Да хуй его знает. Тут
https://en.wikipedia.org/wiki/Exif пишут про ИД девайса:
"Since the Exif tag contains metadata about the photo, it can pose a privacy problem. For example, a photo taken with a GPS-enabled camera can reveal the exact location and time it was taken, and the unique ID number of the device - this is all done by default - often without the user's knowledge. Many users may be unaware that their photos are tagged by default in this manner, or that specialist software may be required to remove the Exif tag before publishing. For example, a whistleblower, journalist or political dissident relying on the protection of anonymity to allow them to report malfeasance by a corporate entity, criminal, or government may therefore find their safety compromised by this default data collection.
In December 2012, anti-virus programmer John McAfee was arrested in Guatemala while fleeing from alleged persecution[15] in Belize, which shares a border. Vice magazine had published an exclusive interview on their website with McAfee "on the run"[16] that included a photo of McAfee with a Vice reporter taken with a phone that had geotagged the image.[17] The photo's metadata included GPS coordinates locating McAfee in Guatemala, and he was captured two days later.[18]
According to documents leaked by Edward Snowden, the NSA is targeting Exif information under the XKeyscore program.[19]
The privacy problem of Exif data can be avoided by removing the Exif data using a metadata removal tool.[20]"
