Browser Fingerprints - Cookies are no Longer Important

The companies that manage advertising seek to identify their potential customers thanks to their browser fingerprints. Do you know what they are?

We all know that cookies are text files made up of tiny bits of data, which are stored on a web browser. Thy leave a trail like crumbs of bread that point all the roads we have traveled over the network. In some way, it is the piece that gives us away and that tells services, platforms and advertisers who we are.

Surely it has happened to you that you enter an online store and look for a product. From that moment, only ads appear that offer you models and offers that have to do with that search . That’s thanks to cookies, but what would happen if those cookies were not enough in the future? What if advertisers want something more defining and identifying each user, such as a browser fingerprints?

The fingerprint of a browser is a figure that is not new. Many companies have now begun to understand what its true potential is. It is not that our finger is digitized online. Or that they can know when we reach their platform to buy or consume a product. It is a unique code that identifies our browser and offers a quantity of data that could allow any advertiser, or company, to fine-tune who is behind each browsing history.

Imagine that a company could know what are the fingerprints of the browsers that we use the most. With info about operating systems, devices and any other data that would be obtained from it. Undoubtedly, we are facing a much more invasive method than the good old cookies way.

What data does the browser fingerprints contain?

You might think that information such as that provided by our browser does not have much scope. But it is not. The fingerprint of the browser can trace a complete profile of the device from which we are working. From hardware to software, without forgetting to display configuration and even the type of font that we have configured. The method to create that browser fingerprint is as simple as assigning us a code that identifies us from that moment. Like a unique barcode that belongs to us and with which they will from that moment know all our activity.

With this information from the browsing history, the products we are looking for, the interests we show according to the sites we visit, etc., plus the collation of personal data they may have about us, would allow a company to fine-tune with millimeter precision and focus your advertising messages at an almost granular level. Segmentation by types of clients would reach such a degree of effectiveness that it would far exceed cookies .
