Anti-theft Software Locking Storage Medium Password
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal electronic devices lack effective data theft prevention mechanisms, especially when lost or stolen, as existing security measures are inadequate to protect user-data storage mediums.
Innovation Solution
A data theft prevention system that includes a personal electronic device with an internet-communication interface, BIOS memory, and a processing unit, which, when detected as lost, uses anti-theft software to set a medium password for the user-data storage medium, prohibiting its use, and a server that maintains a lost list to track and recover the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security measures are used, then device operation is maintained, but data security is inadequate when lost or stolen
Solution Approach 1:
The patent applies preliminary anti-action by pre-installing anti-theft software and configuring the system to automatically detect lost states and activate protective measures before data theft can occur. When the device is detected as lost or stolen, the system proactively sets passwords on storage mediums and prohibits device use, preventing unauthorized access before it can happen.
Solution Approach 2:
The patent implements preliminary action by preparing the device with detection capabilities and anti-theft mechanisms in advance. The system continuously monitors its operational state and internet connectivity, and when loss is detected, it immediately executes protective actions such as setting passwords and disabling functionality, rather than reacting after theft has occurred.
2Reliability
If anti-theft measures are activated, then data security is improved, but device functionality is restricted
Solution Approach 1:
The patent applies dynamics by making device functionality adaptive based on operational state. The system dynamically adjusts its security measures and functional restrictions according to whether the device is detected as lost or stolen. When normal operation is confirmed, full functionality is maintained; when loss is detected, protective restrictions are activated. This dynamic adjustment resolves the contradiction between security and functionality.
Data Source
AI summary
Data theft prevention technology for a personal electronic device is provided. When an internet-communication address of the personal electronic device is detected by a server through the internet and the server determines that the detected internet-communication address has been listed in a lost list, a processing unit of the personal electronic device operates in accordance with anti-theft software to execute the codes contained in a BIOS memory of the personal electronic device to set a medium password for a user-data storage medium of the personal electronic device and to prohibit the use of the personal electronic device.
