Proximity based identity modulation for an identity verification system

A system comprising:

• a computing device located near a secured asset, wherein the computing device transmits a candidate signal in response to a target user requesting access to the secured asset;
• and
• a non-transitory computer-readable medium comprising stored computer-readable instructions that, when executed by a processor, cause the processor to:
• receive the candidate signal transmitted from the computing device;
• compare the candidate signal to a cluster of signals measured during past successful authentications by the computing device to determine a modulation factor, wherein comparing the candidate signal to a cluster of signals comprises comparing one or more statistical metrics for the candidate signal to one or more statistical metrics for the cluster of signals, the one or more statistical metrics of the candidate signal comprising a mean strength of the candidate signal and the one or more statistical metrics of the cluster of signals comprising a mean strength of the cluster of signals;
• determine a match probability for the target user based on the determined modulation factor, wherein the match probability represents a likelihood that an identity of the requesting target user matches an authenticating identity associated with access credentials recorded at the secured asset;
• and
• grant the requesting target user access to the secured asset in response to determining that the match probability is greater than the operational a security threshold.
