Combination Lock Crack

This is an attempt at using mathematical inference to crack (bike) lock combinations. The key idea is that as humans, we tend to believe that when we shuffle, we shuffle “randomly”. I.e., we think that as we're sporadically shifting the digits on the lock up and down, all possible combinations of numbers are likely to happen with the same probability.

With this project, I was able to prove that we're definitely wrong: we do not shuffle randomly. I was able to exploit that idea using mathematical inference to try to crack my code in a safe way. Essentially, all I did was record 20 hand-shuffled digits on my bike and apply mathematical inference models on those recordings. I was able to find my digits within the top possible results.
