反黑键盘

我们曾介绍过让键盘消失的掌箍设备,学习每个人不同的打字模式,最终达到不使用键盘就能打字的效果。今天介绍的产品身上,不难看到乔治亚理工学院的研究者也是利用了「一千个人有一千种打字习惯」这个道理。

在黑客横行的时代,密码实在是当今社会上最危险的保护方式了。

以 Zhong Lin Wang 教授、 Jun Chen 为首的乔治亚理工学院 (Georgia Institute of Technology) 研究员创造出的一款键盘,能够通过不同人的打字方式进行键盘加密,前所未闻有没有。

不同的人在敲击键盘按键之间的时间停顿以及对每个按钮附加的压力都不同。我能说以前见过英国《泰晤士报》的编辑打字像战斗机般地急切而热烈吗?为了证明这个理论更加靠谱,研究者还让 104 个人用键盘打出四个「touch」,发现每个人的打字模式都能被很好地区分开来。

怎么做到的?键盘上覆盖了四个叠加透明层,其中最上层的 FEP 塑料用于收集使用者打字时指尖产生的静电,利用摩电效应产生电力。另外两层氧化铟锡 (下演示图中黄色)则起到电极的功能。中间 (显示红色)的一层是 PET 塑料,用的是和我们喝水水瓶的相同材料。想要了解得更精钻请戳此看论文

这个特殊的结构能让使用者每次敲击键盘都产生一种独特的电信号,分析后使用能够作为区别使用者的信号。

除此之外,这个键盘完全做到「自力更生」,支持自我供电。利用啥?不用猜都知道,当然是人们打字产生的能量啦。这股能量能够实现键盘不带充电的无线蓝牙操作,甚至还能为一些需电较少的设备充电呢。又是一个「1+充电」模式,可这个 1 的技术含量明显比以前都要高。

最后再让你 YY 一下,研究者放话,就算把咖啡倒在上面键盘都玩不坏。因为它上面覆盖着塑料呀。小记就期待采用塑料也能够让将来产品上市价格更能让老百姓接受吧么么哒。
