karl: different identities in different contexts
08:40:44 [jmorris]
.. marketing leads to interesting discussions about "privacy"
08:42:23 [jmorris]
.. communications can be global, instantaneous
08:42:38 [jmorris]
.. info is replicated on net -- much harder to lie
08:42:51 [hendry]
http://www.w3.org/2010/api-privacy-ws/papers/privacy-ws-3.html is Karl's pp btw
08:42:52 [jmorris]
.. info is permanent
08:43:53 [jmorris]
.. once you give access, you have no way to take it back -- to say "stop using my data"
08:43:59 [tlr]
umh
08:44:02 [tlr]

08:44:10 [jmorris]
.. how do we make it possible to have a loss of memory
08:45:16 [tlr]
http://www.w3.org/2010/api-privacy-ws/slides/dubost.pdf
08:45:37 [jmorris]
.. privacy is cultural
08:45:51 [jmorris]
.. people's privacy views differ than businesses

.. robots.txt is a bad protocol ... only works if you have access to root of site
08:47:06 [jmorris]
.. it shows what you want to hide
08:47:25 [jmorris]
.. can only do that with .htaccess
08:48:24 [jmorris]
.. Tumblr and other sites give you the ability to keep search engines from indexing personal site
08:48:56 [jmorris]
.. your site is public, but you give links to it (not reached through search engine)
08:49:18 [jmorris]
.. need something better that robots.txt
08:51:03 [jmorris]
.. browsers are my main communications tool

08:56:32 [jmorris]
John Carr: no slides
08:57:00 [jmorris]
.. works with range of orgs across europe concerned about childrens use of Internet
08:57:24 [jmorris]
.. in UK in March 2010 Ofcom did research in child use of social network space
08:57:55 [jmorris]
.. of 8-12 year olds, 19% had profiles on three social networks
08:58:12 [jmorris]
.. most had profiles private, but 11% did not
08:58:35 [jmorris]
.. looking at all children - 25% of all children on sites they should not be on
08:59:05 [jmorris]
.. not all parents monitor kids at all times
08:59:37 [jmorris]
.. this is environment into which new geolocation services are being dropped
08:59:59 [jmorris]
.. geolocation services specify 18 year old as minimum age
09:00:17 [jmorris]
.. but geoloc services can be lined to 13 year old social network page
09:00:51 [jmorris]
.. wants to enlist group's help to address problems
09:01:24 [jmorris]
.. almost think that age limits should be dropped, because they are not being enforced
09:01:43 [dsinger]
if, on the internet, no-one knows you're a dog, how do I 'know' you're a child?
09:02:35 [dsinger]
and is there a Streisand effect here, saying 'if you're young, DO NOT LOOK HERE!'? what do the young immediately wonder?
09:02:48 [Kangchan]
Kangchan has joined #privacy
09:02:54 [ifette]
especially given that in the US we are forcefully against any sort of national ID card that could actually be used to prove identity/age online
09:03:00 [jmorris]
.. sites purport to want to ban children, but they do not enforce
09:03:42 [jmorris]
.. asks what would an 8 year old's judgment be on what privacy means
09:03:55 [eisinger]
in germany, we're currently developing an id card that would allow you to prove (parts of your) identity to a website
09:03:58 [drogersuk]
+1 to ifette's point
09:03:58 [eisinger]
such as the age
09:04:16 [jmorris]
.. every country in world specifies 18 as minimum age to be adult
09:04:22 [ifette]
jochen - remind me not to move back to germany :)
09:04:32 [drogersuk]
also, as he said - the parents are actively encouraging the kids so they would just leave their card with the kid
09:04:46 [eisinger]
ha, i'll remind you end of september that you didn't want to come here
09:05:23 [jmorris]
.. hope that we can find a way in this technical space to find better technical tools to deliver broad social policy
09:06:08 [jmorris]
.. we all want privacy rules over out data, but if a company is dealing with physical whereabouts, this is very highly sensitive
09:06:19 [jmorris]

09:06:23 [MikeS]
q?
09:06:50 [jmorris]
.. in 2003 mobile services in UK started rolling out location,
09:07:03 [MikeS]
RRSAgent, make minutes
09:07:03 [RRSAgent]
I have made the request to generate http://www.w3.org/2010/07/12-privacy-minutes.html MikeS
09:07:07 [drogersuk]
on the child protection issue - most kids are abused by someone that is known to the family so they are likely to have given their location to that 'trusted' person
09:07:18 [jmorris]
.. companies accepted validity of location concern
09:07:31 [jmorris]
.. key thing they did is make location a paid-for service
09:07:54 [jmorris]
.. if you paid for it, there was an audit trail
09:08:06 [jmorris]
.. if you were trying to track a child, you had to do a further check
09:08:20 [jmorris]
.. postal checking process
09:08:27 [drogersuk]
there are use cases getting mixed up here - for example preventing kids accessing over 18 content is entirely different to 'child protection' in the traditional sense
09:08:35 [jmorris]
.. before you could commence tracking service on child
09:09:06 [fjh]
example, know where you are at 4pm every monday, can determine pattern
09:09:10 [jmorris]
.. does not see evidence of these checks in the new location services

09:10:02 [rbarnes]
hendry: depends a lot on the browser
09:10:03 [drogersuk]
@hendry - maybe we should ban the internet
09:10:07 [jmorris]
.. experience with ticking box -- gambling sites just asked to tick a box to gamble
09:10:36 [jmorris]
.. kids were developing gambling addiction
09:10:37 [hendry]
drogersuk: i think a child can survive without geolocation features
09:10:49 [jmorris]
.. law changed to require age verification system
09:10:54 [drogersuk]
@hendry - or the internet ;-)
09:11:02 [ifette]
Payment doesn't seem like any guarantee. I can go to any store in the US and buy a "pre-paid" credit card, and provide whatever name and address I want that will get associated with the card.
09:11:17 [jmorris]
.. since law has passed, children have not being able to invent identities
09:11:23 [drogersuk]
I remember this discussion about 0898 numbers in the early 1990's. Never stopped me
09:11:26 [hendry]
rbarnes: turning off geolocation needs to be really simple to do. simple enough for a parent/guardian
09:11:29 [jmorris]
.. easy for 18 year olds, much harder to do for younger
09:11:48 [rbarnes]
hendry: ... and permanent enough that the kid can't turn it back on?
09:11:53 [ifette]
hendry - turning it off isn't the hard part. It's ensuring that the kid, who is probably more savvy than the parent, can't turn it back on
09:12:28 [drogersuk]
@dsinger - yes I missed that too
09:13:03 [hendry]
ifette: true, but i struggle to toggle geolocation and i'm smart I think
09:13:11 [jmorris]
dan: what role do education, parents, etc. play in addressing this problem?
09:13:14 [drogersuk]
most of the people in this room started their technical careers getting round restrictions that were put on them as kids
09:13:31 [jmorris]
john carr: agree that education is part of it, but technical is also part
09:13:33 [hendry]
ifette: in chrome the option to turn off geolocation is buried under a couple of menus!
09:13:54 [ifette]
hendry, everything in chrome is buried under multiple menus because for most users there is no desire to turn this off permanently
09:14:04 [rbarnes]
hendry: i can't find the toggle in firefox; ironically, it's not under the "privacy" tab
09:14:18 [wonsuk]
wonsuk has left #privacy
09:14:32 [jmorris]
pat: to clarify re 2004 code of practice - it was successful because mobile operators were in highly regulated environment
09:14:37 [ifette]
hendry, chrome will also ask you on each site
09:14:45 [ifette]
(as will any browser afaik)
09:14:49 [hendry]
i have taken a few screenshots battling to turn off geolocation (on already authed sites) http://www.flickr.com/photos/hendry/sets/72157624456158938/
09:14:51 [jmorris]
john: 2004 included extra layers for children
09:15:42 [hendry]
ifette: i think the desire is there. i need to turn it off from time to time. ;)
09:16:01 [jmorris]
robert?: use cases mixed up - gambling , predators, different use cases
09:16:12 [ifette]
hendry, please do not use ifette: as then the minutes will have me reflected as saying that.
09:16:20 [ifette]
hendry, in chrome you could have done it much more simply
09:16:24 [ifette]
click on the little target in the url bar
09:16:26 [npd-test]
npd-test has joined #privacy
09:16:30 [ifette]
and you can change settings for the site you're on
09:16:39 [jmorris]
cullen: how did gambling work
09:16:45 [bryan_sullivan]
do any of the browsers make it easy to create a user-specific button to turn geoloc on/off?
09:16:47 [eisinger]
also the website can already locate you pretty good with only your ip
09:16:53 [ifette]
in one click
09:16:56 [jmorris]
.. gambling restrictions on kids
09:17:18 [hendry]
is that for all open tabs btw?
09:17:19 [jmorris]
john carr: when you apply to gambling site, you allow credit, other checks
09:17:33 [ifette]
hendry if you clear it, future requests will fail
09:17:36 [ifette]
on all tabs/windows
09:17:47 [ifette]
the setting is stored for the origin, not tied to a window/tab
09:17:58 [jmorris]
.. 5% cannot verify with databases, they must use other papers
09:18:17 [jmorris]
dsinger: is there error the other way- children in databases?
09:18:25 [hendry]
i mean for all running apps (different origins)
09:18:33 [ifette]
the setting is per origin

Kasey Chappelle, Vodafone
09:18:58 [ifette]
i find it rather unlikely someone suddenly decides they want to turn off geolocation for all sites
09:19:06 [jmorris]
.. paper is at http://www.w3.org/2010/api-privacy-ws/papers/privacy-ws-15.pdf
09:19:10 [ifette]
we have these theoretical discussions, in practice it doesn't seem to happen
09:19:22 [hendry]
ok,we'll debate this later :)
09:19:35 [jmorris]
Kasey: privacy is the right to decide - informational self-determination

09:23:07 [jmorris]
.. EU is relooking at data protection directive, US is proposing privacy laws,
09:23:45 [jmorris]
.. old distinctions between controller, processor, subject are blurring
09:24:18 [jmorris]
.. some consistent principles around the world
09:24:50 [jmorris]
.. if you meet these principles, companies will avoid privacy fiascos
09:25:25 [jmorris]
.. key principles : transparent notice, informed choice, access/correct/delete, minimize/delete
09:25:49 [jmorris]
.. privacy policies ... 4000 words... not read
09:26:01 [rbarnes]
tlr: kasey is pretty well audible in the back

@tlr just about
09:27:29 [jmorris]
kasey: if regulators decide how privacy is done, then this will chill innovation on privacy
09:27:43 [jmorris]
.. security does not equal privacy
09:28:00 [jmorris]
.. security is how/what info is being accessed, but not the why
09:28:01 [drogersuk]
@dsinger - I brought my camera for a laugh just to see if anyone would complain - I walked in and some guy had a huge lense taking pictures of everyone
09:28:09 [jmorris]
.. this is broader that geolocation
09:28:26 [fjh]
can barriers to entry created by regulation also create possible monopoly structures due to the need for scale for meeting the regulations?
09:28:42 [jmorris]
.. embedded code in handset can create profiles

frederick: is "informed" a well defined term?
09:29:31 [jmorris]
kasey: opened, evolving area
09:29:43 [jmorris]
.. 4000 word policy is not "informed"
09:30:00 [jmorris]
frederick: "reasonableness"?
09:30:03 [ifette]
4000 seems pretty short :)

brian: any specific characteristics that would help us understand when users have been informed
09:30:34 [drogersuk]
@dsinger that's how we identified German morse code operators in the war
09:30:56 [jmorris]
kasey: if we continue to focus on consent only, we have failed
09:31:13 [jmorris]
.. one has to balance experience - we need to rethink fundamental structure
09:31:28 [jmorris]
.. look to primary purpose, secondary purpose distinction
09:31:49 [jmorris]
simon: have you looked at where data are located?
09:31:54 [karl]
interesting. Do you give enough information to make a decision? What's happening with regards to intimate discussions between two persons. Since there are devices and private companies in between, they carry neutrally (bits transport) or not the information (data mining)
09:32:28 [jmorris]
kasey: this is part of the problem - my employer is based in UK, but if online service is accessible everyone, what rules apply?
09:32:44 [jmorris]
.. perhaps moving toward global standards
09:32:58 [jmorris]
question: national content standards
09:33:18 [jmorris]
kasey: national content standard need to still apply
09:33:28 [jmorris]
.. privacy standards may be different
09:33:50 [jmorris]
.. reactions are fairly similar - giving choices is what matters
09:34:30 [drogersuk]
solution is we need a global government with global laws. Is that a possible outcome of this workshop?
09:34:31 [jmorris]
s/robert?/David Rogers/
09:35:32 [jmorris]
tlr: moving to general discussion
09:35:57 [jmorris]
.. karl talked about forgetting things in real life, not online
09:36:27 [jmorris]
.. john talked about specific regulatory framework in UK - note tension between rule and reality
09:37:21 [jmorris]
.. kasey talked about some regulatory frameworks .. need to tell people "why" you want to use their data
09:37:47 [jmorris]
.. common theme - there are hard and fast rules that do not map into social reality
09:38:23 [jmorris]
john carr: when I was 15, I wanted to get a pint of beer in pub
09:39:07 [jmorris]
.. we should not strive to match the social reality
09:39:47 [jmorris]
.. offering of internet is aimed of family homes all over world -- we have to stop thinking about children as an afterthought
09:40:05 [fjh]
q+ to ask how to enable social mechanisms via technology
09:40:20 [jmorris]
.. we should shift our mindset to recognize that lots of children are online
09:40:43 [jmorris]
ian: to do anything useful, you must know who is a child
09:40:54 [jmorris]
.. in US, we are against national ID card

@karl, completely agree but most users do not have a clue about anything technical, we need to bring it down some notches to what is understandable
11:19:19 [alissa]
privacy = fair information practices
11:19:35 [alissa]
... no shortage on priv principles
11:20:33 [alissa]
IETF applies hybrid of PbyD and "priv by policy"
11:21:17 [alissa]
... PbyD is more understandable to engineers
11:21:25 [alissa]
... although it's often advocated by non-designers
11:21:52 [alissa]
role of SDOs
11:22:24 [alissa]
... some orgs are strongly focused on standardizing everything -- 3GPP, OMA, ETSI, ITU-T
11:22:47 [alissa]
... then proprietary: not Internet-based
11:23:02 [alissa]
... then built on top of standards
11:23:18 [alissa]
... need for standards decreases as you go up the protocol stack
11:24:14 [alissa]
... priv seals and certifications haven't provided a lot of value
11:24:28 [alissa]
... IETF has remained generic in protocol definition
11:26:14 [alissa]
IETF often standardizes after implementations and deployments exist, limiting designability

HT: if your IP address never changes, sites you visit will see it all the time, but there are standardized solutions to change that
11:40:54 [alissa]
Sören: theme seems to be need to cut down to simple decisions
11:41:14 [alissa]
... on other hand we have frameworks and guidelines
11:41:24 [alissa]

15:27:27 [darobin]
... once you have permission from the user, the spec says she should be able to change her mind
15:27:38 [darobin]

15:28:09 [darobin]
... (demonstrates infobar in chrome)
15:28:46 [darobin]
... an icon in the address bar tells you that the page is using geo, and you can revoke
15:28:53 [darobin]
... it's accessible, but that's the easy case
15:29:18 [darobin]
... (shows the same case, but with google maps embedded in a third party site)
15:29:38 [darobin]
... should we show this as google requesting or as the 3rd party site requesting?
15:29:43 [darobin]
... it's not an easy question
15:29:55 [darobin]
... we ask the user for what's included
15:30:32 [darobin]

15:32:30 [darobin]

jochen: from an implementers' perspective, you know these things and you have to deal with them
15:45:24 [darobin]
dom: have you submitted that to the WG?
15:45:27 [darobin]
ian: yes
15:45:35 [darobin]
... and our solution is conforming
15:45:50 [darobin]
... but had the spec been wrong, we would have ignored it
15:45:59 [darobin]
tlr: the specification could use some clarification, possibly
15:46:30 [darobin]
dka: there might be a disconnect between the creation of the API and the implementation
15:46:46 [darobin]
... google was a key driver in the development of the API, so we need to work on closing that loop
15:47:10 [darobin]
cullen: problems for mobile implementation, the icon is a problem?
15:47:21 [tlr]
s/the specification could use some clarification, possibly/the specification seems clear if you read it with a spec-writer's mindset. interesting that there's a need for clarification/
15:47:23 [darobin]
jochen: no, there wasn't much thought put into what the UI ought to do
15:47:39 [darobin]
jmorris: but that's because google was against us saying anything useful about the UI
15:47:58 [darobin]
cullen: is your complaint that we chose the wrong thing or that you couldn't figure out which is best?
15:48:15 [darobin]
jochen: including these sections in specs is good
15:48:25 [darobin]
cullen: missing the details of what you were missing, we want it
15:48:47 [darobin]
tlr: think we will come back to this in the final discussion
15:48:56 [darobin]
dka: implementation experience is crucial

Marcos Caceres, Opera — Privacy of Geolocation Implementations
15:51:08 [darobin]
marcos: I looked at chrome, opera, mobile safari
15:52:02 [darobin]
... firefox
15:52:26 [darobin]
... I made a critical framework including Accessibility, Control, and Confidentiality
15:53:00 [jochen]

(the book/author are "Database Nation: The Death of Privacy in the 21st Century", by S. Garfinkel)
15:53:19 [darobin]
... in iOS, all apps must get user permission
15:53:33 [dom]
-> http://www.w3.org/2010/api-privacy-ws/papers/privacy-ws-21.pdf Marcos' paper: Privacy of Geolocation Implementations
15:54:11 [dom]
it actually was The Future of Reputation: Gossip, Rumor, and Privacy on the Internet, Solove
15:54:15 [darobin]
... lots of modal dialogs lead to click fatigue, you can't see what's on the website while the dialog is up
15:55:10 [darobin]
[less scribing for Marcos as he has slides people can read]
15:55:42 [darobin]
... iOS has 50 pages of unreadable text with unclickable URLs
15:55:47 [darobin]
... it's super frustrating
15:55:48 [dom]
"hard to read gray" (tm)
15:55:57 [darobin]
... but users probably just don't care
15:56:28 [darobin]
... revocation can only be done in a very well hidden screen
15:56:48 [darobin]
... potentially that could be improved [speaker enjoys udnerstatements]
15:57:01 [darobin]
... in v4 there's an indicator
15:57:10 [darobin]
... there's a semiotic connection there
15:57:51 [darobin]
sören: I had a problem with the first dialog — does "current" location mean current = now or current as in always current
15:57:57 [darobin]
marcos: yes, it's unclear
15:58:08 [darobin]
alissa: does the permission time out after 24h
15:58:09 [dom]
[I wonder if any of the implementations make a distinction between watchPosition() and getCurrentPosition() ]
15:58:11 [DKA]
[also, it does not ask you "remember? yes/no"
15:58:12 [darobin]
marcos: I don't know
15:58:45 [darobin]
... verdict: iOS not very accessible, some level of control, some level of confidentiality
15:59:25 [darobin]
... moving on to firefox
15:59:50 [darobin]
... more control, non-modal, access to learning more about the privacy policies
15:59:55 [karl]
[It would be fun to be able to define shapes of location forbidden for tracking. Automatic switch… but how do you know you are out of the shape :)
16:00:04 [darobin]
... the FF guys have done great work
16:00:07 [darobin]
... but
16:00:31 [darobin]
... if you want to do more advanced tasks, you gotta go to access:config
16:00:37 [darobin]
... way too technical
16:01:14 [darobin]
... it will even warn you against hacking it
16:02:01 [darobin]
... verdict: hard to manage sites, control hard to change, hard to make confidential
16:02:19 [darobin]
tlr: can you remind me how I can find out whether a site I'm using is tracking me?
16:02:35 [darobin]
marcos: it's somewhere under tools
16:02:39 [darobin]
... not easy
16:02:45 [darobin]
... looking at Opera now
16:02:56 [darobin]
... similar to FF, no access to privacy policy
16:03:28 [darobin]
... reason for that is that on first use of the feature we display T+C for the service
16:04:03 [darobin]
... it's quite bad, it has links but no back button so that if you click one of the links you lose the policy and can't read the rest
16:04:12 [darobin]
... this is what happens when you mate lawyers and UI people
16:04:18 [darobin]
... we are going to fix that
16:04:43 [darobin]
... FF approach better
16:05:06 [darobin]
dka: this is the geo policy right, not the requesting site's policy?
16:05:10 [darobin]
marcos: correct
16:05:37 [darobin]
... our location provider dialog is also in opera:config
16:05:44 [darobin]
... a little more accessible than the FF version
16:06:07 [darobin]
... some built a fake Opera Unite geo provider so that people can fake their own location
16:06:13 [darobin]
... which is handy
16:06:34 [darobin]
... the contextual help for the dialog says "no data available"
16:07:01 [darobin]
verdict: accessibility yes, control yes but hidden, confidentiality yes
16:07:25 [darobin]
... now looking at chrome
16:07:44 [darobin]
... kudos to the chrome guys for solving the embedding problem
16:08:00 [darobin]
... we people who work for browser vendors are kind of unique
16:08:37 [darobin]
... verdict: accessibility yes, control yes but no control over provider, confidentiality yes
16:09:14 [darobin]
... do we need more standards for UI? or leave it to the market?
16:09:26 [rbarnes]
side-by-side comparison of the four desktop implementations on Mac OS: http://geopriv.dreamhosters.com/w3c/w3c-geolocation-implementation.gif
16:09:28 [darobin]
... equivalent to the padlock for https
16:09:52 [darobin]
... browsers have different icons, should we align? and if so how?
16:10:08 [darobin]
... we compete on user experience
16:10:21 [dom]
[the limit of UI indicators is: how many of them can you usefully deploy as the number of indicators grow (e.g. with the number of APIs]
16:10:28 [darobin]
sören: there's also the RSS icon where the market found a solution
16:10:56 [darobin]
karl: what's frustrating with multi browsers is that you have to control your preferences n times
16:11:02 [darobin]
... it would be good to have a common standard for that
16:11:12 [darobin]
marcos: people use different browsers for different things
16:11:19 [darobin]
[scribe agrees with karl]
16:11:53 [darobin]
chris: am I gonna to have to go through all these menus and indicators?
16:12:04 [darobin]
marcos: depends on how much you care about revoking and various services
16:12:05 [rbarnes]
+1 to karl / ian / scribe
16:12:14 [darobin]
... the ccritical side is the server-side too
16:12:28 [darobin]
... we're going to fix it over time though, don't know how but that's why we're here
16:12:36 [karl]
[it could be multiple profiles, but a standard format across browsers for preferences including privacy settings would be super helpful]
16:13:27 [darobin]
sören: I think it's okay to have complexity because at one point in time you will have an addon that hides that complexity. We can have complexity so long as there is a way for third-parties to fix it
16:13:35 [darobin]
marcos: there is no API to access this though
16:14:02 [darobin]
tlr: for our purpose there is a UA that has access to a sensor, there are inherent issues with that and how it interacts with the web
16:14:18 [darobin]
drogersuk: in desltop we have more screen space, in mobile it's constrained
16:14:33 [darobin]
... you run the risk of having lots of blinking lights that make things hard to use
16:14:49 [darobin]
marcos: yes, we're looking for solutions
16:15:57 [darobin]
richard: a lot of the implementation concerns ought to be rolled back into the spec
16:16:09 [darobin]
... it's striking how similar the implementations are
16:16:21 [darobin]
marcos: people are violently against this, there might be a new WG?
16:16:42 [drogersuk]
no need to create another working group
16:16:53 [drogersuk]
confront this head on in our existing working groups
16:16:57 [drogersuk]
(my view)
16:17:09 [darobin]
ianis?
16:17:29 [darobin]
ioannis up now
16:17:30 [karl]
s/ianis/Ioannis/
16:17:56 [darobin]
ioannis: location privacy is not just about not revealing where you are right now, but mostly about past locations
16:18:30 [karl]
[location privacy idea: if you are at less than 500m from this person, hides me]
16:18:31 [darobin]
... some services don't require that you identify yourself to use geo
16:18:41 [darobin]
... eg google maps don't require a google account
16:18:46 [darobin]
.... we like that usage
16:18:50 [karl]
s/hides/hide/
16:19:14 [darobin]
... we want to provide unlinkability between the locations that have been provided
16:20:09 [darobin]
... threat comes from unique identifiers (IP addresses, esp ipv6, cookies, LSO) plus geo
16:20:18 [karl]
[people laughing at http://ncowie.files.wordpress.com/2009/04/xfgeye1iupqro5pold.jpeg]
16:20:22 [darobin]
... there are some defense mechanisms
16:20:33 [darobin]
... (shows the panopticlick study)
16:20:52 [darobin]
... footprinting attack remove the need for cookies
16:21:17 [darobin]
... 94% of browsers are unique if you have java/js/flash
16:21:48 [darobin]
... footprinting can therefore be used in conjunction with geo, which can lead to building location traces
16:22:11 [darobin]
... services might not know to whom the location belong, but it only takes one idenfitication to create that link
16:22:19 [darobin]
... FB Share for instance is enough
16:22:45 [darobin]
... another attack can be built on the fact that people move in restricted spaces and move in restricted patterns
16:23:47 [darobin]
... the threat becomes more interesting if we think of 3rd party geo providers who accumulate information sent to many websites
16:24:17 [darobin]
... they concentrate a lot of information
16:24:42 [darobin]
... solution approaches with privacy by policy
16:25:02 [darobin]
... but these are not tamper proof against stronger attackers not deterred by regulation
16:25:09 [darobin]
... and accidental disclosure happens
16:25:54 [darobin]
... looking at privacy by design, there's minimisation (for geo, granularity of information)
16:26:08 [darobin]
... but this does not solve the 3rd party geo provider issue
16:26:20 [darobin]
... and also only works when precise location is not required
16:26:51 [darobin]
... we could decrease footprinting, e.g. suppressing Java
16:27:39 [darobin]
... we could have a monitoring process that computes our general privacy exposure
16:27:45 [dom]
[but who monitors the monitor? :) ]
16:28:02 [karl]
[need to be on the browser side?]
16:28:25 [darobin]
... maybe the W3C could enforce some additional measures for web browsers
16:28:58 [darobin]
tlr: we might persuade, not sure we can send the conformance police
16:29:36 [darobin]
henry: what you're pointing out is that geo info is sent and can be tied to identity — what is needed is a very clear way for users to change identities, not sure it is possible
16:29:58 [darobin]
... currently at the SSL layer, browsers send certificates without asking you, it is hard to change
16:30:10 [darobin]
... FF working on an identities framework
16:30:17 [darobin]
... privacy is identity plus extra information
16:30:27 [darobin]
... if you can't change the identity you're in trouble
16:30:49 [darobin]
tlr: no, there are ways of tracking users based on incidental information — no need for actual identity to track
16:31:00 [darobin]
... how do we avoid unintended user identification
16:31:14 [darobin]
dave: it's very difficult to prevent footprinting attacks
16:31:49 [darobin]
dave: you said you wanted to reveal when the user has revealed "too much". How? What is too much?
16:32:07 [darobin]
ioannis: we would need a metric, we don't have it now
16:32:37 [darobin]
... it depends on the level of precision of your location, the frequency, the location of what it is (house or other)
16:32:40 [bblfish]
bblfish has joined #privacy
16:32:43 [darobin]
... lots of contextual information needed
16:32:54 [darobin]
... I don't think that we have the means to do it right now
16:33:24 [darobin]
dom: related to massive data aggregration, does any implementation distinguish between getPosition and watchPosition?
16:33:37 [darobin]
... and throttling
16:33:45 [darobin]
marcos: Opera does, though it's a bit hidden
16:34:05 [darobin]
dom: you're talking about the service provider, not at the API level
16:34:08 [darobin]
marcos: I don't know
16:34:20 [darobin]
sören: wouldn't it be great if Amaya implemented geo?
16:34:30 [darobin]
tlr: we'd need a javascript runtime first...
16:34:41 [darobin]
marcos: we haven't had that many issues, no showstoppers
16:34:58 [darobin]
ianf: suggestions that now that we have this experience we shold shove it in the spec
16:35:05 [karl]
[just for clarification, Amaya is not a reference implementation, but a tool to test a few things]
16:35:10 [darobin]
... I think that we're still experiementing, shouldn't overspecify
16:35:23 [darobin]
... great to document best practices, but we should be careful with detail
16:36:02 [darobin]
richard: I wasn't thinking about making it normative, but document it in the spec so that it is captured
16:36:19 [darobin]
jochen: it is important to keep in mind when writing specs that someone will have to implement it
16:36:46 [darobin]
dka: this is important because geo is rechartering, this is useful feedback
16:37:02 [bblfish]
so one issue is simply that it should be possible for the user to change their logged on identity. I think Firefox is working on the Weave plugin, which I suppose I am now thinking is an important solution.
16:37:06 [darobin]
... what can we pull out of this that could apply to DAP, eg the camera?
16:37:19 [darobin]
... can we apply the geo lessons to camera, etc. or is it all too different?
16:37:39 [bblfish]
then there are issues with client certs. Chrome has a bug issue on this http://code.google.com/p/chromium/issues/detail?id=29784
16:37:39 [darobin]
jochen: one basic thing is that it ought to be asynch
16:38:47 [darobin]
robin: all the DAP APIs have asynch security entry points
16:39:09 [darobin]
karl: do we know how many people want to share their location versus people who just want to know their location?
16:39:18 [darobin]
jochen: I don't have data about that
16:40:17 [darobin]
dom: notion that accessing the data locally will have a different impact than getting it off the network — though of course if you have a map it goes back to the map provider
16:40:33 [darobin]
ianf: most browsers use a remote service to get the lcoation anyway
16:40:48 [darobin]
tlr: that's one provider though, as opposed to an indeterminate number of sites
16:41:21 [darobin]
henry: issue with javascript and asynch, what happens if your browser is a web server and your geo data is at a URL
16:41:40 [darobin]
[scribe sort of loses the point]
16:42:00 [darobin]
marcos: it's always more complicated, switching to REST doesn't change the fundamental problems
16:42:51 [darobin]
drogersuk: issue with passing information in URLs
16:43:05 [darobin]
marcos: that's not a problem, the communication channel needs to be secure
16:43:20 [darobin]
