1&2:Google glass poses a security threat. And the countermeasures are given to defend against it.

3.1:20s
The cars now with wireless connectivity and incar apps can be compromised remotely.

4 How do attackers control cars through incar app and it is a real problem we should pay attention.
5.ODM in smart phone make attackers steal your secret data.

1:45，google glass can be a tool for spy
55, countermeasure to shoulder surfing
1:00, automobile with more digital systems and embedded computers can be easily hacked
1:35, 3 steps to hack a car. Cars are susceptible to hacking because owners are reluctant to update software.
3:08, ODM on the phone can entail huge risk of illegal attack
Obstacle, transaction malleability can be used by attackers to stole customers’ money. DDOS attack used by bitstamp and BTC successfully stopped them.

Google glass poses a security threat; its camera and corresponding software can capture the movement of fingers accurately, although the test people stand far away from the camera.

Time3: 138; 1min38
In order to capture passcode, the camera must identify:1. the position and orientation of screen. 2.position of fingertips. YUE and others solved the problems.
2 ways to avoid capture:

Time4: 214; 2min18
As more and more digital devices(wifi, apps, disks) are embedded into cars, cars face security problems. And most cars lack security control system.

Time5: 276, 3min30
The intelligence device in cars: control brake and acceleration
Hack can attack cars by 3 steps
Some wireless devices make hack easier to attack; however, car companies need to design safe cars and update software.

Time6: 580, 6min29
Flaws of ODM can cause theft data in smartphones. Tests show that ODM can fully control phones. ODM can also reconfigure settings. The most of the world’s smartphones have such software package. ODM needs either a carrier’s infra or a base station to attack phones. Unlock phones are most secure phones. Flaws related to ODM can’t be fixed

1.definition of some terms :
Malleability n. 顺从；可锻性；展延性:The extent to which the signature can be changed before the change breaks validity in relation to the transaction
decrypt vt.破译；解释

TIMER 2:[2'10]
  critics about google glass(security threat)
  researchers-> video can recover passcodes(longer distance and undetectable way)

TIMER 3:[0'58]
  the way google glasses capture passcodes->footages+ fingertips
  solutions.

TIMER 4:[1'20]
  wireless+ in car apps->decline the security level.
  digital control system ->easy to hack.
  car companies don't pay attention to this problem.

TIMER 5:[1'37]
  researches on car security
  3 steps to attack a car.
  three aspects:1.car companies; 2.in-car applications; 3.designing security systems.

TIMER 6:[3'10]
  smart phones->easier to hack
  ODM.
  disadvantages about ODM.
  comparison between APPle and Andriod.
  will remain possible to hack ->until new techniques.

OBSTACLE:[5'06]
  to understand- first:define.
  relationship between malleabitily and transaction
  the way bitcorn-> real money and trans rate.
还讲了一些比特币的安全问题和出现问题时，B公司一些不合适的处理办法。。
不是很懂。。。

T2 2:34
Google glass can easily uncover the passcodes, even e-mail, by watching you taping.
An researcher suggest that many people are under that risk and google glass can do so in a long distance.
T3 1:33
The software need to identify the position and orientation of both the computer and user.
2 countermeasures.
T4 1:26
As more cars were installed digital systems, they are more prone to be hack.
The researchers made a magazine that rates the security of cars.
T5 2:04
3 steps that a hacker need to compromise the system of a car.
As the application rise, cars are under more risk.
A security method is necessary.
T6
ODM is under a great risk of being hack.
Andriod is most vulnerable.
Patches are not useful unless a new design is make.
This bug would be used by law enforcement or surveillance agencies.

Speaker: Virtual currency was on the ropes earlier this year. But Apple still will allow iOS developers to support
         the use of certain cyber coinage. One of the satellite TV providers also will encourage the use of bitcoin.
time2: 1min 50"
       Google Glass is criticised for easily stealing others' password and vedio footage.
time3: 50"
       After learning how the software capturing a passcode, researchers are currently testing ways to defend against
       such software-enhanced shoulder surfing.
time4: 1min 30"
       As the automotive industry has added more digital control systems and embedded computers, vehicles have become
       easier to hack.
time5: 1min 43"
       Other research groups have studied car security and demonstrated ways to take control of brakes, acceleration,
       and other functions. Car companies need to desigh their systems to detect exploitation attempts and prevent
       security from being compromised.
time6: 3min 49"
       A powerful remote-control system, ODM, installed on most smartphones could be used by hackers to secretly take
       control of many devices, allowing theft of data or eavesdropping on communications.
Obstacle: 9min 34"

the use of virtual currency
credit cards

time2
Google glass faces the criticism of security threat
many software developed now can steal the password from the user without using the camera
they steal the password through the movement of fingers
C has displayed the process to steal the password successfully from a people in short distance

time3
to capture a password, one should know the position or orientation of the device and the movement of fingers from users
to protect the users, one way to solve the problem is to disorder the keyboard and make the movement of fingers fails to connect with the information

time4
nowadays there are more and more people to have apps in their car
one research announces that the apps will lower the safety of the car and make it easier to attack
once you went to buy a car, the seller will tell you that the car in his shop is not vulnerable for attacking

time5
the attackers attack the vehicles from three aspects
the new development of security devices must make it more difficult to attack from these three ways
now the producer usually enhances the outlook of a car and also installs lots of apps in the car such as navigation function

time6
smartphone is much vulnerable to hacker because of the system ODM
it's much easier to steal the information in your phone than you thought
although the situation is crucial for ODM, they still can not solve the problem
the new patch cannot cope with the problem entirely
nowadays increasingly people would like to use xx to send messages or communicate with friends

obstacle(啊啊啊啊对这种科技文什么计算机啊电脑啊不感冒啊……看晕了)
introduction of the basic concepts
hash: disorder the information
malleability: ability without blend
signature: the scene of digital information
