Solution Overview

Problem

Secure data transmissions can be interrupted when the intended recipient's server is down or overloaded, leading to potential data loss or delay.

Innovation Solution

A system that auto-establishes secure connections by identifying an active acquirer server using a distributed channel data format, selecting a primary active acquirer server based on priority and optimal route, and transmitting data securely through a hash encryption process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the intended recipient's server is down or overloaded, then data transmission is interrupted, but implementing a fallback system requires additional device complexity

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-identifying backup acquirer servers and establishing their availability status before the original server fails. When a server goes down, the system already has pre-vetted alternatives ready to immediately receive the data transmission, eliminating the need for complex real-time server discovery and validation processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary mechanism (the server selection module and communication interface) that mediates between the data transmission system and multiple acquirer servers. This intermediary handles the complexity of server monitoring, failure detection, and failover coordination, shielding the core transmission system from direct exposure to server instability while maintaining reliable data delivery.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manual server identification is used when transmission is interrupted, then security may be compromised, but automated selection reduces security control

Engineering Contradiction:
Improvesecure connection reliabilityVSAvoidconnection establishment ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system implements feedback mechanisms where the communication interface continuously monitors server status, data transmission success, and security protocol compliance. This feedback loop enables the system to automatically detect when a server is unavailable or compromised and switch to an alternative server while maintaining security validation, thus achieving both automated operation and security assurance.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs self-service capabilities through automated server selection and validation processes. The communication interface independently evaluates potential backup servers, verifies their security credentials, and establishes connections without requiring manual security approvals. This automation maintains security standards while eliminating manual intervention bottlenecks.

Inventive Principle:
Principle #25Self-service

3Productivity

If data is retransmitted to the original server after failure, then data loss occurs, but switching to a backup server requires additional processing time

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidserver switching time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary server availability checks and establishes a ranked list of backup servers before the original server fails. This pre-positioning of alternative targets eliminates the time-consuming process of searching for and validating backup servers after a failure occurs, enabling immediate failover to the next available server in the pre-established sequence.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adapts the server selection based on real-time conditions. When the original server fails, the system automatically transitions to the next suitable server in the backup list, adjusting the transmission path dynamically without requiring complete re-establishment of the connection. This dynamic switching minimizes interruption time while maintaining transmission efficiency.

Inventive Principle:
Principle #15Dynamics

AI summary

Systems, computer program products, and methods are described herein for auto-establishing secure connections for interrupted data transmissions. The present disclosure is configured to identify an interrupted data transmission comprising a transmission data request; transform the transmission data request to a distributed channel data format to generate a distributed channel data request; transmit the distributed channel data request to an active acquirer switching platform; identify, by the active acquirer switching platform, an acquirer server(s); select, by the active acquirer switching platform, a primary active acquirer server for the distributed channel data request; generate, based on the distributed channel data request and the primary active acquirer server, an acquirer data packet comprising authorized data from at least the transmission data request and device handler data of the primary active acquirer server in the distributed channel data format; and transmit the acquirer data packet to the primary active acquirer server.
