Cyber Currencies Get Boost from High-Profile Endorsements
Virtual currency was on the ropes earlier this year. Bitcoin, the preeminent peer-to-peer online payment system, saw its value slashed by more than half after its largest exchange was hacked and shut down. Yet the fortunes of cryptocurrency have recently rebounded.

Apple used to block programs from its App Store that managed or otherwise dealt in bitcoin and its ilk. Now, though, Apple will allow iOS developers to support the use of certain cyber coinage. Apple has yet to say which of the dozens of cyber currencies out there it will now honor.

Meanwhile, satellite TV provider Dish Network will soon start letting its 14 million household subscribers pay their monthly bills using bitcoin. And rapper 50 Cent is accepting bitcoin as payment for his latest album. By the way, at this moment’s exchange rate, 50 Cent would also be known as 0.00075 Bitcoin. Not as catchy.

Such high-profile endorsements should help bring cyber tokens closer to the mainstream, even though there’s a risk that they’ll go down in value once you buy them. Still, U.S. consumers might be open to the idea. They’ve been hooked on a virtual currency for decades. It’s called credit cards.

time 2: 01:53
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.
time 6 03:46
smartphone also faced security issues.
the hacker can use the carriers infracture to communicate with phones or base stations.

The camera in the electrical devices such as smartphone may be automatically used to recover the passcodes of people. And a student, named Qinggang Yue, has already made an experiment to prove this.
2m16s

The student figure out a way to solve the problem that it is not east for the software to identify the position and orientation of a device's screen and the position of a person's fingertips tapping on it. However, there are some approaches that can defend agaist such software-enforced shoulder surfing
52s

Nowadays cars can be easily controlled.
1m16s

The details of how to control a car.
2m11s

The flaws discovered in the ODM can be easily used by hackers to take over the devices or reconfigure settings. And the author states views of many people to further illustrate the importance of the problem.
4m10s

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

Time2:2’24
  The passage tells us that Google Glass poses a security threat because it can stealing passwords or other data by watching someone at computer.

Time3:0’57
  The rationale of Google Glass to steal passwords is revealed.Some researchers are testing ways to defend against such software.

Time4:1’26
  The paragraph talks about that car security is likely to worsen as more digital control systems and embedded computers are added to vehicles.

Time5:2’08
  Some research groups have studied car security and demonstrated ways to control many functions. And it gives many suggestions to help car company and car owners to prevent security from being compromised.

Time6:4’00
  How hackers take control of many devices to steal data is revealed.And the capacity of different systems is different when attacked.

spk ; the fortunes of cryptocurrency have recently rebounded. APPLE used to block virtual currency, but now Apple will allow iOS developers to support the use of certain cyber coinage. US consumer will adapt this cybermoney because they were hooked on credit card for decades.a
spd :  1.37  0.40 Now researchers have shown that footage captured by the face-mounted camera could also pose a security threat. camera can capture the finger movement to identify the passcodes of user, even in a long distance.
       1.00 as the automative industry has added more digital cotrol system and embedded computers,vehicals have become easier to hack
       1.23 hacker only take three steps to remote execute your car. but prolific in-car apps and desktop-like features pose huge upcoming threats.
       2.53  ODM has some flaw backdoor which could be used to remotely install software on phones, or change settings without a user noticing.

Time 2 02:17.54
Wiht google glass, it's easy to steal password even SMS or email contents.

Time 3 00:55.93
How it works and how to defend from this.

Time 4 01:22.84
As more and more digital control add on, vehicles are easier to be hacked.

Time 5 01:58.78
explain details about how vehicles are vulnerable to be hacked.

Time 6 04:40.66
most phones can be hacked easy and give away info like data or being eavesdrop.
ODM installed in phones could be controlled and leak info.
Even with patch, attack through ODM is still possible.

Household pay their monthly bills using bitcoin.
help bring cyber tokens closer to the mainstream

SPEED:
Time2: 2:34
Main idea: the google glass can steal your passcodes
Structure:
footage captured by the face-mounted camera could also pose a security threat
The attack works by watching the movement of the fingers to work out what keys they are touching.
video footage can be used to recover passcodes at some distance.

Time3: 1:01
Structure:
the software must identify the position and orientation of a device’s screen as well as the position of a person’s fingertips tapping on it.
defend against such software-enhanced shoulder surfing.

Time4: 2:34
Main idea:
Car security is likely to be worsen
Structure:
more of them will be vulnerable to potentially dangerous hacking
vehicles have become easier to hack with digital system.

Time5: 1:58
Structure:
other research groups have studied car security and demonstrated ways to take control of brakes, acceleration, and other functions.
Attacks on automotive control systems involve three steps
Updating the software in a car means bringing the vehicle to a dealer for service

Time6: 4:23
Main idea: smartphone is easy to be remote control
Structure:
A powerful remote-control system installed on most smartphones could be used by hackers to secretly take control of many devices
Android devices were found to be most vulnerable
ODM will remain possible even after those patches are applied.
interest to law enforcement and surveillance agencies

OBSTACLE: 8:33
Main idea;Four headline events. Culprit: Transaction Malleability.
Structure:
Malleability-Hash-Signature
Transactions and Malleability
Transaction Malleablity score: 1/10
Distributed Denial of Service (DDoS) Attack---Transaction Malleablity score: 7/10
Bitcoin QT Wallet Client---Transaction Malleablity score: 0/10

two major problems toward this software
the researchers are now attempting new ways to defend against such software.

Time 4 - 1:17 - 214
With more digital controlled system added into the cars , some researchers have found that the vehicle will be more vulnerable to potentially dangerous hacking.

Time 5 - 1:42 - 276
three steps are involved to attack automotive control system
what the car companies should do to reduce such problems.

Time 6 - 3:47 - 580

Time2+Time3:03'44
Google glass, the camera climbed-on-face,can steal the password by recording the motion of your hand .
The counter action is to fluid the password.
Time4:01:57
Time5:02'37
Car become more and more velunrable while there is not the standard to measure the safe degree of car at all.
There are three steps to attack the car. The manufacture should advance the safe degree.
The app make the car stolen easily.
Time6:04'50
The phones which carry the ODM are easier open to attack.Apple &Andorid. More unclosed, easier be attacked.
The consequences are bad:1.steal the sensitive data.2. operate the app.
Even though you reset the mobile phone, the virus is still there. And there are some patches aimed at these attack point.
The problems could be of interest to law enforcement and surveillance agencies to intercept the messages.
