Camera Module Security Control for Lost Device Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices lack effective security measures to prevent unauthorized access and location tracking when lost, leading to potential information leakage and user distress in determining whether to recover or abandon the device.
Innovation Solution
Implementing a method and apparatus that activates a screen lock function with a trigger signal, uses a camera module to capture images when unauthorized access is detected, and outputs these images for security purposes, allowing the device owner to locate the device through other electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screen lock function is implemented to prevent unauthorized access, then security is improved, but the device cannot be accessed by the owner when lost
Solution Approach 1:
The system performs preliminary actions by capturing images and notifying contacts before the device is permanently lost or stolen. The screen lock function is paired with automated image capture and notification mechanisms that activate when unauthorized access attempts occur, allowing the owner to retrieve the device before it falls into permanent unauthorized hands.
Solution Approach 2:
The system establishes feedback loops where unauthorized access attempts trigger image capture, which then notifies predetermined contacts. This feedback mechanism allows the owner to respond to security events in real-time, balancing security protection with the ability to retrieve the device when lost.
2Ease of operation
If the device is left accessible without screen lock, then ease of operation is improved, but unauthorized access and information leakage occur
Solution Approach 1:
The system applies preliminary anti-action by implementing screen lock functions and automated security responses that prevent unauthorized access before it can occur. When the device is lost, the captured images and notifications serve as countermeasures against the harmful effect of unauthorized access.
Solution Approach 2:
The system converts the harmful situation of device loss into a beneficial security opportunity. When unauthorized access is detected, the system captures images and notifies contacts, transforming the security breach into an actionable alert that can lead to device recovery.
3Reliability
If image capture is activated upon unauthorized access detection, then security tracking is improved, but device complexity increases
Solution Approach 1:
The camera module, which is already present in the device for other purposes, is repurposed to serve the additional security function of capturing images during unauthorized access attempts. This multi-functionality approach improves security tracking without requiring entirely new hardware components.
Solution Approach 2:
The device performs self-service security monitoring by automatically detecting unauthorized access attempts, capturing images, and notifying contacts without requiring external monitoring equipment. The device's existing resources (camera, notification system) are leveraged to provide security services.

AI summary
A method for performing security control includes selectively controlling at least one camera module of an electronic device to capture at least one image and outputting the at least one image, for security of the electronic device. For example, the method includes: activating a screen lock function that is associated with a password; and when it is detected that a string that differs from the password is entered, controlling the module to capture the image and outputting the image. In another example, the method includes: activating a remote control function, allowing the electronic device to be remotely controlled, through at least one of a telecommunication network and a wireless local area network, by an application that runs on a processor of another electronic device; and based upon remote control of the application, controlling the camera module to capture the image and outputting the image. An associated apparatus is also provided.
