Document Protection Mechanism for Traceable Restricted Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document sharing systems fail to prevent unauthorized replication and distribution of restricted-access data when shared as editable documents, posing a significant risk to data providers.
Innovation Solution
Implement a document protection mechanism that includes adding duplication identifiers, generating alerts for duplication attempts, and restricting access levels to prevent unauthorized copying and distribution of protected content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If documents are shared as editable documents to enable easy distribution and access, then ease of operation and productivity are improved, but security and control over data replication deteriorate
Solution Approach 1:
The system uses digital watermarking technology to embed invisible duplication identifiers into copied document portions. This allows the system to track and trace unauthorized replications while maintaining the ability to share documents freely. The watermarking technique enables security monitoring without restricting legitimate document distribution and collaboration.
Solution Approach 2:
The server system acts as an intermediary between document creators and recipients, managing document distribution, authentication, and duplication tracking. The server validates user credentials, controls access rights, and monitors document usage, thereby enabling easy distribution while maintaining security through centralized control.
2Reliability
If duplication protection mechanisms are implemented to prevent unauthorized copying, then data security is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The document protection mechanism operates automatically without requiring user intervention. The system self-monitors document access, detects duplication attempts, and embeds watermarks autonomously. This automation maintains strong security while keeping the user experience simple and intuitive.
Solution Approach 2:
The system replaces complex physical security measures with digital watermarking and server-based monitoring. Instead of using cumbersome access controls or physical document protection, the system uses invisible digital identifiers and automated tracking, thereby maintaining security while reducing operational complexity.
3Reliability
If read-only mode is enforced to prevent copying, then data security is improved, but productivity and ease of operation deteriorate
Solution Approach 1:
The system applies different access rights to different users and document portions. Authorized users can edit specific sections while the overall document remains protected. This selective access control enables collaboration on specific areas while maintaining security, thereby balancing productivity with data protection.
Solution Approach 2:
The system allows users to copy and share document portions for legitimate collaboration purposes while automatically embedding watermarks to track the source. This enables productive document sharing and collaboration while maintaining security through traceability, without requiring strict read-only restrictions.
Data Source
AI summary
Methods, systems, and computer-readable storage media for secure document sharing. The method includes receiving, from a server system, metadata associated with a document stored by the server system. The document includes protected data. A user input including a request to access the document stored by the server system is received. The user input is processed to validate the request. A display of the document in a read only mode is generated. A user attempt to duplicate of at least one portion of the document presented for display is detected. A duplication identifier is added to the at least one portion of the document. The duplication identifier is indicative of a duplication source of the document presented for display.
