[Applause]
you all yeah so I noticed that the
population really uses when it comes
down to you know identity systems data
and problems and this mystery date you
know people who like Tristan existing
right so my goodness here today is also
to talk about our journey
Isis nation great Singapore going
through there's this whole idea of data
privacy importance from a government
perspective and from there basically
just what you want what we walk away
with is the lesson that make a friend
and launch a nationwide a solution or I
have the distance right and how you
preserve data privacy okay you can get
this across to the general politics
without that that is really a huge gap
right between what the developer have my
and West Rihanna right palm the kind of
thing that we speak about in conference
because just bring out the public and
expect people understand right we
thought that as that you share there's a
lot of Lassiter's on from doing such
solution right and basically we are also
aware that right now I don't think
there's a decentralized way of
representing our visual images right on
this centrally on rendering things right
and we have a solution for that and they
still acacia tax photos of you are the
more technically inclined so it would be
a story and a story started as the first
talk was about a hundred watt halogen
right and then
it helps driving the political the
Destiny to provide you with it and all
the questions starters like hey can we
watch in this right so horse man did you
I make out if I show you right what
exactly this open attack station of
instance these will be talking to you so
that you get understanding of where the
perspective comes from rights instead is
internet will go right to end this is
basically autocratic say it's really
simple so you have her JSON document as
today call itself right people side in
the hot dry email whatever right and
it's yeah and all that it's random in a
way that's familiar to people right you
don't have to use a special until you
don't want you could have one and
basically when document is structured in
a way that is it looks good and looks
familiar to you if you get it from your
university it's going to look like Young
University certificate because we do
support things like right watching you
get a set and they're just really cool
when you show people that you can have
to use insert and really just upon that
how we do annual data privacy and this
is something really cool that we want to
talk about later where I can obfuscate
something oh I couldn't change any data
often so I do this I can actually remove
data element but it doesn't affect the
half of the document so that I can
needle and verify this document game
without an issue reassuring this the
screen all right so I'm trying to keep
the tank
expect of this moles of that if you're
interested in the tank I swear I wish
feel free to ask me about it at the end
right so so that's pretty much what we
have right want it to be really simple
for citizens and even people in general
to use so Jeannie beginning like that
the shoe fits you know your site looks
like we've got changes and really you
just want to be validated
just to make sure that it that it's
really alignment on the business as well
as the technical that's our version one
and then that's where you realize that's
a big time right so you know about that
and yes when we launch version due to
actually pick up certain things right on
scaling it on low so the first one is
really just the proof concept and it's
not an offering our Polytechnic who just
came to us and say hey can we have our
chains on case I hostage get on the
blockchain right the other we know so
the issues here is that what is
certificate what is a certificate right
when you want the data to install
definitely not a good option and how do
you issue them so that these the sim
ability of the budget does not affect
you you know you have track seven you
have a few transactions
it's not gonna help you scare with
50,000 suits in a batch right so our
solution is really simple we put data we
hash it we can hash we take the
following put it into a weapon that does
the rendering as well as the checking of
the profits it does so by just
retouching through the document and then
checking against the spa contract on the
interior and basically that's duties
right one for issues days and one for
revoke status anyone can do that
right so in the data it looks like that
okay so there were we prescribe a first
few seamen because you think even what
certificate data looks like right so we
say hey goes oh well there must fit into
this schema and it goes there and then
basically we use a couple three -
actually - on the issuance of you know
top tens of thousands of certificates at
one go yeah we managed to do like tens
of thousand and a couple minutes no
problem there right and the only
information stuff is actually just a
maca root 64 character hash okay so
there's no information linked to oxides
right and basically the point claim this
is how our product look like and we may
be told off something you are ready for
market
let's watch this decision
so there were a few key assumptions
right share that point line right we
assume that we do what goes into a
certificate that's I true right later we
found that certificates are not access
education credentials right and
different people think of different
dates when you talk about education
credentials right and schools are
definitely not finding the default you
get one can go go they wanted to look
like the way they do and then they want
it structured to tables in very real
quick
my semester said that wasn't quite what
our data structure supports right so
there comes open solution one where they
fall they fall a consulting so this is
really good like a lot of schools got
together informally and then say hey we
are gonna form a consortium and you are
going to give us a product and say okay
sure why not
right and that point in time um the
challenge is this how do we go about
analyzing data but again allow
customization among a different school
how much how much data goes into the
documents are do I add just the name do
I have the ice packs in there do I have
a whole year in there I there are all
sort of things how do you customize the
looks of it this is the first time the
visual thing came about and how can we
ensure both issuances based upon the
identity of the issuer to a real island
right it is we work with students right
to this point basically we had the same
where we have that like this is just and
we paste it allows schools to do like a
complement to our repository to change
this
they stop and then they still use it to
the toggle the different stops right and
then from that we introduce the user
control data privacy which is so long I
show you we can be much of a signal line
all these values without affecting the
integrity of the sense right
and also we allow for additional data
such as like signatures such as like
images and also updates to go within the
data file so that people can customize
it right and we don't prescribe we have
a more flexible their schema in general
right and basically how we do with
identity it's really supported at point
time right basically we have ha all
right it's called registry not Jason and
it's big results to this the pseudonym
in this mechanism the student in this
step ISM and this student at the Louisa
issue a warning man down here that I
could not be awkward that no figure out
myself and that is their sixth you know
they to correct the address figure right
and it wasn't a negate all right and
display them that were few assumptions
resume right that's you know what this
school is pretty good has one of two
templates and you can put that all in
one place yeah and it's really easy to
say who can issue such a document and
who couldn't write Oh
later we figure even at a table that you
couldn't do that because um how private
training providers those are really
tricky tricky spaces right so that comes
up I should do what we look into
decentralization in general all right at
this point in time the media is not the
schools are all higher optimistic like
hey watch this and then they put
to the newspaper all right just like all
the object projects all right and this
is really scary so in love with Holly
let me see oh my god like this the
school what this is small Scoob and me
so what school decided to put you know
ten different times of salad this is
just from what school so how do parents
I don't even know how to do this we
spend a lot of time reading this and
basically a lot of this or we can't
questions like a pile it seriously
enough some of you yeah sure the White
House and people says I needed
stochastic one right so if you install
custom from hand signals going to get
customs ones yeah sure and then when we
recommendations this reaches different
standards around technical abilities and
then this is like oh this is distracting
additional could I approve stupidest
Rufus and this is the best right can you
improve my career is because my users
doing your energy tomorrow
yes sure all right so as my that skinny
between a big issue for us so the next
question that what the tackle was how
can we scale it all just sing about to
experience a few school how can we not
manage those who request I don't want to
see any one of those requests right and
basically which is what the temper
changes with our church right how do you
just specify how you like to do your
stylingg
blog coming to the
although I'd say hey you review all good
right we don't want to do that and also
automatically verify identities of
issuers who are in the registry because
this onei as much people rejected to 1x
distributed up without work like hey
everyone get it right because you really
need to be really need to verify each of
them and it's a lot of work in there
right so the country central blog
extract green which is one of the two
key components on our version 2 which is
to use tracing effects right to then
render a document from another site that
is not from all sides right basically
within the certificate in there once for
the song it specified the render me the
view of it from a specific URL
conforming to a certain rendering
specifications and it basically outside
this to just go over to that site
whoahhh a blank page in the iframe and
they still passed it up through post
message into that room and had a
framerate lot of visuals right basically
this is how it look like in the data we
have a template remember additional uses
a template key right now he has the URL
is a admitted
mcdermott I basically it disrupts the
browser to go to the year I'll throw in
the 10 throwing the entire check so I
should be able to result right if it's
following the standard so this is how it
looks like right so this is example the
document that you saw Justin and Missy
in religious
I trade minute because the specific
sauce that was or a demo record ovens in
style and passing the entices became
object data and that part is then
responsible for rendering out of you so
this way we will not have any more
progressed on your visuals because that
is the basic concept arcs right and the
next question said now we have developed
a vetoes how then do we do identity so
far as we were taking like hey we are
already using such mechanism is called
DNS right can we then use DNS to then
prove the identity of the issue so there
was pretty simple is just like the title
to you
you have a protocol and and say that I'm
monitoring maintenance that one and your
spots on track address that I'm issuing
from instead address and basically you
just have to match the one within the
document and your side you see and they
speak with that you can really just
forget about the list the wrong place of
like people that you know and then
basically just have this thing like we
should buy a psycho domain right all
bridges anything ends up so the moment
we roll out this we realized that there
were schools around the globe
what kind of watching us in fact there
was one school that after we launched it
it kind of made it and they posted news
up today then it was and then we laid
upon the it was that hey they are
and it was really nice for us at a
playing time million that hit people I
views again without telling us who
disappeared right so it's fine I will
just show you what six so the technology
underpinning offensive sexual and the
taxation which is the document format
and hydrology high rendering the
identity document structuring and all
those things so we are open sourcing
that food skills right now working on
the document Asians the sauce is all
open it's just conditions a
little all women plates attract tiny
things out there open sensitive is fully
open software documentation race and the
Arkham project at the Singapore
government is also working on Star Trek
trust and we are basically bringing this
technology into the tree ecosystems and
basically is just working on three
documents and I thought that we are also
looking into how we can't organize deeds
in general so in the tree in the tree
sector there's this thing called the
Bill of Lading
basically represents my ownership of
cards right and basically I became to
how to organize that thing and make it
recognize her international level so for
that projects but we are also working we
are working with our international
bodies like the US Secret in fact we
were the one who host on us in fact of
weeks ago
in China right so if you're interested
in any of this kind of project in terms
of documents notarized or documents or
either disease system for you to talk to
us right and basically that's all for us
and it's this is this documentation can
have a go at the demo on the slide
toggle ahead is URL article quick so we
are we are free to explore use cases and
if you have suggestions or feedback
please go ahead and contact me alright
thank you for questions so if anyone has
questions please go ahead
and pen solution
- shut up - five six right now
yeah but then again be kids so help -
it anything good over tax just use
whatever this missile force
[Music]
right is this the case then of your
right around zone
I had no money or sold anything right
thank you
[Applause]
you
