Transaction Security via Nearby Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring the legitimacy of financial transactions in electronic devices is challenging due to the lack of effective methods to verify the authenticity of transactions, particularly in cases where devices may be stolen or compromised.
Innovation Solution
The system enhances transaction security by gathering data from nearby devices using wireless communication technologies, incorporating geolocation, device identifiers, and security scores to evaluate the legitimacy of transactions, allowing for real-time risk assessment and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transaction verification methods are used, then transaction processing is simple and fast, but transaction security and legitimacy verification are insufficient
Solution Approach 1:
The patent combines multiple verification dimensions (device identifiers, geolocation data, network interactions) into a unified transaction request. The user device gathers data from multiple sources and integrates them into a single request that includes device identifiers, location information, and network interaction records, allowing the server to perform comprehensive security assessment without requiring separate verification systems for each factor.
Solution Approach 2:
The patent introduces an intermediary verification layer where the user device acts as a mediator between the transaction initiator and the server. The user device performs preliminary verification by detecting external devices, gathering geolocation data, and constructing transaction requests with security scores before transmitting to the server, thereby reducing the complexity burden on the server while enhancing overall system security.
2Reliability
If comprehensive device data gathering is performed, then transaction legitimacy verification is improved, but processing time and system response time increase
Solution Approach 1:
The patent performs preliminary verification actions at the user device before transaction request transmission. The user device detects external devices, gathers geolocation data, and pre-calculates security scores locally. This preliminary action reduces the amount of data that needs to be transmitted and processed by the server, thereby decreasing overall processing time while maintaining comprehensive verification.
Solution Approach 2:
The patent implements partial verification by focusing on the most critical security factors (device identifiers, geolocation, network interactions) rather than attempting to verify every possible aspect of transaction legitimacy. This selective approach provides sufficient security assurance without the time cost of exhaustive verification.
3Measurement precision
If multiple data sources are integrated, then security assessment accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing task into distinct modules: device identifier collection, geolocation data gathering, network interaction monitoring, and security score calculation. Each module processes specific data types independently, making the overall complex data processing task more manageable and easier to implement while maintaining accurate multi-factor security assessment.
Data Source
AI summary
A user device may detect at least one external device in communication range of the device, receive at least one external device identifier from the at least one external device, generate a transaction request comprising data describing a transaction to be processed and the at least one external device identifier, and send the transaction request to a transaction service for fulfillment. The transaction service may receive the transaction request, analyze the at least one external device identifier to identify at least one security factor associated with the at least one external device identifier, adjust a security score for the transaction based on the at least one security factor, and determine whether to process the transaction based on the adjusted security score.
