Device Fingerprinting for Website Authentication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Websites face challenges in securely accessing confidential information, as existing methods rely solely on username and password authentication, which may not adequately differentiate between legitimate and potential security risks, especially when accessed from untrusted devices or locations.
Innovation Solution
A system that determines user reputation by analyzing device fingerprinting, including browser fonts, SSID information, and location, to associate users with legitimate or illegitimate entities, thereby granting or denying access based on these attributes, and subjecting potential threats to heightened scrutiny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If username and password authentication is used, then user access is granted, but security against potential threats is insufficient
Solution Approach 1:
The system performs preliminary device fingerprinting and reputation assessment before granting access to confidential information. Device attributes such as browser fonts, SSID information, and location data are collected and evaluated in advance to determine user legitimacy, allowing the system to prepare appropriate access decisions before the user actually accesses sensitive data.
Solution Approach 2:
The patent introduces an intermediary reputation assessment mechanism between the user authentication and information access. This intermediary layer analyzes device fingerprints and compares them against a database of known legitimate and illegitimate device profiles, acting as a mediator that enhances security without requiring direct user intervention or complex authentication protocols.
2Reliability
If device fingerprinting analysis is implemented, then security is enhanced, but system complexity increases
Solution Approach 1:
The security system is segmented into distinct functional modules: device fingerprinting collection, attribute analysis, reputation database querying, and access decision-making. Each module handles a specific aspect of the security assessment, making the overall complex system manageable and maintainable while providing comprehensive security through coordinated operation of these specialized components.
3Reliability
If additional credentials are required, then security is improved, but user convenience deteriorates
Solution Approach 1:
The system performs device fingerprinting and reputation assessment automatically without requiring user action. The browser and device self-provide authentication attributes such as available fonts, SSID information, and location data, which the system analyzes autonomously to determine access eligibility, eliminating the need for users to manually provide additional credentials.

AI summary
A login request to access information associated with a website may be received from a user device accessing the website via a browser. A determination may be made as to whether a browser attribute of the browser, font type, or service set identifier (SSID) information is located within a database. A further determination may be made as to whether to grant access to the information associated with the website. The determination as to whether to grant access to the information associated with the website may be based at least in part on the browser attribute font type, or service set identifier (SSID) information.
