Embodiment Construction

[0047]Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] Traditional physical storage has problems such as resource dispersal and storage reliability cannot be guaranteed. Storage virtualization refers to the mapping of various scattered and heterogeneous storage devices into a logical storage space with unified and continuous addressing according to certain strategies, called It is a virtual storage pool and provides the access address of the virtual storage pool to the application system. Storage virtualization improves the reliability and availability of data through technologies such as data mirroring, data verification, and multipathing.

Abstract

The invention discloses a supervisible data privacy sharing method based on end-side cloud collaboration, which aims at data privacy sharing and supervision in an end-side cloud scene and comprises the steps of data cloud storage based on symmetric key encryption and generation of metadata, uplink of metadata based on a distributed key of an alliance chain and data supervision based on searchable encryption. Supervision modes include envelope supervision and unsealing supervision, and the envelope supervision confirms whether a user submits a storage voucher of metadata within a certain time or not under the condition of consensus of all nodes; if unsealing supervision is carried out, a metadata storage voucher of a user is obtained, stored data is decrypted, and a data plaintext is obtained; and the block chain system is used for storing private data of the user, protecting data privacy from being leaked, and realizing supervision under a data privacy sharing condition.

Description

technical field [0001] The present invention relates to the fields of edge computing technology and block chain technology, in particular to a method for sharing certificate privacy based on terminal-edge-cloud collaboration. Background technique [0002] With the opening of the big data era, various industries and regions have invested a lot of manpower and material resources in the construction of data centers, and the application of big data continues to develop and popularize. The scale of various information systems is becoming more and more complex, the amount of data is increasing, and the types of data are increasing. Data forms are also becoming more and more diverse. In the construction of a big data platform, data resources usually include the data of the department, as well as the data of relevant cooperative departments and the public data of the Internet. With the continuous accumulation and use of data, the value of data is also increasing. How to use data sa...
