This post-processing channel protocol is designed to filter (remove) specific parameters from the messages of any standard channel.
A channel with the parameters-filter protocol can apply to any standard channel to post-process its messages. That post-processing stage will remove message parameters listed in the parameters-filter channel configuration just before message registration in the original (standard) channel.
For example, such a configuration will unconditionally remove position information (latitude and longitude) from all messages:
ID of channel that received a message
ID of device that received a message
Name of device that received a message
ID of device type of device that received a message
Device unique identifier like serial number, IMEI, etc
IP:port from which device connecting to the channel
ID of protocol
Timestamp when server received a message
