Typically, the large amount of data we provide (especially on social networks) is used for advertising purposes, achieving ever greater precision by reaching the right person at the right place at the right time.
However, big data has also enabled other types of data use and initiatives for other purposes, such as the fight against the covid-19 pandemic. Geolocation data or contacts with other people allow the design of systems aimed at containing the pandemic, making it possible to isolate affected individuals and their contacts, and to issue alerts in those places with the highest probability of contagion.
Another new use of data, for example, in the financial system, is to use algorithms to classify the expenses of a bank account into different categories, making it easier for customers to easily and quickly visualize their average spending on food, services, clothing, supermarkets, etc. This in turn allows the system to detect unusual expenses and alert customers so that they can verify if it is an error.
As can be seen, the uses of this data can be very varied, which is why it is essential for society to become increasingly aware of the personal data it provides and the possibility of large companies making use of it. Every time we browse a web page, through the so-called cookies, we are sharing a lot of information (from where we are accessing, on what days and at what times, what information we are looking for and is of interest to us, what purchases we actually make, how we pay, and much more).
