摘要
智能手机锁屏点阵的路径密码对手机的安全性非常重要,路径密码的数量是手机安全性的一个衡量指标。以矩阵运算工具软件Matlab为基础重点研究了3×3点阵的路径密码数量,有详细的程序支持。另外,为提高手机安全性必须增加路径密码的数量,但还要注意操作简单、符合大众习惯,为此推广分析了三种提高路径密码数量的办法:增加点阵阶数、用多条路径图案作为密码、允许重复使用每个连接点。
Path password lock screen smartphone dot on the safety of mobile phones is very important,path passwords phone number is a measure of safety indicators. Matlab matrix computation software tools focus on the basis of the number of lattice paths password, a detailed program support. In addition, to improve the safety of mobile phones have increased the number of paths password, but also pay attention to simple,consistent with the public habit, whereby promotion analyzed three ways to increase the number of paths Password： increased lattice order, with multiple paths pattern as a password, allowing re-use of each connection point.
