Privacy Preserving Models of k-NN Algorithm

Conference paper
Part of the Advances in Intelligent and Soft Computing book series (AINSC, volume 95)


The paper focuses on the problem of privacy preserving for classification task. This issue is quite an important subject for the machine learning approach based on distributed databases. On the basis of the study of available works devoted to privacy we propose its new definition and its taxonomy. We use this taxonomy to create several modifications of k-nearest neighbors classifier which are consistent with the proposed privacy levels. Their computational complexity are evaluated on the basis of computer experiments.
