"
In that way, Prism helps justify specific, potentially personal searches.
But it's the broader operation on the Internet fiber optics cables that
actually captures the data, experts agree.
"I'm much more frightened and concerned about real-time monitoring on the
Internet backbone," said Wolf Ruzicka, CEO of EastBanc Technologies, a
Washington software company. "I cannot think of anything, outside of a face-
to-face conversation, that they could not have access to."
One unanswered question, according to a former technology executive at one
of the companies involved, is whether the government can use the data from
Prism to work backward.
For example, not every company archives instant message conversations, chat
room exchanges or videoconferences. But if Prism provided general details,
known as metadata, about when a user began chatting, could the government "
rewind" its copy of the global Internet stream, find the conversation and
replay it in full?
That would take enormous computing, storage and code-breaking power. It's
possible the NSA could use supercomputers to decrypt some transmissions, but
it's unlikely it would have the ability to do that in volume. In other
words, it would help to know what messages to zero in on.
Whether the government has that power and whether it uses Prism this way
remains a closely guarded secret." | h******t 发帖数: 872 | 2 This should be '863' project:
