Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems face challenges in accurately identifying individuals and packages within facilities without relying on cameras, leading to potential false alarms and high costs associated with equipment and installation.
Innovation Solution
A radio-frequency-based identification system that uses transmitters carried by registered individuals and attached to packages, allowing facility-side devices to receive and verify identification signals, eliminating the need for cameras by comparing transmitted identification information with stored data to determine authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If face recognition technology using cameras is introduced to identify pre-registered individuals, then identification accuracy is improved, but equipment cost and complexity increase
Solution Approach 1:
The patent replaces the optical/mechanical face recognition system with a wireless communication-based identification system. Instead of using cameras to capture and compare facial images, the system uses transmitters carried by individuals and readers in the facility to exchange identification information wirelessly, thereby eliminating the need for camera equipment while maintaining identification capability
Solution Approach 2:
The patent uses identification information (such as ID numbers or codes) as digital copies of individual identity rather than using physical facial images. These identification information are stored in databases and transmitted wirelessly, replacing the need for optical capture and image processing, thus reducing equipment requirements while preserving identification accuracy
2Reliability
If face recognition processing is implemented to distinguish residents from intruders, then false alarm reduction is improved, but requirement for residents to turn faces to camera creates operational burden
Solution Approach 1:
The system enables automatic identification without requiring active participation from residents. The transmitters carried by individuals automatically transmit their identification information when entering the facility detection area, and the system automatically compares this information with registered data, eliminating the need for residents to intentionally turn their faces to cameras or provide identification manually
3Reliability
If camera-based identification systems are installed to verify delivery persons, then authentication reliability is improved, but system cost increases
Solution Approach 1:
The patent replaces camera-based visual identification with wireless communication-based authentication. Transmitters attached to or carried by delivery persons transmit identification information that is read by facility-side devices, eliminating the need for expensive camera equipment while maintaining reliable authentication capability through database comparison
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate identification of registered individuals and authenticated packages without cameras, reducing unnecessary notifications and equipment costs while ensuring secure facility access and package verification.
Implementation Method 1
The transmitter transmits an identification signal containing identification information using a radio wave of a predetermined frequency band
Data Source
AI summary
An identification system includes a facility-side device and a transmitter which is carried by a registered individual and transmitting an identification signal containing identification information. The facility-side device includes: an identification signal receiving device receiving the identification signal transmitted from the transmitter; an identification information storage unit in which identification information assigned to the transmitter carried by the registered individual is previously stored; an event detection unit detecting an occurrence of an event; and an individual identification unit determining whether the individual present in the detection area is the registered individual by comparing the identification information, which is exhibited by the identification signal received during a detection time zone, with the identification information stored in the identification information storage unit. The detection time zone is determined according to a detection time of the occurrence of the event and includes at least the detection time of the occurrence of the event.
