1 bit = IDs 1/2 of all results
When you have a sample population to make a random selection from, 1 bit of information is enough to cut that population in half.
2 bits cuts your possibilities in half twice.
3 bits cuts your possibilities in half 3 times.
The general formula for bits of information is:
Where “I” is information, measured in bits, and “p” is the probability of a random selection being identifiable.
