A P2P Based Usage Control Enforcement Scheme Resilient to Re-injection Attacks

Abstract : Existing privacy controls based on access control techniques do not prevent massive dissemination of private data by unauthorized users. We suggest a usage control enforcement scheme that allows users to gain control over their data during its entire lifetime. The scheme is based on a peer-to-peer architecture whereby a different set of peers is randomly selected for data assignment. Usage control is achieved based on the assumption that at least t out of any set of n peers will not behave maliciously. Such a system would still suffer from re-injection attacks whereby attackers can gain ownership of data and the usage policy thereof by simply re-storing data after slight modification of the content. In order to cope with re-injection attacks the scheme relies on a similarity detection mechanism. The robustness of the scheme has been evaluated in an experimental setting using a variety of re-injection attacks.
