There is nothing inherently wrong with contact tracing apps, but only in the context of stopping the spread of Covid-19. For every other purpose in the future, without superlative cryptography, it will become a horrendous breach of privacy and a pathway to exfiltrating your personal data. Not just in terms of hacking, but in terms of government intrusion and surveillance.
Give Norway credit for shutting theirs down. I wonder how many other nations will follow suit?
If any nation wants an actual pandemic contact trace app, that is hack proof and utilizes a “zero-knowledge” approach, send us a note and we can install the Helix22 SDK to make it happen. INFO@BLAKFX.COM
fyi, we are not holding our breath waiting for the call.
