Face Authentication Boot Control for Unauthorized Access Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses face challenges in properly authenticating authorized users due to incorrect face registration when users are not facing forward during login authentication, leading to unauthorized system boot-ups.
Innovation Solution
The apparatus employs a dual-processor system for face detection and authentication, where the first processor detects and authenticates faces, and the second processor boots the system only when the face is oriented correctly within a predetermined time frame after successful authentication, registering the face image as the authorized user's ID.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face detection is used for booting the information processing apparatus, then the system can automatically boot when a person approaches, but the apparatus may be booted by unauthorized persons
Solution Approach 1:
The patent performs preliminary face detection and authentication before booting the system. The face detection unit detects the face and the face authentication unit authenticates the detected face against registered authorized user faces before the boot process is triggered, ensuring that only authorized users can initiate system boot-up.
Solution Approach 2:
The system implements feedback by continuously monitoring face detection results and authentication outcomes. When authentication is successful, the system transitions to boot mode; when authentication fails or no face is detected, the system remains in standby state. This feedback mechanism ensures proper authorization before system boot.
2Reliability
If face authentication is performed during login authentication, then authorized users can be identified, but faces not facing forward may be registered incorrectly
Solution Approach 1:
The patent applies local quality by differentiating the treatment of face images based on their orientation. The face detection unit identifies the orientation of detected faces, and only faces with specific orientation characteristics (facing forward) are registered for authentication purposes. This ensures that only properly oriented faces are used for authentication, preventing incorrect registration.
3Speed
If the imaging unit continuously captures images for face detection, then the system can respond quickly to user approach, but power consumption increases
Solution Approach 1:
The patent implements periodic action by having the imaging unit capture images at specific intervals rather than continuously. The face detection unit processes these periodic images to detect faces, and only when a face is detected does the system proceed to authentication and potential boot-up. This periodic imaging approach maintains responsive face detection while significantly reducing power consumption compared to continuous capture.
Data Source
AI summary
An information processing apparatus includes: a memory which temporarily stores a program of a system; a first processor which executes face detection processing to detect an area of each of face images with a face captured therein from among captured images captured by an imaging unit, and face authentication processing to authenticate the face based on information on the detected face image and information on a face image of an authorized user; and a second processor which executes the program of the system to boot the system from a standby state based on a fact that the area of the face image is detected by the face detection processing and face authentication by the face authentication processing is successful.
