Secure Data Transmission via Bidirectional Connection Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data exchange systems over communications networks do not adequately protect the transmission path from interception, eavesdropping, and unauthorized access, as they primarily rely on username/password authentication and encryption, failing to continuously verify the identity of users and servers during data transmission.
Innovation Solution
The method involves exchanging a series of client and server connection messages with specific sequences or patterns during data transmission, monitoring these messages for disturbances, and re-authenticating the client if any anomalies are detected, ensuring that only authenticated entities communicate and that data is securely transmitted and stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encryption and authentication methods are used, then data confidentiality is improved, but transmission path security deteriorates
Solution Approach 1:
The patent implements continuous feedback mechanisms through bidirectional connection messages exchanged between client and server during data transmission. These messages provide real-time verification that the communication path remains secure and that both parties are still the authenticated entities, enabling immediate detection and response to any transmission path compromises.
Solution Approach 2:
The system performs preliminary authentication actions by establishing bidirectional connection messages before and during data transmission. This preliminary verification ensures that both client and server are authenticated entities before sensitive data exchange occurs, and continues verification throughout the transmission process.
2Ease of operation
If initial authentication is performed, then user access control is improved, but continuous identity verification deteriorates
Solution Approach 1:
The patent applies continuity by maintaining active verification through bidirectional connection messages throughout the entire data transmission process. Instead of performing authentication only once at the beginning, the system continuously exchanges verification messages to ensure both parties remain authenticated entities throughout the transaction.
Solution Approach 2:
The system implements periodic verification through regularly exchanged connection messages between client and server. These periodic bidirectional messages continuously confirm the identities of both parties at intervals during data transmission, ensuring ongoing authentication without requiring constant manual intervention.
3Reliability
If encryption is applied to data, then data security is improved, but transmission path monitoring deteriorates
Solution Approach 1:
The patent introduces bidirectional connection messages as intermediary elements that travel alongside the encrypted data transmission. These intermediary messages serve as monitoring mechanisms that verify the security of the transmission path without requiring decryption or direct inspection of the encrypted data content, thus maintaining data security while enabling path monitoring.
Data Source
AI summary
A method and apparatus securely transmit data between a client and a server over a communications network. The secure data transmission includes, after the client is initially authenticated, (a) transmitting a series of client connection messages from the client to the server at least while the data is being transmitted, (b) transmitting a series of server connection messages from the server to the client at least while the data is being transmitted; (c) monitoring the client connection messages at the server; (d) monitoring the server connection messages at the client; (e) if a disturbance is found either in the client connection messages or the server connection messages, terminating the data transmission between the client and the server, re-authenticating the client, and re-transmitting the data; and (f) if the encrypted data is successfully transmitted to the server, storing the data in a database associated with the recipient.
