Solution Overview

Problem

Wireless devices can access and store sensitive information without requiring a subscription, making them vulnerable to unauthorized access if lost or stolen, and allowing unauthorized users to access data when loaned to others.

Innovation Solution

Implementing a system where a wireless device communicates with an external security information source to verify user identification, determining whether secure data can be accessed based on received credentials, preventing unauthorized access by ensuring only intended recipients can view encrypted messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless devices store sensitive information and allow access without subscription, then device functionality and data accessibility are improved, but security and vulnerability to unauthorized access worsen

Engineering Contradiction:

Improvedata accessibilityVSAvoidunauthorized access vulnerability

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary security verification by checking user credentials against an external security information source before allowing access to stored sensitive data. This preliminary action prevents unauthorized access before it can occur, while still maintaining easy accessibility for authorized users.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An external security information source acts as an intermediary between the wireless device and the stored sensitive information. This intermediary verifies user credentials and controls access, allowing the device to maintain both accessibility and security without requiring subscription-based authentication.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If device access is allowed without subscription verification, then ease of operation is improved, but reliability of secure data protection worsens

Engineering Contradiction:

Improvedevice access convenienceVSAvoidsecure data protection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The wireless device autonomously verifies user credentials by communicating with the external security information source without requiring manual subscription verification. This self-service approach maintains ease of operation while ensuring reliable security through automatic credential validation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously verifying user credentials against the external security information source whenever access is attempted. This feedback mechanism ensures that only authorized users can access sensitive data, maintaining reliability without complicating the user experience.

Inventive Principle:

Principle #23Feedback

3Object-affected harmful factors

If external security verification is implemented, then data security is improved, but device complexity worsens

Engineering Contradiction:

Improveunauthorized access protectionVSAvoidsecurity system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The security verification functionality is extracted from the wireless device itself and placed in an external security information source. This extraction reduces device complexity by eliminating the need for embedded security databases and complex verification algorithms, while still providing robust protection against unauthorized access.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Systems and methods for operation upon a data processing device for handling secure data stored on the device. The device is configurable to communicate over a data channel with an external security information source. User identification information is received from the external security information source which identifies a user of the device. The device, based upon the received user identification information, determines whether the secure data stored on the device is to be accessed by a user of the device.
