I had a lot of fun coming up with a design for these explanatory illustrations for the datasec startup,
mylens.io The ideas they initially gave me were full of forced analogies, and I opted for something much simpler and straightforward instead. Data is already an abstract concept, there's nothing gained by shoehorning it into an analogy.
The other main concepts- safety, restricted access - I thought best to keep as close to a direct representation as possible. And this is what I came up with!
