Optical Data Transfer Between Isolated Computing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to efficiently transfer data between unconnected computing devices, particularly when devices are isolated due to incompatibility or security restrictions, preventing unauthorized access but making legitimate data transfer difficult.
Innovation Solution
A method involving an optical sensor, such as a camera, captures an image of the data on a source device, which is then processed using optical character recognition (OCR) on a target device to decode and restore the original data, allowing for secure, quick, and easy transfer without a direct connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are isolated for security reasons, then data security is improved, but data transfer capability deteriorates
Solution Approach 1:
The patent introduces an intermediary medium (display screen and camera) to transfer data between isolated devices. The source device displays encoded data visually, and the target device captures it through its camera, acting as an intermediary that bridges the isolation gap without compromising security protocols
Solution Approach 2:
The patent replaces traditional mechanical/electronic connection systems (wired or wireless connections) with an optical system. Instead of using physical cables or electromagnetic signals that require connectivity, the system uses visual display and optical capture to transfer data across isolation barriers
2Productivity
If optical character recognition is used to process captured images, then data transfer speed is improved, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-encoding data into visually distinct formats (different colors, patterns, or text representations) before display. This preprocessing step simplifies the subsequent OCR process on the target device, as the encoded visual patterns are designed to be easily distinguishable and recognizable by standard image processing algorithms
Solution Approach 2:
The patent changes the parameter representation of data from binary/digital form to visual/optical form (colors, patterns, text). This parameter transformation enables the use of optical sensors and OCR technology, leveraging existing image processing capabilities to achieve rapid data extraction without requiring complex custom processing systems

AI summary
The present invention is directed to a method of transferring a chunk of data between unconnected computing devices. A first chunk of data present in a source computing device can be in a first format that is binary data or nonstandard characters. Encoding, by the source computing device, the first chunk of data to a second chunk of data. The second chunk of data is in a format that is of standard characters. Capturing an image of the second chunk of data by an optical sensor. Receiving of the image by the target computing device. Processing of the image, by the target computing device, to the second chunk of data. Decoding, by the target computing device, the secondary chunk of data to the first chunk of data.
