This Tiny Computer Runs on Radio Waves Powered wirelessly & hasn't battery


wireless-power

No matter how smart and fast your devices would be, the biggest issue is always with the battery technology.


Whenever you go to buy any electronic gadget — smartphone, laptop, or any wearable — the most important specification isn’t its processor speed or its camera quality but its Battery Backup, which is not getting better any time soon.


What if you could eliminate the very thing entirely?


Well, that's exactly what the electrical engineers from the University of Washington has developed.


A team of researchers from the University of Washington’s Sensor Lab and the Delft University of Technology has developed a new gadget that doesn’t need a battery or any external power source to keep it powered; rather it works on radio waves.

So, this means you have to turn on your radio every time to keep this device charged. Right?


No, you don’t need to do this at all, because the device sucks radio waves out of the air and then converts them into electricity.


Wireless Identification and Sensing Platform

Wireless-Identification-Sensing-Platform
Dubbed Wireless Identification and Sensing Platform (WISP), the device is a combination sensor and computing chip that uses a standard off-the-shelf RFID (Radio Frequency Identification) reader to suck in radio waves and convert them into electricity.


Though the WISP is not designed to compete with the chips in your computer or even your smartphone, it has as much processing power as the Fitbit, which is enough to run sensors and transmit data.


The discovery could highly transform the Internet of Things (IoT) world as the WISP is even more low maintenance compared to Bluetooth Low Energy sensor chips being used today.


The next step in making the WISP usability even more convenient and easy is to create Wisent that would allow for wireless programming of the WISP. For this, the team has recently collaborated with the Delft University of Technology.

With the help of Wisent, the WISP can be programmed wirelessly and uses the very same radio waves to communicate.

"So far WISP required cables to reprogramme it, nullifying the advantage of battery-less-ness. Therefore, we present Wisent, a protocol that allows WISP to be reprogrammed wirelessly," said Przemysław Pawełczak, assistant professor at the TU Delft’s Embedded Software group.
"Our vision is to have truly wirelessly reprogrammable software-defined battery-less computers wherever and whenever we want."
For more details, you can head on to the research paper [PDF].

Though the ultimate aim of WISP is in fully realizing the Internet of Things and giving "dumb" objects some smartness, it might even find its way into smartphones as a sort of emergency backup calling module that works even when your phone’s battery is dead.


However, there is no detail on when the WISP will be made available for purchase, or how much it will cost.

Built-in VPN service in Chrome -here is how to get it



After Opera announcement of Free & Unlimited Built-in VPN with its latest or Updated Browser, Google also offer VPN service free with external ad-ons.

This is a great feature for current Opera users and once it's released in a public Opera build, it might even attract some new users. But you can already get unlimited free VPN service in the Chrome browser, and we'll show you how in this post.
In an age where your private browsing data is being hunted down by everyone from advertisers to hackers, VPN service is becoming more and more of a necessity. And no, the private browsing mode baked into your web browser isn't the same thing at all. VPN services can completely hide your identity from companies that try to track you and prevent them from building the online profile they so desperately want.
Of course, some people don't mind companies tracking them and for those people, VPN services aren't quite as essential most of the time.
Whether or not you want to guard your browsing with a VPN service all the time or only when the need arises, there's an easy way to add unlimited free VPN capabilities to Chrome. And the best part is that it's not complicated or convoluted at all. There are a few services that offer free VPN using a couple of different models, and our favorite among them is Betternet.
So how does it work? Simply visit this link from your Chrome browser and install Betternet's Chrome extension. That's it. You're done. You don't even have to register an account.
How is it possible that Betternet offers free VPN service while other companies charge for it? Check out this page on the company's site, which explains how it makes money. In a nutshell, Betternet offers an optional premium version and monetizes its mobile apps foriOS and Android, and that covers the company's operational costs. It's not trying to turn a profit with this service, so it hopes to maintain the same model indefinitely.
If you're not happy with Chrome and unlimited free VPN appeals to you, definitely give Opera a try. But if you'd rather stick with Chrome, Betternet is the way to go.

Opera Browsers Now Offers Free & Unlimited Built-in VPN service

INTRO:

Opera becomes the first web browser to offer a built-in Free, unlimited and 256-bit encrypted VPN service for everyone.


Opera's Free VPN protects unencrypted browser session from leaking on public WiFi networks and will also let unblock firewalls to improve privacy and security.


Detailed:

Virtual Private Networks (VPNs) have become an important tool not just for large companies, but also for individuals to improve web privacy, dodge content restrictions and counter growing threat of cyber attacks.


Opera has released an updated desktop version of its web browser with a Free built-in VPN service to keep you safe on the Internet with just a click.


That's a great deal!


For those unfamiliar, VPNs are easy security and privacy tools that route your Internet traffic through a distant connection, protecting your browsing, hiding your location data and accessing restricted resources.


Free VPN Service with Unlimited Data Usage


Unlike several other free VPN services, Opera's built-in free VPN service will offer you unlimited data usage as well. You just have to turn on a virtual switch in the Settings menu to enable the feature.


So you required to install no third-party extensions, pay no monthly fee as well as set no limit on data usage.

"By adding a free, unlimited VPN directly into the browser, no additional download or extensions from an unknown third-party provider are necessary," Opera's engineering chief Krystian Kolondra wrote in a blog post.
"So, today, our Opera desktop users get a handy way to boost their online privacy, as well as easier access to all their favorite online content no matter where they are."

Opera's Free VPN Offers 256-bit Encryption


Opera's Free VPN service uses 256-bit encryption to hide all your connection details and replaces your IP address with a virtual one, making it difficult for the government or anyone to trace your location, identify your computer or block content they do not want you to see.

The free VPN feature in Opera has been made possible after the company acquired VPN provider SurfEasy  last year.


Here's How to Try Opera's Free VPN


To give Opera's Free VPN a try, install the latest developer version of Opera for Windows and Mac, look for the 'Privacy & Security' tab and toggle this feature ON.


Since Operas Free VPN service is available in the latest developer version of Opera, the service lets you switch between three virtual locations: The United States, Canada, and Germany.


However, the company says it will add more countries in the stable version of its browser.

Google Steps forward to Secure its Web Store

Intro:
Chrome apps and extensions make things easier, but they can also do terrible things like spy on web users and collect their personal data.

But, now Google has updated its browser’s User Data Policy requiring all Chrome extension and app developers to disclose what data they collect.

Furthermore, developers are prohibited from collecting unnecessary browsing data and must also use encryption when handling sensitive information from users

Around 40 percent of all Google Chrome users have some kind of browser extensions, plugins or add-ons installed, but how safe are they?

The company plans to enforce developers starting this summer, to "ensure transparent use of the data in a way that is consistent with the wishes and expectations of users."

Google is making its Chrome Web Store safer for its users by forcing developers to disclose how they handle customers' data.

Google’s new User Data Policy will now force app developers, who use the Chrome Web Store to distribute their products, to be more transparent about their data collection practices.

In other words, the company wants its Chrome users to know what's happening when they use third-party apps and services that rely on its browser.

According to Google, "Protecting our users is our key priority, and we believe this change will make sure users are better informed and allow them to choose how their user data is handled."

Here's the list of new requirements for developers:


  • Be transparent about the handling of user's data and disclose privacy practices.
  • Post a privacy policy as well as use encryption for handling personal or sensitive information of users.
  • Ask users to consent to the collection of their personal or sensitive data via a prominent disclosure, when the use of the data is not related to a prominent feature.

Besides this, developers are also restricted from collecting user's Web browsing activity that is not at all required for their app's main functionality.

Google has already started notifying app developers about the change in its privacy policy and is giving them 3 months from now to comply.

From July 15, 2016, any app or extension that violates any of the requirements mentioned above will be discarded from the Chrome Web Store. So the only way to be restored will be to comply with the new policies.

Viber added End-to-End Encryption & PIN Protected Hidden Chats Features in Update



Viber, the popular mobile messaging app announced Tuesday that it has added full end-to-end encryption for video, voice and text message services for its millions of users.


Here, the end-to-end encryption means only you and the person you are communicating with can read the content, and nobody in between, not even the company and if court orders company to provide user data, they will get only the heaps of encrypted data.


Viber is the latest messaging platform to join WhatsAppTelegram, and Apple iMessage, who strengthened their default privacy features in recent times.


Founded in 2010 and acquired by Japanese e-commerce titan Rakuten for $900 Million in 2014, Viber is currently being used by more than 700 Million users globally across Android, iOS, Windows Phone, and desktop, the company claimed in a blog post published today.


The move comes just a couple of weeks after Facebook-owned Whatsapp messaging app implemented full end-to-end encryption by default for its one billion users.


Besides offering end-to-end encryption on all communication, the company will also provide a new PIN-protected hidden chat feature to help its users hide conversations from the main chat list, as well as Contact Authentication feature to verify contacts you're talking to.

All users need to update their app with the latest version of the company's software, Viber 6.0, take advantage of the features.Once installed, your Viber app will now show you a padlock in conversations to confirm that your one-to-one and group messages are end-to-end encrypted.

However, users will probably need to wait few weeks before everyone's app updates to add the new end-to-end encryption on Android and iOS.


In the wake of Apple’s months-long battle with the Federal Bureau of Investigation (FBI) over an iPhone used by a San Bernardino terrorist, it seems like end-to-end encryption has become a trend and you’ll continue to see this in more applications and services.
