Problems solved by technology

[0003] However, the existing method of using third-party auditors to audit hybrid cloud data, third-party auditors may come into contact with actual data related to user privacy during the hybrid cloud data audit process, and user privacy lacks better protection
Moreover, for a large number of audit requests at the same time, it takes a lot of time for the third-party auditors to process the audit tasks, the audit process is relatively inefficient, and the calculation and communication costs are relatively large

Embodiment 1

[0071] figure 1 A flow chart of a hybrid cloud data audit method provided in Embodiment 1 of the present application is given. The hybrid cloud data audit method provided in this embodiment can be executed by a hybrid cloud data audit device, and the hybrid cloud data audit device can use software and / or hardware, the hybrid cloud data audit device may be composed of two or more physical entities, or may be composed of one physical entity. Generally speaking, the hybrid cloud data auditing device is a server of a third-party auditor.

[0072] In the following, a third-party auditor is used as an example to perform the hybrid cloud data auditing method for description. refer to figure 1 , the hybrid cloud data audit method specifically includes:

[0073] S110. When the user end stores the original data and the label information of each block file of the original data to the hybrid cloud, receive the corresponding audit metadata sent by the user end;

[0074] S120. Receive a...

Embodiment 2

[0131] On the basis of the above examples, Figure 7 It is a schematic structural diagram of a hybrid cloud data audit system provided in Embodiment 2 of the present application. refer to Figure 7 , the hybrid cloud data audit system provided in this embodiment specifically includes: a receiving module 21 , a challenge module 22 , an audit module 23 and a verification module 24 .

[0132] Wherein, the receiving module 21 is used to receive the corresponding audit metadata sent by the client when the client stores the original data and the label information of each block file of the original data to the hybrid cloud;

[0133] The challenge module 22 is configured to receive the audit request sent by the client, and send challenge information to the hybrid cloud based on the audit metadata and a preset verification method in response to the audit request;

[0134] The audit module 23 is configured to receive the audit information correspondingly generated by the hybrid cloud ba...

Embodiment 3

[0139] Embodiment 3 of the present application provides an electronic device, referring to Figure 8 , the electronic device includes: a processor 31 , a memory 32 , a communication module 33 , an input device 34 and an output device 35 . Memory 32, as a computer-readable storage medium, can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the hybrid cloud data audit method described in any embodiment of the present application (for example, receiving module, challenge module, audit module and verification module). The communication module 33 is used for data transmission. The processor 31 executes various functional applications and data processing of the device by running software programs, instructions and modules stored in the memory, that is, implements the above-mentioned hybrid cloud data audit method. The input device 34 can be used for receiving inputted numerical or character informa...

Abstract

The embodiment of the invention discloses a hybrid cloud data auditing method and system, an electronic device and a storage medium. According to the technical scheme provided by the embodiment of the invention, the corresponding auditing metadata sent by the user side is received, the auditing request sent by the user side is received, the challenge information is sent to the hybrid cloud based on the auditing metadata and the preset verification mode in response to the auditing request, and the auditing information correspondingly generated by the hybrid cloud based on the challenge information is received; wherein the auditing information comprises a data certificate and a label certificate corresponding to the label information, the data certificate is used for recording verification information of the original data, the auditing information is verified by using a preset verification mode, a corresponding auditing result is generated, and the auditing result is fed back to the user side. By the adoption of the technical means, integrity auditing of the original data can be achieved, a third-party auditor is prevented from making direct contact with the original data for auditing, user privacy is protected, and leakage of the user data in the auditing process is avoided.

Description

technical field [0001] The embodiment of the present application relates to the technical field of cloud storage, and in particular to a hybrid cloud data audit method, system, electronic device, and storage medium. Background technique [0002] As a development trend of storage technology, cloud storage provides convenient and low-cost mass storage services for cloud computing. At present, the common cloud storage services mainly include public cloud, private cloud and hybrid cloud. Among them, the hybrid cloud combines the advantages of public cloud and private cloud, allowing users to more flexibly and personalized collocation, so as to achieve the purpose of saving money and security, so it is favored by the majority of cloud storage users. In order to ensure the integrity and security of hybrid cloud data storage, users need to audit hybrid cloud data. In order to reduce the user's burden, a third-party auditor is introduced to audit the hybrid cloud data according to...
