Description
Technical Field
The embodiment of the invention relates to the technical field of Bluetooth expansion, in particular to a cheating-prevention attendance checking method, device and system.
Background
In order to strengthen attendance discipline, many companies adopt attendance machines to check attendance. Due to the technical development of attendance machines, most companies adopt attendance management systems realized based on a radio frequency card technology or a fingerprint identification technology at present. The radio frequency card is easy to lose, the manufacturing cost is high, the fingerprint attendance needs to be recorded on an attendance fingerprint machine firstly, then the fingerprint attendance is brushed on the fingerprint attendance machine when the employee goes on and off duty, and then attendance information is gathered to a company through a USB (universal serial bus) line or other communication modes to be used as the basis for attendance statistics. The technology requires a lot of manual operations for staff, and causes a lot of staff jam in the work hours. Therefore, bluetooth low energy attendance technology is produced for complete automation.
Bluetooth Low Energy, BLE is also called Bluetooth Low Energy, is a personal area network technology designed and sold by the Bluetooth technical alliance, and is intended to be used for emerging applications in the fields of medical care, sports fitness, beacons, security protection, home entertainment and the like. Bluetooth low energy is intended to significantly reduce power consumption and cost while maintaining equivalent communication range compared to classical bluetooth. The general technical scheme of current BLE attendance is: the method comprises the steps of allocating a unique UUID to each employee, wearing a BLE Slave device for each employee, broadcasting the UUID continuously on a broadcasting channel by the BLE Slave device, installing an attendance machine in a company, wherein the attendance machine is actually a BLE Master device, passively monitoring broadcasts sent by each BLE Slave device, and recording UUID information extracted from broadcasting information. If the UUID is heard, the employee is shown to be in the company, and the earliest and latest time of hearing each day is the working time and the working time of the employee. If not, the employee is not in the company.
Although this method brings great convenience, it has a significant disadvantage for companies that it is easily cheated. For example, a special BLE Slave can be made, which can periodically broadcast UUIDs of all employees once, so that attendance can be completed for all employees as long as such a BLE Slave device is provided, which is not beneficial to attendance supervision of the company on the employees.
