拖拉机数字化设计数据库云存储服务数据安全研究

Research on Data Security of Cloud Storage Service in Digital Design Database of Tractor

目前,在拖拉机设计过程中,由于多数设计部门之间存在缺乏自动化信息交换的手段,设计效率低,难以满足当前设计制造信息化的实时性需求。为了解决这个问题,很多设计企业引入了云设计服务平台,但在信息交换共享的过程中,由于数据拥有者和管理者的分离,会造成数据的安全和知识产权的侵犯问题。为了保护拖拉机数字化设计过程中的图纸和图像的隐私性,提出了一种基于图像退化和复原以及数据分离存储和共享的数据安全隐私保护方法。该方法除了会对拖拉机数字化设计过程中产生的作品图像进行重要信息退化之外,还采用了分离式的数据存储传输形式,将数据信息分离成多个部分,任意一个单一的单元都无法获取完整的信息,实现了数据的双重加密,使加密信息更加安全可靠。对云存储服务数据安全及隐私保护技术进行了验证,结果表明:随着数据规模的不断扩大,通信代价并没有出现过大的变化,并且数据的安全性较高,满足数据安全及隐私保护设计需求。

At present,due to the lack of automated information exchange between the design departments,the design efficiency is low,so it is difficult to meet the real-time requirements of the current design and manufacturing information.In order to solve this problem,many enterprises have introduced the design of cloud design service platform,but in the information exchange and sharing in the process of the separation of data owners and managers,will lead to data security and intellectual property violations. In order to protect privacy in the process of tractor digital design drawings and images,this paper proposed an image degradation and restoration and separation of data storage and sharing data security and privacy protection method based on the method of digital design in addition to the tractor works produced in the process of image degradation are important information,also uses a separate form the data storage and transmission,the data is separated into multiple parts,any single units are unable to obtain complete information,to achieve the double encryption of data encryption,make information more safe and reliable. The cloud storage service data security and privacy protection technology is verified by experiments,the experimental results show that with the expansion of the data scale,the cost of communication and there have been no major changes,and high data security,data security and privacy protection to meet the design requirements.
