Embodiment Construction

[0062] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0063] like figure 1 As shown, a distributed cloud storage data access method provided by the present invention includes the following steps:

[0064] Implement clustering management for cloud data distributed on each node of the network, and the cluster center node uses Bloom filter to record the data characteristics of cloud data stored by each cluster member;

[0065] The data requesting node retrieves the target data from the cluster center node by using the data feature, and uses the cluster member that stores the target data as the data providing node, and the two parties use the exchanged address public parameters to jointly generate the public key address for payment;

[0066] The data providing node generates a partially blinded mes...

Abstract

The invention relates to a distributed cloud storage data access method and a data service system, data distributed and stored on each network node is subjected to clustering management, a cluster center node records data features published by cluster members by a bloom filter as index information, the cluster center node provides query service when a user needs to access the data, and the user can access the data. Target data is directly transmitted to a user by the positioned cluster members, and data query and data storage services are isolated, so that catastrophic loss caused by single-point failure after all data are stored in a central node is avoided; the data security can be ensured by taking the unidirectional data feature as the data index, and any third party cannot know the specific data object requested by the user; and meanwhile, a partial blind signature algorithm is adopted for constraining transaction parameters of consensus between two service parties, so that the two parties can autonomously complete transfer and target data access services by taking signatures as transaction vouchers.

Description

technical field [0001] The invention relates to the field of cloud storage applications, in particular to a distributed cloud storage data access method and a data service system. Background technique [0002] Cloud storage is a complex storage resource pool system developed from the concept of cloud computing. Cloud storage integrates a large number of different types of storage devices in the network through application software to work together through cluster applications, distributed file systems, etc., and through these application software and their respective interfaces, jointly provide users with intensive data storage and With the shared access function, users can flexibly use cloud storage space or accept cloud data access services and pay as needed. The rapid development of cloud computing in recent years has attracted more and more users to deploy a large number of applications and data to the cloud platform. [0003] At present, distributed storage technologi...
