Dynamic Subgroup Messaging with Covert Data Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current message/file exchange applications lack the ability to communicate both overtly and covertly, with selective viewing/hearing of covert data sections and dynamic subgroup creation, which limits privacy and control over data dissemination.
Innovation Solution
The system allows for the communication of messages and files with both overt and covert sections, enabling selective manipulation of covert data through encoding with invisible characters, using second authentication means like NFC or QR codes, and dedicated hardware, allowing dynamic subgroup creation and restrictions based on time, location, and user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If message/file exchange applications use standard encryption methods, then security is improved, but the ability to enable selective viewing/hearing of specific data sections and dynamic subgroup creation is lost
Solution Approach 1:
The message or file is divided into multiple sections, each marked with specific tags that indicate different security levels and access conditions. Overt sections are accessible to all group members, while covert sections require additional authentication or meet specific conditions (time, location, user identity) to be viewed or heard.
Solution Approach 2:
The system dynamically determines which sections of the message/file are visible or audible to each user based on their identity, the current time, location, and other contextual factors. This allows the same message to have different effective contents for different users, resolving the contradiction between uniform security application and selective access capability.
2Ease of operation
If all group members can view all message sections, then ease of operation is improved, but privacy control over covert data is lost
Solution Approach 1:
Different sections of the message have different quality attributes in terms of accessibility. Overt sections are designed to be easily accessible to all members, while covert sections have restricted access conditions. This local differentiation of access quality allows the system to maintain ease of operation for general communication while protecting privacy for sensitive information.
3Loss of information
If multiple authentication methods are required for covert sections, then privacy control is improved, but device complexity increases
Solution Approach 1:
The system uses intermediary elements such as QR codes, NFC tags, or other physical carriers that embed authentication information. Instead of requiring complex multi-factor authentication protocols, the intermediary object itself carries the necessary authentication data, simplifying the user interaction while maintaining strong privacy control for covert sections.
