Relevant: A friend of mine analyzed lock patterns for her thesis. Got some press: https://arstechnica.com/security/2015/08/new-data-uncovers-the-surprising-predictability-of-android-lock-patterns/ https://arstechnica.com/security/2015/08/new-data-uncovers-t...
The patterns are predictable, and can be further narrowed down if you now the hand they normally use.
- dafrankenstein2 10y agoher findings that females are more likely to use simple patterns is interesting..haha
- pbhjpbhj 10y agoThat surely is an interesting finding, especially if it can be confirmed. Null hypothesis: females in general are more trusting and [consider themselves more] trustworthy. As humans we tend to project our own morality on to others, thus expecting people to be less likely to try and attack their stuff and so being less desirous of strong protection?
- idanoeman 10y agoWouldn't the null hypothesis be no gender difference, with gender difference in either direction to be proven by experiment?
- pbhjpbhj 10y agoWe're using alternate definitions: I'm using "my null hypothesis", as in my zero-numbered hypothesis that I would then attempt to test for. You're using, presumably "the Null Hypothesis" as a specific hypothesis suggesting that two populations have no causal relationship [IIRC]. My null-ordered labelling just confused my hypothesis with a particular default used in some statisitical arenas AFAICT.
- AnimalMuppet 10y agoidanoeman's use of "null hypothesis" is far more standard than yours. And if you use such a phrase in a highly non-standard way, you can't be surprised that people think it means something other than what you meant...
- kevindqc 10y agohow come length 8 and 9 have the same number of combinations?
- allenz 10y agoThere is a one-to-one correspondence between them: a length 9 combination is just a length 8 combination followed by the sole remaining node. The lock screen has 9 nodes.
- harperlee 10y agoI reduce predictability - and people peeking - by passing over already selected nodes and deactivating the visual tracing of the graph. I can draw my code before someone several times without they being able to unlock my phone :)
