i already know her. it's adeena. 30 years old, lives in cologne, originally from cedar. trained in communication 1st and now studies business administration. she told me all of that 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 post she likes and what she shares with her friends, her comments, the people she sent 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, maybe 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 pro fall 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 your e mail 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 may be 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 delete and cookies and browse history regularly enough to serve anonymously to people allowed us to use their profiles to tasteless. oh,

just to give eva 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, oh oh, which was a for the fists was i tried to be careful and mindful of which information i share . so i really try to protect my personal data as much as i can when i'm online. observe, 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, including apps that belong to tech giant meta and google, which are can i add in 40? does i see the advantage more of google and facebook using my daughter to make recommendations and sure me heads didn't come 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 of the calls room institute of technology in germany. together with a colleague, he's going to take a look at the digital tracy's jessica and mark leave online and see which can be used for individualized ads. most options, everything that you have, i'm sticking only. you'd really have to invest a lot of time and energy to browse the internet anonymously. i think the average consumer and corporate to stop the data from being collected guide the dots. i'm not too empty. jessica regularly checks this news web site. the page saves so called cookies. small, they to package is a unique identifiers on her computer. we ask the marketing experts to take

a closer look at the new sites. 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 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 online. or the result is yes, no other user transmits 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 la 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 still unsure. so for now, he adds the laptop to his cart and hurts 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 certain times 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 marty egless feed. they select the criteria accordingly as a big, big event since the lease mileage we consider the location to karlsruhe and colorado. army age setting. oscar and we can add male for gender, ultimately jenkins. yeah. to say how old is mister igloo exhausts? and the swans once is sold, i think we should be good with the age bracket. 18 to 22. right. and equally does

that. and we know that he likes football and supports manchester united as interest so we can add that to interest does from align stern household investment. we also know that he was born in guatemala, were to mala comp, which we can add as well can the on the uneven. they are ready to publish their right. it's the moment of truth. will the ad appear amongst facebook feed? it does next to photos imposed by his friends as the ad. but mark eagerly. it's not very concerned. let's say all night long business, sean, are you always 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. does us relative one and 200. 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 benz can bargain. if we no longer had cash, we wouldn't be able to pay anonymously any more. we'd always leave down to traces that would be analyzed and used to manipulate. and so i'm in the money put these days, people increasingly pay even small sums with card oh, 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 mm hm. and business steady payment daughter. this aspect of confirmations are off. you can create a profile about someone and say this person tends to do this. so let us get on with payment daughter, you can see what they actually do, what they're willing to spend money on the account. it's like a promise where profiles are confirmed or questions. it's sort of like putting them to the taste of people. if i've got payment data, i know what that person has really like 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 assign 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 are suitable to me looked at it as a school due to kept engine, speed of income, more dates, i mean, more accurate profiles. so how predictable do we want to be ah,
