HI

That is true but it makes an amusing video to watch. The way we deal with 
secure traffic is to not put anything on the NET, its the only way.  I once 
worked on a Tempest proofing project for a Navy , stopping all EMF signals from 
exiting their building via CRT screens and also making their network secure, 
that was an interesting job, ahh the good old days when you knew who your 
enemies were, the Russians  and the Warsaw Pact  ;-)

Anyhow every file can have a hash that is unique and there are tables of hashes 
for images and documents etc, each file has its own header these headers again 
are readable and just one way that net traffic is scanned . There are other 
methods that GCHQ and other agencies use such as deep packet sniffing etc ( and 
I don't mean taking in the heady atmosphere of a Weeetabix box by the way , for 
those that don't know)  but I hope you get the general gist, hence my tongue in 
cheek comment 'maybe' as once the fonts are known its easy to beat.

Just think of numerous databases that email and internet traffic etc are all 
scanned and filtered against , the fonts  once known become breakable at some 
point...simples ;-)

Regards Ray
