Image Management System Using Client Identity Encryption for Copyright Tracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image management methods fail to effectively protect image copyrights, as identification information can be easily removed or tampered with, making it difficult to trace the source of image theft and ensuring the rights and interests of the image owner.
Innovation Solution
An image management method that verifies client device authorization before adding an encryption mark to the image using identity information, generating a unique identification code, and storing it, ensuring that if the image is stolen, the source can be traced through the encrypted mark and recorded information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identification information is added to the image in a transparent watermark manner, then the image can be identified as belonging to the owner, but the identification information can be easily erased or tampered with
Solution Approach 1:
The patent applies preliminary anti-action by adding identification information in advance before the image is distributed, and this information is designed to be difficult to remove. The identification information is embedded in a way that creates resistance against subsequent erasure or tampering attempts, thereby preventing the harmful effect before it can succeed.
Solution Approach 2:
The patent implements preliminary action by pre-embedding identification information into the image before distribution. This ensures that the identification information is already in place and cannot be easily removed or tampered with during subsequent use, distribution, or storage of the image.
2Reliability
If identification information is added to the image, then the image owner's rights can be protected, but the responsibility of stealing the image is difficult to trace
Solution Approach 1:
The patent applies feedback by creating a traceable identification information structure that provides feedback about the image's origin and distribution path. When an image is stolen or improperly distributed, the embedded identification information can be detected and used to trace back to the source, providing feedback that enables responsibility tracing.
Solution Approach 2:
The patent uses identification information as an intermediary element that mediates between the image owner and potential infringers. This intermediary contains traceable characteristics that enable the linking of stolen images to their sources, facilitating responsibility tracing while protecting the owner's rights.
3Difficulty of detecting and measuring
If encryption mark is added to the image using client device identity information, then the source of stolen images can be traced, but the image management system becomes more complex
Solution Approach 1:
The patent applies universality by designing the identification information structure to serve multiple functions: it identifies the image owner, provides traceability for responsibility attribution, and can be used for authentication and distribution control. This multi-functionality reduces the need for separate systems, thereby managing complexity while enhancing source tracing capability.
Solution Approach 2:
The patent utilizes parameter changes by modifying the image data structure to include identification information with specific cryptographic properties. By changing the parameters of the image data (adding metadata, encryption marks, or watermarks with specific characteristics), the system achieves traceability without requiring a completely new system architecture.

AI summary
The present disclosure provides an image management method and apparatus, and a storage medium. The method includes: receiving (S102) a download request of a first client device for a first image, and verifying whether the first client device has a download authorization of the first image; in response to the first client device having the download authorization, adding (S 104) an encryption mark to the first image by using identity information of the first client device to obtain a second image; generating (S106) a download identification code for uniquely identifying the second image, and storing the download identification code; and transmitting (S108) the second image to the first client device.
