Beacon Attendance System Security Code Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attendance recording systems using wireless beacons are vulnerable to abuses such as signal replication and beacon misuse, which can lead to inaccurate attendance tracking.
Innovation Solution
The system employs a smartphone to detect and analyze beacon signals with a unique service ID, hardware ID, and periodically updated security code, ensuring that attendance is only recorded when the employee is within the designated workplace by verifying the beacon's authenticity and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless beacons are used for attendance recording, then ease of operation is improved, but reliability deteriorates due to signal replication and misuse
Solution Approach 1:
The patent applies parameter changes by implementing a security code that periodically changes values stored in the beacon. This dynamic parameter modification prevents signal replication attacks because copied beacons cannot replicate the changing security codes, thus maintaining reliability while preserving ease of operation through wireless attendance recording
Solution Approach 2:
The patent implements feedback mechanisms where the server verifies security codes and beacon identifiers returned by smartphones, and where signal strength measurements provide feedback about beacon proximity. This feedback loop ensures that only authentic beacons within proper proximity can record attendance, resolving the reliability issue while maintaining operational simplicity
2Reliability
If security verification is added to prevent beacon misuse, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing security codes and beacon identifiers in the smartphone before attendance recording. This preparation ensures that verification can occur quickly and efficiently during the actual attendance process, improving reliability without adding significant complexity to the device structure
Solution Approach 2:
The patent uses the server as an intermediary that handles complex security verification operations. The server validates security codes and beacon identifiers, and processes signal strength measurements, thereby improving reliability while keeping the smartphone and beacon devices relatively simple in structure
3Reliability
If signal strength analysis is implemented to detect abnormal activities, then reliability is improved, but loss of time increases due to additional processing
Solution Approach 1:
The patent applies partial action by implementing signal strength analysis selectively rather than for every single attendance event. The system measures signal strength and compares it against thresholds to detect obviously abnormal situations, providing reliable abuse detection without requiring exhaustive processing that would cause significant time delays

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.
