Single-Use Access Token Delivery for App-Free Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in accessing physical locations using smartphones due to the need for downloading applications and logging into accounts, which can be time-consuming and unreliable in areas with heavy network load.
Innovation Solution
A system that provides a single-use, time-limited token that can be used to access physical locations without the need for a dedicated application, by generating a one-use token that mimics the optical codes produced by a credentials app, which can be transmitted to a user's device via a messaging service or printed for presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated application is downloaded to the smartphone, then access control functionality is provided, but the download time increases and reliability decreases in areas with heavy network load
Solution Approach 1:
The patent extracts the essential access control functionality from a dedicated application by using a web browser to access a website that generates access tokens. This eliminates the need to download and install a separate application, thereby reducing download time and improving reliability in areas with heavy network load.
Solution Approach 2:
The patent makes the web browser universal by enabling it to perform access control functions in addition to its existing web browsing capabilities. The browser can access the provider's website, generate access tokens, and present them to access control systems, making it a multi-functional device that eliminates the need for dedicated applications.
2Ease of operation
If a dedicated application is downloaded to the smartphone, then access control functionality is provided, but the complexity of the system increases
Solution Approach 1:
The patent extracts the access control functionality from a complex dedicated application and relocates it to a simple web-based interface. Users only need to access a website through their existing browser, eliminating the complexity of installing, configuring, and maintaining dedicated applications while maintaining ease of operation.
Solution Approach 2:
The patent creates a simplified copy of the access control interface on the provider's website that mimics the functionality of a dedicated application. This web-based copy provides the same access token generation and presentation capabilities without requiring users to download or install additional software, thereby reducing system complexity.

AI summary
A system of enhancing biometric analysis matching utilizes an image sensor, such as a digital camera, to capture an image of a face of a person. The system may perform image enhancement, such as edge and contrast enhancement, prior to performing face matching. The enhancement may be localized to a given image region based on determined region illumination. The system may perform image processing and analysis comprising face detection, alignment, feature extraction, and recognition. A biometric recognition confidence indicator may be generated using the results of the image enhancement and analysis. At least partly in response to the biometric recognition confidence indicator falling below a threshold enhancing recognition confidence using an image of visual indicia captured using the image sensor.
