外包数据隐私保护环境中数据完整性检测协议

摘要

随着大规模云计算数据中心服务器在全球范围内的广泛部署,其低投入,可扩展性强等特点,为这些拥有大数据量的公司或事业单位存储数据提供了便利,并节约了构建IT环境的资金成本,但是在这种数据外包环境下,这必将涉及到信息安全与隐私保护问题.在保证安全性和准确性的前提下,本文提出了基于保护隐私的数据外包存储模型.与数据隐私保护挖掘算法相结合,提出了基于数据通信的数据完整性检测协议,该协议使用数据安全技术,从安全的多角度出发,包括数据传输安全,数据挖掘安全,完整性安全等,使得第三方服务器变得可信.%With the large-scale cloud computing data center server globally deployed,its advantages Such as low cost,strong expansibility etc.provide convenience for those companies or business units with large amount of data,and save the cost of capital on the construction of the IT environment.But in this data outsourcing environment,this will involve information security and privacy protection.On the premise of guaranteeing the safety and accuracy,this paper presents an outsourcing data storage model based on the protection of privacy.Combined with data privacy protection of mining algorithm,it puts forward the data integrity detection protocol based on data communication.The protocol uses data security technology,starting from the angles of safety,including the security of data transmission,data mining safety,integrity,security etc,making the third party server trustful.
