Using fully homomorphic encryption scheme, we construct fully homomorphic encryption scheme FHE4GT that can homomorphically compute an encryption of the greaterthan bit that indicates 𝑥 > 𝑥 ′ or not, given two ciphertexts 𝑐 and 𝑐 ′ of 𝑥 and 𝑥 ′, respectively, without knowing the secret key. Then, we construct homomorphic classifier homClassify that can homomorphically classify a given encrypted data without decrypting it, using machine learned parameters. Read More
