看的不是很懂，感觉很多专有名词，不知道具体是什么意思。文章主要讲了比特币是如何交易的，特别是关于malleability的方面。malleatbility是指signature改变一定程度下transaction不会改变。然后是有两个版本riginal和malleated，两个版本都能够交易，但是malleated会造成一个问题：比特币扣了但是没有记录。这个问题会被黑客攻击，比较麻烦。然后举了三个比特币交易网站的例子，一个是注意到这个问题然后解决了它，因此malleability分数高；另一个注意到了但没法解决，因为系统太复杂需要好几年时间来修复；最后一个直接无视掉了这个问题。最后两个例子都是得了零分

the google glasses can record the pin number
invisible-finger movements.
feature: less noticable than camera or cell phone
time 3 00:50
google glass can figure out the passcoade according to the fingertip. Therefore, scientist tries to make a program that can defend the shoulder surfing.
time 4 01:26
A new issue about security safety exists in car industry.
time 5 01:35
it will be hard to notice this issue. However, as long as new cars have more electronic control system, such as blutooth, self parking system, we will face
more security saftefy problem.
