Is that really you?

Identity poisoning by fake-named account is caused not only by identity theft but also by valid accounts with impersonated screen-names. From users' perspective, screen-name is an identifier of other users without obtaining any credential information. To prove the originality of a user without revealing identifier information, we focused on linkability, an element of online identity. Not only the extent of linkability but also its direction assures the originality. We assumed that the existence of bi-directional link(s) among two or more entities shows the tight relationship thus there is possibility of being identified as the same users'. As a result of our experiment, on Twitter, identified pairs are obviously filtered from suspicious pairs only based on direction of links.
