suddenly imaginable, i might the most efficient and make it a dream of revolution. thoughts, july 20th, dw. what do you want to pay for your groceries or coffee with your face? that seems pretty convenient. but is it secure? lauren: this in a moment, also on the show families of victims of us school shooting, assuming a gaming company on the social media platform. and he waves all scorching the globe tech might help us talk well the problem will show you the latest development. these other topics that i'm moving the tech world have you ever paid in a shop simply by showing your face? chances are that you will suit biometric payments on the rise. research has full cost of a $3.00 trillion us dollars worth of biometric payments next year. and lots of those payments will come from phase scans and

a shop for restaurants. but is it safe? what happens to the data? and could i charge my sisters credit card instead of mine? if you haven't done it yourself, you've most likely seen some on unlock the phone with that face. apple for example, already offers the circles based. i think it works just like a fingerprint scanner on a phone. except that your face is your biometric identification, put chinese financial service provider pay has push this to the next level payment by showing your face only. you don't need to present a bank card. oh, so you're saying a now big financial players like jp morgan and mazda cod? pushing pay by stays as well as online giants like amazon is expected. that within the next is more and more pay by face systems will be established. how does it work? well, it's very simple. first you capture your biometrics by activating your camera or even with a simple sophie. the face is then broken down into data points which is stored and

so called token. so there is no photo of the stored on a server somewhat. the tokens are enough to identify your face, then you need to connect your face data to your bank account or credit card. if you are in a store or restaurant that supports pay by face, you simply press a button on the payments, having on the device, scans your face, and what you just paid with your face. meaning you've gone to the restaurant permission to debit the payment from your bank account. is it secure? biometric authentication is a much safer technology than passwords or pins. a face scan is also also chosen other biometrics, like a fingerprint, according to manufacturer. as a face, comedy has like a password. the systems also have extra security layers, and that will con, be easily tricked by a photo of person or even by mosque. the technology isn't perfect though. it's not recommended for children under the team, because the facial features may not be fully developed. and how about people that look just like the sibling, say twins with a twin,

be able to use their own face to make payments, and the siblings name without the knowledge? well, pay by face companies at least combo but outs. if you have a twin, i'm not concerned about them using your account. without your authorization, you should immediately set a custom pin after you create your pop id account. that's what phase payment service pop id sets. but what is the catch? as often your comedians comes with the exposure of your data by magic tokens, make it not charge for criminals to hacked your accounts. but security active as a warning, the biometrics theft is becoming more common placed. there is even more to consider some political regimes try to track and identify people using facial recognition systems in order to identify say, protested they need a data base to compare the data to. so they could be very interested and you'll pay by face data and even low tech companies assure us that our data is encrypted and still securely. we have seen companies hand out data to governments before. so

definitely make sure that you trust any company. you use this technology with the 2 big names in tech, a being sued over the alleged role in the us school shooting one is activision, the company that makes the 1st person shooter games cool of duty for you is the player. use a weapon yourself and the game. this ego perspective is what gives the genre it's name ego. shoot to the other is meant to parent company of instagram on facebook. families of victims are choosing the tech funds of collaborating with the fire arms industry. the claim, the best some responsibility for the shooting is what you need to know. in may 20, 2218 year old salvador ramos, a former student, a rock elementary school, say to they show 19 students and 2 teachers. 17 others were injured, but survived. ramos was shot on site by police officers. this tragic incident re ignited heated discussions about american gun culture and violence. now families of

the victims claim that gaming company, activision, and social media company, meta bass, some responsibility in a separate law suit. they also swing fire manufacturer a daniel defense which made the rifle used in the shooting. in diamond reeves over the last 15 years, 2 of america's largest technology companies have collaborated with the fi um the district. that's the serious accusation. isn't that promoting guns and do egos shooters to and getting those into tell us? well, the scientific verdicts on the last not to is rather clear, that is no causal link between playing video games and gun violence in real life. that's according to a majority of scientists and a recent review of 82 medical research articles on the topics drew the same conclusion. but the plaintiff, i'm not targeting this link between gaming and violence, they are targeting a special feature of color due to what the weapons in the game mimic real life weapons. basically,

they are claiming the games to just pay us how to handle firearms. then diamond states, but even though killing is parts of many games, the look sale of the guns and cool of duty is extremely realistic. backups people, especially young ones, interested in buying real weapons. the fictional weapon in the game called of j t called m for a one, is strongly based on existing a off of the models. the sheer to solve with a ramos use such a weapon and you've all the, and a off of things have also been involved. and 10 of the us is 17 dead list. my shootings since 2012 and other titles of the cool of daisy franchise activism. actually had licensing deals with gun manufacturer as a use real gun names of the legal problems they decided to work with lookalikes for the plaintiff. that is simply not good enough. they've made some serious allegations. the defendants bear responsibility for this profound corruption of our children in concert with certain file manufacturer as they have groomed a generation of young man who

a socially vulnerable and secure about the masculinity and eager to show strength on a set dominance. defendants have spent years positioning the counterparts and the gun industry as the answer to those problems. the summit up the trial is not about the question of why the 1st person, shooter games incite violence, but about where the coolant unity is promoting. guns. teaching people how to handle them, selling guns by social media. the accusations against metal a similar met the social media of instagram office by all manufacturer. it's something even cool of juicy cut off. on the supervisor's child to speak directly to mind those in the home of school, even in the middle of the night, according to the law says you've all the shooter was talking to the instagram via daniel defense lessons manufacturer that produces a all 15 bicycles. daniel defense is also being sued by the plaintiff, because officially, guns sales also been an unmet. in reality, the company discloses little information about how it enforces that an

investigation by the washington post even revealed the guns buyers and sellers on facebook to violate the rules. 10 times before they got kicked off a tougher match match, as in sufficient regulation of his ad info system has been heavily criticized. but yet it's hard to predict how all of this will play out in court. but what do you think of these valid arguments? let us know your opinion. fucking bucket these days. you're not alone. he way of us got shame the glove this year. that's already been reco, breaking temperatures in india, mexico and more and regions like south america and south east asia have been hit with a wave tube. it's a huge button for people, a nature. when temperature has regularly exceed 40 degrees celsius, the number of people exposed to extreme heat is growing rapidly. maybe half a 1000000 lives a loss to it each year. the situation is grim, i'm gonna need solutions but climate crisis fast. but how can we deal with this heat, the full tech solutions that might help?

first them a regulatory clothing, bit of a mouthful to say, versus scientists have developed the fabric keys in graphing, scroll down in hot weather and we'll see of when it's cold. so how does it work? well, a body is radiated heat in the form of electromagnetic waves. graphing can help regulate body temperature, either keeping the heat in or releasing it, whether it warms or cold can be changed by applying electricity to the fabric doesn't sound like the most practical solution when you're out and about and the weather changes. another group of research has proposed flaps that respond to a temperature, saying close when it's cold and bending to release excess heat when it's hot. the good thing about this solution, you don't need external electricity to tell the fabric that keep the heat in or release it. the 2nd solution, cooling paint, american research has developed a paint that reflects 98 percent of sunlight cooling services, up to 10 degrees celsius. below ambien temperature, meanwhile, and is really stop up is working on a multi lead coating cools when hit by sunlight. the sunlight is absorbed by the

layers and re admitted with less energy. the remaining energy causes hate to admit from the lower layer, which cools it down. it could be used to co rules, but also other things like cause. thirdly, sunglasses for windows and china research has created a transparent film that changes color, block sunlight. unlike traditionally tempted windows, this film can switch back to being transparent as single light in when it's needed . on finally, heat map, they essentially show you when it's hot away, you might find a cooler place. this works by sensors around the city mapping the heat. citizens could view such mountains by a smartphone ops upon that route accordingly. additionally, he maps could provide further information like where to find the next pulling sentence. a cooling center is an ad conditioned, quiet room. 6 people can recover from heat stress for a few hours. in addition to the cool uh that's a supply of drinking water as a particularly high risk of dehydration. when it's hot. sounds pretty nice,

but why come we'll just use conditioning? it's been i'll go to solutions to combat thing hate, but i, conditioning is simply not sustainable. ac units or energy hawks leading to higher electricity consumption and more greenhouse gas emissions, which accelerate global warming. that brings us to the real problems bottling heat . waves is only bustling the symptoms as long as we're not doing everything we can to slow down climate change, they will only get with. so how can we use ac sustainably? well 1st the energy use to power air conditioners needs to be sustainable. when so, uh, what's your name? it slot grids. good. then optimize energy distribution reducing well says i'm allowing most devices to be pilot. this works by using a i lots of data gathered from sensors around cities. let's say for example, the temperatures are rising and a so it's an area for small system within distribution will power to that sound

because it expects people to turn on that ac units. sounds good. but when we actually get that, well, even though these technologies have potential, widespread adoption is still a long way off. firstly, that price is not every city can afford to build a smart grid or houses with cooling, paint, or some kind of, but don't want to invest the money. secondly, old infrastructure needs to be updated, which takes time. result says a big workforce. and lastly, regulatory hurdles can delay the implementation of the tax. what's your take on this content knowledge you really helped tackle climate change, or is it just dropping the ocean? that us? no, that's it from me. see you next time the i keep getting these goosebumps because of the heat. i did not even know when it was possible. and the trouble is leah collapse from he took. so it was 10 in these

capital me, danny, with 10 because he's up to 50 degrees celsius. being outside can be life threatening. what can people do to cope with extreme ego, india? in 30 minutes on the w. strange and the world traveling 700 normative through the desert of mauritania is called those thousands of tons of iron and everything else that needs to get transported. and i'm the only railway line in the country. adventure is expressed in 19 minutes on the d w. the

news, i'm just trying to have a site to make the right decision to dw news and follow the

this is the, the, the news coming to live from berlin. julie massage and out of prison, and out of the u. k. the wiki leeks founder is expected to plead guilty to violating us espionage law is now on his way to a us pacific island. also coming up, germany's for mr. says the palestinian authority should play a role in post war guys on emily and a 5 bear buck is on her 8th trip to the middle east since the october 7th terrorist attacks last year. and it's really authorities step up demolitions being occupied east jerusalem in the wake of the october 2nd tax. we've had an exclusive report on how the move is ratcheting.
