Digital Gold
How cookies took over the world
Every day, we leave traces behind in the digital world. Thousands of tiny signals about what we read, what we click on, what annoys us, and what we put in our cart. This data is worth its weight in gold. It is collected and evaluated in real time, and traded within a complex ecosystem.
How far can this information travel, and when does it start influencing our decisions faster than we can even realize?
This book gives you what the digital world lacks most: context.
It will explain:
- how data is handled
- why it is so valuable
- how seemingly invisible influence works
- how to build healthy digital habits
- how to move through the digital world consciously
Our everyday lives now unfold on phone and computer screens and through smart devices that generate data. That data affects what we buy, what we believe, who we vote for, and even where we go on vacation. Learn how to protect your digital gold.
About me
My name is David Prochazka. I work in technology, development, and education. For a long time, I have focused on how technology shapes everyday life, from automotive development and artificial intelligence to digital privacy, security, and working with data.
I am writing Digital Gold because the digital world has become a normal part of life, yet most people still do not realize how valuable their data is. My goal is not to scare people. I want to explain, show the connections, and help people make better decisions in the digital environment.
Online privacy is not a luxury for experts. It is a basic skill for modern life.
