    Wonder if this will ever be used in a court case?

    That's what i thought but then couldn't think of a situation where you'd need to prove what phone took a picture.

    I thought this was the case already? Similar to how printers embed a digital watermark in each sheet printed?

    or slightly more negative: determining who the whistle blower is.... eek!

    flickr.com has been doing this for years. they can tell you all you need to know about what and who took the photo.

    Re: Scientists can match photos to individual smartphones

    Surely things like JPEG compression will destroy much of the data. How many real use cases could there be (particularly on social media) where an image hasn't been crushed to oblivion? Surely if the eye can see the degradation then a computer is going to be hard pressed to find a 'digital signature'.

    Re: Scientists can match photos to individual smartphones

    This research is using photos of a known QR code, which is a long way from determining which phone was used to video something illegal

    That's just metadata, so basic model info and sometimes GPS location - that kind of thing. This is identifying which iphone 6 took a given photo, out of all the iphone 6's sold (or at least the 30 they looked at)

    No use for tracking down the source of a JPG though.
