Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing security systems for surveillance cameras lack efficient access control mechanisms, allowing unauthorized access to captured images before and after work completion, which compromises security and work efficiency.

Innovation Solution

A device and method that include a registration unit for registering surveillance cameras, an access permission unit for allowing access from worker terminals, and an access prohibition unit to restrict access once work on the camera is completed, ensuring secure and timely access to image data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If access control mechanisms are not implemented in surveillance camera systems, then ease of operation is improved (workers can access camera images without restrictions), but security deteriorates (unauthorized access to captured images is allowed)

Engineering Contradiction:

Improveaccess to camera imagesVSAvoidunauthorized access to images

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The access control system dynamically changes access permissions based on work status. During work periods, access is granted; after work completion, access is automatically revoked. This dynamic adjustment resolves the contradiction by making the system flexible enough to provide ease of operation when needed while maintaining security when work is complete.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses feedback from work status information to control access permissions. When work completion is detected, the system automatically updates access rights to prohibit further access. This feedback mechanism ensures that security requirements are met without manually managing access controls, maintaining both security and operational efficiency.

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If access control mechanisms are implemented in surveillance camera systems, then security is improved (unauthorized access is prevented), but ease of operation deteriorates (workers face access restrictions)

Engineering Contradiction:

Improveunauthorized access to imagesVSAvoidaccess to camera images

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The access control system operates autonomously by automatically granting access when work begins and revoking it when work completes. This self-service capability eliminates the need for manual access management, thereby maintaining ease of operation for authorized workers while ensuring security requirements are met without human intervention.

Inventive Principle:

Principle #25Self-service

3Productivity

If continuous access to surveillance camera images is allowed, then work efficiency is improved (workers can access images at any time), but security deteriorates (images remain accessible after work completion)

Engineering Contradiction:

Improvework efficiencyVSAvoidpost-work access to images

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements periodic access control where access permissions are granted during work periods and automatically revoked after work completion. This time-based periodic action ensures that workers have efficient access during necessary periods while automatically preventing unauthorized access after work ends, resolving the security risk without impacting work efficiency.

Inventive Principle:

Principle #19Periodic action

4Object-affected harmful factors

If access is restricted to surveillance camera images, then security is improved (unauthorized access is prevented), but work efficiency deteriorates (workers cannot access images freely)

Engineering Contradiction:

Improveunauthorized access to imagesVSAvoidwork efficiency

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The access control system dynamically adjusts permissions based on real-time work status. During active work periods, full access is granted to maintain work efficiency; after work completion, access is automatically restricted to maintain security. This dynamic behavior ensures that security measures do not impede work efficiency when access is legitimately needed.

Inventive Principle:

Principle #15Dynamics

AI summary

A device including a registration unit, access permission unit, and an access prohibition unit. The registration unit registers a surveillance camera that is a work target. The access permission unit permits access from a worker terminal to an image captured by the registered surveillance camera via a surveillance network to which the surveillance camera is connected. The access prohibition unit configured to prohibits the access in response to work on the surveillance camera being completed. Security of the image captured by the surveillance camera is thereby enhanced.
