Communication Device Face Authentication Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices struggle to perform access control for multiple users sharing a single device or when users temporarily borrow devices connected via a wireless LAN, as existing methods fail to accurately authenticate each user.
Innovation Solution
A communication device that stores device and user identification information associated with face images, captures user images, and authenticates devices based on matching face images, allowing for precise access control on a user-by-user basis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If device-by-device authentication is performed using preregistered device IDs, then access control on a device basis is achieved, but access control on a user basis cannot be performed when multiple users share one device
Solution Approach 1:
The authentication system is segmented into two independent components: device identification (using device ID) and user identification (using face images). This segmentation allows the system to perform both device-by-device authentication and user-by-user authentication simultaneously, resolving the contradiction between maintaining device-level security and enabling user-specific access control for shared devices.
Solution Approach 2:
Face images serve as an intermediary authentication element between the user and the device. The captured face image is compared against preregistered face images to identify the user, while the device ID identifies the device. This intermediary mechanism enables user-specific access control without compromising device-level security.
2Adaptability or versatility
If biometrics authentication using fingerprints or vein patterns is used, then user authentication is achieved, but the device cannot identify which specific device is being used
Solution Approach 1:
The system merges two authentication methods: biometrics authentication (using face images) for user identification and device ID-based authentication for device identification. By combining these methods, the system simultaneously achieves both user-specific access control and accurate device identification, resolving the contradiction between the two requirements.
3Adaptability or versatility
If face image comparison is performed for user authentication, then user-by-user access control is enabled, but the system cannot determine which device the user is accessing
Solution Approach 1:
The system performs preliminary registration of both device IDs and face images before authentication. During authentication, the previously registered device ID is used to identify the device, while the registered face images are used to identify the user. This preliminary action ensures that both device identification information and user identification information are preserved and can be used simultaneously.

AI summary
A communication device, operable to communicate with an electronic device via a network, may include a storage section, an image capturing section, and an identification section. The storage section may store device identification information identifying the electronic device and one or more face images of one or more users that use the electronic device while associating the device identification information with each of the face images of the users of the electronic device. The image capturing section may capture an image of a face of the user of the electronic device. The identification section may identify the electronic device on the basis of the device identification information stored in association with one of the stored face images that matches the captured image of the face of the user of the electronic device.
