Providing physical access to a secured space based on high-frequency electromagnetic signaling

A system, comprising:

• at least one processor;
• and
• memory storing instructions that, when executed by the system, cause the system to perform operations comprising:
• identifying a location of a device associated with an authorized user based on a first electromagnetic signal received by at least one first sensor from the device, the first electromagnetic signal having a frequency that is greater than or equal to 300 gigahertz (GHz);
• determining that the location of the device is within a distance of a location of a threshold to a secured space;
• based on determining that the location of the device is within the distance of the location of the threshold, determining that an authentication score indicating that an individual carrying the device is the authorized user is greater than a threshold score, the authentication score being associated with multiple authentication factors identified by the device;
• based on determining that the authentication score is greater than the threshold score, unlocking and/or opening the threshold to the secured space;
• determining, based on a second electromagnetic signal received by at least one second sensor from the device, that the location of the device has moved into the secured space at a first time;
• determining, based on a third electromagnetic signal received by at least one third sensor from the device, that the location of the device has moved out of the secured space at a second time;
• and
• based on determining that the location of the device has moved out of the secured space, causing storage of an indication of the second time and an indication of at least one of the device or the authorized user.

A system for securing a physical space in a building, the system comprising:

• light fidelity (Li-Fi) access points (APs) mounted in the building and configured to receive Li-Fi signals from devices in the building;
• at least one processor that is communicatively coupled to the Li-Fi APs;
• and
• memory communicatively coupled to the at least one processor and storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• identifying, based on the Li-Fi signals, first locations of the devices within the building;
• determining that the first locations of the devices are within a distance of a threshold to a secured space;
• based on determining that the first locations of the devices are within the distance of the threshold, determining that authentication scores indicating that individuals carrying the devices are authorized users are greater than a threshold score, the authentication scores being associated with multiple authentication factors identified by the devices;
• based on determining that the authentication scores are greater than the threshold score, unlocking and/or opening the threshold to the secured space;
• identifying, based on the Li-Fi signals, second locations of the devices within the building;
• determining that the second locations of the devices are within the secured space at first times;
• based on determining that the second locations of the devices are within the secured space, logging entries of the authorized users into the secured space by storing indications of the first times and indications of at least one of the devices or the authorized users;
• identifying, based on the Li-Fi signals, third locations of the devices within the building;
• determining that third locations of the devices are outside of the secured space at second times, the second times occurring after the first times;
• and
• based on determining that the third locations are outside of the secured space, storing an indication of the second times.
