Cloud Server Signature Validation for Datalink Copyright Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in tracking the usage of digital assets, particularly non-fungible tokens (NFTs), as they rely on the application layer for event triggering, leading to vulnerabilities and difficulties in verifying legitimacy and preventing unauthorized usage.
Innovation Solution
The cloud server and communication devices enable application layer-independent triggering of events by executing them at the datalink layer, using defined signatures embedded in data packets to ensure secure and reliable tracking of digital asset usage across multiple platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If event triggering is performed at the application layer, then the system can process complex application logic, but the tracking reliability and security of digital asset usage is compromised
Solution Approach 1:
The patent extracts the event triggering function from the application layer and relocates it to the network layer. This is achieved by implementing a network layer device that monitors data packets and triggers events based on predefined conditions, independent of application layer processing. This extraction resolves the contradiction by removing the dependency on the application layer for event triggering, thereby improving tracking reliability while reducing the complexity associated with layer dependency.
Solution Approach 2:
The patent introduces a network layer device as an intermediary between the data transmission layer and the event processing layer. This intermediary monitors data packets at the network layer, validates digital signatures, and triggers events without requiring application layer involvement. This mediator approach improves reliability by providing a dedicated security and tracking mechanism that operates independently from application logic complexity.
2Loss of time
If event triggering is performed at the application layer, then application-specific logic can be processed, but latency is increased and unauthorized access cannot be interrupted in real-time
Solution Approach 1:
The patent implements preliminary validation of digital signatures and event conditions at the network layer, before data packets reach the application layer. The network layer device pre-processes and validates data packets, triggering events immediately when conditions are met, without waiting for application layer processing. This preliminary action reduces latency by eliminating the time required for application layer processing while improving security reliability through early validation.
Solution Approach 2:
The patent enables the system to skip the application layer for event triggering by implementing direct network layer event processing. When the network layer device detects predefined conditions in data packets, it triggers events immediately without routing through the application layer. This skipping mechanism reduces latency by bypassing unnecessary processing steps while maintaining security reliability through dedicated network layer validation.
3Reliability
If the application layer controls event triggering, then application protocols can manage digital asset transactions, but vulnerabilities to unauthorized use and abuse increase
Solution Approach 1:
The patent implements preliminary anti-action by validating digital signatures and checking event conditions at the network layer before data packets are processed by the application layer. The network layer device performs security validation in advance, preventing potentially malicious or unauthorized data packets from reaching the application layer. This preliminary security measure improves security reliability by ensuring only valid data is processed while reducing unauthorized access vulnerability through early rejection of invalid packets.
4Loss of information
If digital asset tracking is performed through application layer protocols, then asset usage can be recorded, but the ability to track across multiple platforms and prevent fraud is limited
Solution Approach 1:
The patent implements a universal network layer event triggering mechanism that operates independently of application layer protocols. The network layer device monitors and triggers events for various types of digital assets (NFTs, cryptocurrencies, tokens) using standardized network layer procedures. This universal approach improves tracking accuracy by providing consistent tracking across different platforms and asset types while reducing cross-platform tracking complexity by eliminating the need for platform-specific application layer implementations.
Data Source
AI summary
A cloud server obtains a defined signature from a first communication device, where the defined signature is associated with a digital asset at the first communication device. The cloud server validates the defined signature based on a search of the defined signature in a main action database in the cloud server. The cloud server determines that a copyright check is required for the digital asset associated with the defined signature. The cloud server determines an occurrence of copyright violation for digital asset based on resemblance search of the digital asset in copyright database. The cloud server interrupts data packets of the digital asset from being consumed at the first communication device based on the occurrence of copyright violation determined for the digital asset. The interruption of the data packets is executed at one or more layers different from an application layer of a network architecture at the first communication device.
