Surprised to see my article float up again so many years later.
I wouldn't consider a mosaic + swirl to be fully secure either though, especially considering both of these operations may preserve the sum of all pixels, which may still be enough entropy to dictionary attack a small number of digits.
- jedberg 10mo agoIt's probably the least secure of the ones I mentioned, yes. But even so, it massively increases the search space for a dictionary attack because the attacker doesn't know which algorithm was applied first. But yes, at the end of the day, the best bet is to just take a mosaic of a random text and place it over the text you're trying to obscure. The reason people use mosaic is because it is more aesthetic than a black box, but there is no reason it has to be a mosaic of the actual text.
