Beacon Attendance System Invisible MAC Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attendance recording systems face challenges in accurately verifying employee presence using beacon signals, particularly due to the inability to access the MAC address from specific data segments and the risk of fraudulent beacons created by visible characters, leading to incorrect attendance recordings.
Innovation Solution
The system employs a beacon that broadcasts signals with a MAC address and a code containing invisible characters, where the mobile application and server collaborate to decode the code, ensuring that only genuine beacons with matching MAC addresses record attendance, thereby preventing fraudulent recordings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the beacon broadcasts visible MAC address characters, then the attendance recording system can easily identify genuine beacons, but fraudulent beacons can be created by copying visible characters
Solution Approach 1:
The patent applies the principle of making the identification code invisible (analogous to color change) by encoding the MAC address portion in invisible characters. This allows the system to maintain reliability for genuine beacon identification while preventing fraudulent beacon creation, as criminals cannot visually copy invisible characters to create fake beacons.
2Ease of operation
If the mobile application retrieves MAC address from the beacon signal, then attendance recording can be performed, but the application cannot access the MAC address from the first segment
Solution Approach 1:
The patent divides the beacon data structure into multiple segments, with the MAC address stored in an inaccessible first segment and a separate second segment containing encoding information. This segmentation allows the system to maintain ease of operation for authorized applications while protecting the critical identification data from unauthorized access or copying.
Solution Approach 2:
The patent introduces an intermediary encoding mechanism where the second segment contains a code that can be decoded to obtain the MAC address portion. This intermediary layer allows legitimate applications to retrieve the necessary information through proper decoding while preventing direct access to the actual MAC address in the first segment.
3Reliability
If invisible characters are used in the beacon signal code, then fraudulent beacon creation is prevented, but the code cannot be visually verified
Solution Approach 1:
The patent uses an intermediary decoding process where the mobile application or server decodes the invisible character code to retrieve the MAC address portion. This intermediary verification mechanism allows the system to maintain both fraud prevention through invisible characters and verification capability through programmatic decoding, eliminating the need for visual verification.
Data Source
AI summary
This application relates to reporting and monitoring a location of a mobile device. Disclosed is an attendance recording service in which when an employee requests attendance recording using a mobile application installed in a smartphone, the smartphone communicates with a server and records clock-in and clock-out of the employee. When the employee selects an attendance recording request button from the mobile application, an analysis is made as to whether the employee is positioned in a workplace, and clock-in or clock-out of the employee is recorded only when it is determined that the employee is positioned in the workplace, thereby maintaining reliable attendance recording.
