Automated Device Locking via Periodic Facial Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices lack an automated and secure method to lock or unlock based on authorized user presence, relying on user-initiated settings which can be forgotten or insecure.
Innovation Solution
A method utilizing a camera on the computing device to periodically capture images of users and compare them against stored authorized user images, locking or unlocking the device based on facial recognition matches, ensuring only authorized users can access the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user-initiated locking methods are used, then device can be locked, but user must remember to set it which increases operational complexity
Solution Approach 1:
The system automatically performs facial recognition and locking without requiring user intervention. The camera continuously captures images, the processor automatically compares them against stored authorized user images, and the locking mechanism engages automatically when unauthorized access is detected, eliminating the need for users to manually set locking parameters.
Solution Approach 2:
The system continuously monitors the environment through periodic image capture and automatically responds by locking or unlocking the device based on facial recognition results. This closed-loop feedback mechanism ensures the device adapts its security state in real-time based on who is present, improving both reliability and ease of operation.
2Reliability
If automated facial recognition is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The camera serves multiple functions: it captures images for facial recognition, provides visual feedback to users, and can trigger locking actions. The processor handles both the facial recognition algorithm execution and the locking control logic. This multi-functionality approach improves security through automated facial recognition while minimizing the addition of separate dedicated components.
3Reliability
If continuous image capture is used, then security monitoring is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous capture, the system uses periodic image capture at predetermined time intervals. This approach maintains security monitoring capability while significantly reducing energy consumption compared to continuous operation. The processor can be configured to capture images every N seconds or at specific trigger events, balancing security needs with power efficiency.

AI summary
Disclosed herein are methods, systems, and computer readable media for locking a computing device. Periodic images are received from a camera on a computing device. Each of the images is compared to a stored image of a user. A determination is made that one of the images does not match the stored image, and the computing device is locked upon determining that one of the images does not match the stored image.
