I can understand that, and I agree that on some scenarios the confidentiality can be ignored. But I do think that is the case when the database actually holds confidential information like passwords. I would be happy for text saying that if database has no confidential information then confidentiality may be ignored, but if in most cases I think it does include confidential information and then it needs to be protected. Anyways I think this is to point the fact out to iesg, they can decide whether it is appropriate or not. Usually protocols have required confidentiality when there are tihngs like passwords to be protected. > The same reason applies to the definition in this document of > 'private elements'.

I am not sure if any real world requirement can be given, but I think the security considerations section should point out that the database has privacy related information stored in it and that should be taken in to consideration when deciding how the database is protected, and who has access to it. The privacy issue also brings up new topic, namely the lifetime of the data in the database. I do not know whether the entry stays in database only during the conference, or whether it stays there forever. For privacy information storing it long times can cause problems. -- kivinen@iki.fi
