Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to provide secure data access to authorized users through light fidelity (LiFi) data transmission and virtual reality devices, as they expose data to cyberattacks and unauthorized access due to reliance on public networks.
Innovation Solution
A system utilizing LiFi devices with processors and light sources to mask and unmask data using blockchain authentication, ensuring secure data transmission within an intranet disconnected from public networks, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transmitted through the Internet, then data accessibility is improved, but data security deteriorates due to exposure to bad actors and cyberattacks
Solution Approach 1:
The patent extracts the data transmission path from the public Internet and relocates it to a private network environment. By removing the connection to public networks and using isolated intranet infrastructure, the system eliminates exposure to external cyber threats while maintaining data accessibility through dedicated private channels.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer for authentication and authorization. The blockchain network mediates between users and confidential data by providing decentralized verification of access rights, enabling secure data transmission without relying on vulnerable centralized Internet infrastructure.
2Productivity
If users are granted access to confidential data, then data utility is improved, but unauthorized access risk increases
Solution Approach 1:
The patent implements a feedback mechanism where the LiFi device continuously monitors and verifies user authorization status through blockchain before transmitting confidential data. The system checks authentication credentials in real-time and adjusts data transmission accordingly, ensuring that only verified authorized users receive confidential information while maintaining efficient data access for legitimate users.
Solution Approach 2:
The patent performs preliminary authentication and authorization verification through blockchain before any confidential data transmission occurs. By pre-validating user credentials and access rights on the blockchain network, the system ensures that only authorized users can receive data, preventing unauthorized access while maintaining smooth data flow for legitimate requests.
3Object-affected harmful factors
If LiFi transmission is used, then network security is improved, but data unmasking control becomes more complex
Solution Approach 1:
The patent implements a self-service mechanism where the LiFi device automatically manages data masking and unmasking operations based on blockchain verification results. The system autonomously determines whether to transmit masked or unmasked data by checking user authorization status on the blockchain, eliminating the need for manual intervention and reducing operational complexity despite the sophisticated security protocols.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively secures data transmission by authenticating users through blockchain and disconnecting from public networks, preventing cyberattacks and unauthorized access, thus enhancing data and network security.
Implementation Method 1
The light source is configured to emit light. The processor is configured to receive, from a receiving device, a first request to provide the confidential data. In response to receiving the first request, the processor masks the confidential data. The processor modulates the light with the masked confidential data.
Data Source
AI summary
A system comprises a light fidelity (LiFi) device. The LiFi device receives, from a receiving device, a first request to provide confidential data. The LiFi device masks the confidential data and modulates light with masked confidential data. The LiFi device emits the light modulated with the masked confidential data toward the receiving device. The LiFi device receives, from a virtual reality device, a second request to unmask the confidential data. The LiFi device communicates a blockchain data entry to a blockchain network, where the blockchain data entry indicates to determine whether a user is authorized to access unmasked confidential data. In response to the user being authorized, the LiFi device receives a confirmation message that indicates the user is authorized to access the unmasked confidential data. The LiFi device modulates light with the unmasked confidential data and emits the modulated light toward the virtual reality device.
