My phone has this as an option to lock my phone. At first it seemed like a good idea, you get nine dots and have to draw a pattern that is 4-9 dots long.
However looking into it, there are only 389112 possible patterns. Couldn’t that be cracked with a conventional computer pretty easily?
Not only that, but looking online the majority of Alps are only 4 or 5 dots long, and about 77% start at a corner. There are less than 9000 patterns using 4-5 dots, and only 44% can start at a corner.
Even worse, about 44% start at the top left node. So doesn’t that mean that about a third of these locks are using less than 1000 possible combination?
I don’t know if this post sounds like I’m trying to break into someone else’s phone, I’m curious to stop others from getting into mine.
Point is, are these locks worth anything if a person really wants to get into. Your phone and they are savvy? Wouldn’t a laptop alone be enough to try all 389112 patterns (but again, most people are selecting from less than 9000 patterns, which is even easier to craxk)?
