On an analog matter, it reminds me the day I asked my boss: "what is the strongest way to backup things?". Short answer: engrave data on a stone...

So huge paradox of digital life: 1/ you can replicate data infinitly without any error...but each storage taken indivudually is weak...really weak 2/ you can secure access easily with cryptographic algorithms...but anyone who solves/finds a way to break it, the security of all data in the world is comprimised (the best example is RSA, which is not recommended anymore)

Thanks for your thought and anyway: if you can't protect data, don't collect it 🙂
