Abstract

An organization can subscribe to an emergency notification service for alerting emergency service providers when an emergency occurs at a site of the organization, such as an emergency that necessitates a lockdown situation. When an emergency service provider is alerted that a lockdown is in effect, the emergency service provider dispatches responding officers to the scene. Once the responding officers have addressed the situation and it is safe to exit the lockdown, the officers may attempt to access the locked rooms to evacuate the occupants. To verify the identity of an officer seeking access to a room, the officer or a room occupant requests an access phrase via their mobile device. The emergency service provider generates a distinct access phrase and sends it to the officer and the occupant so that when the officer speaks the access phrase the occupant knows it is safe to grant access to the room.
