Novel Circuit Design Boosts Wearable Thermoelectric Generators

With Wearable Thermoelectric Generators, a continuous monitoring of the vital data is possible for athletes and patients. The difficulty is to supply the devices with power permanently. The Wearable Thermoelectric Generators with 40 mW of continuous power, which is worn along with the regular clothes, solves the problem.

Supported by Air Force Office of Scientific Research (AFOSR) and by PepsiCo, Inc., this research has paved a way to better understand the electronic and optical properties of polymer-based materials. A team of researchers from the Georgia Institute of Technology, under the leadership of Professor Shannon Yee, has developed a Wearable Thermoelectric Generators that is both light and flexible and uses the body's heat to generate electrical energy. The thermal generators were applied both to organic and inorganic substrates. However, the polymer variant achieves a significantly lower output power. The performance of the inorganic variant, on the other hand, was satisfactory, but the prototypes were rigid, comparatively heavy and therefore not usable.

The team of Georgia Institute of Technology around Professor Shannon Yee has now developed a Wearable Thermoelectric Generators method in which a p-type and n-type materials are each presented in a pasty form and on a fabric to be printed. The pastes penetrate through the meshes of the fabric and form a layer of Wearable Thermoelectric Generators about one hundred micrometers thick. As a result, several hundred thermoelectrically active points are formed in the combination of p- and n-conducting material on a specific surface of the fabric.

The structure of this Wearable Thermoelectric Generators is stable; it does not require additional ceramic substrates that absorb a large portion of the available thermal energy. Here, the fabric itself serves as the upper and lower substrate of the generator between which the inorganic thermoelectrically active materials are introduced; the Wearable Thermoelectric Generators are also flexible. In particular, the weight of the Wearable Thermoelectric Generators in comparison with other systems could be substantially reduced: to about 0.13 g / cm 2. A 10 x 10 cm² Wearable Thermoelectric Generators designed for the power supply of a "smart fabric" produces an output power of 40 mW from the temperature difference between the skin of the wearer and the environment. 

Pay with Google and Speed Through Checkout

Now shop easily on Android by using ‘Pay with Google’

If you love shopping online or offline shopping then dealing with cash will be a thing of past with availability of more and more mobile based payment options. Mobile based payment systems saw a surge in last couple of year with the launch of Apple Pay, Android Pay & Samsung Pay which brought the cashless future into reality. This was enabled by the launch and availability of the near-field communications in the modern smartphones. Google has announced that it will be launching very own way of paying on mobile devices with the ‘Pay With Google’ option. This will allows users to make use of their card to purchase any product or service using the application like Google Play, Chrome, Android Pay or Youtube.
 

Now pay easily on your Android devices

 
The ‘Pay With Google’ option will help in bringing together all the saved payment option within a single interface and it can be done by the app makers and retailers by implementing very few lines of code. Google has made use of the Google Payment API which made its debut during the I/O developer conference in May to give final shape and power the new payment method.

The aim behind ‘Pay with Google’ is to make the checkout process speedier for the users so that it can help in increasing the conversions for the retailers. This has been made possible by the tapping into any payment card of customer present in the file on Google rather than saving them onto the Android Pay specifically. This feature will also make it simpler for the users to shop on their Android devices using the Google powerful digital assistant called Google Assistant.
 

Google Wallet was Google’s first attempt

 
This isn’t the first time Google has forayed to make extensive use of the NFC-based systems. Just a while ago we had Google Wallet which was released in September 2011. Using the Google Wallet users were to make purchase online or even in the store as well as it can be used for sending money to the family and friends. During the initial phase this service found huge popularity and it was touted to leave the Apple Pay way behind in the adoption and active usage but sadly it didn’t happened.
 

A new era of and easy mobile transactions

 
During the launch Google official stated that facilitating payments will become a key capability for the user’s Google account through implementation of ‘Pay With Google’. This option will enable the users all across the globe to pay using their Google devices regardless of the device, platform or interface. Using the ‘Pay with Google’ feature at the checkout users will be presented with a list of payments cards already saved in their Google account. Users are simply required to give a click on the card they wish to use and Google will work towards sending the information right to the merchant along with the shipping address to facilitate the transaction instantaneously. More than 40 different payment providers had already partnered with Google to make the integration simple task for the merchants who wish to make use of this new feature.

Google Bug Bounty: Google Will Pay Hackers Who Find Flaws in Top Android Apps

Google’s new Security Reward Program

Google takes a lot of steps to ensure the security of their platforms. One such measure is the bug bounty reward program taken by Google. It involves the rewarding of persons who find faults or bugs in apps operating on Google play.

Google is closely collaborating with Hacker One, a company that rewards hackers for identifying bugs in a program and android apps to create a Google security reward program. This trademark initiative is said to help app developers and users alike. It will also improve the entire google play platform.

Bug bounty works like this, a hacker can identify bugs or an issue with a particular app and send a report pertaining to the issue to the developer of the app, the developer then resolves the issue/issues and then the hacker is free to contact the google play reward program.

The hacker can also work closely with the app developer to rectify the issue. The hacker can claim the bug bounty reward only once the issue is fixed. Hackers can get a bug bounty reward of up to 1000$.

There are various rules governing the bug bounty reward program. All hacker have to report vulnerabilities to the developers first. The developer should have resolved the issue before a hacker can request a bug bounty reward. If the developer does not respond to the bug report or does not show any inclination to fix the problem, the hacker does not get the bug bounty reward.

A detailed report has to be submitted along with meeting all of googles required criteria. Any issue that causes multiple problems in a program is only eligible for one bug bounty reward. If more than one hacker identifies an issue only the first report will be eligible for a bug bounty reward.

This program is right now available for only certain specific apps. Basically everyone knows that there are many apps on the play store and not all of them are up to a certain quality standard. In order to avoid giving bug bounty rewards to those apps that are sub- standard and contain a lot of bugs, google has introduced this program to only a few apps at present. Alibaba, dropbox, headspace, line,snapchat and tinder are the few apps that are included in the bug bounty reward program. As of now only these apps have opted into google’s bug bounty reward security program. In time a lot more apps mayopt in to the bug bounty rewards program.

Hackers will also be given information about the developer of the app so that they can interact directly with the developer in resolving the issue. Right now only google has reserved the right to reward hackers according to pre specified vulnerability criteria and only once the criteria has been met, only then will a hacker be rewarded. All bugs have to be resolved with a developer within 90 days to qualify for a bug bounty reward. Google has used the bug bounty program in order to improve the overall quality of apps and the google play platform.

Take Two for Samsung's Troubled Bixby Assistant

The next phase of Samsung Bixby is competitive AI market

Artificial Intelligence is seen as the new frontier which ought to be explored by every major tech firm in order to boost its array of products and services. Apple is already in the game, so is true for Microsoft, Google and Amazon and they had almost aced it then Samsung comes to the party and it fails miserably. Bixby assistant made its debut on the Samsung elite Galaxy S line-up with dedicated button. The major issue for it overcome is the presence of Google Assistant on the Android OS which simply removes the need of having another budding AI within a smartphone.

 

The failure of the Samsung in the first phase

 
Bixby assistant has a rough and trouble beginning since its launch with the Samsung Galaxy S8 where it was touted as next best feature to be present on the flagship device. Sadly this AI wasn’t even ready to take on the challenges of the English-speaking world therefore Korean giant Samsung has to disable it altogether. This saw the departure of the Bixby from the premium Galaxy device and a physical button was left in its wake to remind users of the Samsung debacle.
 

Bixby came back with new energy and promise

 
Last year’s recall of the Note 7 due to battery failure was nothing less a nightmare for the Samsung and this year’s failure of Bixby was another nail in its coffin. However Samsung engineer took the challenge of improving upon ten shortcoming of the Bixby assistant in a record time and they brought the Bixby 2.0 at the Samsung’s Developer’s Conference in Sans Francisco. It is worth noting that this time around Samsung has simply rebuilt the Bixby from the ground and this time around they are hopeful of making a genuine progress with their AI technology.
 

Samsung aims to conquer the AI market

 
Samsung has hired Dag Killatus who had earlier created the Viv assistant which got acquired by Samsung just a year ago and even before this he was core-member of the team which went on ti develop Siri. Samsung is a dominant player in the smartphone market with having over 23 percent of the market share which can help it in pushing and popularizing its personal assistant without much hassle.

Apart from the smartphones Samsung has planned to push Bixby assistant to the refrigerators and a number of other homely electronic devices as they can benefit immensely from voice-based controls rater than the user interface. Samsung is going all out to make the Bixby a better competitor in the crowded personal assistant by bringing Bixby more devices and it will also be opining it up for the third party-developers to boost its functionality and features.

As stated earlier Samsung Bixby Assistant will be competing against the Google Assistant majorly as it comes bundled on the Android OS. It is very unlikely that users will be keeping two different assistant on the same device but Samsung is keeping its finger crossed.

Google Advance Protection, for Those Who Need It Most

Google Advance protection: Secured Login Procedure

A much more secured login procedure for users who tend to be at high risk of online attacks has been designed by Google wherein the latest Google Advance protection feature is directed on defence against phishing, fraudulent access and accidental sharing of accounts.

This feature has been hosted for users keeping in mind journalist who would require safeguarding their sources or campaign staffers at the time of election. Google Advance protection program would be utilising Security Keys that tend to be small USB or wireless devices which would be essential in signing into accounts. According to Google they seem to be the most secured type of two-step verification, utilising public key cryptography together with digital signatures for confirmation on the identity of the user.

Google has stated that the security keys could be complex and could be utilised for users who do not mind taking them around, utilising the Chrome browsers on desktop and Google apps, since the keys would not function with the mail, calendar together with the contact apps of iPhone. Alphabets’ Google had mentioned that it would be rolling out this program to offer stronger mail security for users like government officials, political activists besides journalists who may be the object by refined hackers.

Google Advance protection with Physical USB Security Keys

Google users would have the advantage of choosing in to security settings focused on protecting Gmail, YouTube data and Google Drive from phishing attacks.Google Advance protection features comprises of physical USB security keys for connecting to a desktop computer before every login for the purpose of identifying the user.

Mobile logins would need a Bluetooth wireless device. Google Advance protection users would have their data confined from access by any of the non-Google third-party applications like the Apple iOS mail client aapl or Microsoft Outlook msft. The program is said to comprise of a much more laborious as well as detailed account recovery procedure in order to avert fraudulent access by the hackers who may tend to obtain access by playing that they have been locked out.

Users, who tend to be part of Google Advance protection, would have extra steps put in order, at the time of account recovery comprising of extra reviews together with request on why a user seemed to have lost access to their account. Moreover Google Advance protection feature tends to automatically restrict full access to Gmail as Google Drive for particular apps.

Google Advance protection: Upgrade Two-Factor Authentication Tool

As of now, Google Advance protection would be made available for consumers of Google Accounts and in order to offer comparable protection on G Suite Accounts, G suite admins would look into Security Key Enforcement together with OAuth apps whitelisting.

Earlier this year, Google had mentioned that it intends to upgrade its two-factor authentication tool after numerous high-profile hacks inclusive of the Gmail account of Clinton campaign chairman John Podesta in 2016. U.S. Intelligence agencies believed that those hacks comprising of a breach of John Podesta’s personal Gmail account had been done by Russian as part of a broader cyber campaign to assist Donald Trump, to win the White House.

Google has stated that it would update the security of accounts on a continuous basis which has been signed up for the program and the same is made available to users having a regular account. While Google had earlier supported the utilisation of security keys for two-factor authentication, Google Advance protection users would not be having backup log-in system available should they lose their keys other than the fuller account recovery procedure. Google has not specified what the recovery practice would involve.
