As provided in the CALEA processes, no individual in the telephone networks may be aware that such a wiretap has been initiated.
• the network server may add an opaque marker to the call originating from the selected firearm.
• the opaque marker may allow the data to be associated with a particular device without disclosing the owner of the device or other data necessary to connect the individual user of the gun to the call.
• the network server may receive a call from the selected firearm.
• the selected firearm may call the network server according to the method described above with reference to FIG. 4.
• the firearm may have network connectivity and call a non-recording telephone device through the network server 1 14.
• the network server may continue the call and data transfer to the non- recording telephone device without transmitting a copy of the call and the associated data to the CALEA server.
• the network server may continue transmitting the call and the associated data to the other device without forwarding the call and the associated data to the CALEA server unless the call is marked for CALEA forwarding.
• the CALEA server may receive a copy of the data
• the CALEA server may simultaneously stream the information or forward the incoming call data to another device, such as a law enforcement personnel's mobile device through a telecommunication network.
• the CALEA server may decrypt the firearm data if the data is being transmitted in encrypted format.
• all firearm data transmission may be encrypted to prevent unauthorized parties from obtaining tracking data of the firearms.
• the CALEA server may have a decryption key to allow it to decrypt the data from the selected firearm or all firearms.
• the CALEA server may store the firearm data for later use or presentation.
• the CALEA server may store in a database any data received through its wireless wiretap of a firearm for use in investigations and subsequent criminal prosecutions.
• Portions of the embodiment methods may be accomplished in a CALEA server architecture with some of the processing occurring in a server, such as maintaining databases of normal operational behaviors.
