K-Isomorphism: Privacy Preserving Network Publication against Structural Attacks

Summary: Proposes k-isomorphism as the necessary-and-sufficient privacy model against structural attacks on graphs (NodeInfo/LinkInfo). NP-hard; develops efficiency techniques and a compound vertex ID for multi-release privacy; validated on HEP-TH, EUemail, LiveJournal, showing symmetry aids anonymization while preserving utility.
