Abstract
Electromagnetic (EM)/radio frequency (RF) emissions may be detected and corresponding EM personas may be created. One or more EM personas may be associated with a super persona corresponding to a particular entity. EM personas, super personas, and/or supplemental identifying information can be used to enforce security protocols.
Claims20
A system, comprising:
- a radio frequency (RF) sensor configured to detect RF signals;
- at least one memory that stores computer-executable instructions;
- and
- an RF controller operationally coupled to a transceiver and the at least one memory, wherein the RF controller is configured to access the at least one memory and execute the computer-executable instructions to:
- receive an RF fingerprint of an RF signal detected by the RF sensor within an area under surveillance (AUS), the RF fingerprint comprising at least one of:
- i) a hardware address of an electronic device that emitted the RF signal or ii) a radio type identifier of a radio of the electronic device;
- identify a first receive signal strength indicator (RSSI) value of the RF signal at the RF sensor at a first time;
- identify a second RSSI value of the RF signal at the RF sensor at a second time;
- determine a velocity of the electronic device based at least in part on the first RSSI value, the second RSSI value, and a span of time between the first time and the second time;
- determine that the velocity is greater than a threshold velocity value;
- determine, based at least in part on the first RSSI value and the second RSSI value, a direction of movement of the first electronic device toward an egress point of the AUS;
- and
- generate an alarm indicating that the velocity of the electronic device toward the egress point has been detected greater than the threshold velocity value.

A method, comprising:
- receiving, by a security system comprising one or more processors, a RF fingerprint of a RF signal detected by an RF sensor within an area under surveillance (AUS), the RF fingerprint comprising at least one of:
- i) a hardware address of an electronic device that emitted the RF signal or ii) a radio type identifier of a radio of the electronic device;
- identifying, by the security system, a first receive signal strength indicator (RSSI) value of the RF signal at the RF sensor at a first time;
- identifying, by the security system, a second RSSI value of the RF signal at the RF sensor at a second time;
- determining, by the security system, a velocity of the electronic device based at least in part on the first RSSI value, the second RSSI value, and a span of time between the first time and the second time;
- determining, by the security system, that the velocity is greater than a threshold velocity value;
- determining, by the security system and based at least in part on the first RSSI value and the second RSSI value, a direction of movement of the first electronic device toward an egress point of the AUS;
- and
- generating, by the security system, an alarm indicating that the velocity of the electronic device toward the egress point has been detected greater than the threshold velocity value.
6 more elements
One or more non-transitory computer-readable media storing computer-executable instructions that responsive to execution cause one or more computer processors to perform operations comprising:
- receiving a RF fingerprint of a RF signal detected by an RF sensor within an area under surveillance (AUS), the RF fingerprint comprising at least one of:
- i) a hardware address of an electronic device that emitted the RF signal or ii) a radio type identifier of a radio of the electronic device;
- identifying a first receive signal strength indicator (RSSI) value of the RF signal at the RF sensor at a first time;
- identifying a second RSSI value of the RF signal at the RF sensor at a second time;
- determining a velocity of the electronic device based at least in part on the first RSSI value, the second RSSI value, and a span of time between the first time and the second time;
- determining that the velocity is greater than a threshold velocity value;
- determining, based at least in part on the first RSSI value and the second RSSI value, a direction of movement of the first electronic device toward an egress point of the AUS;
- and
- generating an alarm indicating that the velocity of the electronic device toward the egress point has been detected greater than the threshold velocity value.
