Abstract: A method of verifying alerts received from alerting devices associated with a user. The method includes: verifying the received alerts from the user by applying a specified procedure to the user; analyzing the received alert in respect to specified temporal characteristics of the received alerts; classifying each received alert as either a false alarm or as a valid alarm according to the verifying and the analyzing; and reporting the valid alarms to a service center. Double checking the received alerts both by the verifying and the analyzing enhances alarm reliability.
