Invisible Barcode Touch Transmission for Secure Device Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch technologies face challenges in efficiently transmitting signals between touch devices to enable seamless operation in application modes, such as unlocking devices or establishing network connections, often requiring complex handshaking processes and visible codes, which can be insecure and time-consuming.
Innovation Solution
A transmission system utilizing invisible barcodes formed by specific electrode patterns on touch panels, allowing touch devices to operate in application modes by emitting and receiving signals based on motion or rotation, enabling secure and rapid data transmission and device unlocking without visible codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visible barcodes are used for device unlocking, then data transmission can be achieved, but security is compromised and the process becomes time-consuming
Solution Approach 1:
The patent applies the principle of color changes by transitioning from visible barcodes to invisible barcodes that utilize invisible light spectra (such as infrared or ultraviolet). This allows the barcode to be imperceptible to human eyes while still being detectable by specialized sensors, thereby enhancing security and reducing the time required for device unlocking without compromising data transmission capability
2Reliability
If complex handshaking processes are used for device communication, then connection reliability is improved, but operation complexity increases
Solution Approach 1:
The patent extracts and eliminates the complex handshaking processes from the device communication protocol, replacing them with a simplified invisible barcode transmission mechanism. The invisible barcode contains all necessary authentication and connection information in a single transmission, removing the need for multiple back-and-forth communication steps while maintaining connection reliability
3Productivity
If traditional touch device communication is used, then device operation is achieved, but data transmission efficiency is reduced
Solution Approach 1:
The patent replaces the traditional mechanical/electrical touch device communication system with an optical-based invisible barcode transmission system. By using invisible light spectra and optical sensors, the system achieves much faster data transmission efficiency while simplifying the communication protocol, as the invisible barcode can transmit multiple data points in a single static image rather than requiring sequential signal exchanges

AI summary
A transmission system includes a first touch device and a second touch device. The second touch device includes a transmission region and the transmission region forms an invisible barcode. The first touch device and the second touch device work together to operate in a touch mode or in an application mode. When the first touch device and the second touch device work together to operate in the application mode, the transmission region uses the invisible barcode to transmit a transmission signal to the first touch device to unlock the first touch device.
