The \textffm{Meow} protocol is a privacy driven instant messaging protocol.
|
||||
That protocol might be used for creating secure and distributed chat services or allowing machine to machine communication.
|
||||
This document describes the services provided by the protocol, the messaging structures and the transport protocols that might be used.

Using the \textffm{Meow} protocol a user won't be able to forward your contact information without your consent.

Each user knows you as a different identity, thus forwarding a known identity to another user is meaningless, any message to that identity signed by another user would be discarded.
