Extract from Chris Dale's article "Non-conventional data sources and the crossover between litigation disclosure and privacy

Given a slot at last week’s Masters Conference in London, I chose to use it to talk about the sources of data which might easily be overlooked when giving or receiving data for disclosure / discovery. My subjects ranged from the metadata and EXIF data in photographs, to Google Maps tracking, to the Internet of things and social media.

I will do a post or a video on that in due course, but this article is about related subjects which have turned up since I prepared that talk – only last Thursday.

iOS gives access to photograph metadata

The first was an article in The Register called iOS apps can read metadata revealing user’s location histories, with the subtitle Access through a gift shop full of personal data. “EXIF” stands for Exchangeable Image File, and is a standard format for data ancillary to multimedia files.

Most of us have come across apps which ask for permission to access the pictures in our photo libraries. There is often good reason for this – if I want to send one of my pictures to Twitter or Facebook then those apps must have permission to access the image store. iOS 11, it seems, captures more than just the photograph, and hauls in the location data and other information stored with the image. This may or may not matter to you but it seems important to know.

In opening my talk last week I asked for a show of hands from those who kept location services on. Most did. My supplementary question was “Do you know whether or not you have location services turned on?”. That served as the premise for the part of my talk which related to the amount of location history which may be available on phones – and therefore available to be considered for relevance on disclosure / discovery.
