is used for all purposes, then the system is simpler to manage, but it cannot provide both long-term validation and short-term transaction-specific security
Solution Approach 1:
The patent creates a universal certificate system where two certificate types (PCERT and TCERT) work together to serve multiple functions: long-term identity validation, short-term transaction security, and on-demand certificate generation. This multi-functional approach provides both simplicity in management and flexibility in usage without requiring entirely separate systems.
Solution Approach 2:
The system dynamically selects which certificate type to use based on transaction requirements. The certificate issuance process adapts to provide appropriate validity durations and security levels for different use cases, making the system versatile while maintaining manageable complexity through a clear dual-certificate architecture.
4Reliability
If multi-factor authentication and real-time validation are implemented for all transactions, then security is enhanced, but processing time and system complexity increase
Solution Approach 1:
The system implements multi-factor authentication and real-time validation selectively for TCERT issuance, not for all certificate operations. PCERT issuance relies on pre-validated user information, reducing processing time for routine operations, while TCERT generation applies enhanced security measures only when needed for specific transactions, balancing security with efficiency.

AI summary
An enhanced certificate authority system and method allows for the enhanced security, validation, and Multi-Factor Authentication of user's within a digital signature, digital identity and general user data and transaction system through the creation and management of a user's Digital Identity certificate and users data elements to be share in a secure environment, so that through an enhanced certificate authority a user's identity, users general data to be shared and bona fides may be both protected and established across a diversity of electronic devices and transactions.
