period to ensure a smooth separation process between britain and the rest of the european union. she's promised to meet the uk's budget commitment. prominent figures elsewhere in the eu have praised her tone but asked for more detail. us officials say intense rain and flash floods have caused a dam to fail in puerto rico, causing an extremely dangerous situation. tens of thousands of people are being evacuated. hurricane maria brought torrential rain, swelling rivers to record levels, and knocking out power to the whole island. the ride—hailing app uber has lost its license to operate in the british capital. london's transport authorities questioned the firm's approach to driver background checks and the reporting criminal offences. the online minicab service has confirmed that it will appeal against the decision. now on bbc news, it's time for click. this week, how safe is your face?
1:31 am
pinpointing pollutants and... i'm not sure you're pointing that hairspray to —— the right way, love. the right way, facial recognition. technology that can identify someone from their face is fast becoming a thing. this biometric id has been used together with passports at immigration control in airports. in dubai, they wa nt to control in airports. in dubai, they want to do this without the gates, allowing passengers to walk more easily through the airport. it is
1:32 am
also finding its way into apps as an alternative to passwords. face recognition could be coming to shops. in china, one store recently premiered a smile to pay system at kfc. unlike our passports and passwords, our faces are on public display pretty much all the time. that makes it possible for the authorities or anyone else to automatically identify us in any public space, something you may not be surprised to hear they are quite interested in doing. dan simmons has been looking at the preparations made by several governments. to start, you've been to germany? yes, it seems we could be moving towards a biometric cctv is sort of state. one of the places where it is first happening, which may surprise you,
1:33 am
is in berlin. catching a train in the german capital means you might be caught on cctv, perhaps while stamping your ticket. the system automatically track your movements, which at the least requires human intervention. but in the south of the city, your face will be scanned and analysed by computers. the testing of facial recognition began here last month. the authorities are not looking for criminals just yet. they aren't really looking for me, either. around 200 volunteers have had theirfaces either. around 200 volunteers have had their faces and and been given a location tracker so the authorities know when they pass through here and they can see how often the cameras can pick them up, just by looking at theirfaces. if can pick them up, just by looking at their faces. if the system's accurate enough, then it will be used much more widely, which for
1:34 am
many, would be a breach of privacy. being constantly monitored with no easy opt out. the germans have a history of being watched. this old listening station in berlin was how the west can tabs on east germany. on the ground below, first the nazis and then the stasi is kept files on the population. since the fall of the population. since the fall of the berlin wall in 1989 and the decommissioning of checkpoints, berliners have been fiercely protective of their privacy. what has changed is that a new threat has replaced the old. police controlled the crowds in the aftermath of a terrorist attack. a truck mowed down shoppers in berlin, 12 were killed and more than 50 injured. at this time, cctv is still not widely used
1:35 am
in public. three months later, the government passed new laws to extend their use in the face recognition pilot was given the go—ahead. despite the trial offering a route that passengers can take to avoid the cameras, the country's top lawyers have expressed concern about germany moving towards a surveillance state. no one is saying facial recognition couldn't help catch criminals, but the public does not feel they have been asked. as jeremy goes to the polls, one member of the coalition has in power told me he wasn't consulted about the trial and the technology has not been publicly debated in parliament. it does not bring more security. it is just collecting data, it does not bring more security. it isjust collecting data, more it does not bring more security. it is just collecting data, more and more. you don't know where this data may be used. they tried to give it to the people, but it doesn't solve
1:36 am
the problems. proponents of the scheme point to the dip in crime following the installation of cctv in 2011. we asked the german interior ministry and the police authority for an interview and to ta ke authority for an interview and to take a look at the technology, but both declined. we ask some travellers. i don't trust the system. i don't trust this new development. like everybody should be tracked and stand. they showed on television that if you have a cap on or sunglasses, it cannot track you —— scanned. but if it catches one, we are very happy. it really shows that it will help. then i will be ok with it. in the hope that there is i'io with it. in the hope that there is no misuse and nojust collecting
1:37 am
tracking data. if those worries are widespread, it is not looking good. questions hang over whether the german police fabricated records on the man behind december‘s terror attack to make them look good. earlier this month, a report said 21 eu member states, including germany, are still unlawfully collecting and retaining personal data. who's watching the watchers? that may be the key question if the technology proves its worth. we are tracked by oui’ proves its worth. we are tracked by our phones every day anyway. what is the big concern around facial recognition? with phones, we can possibly turn them off or opt to carry a more basic model. we do have some choice. it tends to be companies that collect data. when the police or the state require that
1:38 am
information, it is a case by case basis. the concern here is that if we introduce facial recognition, there would be a very broad data base, a surgical data base to find out where each person was and with whom whenever they were in public. to be fair, it is dust trail. this been released yet? no, it is a trial, absolutely. just on 250 volu nteers trial, absolutely. just on 250 volunteers and in public where they are captured on camera. there is another capital city where this technology is already being used by the police to look for real suspects? yes, here in london, where the most recent trials took place last month. carnivaltime in notting hill. tens of thousands gathered and we re hill. tens of thousands gathered and were monitored above, and by officers on the ground. there facial recognition cameras, and unlike in
1:39 am
berlin, the london trial is not visible to the public. the officers are using it to spot real suspects. the metropolitan police declined to show us the technology or to interview, so we spoke to an expert who was invited to witness what happened. in the ten minutes that i viewed facial recognition in action, i saw two miss identifications. both of them wrongly identified an innocent woman walking past as a wa nted innocent woman walking past as a wanted man from the police data base. those of false positives, other police concerned about that? they won't worried about that, but they were running it for four days. they told us that they had made many false positives. she says officers told her they had made one correct match in the four days of use. the
1:40 am
people i met viewed this as a success. people i met viewed this as a success. as long as they can prove that the software works, it can make a positive match, even if it is making a0 incorrect matches, then it works. that's not the scientific approach. there is no balance or proportionality, let alone the civil liberties issues. that is not a success liberties issues. that is not a success to a new. some will say that the technology needs to be tested in real—world circumstances and this is what the police are doing in this situation. they have to test it and it could be useful in future? we all have something to worry about when the police are using intrusive biometric surveillance powers, and that they are doing largely in secret. these kinds of surveillance tools present some really broad
1:41 am
concerns and to simply say, i have nothing to hide, therefore i have nothing to hide, therefore i have nothing to hide, therefore i have nothing to fear, is to unconditionally submit to powers of government that are unchecked. that is to say, whichever flavour of government comes in, would we be happy with biometric surveillance? i don't think we would. london's metropolitan police told us: they declined to comment on the effectiveness of the technology. that is slightly concerning, isn't it, especially if the software really is that inaccurate? we haven't had any kind of public debate about whether this technology should be used ? debate about whether this technology should be used? no, not really. the
1:42 am
police say there will be a public consultation. we asked them how long we would wait for that and they said it would happen in due course. we checked parliamentary records and although facial recognition has come up although facial recognition has come upfor although facial recognition has come up for debate within other bits of legislation around anti— terror laws, there has never been any specific debate around the use of facial recognition in public in the uk. the technology continues to advance and researchers are looking at even more complex technologies? in last month, said they are developing a system which could potentially identify people with scarves over their faces or wearing hats, and stanford university in the us say they have developed algorithms that can look at the results of what comes through the camera results of what comes through the camera and determine somebody‘s sexual orientation. you are looking
1:43 am
at something potentially in the future when this technology starts to ta ke future when this technology starts to take off where you could walk past the camera and automatically be added to a database you would not necessarily know about, and therefore, you could complain and get something done, but you wouldn't even know that it had happened. lot to talk about in the future, thank you. from filming your face to feeding it. this is london's borough markets. a paradise, stuffed to the gills with gourmet grub. this week, designers from the royal college of art alongside inventors have descended on this bustling street market to show off a host of gastronomic gadgets. first up, bottle openers that are supposed to make beer tastes better. according to one student, the flavour will be
1:44 am
better as a result of the satisfying sound. instead of mixing vast quantities of a recipe before unveiling to the public, this professor has been experimenting with crowd sourcing ingredients using a game that mimics the stock market. having a large number of consumers and playing the game, knowing what their preferences are, we are creating the formula. bottoms up. this student has created cutlery with handles that can be heated, which claimed to slow down children's eating which claimed to slow down child ren's eating habits. which claimed to slow down children's eating habits. slower eating has been shown to make us feel for more quickly. it is hoped that these knives and forks will do just that, encouraging healthier eating habits in children. finally, overin eating habits in children. finally, over in the kitchen, students hope
1:45 am
to capture family recipes that have been passed down from generation to generation by analysing video of visitors preparing food and collecting data attached to cooking utensils. recipes will be generated to record the way individuals prepare food. we believe people are better able to articulate their preferences around food using their bodies. we are putting sensors in kitchen tools to capture those ideas and developing a repository of those old families of recipes may never be lost. hello and welcome to the week in tech. apple released a new version of their operating system. google announced an 800m pound deal with htc and transport
1:46 am
for london said they will not renew the licence for uber. uber said it will appeal the decision. it was also the week by minister theresa may called for technology companies to work further and faster in removing extremist content from the web, she also called for search engines to take down terrorist materials within two hours of publication. history was made this week is an electric vehicle broke a world record at travelling more than 1000 miles on a single charge. the bus travelled 1102 miles on the testing ground in indiana. the company has not revealed how fast it was going, saying it travelled slow and steady. we told you about the tragic demise of our good friend,
1:47 am
steve, well, a new breed has been spawned. it has been specifically designed to fight crime in large areas with difficult to rain. will it suffer the same ill fate as steve ? o nly it suffer the same ill fate as steve? only time will tell. that is the smell of a killer! as the words of london's mayor who said that london's air—pollution is way beyond a cce pta ble london's air—pollution is way beyond acceptable levels. you cannot really smell much but the health problems causeway cars —— caused by cars. in a few minutes, we look at pollution in unexpected places but first we are off to san francisco with
1:48 am
another place with lots of diesel pollution and a lot of people with breathing problems. we look at people trying to pinpoint pollution is. we cannot detect them but this car can. inside is a minilab from a company that monitors air quality. we mounted this system onto the street view that has both meteorological and inlets equipment. one yet, they crisscrossed with california, roughly 12 square kilometres, home to a bustling port and families. 37,000 kilometres and researchers had this detailed pollution map. stephen, of the
1:49 am
environmental defence fund explains how. we need fast response in cement that we record data. we map it in a way that is character rising that local spot. each dot represents around 30 metres. the darker the dot, the dirtier the air. red dots cluster around hotspots like busy intersections. researchers hope this data will help regulations from being introduced. all these equipment crammed into this car, it is high precision stuff and too pricey to put on a fleet of vehicles so pricey to put on a fleet of vehicles so they have developed a sense — 100 times cheaper and about the size of
1:50 am
a couple of shoe boxes. imagine adding air—pollution is a layer in your applications. the number of times and we need to sample a region to get something which is best for that area and understanding the baseline. by now, they have a real—time tracking tool and that is more thanjust real—time tracking tool and that is more than just a breath of fresh air. it is easy to think of air is an outdoor issue but maybe it is time we start to think about the air that we are breathing inside our homes. air—pollution comes in many forms. in our homes that includes outdoor polluted air coming in through open windows as well as being caused by cooking, lighting candles, or the use of everyday
1:51 am
products. so the test a couple of the latest indoor air quality trackers, i have enlisted the help of professor roy anderson who is his own kit at hand. first off, time to ta ke own kit at hand. first off, time to take a base reading. firstly we have this. it gives us three different pollutant measurements. particular matter. except it is not telling us what size. we are getting a little less tha n what size. we are getting a little less than that on our device. but it looks like a very plausible reading. and at this. in terms of air quality, it is measuring carbon dioxide. slightly change because from a health perspective it is not one we are very concerned with. although the professor did add this
1:52 am
reading was two low to be possible. for our first experiment, let's reading was two low to be possible. for ourfirst experiment, let's burn some toast. things are really peaking. those are very high concentrations. beijing type air quality, not london. it has not reacted at all to this smoking episode but maybe burning toast does not generate much carbon dioxide, u nless not generate much carbon dioxide, unless you set fire to it. it obviously knew there was a problem. what do you make of the readings? you look at the volatile organic compound, it has gone up tenfold and thatis compound, it has gone up tenfold and that is very possible. i surprised that is very possible. i surprised that the particular the matter has
1:53 am
not responded. maybe it is a very slow. on to experiment to and luckily the professor was happy to play a long. the hairspray alarmed the particular matter. the main component of the hairspray is up to a thousand a00 so that has gone up a lot. what is very strange is the carbon dioxide has gone up to 30,000. which is a level that would worry me to be breathing. it is a huge level. it is a little hard to breathe in here at the moment. it is all very well to know the quality of
1:54 am
the air but you may want to do something about it. a device like this aims to purify the air by tracking it, so it knows what the quality is, and if the quality is poor it will do more purifying and if the air quality is ok, then it can pause. the dyson you're calling does come with a hefty pricetag and this model is the size of not so small child. it filters that the air and disperses clean—air back into the room. clearly we had a spike in the room. clearly we had a spike in the pollution level that it has not gone as high as in the earlier experiment. i am gone as high as in the earlier experiment. iam impressed gone as high as in the earlier experiment. i am impressed that it is coming down more quickly than i would have thought. my test seem to indicate the rather odd result that fixing the problem may prove simpler than actually monitoring it. that is
1:55 am
for this week. don't forget, we live on facebook and twitter. check us out throughout this week and every week. thank you for watching and we will see you soon. the autumn equinox may be behind us now but the weather is feeling reasonably summery for some of us over the weekend. this was the scene on friday afternoon. as we head through the course of the weekend, many of us will have largely dry conditions, particularly on saturday. by sunday there will be rain heading into the west of the uk and temperatures will be on the rise as well. as low pressure sets out towards the north—west with tight isobars here but at the moment high—pressure is dominating the south—east. as we start saturday morning, there will be a little cloud and drizzly rain across southern parts
1:56 am
of the country. some low cloud, mist and murk first thing. it should brighten up during the day. if we have a look at saturday morning, nine o'clock, after a chilly start in scotland and northern ireland it should be dry and reasonably bright with a little sunshine into northern england and a little more cloud and drizzle and hill fog across the southern half of england and south wales. waking up to a grey morning here but certainly mild, fair weather as it brightens up during the day. a fresh start for northern parts of the country, moving towards the south. through the course of the morning this cloud and drizzly spots of rain willjust ease towards the east. for many of us it will brighten, particularly along the south later in the day. a little more cloud pushing into northern england and scotland and the breeze picking up across northern ireland. all in all, a decent day with temperatures for most of us around 17 to 19 degrees. it should feel quite pleasant. into saturday evening, most places end the day on a dry note. on saturday night and into sunday
1:57 am
you will notice a band of rain working towards the west. that is a weather front and the breeze peaks as well. across much of england and wales you should begin the day on a dry note once again. it will be mild, certainly. through the day on sunday, the weather front tries to move in from the west, bumps into high pressure in the east so it will tend to fizzle out somewhat during the course of the morning. there will be some rain for northern ireland, scotland perhaps the western fringes of wales in england. later in the day, a chance of a few heavy bursts working in but further east across much of england and wales remains dry and bright and pretty warm. 22, 20 three degrees in the sunshine. just a little cooler in the north—west. we still have a weather front lingering around on monday that will fizzle out during the day. the east should stay warm and dry with temperatures 19 or 20 degrees. welcome to bbc news, broadcasting to viewers in north america and around the globe. i'm duncan golestani.
