Resource Access Control for Image Privacy Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for sharing image files often result in unintentional privacy leakage due to the inclusion of personal information like EXIF data, and the process of removing such information is cumbersome, degrading user experience.

Innovation Solution

A resource access control method that allows for the creation of a target resource copy with modified privacy information, providing options to access either the original or the privacy information-removed copy, simplifying the sharing process by storing the modification settings and allowing direct access to the privacy information-removed copy without re-inputting instructions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If privacy information is removed from image files before sharing, then privacy protection is improved, but the operation process becomes complicated and user experience deteriorates

Engineering Contradiction:

Improveprivacy protectionVSAvoidoperation process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs privacy information removal in advance when the image file is first accessed or shared. The modified copy with privacy information removed is created and stored beforehand, so that subsequent sharing operations can directly use this pre-processed copy without requiring the user to go through the removal process again.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the original image file with privacy information removed. This copy is then used for sharing operations, while the original file remains unchanged. The copy includes metadata indicating it is a modified version, allowing the system to automatically select the appropriate file for sharing.

Inventive Principle:

Principle #26Copying

2Manufacturing precision

If modification instructions are re-input for each sharing operation, then privacy control precision is improved, but time consumption increases and productivity decreases

Engineering Contradiction:

Improveprivacy control precisionVSAvoidsharing efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The system stores the modification instructions (which privacy information to remove) after the first execution. When the same image file is accessed for sharing again, the system automatically retrieves and applies the stored modification instructions without requiring the user to re-input them, thus maintaining privacy control precision while improving efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically manages the privacy information removal process for subsequent sharing operations. Once the user has specified what privacy information to remove the first time, the system handles the entire process autonomously for future operations, including retrieving stored instructions, creating modified copies, and presenting sharing options to the user.

Inventive Principle:

Principle #25Self-service

3Loss of information

If the original image file is used for sharing, then information completeness is improved, but privacy leakage risk increases

Engineering Contradiction:

Improveinformation completenessVSAvoidprivacy leakage risk

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system creates a separate copy of the image file with privacy information removed. This copy is marked with metadata indicating it is a modified version. When the user selects this copy for sharing, the system automatically uses the modified version, ensuring that complete image information is preserved in the original while the shared version has privacy protection.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system separates the image file into two distinct versions: the original file with complete information and the modified copy with privacy information removed. This segmentation allows the user to choose which version to share, with the system providing default options that prioritize privacy protection while maintaining information completeness when needed.

Inventive Principle:

Principle #1Segmentation
