Preventing active re-identification attacks on social graphs via sybil subgraph obfuscation
[article]
2020
arXiv
pre-print
Preserved Fulltext
This paper addresses active re-identification attacks in the context of privacy-preserving social graph publication. ...
Active attacks are those where the adversary can leverage fake accounts, a.k.a. sybil nodes, to enforce structural patterns that can be used to re-identify their victims on anonymised graphs. ...
This finding is of paramount importance, as it enables the use of any known anonymisation method ensuring k-symmetry for preventing active re-identification attacks via sybil subgraph obfuscation. ...

Experimental results, obtained on real-life graphs and a large collection of randomly generated graphs, show that our methods effectively prevent attacks from active adversaries with the capability of ...
In our adversarial model we consider an active attacker, who has the capability of altering the structure of the social graph before publication by creating new user profiles and establishing relations ...
Re-identification attacks to social graphs are typically categorised as passive or active. ...
