The potential for unintended disclosure of the information.
Collection of metadata, and other things that fall in these categories.
Essentially, users are creating a lot of information, and
they should know what's done with it, and where it's going after it's created.
If we're talking about obscuring potential information flow.
That means that there's a possible way information can be shared, but
it's not made clear to the users how that's actually going to happen.
So here is an example of a Gmail account and though there's no messages in
the inbox, you can see that there's ads across the top.
People have been upset, and
there's actually been a lot of press over the fact that, these ads can be targeted
based on the content of the messages that you send and receive on gmail.
Google doesn't actually show anyone the content of your messages.
They automatically analyze them on their servers and
take ads where the advertisers have expressed key words, and
matched those to the things they've analyzed in your messages.
But people were very concerned that the content of their messages were
being shared with advertisers, it was just unclear what Google was doing on Gmail,
and that made a lot of people concerned.
When we're talking about obscuring actual information flow,
that means that information is being shared in a specific way, but
that's being hidden from the users.
Here's an example of that.
