Cell Phone Hackers can clone your cell phone from posted photos

Comment: Share this with everyone you know! Did you know that posting a screenshot
of your cellphone on Facebook leave you open to be a victim of IDENTITY
THEFT? Every cell phone has a graphic signature embedded in the pixels
that can be easily deciphered by hackers with a simple computer program. A
screenshot like the one pictured can yield a person's location
information, phone number and unique SIM card ID number. It's this last
bit of information that can allow hackers to easily CLONE YOUR PHONE and
then monitor all your text messages, numbers and addresses in your contact
list, and even any credit or bank transactions you make from that phone.
If you know someone who is posting screenshots of their cell phone,
forward this to them and warn them to STOP NOW.

I have no idea if cell phone cameras actually do that. Most digital cameras do add certain meta-data to the image file. Date and time are common, location is possible if the device has GPS. You can easily see the meta-data though (in windows just right click on the image and "properties" then "details") and it can be easily edited or deleted.

I do know that many laser printers encode the serial number of the printer in tiny yellow dots on every page of output.

So it would certainly be possible to do something similar with an image file.

Even if it were true that cellphones use pixel steganography, a screenshot will usually be a .PNG, Facebook converts to .JPG, so precise pixel values would be altered, and so the information would be lost.

Screenshots from my iPhone contain no data about the phone itself. Even photos taken with the phone contain only basic data on the device.

And you were so kind as to give use the program and instructions so that we might verify it for our selves. NOT!

I could not see any cell phone company assuming they did imbed information into the picture, using anything more than the phone's serial number.

Okay, Wayne (or is it Garth?)...

Most of the data will also show up under file properties/details, or "get info" on a Mac.

OP said the information was imbedded in the pixels , not as metadata within the file.

ETA: It looks like some bad wording. My first post should have more clearly referred to the OP, not yours.

I think Wolf333 was nearly responding to this:

Which is what I take he was backing up when Singing in the Drizzle was asking for proof.

There's plenty of space besides in the pixels and the explicit metadata to hide stuff in a jpg.
