Proximity User Identification Using Mobile Device Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification techniques for individuals entering or passing by locations, such as stores or buildings, are slow, inaccurate, and expensive due to the use of large databases and low-quality images, leading to high false positives or negatives.
Innovation Solution
A system utilizing a mobile device with a processor and non-transitory storage to register with service providers, obtain network credentials, and transmit unique identifiers to computing devices for accurate identification and customized services, incorporating biometric and non-biometric authentication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional face recognition with large databases is used, then identification accuracy is improved, but identification speed deteriorates
Solution Approach 1:
The patent segments the identification process into two stages: first, rapid filtering using device identifiers (MAC addresses, device IDs) to narrow down candidates; second, more precise biometric verification only for shortlisted individuals. This segmentation resolves the contradiction by enabling fast initial screening while maintaining accurate final identification.
Solution Approach 2:
The system performs preliminary actions by pre-registering device identifiers and biometric data before actual identification is needed. When someone approaches, the system has already prepared reference data, enabling rapid comparison and identification without real-time database searching, thus improving speed while maintaining accuracy.
2Measurement precision
If traditional face recognition with large databases is used, then identification accuracy is improved, but system cost deteriorates
Solution Approach 1:
The patent extracts and utilizes device identifiers (MAC addresses, device IDs) that are already present in mobile devices as an additional identification layer. This extraction eliminates the need to rely solely on expensive, high-precision face recognition systems, reducing overall system cost while maintaining or improving identification accuracy through multi-factor authentication.
Solution Approach 2:
The system introduces device identifiers as an intermediary element between the user and the biometric database. Instead of directly querying the large biometric database for every individual, the system first uses the simple device identifier as a mediator to pre-filter candidates, reducing database query complexity and computational costs while maintaining identification accuracy.
3Measurement precision
If traditional face recognition is used, then identification coverage is improved, but false positive rate deteriorates
Solution Approach 1:
The patent merges multiple identification methods into a unified system: device identifier recognition (MAC addresses, device IDs), biometric data (facial recognition, fingerprints), and contextual information (location, time). This combination creates a multi-layered verification system that significantly reduces false positives while maintaining comprehensive identification coverage, as an individual must match multiple criteria simultaneously.

AI summary
The present disclosure generally relates to a system, comprising a mobile device configured to register with a service provider via an application program, obtain network credentials of communication networks operated by the service provider at various locations, connect to a communication network via the network credentials when approaching a selected location of the service provider, and transmit, to a first computing device via the communication network, a first identifier that uniquely identifies the mobile device. The system also comprises the first computing device positioned at service provider's locations and configured to receive and transmit the first identifier to a second computing device. The system also comprises the second computing device configured to receive the first identifier, compare the unique identifier to a plurality of unique identifiers, and provide a service customized to a user of the mobile device based at least upon the comparison result.
