Jeff,
I understand your first example, which justifies the need for encrypted
only messages. However, I don't understand the second, which is :
2) I have a social worker who wants to provide confidential advise to
students and/or employees. Because of the sensitive nature of the
communications involved I want them to all be encrypted. Furthermore
I may want to have some "continuity" of conversation over several messages.
I can provide a communications infrastructure that hides the transport,
but I need the "privacy enhancement" technology to support this as well.
Why does the social worker require anonymity?
Regards,
Dan
