Barcode Secure Booting for Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and potential access issues when trying to boot electronic devices, as they need to remember passwords or carry additional input devices for authentication, which can lead to forgotten credentials and interrupted access.
Innovation Solution
An electronic apparatus equipped with a sensing unit and embedded controller that scans a barcode before booting, allowing the device to continue the booting process if the barcode matches a preset one, eliminating the need for additional input devices and simplifying the authentication process by using a barcode management application to control the sensing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users set password to lock hard disk for data security, then data security is improved, but user convenience deteriorates due to need to remember password and carry additional input devices
Solution Approach 1:
The patent uses a barcode (optical copy) instead of physical password input devices. The barcode contains authentication information that can be scanned optically, replacing the need for keyboards or other input devices. This resolves the contradiction by maintaining security through authentication while eliminating the need to carry additional physical devices.
Solution Approach 2:
The patent replaces mechanical password input (typing on keyboard) with optical scanning (barcode reader). The sensing unit scans the barcode optically and transmits data to the embedded controller, substituting mechanical interaction with optical detection. This improves ease of operation by eliminating physical input devices while maintaining security through the scanned authentication data.
2Adaptability or versatility
If users carry additional input devices for authentication, then authentication capability is improved, but device complexity and portability deteriorate
Solution Approach 1:
The patent makes the sensing unit multi-functional by enabling it to scan barcodes for authentication purposes. The same sensing unit that may already exist for other functions (such as reading product information) is now also used for security authentication. This eliminates the need for separate authentication devices while maintaining authentication capability, resolving the contradiction between versatility and portability.
Solution Approach 2:
The patent merges the authentication function into the existing sensing unit and embedded controller system. Instead of having separate authentication hardware, the barcode scanning capability is integrated into the device's existing optical sensing infrastructure. This consolidation maintains authentication capability while reducing overall device complexity and improving portability.
3Reliability
If traditional password authentication is used, then security control is improved, but access speed and booting efficiency deteriorate
Solution Approach 1:
The patent performs authentication verification during the booting process before the operating system fully loads. The embedded controller checks the scanned barcode against stored authentication data in advance, determining whether to allow system access before resource-intensive OS operations begin. This preliminary security check maintains security control while improving overall booting efficiency by preventing unnecessary OS loading for unauthorized users.
Solution Approach 2:
The patent enables rapid authentication verification by using optical barcode scanning instead of manual password input. The sensing unit quickly captures and transmits barcode data to the embedded controller, which rapidly compares it with stored authentication information. This accelerated verification process maintains security control while significantly reducing the time required for authentication, thereby improving booting efficiency.
