Solution Overview

Problem

Current security systems lack dynamic and efficient mechanisms for updating and managing user privileges, particularly in token-based access control systems, where changes in user or network conditions may require immediate adjustments to access permissions.

Innovation Solution

An apparatus that monitors sessions for accessing resources, detects changes in privileges, communicates risk tokens, and generates tokens to revoke or reassign privileges, facilitating real-time updates and more efficient privilege management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional static privilege management is used, then system simplicity is maintained, but the system cannot respond dynamically to changes in user or network conditions

Engineering Contradiction:
Improvedynamic privilege updatingVSAvoidprivilege management system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic privilege management by continuously monitoring session parameters (user behavior, network conditions, device state) and automatically adjusting privileges in real-time. The system transitions from static permission assignments to dynamic privilege levels that adapt based on current risk assessments, allowing the system to respond to changing conditions without manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system establishes a feedback loop where session monitoring continuously collects data about user behavior and system state, which is then processed to determine risk levels. This feedback mechanism triggers automatic privilege adjustments when thresholds are exceeded, creating a closed-loop control system that adapts privileges based on real-time conditions while maintaining manageable complexity through automated decision rules.

Inventive Principle:
Principle #23Feedback

2Speed

If real-time monitoring and dynamic privilege updates are implemented, then security response time is improved, but processing overhead and system resource consumption increase

Engineering Contradiction:
Improveprivilege update speedVSAvoidsystem processing overhead
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system implements periodic monitoring at strategically determined intervals rather than continuous real-time analysis. Privilege reassignment is triggered by time-based schedules or event-driven conditions, allowing the system to balance security responsiveness with resource conservation. This periodic approach reduces processing overhead while maintaining adequate security response times for detecting and responding to privilege escalation attempts.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts monitoring intensity and sampling rates based on current risk levels and session characteristics. During low-risk periods, monitoring operates at reduced intensity to conserve resources, while high-risk conditions trigger intensified scrutiny and more frequent privilege reassessments. This parameter adaptation allows the system to optimize the balance between security speed and resource consumption based on actual threat levels.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If multiple tokens are used to represent different privilege levels, then access control precision is improved, but token management complexity increases

Engineering Contradiction:
Improveaccess control granularityVSAvoidtoken management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments access control into multiple hierarchical token layers, where each token represents a specific privilege dimension (user identity, device authorization, session validity, risk level). This segmentation allows precise control over different aspects of access while managing complexity through modular token structures that can be independently validated and combined, enabling fine-grained access control without requiring monolithic complex permission systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system merges multiple token validation checks into a unified access decision process. Rather than treating each token as a separate complex management entity, the system combines token verification, risk assessment, and privilege determination into an integrated evaluation framework. This merging approach maintains high access control precision by considering multiple factors simultaneously while reducing overall system complexity through consolidated decision logic.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

According to one embodiment, an apparatus may monitor a session that facilitates a user's access to a resource. The user may be granted a privilege associated with accessing the resource. The apparatus may detect a change associated with the privilege granted to the user in at least one token of a plurality of tokens. The apparatus may then communicate a token that represents the change, and receive a risk token associated with the token. The apparatus may then determine to revoke the privilege based on the risk token, and generate a second token that represents the determination to revoke the privilege. The apparatus may then communicate the second token to facilitate the revoking of the privilege.
