A management server of an access management system configured to determine whether an authentication condition is satisfied when a user wants to enter a management space such that a manager of the access management system approves or rejects the user's authentication request based on the determined authentication condition, the management server comprising:
- a memory configured to save commands;
- and
- a processor configured to:
- receive, from a user terminal associated with the user, an authentication request for the management space of the access management system and the user's biometric data collected by a plurality of smart wearable devices, the plurality of smart wearable devices including a smart mask including a temperature sensor for body temperature measurement, a fan system for air circulation, an external indicator configured to display fan system status, and a wireless headset including an additional temperature sensor formed in a part that is in direct contact with the user's ear;
- determine whether the user satisfies the authentication condition of the management space based on the biometric data received from the user terminal and a user's authentication data retrieved from a public database, wherein the satisfied authentication condition allows the user to enter the management space;
- send an approval message for the authentication request when the authentication condition is satisfied, and send periodic data requests to the user terminal after the user enters the management space to continuously check whether the authentication condition is satisfied;
- periodically receive, from the user terminal, a position of the smart mask and subsequent biometric data of the user generated in response to the periodic data requests from the user terminal, the biometric data and the subsequent biometric data including a body temperature of the user measured by the smart mask worn by the user;
- send an authentication failure message to the user terminal if the authentication condition is not satisfied based on the subsequent biometric data and the user's subsequent authentication data periodically received while the smart mask is in the management space, wherein the user is not allowed to enter the management space when the authentication condition is not satisfied;
- receive additional biometric data measured by the wireless headset;
- control the fan system included in the smart mask based on at least one of the biometric data, the subsequent biometric data, and environmental data received from the management server, wherein the fan system is configured to adjust an airflow rate in response to changes in the user's breathing rate, body temperature, internal humidity of the smart mask, and external air quality data;
- provide at least one Internet of Things (IoT) wearable function to the user through the user terminal based on the additional biometric data received from the wireless headset, the at least one IoT wearable function including a body temperature correction function provided through the wireless headset such that the user's body temperature measured by the smart mask is corrected through the additional body temperature data measured by the wireless headset;
- calculate a comprehensive health examination score of the user based on the body temperature correction function provided through the wireless headset and the fan system control function provided through the smart mask;
- and
- determine whether the user satisfies the authentication condition by additionally considering whether the comprehensive health examination score exceeds a threshold score set according to an age, a gender, and an occupation of the user.
