    It’s not necessary for the person to be the sole target.

    By comparing the persons DNA to 2 or 3 relatives in a database, it’s quite easy to identify whose DNA you have, or at least narrow it down to a few potentials. (E.g. the DNA is from a male that is a cousin of X by the male line and nephew of Y by the female line).
