【开元888官网】多数人的手机锁屏图形不安全

We all know that passwords such as ‘12345 and ‘password1 are far from secure, but how about your lock screen pattern for your smartphone? A study shows that most of us use similar patterns to unlock our handsets, meaning they could be easily guessed by criminals.我们都告诉，“12345”或“password1”这样的密码十分不安全性，但是你用于的智能手机的锁屏图形安全性又如何呢？一项研究表明，我们多数人都会用于相近的图形来关卡手机。这就意味著，关卡图形很更容易地就不会被犯罪分子猜中到。More than three quarters of people start their lock screen patterns from a corner, according to the researcher behind the worrying work. Marte Lge, a graduate of the Norwegian University of Science and Technology, also said 44 per cent of study participants start their Android lock screen pattern password from the top left corner. 这项谓之人忧虑的研究背后的研究人员称之为，多达四分之三的手机用户所用于的锁屏图形从四个边角之一开始。

挪威理工大学（Norwegian University of Science and Technology）的研究生马尔特·洛格还回应，在所有研究参与者中，有44%的人为自己的安卓手机设置的锁屏图形“密码”都从左上角开始。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 users 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报导，洛格找到，约10%的关卡图形不会包含一个字母，比如N或C。多数时候，这些字母都与用户自己或疏远的人的名字对应。

安卓图形关卡于2008年发售。上周，洛格在拉斯维加斯举办的密码保护研讨会（PasswordCon）展出了自己针对安卓手机的图形关卡的研究成果。Ms Lge 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.洛格在其论文中采样了4000个用户自创的安卓关卡图形。

她拒绝研究参与者建构出有三个安卓锁住屏图形——一个用作一款虚构的购物应用于，一个用作一款虚构的银行应用于，一个用作关卡手机。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.她找到，大多数人用的图形都只用于了最多的节点，即四个节点。与自由选择用于最多节点比起，这样做到不会大大降低安全系数。

用户平均值用于的节点数为五个，这意味著总共可以产生将近8000个有可能的图形人组。但如果只用于四个节点，那么这个数字将不会降至1624。

Ms Lge found that most people chose patterns that moved from left to right, making guessing combinations slightly easier.洛格找到，多数人自由选择的图形都就是指左向右移动，这样使知道密码的可玩性又略为减少了一些。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.与女性比起，男性自由选择简单的长密码的可能性更高。但是有意思的是，右撇子和左撇子用户建构的图形未有相当大有所不同。‘Humans are predictable, Ms Lge told Ars. ‘Were seeing the same aspects used when creating a pattern locks [as are used in] pin codes and alphanumeric passwords.洛格告诉他Ars Technica：“人们的不道德很更容易预测。

不管是关卡图形密码、PIN码还是字母数字人组的密码，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.她指出，用于“交叉”图形欺骗“盼的”旁观者以及不从边角开始绘制图形可以设置出有最安全性的密码图形。

意料之中的是，用于简单的长密码也更加可信。
