Fascinating: from a very quick scroll it is surprising to see how much traffic is to do with banks.

Wilmington Trust, Bank of Utah, Wells Fargo, “UMB Bank” (?), US Bank. Is it really the case that a quarter of US air traffic is rich people in suits who are too good for Zoom? :)

In some countries, this is still true, with the addition of even your salary being public information.

I didn't know about the salary, what country is that? I'm curious

In Sweden, any document touched by the government is by default open to the public, as an anti-corruption, pro-democracy measure.

Of course, your tax forms are documents touched by the government, in which your declared income is stated.

Ok, so how long before someone looks at those flights, times and maps out your exact house address?

Scrambling the time a random amount each flyover could help?

Biasing by a constant amount might help.

The thing about unbiased random noise is that it cancels itself out! And for the most part, we can compute exactly how many data points are needed to achieve a particular level of precision in the result.

If you add a laser pointer you'll effectively get yourself arrested within a few hours. Aircraft get laserd relatively often and it's dangerous to the pilots. We report it to air traffic control with an estimated location, they then coordinate with the police. Common practice is to turn off exterior lights when lasered, because it's just bored people with a laser pointer and they can't aim when the plane has no light…

Often? Hopefully it's just kids with no concept of the dangers involved. I don't understand why an adult would do such a thing.

The FAA publishes the number of reported incidents: https://www.faa.gov/about/initiatives/lasers/laws

Norway is one such country ( https://www.bbc.com/news/magazine-40669239 ) but I think some others in the Nordics also does the same, not sure exactly which though and Google is not being very helpful this evening.

It's not exactly true that your salary is public -- what's public is your taxable income, taxable wealth, total estimated tax, birth year and postal code. Various deductions apply to the income which makes it non-straightforward to deduce a person's actual income, and as for taxable wealth the minimums are high enough and deductions are substantial enough (especially if you own a home) that a lot of people with wealth much greater than zero will be listed with a taxable wealth as zero.

If you add a laser pointer, you effectively built a low cost anti aircraft weapon. Very cool

Get arrested?

I was thinking it would be good for rebels in Africa or the Middle East who get attacked by nation state actors.

This is a low cost anti air deterrent and monitoring system, that can operate remotely, and autonomously.

Don’t poor people have the right to not be bombed?

Useful idea for usage: Point a WiFi-dish/antenna towards the plane and gather WiFi & Bluetooth MAC addresses for all the passengers. Now you can make statistics about the number of passengers, how long /often they travel ++ good information if you want to trade stocks in airplane companies. You can direct the antenna precisely because you have the image recognition in addition to GPS.

MAC address randomization makes this harder.

It's impossible given how fast planes fly

Planes don't fly that fast. The body of the aircraft would tend to shield the signals though.
