Technology for securely processing emergency response. An emergency response server receives intermittent location data from a client device during non-emergency responses. Upon determining an emergency situation is occurring, the emergency response server sends an unencrypted notification to a client device to activate the client device remotely. Once the emergency response server receives an encrypted message from the client device, the emergency response server sends an encrypted emergency client device, causing the client device to enter an emergency mode. The emergency response server then receives encrypted location information at more frequent intervals from the client device in the emergency mode and displays the location of the client device. Once the emergency situation has ended, the location of the client device is no longer displayed, and a signal is sent to cause the client device to exit the emergency mode.
