More and more banks now ask for additional digital data: selfies, video ID, device information, location data, and behavioral signals.
The explanation is always the same:
“For your security.”
“To prevent data breaches.”
It sounds reasonable.
But something fundamental is shifting.
Banks are quietly moving from financial service providers to custodians of your digital identity.
Where you once were simply a customer, you are now becoming a data profile: how you type, where you log in from, which device you use, how your face moves during verification. This is known as behavioral biometrics. Officially it exists to prevent fraud. In practice, it creates an increasingly detailed record of your existence.
Not because individual institutions are malicious — but because the system itself is evolving this way.
Here’s the paradox: the more data gets centralized, the greater the damage when it leaks.
You can change a password. You can replace a passport. But you cannot replace your face. ou cannot reset your nervous system.You cannot regenerate your behavioral patterns.
Regulation is often cited as justification. Yes, banks are required to identify customers. But regulation calls for verification — not maximal data extraction. That distinction matters.
What we’re seeing instead is a gradual normalization of expansion: extra checks, “smart security,” default opt-ins. No public debate. No clear moment of consent. Just small screens with large consequences.
We’ve already watched this pattern unfold across tech platforms, including AI rollouts by companies like Meta Platforms — features appearing quietly, framed as convenience, powered by continuous data capture.
This isn’t primarily a technological issue. It’s a question of ownership.Who owns your digital shadow?
Privacy is not a luxury. It is sovereignty.And sovereignty rarely disappears overnight. It erodes through forms. Through updates.Through policies labeled “security.”
My personal boundary is simple: I accept financial services. I accept reasonable identification. But I do not accept an open-ended license on my digital existence.
Maybe it’s time we start asking a different question: not what is allowed —but what is proportional?
