Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing authentication methods for securing communications between agent and user devices are unreliable due to inconsistent network connections and inefficient use of computational resources, leading to potential insider attacks and spoofing, and traditional two-factor authentication methods are prone to guessing and computational burdens.

Innovation Solution

Implementing a security system that uses machine learning techniques to predict and customize content items for user and agent devices to authenticate each other, utilizing images, text strings, and graphical icons for secure communication verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional two-factor authentication methods are used, then authentication can be performed, but the system is prone to guessing attacks and computational burdens

Engineering Contradiction:

Improveauthentication securityVSAvoidcomputational burden

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses content items (images, text strings, graphical icons) as authentication tokens that are copied and transmitted between devices. Instead of complex cryptographic computations, the system relies on matching copied content items, significantly reducing computational burden while maintaining security through the unpredictability of the content selections

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The authentication system uses temporary, single-use content items that are generated, transmitted, and then discarded. Each authentication event uses fresh content items that never need to be stored long-term, reducing both computational overhead and storage requirements while preventing replay attacks

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Speed

If agent devices store authentication data locally, then authentication speed improves, but storage and memory resources are limited

Engineering Contradiction:

Improveauthentication speedVSAvoidstorage capacity

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential authentication elements (content item selections) from the full authentication data set. Instead of storing complete authentication credentials, the system extracts and transmits only the necessary content item identifiers, minimizing storage requirements while enabling rapid authentication verification

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Content items are pre-generated and stored on the server side before authentication events occur. This preliminary preparation allows agent devices to quickly retrieve and use authentication content without performing complex local computations or storing large authentication data sets

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If network connections are used for authentication, then remote authentication is enabled, but inconsistent network connections make authentication unreliable

Engineering Contradiction:

Improveremote authentication capabilityVSAvoidauthentication reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system prepares authentication content items in advance and transmits them before the actual authentication event. This cushioning approach ensures that even if network connections are intermittent or unreliable during the authentication moment, the pre-transmitted content items are already available for immediate verification without requiring real-time network connectivity

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The authentication mechanism uses copied content items that can be transmitted once and then verified locally without requiring continuous network connection. The content items serve as self-contained authentication tokens that work offline, enabling reliable authentication despite inconsistent network conditions

Inventive Principle:

Principle #26Copying

AI summary

In at least some embodiments, systems and methods of the present disclosure enable content selections for securing communications between agent devices and user devices. A request is received for a communication between an agent device and a user device. A user record associated with the user device is determined based on the characteristic. The security system may obtain content items for authenticating the agent device for the user device with the user record. A set of the plurality of content items are determined for display to the agent device. The set of the plurality of content items are transmitted to the user device associated with the user record. A content item identified by a content item selection is received. A match is determined between the selected content item and the set of content items. The communication is transmitted, responsive to the match, with a predetermined type data request for the user device to satisfy the authentication request.
