Selective Media Content Obfuscation via Reversible Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems lack effective security measures to protect specific portions of media files from unintended exposure, as they typically apply security protocols at the platform level rather than at the content level, leaving private information vulnerable to unauthorized access.
Innovation Solution
The implementation of computerized systems and methods that enable selective obfuscation of media file content by reversible encoding, allowing only authorized users to decode and access sensitive information, using encryption keys to secure and obfuscate content within media files, compatible with various encoding schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If platform-level security protocols are applied to media files, then security coverage is provided at the system level, but specific portions of content remain vulnerable to unauthorized access
Solution Approach 1:
The patent divides the media file into multiple segments or portions, applying security measures to specific segments rather than the entire file. This allows selective protection of sensitive portions (e.g., faces, private information) while leaving other portions accessible, thereby resolving the contradiction between providing security and maintaining content accessibility at the appropriate granularity level
Solution Approach 2:
Different portions of the media file are assigned different security characteristics. Sensitive content is encrypted or obfuscated while non-sensitive content remains unprocessed. This local differentiation of security properties enables the system to protect only where needed, improving security effectiveness without unnecessarily restricting access to the entire media file
2Reliability
If selective obfuscation of media content is implemented, then privacy protection for specific portions is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary processing layer that handles the complexity of identification and obfuscation. This intermediary component (such as a processing server or module) automatically detects sensitive portions and applies obfuscation, shielding the user interface from complexity while maintaining privacy protection capabilities
Solution Approach 2:
The system performs automatic identification and obfuscation of sensitive content without requiring manual user intervention. The processing system autonomously analyzes media files, identifies protected portions, and applies security measures, thereby reducing the operational complexity burden on users while maintaining strong privacy protection
3Reliability
If reversible encoding is applied to protect content portions, then authorized access control is improved, but processing time increases
Solution Approach 1:
Instead of encrypting the entire media file, the system applies reversible encoding only to the necessary minimum portions that contain sensitive information. This partial action approach maintains strong access control for protected content while minimizing the overall processing time required compared to full-file encryption
Solution Approach 2:
The system performs content analysis and identification of sensitive portions before applying obfuscation. By preliminarily determining which portions need protection, the system can efficiently apply encoding only to those specific areas, reducing unnecessary processing time while ensuring comprehensive access control for all sensitive content
