Title: PROXIMITY DETECTION SYSTEM
Abstract:
Various systems and methods for providing a walk away lock are provided herein. A plurality of data packets may be received at a compute device from a user device. Here, each packet has corresponding time-to-receive value. A baseline latency value of the plurality of data packets may be determined based on their respective time-to-receive values. Additional data packets may be received from the user device, each of these additional data packets having their own corresponding time-to-receive values. A current latency value of the additional data packets may be calculated based on the respective time-to-receive values. A security operation may be performed based on the baseline latency value and the current latency value.
