她发现,大多数人用的图形都只使用了最少的节点,即四个节点。与选择使用最多节点相比,这样做会大大降低安全系数。用户平均使用的节点数为五个,这意味着总共可以产生不到8000个可能的图形组合。但如果只使用四个节点,那么这个数字将会降到1624。
Ms Løge found that most people chose patterns that moved from left to right, making guessing combinations slightly easier.
洛格发现,多数人选择的图形都是从左向右移动,这样使猜到密码的难度又稍微降低了一些。
Men were more likely than women to choose long and complicated patterns, but interestingly there was little difference between the patterns chosen by right-handed and left-handed participants.
与女性相比,男性选择复杂的长密码的可能性更高。但是有趣的是,右撇子和左撇子用户创造的图形并未有很大不同。
‘Humans are predictable,’ Ms Løge told Ars. ‘We're seeing the same aspects used when creating a pattern locks [as are used in] pin codes and alphanumeric passwords.’
洛格告诉Ars Technica:“人们的行为很容易预测。不管是解锁图形密码、PIN码还是字母数字组合的密码,人们的设置习惯都是一样的。
She believes that using 'crossovers' to bamboozle onlookers and not starting from a corner produces the safest password patterns. Using a long and complex password is also unsurprisingly more secure.
