Proximity detection system
First Claim
1. A device of providing a walk away lock, the device comprising:
- a transceiver to;
receive a plurality of data packets from a user device, each packet having corresponding time-to-receive values; and
receive additional data packets from the user device, each of the additional data packets having corresponding time-to-receive values; and
a controller to;
determine a baseline latency value of the plurality of data packets based on the respective time-to-receive values;
calculate a current latency value of the additional packets based on the respective time-to-receive values; and
perform a security operation based on the baseline latency value and the current latency value;
wherein a particular time-to-receive value of the plurality of time-to-receive values comprises the time period from when the compute device started receiving a first byte of the data packet to when the compute device finished receiving a last bye of the data packet, andwherein to calculate the current latency value includes the controller to average the corresponding time-to-receive values of the additional of data packets.

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.

17. At least one non-transitory machine readable medium including instructions that, when executed by a machine, cause the machine to:
-
receive a plurality of data packets from a user device, each packet having corresponding time-to-receive values; determine a baseline latency value of the plurality of data packets based on the respective time-to-receive values; receive additional data packets from the user device, each of the additional data packets having corresponding time-to-receive values; calculate a current latency value of the additional data packets based on the respective time-to-receive values; and perform a security operation based the baseline latency value and the current latency value; wherein a particular time-to-receive value of the plurality of time-to-receive values comprises the time period from when the compute device started receiving a first byte of the data packet to when the compute device finished receiving a last bye of the data packet, and wherein to calculate the current latency value, the instructions cause the machine to average the corresponding time-to-receive values of the additional of data packets. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
