How much EXIF information is tracked by photo sharing sites?
http://regex.info/exif.cgi

I often post photos to photo-sharing sites, whether for the
purpose of social networking (pinterest, facebook, etc)
or for Usenet posts (tinypic, flickr, etc) or for personal
sharing (iCloud, dropbox, google drive, etc).

The EXIF, as you know, can reveal exactly where and when
the photo was taken, and even what camera was used, and, of
course, the time and date, etc, the combination of which could
easily reveal intensely personal information.

When I DOWNLOAD those pictures, generally (always?) the
EXIF information seems to be stripped out.

But ... how much of that personal EXIF information is retained by
the web site (and used for their possibly nefarious purposes)?

If you upload X, assume the web site has X. If that X contains all your
EXIF data, assume they keep it.

There are utilities to strip EXIF data from a photo. In Photoshop, it
isn't so obvious, you have to export to web. That gives you ability to
strip most of the exif data out.

Dude, a few years ago nobody would have thought it possible (or even
constitutional) in the western world that social media and cloud
services treat your data as their property, that postal service retain
every sender/recipient address, that secret services read and store all
your e-mails, passwords and browsing profiles. And yet, we were shocked
to learn that all this is common practice today.

So you just have to assume that every bit of information that leaves
your local network is intercepted, stored and evaluated. If it is
encrypted it is either decrypted today, or stored for decryption in the
future.

Sorry to break the news to you.

In Photoshop or Lightroom you can select slightly different levels of
EXIF data you choose to include or exclude with the exported image file.
Photoshop: None: Copyright; Copyright & Contact Info: All Except Camera
Info: All.
<https://dl.dropbox.com/u/1295663/FileChute/screenshot_996.jpg>

Lightroom: Copyright Only; Copyright & Contact Info Only: All Except
Camera & Camera RAW Info: All Metadata
...and an option to "Remove Location information."

Evaluated? I suppose if it's a photo of a military installation or some
other super secret place, maybe.

Nefarious purpose? Unless sensational, or above, what can they really do
about knowing you shot a photo of Suzie Q in front of the Prado at 14:55
UMT?

It's one thing to assume, while it's another to actually know.
I asked to figure out if anyone actually knows, since I don't.

Yes. I often convert to GIF, just to get rid of the EXIF information:
$ convert pic.jpg pic.gif

Or, I just strip out the EXIF information:
$ for f in *.{JPG,JPEG,jpg,jpeg}; do convert -strip $f $f; done

But, the purpose of asking here was to figure out if there are any
known cases where the web site made use of the EXIF information.

Certainly if you know of a picture-sharing site that *keeps* the
EXIF information intact, that would be immensely informative.

Sorry, but how is this "intensly personal information"? If you have
Lightroom set to add your personal details it would certainly be personal
infromation, but hardly "intensly", that would be if you also add your
social security number and other more intimate details about yourself.

Which just means that the thumbnail, or scaled down version of the image,
has EXIF stripped, and that's the version you (and maybe others) can
download, meaning they've taken steps to conceal the somewhat personal
information there is in the image.

> But ... how much of that personal EXIF information is retained by

While some social web sites surely create a local scaled down version of
the image, and toss the original, I'd say most keep the original on disk
for future re-scaling.

And with regards to the supposed "nefarious" purposes, whatever purposes
could they have with knowing your camera model, the date the image was
taken and possibly where it was taken? I mean, in theory it could be used
to give you ads about going back to Thailand a year after, but that's
hardly "nefarious", and if you're the kind of person that thinks targeted
ads are nefarious, then you're also the kind of guy that strips the EXIF
yourself first, and upload it in another name, using a secure email address
:-D

Flickr, obviously, keeps the EXIF data. They display it on the photo page
and even the location if you allow it, they also use it to gather
statistics about cameras. Not sure what "nefarious" purposes they COULD be
using it for.

In Photoshop if you use "Save for web" the EXIF is stripped, if you use
"save as" it's kept.

If I snap a picture of a pink flower in the open-air foyer
at the AIDS clinic while I'm supposed to be at work, and the
EXIF information shows almost exactly when & where I was, that's
(by it's very revealing nature) certainly intensely
personal information (it's meta-information but intensely
revealing nonetheless).

flickr does. I know someone who routinely posts pictures with the exit

If you want to alter or get rid of EXIF data, you can use exiftool:

http://www.sno.phy.queensu.ca/~phil/exiftool/

Free; binaries available for Windows and Mac, (Perl) source for
everything else. It's a command line tool, although I think that there
are GUI front ends available.

Seriously? I mean, you snipped away parts of my message where I said they
show it on the photo page:

<https://www.flickr.com/photos/jonaseklundh/15351219105/>

Click "Show Exif".

Also, if you download the original, all the Exif is there.

And in this supposed "intensly personal information", where can I read:

1. It was taken by you
2. You are a patient of said clinic

For the all the supposed EXIF-reader knows, it was taken by someone
visiting the clinic because they've sponsored it with money, or they're a
gardener that works in many garens in that area.

Again, this isn't "intensly personal information" if it requires tons of
assumptions.

That might be slightly nefarious (that is, if my member weren't so glorious
:), but what would the purpose be? I mean, Flickr, or such service,
wouldn't make any money from posting this :)

Exiftool works nicely.
Here are some other ways to remove the EXIF data.


$ sudo apt-get install imagemagick
$ convert -strip pic.jpg pic_sansexif.jpg
$ for i in *.{jpg,JPG}; do echo "Cleaning $i EXIF"; convert -strop $i $i;
done

$ sudo apt-get install exiftool libimage-exiftool-perl
$ exiftool -all= foo.jpg
$ for i in *.{jpg,JPG}; do echo "Cleaning $i EXIF"; exiftool -all= "$i";
done

$ sudo apt-get install jhead
$ jhead -purejpg *.jpg
$ for i in *.{jpg,JPG}; do echo "Cleaning $i EXIF"; jhead -purejpg $i;
done

I don't know how to remove EXIF with exiftran (do you?).
$ sudo apt-get install exiftran

$ sudo apt-get install exiv2
$ exiv2 -rm pic.jpg pic.jpg ???
(I'm not sure the sytax to use the "rm" option to remove EXIF data)

A. Beck:
I downloaded this photo of mine
<https://www.flickr.com/photos/primeval/15490456502/in/photostream>
from my Flickr stream. The EXIF is intact.

That's the way I want it. I make and post many photos of small
arthropods for my "clients," who include the Encyclopedia of Life, the
Maryland Biodiversity Project, and anyone in the world with an Internet
connection who would like to view or download my photos and use them
for their own non-commercial purposes under the Creative Commons
license. Once in a while a commercial customer licenses one of my
photos for publication. My income from this is utterly insignificant.

My scientific photos would be useless without accurate date/time and
location information in the EXIF. I have Photoshop set to preserve this
data when I export to JPEG for the Web.

It is possible to set Photoshop to not include EXIF when exporting.
That would be your best bet if you want a certain measure of anonymity.

My first recommendation for those who seek anonymity is that they get
off the Internet. One can't have it both ways; every time one uses the
Internet one sends personal information to a remote server. It is
impossible to be anonymous on the Internet. A person who wishes to hide
should give up their drivers license, their automobile(s), their real
estate, utilities, checking account, job, retirement annuity, and such
like, and consider leaving their home in the developed world for a much
less developed country. Of course, one needs a passport to do that, and
one must supply a considerable amount of personal information to get a
passport. Chances are some of that information passes through Justice
Department computers and is automatically scanned for red flags. It is
extremely difficult and risky to attempt to counterfeit a U.S.
passport.

For what "nefarious purposes" do you think people might use your EXIF?
Might someone learn when you visited the Grand Canyon or the Eiffel
Tower? (Nefarious people already know where these places are.) Got more
than one wife/family? Then you'll definitely want to unplug.

It is verified that the USPS records and reports to security
authorities a relatively small amount of sender and receiver data.
WaPo, 27 October "In a rare public accounting of its mass surveillance
program, the United States Postal Service reported that it approved
nearly 50,000 requests last year from law enforcement agencies and its
own internal inspection unit to secretly monitor the mail of Americans
for use in criminal and national security investigations."

50,000 out of approximately 212 billion pieces of mail. That's about
2.358x10e-5%.

It is also not true that the NSA has the capability of reading every
e-mail sent in the world or listen to every phone call. SIGINT is labor
intensive; most of the people at NSA are so busy that they don't have
time to read their own e-mails.

Not so, at least for recent versions of Photoshop. In CS6, CC, and CC
2014, saving metadata is an option in the "Save for Web" dialog.

You have to assume that any metadata like EXIF or text you post into the
internet will be scanned by malevolent agents now or in the future.

Basically if you are worried strip the EXIF data off and/or resample the
image down to a smaller size and watermark it. That way when someone
attempts to use your copyright images without permission you can if
necessary stamp on them. I have only done it a couple of times.

Normally I will grant permission and provide the full resolution image
on condition that I get a copy of the book that is using it. It is
madness to make the full resolution of a valuable image available free.

And probably resampled and compressed to a standard canonical JPEG
encoding as opposed to the custom qtables out of the camera.

Probably all of it so be careful what you upload. Also read the small
print very carefully many of these photo "sharing" sites will lay claim
to them gaining your image copyright hidden in their terms of use.

Same sort of issues with facebook etc where people often provide enough
information to allow thieves to target empty houses whilst the owners
are mindlessly tweeting and facebooking their holiday snaps.

How so? By your presence there you have revealed this "intensely
personal information" to your co-workers, your clients, and passers-by
who may have seen you enter the parking lot in the morning. Your bank,
the IRS, the SSA, and various county or parish and state and local
agencies know where you work. Medical insurance companies know where
you work. Your friends, family, and neighbors are likely to know where
you work. People talk, they share information in person and on the
Internet.

But once more--as pointed out in this thread, there are a number of
ways to keep your affair with the flower secret. The best is to not
photograph the flower. Second is to not share the photograph, but, of
course, the camera or camera phone with which you made the photo could
be stolen with EXIF and other revealing information intact. Best not to
photograph the flower or anything else. Get rid of all cameras that can
record EXIF. Keep your photos to yourself.

Yes. Flickr displays it on demand if it is included with the photo.

That's the idea. Many people, including me, need to make that
information available to persons who view their photos. This is the
Information Age, not the Dark Age.

There is just a tad too much paranoia to this. I usually retain full
EXIF data and for many shots I retain GPS Geo tagged location
information as that gives me another sort criterium, and can provide
some interesting data for those I share images with.
So if you open this image and check the EXIF, you will find a whole
bunch of information in the EXIF metadata including location data for
the 1200+ shots I took that particular day.

<https://dl.dropboxusercontent.com/u/1295663/Shared%20Images/Automotive/DNC4947-Edit-1.jpg>
...and

the location from the Lightroom Map Module.
<https://dl.dropbox.com/u/1295663/FileChute/screenshot_998.jpg>

Nor am I. I label my photos on Facebook and in Flickr with "Made at
Gambrills, Maryland, on DD MMM YYYY." Or other location, as
appropriate. Try to imagine the National Geographic or a newspaper
publishing photos in isolation, not saying where or when they were
taken. That would render most of the photos entirely useless.

Who are these malevolent agents? Why would they care that I made this

<https://www.flickr.com/photos/primeval/15335834362/in/photostream> at
my home at 39°04'40.61" N 76° 39' 33.46" W? Is that information useful

Yes, but then you are not National Geographic, or even a newspaper. Even
they do not publish all the photos they take.

Get Exiftool and search the web for the best commands to clean out

The *ONLY* safe assumption you can make on that is that they'll collect
and use *EVERY SCRAP OF INFO THEY CAN GET THEIR HANDS ON*, no matter how
private, trivial, crucial, or otherwise. If you hand them info,
knowingly or not, they're going to use it. Period.

And unless things change massively, neither you, nor anyone else, will
*EVER* know - Someone *MIGHT* be able to do some sort of commando-style
raid and get it out of somebody at gunpoint, but these outfits that
collect information will *NEVER* willingly reveal how much or how little
they collect and/or try to use. There's even less chance that they'll
tell you how they use it or why.

Very perceptive. No, I'm not. And I don't publish all the photoss that
I make, either. But you missed the point, which was, I think, that
failure to reveal information about the photos that one /does/ publish
diminishes the usefulness of the photos.

Nospam is right. They started photographing *every* piece of mail,
and holding it for 30 days, I think, after the anthrax scares.

It's in the NY Times article from yesterday, which I found after

Several of them lay claim to worldwide rights to exploit your uploaded
images hosted on their site for their commercial gain. See for example:

http://www.wiredcanvas.com/2012/12/image-copyright-social-media/

Copyright still remains with you but in signing up with them you have
waived it and they are free to make money from your images.

When they show the pictures to people who visit their site (that's why
you put the pictures there, right?) they are exploiting them for
commercial gain by accompanying them with ads. Why else would they do
it?

> Copyright still remains with you but in signing up with them you have

So what? You signed up and you uploaded the photos. Unless the photos
are ones you could have sold (then why did you upload them?) it doesn't
cost you anything to have them make money. You get free hosting for
your photos, they get a chance to make a bit of money: an exchange of
value benefiting both parties.

The question was never *how* to strip EXIF data (that's easy).
I habitually stripped EXIF data well before I ever posted the question.

How to remove exif data:
====================================================
$ sudo apt-get install imagemagick

$ convert -strip pic.jpg pic_sansexif.jpg

$ for i in *.{jpg,JPG}; do echo "Cleaning $i EXIF"; convert -strop $i $i; done
====================================================
$ sudo apt-get install exiftool libimage-exiftool-perl

$ exiftool -all= foo.jpg

$ for i in *.{jpg,JPG}; do echo "Cleaning $i EXIF"; exiftool -all= "$i"; done
====================================================
$ sudo apt-get install jhead

$ jhead -purejpg *.jpg

$ for i in *.{jpg,JPG}; do echo "Cleaning $i EXIF"; jhead -purejpg $i; done
====================================================
I don't know how to remove EXIF with exiftran (do you?).

$ sudo apt-get install exiftran
====================================================
(I'm not sure the sytax to use the "rm" option to remove EXIF data)

$ sudo apt-get install exiv2

$ exiv2 -rm pic.jpg pic.jpg ???

You need to read the "TERMS" section on smugmug.com.

First, they do not authorized you to post photos that
you do not own or otherwise have legal copyright license
to. Hence they of course do not ask for a license for
such! And they may permanently ban you from the site if
they descover you've posted such materials.

As to your photos, where you do have copyright
ownershipt, the TERMS say "by uploading and/or posting
any User Content to the Site or otherwise by using the
Services, you grant SmugMug a perpetual, nonexclusive
and royalty-free right to use the User Content ..."

They clearly do have a licence to use your
photos. (Otherwise they would not be legally able to
display them to any user other than you!)

While 99.9999% of the information collected is useless, there is
something in there useful to someone regarding someone else.

That 0.00001 % is the Paydirt.

It is so cheap to collect the data and so cheap to keep the data that it
is 'profitable' in the long term. (Profitable may mean money wise,
tactically, politically ...) And it's only getting easier and cheaper.

You should have posted the remainder of the terms where it states that
the license is so that they may display the photos on the website which
is what I am paying them to do.

You responded to this: "Certainly with FB, and some others I have seen,
by signing up with them you grant them a non-exclusive royalty-free

license to sub-license my photos to whomever they please.

Actually, you're the one who's wrong. The words "You grant..." and
"...right to use..." are all thats required to legally allow them (Any
"them", be it Facebook, SmugMug, Flickr, or whomever) to do *ANYTHING
THEY WANT* with whatever image you hand them. While they may (and in the
case of SmugMug, it looks as though they do) go on to try to "explain"
what they're planning to do, that explanation *IS NOT* a restriction on
what they *MAY* do, should they decide they want to.

Put another way, when you upload an image to some site with a user
agreement that contains similarly worded terms that don't *SPECIFICALLY*
prohibit them doing <pick a something> with your image, then you've just
handed them the rights to do anything they might care to do with it.
*ANYTHING*. If you don't like that fact, don't upload an image to them.
That's really your only option, since no for-profit outfit is going to
(or more accurately, their lawyers won't *LET* them) close the door on
any possibility of exploiting anything they can get their hands on to
make a buck off it.

On the other hand, it's *POSSIBLE* that someone with deep enough pockets
may some day manage to bring a case that blows such crap out of the
water - A while back, a precedent was set that effectively shot holes in
so-called "shrink-wrap licensing" - Licenses that basically say "by
opening the package, you agree to whatever we damn well please, and if
you don't like that, tough shit". Website TOS statements are a form of
of SWL, at least in my non-lawyerly opinion. The problem is this: Do
*YOU* have what's needed (in terms of time, money, lawyers, etc, etc,
etc) to chase this to a conclusion that stops websites form doing such
things?

The claim was made that using ANY site one doesn't own will result in
having to agree to the same terms FB has. That is not true. As I
noted, SmugMug does not have any terms stating they have the right to
sub-license user's photos. That is the point I made.

Read SmugMug's terms of use. Nowhere does it state that they are
granted the right to sub-license their customer's images. It states
that the license the customer grants is for the purpose of them
providing the service the customer's pay for which is displaying the
images in their site. They state what the customer is granting them,
not stating something doesn't give them the license to do what they are
not stating..

Actually SmugMug is one of the better hosting sites, and provides
several different privacy levels. With the mp4 suggestion above, I was
making a tongue-in-cheek jest at some of the unnecessary paranoia for
what are mostly snapshots. Any photographer producing valuable,
saleable, copyrighted work is probably going to use an option giving
him/her more control and protection, leaving the social media sharing
for those images he/she is deliberately making public.

Most of my shots shared in various NGs usually contain full EXIF data.
and very often are GPS geotagged. What I do for those going to NGs is
use a metadata template to change "Creator" & "Copyright" to Savageduck.

...and all of those images I share online have a Creative Commons:
Attribute-NonCommercial-ShareAlike license.
<http://creativecommons.org/licenses/by-nc-sa/3.0/deed.en_US>

So if you check the metadata of this shot, you will find that it was
shot by Savageduck at Paso Robles Airport, with a D300S, and that
Savageduck is sharing it with a CC BY-NC-SA license.

If I had any photos that were worthy of sale then I would go a step
further than I do in how I use SmugMug. Until then, I really don't
worry that anyone would want my photos anyway. I don't post full-size
so if someone were to "steal" an image, it would have limited use to
them in that state.

Well, not quite. It depends on the words around those phrases as to what
it is you grant them. For example you could simply grant them the right
to store your photos on their computer and the right to make backups of
that storage. Or you could grant them the exclusive right to sell your
photos, and right to use could equally be modified.

No it gives them the rights that you enumerate. If you grant them the
right to do anything, then yes, they have the right to do anything.

Well, that may or may not be true. Since it is they that impose the
agreement, a court will in general interpret it in the most restrictive
way for them, since they were the ones that would have had the
opportunity to spell out the details. Those examples are somewhat
restrictive.

Not really. It is to an extent up to them to specify what their
agreement covers. But it is true that many are pretty broad.

No. You can allow that web site to show your photos under restricted

The problem is that their lawyers, in order to protect them, will try to
make the contract be as broad as possible. (In scinetific publishing for
example, may journals demand that you hand the copyright over to them)
But that does not mean that that broad permission is needed to do
certain things. Only permission to do those certain things is needed.

Again, false. You can allow them specific permissions. Eg to show your
photos in conjunction with advertisements.

Are you a lawyer?

SmugMug sets the terms of use that a customer agrees to, what court
would allow them to expand on what they specifically state you are
licensing them to do which is display your images on their site and
nothing more than that?

If the photo was a response to your ad, eventually you would have to
know where she lived.

You're not a lawyer then. But you'll ask me that question and then
proceed to give me your opinion as if it holds any more weight than
mine.

Not really. We could meet at a Starbucks.

But, I'm working on removing all EXIF information from all photos
as we speak ...

You haven't "waived copyright", you've granted them a nonexclusive
license to use your images in certain specific ways.

It is true that either examples or reasons do not necessarily limit the
rights granted. But it could well be used by the courts to limit those
rights if that example was written by the party that set the terms of
the contract. However, terms could be used which make it clear that the
example itself does not limit the breadth of the rights granted.
But that could be dependent of the specific judge.

By your logic, you are not qualified to have an opinion. You suffer

Oooops! Sorry, I see what you mean. I forgot I did not trim anything but
the troll group. I was trying to be too clever, deleting only the troll
group to fool him, but of course, he wouldn't have seen it without - or
until- he looks here. Ugh. My gaffe; sorry.

But ad images don't have EXIF data, right? I mean, we're talking about a
scenario where you take a picture of your dick in your bedroom with a
GPS-enabled camera, upload it to Flickr and Flickr (i.e. Yahoo) take that
image and use it to seel penis-enlargement pills by uploading it as an
advert on porn sites.

Now, it would be stupid and odd if that image still had your bedroom GPS
data embedded in it, but even if it did - it would still not be
Flickr/Yahoo using your *exif* data for nefarious purposes. They're
obviously using your private images for "nefarious" purposes, but that
purpose wouldn't be thwarted by you stripping your GPS/EXIF data. :)

Plus, your dick is on a porn site and used as example for penis
enlargement, congratulations man! :-D

Slightly personal, if she took it in her own living room which you may not
know she did.

Either way, it's hardly "intensly personal information".

This is the point where there is a difference. People talk, but you talk
as well. There is a _symmetry_ between the power and influence of talking
people and you. The talking people are also accessible, vulnerable and
susceptible to projection of your power. If someone badmouths you, you
can smack them, or worse. With institutions, be they some shadowy far-
away company or government agency, this symmetry does not exist. This
thread proves it all: we don't know what they do, and - more importantly
- we have no way of finding out. People don't talk anymore and you can't
smack anyone.

EXIF data, as inconspicuous as it is by itself, can be combined with
other data to produce a potent force. Crucially, this force may not be
directed to the photographer.

Say you are a modestly big company, drug lord or government agency and
you want to find someone. A dude is laying low and you want to beat him
up. In the old days, there was not much you could do except hope you run
into him on the street. But nowadays, with all the photos being snapped
and uploaded, you can use facial recognition programs to try to find the
person in question on a random photo, then use EXIF from that photo to
pinpoint the target in time and space. Ofcourse, in real life you
wouldn't scan photos looking for some dude, you would facial-recognition
scan *ALL* photos and store a table describing what faces are on which
photo. Then, you just look up the face you are interested in in the table
database.

The *CORE* problem with the scenario above is that only rich, powerful
and well-connected can mount such an attack. 200 years ago, there was no
fundamental difference between the power of a group of friends and a
state or company. All of our rules of conduct originated in that time.
But now, because of mass information, there is a huuuge difference
between the power of a group of friends and a state or company.

Unfortunately, this is so far the only real option.
