How do they get the data, is it just because that Russian network allows scraping?
I had an idea like this before, actually I think it might even work with just descriptions (no photographs needed). Like if you see a stranger on a train - you don't need that many bits of information to identify them. But you need the data of all people living in a city...
- informatimago 10y agoExactly. For a city with 200,000 people you only need 18 bits. For the whole planet, you only need 33 or 34 bits.
- pavel_lishin 10y agoBut you have to select the bits very carefully for that population. If you're playing "Bitwise Guess Who?" against Moscow's population, there are going to be many combinations of bits that result in zero matches (ethnicity: African, hair color: red, eye color: blue, height: 4 feet) and many combinations of bits that result in many matches (ethnicity: Slavic, hair color: blonde, eye color: blue, height: 5'8")
