Solution Overview

Problem

Existing systems lack an efficient method for households to share and restrict access to digital content, such as video games, among family members, often requiring device lending or impractical site licenses.

Innovation Solution

A machine learning system analyzes user databases to verify relationships between users, facilitating secure access to shared digital content and allowing users to acquire virtual assets for borrowed applications, while maintaining access restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If device lending is used to share access to digital content, then access can be shared between users, but it becomes impractical and inconvenient for household situations

Engineering Contradiction:
Improveease of sharing accessVSAvoidcomplexity of sharing mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a third-party service provider as an intermediary that manages the digital content sharing process. Instead of users directly lending devices or managing complex sharing arrangements, the service provider acts as a mediator that automatically handles content licensing, access control, and distribution between multiple users in a household environment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates virtual copies or instances of digital content that can be simultaneously accessed by multiple users. Rather than requiring physical device lending, the system generates separate access instances of the same content, allowing multiple users to access the same application or media simultaneously through different devices.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If site license is used to allow installation on multiple computers, then business-related software can be shared, but it becomes impractical for household situations

Engineering Contradiction:
Improveflexibility of content accessVSAvoidpracticality for household use
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic content licensing that adapts to different usage scenarios. The system allows content to be licensed and accessed dynamically based on user profiles, device types, and household contexts, rather than using static site licenses. This enables flexible access arrangements that automatically adjust to changing household needs and usage patterns.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies different access rights and licensing terms to different users and devices within the household. Instead of uniform site licenses, the system tailors content access permissions to individual user profiles, allowing each household member to access content according to their specific rights while maintaining overall system flexibility.

Inventive Principle:
Principle #3Local quality

3Reliability

If access is restricted to application owners only, then security and control are maintained, but family members cannot share access to applications

Engineering Contradiction:
Improvesecurity of content accessVSAvoidability to share with family
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments access rights into different levels and categories. Instead of binary owner/non-owner access, the system creates segmented permission structures that allow partial sharing, temporary access, and role-based permissions. This enables family members to receive controlled access to applications while maintaining owner security and control through hierarchical permission management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary authentication and relationship verification before granting access to family members. The service provider pre-validates user relationships, establishes trust frameworks, and sets up security protocols in advance, allowing secure sharing without compromising owner control. This preliminary action ensures security is built into the sharing process rather than added as an afterthought.

Inventive Principle:
Principle #10Preliminary action

AI summary

In a server configured to operate on a network, secured access to shared digital content may be implemented by analyzing information about a first user and a second user with a neural network trained with a machine learning algorithm to determine a relationship between the first and second users. The first user may be granted access to one or more content items belonging to the second user based on the determined relationship and the second user's access to the one or more content items may be disabled. The first user's access to the content items may be disabled when the second user requests access to them and access of the content items may be returned to the second user after access for the first user to the one or more content items has been disabled.
