A bit of analysis undertaken by scientists at the Universidad Carlos III de Madrid (UC3M) and the Graz University of Technology (Austria) exhibits that an advertising marketing campaign on Facebook can goal a specific particular person, with the marketing campaign being based mostly solely on 4 distinctive pursuits assigned to the person by the social community.

Personalisation of on-line advertising based mostly on our search historical past and preferences just isn’t a new phenomenon, because it has been growing over a few years. However, this new study, offered at a world scientific convention (ACM Internet Measurement Conference), highlights the truth that adverts can be customized and despatched to a specific particular person through the Facebook advert platform utilizing simply the person’s pursuits.

This reveals a potential privateness situation, in response to the workforce of researchers, made up of José González-Cabañas, Ángel Cuevas, Rubén Cuevas, Juan López-Fernández, and David García. “It allows hyper-personalized ads to be created that may have a greater effect on the user who receives them,” explains Ángel Cuevas, from the UC3M’s Telematic Engineering Department.

This situation exposes customers to new dangers that come up from the mix of pursuits. There are two forms of knowledge inside this framework: firstly, knowledge that immediately reveals a person’s id (comparable to their ID No., , or e-mail handle), which require the person’s consent to ensure that corporations to make use of them, and secondly, knowledge that can’t be attributed to a specific person, comparable to their pursuits, gender, or age. “What if we can identify an individual using Facebook without their permission just by combining their interests?” the researchers ask.

From a theoretical perspective, these scientists have demonstrated that little or no person info, solely 4 uncommon and specific pursuits, make them distinctive in a database consisting of billions of customers. Previous research have pointed to this, nonetheless, they labored with a a lot smaller database of customers, of about a million customers. This capability to section customers in a very specific method known as “nanotargeting” by the researchers and in sensible phrases, it has been demonstrated that this can be executed on Facebook with virtually zero price. In different phrases, reaching a person person among the many 2,800 million lively profiles on the social community is feasible.

To do that, researchers performed an experiment: they created 21 advertising campaigns that have been meant to achieve three of the authors of this work. “On the one hand, we are the advertiser on Facebook and, on the other, the advertisement is targeted at each of us. We built a model to see how many interests we would need in order to reach a specific person with a high probability, then we validated it using the campaigns,” explains one other researcher from the UC3M who wrote this work, José González Cabañas. “By combining five random interests, the ad did not reach the chosen user. However, the probability of success increased as the number of interests rose to 7, 9, etc. We saw that in the real experiment, 20 and 22 interests guaranteed success. However, only four interests are required, if they are very rare and specific interests.”

From a advertising and marketing perspective, this selection may be extraordinarily helpful for corporations that wish to create hyper-personalized campaigns for his or her clients. However, from a person safety perspective “what we are actually asking the advertising platforms is that they take steps that prevent nanotargeting from being carried out. In this sense, the advertising platform should, in accordance with parameters defined by the advertiser and estimations provided by the platform, ensure that the advertisement may reach a group of at least 1000 users, for example, in order to protect an individual’s privacy and avoid nanotargeting,” concludes Ángel Cuevas.
