Abstract

A system for the broadcast of alert messages to selected groups of recipients and their communications devices of a plurality of different types and communicating through a plurality of different communications means. Recipient profiles or characteristics are received variously from databases, directories, and communications nodes accessible by the system. These sources are queried for the identification of selectable groups which are then presented to a dispatcher for choosing the recipients. The alert message is then provided to delivery means which employ a plurality of included means each of which is particularly configured to communicate the alert message to a corresponding target device type. A response handler module then receives responses from the target devices for later reporting.

9. The system according to claim 1 wherein at least one device type is capable of operating a client application for receiving the alert message from the delivery module, the client application being further for authenticating the alert message.

10. The system according to claim 9 further comprising a key server module for generating a new private key, a new public key corresponding to the private key, and a new message tag associated with the private key and public key, the key server further communicating the private key and the message tag to the dispatch module, the dispatch module being further for encrypting a portion of the alert message based on the private key, the delivery module being further for receiving the message tag from the dispatch module and for communicating the message tag to the devices being of the at least one device type capable of operating the client application, the client application being further for querying the key server module based on the message tag for the public key corresponding to the private key and for decrypting the encrypted portion of the alert message based on the public key thereby authenticating the alert message.

11. The system according to claim 10 wherein the portion of the alert message includes a timestamp of the alert message.

12. The system according to claim 8 wherein at least one device type is capable of receiving voice messages, the alert message includes a text message, and the delivery module is further for converting the text message into an audio recording and communicating the audio recording to the devices of that device type.

13. The system according to claim 12 wherein at least one of the devices of the device type capable of receiving voice messages is a telephone, a cellular telephone, or a computer.

14. The system according to claim 1 further comprising a response handler for receiving respective acknowledgement messages from each of the devices, wherein the database is further for storing the respective acknowledgement messages.

15. The system according to claim 14 wherein at least one of the acknowledgement messages is an e-mail message, an SMS or MMS shortcode, a series of DTMF tones, or a voice-recognized command.

16. The system according to claim 14 wherein the dispatch module is further for establishing two-way communication with at least one of the devices from which the response handler has received a respective acknowledgement message.

17. The system according to claim 14 further comprising a reporting module for generating reports indicating a success or a failure of the communication of the message to at least one of the devices.

18. The system according to claim 1 wherein at least one of the devices accessible via the network access point is unassociated with the network access point.

21. The system according to claim 1 wherein communicating with the network access point to identify the devices accessible via that network access point comprises obtaining a list of MAC addresses, IP addresses, or hostnames accessible via that network access point.

19.
