Secure Communication Identifier Translation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems between computer systems are suboptimal from a security standpoint, lacking effective measures to ensure secure data transfer and user authentication.
Innovation Solution
A system and method that utilize encrypted connections validated by digital certificates, white lists, and black lists of IP addresses, along with firm associations and user credentials, to securely transfer data between computer systems without allowing login using the identifier used for data transfer requests, ensuring only approved users can access accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication systems are used between computer systems, then ease of operation is maintained, but security is suboptimal
Solution Approach 1:
The system segments authentication into multiple independent components: IP address validation (white list/black list), digital certificate verification, and user credential authentication. This segmentation allows each security layer to operate independently, improving overall security without requiring complete system redesign.
Solution Approach 2:
The system performs preliminary security validations before allowing data transfer operations. IP addresses are pre-validated against white lists and black lists, digital certificates are verified in advance, and user credentials are authenticated before access is granted. This preliminary action prevents unauthorized operations from occurring.
2Reliability
If user identifiers are used for both login and data transfer requests, then ease of operation is improved, but security is compromised
Solution Approach 1:
The system separates authentication identifiers into two distinct types: login credentials (username/password) and data transfer identifiers (unique request identifiers). This segmentation allows the system to maintain security by not reusing login credentials for data transfer operations, while still providing ease of operation through automated identifier management.
Solution Approach 2:
The system introduces an intermediary authentication mechanism that translates between user-friendly login credentials and secure data transfer identifiers. This intermediary layer (the authentication server and identifier generation system) allows users to operate with simple usernames while the system handles the complex security requirements of unique identifiers for each data transfer request.
3Reliability
If IP address filtering is implemented using white lists and black lists, then security is improved, but device complexity increases
Solution Approach 1:
The system implements self-service IP address filtering by automatically maintaining and updating white lists and black lists based on observed communication patterns and security policies. The system autonomously adds trusted IP addresses to white lists and blocks malicious addresses from black lists without requiring manual intervention, reducing operational complexity while maintaining high security.
Solution Approach 2:
The system performs preliminary IP address validation against white lists and black lists before processing any data transfer requests. This preliminary filtering action occurs automatically at the network layer, preventing potentially malicious communications from reaching higher-level processing, thereby simplifying the overall system architecture by filtering out unwanted traffic early.
Data Source
AI summary
A system and method provides security features for inter-computer communications. A user identifier of the user that cannot be used to log the user in to a data consolidating system is received by a matching system from the data consolidating system. The validity of the user is checked at the matching system and, in response to the checking, the user identifier is converted to a different user identifier and the different user identifier is provided to a data providing system by the matching system. The data providing system provides the data of the user in response, and the matching system forwards the data to the data consolidating system.
