Gateway Device Filtering Unwanted Data via Control Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods, such as VGA, require multiple conversions between analogue and digital signals, leading to time-consuming processes and potential data loss, and introduce security risks due to increased attack surfaces from broader data flow capabilities.
Innovation Solution
A method involving a negotiation mechanism along the control channel to filter out unwanted data by checking control data against predetermined protocol criteria, ensuring only wanted data is transmitted through the data channel, thereby reducing the risk of malicious data transfer and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital connection types (e.g., HDMI) are used to transmit data without conversion, then data transmission speed and fidelity are improved, but security risk increases due to broader data flow capabilities
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the first and second devices. This gateway monitors and controls the data flow along the communication pathway, filtering unwanted data packets while allowing legitimate data transmission. The gateway acts as a mediator that maintains the high-speed digital connection benefits while adding security oversight to prevent malicious data transfer.
2Object-affected harmful factors
If control data is filtered to remove unwanted data, then security is improved, but data transmission complexity increases due to protocol checking
Solution Approach 1:
The patent implements preliminary action by establishing predetermined protocol mode criteria before data transmission begins. The gateway device pre-configures acceptable protocol modes and uses these pre-established rules to quickly evaluate incoming data packets. This approach simplifies the filtering process during actual data transmission, as the gateway only needs to check whether data conform to the pre-defined criteria rather than performing complex real-time analysis.
3Manufacturing precision
If protocol mode criteria are strictly enforced, then data fidelity is improved, but adaptability decreases due to limited protocol support
Solution Approach 1:
The patent applies dynamics by making the protocol mode criteria configurable and adaptable. The gateway device can adjust the predetermined protocol mode criteria based on the specific communication needs and data types being transmitted. This dynamic approach allows the system to maintain strict protocol enforcement for data fidelity when needed, while also adapting to support different protocol modes for various application requirements, thus balancing both fidelity and adaptability.

AI summary
There is described a device and method of removing unwanted data from original data for prohibiting unwanted data transfer between a first device and a second device along a communication pathway. The communication pathway includes at least one data channel and at least one control channel. The method includes providing programmable hardware at a position along the at least one control channel. Original data applied to the device includes control data and associated protocol data, the control data including wanted and unwanted data. The control data is checked to determine whether the associated protocol data conforms to at least one predetermined protocol mode criteria at the programmable hardware. The programmable hardware is terminated where the control data is deemed to be unwanted data. The resulting data which is left over is substantially free of unwanted data, enabling associated protocol data transmission along the data channel.
