One-Way Data Link for Secure Digital Information Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to securely capture and store specific digital information flowing through shared channels while ignoring all other channel traffic, due to limitations in unidirectional data transfer and compliance with legal and regulatory requirements.
Innovation Solution
A system comprising a channel monitor, a manifest engine, and a storage server that uses a one-way data link and manifest tables to selectively capture and secure information based on programmable selection criteria, ensuring only designated information is recorded and stored, maintaining maximal protection and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bidirectional data transfer systems are used to capture information, then information can be selectively captured and stored, but the system cannot ensure maximal security and integrity protection against unauthorized disclosure or malware
Solution Approach 1:
The system divides the data transfer process into separate unidirectional channels: one for transmitting information to be captured and another for transmitting selection criteria and control signals. This segmentation allows the capture apparatus to receive information without being able to send commands or malware back to the source, thereby ensuring security while maintaining filtering capability through the manifest engine.
Solution Approach 2:
The manifest engine acts as an intermediary component that receives both the information stream and the manifest table containing selection criteria. It compares incoming information against the manifest criteria and selectively passes only matching information to storage. This intermediary function enables intelligent filtering without requiring bidirectional communication between the capture apparatus and information source.
2Reliability
If unidirectional data transfer is implemented to ensure security, then information integrity is protected, but the system cannot dynamically update selection criteria or interact with the information source
Solution Approach 1:
The system pre-configures the manifest table containing all selection criteria before the information capture process begins. The manifest engine loads this comprehensive criterion set in advance, enabling it to dynamically filter incoming information streams without requiring real-time bidirectional communication. This preliminary configuration allows the system to adapt to changing requirements by updating the manifest table while maintaining unidirectional security constraints.
Solution Approach 2:
The manifest table is designed as a dynamic data structure that can be updated with new selection criteria without requiring changes to the underlying unidirectional transfer architecture. The system can modify the manifest contents to reflect changing legal or regulatory requirements, enabling the capture apparatus to adapt its filtering behavior while maintaining the security benefits of unidirectional communication.
3Loss of information
If all information on a shared channel is captured and stored, then complete information availability is achieved, but the system cannot comply with legal requirements to capture only specific information meeting certain criteria
Solution Approach 1:
The manifest engine extracts only the specific information elements that match the criteria defined in the manifest table from the broader information stream. Rather than capturing and storing all incoming data, the system identifies and isolates only those information elements meeting legal or regulatory requirements, thereby reducing storage requirements and ensuring compliance while maintaining complete capture of relevant information.
Solution Approach 2:
The system applies different filtering rules and selection criteria to different portions of the information stream based on the manifest table. Each information element is evaluated against the specific criteria relevant to its type and source, enabling selective capture that complies with varying legal requirements for different categories of information while maintaining overall system simplicity.
Data Source
AI summary
A system is disclosed for monitoring a channel passing information which includes an identifying designation. A channel monitor is coupled to the channel and configured to provide on an output all information passing on the channel. A manifest engine is coupled to the channel monitor to receive the information passing on the channel and to an operator console to receive an information manifest table. The information manifest table contains at least one identifying designation. The manifest engine compares the information received with the information in the information manifest table and only provides on the output that information having an identifying designation that matches an identifying designation included within the information manifest table. A storage server is coupled to the manifest engine and configured to receive and store the information provided from the manifest engine.
