Solution Overview

Problem

Existing call center authentication systems face challenges in effectively preventing spoofing and fraud, as traditional methods such as device authentication and one-time PINs can be bypassed by sophisticated fraudsters.

Innovation Solution

Implementing browser fingerprinting as a second factor of authentication, where a call center system generates a unique browser fingerprint for a caller's device by collecting device-identifying data when the caller accesses a specific webpage, and compares this fingerprint against a database of registered fingerprints to verify the caller's identity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional device authentication is used, then authentication speed is maintained, but security against spoofing and account takeover is insufficient

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The authentication system is segmented into multiple independent verification layers: device authentication, browser fingerprinting, and OTP verification. Each layer operates independently and contributes to the overall authentication decision, allowing the system to maintain security while managing complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces browser fingerprinting as an additional dimension of verification beyond traditional device authentication. By collecting and analyzing multiple browser attributes (user agent, screen resolution, installed fonts, etc.), the system creates a multi-dimensional authentication profile that significantly increases security against spoofing and account takeover attacks

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If one-time PIN authentication is implemented, then security is enhanced, but vulnerability to interception and SIM-swap attacks increases

Engineering Contradiction:
Improveauthentication securityVSAvoidinterception vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent merges browser fingerprinting verification with OTP authentication, creating a combined security mechanism. The browser fingerprint serves as a persistent device identifier that is difficult to intercept or replicate, while the OTP provides temporary verification. Together, they create a dual-layer authentication system that mitigates the weaknesses of each individual method

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary browser fingerprinting authentication before dispatching the OTP. This preliminary verification ensures that the OTP is sent to a legitimate device that has already been verified through browser attributes, reducing the risk of OTP interception by fraudsters who have not yet established browser fingerprint matching

Inventive Principle:
Principle #10Preliminary action

3Reliability

If browser fingerprinting is added as second-factor authentication, then security against spoofing is improved, but system complexity and implementation difficulty increase

Engineering Contradiction:
Improveanti-spoofing capabilityVSAvoidauthentication flow complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The browser fingerprinting system is designed to work across multiple authentication scenarios and devices using universal browser attributes. The same fingerprinting mechanism can authenticate users across different browsers, devices, and authentication flows, reducing implementation complexity through a standardized, multi-functional approach

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an intermediary authentication component that bridges traditional device authentication and browser fingerprinting. This intermediary layer collects browser attributes, generates fingerprints, and compares them against stored profiles, simplifying the integration of browser fingerprinting into existing authentication systems without requiring complete system redesign

Inventive Principle:
Principle #24Intermediary (Mediator)

4Measurement precision

If multiple authentication factors are required, then authentication accuracy is improved, but authentication time and user convenience deteriorate

Engineering Contradiction:
Improveauthentication accuracyVSAvoidauthentication time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system implements partial multi-factor authentication by requiring browser fingerprinting only in specific high-risk scenarios such as new device logins, suspicious activity detection, or account takeover prevention. For routine authenticated sessions, the system relies on existing device authentication, reducing authentication time while maintaining security where most needed

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Embodiments described herein provide for authenticating callers to call centers using browser fingerprinting. A call center system or third-party analytics system includes a server that transmits notifications to a caller device that includes an interactive hyperlink or URL to a particular webpage. When a browser of the caller device navigates to the webpage, the server captures certain types of information about the caller device and generates a browser fingerprint for the caller device. The browser fingerprint is compared against a database of registered browser fingerprints to verify that the caller device of the current call is the registered, expected caller device. The server transmits the notification via any number of communication channels and protocols, such as text messages (e.g., SMS messages, MMS messages), emails, and push notifications associated with client-side software, among others.
