A REVIEW OF PRIVACY-PERSERVING KNN CLASSIFICATION PROTOCOL OVER ENCRPTED RELATIONAL DATA IN THE CLOUD

Cloud computing, secure analysis on redistributed encrypted data is a noteworthy subject. As an every now and again utilized inquiry for online applications, k-nearest neighbors (k-NN) calculation on encrypted cloud data has gotten a lot of consideration, and a few answers for it have been advanced. Nonetheless, most existing plans accept the question clients are completely trusted and all inquiry clients share the all out key which is utilized to encrypt and decrypt data proprietor's redistributed data.
