this week, we dive into facial recognition and surveillance. casinos are betting on it. the police are driving forward with it. but this man doesn't like it. he you 90, but this man doesn't like it. he you go, look at that. £90. not bad. this face opens doors, you know. well, actually it doesn't, but it does unlock my phone. and if you do the same thing with your phone you will know facial recognition is

already pretty good. it is certainly not perfect but is not hard to imaginea not perfect but is not hard to imagine a world where your face is the key to everything. facial recognition technology is primarily being driven towards security and surveillance. even pop star taylor swift secretly deployed the technology to root out stalkers at a recent concert. in china authorities use it to name and shame citizens, even for minor offences like jaywalking — faces a broadcast on billboards. in beijing the technology is even used to stop people from stealing rolls of paper from public toilets. and it has recently been revealed that the chinese authorities are using the biometric technology to keep track of the movements of individuals from the persecuted uighur was a minority. it is a worrying example of how facial recognition can be used to track a minority group. the

big tech players are also divided. amazon has drawn criticism for using —— selling its recognition software to law enforcement agencies in the us, with al researchers from companies including google, microsoft and facebook signing open letter calling for it to stop, saying amazon's algorithms have higher error rates for darker skinned and female faces. microsoft has recently rejected a california law enforcement agency's request to install facial recognition in offices' cars and body cameras due to human rights concerns. there is work we have turned down, there ideals we have turned down in some parts of the world where governments have wa nted parts of the world where governments have wanted to license our technology, and we were not co mforta ble technology, and we were not comfortable that it would be deployed in a way that would protect people's human rights. and google has vowed not to supply facial recognition until it can come up with an appropriate policy. however

in the uk, police are pushing ahead with live facial recognition, deploying specially equipped vans to events such as london's annual notting hill carnival and major football games. i am completely co mforta ble football games. i am completely comfortable that the activity we are doing in the trials is lawful and appropriate. but this has become a highly controversial issue, with civil liberties groups claiming that the technology is inaccurate, intrusive and infringes on an individual‘s right to privacy. the last year, jeff white has been following the uk police's deployment of facial recognition. the frontline in facial recognition. police cameras in e. london st, everyone gets scanned. if you refuse, here is what can happen. don't take my photo, don't... this man did not wa nt to

photo, don't... this man did not want to be caught by the police cameras so want to be caught by the police cameras so he covered his face. police stopped him, they photographed him anyway, an argument followed. what happens if you walk down the street... what is your suspicion? the fact he has walked past a clearly marked...” suspicion? the fact he has walked past a clearly marked... i would do the same. they are just grounds. .. the police said this was disorderly behaviour so they gave him a fine. they said they have facial recognition, so i walked past like that, it is a cold day, i have done that, it is a cold day, i have done that, the police officer has asked me to come to him. i have got my backup, i said to him, (bleep) off, basically. i don't want my faith in anything. if i want to cover my face, i will cover my face. no—one is going to tell me not to cover my face. i have a £90 fine, thanks lads, £90, well done. he was caught up lads, £90, well done. he was caught up in the last of ten trials carried out by the metropolitan police. the

met have had success, there were three arrests from facial recognition on this day alone, but the trials have proved controversial. opponents say they are taking place in a legal vacuum. there is nothing in uk law that has the lord's facial recognition. there is no legal basis for police to be using facial recognition. there are no legal limitations on how they can use it, no policies, no regulation. this is a free for all. we don't know who was on the watch lists, we didn't know how long the images were going to be stored for, and the police are kind of making up rules as they go along. my ultimate fear is that we have live facial recognition capabilities on our gargantuan cctv network which is about 6 million cameras in the uk. if that happens, the nature of life in this country will change. it would mean that everywhere we go we could be identified, tracked, that we would be leaving a location data trail, that your face could be

searched and a detailed record of your movements again. police argue that in a time when every smartphone camera has facial recognition, why should they be left behind?|j should they be left behind?” believe, as does the commissioner and the management board of the matter, believe not trialling such technology would be neglectful. we ought to explore all technology to see how it can keep people safer, how it can make policing more effect. however we are completely aware of some of the concerns that are raised, and what we're doing with these trials is trying to understand those better, so we can actually protect human rights but also keep people safe at the same time. we are reviewing all capabilities in terms of live facial recognition. absolutely the technology is there for body worn or smaller devices to be fitted with facial recognition technology, as with cctv. so absolutely we will look at that, but again the right safeguards and reviews have to be put around that. it is notjust

cameras on vans. last summer outside one of london's biggest shopping malls, release cctv scanned thousands of shoppers. it was aimed, they say, at spotting known criminals. people who are unlawfully at large, may well be reoffending, and we need a tactic, another tactic, which is why we are employing this technology now, to apprehend these individuals and bring them tojustice. apprehend these individuals and bring them to justice. that is what the people want and that is what we are responding to. i want to be absolutely clear. the technology is very accurate and reliable. the human intervention side is to safeguard —— is the safeguard we have got in place. despite the warning signs, many passers—by do not know what was happening. when they found out the reaction was mixed. some thought it was an improvement on current policing methods. it is better than stop—and—search. it is better than stop—and—search. it is better than stop—and—search. at least that would be disseminating. it is a bit creepy, i have to say. i wouldn't

like to feel like i am being wanted all day long. it is notjust in london that the tech is being tested. south wales police have carried out more than a dozen trials, including at the champions league final, using similar equipment to the mat. it is quite cosy, isn't it. let's have a look. so we have two cosy, isn't it. let's have a look. so we have two cameras cosy, isn't it. let's have a look. so we have two cameras on cosy, isn't it. let's have a look. so we have two cameras on the roof of the vehicle, one at the front and one at the back. both have 360 ability, so we can control them from and the vehicle. all around the vehicle. when tested on a member of police staff the system quickly spotted her face and police staff the system quickly spotted herface and maxed it almost insta ntly to spotted herface and maxed it almost instantly to a file photo, even though the two were quite different. if you are heading to our headquarters, it has come up with julia gardner, it shows her name and almost instantly. once checked that alert can be related to an officer in the street who can approach the suspect and verify the match. the

system is incredibly sensitive. the eyes a re really system is incredibly sensitive. the eyes are really important in terms of facial recognition technology. 0ften of facial recognition technology. often the eyes are visible with face coverings, so the technology does work with motorcycle helmets as well. using facial recognition is not new for the police. what has changed is that systems like this one work in real—time and across massive numbers. the system acts as a big filter, it enables the officers to find that needle in a haystack. if you have hundreds of thousands of people walking past the camera it would be difficult with the human eye to stop one of the people you are looking for. so it gives the officers an indication, so it could be that individual. the system works by matching the camera footage to a database of file photos, and that is part of the controversy. so—called intelligence databases include controversy. so—called intelligence data bases include people controversy. so—called intelligence databases include people who have never been convicted, as does the police national database, never been convicted, as does the police national data base, which includes more than 10 million

photos. that database then could include people who were found not guilty, innocent people. at the moment, they can have their image removed. 0nly moment, they can have their image removed. only if they apply to, but measures are afoot to automate the process. south wales police and the met have finished their trials now but in the meantime both forces are facing legal action from privacy campaigners over there use of facial recognition surveillance. one of my concerns, recognition surveillance. one of my concerns, i don't know how you feel about this... baroness jenny jones have strongly backed the legal challenge and has personal experience of the issue. the police national database has all sorts of people like me and you do not have to have committed a crime, not even be arrested to be on that database. that suggests to me that it is an extremely flawed way of trying to keep track of people, and once you are in it and once that information is on there, you have to request that it should come off, which is what i did finally. but you have to

know that it is on there. if you don't know it's on that you can't get it removed because you can't make the request. and that means that it would be lots of false positives on the system. so for me this is a very foolish move, and what is even worse is that it is so inaccurate that on previous trials it has been 2% accurate, that means 98% inaccurate. the policejudgement at times is very poor, and i can sort of see why they think this might bea sort of see why they think this might be a good thing to do but actually it is disastrous, and the sooner actually it is disastrous, and the sooner they listen to people who are saying "you've got to, if not stop completely, at least road back a bit, have a pause and actually make sure you are using it in the right way." that sure you are using it in the right way. " that was sure you are using it in the right way." that was baroness sure you are using it in the right way. " that was baroness jones knitting jeff's report, and facial recognition is really controversial get the police are still going ahead with it. their argument is that this isn't anything new. police officers have always had the usual suspects

in the back of their mind, looking out for them on the street. what is different here is the speed and scale. it is not a case of a police officer looking out for someone, it is cameras scanning hundreds and thousands of faces and comparing them to a database. and that is what has campaigners worried. he mentioned the usual suspects which implies police are only using previous suspects' images. whether they get their data from? a lot of police forces are using the police national database. this police forces are using the police national data base. this is police forces are using the police national database. this is a stash of millions of images police have accumulated over the years. there are accumulated over the years. there a re controversies accumulated over the years. there are controversies over how they have accumulated, whether that data base should exist, and who is on it, these are some people who have been arrested by clean of any offence. another problem we hear about with artificial intelligence is the problem of bias in the training data, where a lot of ai is trained on white men, and so it is not as good at recognising the more diverse range of people that exist in the world. 0ther police aware of any bias is in the training data and what i doing about it? as part of

investigation we have found that police on several occasions had golden opportunities to take how well the software and systems deal with a black and minority ethnic faces, and on education they have to investigate that. —— each occasion. the problem there is that there are already problems with power police deal with these communities in terms of stop—and—search, if this rolls into facial recognition there is another problem viewing —— brewing for police with this technology. welcome to the week in tech. it was the week that hackers stole $41 million worth of bitcoin from major crypto exchange finance. urban —— uber drivers went on strike. an a new smartphone revealed. hope that

it will increase the popularity of that brand. robot to deliver parts ina bit that brand. robot to deliver parts in a bit too free up its human employees to do more complex tasks. detection and sensors to navigate the plant layout and modified its route if encountering obstacles. famous for smashing guitars but this would have spoiled their fun. famous for smashing guitars but this would have spoiled theirfun. an almost indestructible 3d printed lightweight guitar has been developed by a swedish engineering company. and finally, the annual met gala energy provided quite an array of outfits, including this, address with 37 3d printed petals, created and worn byjordan dunn, it took over a thousand hours to create so

it is not beating the race against the sewing machine any time soon. now, it is notjust the police who we re now, it is notjust the police who were deploying facial recognition technology. increasingly private companies are starting to offer and buy services also but the data collected and the places where the technology is being deployed is starting to raise eyebrows. at this giant manchester mall in 2018 an estimated 15 million people were scanned over 15 months. it led to just one positive identification. the scheme was halted after the uk cctv commissioner raised multiple legal concerns. 0ther cctv commissioner raised multiple legal concerns. other businesses though are pushing ahead. the british supermarket change, southern

co—op have aspirations to build one of the uk's largest database of facial images of alleged criminals. the company started in a london bar. gordon's claims to be london's old est gordon's claims to be london's oldest wine bar but inside here is some cutting—edge facial recognition technology and the company supplying it has some big ideas for where it is going next. everybody who comes into the bar comes through this entrance. it comes through this entrance. it comes in, looks around the bar. he clicks the monitor. it has seen his face. you are a private company and this is a private business. shouldn't the police be doing this?

we have the opportunity to work with the police. we are in the process of working towards an information sheet agreement. hopefully it will contribute to the police giving us their list of low—level criminals. businesses who user system load up people they suspect of wrongdoing. it stores the images and shows them among its customers. the software then automatically spots those people when they walking but that includes potentially innocent people. they have not been convicted? not necessarily but we have to have evidence for capturing and uploading that information. the database of and uploading that information. the data base of people, and uploading that information. the database of people, you are not making that public. i cannot see if iamon making that public. i cannot see if i am on there. it is a private database but essentially you or any

member of the public can be subject to face what we can tell you if you are on the system. if i want to appeal? i think you are only likely to appeal if you have a cause for concern. so far, in all our trials, there is evidence of cameras in this case, we have not had one request to date. they say images are deleted automatically after two years and says it is talking to the police with a view to sharing databases of suspects and it is notjust pubs and shops. facial recognition is being used to protect some very high—stakes used to protect some very high—sta kes businesses. used to protect some very high—stakes businesses. you would expect a busy london casino to have a lot of cctv ‘s but the one on top of this elevator is a bit different.

it has facial recognition software installed. it will match the database to see if i am someone who should get a warm welcome or chucked out. the casino scan everyone who comes in. we have a database of about 3000 customers and these are customers generated from images both internally from customers we have identified as having a problem with gambling and also customers who have declared they may have a problem in relation to gambling and we have also taken a number of those images from another data base and also taken a number of those images from another database and this is a database for people who wish to voluntarily and roll and exclude themselves from casinos across the uk. the future for facial recognition to ology is mobile and specifically thinks like this. this isa

specifically thinks like this. this is a body worn camera and sits on a policeman like this, the ideal height of facial recognition technology to work. one british firm pushing ahead with this kind of mobile facial recognition is digital barriers. all they need is a few photographs from the internet to make the technology work. richard has got the same software on the phone. the phone has never seen me before but we have given him pictures from the internet of me. we will see if the phone can recognise me from those pictures. it can also track when and where a match is made, meaning that with several cameras, people can be tracked as they move around. this can turn the trail into a map stop for the company behind them, these devices area company behind them, these devices are a step change. this second—generation that we will start seeing will have the ability to

strea m seeing will have the ability to stream video in real time back to control rooms and also to run live facial recognition. it is a new generation of digital policing. with the advent of artificial intelligence, systems will be able to compare their footage against databases of tens of thousands of images. that gets you into dangerous territory. if you take the example ofa territory. if you take the example of a city like london, which has a counterterrorism challenge, clearly the prioritisation on that watchlist is different to somebody who may have an outstanding traffic warrant. my have an outstanding traffic warrant. my nervousness is when it extends into more commercial and less regulated use of the technology. the idea that a commercial organisation can build a database and put it out

into the world and start to look for people with no real controls of how the watchlist is being built is very serious and does carry implications, particularly as a technology becomes cheaper and more available for people to buy. earlier we said microsoft refused to put facial recognition into body cams and yet you are saying other companies are doing it. body cams have accused advantage. —— have a huge advantage. they cover wide angles. this technology does not have to be in a body camera but also a mobile phone. this is the direction of travel. body camera but also a mobile phone. this is the direction of travelm is going mobile. private companies using public data, please tell me that someone somewhere is regulating

this. the tragic news is, not at the moment. there is no uk law for facial recognition. it does not even p0p up facial recognition. it does not even pop up in any legislation. there is a bit about surveillance, a bit about biometrics and a bit about personal data and all these people are looking into it and there probably will be legislation but the danger is that by the time it comes out, technology would have sped up. it would be too late. a lot of people think that it is just about recognising the face but behind it, the whole point of getting this pictures is it so i can find out information about you — criminal record, shopping habits, driving record, shopping habits, driving record so it is the data behind it thatis record so it is the data behind it that is the real issue. thank you for your time and thank you for those brilliant reports and if you have any views on the subject — get

in touch with us. that is it for this week. thank you very much for watching and we will see you soon. hello there. gradually it's an improving picture this week. we've got high pressure moving in which will kill the showers. we'll see more sunshine around and it will turn a little bit warmer for most of us as well. but there's no heatwave on the horizon. it'll feel a lot better than we've experienced over the past week or so. low pressure, which brought wet weather to southern parts of the uk during friday night, will clear away. we could start off with early showers, particularly across the south—east. these will tend to fizzle out. many places starting off this morning on a chilly note, but bright and with plenty of sunshine. then we'll get the

showers going again. in the afternoon they're likely to develop in the northern isles, one or two across scotland, otherwise plenty of sunshine here. quite a chilly breeze across northern coasts. most of the showers will be across central and eastern england. the odd heavy one, maybe the odd rumble of thunder too. the best of the temperatures here in that north—westerly wind. i think we'll see highs around 15—17 degrees. the showers fizzle out tonight, but it will turn chilly. largely clear, a bit of mist and fog. likely a touch of frost across parts of scotland, but less cold in the south and south—east. sunday, high pressure right on top of us, keeping all these weather systems far away from us. so it looks like it's going to be a fine and largely dry day. it will start off chilly, mind you, especially in the north, with light winds and plenty of sunshine. those temperatures will begin to rise in the afternoon. could see some fair weather cloud

developing here and there, and just the outside chance of an isolated shower. but most places will stay dry. temperatures reaching into the upper teens. next week we still have high pressure with us but what it will be doing, certainly as the week wears on, is tapping into cooler air of the north sea, whereas further west it will be tapping into warmer air from the bay of biscay. so it looks like next week, though it will be largely dry with sunny spells because of high pressure, it's more likely to be cooler in the east and a little bit breezy as well, especially along north sea coasts. this is the picture on monday. largely dry. a fairly cool feeling. through the afternoon temperatures will be rising nicely. we should see highs of around 18, maybe 19 celsius in the warmer spots across western areas. generally speaking, the further south and east you are over the next few days, it will be cooler, especially on the coast. inland it is always a few degrees warmer, with temperatures further west doing much better. in fact, the north—west of scotland could fare best.

this is bbc news. i'm reged ahmad. our top stories: the us and china promise to carry on talking, but president trump begins the process of raising tariffs on remaining chinese imports, worth about $300 billion. at least 65 migrants drown trying to reach europe from libya, when their boat capsized off the coast of tunisia. killed by rabies, the norwegian holiday maker bitten by a puppy in the phillippines, the first fatality in norway from the disease in 200 years. and what happened when vladimir putin tried to wow the crowds at the ice hockey?
