hey guys what's up Billy cardigan here
as you know I was recently diagnosed
with sleep apnea and I was prescribed
this CPAP machine which is really great
to the mass that provides me a
continuous positive airway pressure is
like sleep really hopefully to sleep
cuts out the storm however my insurance
company has promised that they will take
my machine from me if I don't use it
enough I brought in an expert
Edmund winter who's going to show me how
I can help to keep the Machine yes let
me see this
so this is the Philips Respironics
dream station and as you can see right
here this one actually has a cellular
modem in it why would they need that so
they use the cellular modem so that your
insurance company can monitor your sleep
data so I'm actually gonna destroy this
for you right now okay
great so now that we have that out of
the way we can look at the SD card and
that's where it's actually storing the
data your insurance company might
request this every three to six months
right to see that you're using the CPAP
machine I can show you really quick how
you can at home modify this data and add
new entries so that your insurance
company will never know your personal
private sleep data very cool well I'd
love to see how that works okay I'm
gonna put an SD card so what we're gonna
want to do is gonna look you see that
two zero three six four three three one
directory right so that we're gonna want
to go into that directory and then we're
gonna want to go to the p0 folder okay
we look here that's all of your sleep
data okay and that includes the summary
data and the waveforms so what we're
gonna want to do is we're gonna take say
last night's sleep entry and let's
modify it so that your insurance company
doesn't know
what date you you were using the CPAP
machine okay so I'm using the DX utility
but there are lots of good hex editors
out there if you prefer you know GUI
application that might be easier for you
to use whichever you prefer so I'm just
gonna open this file up and after some
header information we right here that's
the start of the timestamp where it's
recording the time that you slept so I'm
just gonna modify this so that it looks
like this was from tomorrow instead of
last night so I'll just change this to
say 7 a 2 0 0 0 0 1 yeah great and now
all I have to do is just modify the
checksum at the end which verifies that
the file is still valid and hasn't been
altered or corrupted in any way so I've
already calculated this but it's easy
enough to calculate this at home if
you're modifying your own files on the
system so here so we just need to make
this a 3 3 3 4 D a d-10
and that's all there is to it so I'm
just gonna save this file and you're
done Wow that's a very cool sick and
easy way to modify the data from your
CPAP machine so these tips and hints
have been very helpful and it's an easy
way that anyone could just do it at home
so Edgar thanks for coming on the show
my pleasure thank you
