Dynamic Time-Limit Privacy Protection for Monitoring Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing techniques for monitoring cameras lack flexibility and convenience in applying privacy protection measures, as they do not allow for dynamic adjustment of privacy protection settings based on individual time limits.
Innovation Solution
An image processing apparatus that includes an obtainment unit, recognition unit, setting unit, and processing unit to detect and apply privacy protection to images of individuals based on pre-set time limits, using methods such as silhouette conversion, binarization, or mask processing, allowing for flexible and convenient privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional privacy protection techniques are used without time limit settings, then privacy protection can be applied to all detected persons, but it lacks flexibility and convenience in applying processing
Solution Approach 1:
The patent introduces dynamic time limit settings for privacy protection processing. The setting unit allows configuration of specific time limits for each person, and the processing unit automatically determines whether to apply privacy protection based on whether the current time exceeds the set time limit. This dynamic approach enables flexible adaptation to different privacy protection needs while maintaining operational convenience through automated time-based decision-making.
Solution Approach 2:
The patent changes the parameter of time limit configuration to control privacy protection processing. By allowing different time limit parameters to be set for different persons, the system achieves flexible privacy protection application. The processing unit compares the current time with the stored time limit parameter to automatically determine whether to apply anonymization processing, thus resolving the contradiction between flexibility and ease of operation.
2Reliability
If privacy protection processing is applied to all persons in monitoring images, then personal information is protected, but administrative costs increase
Solution Approach 1:
The patent implements dynamic privacy protection based on time limit configurations. The processing unit automatically determines whether to apply privacy protection processing by comparing current time with the time limit set for each person. This dynamic approach ensures privacy protection is applied only when necessary (when time limit is exceeded), maintaining protection effectiveness while reducing unnecessary processing and associated administrative costs.
Solution Approach 2:
The patent uses time limit parameters to control the application of privacy protection processing. By configuring specific time limits for different persons and automatically comparing current time with these parameters, the system achieves cost-effective privacy protection. This parameter-based control eliminates the need for manual review of all images, reducing administrative costs while maintaining reliable privacy protection when needed.
3Measurement precision
If manual review of all monitoring images is performed to determine privacy protection targets, then accurate privacy protection can be applied, but time consumption and administrative burden increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring time limit parameters for each person before monitoring begins. The setting unit stores these time limit parameters in advance, and the processing unit automatically retrieves and compares these pre-set parameters with current time to determine privacy protection application. This eliminates the need for manual review while maintaining accurate identification of privacy protection targets.
Solution Approach 2:
The patent enables the system to automatically determine and apply privacy protection processing without manual intervention. The processing unit self-service by automatically comparing current time with stored time limit parameters and applying anonymization processing when the time limit is exceeded. This automated self-service approach maintains accurate target identification while eliminating time-consuming manual review processes.
