Survival guide: how not to «undress» before the network

El Correo, with more than eighty years of history and the largest circulation in the Basque Country, devotes a double-page spread of its Innovación supplement to the phenomenon of involuntary digital exposure. The 24 May 2026 edition tackles the subject from two complementary angles: an in-depth report on the sophistication of modern attacks, and a practical sidebar where my statements lay out the advice for the everyday reader.

The focus of the coverage is not the classic virus or malware, but something quieter: the voluntary handover of personal data in exchange for immediate convenience, and how that information can later be used by companies, insurers, or malicious actors.

My contribution

The free-of-charge trap

The article captures my warning about the business model behind free digital tools. Handing biometric data to a company in exchange for a discount or out of curiosity is giving away your life. A password can be changed if it’s stolen, but your face or your iris are forever: there is no replacement.

Biometric data is irrecoverable

Unlike a password, the iris or the face cannot be replaced if compromised. The piece illustrates this with a concrete example: an insurer could calculate health risks and adjust premiums based on biometric information that the user voluntarily handed over years earlier, without being aware of the future implications.

The verbal password as an analog defense

Faced with AI’s growing ability to clone voices, I recommend establishing secret codes among family members to verify the identity of whoever is calling in an emergency. If a child or grandchild calls asking for money, you have to ask them that secret question only the family knows. It’s the only way to tell whether it’s a person or a machine.

About the publication

El Correo and its Innovación supplement

El Correo is the most widely read newspaper in the Basque Country, published since 1938 in Bilbao and part of the Vocento Group. Its Innovación supplement comes out weekly and covers technology, science, business, and digital transformation across the entire Basque region and Álava. The full edition is available in the supplement’s digital archive.

First coverage in European print press

This appearance marks the first time I have been cited in a European print outlet —specifically in the Basque Country—, at a moment when the debate over digital privacy, AI, and user rights sits at the center of the European regulatory agenda. The coverage comes alongside the entry into force of the European Union’s AI Act and the discussion on digital identity in the context of the FIFA 2026 World Cup.
