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 On 27 Sep 2013, at 19:21, Tony Crooks <[email protected]> wrote: > > On 27 Sep 2013, at 19:06, Ray Packham <[email protected]> wrote: > >> HI all >> for those worried Tabout privacy here is a set of fonts that apparently >> cannot be read by OCR , Ive not tested it but presume it will work for a >> limited period in conjunction with other tools, maybe ;-) > > > Of course, the NSA etc., would be looking at the machine codes not the > character images so not sure how private these fonts would be in practice. > Shades of people sitting in cars outside a building recording the EMF > radiation from a CRT monitor to get the codes, isn’t it? > > Regards, > > Tony > -- > Tony Crooks > ---------------------------------- > 53 Mendip Avenue • Eastbourne • BN23 8HP > Mob: 07428706227 > Tel: 01323-460789 > <mailto: [email protected]> > > > -- > You received this message because you are subscribed to the Google Groups > "Sussex Mac User Group" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send an email to [email protected]. > Visit this group at http://groups.google.com/group/smug. > For more options, visit https://groups.google.com/groups/opt_out. -- You received this message because you are subscribed to the Google Groups "Sussex Mac User Group" group.
