She found that around 10 per cent of patterns create a letter, such as an N or C, which more often than not corresponded to a user's own name, or that of a loved one, Ars Technica reported. She presented her findings into Android lock patterns, which were introduced in 2008, at PasswordCon in Las Vegas last week.
据科技博客媒体Ars Technica报道,洛格发现,大约10%的解锁图形会构成一个字母,比如N或C。多数时候,这些字母都与用户自己或亲近的人的名字对应。安卓图形解锁于2008年推出。上周,洛格在拉斯维加斯举行的密码保护研讨会(PasswordCon)展示了自己针对安卓手机的图形解锁的研究成果。
Ms Løge sampled 4,000 user-generated Android lock patterns as part of her thesis. She asked study participants to create three Android lock patterns – one for an imaginary shopping app, another for a fake banking app and one to unlock a phone.
洛格在其论文中取样了4000个用户自创的安卓解锁图形。她要求研究参与者创造出三个安卓锁屏图形——一个用于一款虚构的购物应用,一个用于一款虚构的银行应用,一个用于解锁手机。
She found that most people chose to create a pattern that travelled through the minimum amount of nodes of spots – four – making their pattern much less secure than if they opted for the maximum number of nodes. The average number of nodes used was five, meaning there were less than 8,000 possible pattern combinations, but this dropped to just 1,624 for four node patterns.
