Transaction Encryption Monitoring With Merchant Failure Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Merchants lack the technical expertise and resources to detect encryption failures in electronic transaction request messages, leading to potential data breaches and compromised security, while service providers face challenges in implementing real-time monitoring and reporting for point-to-point encryption (P2PE) solutions.
Innovation Solution
A system and method for electronic transaction monitoring and reporting that includes a decryption service provider (DSP) to detect unencrypted transaction messages, send failure alerts to merchants, and transmit transaction requests to appropriate acquirer processors, with optional re-encryption, using a decentralized network architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If merchants implement P2PE encryption solution, then payment card data security is improved, but technical expertise and infrastructure requirements increase
Solution Approach 1:
The patent introduces a decryption service provider as an intermediary that performs decryption and monitoring functions. This mediator handles the technical complexity of encryption verification and failure detection, allowing merchants to benefit from secure encryption without requiring specialized technical expertise or infrastructure.
Solution Approach 2:
The system enables automatic detection and alerting of encryption failures through the decryption service provider. The monitoring mechanism operates autonomously to detect unencrypted transactions and notify merchants, eliminating the need for merchants to implement their own complex monitoring infrastructure.
2Reliability
If service providers implement monitoring and alerting controls, then encryption failure detection is improved, but resource requirements and implementation complexity increase
Solution Approach 1:
The patent combines decryption and monitoring functions into a single integrated service provided by the decryption service provider. By merging these functions, the system eliminates the need for separate monitoring infrastructure, reducing resource requirements while maintaining comprehensive encryption failure detection capabilities.
Solution Approach 2:
The decryption service provider performs multiple functions including decryption, encryption validation, failure detection, and alerting. This multi-functional approach allows a single service to replace multiple separate systems, reducing overall complexity and resource requirements for service providers.
3Loss of time
If real-time encryption failure detection is implemented, then response time to security incidents is improved, but system complexity and resource requirements increase
Solution Approach 1:
The system performs encryption validation and failure detection as a preliminary step during the normal decryption process. By embedding monitoring within the decryption workflow, the system achieves real-time detection without requiring separate complex monitoring systems or additional processing steps.

AI summary
A method for electronic transaction monitoring and reporting includes: determining whether the received transaction request is encrypted, upon determining that the received transaction request is not encrypted, sending a failure alert to the merchant, determining a receiving acquirer processor for the transaction request, and transmitting the transaction request to the determined acquirer processor.
