The US government has known this forever. Ever see those black boxes over censored documents? It's obviously better than blurring, the only information you get is the size of the box.

Actually, quite a few times in the past with that method, you've gotten the complete text, because someone uses a format that includes the text as text (like PDF) and then dropped a solid-black box over the text, which looks like the text is obliterated, but preserves the entire content in the file.
- Namrog84 10y agoOne time in college. A teacher did something like this with hw and solutions being "hidden"/"censored". And I was easily able to get around it and have all the solutions :/
- taneq 10y agoOne of our lecturers did something similar, but with class grades. They started from a complete list of grades in Excel, and for each student, deleted all grades but that student's grades and then saved a copy. Unfortunately, they did this without disabling the Excel feature that saved undo data in the file, so anyone in the class was able to hit Ctrl+Z a couple of times and see the entire list of grades.
