Multi-device Transaction Verification via Device Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic access transactions are susceptible to fraud, with existing security measures often deterring legitimate users due to excessive authentication procedures, leading to significant financial losses and security risks.
Innovation Solution
A system and method that verify transactions by ensuring the presence of a user's portable communication device at a merchant location, using cryptographic patterns and biometric templates to authenticate users, thereby reducing fraudulent transactions without necessitating additional authentication steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple authentication procedures are implemented to increase security, then fraud prevention is improved, but user convenience deteriorates due to excessive authentication steps
Solution Approach 1:
The patent combines multiple authentication factors (device presence detection via base station, biometric authentication, and transaction verification) into a unified authentication system. The server computer integrates these different authentication methods and processes them together to make a single authorization decision, eliminating the need for separate authentication steps and improving user convenience while maintaining security.
Solution Approach 2:
The server computer acts as an intermediary that receives authentication data from multiple sources (base station for device presence, biometric acquisition device for biometric verification) and mediates the authorization decision. This intermediary coordinates the authentication process, preventing fraud through comprehensive verification while presenting a streamlined experience to users by handling complex authentication in the background.
2Reliability
If device presence verification is implemented, then transaction authenticity is improved, but system complexity increases due to additional verification components
Solution Approach 1:
The base station serves multiple functions: it provides wireless communication infrastructure for standard mobile operations and simultaneously performs device presence verification for authentication. By making the base station multi-functional, the system achieves transaction authenticity verification without adding separate dedicated verification hardware, thereby limiting the increase in system complexity.
Solution Approach 2:
The system uses existing infrastructure (base stations and mobile devices) to perform authentication functions. The base station automatically detects the presence of authorized mobile devices without requiring additional user action or specialized equipment. The mobile device itself provides the authentication capability through its presence in the base station's coverage area, eliminating the need for separate verification devices.

AI summary
When a user enters a resource provider location with a portable communication device, the portable communication device provides an indication to a transaction processing system that the portable communication device is currently at the resource provider location. At a later time when the user conducts a transaction with a portable transaction device, the fact that the user's portable communication device had been detected at the resource provider a short time ago is taken into account as a positive indicator that the transaction is not fraudulent. By verifying that both the portable communication device and the portable transaction device are present at the resource provider, the risk of approving a fraudulent transaction from a stolen portable transaction device can be reduced.
