Nearly every action in our lives leaves digital traces: We carry our mobile phones, being locatable all the time, we shop on the web, providing taste fingerprints to myriads of recommender systems, and we carry Smart Watches, measuring our body signals to monitor our health. While currently, this data is scattered across many distinct places and provider across the internet, we can subsume that an alter digital ego exists, which is defined by all the data that there is persisted on the web, is that is tied to our person. As over time, this alter ego reflects ever more details of our movements, interactions, and moods, this image becomes more and more precise, eventually representing us fully. As digitalization happens likewise to aggregate societal institutions like companies, cities or countries, our digital alter ego becomes the counterpart for real world transactions. For these transactions, it becomes less important of who we really are, it's more important what our data says about us.
