Not really. It's only true if the bits are uncorrelated, and you can acquire additional bits of information. I don't see how you can go from "this guy on the internet lives near Albuquerque, New Mexico" to "this guy is Walter Hartwell White, and lives at 308 Negra Arroyo Lane, Albuquerque, New Mexico, 87104" without massive opsec failures.
