Some quick terminology:
- The information in each line below is arranged in something called a “key-value pair”. A key can be thought of as a ’title’ for some data. And the value is the actual data attached to a title. For example, the key in the first line below is “File name” and the value would be something like “my-picture.jpeg”, though in this case it’s been redacted.

Bonus questions#
Some bonus questions for you, since you made it all the way to the end:
- How many of the above values do you think remain the same across all the photos you’ve taken on your current phone?
- For all values which remain the same, how many other phones do you think produce that exact same combination of values?
(The answers are “many” and “not many, if any”, respectively.)
