A Fuzzy KNN Classifier for Confidentiality of Cloud Tasks

Data security is the keystone of the cloud computing. In this paper, a fuzzy KNN classifier has been proposed to classify data into three classes of confidential, private and public. In other hand, different data encryptions are needed due to their different confidentiality levels, therefore RSA is used to encrypt confidential data, AES for private data and not any encryption is used for public data. At the end, proposed method and simple KNN method has been compared to each other to prove high efficiency of our method.
