they stopped working with offline data brokers to facilitate ad targeting, which is good. they closed a gaping privacy gap in their people search function that was allowing mass scraping of the public parts of profiles. i'm wondering why they didn't fix that sooner. and just yesterday, they announced they're going to be severely narrowing what data is available to app developers over a range of its api. seems like they're doing anything and everything they can in the short-term at least short of significantly changing their business model or their terms of service to tamp down concerns. so i guess the question first to harland, then to the rest of the panel, what else should facebook be doing now? and if you were in the war room at facebook at this moment, what would you be advocating for? >> so the cambridge analytica scandal raised two related but i think distinct issues. obviously we're going to be talking a lot about user privacy and the scope of sensitive user information that facebook makes available through its api to its app developers. but i think there's an equal

lot it turns out it collects data from our posts our likes or photos things we type and delete without posting the things we do while not on facebook in even when we're offline it buys data about us from others and it can infer even more our sexual orientation political beliefs relationship status drug use and other personality traits even if we didn't take the personality test that cambridge and let it be developed so you know these surveillance capitalist corporations have been collecting a lot of data on us we have mostly provided for free because we're getting a free service of course many especially in the cypherpunk community have warned that there's no such thing as free lunch if you're giving them your data for free of course you are the product also calling a crocodile's surveillance capitalists right. there are quiet in the water and waiting and waiting and waiting and then they strike so all the algorithms are employed in these corporate giannis are in place for an opportunity to make a sort of parent in a predatory early jump in rip to shreds the prey and this is one of the biggest players in the space there are thousands of other companies us by

blunt: and this includes offline data? that's linked not necessarily to facebook but some device they went through facebook on? mr. zuckerberg: i want to make sure we get this right. so i want to have my team follow up with you on that. mr. blunt: that doesn't seem that complicated to me. you understand this better than i do. but maybe you can explain to me why that's complicated. do you track devices that an individual who uses facebook has, that is connected to the device that they use for their facebook connection but not necessarily connected to facebook? mr. zuckerberg: i'm not sure the answer to that question. mr. blunt: really? mr. zuckerberg: yes. there may be some data that is knows provide the service that we do. but i don't have that sitting here today. so that's something that i would want to follow up on. mr. blunt: the f.t.c. last year flagged cross-device tracking as one of their concerns generally that people are tracking devices that the users of something like facebook don't know they're being tracked. ho

. >> what most people don't realiz tis they have wayso track your offline purchases as well, partnership with data brokers that collect information about purchases. for example if you buy a burr right owe with your credit card, these people could know about that purchase, adding to facebookessenger and start showing you ads for indigestion medicine. >> sreenivasan: i don't think that is something most people recognize, they don't have to necessarily be a facebook user. there is a vault of information collected about them by this company, in adtion to others gathering about us. >> in addition to iormation by facebook, using those tools calledeb trackers which follow your web browsing opportunities, your ip address, your potentially contact information, if you fill out a form andin like that and advertisers are able to use that to build a profile on you. >> sreenivasan: with information that's been revealed in the past couple of weeks or months how should wet be ber facebook users? >> deleting your account. i'm just kidding. there are a number of things you can do to minimize the aunt of information

data collected through an advertising tag is stored for 90 days but there's a catch. people don't usually stay offlineetches so the data is constantly collected and there is no way to opt out of that sort of collection. joining us to take a closer look is kirk wagner, senior editor for social media at recode. he wrote a great article breaking this down. all right, what's the revelation here, what's the thing that my viewers need to understand about this, if you were worried about facebook collecting all this data and said doesn't really apply to me because i don't do that stuff, that facebook collects data on, facebook has your information, too. >> yeah. even deleting an account is not going to necessarily protect you from this. if this bothers you, if this notion that facebook has data about you, facebook knows the websites you visited or knows maybe who your friends are, simply deleting your facebook account will not be enough. if you use the internet, facebook is probably watching you. i think that freaks a lot of people out. >> one of the basic things for people who use facebook, i will quote from

is whether the data the history about them but their likes their interests with their can opt in for that and that doesn't really happen with facebook right now and even tracked offline and off facebook as well and there's no opt in or opt out for that just happens also interesting to hear more concerned about whether facebook has a conservative bias many republican lawmakers bringing that up i think he so far has been performing well answering a lot of the tough questions and deflecting other ones one of the really big questions is ok now going forward is facebook going to be able to you know we're taking the freedom as they've had in the past to sort of make these decisions make these policies or could the regulators come in and dress that as well he did and i think he sees on the horizon the regulation is going to happen you know here in europe may twenty fifth there will be the g.d.p. are the general data protection regulation and that will be affecting facebook as well in fact he said. now in this hearing that he will apply those stricter privacy rules to all of facebook's users around the world so there already is regulation in the works here in the european un

under armor or pinera that our data is going to be compromised and stall and is that just the wave of the future no i don't think so i think you and i chat about this offline but i truly believe and i think the you know the regulations for the p.r. of the global protection regulation in europe this kicking off on may twenty fifth is the beginning of what we'll see you know in my vision is that we have to allow people you may anybody out there to be the owners of their data we don't have tools to do it but you know there's an opportunity there for the block and perhaps that might be the mechanism for all the things we've tried on it's to be able to get people to be the custodians of their own data or perhaps you know the next generation of a company becomes the vault and the custodian where our data is protected but we own it and we're in charge of it and you know we have a long way to go for that but i don't think that it's an impossible task to be able to get some control over critical data it may not be all data. i admired your optimism i hope you're right we want to have you back again to talk about it as we go forward the data wrangler. thank you as al

refused to directly answer whether they have fake accounts, data transfer to third parties, whether, you know, you know basically you are tracked offlinebook does track you when you go off website, he did say tens of thousands of apps are investigated for misusing data on facebook. stuart: the market thinks otherwise. the stock is up. >> he said he's open up to regulation. ashley: he has no real handle on how much information is out there, who is doing what with it and all the rest of it. i do think that he did better than we thought he would be. liz: schooled by washington, d.c. consultants. ashley: nevertheless he did hang in there. >> isn't it remarkable that expectations were so low for the ceo of tens of billions of dollar company. >> that's why the stock rallied. stuart: shah, would you buy? >> no, this is only the beginning, the stock rallied because expectations were low, he exceeded them. the senate was very weak-handed questions, i don't think there was much pressure put on zuckerberg, today might be very different. facebook is going the face it. liz: he still faces ftc investigation and fine. he didn't even notified the ftc

data is taken or used. what can it do to repair its reputation now? well, it has done a number of things very recently, like yesterday. so it has taken offlinet i think the question we have to have is whether we are happy with facebook deciding who it is that gets a ccess facebook deciding who it is that gets access to that data, and whether we are happy with facebook being the ones we trust to go and work out whether the people who have accessed it are using it in good ways. and the cambridge analytica use of data is where those kinds of issues come up. it is that facebook didn't check how that data was then passed on or used by other people. and where we get the accountability and governance around that data is the big question, i think, for all of us. it is almost like facebook's image was changed irreversibly. it was this big hug, and getting in touch with friends and family, a way of staying in touch with everyone. and now it is a business. that shift, the foundations of its very being had changed. it is a shift in people's minds, and the way they see facebook. although i have to say that the levels of trust in facebook, and how faceboo

data through cross-device tracking? >> senator, i believe we do link people's accounts between devices in order to make sure that their facebook and ingram could be synced through other devices. >> this is offline, tracking, not necessarily linked to facebook but linked to some device they went through facebook on, is that right? >> senator, i want to make sure that we get this right so i want to have my team follow up with that afterwards. >> that doesn't seem that complicated to me. now, you understand this better than i do, but maybe you can explain to me why that's complicated. do you track devices that an individual who uses facebook has that is connected to the device that they use for their facebook connection but not necessarily connected to facebook? >> i'm not -- i'm not sure of the answer to that question. >> really? >> yes. there may be some data that is necessary to provide the service that we do, but i don't -- i don't have that sitting here today so that's something that i would want to follow up on. >> now the ftc last year flagged cross-device tracking as one of their concerns generally that people are tracking devices that the users of something like facebook don't know they a
