From YouTube: Bringing Trustworthiness in Industrial Device Lifecycle using Verifiable Credentials -Marquart Franz
Description
Bringing Trustworthiness in Industrial Device Lifecycle using Verifiable Credentials - Marquart Franz & Saad Bin Shams, Siemens AG
An industrial device goes through many phases in its lifecycle. Its life begins with the manufacturing phase, after which it is transported to the customer where it is onboarded and then the operational phase starts. It can then continue on functioning before it is sold to a new owner or offboarded and perhaps also replaced. The proliferation of industrial IoT devices brings in more challenges for the operational technology. Customer site should be able to go through industrial device lifecycles from multiple vendors with as much ease as possible. In this talk the presenters explain how verifiable credentials can potentially help us in achieving a trustworthy and automated approach in cycling thorough the different device phases. With the help of demo that showcases prototype industrial devices approach using verifiable credentials for German Railway operator (Deutsche Bahn), the presenters will discuss the current tools available and dive into some of their shortcomings in the context of devices. This presentation also aims to bring forward the pertinent discussion of the disconnect in the world of devices and the web technology.

A
Good
afternoon,
from
my
side,
see
you
all
here,
late
afternoon
last
session
before
drinks
or
whatever
we
get.
Let's
see,
hopefully
something
interesting.
My
name
is
Margaret
Franz
I'm
from
Siemens
technology,
which
is
the
central
r
d
inside
Siemens.
My
colleague
wasn't
able
to
join
because
of
reason
problems
not
arrives
in
time.
He
sent
his
regards
I
I
assume
he
will
be
watching
virtually
nice
art,
thanks
for
having
me
I
want
to
cover
industrial
world
and
industrial
World
connected
to
these
New
Kids
on
the
Block
blockchains
and
identities,
especially
self-solving
identities.
A
I'll,
assume
that
you
know
what
who
Siemens
is
large
german-based,
International
Company
180
years,
some
hundred
thousand
employees
and
so
on,
and
you
can
look
it
up.
I
will
not
go
to
in
the
details
or
Arias
details,
we'll
more
cover
how
we
use
it,
why
we
use
it
and
what
it
make
the
benefit
in
the
industrial
world.
So
we
are
part
of
the
project.
Id
Union,
it's
a
German,
funded
project.
A
I'll,
when
you
looked
up
the
my
presentation
from
last
hyperledger,
a
global
forum,
you
will
see
an
introduction.
I
will
only
cover
parts
of
this
here
and
we
target
a
natural
person,
legal
entities
and
things
and
the
things
not
the
one
side
of
the
things,
the
hard
side
of
the
things
all
the
industrial
things.
So
for
my
reunion,
we
managed
since
last
year
to
bring
up
our
first
really
major
Milestone,
which
is
establishment
of
the
non-profit
European
cooperative.
A
The
other
is
we're
working
with
different
other
projects
in
a
consortia
and
other
being
active
like
here
in
joining
the
European
identity,
wallet
Consortium
that
where
our
Focus
or
one
of
our
focuses,
is
the
organizational
digital
identity.
So
they
are
natural
persons,
legal
entities
here,
organizations
and
things.
So
for
more
use
cases.
We
cover
broad
range,
a
lot
of
use
cases
using
our
test
Nets,
as
mentioned,
and
for
this
talk
it's
about
industry
and
iot,
and
there
you
see
Master
data
management,
I
think
for
the
I,
should
laser
pointer.
A
So
that's
better
for
the
people
online,
so
industriality.
What
is
industry
legal
entities
are
working
together,
the
supply
chains
buying
and
at
the
end
somewhere.
In
the
end,
we
are
the
end
customers,
As
Natural
person,
because
we
buy
it
and
have
to
pay
all
this,
and
we
all
know
that
a
lot
buzzwords
like
iot's
and
blockchain
you
always
have
to
know.
What
does
it
mean
and
looking
at
something
like
iot
is
mostly
a
kind
of
edge
device
and
an
edge
device
for
me
is
processing
information
near
physical.
A
Devices
which
do
the
work
which
generate
the
money
at
the
end
of
the
day,
it's
called
OT
operational
technology
and
the
iot
is
a
new
kit
on
the
Block,
helping
the
OT,
generating
money,
making
more
efficient
and
more
insights
and
so
on.
You
all
might
be
Familiar
of
this,
but
you
have
to
understand
that
there
are
a
lot
of
parties
working.
A
lot
of
supplier
have
to
be
in
the
factory
or
in
other
machineries,
bring
together
the
result,
so
they
come
together.
Work
together
and
the
systems
are
special
configured,
have
special
communication
and
so
on.
A
A
A
So
it's
easier
when
you're
in
a
newer
plant,
we
already
collect
a
lot
of
data
where
we
can
do
all
the
things
and
connect,
and
you
know
how
to
do
it,
but
Industries.
Also,
there's,
invest
and
invest,
has
to
generate
money
and
not
cost
every
day,
more
money
so
and
there's
life
cycle
and
the
life
cycle
in
Industry.
A
If
you
have
an
energy
plant
or
you
have
a
train
or
even
you
own,
a
car,
you
know
it
hopefully
runs
for
10
plus
years
or
so
yeah
so
and
I.T
always
moves
in
a
speed
of
a
light
compared
to
Industry
development
and
and
operations.
So
here
you
have
a
lot
of
challenges
and
which
we
have
to
deal
yeah
like
concept
at
iot
connecting
to
the
OT,
gets
the
data
outer
and
do
something
useful,
I'm
gonna,
add
value,
but
the
long
Liberty
has
to
be
somehow
secured.
A
Then,
since
the
connection
came
into
every
device,
what
does
it
mean?
How
to
secure
how
to
update
solar
benefits
came
with
some
drawbacks,
yeah
there's
connectivity
and
you
have
to
manage
how
to
do
this.
Normally
you
just
Shield
your
device
that
nobody
goes
out,
but
something
has
to
let
out,
especially
when
you
have
to
generate
new
data
and
has
to
be
shared
yeah
how
to
do
this,
how
to
bring
this
out
yeah
so
up,
patches,
updates,
lifecycle
and
Implement,
and
then
this
new
legal
requirements.
A
You
have
to
somehow
find
your
way
around
this,
for
instance,
for
patching.
The
small
footprint
is
about
the
Civil
infrastructure
platform,
which
we
funded
in
together
with
other
partners.
2016
about
do
Linux
kernel
support
for
more
than
10
years,
because
when
you
take
classical
desktop
linuxs,
you
get
for
three
to
five
years
yeah.
So
that's
you
have
to
do
and
let's
go
to
early
Union
and
those
industrial
use
cases.
A
So
the
middle
pillai
I
addressed
at
the
beginning
and
the
good
and
the
bad
part
is
the
devices
evolve,
get
more
smart
and
iot
is
just
a
smart
device
and
smart
is
just
a
computer
in
the
device,
but
smart
also
means
more
flexible
computation,
not
the
classical
OT,
designed
to
the
spot
to
the
price
point,
which
only
does
what
it
is
used
to
yeah.
So
it
must
be
a
little
bit
more
or
you
have
this
industrial
edges
which
does
bring
new
computers
in
close
to
the
machine
and
communicate
with
the
machine
yeah.
A
So
the
devices
have
evolved
from
getting
the
information
about
the
asset,
the
device
being
more
passive
yeah
you
have
a
plate
on
it.
The
nameplate,
which
gets
more
digital,
gets
the
information
from
this
plate
and
in
Industry
4.0.
The
digital
twin
of
the
device
is
called
asset
Administration
shell,
which
holds
the
information
of
the
device
that
someone
who
needs
it
can
ask
about
the
device
and
really
managed,
and
this
admin
relation
shell.
A
Can
we
it's
it's
described
in
a
file?
How,
in
the
when
you
have
the
static
version,
how
you
use
it
yeah
and
when
you
add
now
our
wonderful,
verifiable
credentials,
then
you
can
do
a
lot
more
about
because
what
which
device
and
how
you
work
with
it.
So
we
introduced
verify
the
Dentures
together
two
devices
and
the
digital
twin,
and
when
you
go
to
Industry
Fallout,
oh
you
see
the
value
chain
which
is
more
or
less
produced.
A
A
Will
the
provider
of
the
machine
will
give
you
the
information
and
because
you
see
something
could
be
approved
when
this
component
behaves
different
and
the
use
case
was,
could
we
have
new
business
models
with
collaborative
condition,
monitoring
of
the
component
in
a
machine?
And
then
you
get
to
the
problem
that
do
you
know
the
component
supplier
in
the
machine
with
the
main
effect
machine
manufacturer,
give
you
the
information
about
his
supplier,
and
this
is
a
data
sharing
which
makes
a
little
bit
the
world
different.
A
A
A
So
so
getting
the
information
is
whether
it's
you
as
a
customer
or
supplier,
a
lot
of
information
you
get
from
the
website,
product
information
and
then
you
normally
asked
I
need
more
hardness
of
the
information.
Show
me
please
some
credential
proofs
and
so
on,
and
how
and
when
you
still
have
the
okay?
Yes,
you
told
me
you
are
certified
by
abce,
and
can
you
check
it
or
do
you
just
believe
it
today's
you
just
believe
it.
What
was
verifiable?
A
A
So
if
you
had
this
triangle
with
down
to
the
component
supplier,
where
these
small
little
colored
icons
are
asset,
Administration
shells,
so
little
twin
of
the
device,
you
could
do
this.
When
you
say
okay,
I,
have
a
connection
in
the
digital
twin
of
information
or
in
the
device,
is
information
about
the
manufacturer
or
the
components
about
the
manufacturer
that
he
can,
that
you
have
an
opportunity
to
connect
to
him
and
do
what
the
use
cases.
A
So,
when
you
take
organizational
identities,
yeah
and
you
introduce
these
wallets
for
the
companies
and
the
identities
come
for
companies,
and
you
have
the
you
can
work
on
that.
The
component
in
the
machine
in
the
by
the
operator
as
a
credential
from
the
component
supplier,
which
is
in
the
machine
at
the
beginning
else.
A
You
wouldn't
see,
what's
in
the
machine
so
and
how
you
could
approach
this
and
what
I've
done
in
idle
Union
is
okay,
we
have
first
have
to
have
organizational
identities,
and
when
you
have
organizational
identities,
you
can
do
things
like
connects
the
com,
the
customer
supplier.
So
this
is
a
classical
peer-to-peer
and
have
another
corporate
buyer
presenting
the
credential
he
gets
from
his
company
and
connect
to
the
supplier
and
the
supplier
can
say:
okay,
I
know
no
you're.
A
A
corporate
buyer
I
know
your
company,
because
it's
in
the
credential
I
can
ask
for
the
public
bid,
because
it's
in
get
more
information
and
vice
versa.
That's
the
customer
can
ask
okay.
At
the
end
of
the
day,
you
will
send
me
in
an
invoice
and
I
have
to
pay,
so
I
have
to
do
everything
to
do
to
check
what
I
have
to
do
when
I,
when
I
want
to
onboard
you
at
the
beginning,
getting
a
lot
of
information
bank
account
and
so
on,
and
this
we
used
in
this
setup.
A
A
A
And
here
you
have
now
an
automated
way
to
get
all
this
information
to
say:
okay
and
I
know
new
the
customer
knows
the
supplier
supplier
knows
a
customer
and
can
check
how
the
relation
is
between
the
bank
account
and
the
organization
yeah
or
the
vet
number
or
the
global
location
number,
and
it's
something
more
than
just
nowadays
a
lot
of
filling
out
Excel
sheets
or
printing
out
something
having
a
PDF,
and
this
can
be
automated.
What
we
have
shown
in
this
interop
plug
Fest.
A
This
company
came
out
together,
supplied
this,
and
so
the
the
largest
demo
was
a
B2B
online
checkout
clicking
and
by
clicking
the
QR
code
it
connects
to
the
supplier.
The
supplier
asks
the
company
of
the
purchaser
and
back
and
forth,
and
then,
when
you
say,
okay,
I
have
I
have
all
the
information
I
need
to
do.
The
business
I
can
put
it
to
my
internal
it,
which
we
all
have
to
say.
A
Yes,
it
will
be
shipped
to
you
yeah,
because
I
know
know
how
to
send
the
invoice
for
and-
and
you
know,
which
you're
dealing
and
all
your
other
requirements
you
have
for
making
business
with
me
is
okay,
so
we
have
the
organizational
part.
Then
it's
about
humans,
how
to
connect,
and
as
I
said,
this
is
as
an
Administration
shell
as
student
to
Twin,
which
you
can
look
in.
A
A
Id
connect
server
and
the
cas
and
so
on,
but
if
you
add
the
credential
of
an
employee
of
your
of
a
customer
yeah
who
can
connect
there
or
for
the
manufacturer
that
you
don't
don't
allow
just
whole
Siemens
to
connect
to
the
machine,
but
someone
who
can
prove
that
he
is
from
zemans
and
only
these
five
or
20
people
yeah.
So
just
do
the
magic
with
accessing
this.
A
A
So
this
would
be
the
human
part
which
is
going
in
and
then
the
next
thing
was:
what
do
we
do
when
we
know
the
new
one
part?
But
the
industrial
part
is
a
little
bit
more
difficult
yeah,
because
the
devices
are
shielded,
they
said
our
environment.
They
can't
just
watch
as
a
QR
code
for
initiate
connection.
A
A
A
Okay,
let's
do
this
on
a
real
device
on
a
real
big
long
device,
which
has
a
lot
of
components
in
it,
get
to
the
information
and
because
Deutsche
Bahn
operating
these
devices
I
said
okay,
when
I
could
have
this.
What
could
I
do?
Yeah
I
know
that
this
device
is
really
from
the
manufacturer's
image
or
whatever,
and
because
I
can
ask
the
device
yeah.
A
So
it's
not
effectivise,
and
there
was
some
fraud
in
between
it's
really
I
can
ask
it,
so
it
only
would
they
would
have
to
have
the
the
key
material
to
bring
it
in
that
our
device
is,
is
really
100,
faked,
yeah.
So
a
lot
more,
you
find
a
lot
of
rebuild
devices
out
there
in
the
market,
and
this
would
be
an
approached
when
all
the
other
supplier
also
align
on
this-
that
you
can
have
okay.
A
A
So,
starting
with
yes,
we
exchange
at
the
beginning,
our
identities
between
supplier
and,
like
I,
showed,
and
the
customer
checking
this
with
your
internal
ID
and
everything's
in
the
additional
information
is.
We
now
have
the
did,
did
informations
or
the
date
document,
and
all
this
and
know
how
how
we
can
connect
to
this,
and
then
he
buys
Deutsche
Bond
bison
machine
from
us.
A
component
right
yeah.
So
in
the
component
already
is
technology
which
is
in
the
described
in
the
paper
it's
to
make
it
small.
A
A
So
and
then
lodger
Bond
would
say:
okay,
I
bought
the
device.
Now
I
want
to
be
the
owner
device.
Said:
okay,
I,
don't
know
you
I
only
you
know
of
my
current
owner,
so
it
will
ask
us:
okay,
is
this?
Okay,
we'll
we
will
say?
Okay,
yes,
we
know,
or
or
paper
or
I.T
says
you
have
bought
it.
Yes,
please
check
whether
Deutsche
Bond
can
talk
to
you
the
credential
way
and
take
a
new
credential
and
put
in
the
new
owner.
A
So
this
was
then
we're
going
a
step
down
or
will
we
delete?
It
has
to
be
implemented
in
the
way
that
there's
no
a
new
owner
of
the
device-
and
this
is
ownership-
comes
at
now.
You
can
do
a
lot.
More
example
was
maintenance,
so
the
maintenance
company,
which
does
the
maintenance
at
the
devices
now
can
get
a
potential
that
they
allowed
and
to
stay
to
do
this
or
that
to
that
device
or
this
region
of
devices
and
so
on,
and
you
can
have
this
at
your
door
or
your
plant
will
be
opened.
A
You
can
go
in
if
you
can
prove
or
you
come
to
the
device.
They
all
will
ask
you
who
are
you
I
will
not
open
the
door
and
you
all
will
not
open
the
screen
for
the
engineering
or
changing
engineering
part
parameter.
But
if
you
show
me
a
credential
by
signed
by
my
owner,
then
I
open
up
the
screen
and
you
can
change
the
engineering
parameter,
also
yeah
and
then
at
the
end
the
maintenance
partner
should
issue
a
credential.
What
is
has
happened.
A
I
currently
write
down
a
lot,
so
you
can
collect
all
this
over
time
to
have
this
audit
trail
of
information
of
your
device,
so
your
little
returnably
enriched
and
whether
it's
in
the
device
or
it's
connected
to
device
and
runs
nearby
or
in
the
clouds.
It's
implementation
detail
how
you
do
this,
and
so
this
was
a
proof
of
concept
with
this
country
done
and
it
was
done
on
real
devices
yeah,
so
they
have
a
Advanced
train
lap.
This
is
a
a
train,
an
old
ICE
train
which
is
allowed
to
drive
yeah.
A
A
We
have
done
this
here.
We
showed
this
last
year
at
the
degree
convention
and
the
week
before
last
week,
driving
around
and
in
Berlin
and
show
this
to
the
public
and
the
press,
and
so
on,
presenting
or
two
use
cases.
The
one
I
just
showed
you
or
there's
an
asset,
identity
and
tracking,
and
the
other
use
case
was
replacing
the
backboard
blocks
by
a
blockchain
which
is
distributed
over
the
train,
a
local
blockchain
yeah,
so
that
you
only
not
only
have
one
directly
recorder.
A
You
could
copy
it
out,
and
although
we
tested
this
with
real
access
to
the
bus
system,
so
the
old
one
as
an
mvv
bus,
the
newer
one
have
profibus
where
you
get
the
information
which
is
currently
recorded,
and
you
can
record
more
the
information
that
the
current
recorder
records
and
the
recurrent
recorder,
which
was
the
one
here
down
here,
is
a
harsh
environment
device.
But
in
future
system
architectures
you
will
have
more
and
more
computing
power,
like
all
Nixons
and
so
on.
A
They're
working
on
that
you
can
say:
okay,
if
I
have
space
I
can
just
put
it
in
and
collect
the
information
and
because
of
a
lot
of
suppliers
which
go
in
such
a
device,
yeah,
the
big
one
yeah.
Now
you
have
one
piece
of
Truth
where
you
say:
okay,
I
know
what
has
happened
there,
because
the
recording
has
done
so.
A
This
was
a
summary
of
hyperledger
in
the
end.
Blockchain
on
track
is
on
track
was
on
track,
runs
on
tracks
because
you
see
the
next
stop
will
be
the
next
week
and
all
the
week
after
at
inner
transfer
the
big
fair
in
Berlin,
where
the
train
will
run
again
and
these
two
use
cases
I
showed
you
will
be
there
and
the
other
is
a
reunion
working
on
this
stuff.
We
have
from
tax
office
to
Health
Care.
A
A
Is
it's
doable,
so
the
Raspberry
Pi's
power
would
be
enough
yeah
depending
on
so
it's
it's
about
how
new
devices
has
to
be
developed
and
how
much
resources
you
will
have
in
there
yeah
for
industrial
companies.
You
have
now
a
new
option
to
secure
information
to
do
business
and
select
Which
business.
You
want
to
share
or
have
to
share
on
this
way
throughout
the
value
chain
and
throughout
the
value
chain.
A
Tomorrow,
Andreas
Kent
will
give
this
more
information
about
doing
this
for
CO2
information
of
devices,
because
you
have
to
all
collect
these.
Have
your
bomb
list
find
out
which
CO2
footprint
your
component
really
has
to
give
it
to
the
next
customer
which
needed
for
the
next
customer
in
the
supply
chain?
Have
a
look
there
and
I
think
we
have
seven
minutes
for
question,
because
thank
you
for
your
attention.
A
This
was
one
Deep
dive
or
no
I
was
a
high
level
flying.
You
were
not
down
to
crypto
and
not
off
of
the
bus
system
of
industrial
stuff
yeah,
but
the
main
message
is
iot
and
Industrial.
Iot
are
totally
different
things
because,
on
the
one
side
is
when
your
next
flip
doesn't
run,
how
much
money
does
we're
talking
about
and
get
you
something
like
when
the
factory
can't
produce?
A
We
will
be
in
a
big
trouble
when
we
are
one
of
the
supplier
yeah
so
because
it
generates
money,
a
lot
of
money
and
it
has
to
and
it's
got
yeah,
but
this
is
with
the
life
cycle.
You
have
to
solve
all
these
challenges.
I
brought
up
a
little
bit
different
life
and
the
magic
is
how
to
survive.
Cit
life
cycle.
A
Well,
that's
a
verifiable
credential
and
it's
the
system
which
we
set
up
was
there's
already
an
invitation
Link
in
the
device
that
he
can
connect
to
us
yeah.
So
the
these
they
have
to
overcome
this
first
connection,
yeah
how
you
get
the
device
which
is
somewhere
in
the
world
will
be
switched
on
and
the
owner
can
decide
whether
it's
allowed
in
the
onboarding
phase
to
go
to
the
Internet
yeah
or
use
it,
and
it
would
be
like
the
old
device
using
yeah
or
with
the
new
stuff.
A
At
the
end
of
the
day,
when
we
read
of
industrial
and
read
of
speak
of
devices,
we
speed
of
massive
scale
yeah,
it's
not
just
seven
billion
people
and
all
the
classical
customer
iot
devices.
There
are
a
lot
of
devices
yeah
and
you
will
not
cover
this
with
connecting
this
to
the
letter,
especially
not
when
it's
not
allowed,
because
it's
it's
sealed
environments
yeah.
So
how
to
to
manage
this
yeah
so.
A
A
Here,
if
you
go
more
to
caching
that
you
have
the
information
regularly,
updated
or
so
yeah
that
you
can
do
this
to
say
how
much
of
the
existing
areas
in
the
setup
you
want
to
have
how
to
connect
there
and
how
much
do
you
want
to
do?
Okay,
I
only
have
partly
because
my
owner
will
not
change
his
did
yeah
and
how
is
the
connection
to
the
other
devices
might
be
from
other
manufacturer
yeah.
A
So
I
don't
want
to
know
that
the
other
device
from
other
manufacturer
I
just
want
to
know
if
the
ownership
of
the
other
device
and
I'm
my
device
I
have
this
now
the
new
OC
same
owner
and
then
they're
allowed
to
talk
yeah,
so
it's
only
the
the
owner
and
more
the
device
doesn't
have
to
know,
but
the
device
don't
have
an
own.
Will
you
have
to
program
the
will?
What
is
allowed
to
do
yeah?
A
This
is
or
a
policy
or
whatever
you
call
it,
because
it
doesn't,
it
will
not
take
out
the
mobile
phone
and
point
to
a
QR
code.
Yeah
everything
what's
happening,
you
have
to
be
in
there
or
it
can
be
added,
and
here
the
owner
can
add
everything,
but
the
interpretation
of
what
is
added
has
to
be
programmed
I.
Think
the
second
question.
A
This
this
is
industry
for
the
low
yeah.
You
can
go
to
Japan.
Also
it's
it's
come.
You
don't
have
to
there's
just
one
digital
twin
approach,
yeah,
so
in
manufacturing
industry
as
an
Administration,
shell
can
be
used,
but
you
can
use
it
also
without
any
asset.
Administration
shells
yeah
it's
just
about.
Where
do
you
have
and
hold
this
information.
A
A
Oh,
is
it
here
on
the
on
on
the
now
here
on
the
bottom,
this
slim
relationship
Explorer.
Here
this
is
a
piece
of
software.
It's
open
source,
there's
a
lot
of
links
in
the
footnotes
where
you
can
look
it
up
and
the
out
of
Industry
followed.
Oh
the
industrial,
the
twin
organization
was
built,
Association
was
built
and
there
you
can.
You
find,
there's
one
link
for
the
video
for
accessing
here
with
you
with
the
credential
of
the
email
to
a
running
Administration
shell
Explorer
yeah.
A
B
A
So
this
is
a
glyph
came
out
of
the
financial
industry
because
of
Fraud
and
so
on.
And
yes,
like
I
mentioned,
with
the
use
case
for
organizational
IDs,
where
how
much
organizational
ideas
can
you
get
for?
Who
has
what
and
what
we
are
striving
is
at
the
end.
There
must
be
interability
of
these
also
in
in
the
first
slide,
I
had
with
the
European
Union
organization
ID,
which
will
come
out
the
Ides
too
regulation,
but
it's
International,
Company,
there's,
Europe
and
there's
the
world
you
have.
What
is
the
right
approach?
A
How
much
much
letters
in
these
do
you
need
to
worldwide,
at
least
three
or
so
Japan,
America's,
Europe
or
so,
and
how
will
the
life
is
working
on
this
verifiable
line
numbers
which
you'll
find
online
from
them,
which
now
they
use
carry
for
this
and
we
use
a
hyperledger
Indie
and
we
and
they
we're
working
with
them?
How
to
interrupt
so
as
well?
This
is
technology.
At
the
end
of
the
day.
Here
you
only
we're
working
on
an
identity
ecosystem.
A
This
means,
okay,
it
has
to
go
and
to
interrupt
first
with
these
99.99
Brownfield
out
this
out
there,
the
world
as
it
is
because
you
do
will
not
start
with
new
one.
It
has
to
fit
to
existing
like
this
or
oicd
stuff,
and
so
on
and
Clive,
which
Arc
IDE
you
need
depends
on
what
the
customer
believe
you
have
to
have.
It's
like
the
payment
in
the
shop.
A
A
Special
legal
entities
are
not
covered
with
all
the
registers
out
there,
although
we
have
in
our
project
also
the
German
business,
which
issues
the
100th
regista
Australia,
so
for
the
larger
companies.
But
then
we
have
the
transparency
registry,
but
what
is
the
redist?
Where
is
a
town
registered
or
a
doctor
and
so
on?
And
so
we
we
have
the
German
printing
ID
company.
We
have
all
banks
in
Germany
because
we
have
the
the
organization
thanks
for
like
and
finance
Cooper.
A
So
because,
and
last
year
the
regulation
of
the
German
ID
was
changed
and
the
anti-money
laundry
that
in
the
future
you
can
do
stuff
with
the
smart
Eid,
which
is
a
copy
of
your
German
physical
card
in
the
in
the
wallet
in
your
smartphone
yeah
and
there
it
starts.
When
you
have
this,
you
can
go
to
prokura
listed
in
some
registry
to
say,
okay.
This
is
really
the
company
and
and
then
so
therefore
start
with
the
human
setting
up
a
com,
a
company
because
Corporation
acts
throughout
humans
yeah.
C
C
A
So
what
we
all
need
is
one
base
layer
of
technology
which
can
work
together.
This
is
what
we're
working
on
yeah
and
whether
you
need
the
customer
will
ask
for
glyph
or
the
cost
for
a
d-trust
or
a
Target,
org
ID.
As
long
as
okay,
there's
credential
with
this
schemer,
and
you
believe
this
is
a
logger
deal
well,.
A
We
were
going
European
with
our
Corporation,
our
cooperative,
and
there
will
be
the
large-scale
pilot
next
year
for
wallets
and
we
are
a
part
of
the
Consortium
which
submitted
for
this
large-scale
pilot
and
there
you
see
all
the
the
different
member
states
which
are
in
this
consortia
yeah,
because
at
the
end
of
the
day
the
European
legislation
has
to
come
and
then
the
implementation
X
has
to
do
something.
So
for
the
European
level.
C
C
To
not
have
it
limited
to
a
German
project
and
and
development
abroad,
but
open
it
for
broader
audience,
so
the
cooperation
have
Compass
EU
member
states,
Norway,
Switzerland
and
UK.
So
everyone
in
this
realm
could
potentially
become
a
partner
of
the
European
European
three
company
members
now
and
we
are
planning
to
open
it
up
to
up
to
bigger
rounds.
C
A
You
have
to
check
the
details,
whether
it
makes
sense
for
you
or
not,
but
at
the
end
there
is
something
needed
how
to
bring
this
to
the
next
stage
yeah.
We
we
started
this
with
at
the
beginning
that
not
oh,
let's
do
a
three-year
research
project
having
fun
this
technology
and
then
put
it
in
the
drawer
and
put
it
in.
A
A
A
A
Who
can
act
on
behalf
of
a
company
yeah?
This
would
be
a
credential
for
the
CEOs
or
whatever
yeah
power
of
attorney,
and
the
other
is
what
I
had
in.
Was
it
the
use
case
here
that
you
have
not
he's
just
this
is
my
Siemens
badge.
It's
about
I
can
prove
that
I'm,
a
Siemens,
employee
and
I'm,
a
buyer
also
yeah,
so
our
out
of
the
the
supply
chain
Department
that
I
can
click
on
here.
A
A
A
You
could
have
a
lot
of
credentials
in
your
wallet
from
your
sports
club
to
your
company.
It's
just
another
relation
where
you
get
okay,
yes,
I'm
a
member
of
the
spotlight
but
I'm
an
employee
of
my
company
and
then
it's
dependent
on
what
should
be
in
there,
whether
it's
you
get
some
money
left
in
your
gym,
because
you're,
a
member
or
which
information
and
for
which
credential
you
want
to
use
and
you
get
from
your
company
yeah.
A
So
you
could
take
this
to
say:
okay,
I
now
have
the
information
and
or
I
have
several
credentials
for
my
employee.
For
my
company
to
say,
okay,
one
batch
is
one
credential
is
just
for
entering
the
compound
or
so
yeah
or
the
the
building.
The
other
is
for
special
credentials
for
these
buyers.
Whatever
you,
a
large
corporation,
is
consists
of
a
lot
of
companies.
Yeah
like
when
I
mentioned
here.
A
When
you
look
at
this
there's
remix
on
the
device
of
the
door
for
setting
up
this,
this
room
yeah,
this
is
Siemens
Building
Technology,
which
is
headed
in
Switzerland
yeah,
which
is
a
Siemens
part
as
well
as
humans
has.
Industry
demand
sales,
civil
infrastructures
and
Siemens
has
Mobility
yeah
so
that
the
train
stuff
and
so
on,
and
so
this
is
and
internationally
you
always
have
a
lot
of,
and
and
even
in
the
internal
money
flow.
A
And
when
you
look
in
what
your
treasury,
your
internal
system,
do
checks
throughout
the
different
parts
of
the
company,
you
can
automate
a
lot
and
yes,
this
is
all
done,
because
fraud
is
here,
yeah,
look
how
ABP
has
lost
a
lot
of
money
for
the
finance
guy
in
in
Asia
and
so
on,
yeah.
So
this
the
invoice
coming
in
and
the
checks
on
do
I
really
pay
it.
A
When
this
would
be
in
place,
I
think
it's
a
beginning,
you
could
do
a
I
think
eighty
percent
of
the
fraud
with
Corona
wasn't
doable
yeah
because
you
can
say
okay,
this
was
a
company,
and
this
is
a
bank
account
of
the
company
yeah
a
lot.
What
you
can
check,
yeah,
okay,
there
will
be
others
who
will
try
to
find
out.
What's
the
flow
in
this
system.
Let's
see,
but
at
least
it
is
looks
like
it
will
be
a
lot
better
than
what
we
have
currently
and
that's
what's
all
about.
A
It
will
not
solve
hunger,
our
piece
or
whatever,
but
it's
a
good
from
my
point
of
