The Sapienza computer scientists say Wi-Fi signals offer superior surveillance potential compared to cameras because they're not affected by light conditions, can penetrate walls and other obstacles, and they're more privacy-preserving than visual images.

[…] The Rome-based researchers who proposed WhoFi claim their technique makes accurate matches on the public NTU-Fi dataset up to 95.5 percent of the time when the deep neural network uses the transformer encoding architecture.

People willingly provide enough tracking of themselves already

While this could have military applications, the need to generate a profile of the person you want to track makes this less of a concern for your average “carries a phone everywhere” person

Tech companies are always foaming at the mouth to get more data. Yes they know who you are but what do you think, how do you feel, how do you move? The only way to go is to get richer data. This satisfies that addiction. You really think mark Zuckerberg won’t use this against you if he can?
