Scientist at Binghamton University and Stevens Institute of Technology collected data sensors in wearable devices, such as smartwatch and fitness trackers using the algorithm. The goal is to open a gap to obtain a PIN or password.

Researchers conducted an experiment in (key-entry) as much as 5,000 times in 20 adults who use the keyword-based security systems, such as ATMs, for 11 months.

The result is very accurate with an accuracy rate of 80 percent on the first try, and 90 percent after the third attempt.

Researchers have little information recording until the slightest movement of the accelerometer, gyroscope, and magnometer that is in wearable devices without the need to pay attention to his pose.

Researchers consists of Assistant Professor of Computer Science, Yan Wang, followed by Chen Wang, Guo Xiaonan, and Bo Liu of Thomas J Watson School of Engineering and Applied Science at Binghamton University and Head of Research Yingying Chen of Stevens Institute of Technology.

They reveal, this is the first way that can reveal the PIN to exploit information from wearable devices without the need for contextual information

In internal attacks, hackers accessing wearable sensor devices worn on the wrist with malware. Malware will wait until the victim access security system with a password and sends back the sensor data.

In other attacks, hackers put a sniffer on the wireless security system to ‘eavesdrop’ sensor data that is sent to a Bluetooth mobile phone to the victim.

This study is fairly still at an early stage to understand the fragility of the security system of wearable devices.

Although they have yet to find a solution, the researchers suggest to the developers to inject some kind of ‘noise’ so that hackers can not read hand gestures. Developers are also advised to encrypt wearable devices and operating systems. “

This month, the company is headquartered in Cupertino that employ a security expert who was given the task of strengthening the security features in Apple products.

A guy named John Callas was the founder of several companies such as PGPCorp communications security, Silent Circle, and Blackphone. A spokesman for Apple reveal, Callas began to join Apple in May of this. Actually Callas was once worked at Apple in the 1990s and between 2009 and 2011. At that time, he designed an encryption system to protect data storage on a Macintosh computer.

Even so, Apple does not disclose details on what position Callas will work. Callas himself refused to comment on this.

Previously, Apple had an argument with the US government over whether the company should facilitate access of law enforcement in relation to encrypting customer information stored in iPhone devices.

In the case of the shooting in San Bernardino, Apple refused to cooperate with the FBI and the government. Finally, the government is authorized to use the services of third parties to dismantle the encryption Apple.

Both the FBI and law enforcement alike asked technology companies to help the government in an effort to catch criminals. In response, Apple and other technology companies said that the opening of the encryption efforts it will endanger the continuation of the product and makes it vulnerable to hacker attacks.

Meanwhile, unknown Callas was an opponent of coercion by the government to the company technology to unlock the encryption products.

Apple itself has previously said that the company will improve the security of its products, as was done by WhatsApp encrypt messages so that more private and closed.

9 Tips to Improve Performance Old iPhone

performance iphone

If you have not felt the need to replace your iPhone with the latest series that recently introduced, you are still ‘tinkering’ of your iPhone that performance was no less great than the latest series of iPhone. Here are 9 tips to improve the performance of the old iPhone.

1. Remove or reinstall an application that takes up a lot of disk space

First, if you’re not too often use an application, you can remove it. From all the applications you use frequently enough, there may be among them who have a lot of data that is actually not important.

By opening the tab usage (usage) in the general settings (general settings), you can see which applications are most frequently used. It seems clear that the application of photos, music, and podcasts takes up a lot of disk space. But the disk space consumed by applications, such as Facebook, Twitter, and Instagram maybe more.

From time to time, your iPhone might automatically perform “cleansing,” in which the cache (cache) of an application is removed. You can also proactively clean up the data that is not needed. Remove and then reinstall the application will make your iPhone back clean and empty shelf space.

2. Disable location services to applications that do not require GPS

Although you can enable features to geo tag your tweets on Twitter, disable access to most GPS applications can help the battery power and the speed of your iPhone.

In the iPhone menu, service location (Location Service) can be found in the privacy settings, you can choose which application uses GPS and how often an application is used. GPS is useful for maps, weather applications, and location-based apps such as Yelp. But you probably do not need to allow Dropbox to know where you are.

3. Reduce iOS animated features such as Parallax and increase contrast

The latest version of iOS has some interesting features such as Parallax, which makes shifting backdrop iPhone when you move your iPhone. But the aesthetic feature is not very useful.

Turning off these features will free up a bit of processing power and extend battery power. Simply go to the panel accessibility (accessibility) in the general settings, select ‘Reduce Movements’ or ‘Reduce Motion’. In the same menu, there is an option ‘Increase Contrast or “Increase Contrast’ which will take you to some of the graphic settings options.

4. Replace the casing

If you’re one of those people who simply ‘just wanted to’ taste of casing design Jony Ive third party, you may want to budget more money. Buying a new casing and use it on your iPhone much better.

5. Clean your photos and videos

The downside of a camera like the iPhone is a high-quality image capture of fast hard drives meet. So, diligent back up photos and videos, as well as remove them from your iPhone is a must, especially video, because video takes up a lot of space.

6. Turn off the ‘Background App Refresh’

If you frequently open many applications and do not close it again, the applications that might still be running, even if you do not use them. While you can close them one by one, the better you disable the “Background App Refresh,” which you can find in the general settings.

However, allowing a number of specific applications running in the background, such as Google Maps or Spotify, is also very useful. Disabling the application refreshment is not too make a big difference, but for the old iPhone, it’s worth a try.

7. Delete the old text messages

Although not exactly the same as removing and reinstalling an app, you can delete old text messages, which take up a large amount of storage space on your iPhone. If you do not want to do this yourself, you can also set the text message on your iPhone is removed after 30 days.

8. Restore

If you’ve tried everything, but keep your old phone does not increase quickly, maybe you should consider to restore it to its factory settings (factory reset, restore). Restore is likely to eliminate most of the complaints that you feel when you use your iPhone.

This step will really clean up, remove and reset the hard drive and RAM of your iPhone. However, please note, this step will not improve battery life.

9. Updating to iOS 9

Many users have reported that the IOS 9 newly released 16 of September, optimized for the iPhone older, and the size of 1.3GB file update to IOS 9 with 4.5 GB for iOS 8 necessarily indicate that the report was true.

In addition to freeing up more space, the new IOS also added features such as low power mode that saves battery power. In addition, the operating system also features ad-blocking (ads-blocking) that inhibits surfing speed, plus the ability to ensure application duplicates are combined into one.

Of course, there are still a number of uncertainties about the update older devices, especially devices as old as the iPhone 4S. If your phone is working properly, you may not need to perform this update.

Beware of your Mobile Security System

Hairford assess that the iPhone is a phone safest on the market. But the fact that the system could be compromised by the FBI, raises its own concerns.

“Apple device, or a Mac computer, never susceptible to PC viruses like most,” he said.

According to him, with a strong determination anyone can do anything. If someone has the ability to hack into the system, he will be able to do so anyway.

Hairford added, the average person in America rarely targeted. But in comparison to one thousand people, anyone can become one of them.

To secure the best possible mobile phone, Hairford advises users to take advantage of the numeric access codes, biometrics, or other.

“Do not rely on the security of the iPhone. Do not let someone take over your phone in any form,” said Hairford. He gives advice to avoid the use of Wi-Fi unnecessary in a public place.

In addition, notice any information stored in your phone. Instead, avoid storing highly confidential nature of the information on your phone.

Microsoft introduced a 3D communication via HoloLens

3D communication via HoloLens

For those of you who have seen the Star Wars movies may already be familiar with 3D hologram message that is sent through the droid R2-D2 or BB-8. On the other hand, maybe not a few who feel that communications technology is only in the film.

3D communication via HoloLens

However, today in fact one of the famous technology company, Microsoft, has successfully developed similar technology. Microsoft has just introduced a new communications technology called ‘Holoportation’.

Although no intact as in the movie Star Wars, this technology allows users to communicate with others via a 3D hologram technology. So, two people from different places can communicate directly and as if it were in the same place.

To do so, the project which was launched by Microsoft Research’s Interactive 3D, users should use the augmented reality HoloLens. Thus, the user will see a person in the form of a 3D hologram of the display in HoloLens.

In addition, to provide a better experience, Microsoft is also preparing completeness camera that allows users to see, hear, and interact with other people holograms in real-time.

Not just to communicate instantly, Holoportation also allows users to record conversations via hologram had to watch at a later time. In fact, users can also change the size of the hologram is displayed and adjusted as required.

Unfortunately, Microsoft has not revealed more information about the completeness of the camera used. However, some have referred to Microsoft’s technology is promising, because it is able to bring a new way of communicating that do not simply rely on video only.

In addition, although still in the development stage HoloLens Project Director Alex Kipman already using Holoportation for practical purposes. On one occasion, Kipman invite a NASA scientist Jeff Norris to talk about HoloLens of a separate place through technology Holoportation.

For your information, HoloLens is Microsoft’s augmented reality device that has been sold since March 20 last. However, for now Microsoft has introduced HoloLens aimed at the needs of application developers. At the inaugural device, Microsoft equip HoloLens with some programs, such as Holo Studio, Skype, and Holo Tour.

Sugar can be used as a source of battery power

source battery

Sugar has long been known as a sweetening foods or drinks, but recently a group of researchers managed to develop sugar for other purposes. Is a group of researchers from the Massachusetts Institute of Technology who is doing research for sugar used as a source of battery power.

source battery

Researchers use carbon nanotubes to heat the sugar and produce energy. As a result, the process proved to have similar outputs with battery commonly used in modern electronic devices, such as smartphones and tablets.

To do this, called The thermopower battery Wave (TPW) is using sugar to heat the heap nanotubes. After that, the results of this heat will push the tube in it and turn it into electricity as it is today.

In addition to sugar, the researchers predicted there are several other heat sources that can be used for more efficient than sugar. But from the calculation, the efficiency of the sugar in the battery in the trial had a value which is not far from the actual battery, which is up to about 1 percent.

In the test phase when the new TPW batteries used to charge the LED lights, but most likely this battery can change the future. In fact, this battery can be more useful than regular batteries for special purposes, such as charging the shuttles are eligible when space missions.

This is possible because in general the batteries can store up fuel will gradually lose power. Instead, the sugar will only be used when absolutely necessary, such as when the aircraft approached landing destination.

In addition, the use of battery-powered sugar can be designed according to the needs, such as for charging the wearable device. Not only that, the battery using this technology can also deliver power in large enough quantities when needed.

Note, however, this technology is still in the development stage and needs to be refined. One problem that needs to be resolved is access to sugar at any time when the main fuel is spent.
