Inference attacks and control on database structuresTurkanović, Muhamed (Avtor) Welzer-Družovec, Tatjana (Avtor) Hölbl, Marko (Avtor) inferenceattacksdatabasesecuritysemanticsToday’s databases store information with sensitivity levels that range from public to highly sensitive, hence ensuring confidentiality can be highly important, but also requires costly control. This paper focuses on the inference problem on different database structures. It presents possible treats on privacy with relation to the inference, and control methods for mitigating these treats. The paper shows that using only access control, without any inference control is inadequate, since these models are unable to protect against indirect data access. Furthermore, it covers new inference problems which rise from the dimensions of new technologies like XML, semantics, etc.20152017-08-09 08:32:27Znanstveno delo67262sl
