Embodiment Construction

[0041] An exemplary embodiment of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown, it is understood that the disclosure can be implemented in various forms without limitation. Instead, these embodiments are provided to be more thoroughly understood to disclose the present disclosure, and can communicate the scope of the scope of the present disclosure to those skilled in the art.

[0042] In a distributed storage system based on block chain, for example, in a distributed storage system based on the league chain, some nodes have idle storage space, which can be stored for other users with storage requirements. Service, that is, a storage node, thereby obtaining a certain interest. For example, a user releases a file storage requirement. Broadcasting through the block chain, the node with idle storage space can accept this storage task, store the user's f...

Abstract

The invention discloses a data possession certification method, device and readable storage medium, belonging to the technical field of the Internet. The method includes: the first node receives the challenge data corresponding to the target file sent by the second node, the challenge data includes the feature value of the target file and a first random number satisfying a preset condition, and then, according to the feature value and the first Find the corresponding fragment in the target file with a random number, and use the found fragment as the target fragment, and then, according to the target fragment and the preset one-way function, obtain the proof data corresponding to the verification value of the target file , and send the proof data to the second node as the workload proof of the first node. In this way, the second node can verify whether the first node holds the target file according to the proof data and the verification value of the target file, thereby preventing the storage node in the blockchain system from having workload cheating.

Description

Technical field [0001] The present invention relates to the field of Internet technologies, and more particularly to a data holding a proof method, apparatus, and readable storage medium. Background technique [0002] Informatization era, data storage is critical. Currently, data storage is mainly divided into local storage and cloud storage. Cloud storage is a centralized service, the server control rules and dominant, once the service is stopped, the stored data is not available. In addition, cloud storage services provide services through the construction of a professional data center, cost is extremely high, in the business field, the company's large data light storage cost is a small expenditure. Based on this, researchers have proposed a shared storage network based on block chain technology. The block chain and the shared economy are the current hotspots and leading trends. As the amount of information increases, more and more users have data storage requirements, and many...
