Bluetooth transmission security pattern

A non-transitory computer-readable medium comprising instructions configured to cause at least one processor to perform a method comprising:

• receiving, at a computer, a plurality of beacon messages associated with a plurality of received power levels, the plurality of beacon messages received in a sequence from the beacon device;
• determining, at the computer, a plurality of authentication values associated with each of the plurality of received power levels based upon a reference power level, wherein determining the plurality of authentication values associated with each of the plurality of received power levels based upon the reference power level comprises quantizing the plurality of received power levels using the reference power level;
• and
• validating, at the computer, the beacon device using the plurality of authentication values.

A beacon device comprising:

• at least one transmitter;
• at least one processor configured to:
• determine a plurality of power levels at which to transmit a plurality of beacon messages;
• and
• cause the at least one transmitter to transmit the plurality of beacon messages at a plurality of power levels, the plurality of power levels comprising different power levels, the plurality of power levels associated with a plurality of authentication values, wherein the plurality of power levels are quantized based on a reference power level so as to determine a plurality of authentication values associated with each of the plurality of power levels based upon the reference power level.
