Solution Overview

Problem

Users in extended reality environments abuse restricted resource access by repeatedly accessing resources using different credentials or identities, exceeding usage constraints.

Innovation Solution

Implement an access control system that monitors biometric and behavioral characteristics of users, compares them against stored profiles, and inhibits access or adjusts usage based on matching profiles to prevent abuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If access control is implemented with credentials and constraints, then resource access is restricted and protected, but users can abuse the system by switching between different credentials to exceed usage limits

Engineering Contradiction:
Improveaccess control reliabilityVSAvoidcredential flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system continuously monitors user behavior and resource access patterns, comparing actual usage against defined constraints. When a user approaches or exceeds their allocated resources, the system provides feedback by blocking further access attempts with that credential, thereby preventing abuse while maintaining legitimate access control

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The access control system evolved from simple credential-based authentication to a multi-functional system that simultaneously performs authentication, authorization, usage monitoring, and abuse detection across multiple credentials. This universal approach allows the same system to handle both legitimate credential variations and detect coordinated abuse patterns

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

2Ease of operation

If multiple credentials are permitted for user access, then user convenience and access flexibility are improved, but the risk of resource abuse through credential switching increases

Engineering Contradiction:
Improveaccess convenienceVSAvoidresource abuse risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system monitors access patterns across multiple credentials and provides feedback when abuse is detected. When the same user is identified using multiple credentials to exceed resource constraints, the system blocks further access attempts, thereby maintaining convenience for legitimate multi-credential use while preventing abuse

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The access control system acts as an intermediary between users and resources, mediating access requests by evaluating not just individual credentials but also the collective pattern of usage across multiple credentials. This intermediary function allows legitimate flexibility while blocking abusive patterns

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If usage constraints are enforced on restricted resources, then resource availability is controlled and protected, but legitimate users may be incorrectly blocked when using different credentials

Engineering Contradiction:
Improveconstraint enforcementVSAvoidlegitimate access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system provides intelligent feedback by analyzing the context and pattern of access attempts. Legitimate users accessing resources with different credentials for valid reasons are not blocked, while users attempting to circumvent constraints through credential switching are identified and blocked. The feedback mechanism distinguishes between legitimate multi-credential access and abusive patterns

Inventive Principle:
Principle #23Feedback

AI summary

A computer implemented method of controlling access by a requesting user to a restricted resource in an extended reality environment, the method comprising: permitting access, by the requesting user, to the restricted resource; monitoring characteristics of the requesting user during use of the restricted resource, the characteristics including one or more of biometric and behavioural information for the user accessing the resource; accessing a profile data store containing a plurality of profiles of users having accessed the restricted resource, each profile including at least one of biometric and behavioural information for a respective user accessing the resource; responsive to a determination that the characteristics of the requesting user corresponds to at least one profile, inhibiting access, by the requesting user, to the restricted resource.
