In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The embodiment of the application provides a block chain-based secure distributed cloud storage service implementation method and a corresponding scheme, a secure distributed cloud storage is constructed through a block chain technology and a distributed storage protocol stored on a block chain, a user can contribute to temporarily redundant hard disk space to earn reward, and extra space can be obtained through reward payment.
Fig. 1 is a schematic flow chart of a method provided in an embodiment of the present disclosure. As shown, the method comprises:
s101, receiving data sent by a user through a communication interface of a block chain;
s102, encrypting the data of the user through the public key of the user to obtain encrypted data;
s103, sending the encrypted data to a cloud storage for storage, wherein the cloud storage is built through a plurality of disk spaces rented by the users.
The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and forged. Although the underlying technology of blockchains has been developed for many years, it has not been possible to achieve effective application in a particular scenario.
According to the embodiment of the invention, the blockchain is provided with the intelligent contract for managing the user data and the distributed storage protocol, and the intelligent contract is an automatically running script which is deployed on the blockchain and has the characteristic of being transparent to the public due to the fact that the intelligent contract is arranged on the blockchain. A user presets rules through an intelligent contract so as to write data into a block chain and acquire data browsing permission, and disclosure of privacy information is avoided to a great extent. Of course, the smart contracts are not the only implementation manner of the present application, and are set correspondingly according to different blockchain platforms, such as an ethernet house, a super book, and the like.
According to the embodiment of the invention, a user can install a blockchain client on the equipment, and then configure the disk directory for leasing and the disk space size for leasing according to the indication of the client. The method comprises the steps of establishing connection between a user and a blockchain through a blockchain client, and constructing a distributed cloud storage based on a distributed storage protocol in the blockchain, wherein the cloud storage is called as the cloud storage for convenience of description.
According to a specific embodiment of the present invention, before step S101, the user needs to pay a certain prepaid amount to the blockchain, and it is understood that the prepaid amount may be a certificate in the blockchain or a currency circulating in the real world. After the user pays the prepaid funds, the intelligent contract for the blockchain opens a communication interface to the user to communicate with the blockchain.
It is to be understood that the order between step S101 and step S102 is not particularly limited in the embodiment of the present invention, that is, the main body of the data of the encrypted user is not particularly limited in the embodiment of the present invention. The user's own device may encrypt the data through the public key, or the user uploads the data to the blockchain, and the blockchain encrypts the data through the user's public key. All data stored in the cloud are encrypted by using the user public key, so that the user can only see the data through the private key.
According to an embodiment of the present invention, in step S103, the sending the encrypted data to a cloud storage for saving includes: and sending the encrypted data to a cloud memory, and enabling the cloud memory to perform redundant backup and fragmentation storage on the encrypted data according to a distributed storage protocol. Data are stored in the cloud storage through redundant backup and fragmentation, and the downloading of the data is not influenced when part of nodes are damaged. High download speed and high availability of 99.99999% are provided by data slicing.
According to an embodiment of the present invention, after the block chain instructs the cloud storage to store the encrypted data, the method further includes: and sending the hash value of the encrypted data to the user so that the user verifies the integrity of the encrypted data. When the data of the user is encrypted by using the blockchain, the hash value of the encrypted data is sent to the user, so that the user can verify the integrity and the availability of the encrypted data stored in the cloud storage through the hash value. Of course, verifying the integrity and availability of the encrypted data may also be implemented by intelligent contracts of blockchains, and embodiments of the present invention are not particularly limited.
Correspondingly, the intelligent contract of the block chain receives information that whether the encrypted data is complete fed back by the user; if the encrypted data is complete, sending rewards to users renting the disk space through an intelligent contract of the block chain; and if the encrypted data is damaged, returning the prepayment of the user to the user through the intelligent contract of the block chain.
According to the specific embodiment of the invention, the storage mode of the encrypted data in the cloud storage comprises redundant backup and fragment storage, and the encrypted data is managed by setting an intelligent contract for managing redundant backup information on a block chain, specifically:
the intelligent contract of the block chain receives redundant backup information sent by a cloud memory, mainly the redundant backup quantity of the encrypted data, and determines whether a new disk space (new equipment) is added or not according to the redundant backup quantity to store the redundant backup of the encrypted data; or whether to delete a partial redundant backup of encrypted data based on the number of redundant backups.
It is emphasized that the main processes of storing the data of the user in the cloud storage are all recorded in the blockchain, and the recorded information mainly includes the process of storing the data of the user in the cloud storage, and the process of processing the redundant backup stored in the cloud storage by the intelligent contract of the blockchain. If the problems of data loss of the user and the like occur, the tracing can be carried out through the block chain.

a memory communicatively coupled to the at least one processor; wherein the content of the first and second substances,
the memory stores instructions executable by the at least one processor to enable the at least one processor to:
receiving data sent by a user through a communication interface of a block chain;
encrypting the data of the user through the public key of the user to obtain encrypted data;
and sending the encrypted data to a cloud storage for storage, wherein the cloud storage is built through a plurality of disk spaces rented by the users.
