Keep your data safe with Android jelly bean 4.3

Android jelly bean 4.3 a one of the latest version of Android provided by google has many superior features. Google added five significant security features under the surface. Apart from that, Google has also added other two new features that work with any Android version being used now days.

Android jelly bean sandbox reinforced with SELinux:

Android jeely bean 4.3 includes SELinux now, a obligatory admittance manage (MAC) system in the Linux kernel to increase the exclusive recognition Number based application sandbox. Almost all apps with the Android sandbox makes them more secure.

Some users are cautious of SELinux, since the NSA had a large hand in creating it. Since SELinux, just like all of Linux, is open source that seems foolish to me. After all, the code is right in plain sight for anyone to look for security holes.

KeyChain enhancements:

You will be happy to know that Google has launched a new API that is named KeyChain API. This API enables applications to authenticate that system-wide keys are bound to a hardware cause of trust. So you don’t need to worry about the NSA snooping on your messages now. It indicates that OEM (Original Equipment Manufacturer) developers can add confidential keys that cannot be copied off the device, even if it’s or else absolutely compromised.

It will not stop the NSA -- or mainly most important Internet companies -- from using metadata, big data, and traffic analysis to remain an eye on you, but it will ultimately assist to stay the contents of your messages and apps protected.

Android Keystore Provider:

Android 4.3 also introduces a keystore provider and APIs that allow applications to generate exclusive-use keys, at the same time. It means that those apps can generate or accumulate confidential keys that cannot be seen by any other app. 

Increase your Visitors to your Facebook Page through Facebook Applications

What are the Facebook Applications?

Most of people are using Facebook for social network and for stay in touch with their friends and family. Do you know what Facebook Application is? Facebook Application is one of the important characteristic of facebook. People are crazy to use facebook cause of these applications. If you apply various facebook applications to your facebook fan page, user will enjoy that and you will have more followers to your page.

What is the role of Facebook Application in Visibility Increase process?

If you have more fans on Facebook, then it is easy to spread your services to the world. Add Facebook applications to your facebook page attractively to get more and more visitor to your page. You can add also flash games to have fun to your fans. You can have more options like RSS Feeds and all. 

Connectivity Between two social networking sites

Facebook Application has best feature which permits you to connect another social networking sites like Twitter, YouTube, Nutshell and other social sites. Because of this feature, you can reach to more and more visitors. If you connect this social sites to your facebook pag, Facebook will automatically share your post to another social networking sites.

Make attractive design of your page so you can have target visitors and you can have more business.

Sensitive E-skin for Robots

That day is not so far when robots will be touchy and feely like humans. Robots that made from metal in human size can do multiple works. These robots look same as human and can do different kind of work, these robots will have now skin that identify sensitivity of skins.

Because of this skin, now modern robots will look exactly like human and while touching them they will make us to feel same sensitivity and softness just like human being. Researchers of California University had tried to make sensitive fingers of robot that can pick up the delicate drinking glass carefully.

They also made e-skin for such robots from in organic materials. For this they used germanium/silicon nanowires on a cylindrical drum, which was then rolled onto a sticky substrate. This e-skin is one kind of chip which is slimmer like rubber and it make robot to feel touch. This robot can carry a child and play with him without any harassment.

The substrate used was a polyimide film, but the technique could be used with a variety of materials, including other plastics, paper or glass, the team said. The nanowires were deposited by the drum onto the substrate in an orderly fashion, and then the substrate was processed into thin, flexible sheets.

For the e-skin, the engineers printed the nanowires onto an 18-by-19 pixel square matrix measuring 7 centimeters on each side. Each pixel contained a transistor made up of hundreds of semiconductor nanowires. Nanowire transistors were then integrated with a pressure sensitive rubber on top to provide the sensing functionality.

The matrix required less than 5 volts of power to operate and maintained its robustness after being subjected to more than 2,000 bending cycles.

The e-skin developed by the team can detect pressure from 1 to 15 kilopascals. That's about the amount of pressure used to complete daily activities like typing on a keyboard or holding an object, the researchers said.

Such sensitivity is necessary to create a human prosthetic hand that can distinguish between the force necessary to, say, hold an egg without cracking it and the force necessary to lift a heavy pot without dropping it.
