Solution Overview

Problem

Existing content sharing systems lack effective mechanisms to enforce conditions on user operations, such as permission requirements and location-based access, leading to potential misuse or unauthorized access to shared content.

Innovation Solution

A system that enables users to share content with conditions, using verification mechanisms like QR codes and credential identifiers to ensure that only authorized users can access and perform operations on the shared content, with features like location-based and temporal restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If content sharing is enabled without verification mechanisms, then ease of operation is improved, but reliability deteriorates due to unauthorized access

Engineering Contradiction:

Improvecontent sharingVSAvoidaccess control

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces QR codes and credential identifiers as intermediary verification mechanisms between content sharers and recipients. These intermediaries enable automated authentication without manual permission requests, resolving the contradiction by maintaining ease of sharing while ensuring reliable access control through cryptographic verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If verification mechanisms are implemented, then reliability is improved, but device complexity worsens

Engineering Contradiction:

Improveaccess controlVSAvoidverification system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service verification where the content sharer's device automatically generates and displays QR codes containing credential identifiers. The recipient's device autonomously scans and verifies these codes without requiring manual intervention from the content owner, reducing perceived complexity while maintaining high reliability through automated cryptographic verification.

Inventive Principle:

Principle #25Self-service

3Reliability

If location-based conditions are enforced, then reliability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvepermission enforcementVSAvoidcontent access

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual permission verification with automated location-based access control. The system automatically determines the recipient's location via GPS or other positioning mechanisms and compares it against authorized locations stored in the QR code metadata, eliminating the need for manual permission checks while enforcing reliable geographic restrictions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In one implementation, a computer system receives a request from a first user to perform an operation related to a file stored by the computer system. The file is associated with a second user, and the second user has shared the file with the first user with one or more conditions on the usage of the file by the first user. Based on the first user requesting to perform the operation, the computer system evaluates whether the one or more conditions placed on the usage of the file by the first user allow the first user to perform the operation. Based on evaluation results, the computer system determines that the one or more conditions placed on the usage of the file by the first user allow the first user to perform the operation and authorizes performance of the operation.
