Thursday November 16, 2016 plenary
of commissions of the honorable Senate of the
Argentinian republic
hall of the provinces
there I was about to do something that
time ago I find it incredible
I told the senators good afternoon
I would like to invite you to vote with this
electronic voting system that I
This time it develops for them
I clarify that I am not an illusionist magician but
what is going to happen I see it is that I’m going to
take the printed ballots with your votes
and I will be able to identify only by looking
the ones to whom each of you voted
at that moment in the living room there was
senators advisors and journalists
when I put on the bandage
I heard the bustle of the people
senators journalists talking
I heard the flashes of the cameras and
I grabbed a brutal vertigo had
prepared that meeting very much
that presentation had made the
system had thought how to explain it
I had practiced how to guess those
votes as the mechanism to guess it
however when I put on the band all
the situation became very real and I
I started asking how he had arrived
what do I do here
I got here and I guess a lot has
to see my doctorate in england
my work as conicet researcher
as a specialist in engineering
software thought
if these guys knew that when
I came to england I almost did not speak
English and that my first meeting with the
director department I did not understand anything
nothing
meanwhile the senators voted
I kept listening to the noise
cameras what happens and in certain
moment that seemed eternal to me
I was told
We finished to take the band now
I had to finish the demonstration
I had to guess those votes but
before I returned the votes to the
senators I told him that so be something weird
Please seriously
I told him that if there is not something in the paper
the printing ink
look well he added they found nothing
then I took the papers back
look at that vows and in a few minutes
unveils the mystery identify
exactly what printed ticket had
produced that senator I told you guys
they voted this after I explained how
I had done it
how easy it is how easy it is for
a printer add information in the
paper without us noticing
I explained that that voting system
electronic mail that I had already done in
reality
added a little bit of information and
they could not have realized
never country and then I will tell you
a little bit more about how that works
but in the end what did happen is
that the cheating printer already asked you
you know that most of the
commercial printers print about
small yellow dots that
Uniquely identify the printer
who printed that paper
our printers to yours the
mine the one we have at work
good part of these printers print
those little dots that if you do not see them
a blue filter can be seen if not
That day I explained to the
senators and they could live first
person
some of the dangers of voting
electronic in particular the simple thing that
was and that is to violate the secret of the vote
today still today despite what
specialists have said and explained
many media and politicians love us
convince that the only alternative
to the voting system that we have today
to the party ticket system is the
electronic vote as if there were no
the single paper ballot
they want to convince us of this they tell us
that faster more efficient than more
safe and reliable that the
fraud that runs out the rice the turn
the flight of tickets and I wonder if
Is it true that and the question you
will be that I propose that we
let’s ask if that will be true and
paradise
I’m going to propose an experiment in
this moment in this room has installed
a computer system connected to
high definition cameras that allows
read their facial expressions there in
the development system and manufactured by
experts therefore it is highly
trustworthy
this system is connected to the registry
national of the people for
Identification of your address
It also works even if you are using
glasses or contact lenses
how are we going to use this system of the
I will ask you to
all of you who give me your password
facebook they will see me
apple the volunteers are going to happen when
give me your facebook key I’m going to
do a live demonstration and
access your account
I will look at your personal data your
pleasures
everything you want basically a
bit
maybe even pole to with its walls or
can see your personal conversations
he could even see the conversations that
They deleted what we are going to do
is the next thing I ‘m going to ask for truth
rap that those who are willing to
give me your facebook key they close the
eyes now for a second
truths close those eyes that
they want to give me their facebook key
the system is processing the
results while you do it good
it happens that 98% of you
they just closed their eyes
thank you very much they are incredibly
participatory
now he is going to go a group of volunteers
network to withdraw all your keys good
before the volunteers go to
remove the keys and just so that
all of you be calm
I’m going to ask you now but for me
I’m going to ask you to raise your hand
those who have just closed their eyes
it’s 98 percent
raise your hand, all that is not the
98 percent to you clear the system
it’s not wrong in essence what it does not
does is what I told them I was doing
it can be because an error can be
because I made a mistake because the
audit made an error can be
because I was raped by the talent system
some programmer who works with me
he simply decided to violate the system
or there is always the solution
Hollywood who is a hacker in a
dark room lolo violated what
import
that the system was not working and if it was not
because we look again we do not
we would have known because we
we found out that he was not walking by hand
we all know how to vote with the
hands we do it since we are like that
to choose which party we are going to
choose which team we play for all
we know how to do that as we know how to do
we can understand it and how can we
understand what we can audit and also
we all see it as the responsibility of the
audit is distributed in all
saying this he asked them back with
honesty
if you know what happens inside
an electronic voting machine
the truth is that it happens in there where
the images of the
candidates in which the language of
programming that machine is made
communicates with other systems is
connected to the protocol network usa
probably the word that says neither
they even make sense for the great
most of you do but most
important thing that happens in there that
Ford and the software has this look
unless you are
ports in software made it is there
it is completely illegible no you
can you understand that
but the thing is worse none can be
of you can understand that
some sophos experts if they are going to
to be able to understand it
then what they will be able to understand
only a very small group of our
society
therefore we are delegating the
audit power over our
voting system to a small group
of citizens and not all
then there does not end the truth is
that we software experts
even if we could read the hundreds of
thousands of lines of code to make a
electronic voting system
we could never guarantee that
is free of vulnerabilities and this
it’s something that we know in computer science is
impossible mathematically guarantee
that the system is free of
vulnerabilities
therefore in the world the experts in
computer all we agreed there
global consensus that the use of
computer systems for voting is
an error
then the situation in which we are
in the next
we are delegating the power of audit
of our voting system in a
small group of people
the experts and this small group of
people tell us please do not be
this is understood
basically it ‘s like being up a
airplane have the pilot the door
screaming that please do not go up to
ip plane because it falls
we go up happily and we
we ask what will be faster you
flight will have a seat at first
another thing they tell us about the vote
electronic is that actually
the problem is when everything electronic
that if we can print the
ticket
then we are saved the company
of course he could see it I understand
it’s perfect now I’m going to propose
another experiment please review
check your tx credentials take them out
josito open them on that page
and tell me look at it tell me if you see something
I’m going to help him a little bit there
up in the x
Tell me if you see something weird and I ‘m going to
ask that if any of you see those
little white dots we have
there raise your hand shine of what
happened now is that I’m showing you
another use of steganography
basically these this technique is
try to hide information in full
view if you realize
they were all afternoon with that little dot
there and they never saw it
I knew but you do not
I suppose we suppose that you
they knew they said do it thoroughly and
third is the kid xabi prieto
little spots and the second part that
is what those little dots mean
there are also some dots and in this
moment you have the little dots
in that paper do not know if the dots
they mean they have documents that
ends in even number if the pulpits
they have to do with are male women and
lives in Palermo do not know I do know and
in fact those that have those dots
they have those names I knew all the
late the names of you all the
late only that you do not
So the truth is that seeing is not always
is to understand that there are many ways in
what a system can fool us
anyone who tells you that a system
audited is inviolable
in essence or do not know anything about software
is badly informed or
he is simply missing the truth
we know that of course
this is a moment in which any
reasonable person target or clear this
guy who is ahead is a subject
favorite decidedly hates the
technology does not want to use it and believes that
technology does not improve our life
well said is the opposite
live alive, let’s pretty much say
live of technology
I have all the devices that are
possible to have in their last
versions come here just happens
that technology has limits
raise your hand who is yours
they would go to their doctor and ask him to
make them deadly
some even those brave ones who
go to your doctor they ask you
mortals what they will receive as
answer the doctor and if he does not look no
Unfortunately I can not achieve
medicine has limits
technology also has limits
does not solve everything solves a lot
but not all
then that day in the Senate
I was blindfolded
but I realize that actually
I was trying to get the senators to
remove the blindfold
regarding the dangers of voting
electronic
that day the senators took the
blindfold and electronic vote
did not come out and today I want to ask
you are willing to take off
that blindfold
thank you very much
and
