i already know hey, it's adeena. 30 years old. listen cologne, originally from cedar trained and communication 1st and now studies business administration. she told me all of the of her own volition. but i know more than that. i even know her biggest secret. how? well, i don't want to give away too much, but i will tell you this. i collect data. i'm facebook's database. i know what edina likes, music by kluso for example, and she's a fan of by a live of course and of her gym. i know which posts she likes and what she shares with her friends, her comments, the people she sends messages to and what she writes, i can watch her outside of facebook too because the dina has enabled access to location data. so i always know where she is and can see where she regularly spends

time. 3 times a week, she uses this cafes, why fi? most likely she works. there may be to pay for her studies or for something else. her location data also allows me to see which other facebook users are close by and whom she off meets including at the cafe. this is probably a colleague. this guy stays over almost every night. i'd say he's her boyfriend. but every once in a while, another profile is at hers and at night too, oh, i know this guy. but this isn't her only secret. as i learned with the help of her activities on other apps. she uses this one to shop.

want to use or email or facebook to sign in facebook as convenient, right? just one click and you're in and usefully, it means more data for me. i didn't recently stopped buying wine. she is currently opting for smoothies frozen pizza and pickles. and when i show her this photo of her friends baby on facebook, she hesitates just a little longer than usual. interesting. know the data points to one thing, but her boyfriend doesn't know yet. and neither does her colleague how can we leave as little dot online as possible, is deleting cookies and browse history regularly enough to surf anonymously to people allowed us to use their profiles to tasteless. oh,

jessica vega is often online but she wants to remain as anonymous as possible. oh, she's installed an ad blocker and she regularly deletes have browser history. oh, which was a for the fists was i tried to be careful and mindful of which information i share from. i really tried to protect my personal data as much as i can when i'm online. i'm so mama's will dis, prevent companies from collecting her data. will, can they profile jessica? in spite of it, mark, italy is less worried about his data. he has 20 apps installed on his phone, 11 of which he uses regularly included apps that belong to tech giant meta and google. which it can it in 40. does i see the advantage more of google and facebook using my god to make recommendations and sure me ends

giving oh, we joined both jessica, unmarked for their daily digital routine to see which data is connected and how it's used for personalized advertising. martin clayman is professor for marketing at the codes room institute of technology in germany. together with a colleague, he's going to take a look at the digital traces. jessica and mark leave online and see which can be used for individualized ads. most options are the thing that you have on spectrum that you'd really have to invest a lot of time and energy to browse the internet anonymously. i think the average consumer doesn't quite well to stop the data from being collected or not to empty. jessica regularly check this news website. the page saves the so called cookies. small data packages are unique identifiers on her computer. we ask the marketing experts to take

a closer look at the new site. these cookies contain data on jessica's preferred language and other personal settings. so far so good, but they also find so called 3rd party cookies symbolized by these triangles. these cookies enable companies to follow people who've visited the new site as they continue browsing the web because they are accessed by other sites as well. if jessica visits one of these pages, they recognize her and collect important data on her online behavior. the jessica regularly deletes her browser data, including cookies. is it nonetheless possible to track and identify her. 2 2 like with old uses, her browser automatically sends data like screen resolution fund system software and time zone to a given website operator. 2 they use this information to optimize their site. she visits a my unique dot org to check whether this means she is identifiable on line. so the result is, yes, no other user transmit the exact same data as she does. website operators can

therefore identify her track her and place ads even without 3rd party cookies back to ma keighley, who wants to buy a new laptop online. he's been looking at options on different websites and has found one he likes, but he's dylan. sure. so for now, he adds the laptop to his cart and had to university online office and computer dealers keep popping up as he serves the web there, even on his phone advertises no, both devices are his because marcus signed into his google account on his laptop on smartphone. websites that have google cookies show him personalized ads. google also places ads online. jessica notices this when she google's common such

times and as shown, matching ads. this service is called google ads. the company auctions off ads that are displayed whenever uses and to sets in terms into his search engine. the more frequently the time is looked up, the more the advertiser has to pay for their i to be shown. it's a form of targeted advertising for which user profiles aren't even needed. facebook's approach is different. it's business model is to enable advertisers to show their routes to exactly the right uses. to examine how it works, our marketing experts place an ad on facebook which they want to appear in march ag feed. they select the criteria accordingly. oliver began since the lease molded. we consider the location to karlsruhe and can narrow down the exiting oscar. and we can add male for gender of middle jenkins, dad to say, how old is with the english to go to the swines once is sold to us. i think we should be good with the age bracket. 18 to 22. we're an eagles and we know that he

likes football and supports manchester united as interest so we can add that to interest does from align stern. also the investment. we also know that he was born in guatemala to mala comp, which we can add as well can the on the on leave. they are ready to publish arrived . if the moment of truth will the ad appear amongst facebook feed. it does next to photos imposed by his friends. there's the ad. but mark eagerly. it's not very concerned. let's say all night long business, sean, are you in ways a bit scared of the companies like facebook, google and sophie le you? but i think there is so many uses that are more interesting for advertising purposes for an online attack than i am that it's relatively uninterested of relative only $200.00. jessica vapor has

a different opinion. she uses the services, but she doesn't like being constantly tracked versus of unifying. there's definitely a strange feeling to know that there are databases which contain your shopping profile and that these profiles are being sold on to others without you ever knowing what they're being used for and what happens to your data. cashless payments are convenient and quick, but i'll the disadvantages to a world without cash bins can bargain back if we no longer had cash, we wouldn't be able to pay anonymously any more thought we'd always leave data traces that would be analyzed and used to manipulate as i'm in the money put these days. people increasingly pay even small sums with card all my ball payment. and e commerce is booming. with each electronic payment we make meta data is collected about us that could be analyzed by algorithms such as our location or how long we

take to purchase an item online. oh, how often we make typos. tech companies use our behavior to create predictive profiles. payment data is especially telling farms doc, mom and daddy payment daughter. this aspect of confirmations are off so you can create a profile about someone and say this person tends to do this. so let us get on with payment data, you can see what they actually do, what they're willing to spend money on their comped. it's like a promise where profiles are confirmed or questions. it's sort of like putting them to the test people. if i've got payment data, i know what that person has really liked webpage ticked. ah, companies use this to target tests with ads in the future. we might even be given individualized online prices depending on how much we were willing to pay in the past. ah,

see all the noise and image eigenschaften so they observe our characteristics and to even the sign psychological traits to us that we ourselves may be unaware of feeling. this means that these profiles for the old, this is but the provider's claim are smarter than we are. and also the, the profile knows you miss. and you truly want some needs more than we can see some think you might want to put on to. and that's with the manipulation starts. if not before i'm finished, i don't know that i'm susceptible to certain context that i might not act wisely in certain situations. and i don't know that there are products that irresistible to me looked at it as a school due to kept engine swedish d. and come more dates, i mean, more accurate profiles. so how predictable do we want to be? ah, ah, ah,

palm trees see an empty beeches spring in my orca. before the holiday crowds takeover luca stig explores the german torres, this favorite islet. ah, why is my orca so popular? that's what i want to find out to again next on d, w, it's a powerful form of protection for the body and soul gentle touch. it's crucial for human survival for our health and psychological development. but what happens when people can't touch it, physical distancing, makes it more difficult to we explore the power of gentle touch in 30 minutes on d,
