The National Institute of Informatics (NII) in Japan claims that taking and publishing photos of subjects who are flashing the popular two-fingered 'V' or peace sign could lead to identify theft. It warns that fingerprint recognition technology is now so advanced that even casual snapshots can be used to retrieve fingerprint information. The report also says the technology is widely available and easy to use.

Does that show GPS?
OK, from now I will only give the one finger salute.
Yes.
You can modify or delete.
A few years back I was using a phone and hadn’t gone through settings to turn off gps.
Discovered my mistake and used a batch command to remove gps from the photos.
It is my understanding that the GPS meta data is not with the photo settings and related data.
When I looked at the photos a few days ago, I saw nothing but the GPS data version. Not convinced, I downloaded a Linux command line tool for batch processing. Found that the data was in fact not on my photos.
Over the years, I’ve become much more concerned about this type of issue. Technology can be used for good or bad. It is so prevalent that it is frightening.
Found it, here it is, the command line tool that I used years ago to clean up image data in windows. It’s “Jhead” http://www.sentex.net/~mwandel/jhead/usage.html
Mechanic’s gloves are cheap at local parts houses.
Fake news.
No way are lighting levels sufficient to illuminate whorls on the finger in any normal photo.
lesson for peace sign flashers: don’t do that
That is amazing.
A certain amount of resolution is needed. The casual photo just won’t do it.
Then the camera would get the fingernail.

NOT the one over your shoulder.......
Any picture taken of Japanese kids will include lots of peace signs. It is like they are hard-wired for it. Camera? Smile and flash peace sign, so no wonder the Japanese are concerned.
According to Adam, nothing...
The resolution of the iPhone 7's wide-angle camera is approximately 4600x2600 pixels with a field-of-view of about 63 degrees width; this translates to an angular resolution of about 240 microradians per pixel.
It's surprisingly difficult to find hard numbers giving the distance between fingerprint ridges and grooves, but I was able to come up with a estimate of 0.05 mm (50 microns) for the closest spacing after some looking.
At one meter distance, this is 50000 microradians per pixel, which means that at distance of one meter, the iPhone wide-angle camera can put almost 210 pixels on each pair of ridges!
This makes the article's claim believable, although getting enough contrast on a fingertip to pick up individual ridges and grooves is questionable; with optical contrast only (no ink or surface-contact effects) a great deal of dynamic range would be required to obtain a fingerprint of sufficient quality to do personal identification.
Still, it's only a matter of time before this is possible.
Sorry, that calculation was way off. When I looked at my write-up on the screen, it just didn’t look right.
Looks like I’m off by a factor of a thousand (swapped meters for millimeters at one point).
It’s actually 0.21 pixels per ridge spacing at one meter, which puts it out of reach of the iPhone 7 camera. Way out of reach, even if you don’t count the dynamic range issue.
I should have double-checked.

But what about your FACE? HAHAHA
So when playing Rock Paper Scissors, never do Scissors.
If they can get a crystal clear picture of finger prints then why the heck can’t they get half decent not so blurry youtubes?
Today it’s finger prints and facial recognition, tomorrow it’s irises. Might as well submit to burkas.
