and I'm here to present to you our
research project negotiation behaviors
between owners and bystanders over data
practices in Smart Homes I am thankful
grateful for such an amazing
group of caliber collaborators Eugene
Joseph and Jacob our students at the
classical mines and Dr Benjamin Gilbert
and Dr chuania are professors at the
Colorado School of Mines
and we are very excited to be presenting
at such a great conference today
why is perhaps important I realized that
I is not necessarily only about privacy
so I wanted to touch base about some
definitions and to build some come
common ground before we dig into the
details privacy is is simply the right
to keep your personal life private if
you choose to and information privacy is
the right to have some control and get
notified and asked to notice for any
data practices privacy is considered a
fundamental human right agreed upon by
the majority of the countries around the
globe and there are a lot of privacy
religious stations um such as gdpr
California Privacy Act and so on
privacy concerns are important to be
addressed because they might prevent or
delay growth in such an important
technology which is like the smart home
technology in general so if we address
the privacy concerns we might see some
growth and also perhaps smart home
devices have great utility we don't want
to lose that when we address the privacy
concerns so we have these kind of two
sides such as security and control and
convenience and entertainment who
doesn't like to say like hey Google hey
Alexa do uh this or play that I like to
do it certainly while I'm cooking or
cleaning
um there it's expected by 2024 we might
have 375 million smart home around the
globe and a home is occupied by more
than one person so uh
this number times two three four five in
some cases so it's the issue will be
relevant to a lot of people uh in the
near future
last slide about the definition I
promise uh owners are the main users of
the smart home devices bystander we have
two types of bystanders
um the type that can live with you in
this in the same home such as roommates
or spouses and kids and the type that
can be temporary in your smart home such
as family members friends and and
domestic workers data practices we talk
about how the data is collected shared
and stored and so on
um recent findings motivated us to
explore more uh in this research project
such as like honors and bystanders find
it awkward to talk about data practices
imagine if you go to your friend's home
and say like hey what devices do you
have and what data processes do you do
they might not know if they say like I
don't know that's a really legitimate
answer uh and they might be very honest
and owners are willing to address
privacy concerns but they have different
private preference so negotiating that
to a resolution might be a win-win
situation for both owners can preserve
the utility of their devices and based
on that can preserve uh the privacy of
their own data for example I can ask my
friend to not collect my facial data or
not to share it or to delete the data
after three days so we can reach
something in the middle
visually the problem by standards don't
have any control like regarding notice
consent or even like controlling their
data after that it's collected and we
wanted to explore the willingness which
we publish in pets last year and then we
want to explore the negotiation Behavior
which I am presenting to you today about
the question we ask is like what are the
negotiation behaviors and what are the
correlated factors about that and how
can we predict an outcome based on the
negotiation behaviors and the situation
factors
so the study design and recruitment um
we wanted to approach this problem from
a quantitative and qualitative
perspective because this is a new
problem a novel issue and this problem
space has not been explored sufficiently
so we didn't want to just want to do
that quantitatively so we went to Amazon
Mechanical jerk and we recruited a lot
of Tiff people 460. participant and we
balance that between best and the
participant and owner participant and
that is assigned by us we don't care
about if they own or not
own smart-time devices or not
factors which we consider when we
generate scenarios
to ask participants to go through is
between subject
relationship types such as friends or
strangers and negotiation types such as
like Circle collaborative within subject
will be like the device type which we
consider smart speaker and smart camera
and the three types of data practices
such as the data collection and storage
and sharing
uh we divided our study in three big
sections like the pre-negotiation kind
of questions then during negotiation
which when the participant is
interacting with our digital agent and
the post-negotiation
um every participant will be assigned a
role like they could be an owner or they
could be a bystander and if their own
owner if they are assigned to be an
owner in our study they will be
negotiating with a bystander bystander
digital agent and that agent could be
strict negotiator it could be a friend
or or a stranger or then they will
negotiate over the two devices under the
three different data practices
it will look like something like this so
we present the scenario to them then we
tell them what the owners disclose unto
them then we ask them how they feel then
this whole interaction will be like in a
chat bubble the blue bubble means like
the the participant responses and the
gray bubble as the digitalizing
responses
and they will reach a conclusion which
is like either an agreement or no
agreement and in this case for example
they reach an agreement about storing
the data for two weeks instead of like
six months or so and or or like forever
uh so I'm gonna report some of the
results I can cover everything the data
the paper has all the details so number
of rounds we found that the number of
runs are significantly different between
owners and owner participant and by
standard participant by solid
participant took less number of rounds
until they reach the conclusion either
with agreement or no agreement compared
to the owner participant we also report
the final prefaces of like what they
chose we provided four different
preferences for each devices and they
negotiate between those four preferences
so preference one will favor
um utility preserver
preservation and preference number four
will be good for privacy that means like
less utility more pricey for the
bystanders uh we notice which is
interesting in this uh in this slide or
even in the paper that by sending
participant kind of budged and agreed to
choose preference number one which is
like it favors utility because the power
imbalance because they don't own the
devices and that you might not feel they
have the right or entitled to negotiate
with owners of smart home devices while
the owner participant there's a variety
of preferences which shows like their
willingness to negotiate with the
bystander digital agent in our study
types of agreement I want to highlight
that full agreement mean that the the
participant reach an agreement and every
single negotiation interaction with our
digital agent
uh that means like six times uh for the
bystander participant they reach more
agreement when they negotiated with the
stranger as an owner compared to like
owner participant reached list agreement
with this with they negotiated with
strict by a stranger as a bystander
we also report the qualitative analysis
which is like if they reach an agreement
and budget or not budge and and what
they say uh from the open text responses
so in this case we we say like we're
we're reported when an owner
participants say like hey I'm not going
to reach an agreement and I'm not gonna
budge because this is my home and this
bystander is being ridiculous
um we also ask participant post
negotiation analysis like what is the
most important thing to negotiate about
an owner participant wanted to negotiate
about collection and storage because
it's easy so some uh one one owner
participant said like it is very clear
and cut I either collect or not that
means like they will turn off the device
so they don't collect anything
this due to like less technical or less
tech savvy
participant
um and might impact the utility
significantly by standard participant on
the other hand preferred sharing so they
might be okay with the collection and
the storage but they might not be okay
with sharing by owners
we also recommended uh uh uh
uh we provided some recommendations
negotiation Focus recommendation for
example more factor to negotiate about
and more price difference preferences to
negotiate about more factors mean that
they might negotiate the date the
location of the device so it's okay to
record in the living room but not in the
bedroom and so on and justify why we
choose this preference overall
negotiation means like hey if even if
you negotiate you can turn back the mode
to like the normal mode and we want also
we provided a recommendation to automate
the entire process between owners and
bystander in terms of negotiation
um and that is all and I'm happy to
answer any questions now
