Systems and methods for protecting users

A system for protecting users, the system comprising:

• an identification module, stored in memory, that:
• identifies a first light-and-radio frequency signature that was captured by a security device based on signals emanating from a mobile computing device at a first time and location;
• and
• identifies a second light-and-radio frequency signature that was captured by a same or different security device based on signals emanating from the same mobile computing device at a second time and location;
• a determination module, stored in memory, that determines that the first light-and-radio frequency signature and the second light-and-radio frequency signature match such that an inference is made that an individual possessing the mobile computing device was present at both the first time and location and the second time and location;
• a performance module, stored in memory, that performs, based on the inference that the individual possessing the mobile computing device was present at both the first time and location and the second time and location, a security action to protect a user;
• and
• at least one physical processor configured to execute the identification module, the determination module, and the performance module.

A non-transitory computer-readable medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• identify a first light-and-radio frequency signature that was captured by a security device based on signals emanating from a mobile computing device at a first time and location;
• identify a second light-and-radio frequency signature that was captured by a same or different security device based on signals emanating from the same mobile computing device at a second time and location;
• determine that the first light-and-radio frequency signature and the second light-and-radio frequency signature match such that an inference is made that an individual possessing the mobile computing device was present at both the first time and location and the second time and location;
• and
• perform, based on the inference that the individual possessing the mobile computing device was present at both the first time and location and the second time and location, a security action to protect a user.
