Abstract

The invention provides a security method of personal data in cloud storage. The security method includes, in the process of uploading of local data, encrypting the data by means of hardware encryption and then uploading the same to a cloud storage system so as to keep the data stored in the cloud storage system encrypted; in the process of downloading the data to a local device from the cloud storage system, decrypting the data by means of hardware decryption and then storing the same to the local device. According to the technical scheme, encryption and decryption of client files in cloud disks are independent of network and cloud computing systems, all the operations of encryption and decryption are completed on the client side, technical bottleneck and complicated application environment to implementation of data security measures on the cloud side are avoided, and the security method has the advantages of high safety, reliability and usability and the like.

Description

technical field [0001] The invention relates to the field of cloud storage and data security, in particular to a method for cloud storage of personal data security. Background technique [0002] At present, cloud computing (including cloud storage) has become a recognized development focus of the global ICT industry, and data leakage is the most worrying issue of cloud storage to the public, and it is also a huge obstacle blocking the commercialization of cloud computing. Many threats may lead to the loss and leakage of customer cloud disk (network disk) data, such as hacker attacks, etc., and further raise the issue of customer trust in cloud storage services. In addition, according to relevant data leakage investigation reports, 48% of data leakage is due to malicious insiders, such as management and maintenance personnel of cloud computing service providers, supplier employees, and so on. [0003] From a technical point of view, due to the problems of service networking,...
