Local Face Verification for Secure Delivery Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notification systems fail to adequately protect visitor privacy and secure against impersonation by deliverers, as they often require sending face photos to package delivery company servers.
Innovation Solution
A control method for a notification system that obtains face information of a deliverer from an outside server, captures a visitor's face image using a camera outside the building, verifies the visitor's identity by comparing the images, and notifies the user only when the visitor is confirmed to be the deliverer, thus protecting privacy and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face photos are sent to package delivery company servers for verification, then security against impersonation is improved, but visitor privacy protection deteriorates
Solution Approach 1:
The patent extracts the face verification function from the delivery company server and relocates it to a local notification system. The notification system receives face information from the server, performs local comparison with captured visitor images, and returns only verification results without transmitting actual face photos to the server, thus extracting the harmful data transmission while preserving the verification function
Solution Approach 2:
The notification system acts as an intermediary between the camera system and the delivery company server. It receives face information from the server, compares it locally with captured images, and communicates only verification results to the server, serving as a privacy-protecting mediator that prevents direct exposure of visitor face data to the server
2Object-affected harmful factors
If face information is obtained from outside server and compared locally, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The system segments the verification process into distinct functional modules: a communication unit for receiving face information from the server, a face image checker for performing local comparison, and a notification unit for communicating results. This segmentation allows the notification system to perform verification functions without requiring the entire system to be complex, as each module has a specific, simplified role
Solution Approach 2:
The notification system is designed to perform multiple functions: receiving delivery information from the server, capturing face images via integrated or external cameras, performing local face verification, and notifying users of delivery status. This multi-functionality consolidates what would otherwise require separate systems into one unified device, managing complexity through integration rather than proliferation of components

AI summary
Provided is a control method for a notification system including a notification device located inside a building. The control method includes: (a) obtaining face information of a deliverer of an article from an outside server; (b) obtaining a camera image of a face of a visitor to the building, the camera image being captured by a camera disposed outside the building; (c) verifying whether the visitor is the deliverer by comparing the face information and the camera image; and (d) when the visitor is verified to be the deliverer, notifying, by the notification device, a user of delivery information indicating that the deliverer of the article has arrived at the building.
