In particular, a geographical location of the user device may be determined. Whether to activate the service may be determined based on the geographical location of the user device. ## Claims ### Claim 1 A method comprising: receiving, by a computing device, a request for a service associated with a first user device; receiving, by the computing device: a first signal from the first user device; and a plurality of signals from a plurality of user devices associated with different geographical locations; estimating the geographical location of the first user device based on a geographical location of a second user device, of the plurality of user devices, that is selected based on comparing spectral characteristics of the first signal with spectral characteristics of a second signal, of the plurality of signals, received from the second user device; and sending, based on the estimated geographical location of the first user device, a message indicating activation of the service. ### Claim 2 (depends on 1) The method of claim 1, further comprising: selecting the second user device from the plurality of user devices based on a similarity between the spectral characteristics, of the second signal received from the second user device, and the spectral characteristics of the first signal. ### Claim 3 (depends on 1) The method of claim 1, further comprising: determining, by the computing device and based on the estimated geographical location, a security level associated with the first user device, wherein the sending is further based on a determination that the security level satisfies a threshold. ### Claim 4 (depends on 1) The method of claim 1, wherein the second user device is selected further based on comparing power characteristics of the first signal with power characteristics of at least one of the plurality of signals. ### Claim 5 (depends on 1) The method of claim 1, wherein the second user device is selected further based on comparing a heartbeat included in the first signal with heartbeats included in the at least one of the plurality of signals. ### Claim 6 (depends on 1) The method of claim 1, further comprising selecting the plurality of user devices from a group of candidate user devices based on at least one of: a device type associated with the first user device; or a service type associated with the service. ### Claim 7 (depends on 1) The method of claim 1, wherein the second user device is selected further based on comparing a signature included in the first signal with signatures included in the at least one of the plurality of signals. ### Claim 8 A computing device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the computing device to: receive a request for a service associated with a first user device; receive: a first signal from the first user device; and a plurality of signals from a plurality of user devices associated with different geographical locations; estimate the geographical location of the first user device based on a geographical location of a second user device that is selected based on comparing spectral characteristics of the first signal with spectral characteristics of a second signal, of the plurality of signals, received from the second user device; and send, based on the estimated geographical location of the first user device, a message indicating activation of the service. ### Claim 9 (depends on 8) The computing device of claim 8, wherein the instructions, when executed by the one or more processors, cause the computing device to select the second user device from the plurality of user devices based on a similarity between the spectral characteristics, of the second signal received from the second user device, and the spectral characteristics of the first signal. ### Claim 10 (depends on 8) The computing device of claim 8, wherein the instructions, when executed by the one or more processors, cause the computing device to determine, based on the estimated geographical location, a security level associated with the first user device, wherein the sending is further based on a determination that the security level satisfies a threshold. ### Claim 11 (depends on 8) The computing device of claim 8, wherein the second user device is selected further based on comparing power characteristics of the first signal with power characteristics of at least one of the plurality of signals. ### Claim 12 (depends on 8) The computing device of claim 8, wherein the second user device is selected further based on comparing a heartbeat included in the first signal with heartbeats included in the at least one of the plurality of signals. ### Claim 13 (depends on 8) The computing device of claim 8, wherein the instructions, when executed by the one or more processors, cause the computing device to select the plurality of user devices from a group of candidate user devices based on at least one of: a device type associated with the first user device; or a service type associated with the service. ### Claim 14 (depends on 8) The computing device of claim 8, wherein the second user device is selected further based on comparing a signature included in the first signal with signatures included in the at least one of the plurality of signals. ### Claim 15 One or more non-transitory computer readable media comprising instructions that, when executed, cause performance of actions comprising: receiving a request for a service associated with a first user device; receiving: a first signal from the first user device; and a plurality of signals from a plurality of user devices associated with different geographical locations; estimating the geographical location of the first user device based on a geographical location of a second user device that is selected based on comparing spectral characteristics of the first signal with spectral characteristics of a second signal, of the plurality of signals, received from the second user device; and sending, based on the estimated geographical location of the first user device, a message indicating activation of the service. ### Claim 16 (depends on 15) The one or more non-transitory computer readable media of claim 15, wherein the instructions, when executed, further cause selecting the second user device from the plurality of user devices based on a similarity between the spectral characteristics, of the second signal received from the second user device, and the spectral characteristics of the first signal. ### Claim 17 (depends on 15) The one or more non-transitory computer readable media of claim 15, wherein the instructions, when executed, further cause determining, based on the estimated geographical location, a security level associated with the first user device, wherein the sending is further based on a determination that the security level satisfies a threshold. ### Claim 18 (depends on 15) The one or more non-transitory computer readable media of claim 15, wherein the second user device is selected further based on comparing power characteristics of the first signal with power characteristics of at least one of the plurality of signals. ### Claim 19 (depends on 15) The one or more non-transitory computer readable media of claim 15, wherein the second user device is selected further based on comparing a heartbeat included in the first signal with heartbeats included in the at least one of the plurality of signals. ### Claim 20 (depends on 15) The one or more non-transitory computer readable media of claim 15, wherein the instructions, when executed, further cause selecting the plurality of user devices from a group of candidate user devices based on at least one of: a device type associated with the first user device; or a service type associated with the service.
