摘　　要：针对云计算环境中机器学习方案存在的安全和隐私泄露问题,提出了一种新的基于云计算的隐私保护支持向量机分类方案.用户端使用二维滞后复Logistic映射和Paillier加密方案将明文数据集加密后上传至模型服务器后,模型服务器通过协议与云服务器协同计算分类结果并返回至用户端.实验结果表明该方案能够在半诚实安全模型下安全计算的同时保护各参与者隐私,且精度较高.Aiming at the security and privacy leakage problems of current machine learning schemes in cloud computing environment,a classification scheme of privacy preservation support vector machine based on cloud computing is proposed.The client terminal uploads the plaintext dataset to the model server with two-dimension lag complex Logistic mapping and Paillier encryption scheme.Then,the model server collaborates with the cloud server through the protocol to compute classification results and return them to the client terminal.The experiments show that this scheme can protect the privacy of each participant in the semi-honest security model while the security computation is performed,the accuracy is comparatively high.
