In the above operating environment, according to the first aspect of the present embodiment, a method for distributed storage of data based on a blockchain is provided, and the method is implemented by the blockchain server 200 shown in fig. 2. Fig. 3 shows a flow diagram of the method, which, with reference to fig. 3, comprises:
s302: the method comprises the steps that a block chain server receives data sent by first terminal equipment, wherein the first terminal equipment is a node in a block chain; and
s304: the block chain server stores the data in a distributed manner in a plurality of second terminal devices, wherein the second terminal devices are further nodes in the block chain, and the first terminal devices and the second terminal devices can directly communicate by multiplexing cell resources.
As described in the background section above, the 5G network is a fifth generation mobile communication network, and its peak theoretical transmission speed can reach 10gb per second, which is hundreds of times faster than the transmission speed of the 4G network. And the terminal device can directly communicate by multiplexing cell resources (D2D protocol in 5G technology) to provide other terminal devices with the required resources, information and other content, etc. The blockchain has the advantages of decentralized distributed data storage, information which can not be forged and falsified, automatic time stamping during data storage, transparent transaction and the like. Therefore, the 5G technology can be combined with the block chain to perform decentralized data storage, and after the super-large files are uploaded rapidly, the super-large files are stored in each node in a distributed mode through the block chain technology. Meanwhile, the nodes can directly communicate through multiplexing cell resources (D2D protocol), and further, data can be rapidly transmitted and acquired. However, a distributed storage method capable of combining D2D technology and block chain technology for data is lacking.
In view of the above problems in the background art, as shown in fig. 2, the data transmitted by the first terminal device 110 is first received by the blockchain server 200 in the present embodiment. Where the first terminal device 110 is a node in a block chain. The data may be, for example, but not limited to, a movie file, a short video, picture information, or other data. The blockchain server 200 then distributively stores the data in a plurality of second terminal devices (e.g., second terminal devices 120 and 130). Wherein the second terminal device 120 and 130 is a further node in the block chain and the first terminal device 110 and the second terminal device 120 and 130 may communicate directly over multiplexed cell resources. I.e. the first terminal device 110 and the second terminal devices 120 and 130 are each configured with D2D protocols. The first terminal device 110 and the second terminal devices 120 and 130 may be mobile terminals (mobile phones, ipads) or computer terminals.
Thus, in this way, terminal devices configured with the D2D protocol are added to the blockchain, such that each terminal device becomes a node of the blockchain. In the case where the first terminal device 110 wants to store data, the data may be sent to the blockchain server 200, and the blockchain server 200 stores the data in a distributed manner in a plurality of second terminal devices (e.g., the second terminal devices 120 and 130). Therefore, after the terminal device configured with the D2D protocol can quickly upload data to the blockchain server 200, the blockchain server 200 stores the data in other nodes in a distributed manner by using the blockchain technology. Meanwhile, the nodes can directly communicate through multiplexing cell resources (D2D protocol), and data which are stored on other nodes in a distributed manner can be quickly and efficiently acquired. Therefore, the problem that a distributed storage method capable of combining a D2D technology and a block chain technology for data is lacked in the prior art is solved.
Optionally, the operation of the blockchain server to distributively store the data in the plurality of second terminal devices includes: the block chain server generates a pair of public and private keys corresponding to the data; the block chain server encrypts data by using the generated public key; the block chain server stores the encrypted data in a plurality of second terminal devices in a distributed manner; and the block chain server sends the private key to the first terminal equipment.
Specifically, the blockchain server 200 first generates a pair of public and private keys corresponding to the data, and performs encryption processing on the data using the generated public key. The blockchain server 200 then distributively stores the encrypted data in a plurality of second terminal devices (e.g., the second terminal devices 120 and 130). And the blockchain server 200 sends the private key to the first terminal device 110. Therefore, in this way, only the user having the private key can browse the data distributed and stored in the plurality of second terminal devices (for example, the second terminal devices 120 and 130), and the privacy of the data distributed and stored in the plurality of second terminal devices (for example, the second terminal devices 120 and 130) is guaranteed.
Optionally, the method further comprises: the block chain server performs hash operation on the data; and the block chain server stores the hash values obtained by the operation in a distributed mode in a plurality of second terminal devices.
Specifically, the blockchain server 200 performs a hash operation on the data, and then the blockchain server 200 distributively stores the operated hash value in a plurality of second terminal devices (e.g., the second terminal devices 120 and 130). In the case where the user of the first terminal device (for example, the terminal device 110) suspects that the acquired data distributively stored in the plurality of second terminal devices (for example, the second terminal devices 120 and 130) is tampered with by another person, the acquired data may be subjected to a hash operation, so that the hash value obtained by the operation is compared with the hash value distributively stored in the plurality of second terminal devices (for example, the second terminal devices 120 and 130) in advance, and it is determined whether the acquired data is tampered with by another person.
Optionally, the method further comprises: the block chain server determines a processing instruction for data uploading; the block chain server determines the position information of the data storage position; the block chain server generates an address related to the encrypted data according to the processing instruction and the position information; and the blockchain server stores the address in at least one block of the blockchain.
Specifically, the blockchain server 200 designs the address related to the encrypted data in segments, where each segment represents a different function. One of the sections is a processing instruction for uploading data, and the other section represents position information of a position where the data is stored (wherein a time stamp is automatically recorded). Therefore, the blockchain server 200 first determines the processing instruction for uploading data and the location information of the location where the data is stored. The blockchain server 200 then generates an address associated with the encrypted data based on the processing instruction and the location information. The last block chain server 200 stores the address in at least one block of the block chain. Thus, in this way, the attribution of the distributed stored data may be determined. For example, in the case where the distributed stored data is video information, the video copyright attribution is allowed to be determined.
Optionally, the data is movie information, and the method further comprises: the method comprises the steps that a block chain server receives an acquisition request for acquiring movie and television information sent by first terminal equipment; the block chain server responds to the acquisition request and acquires the video information from the plurality of second terminal devices; and the block chain server sends the movie and television information to the first terminal equipment.
Specifically, the first terminal device 110 may directly communicate with a plurality of second terminal devices (e.g., the second terminal devices 120 and 130) by multiplexing cell resources (D2D protocol), thereby rapidly and efficiently acquiring data. Similarly, the first terminal device 110 may request the blockchain server 200 to acquire data pre-stored in a plurality of second terminal devices (e.g., the second terminal devices 120 and 130). The pre-stored data may be video information. At this time, the blockchain server 200 receives the acquisition request for acquiring the movie information transmitted by the first terminal device 110. Then, the blockchain server 200 acquires the movie information from the plurality of second terminal devices (for example, the second terminal devices 120 and 130) in response to the acquisition request. And the blockchain server 200 sends the movie information to the first terminal device 110. Thus, in this way, the first terminal device 110 can also acquire data, which is stored in a pre-distributed manner in a plurality of second terminal devices (e.g., the second terminal devices 120 and 130), from the blockchain server 200.
Optionally, the method further comprises: the method comprises the steps that a block chain server receives play notification information sent by a first terminal device, wherein the play notification information is used for indicating that a user of the first terminal device plays movie and television information; and the block chain server responds to the playing notification information and sends the preset digital certificate corresponding to the movie information to the account of the user.
Specifically, the blockchain server 200 receives the play notification information sent by the first terminal device 110. Wherein the playing notification information is used to indicate that the user of the first terminal device 110 has played the movie information. At this time, the blockchain server 200 transmits a preset digital pass-through corresponding to the movie information to the account of the user in response to the play notification information. Wherein the digital certificate may be embodied in the form of an integral, for example, but not limited to. Thus, in this way, the user's enthusiasm for watching video can be fully mobilized.
Further, according to a second aspect of the present embodiment, a block chain based data acquisition method is provided, which is implemented by the first terminal device 110 shown in fig. 2. Fig. 4 shows a flow diagram of the method, which, with reference to fig. 4, comprises:
s402: a first terminal device receives an acquisition instruction for acquiring data input by a user, wherein the data are stored in a plurality of second terminal devices in a distributed manner through a block chain server in advance, and the first terminal device and the second terminal devices are nodes in a block chain; and
s404: and the first terminal equipment responds to the acquisition instruction, directly communicates with the plurality of second terminal equipment through multiplexing the cell resources respectively, and acquires data.
Specifically, the first terminal device 110 receives an acquisition instruction for acquiring data input by the user. Wherein the data is distributed and stored in a plurality of second terminal devices (for example, the second terminal devices 120 and 130) through the blockchain server 200 in advance. Where the first terminal device 110 and the second terminal devices 120 and 130 are both nodes in a blockchain. Then, in response to the acquisition instruction, the first terminal device 110 directly communicates with a plurality of second terminal devices (for example, the second terminal devices 120 and 130) by multiplexing cell resources (D2D protocols), respectively, so as to acquire data distributively stored in the second terminal devices 120 and 130 in advance.
Thus, in this way, terminal devices configured with D2D protocols are added to the blockchain, such that each terminal device becomes a node of the blockchain. In the case where the first terminal device 110 wants to acquire data, it is possible to quickly and efficiently acquire data distributively stored on a plurality of second terminal devices (e.g., the second terminal devices 120 and 130) by directly performing communication by multiplexing cell resources (D2D protocol). Therefore, the problem that a distributed storage method capable of combining a D2D technology and a block chain technology for data is lacked in the prior art is solved.
Optionally, the method further comprises: the first terminal equipment detects whether the acquired data contains video information or not; and the first terminal equipment embeds a video player in the movie information under the condition that the detection data contains the movie information, so that a user can play the movie information through the video player.
Specifically, the first terminal device 110 detects whether the acquired data contains movie information. And the first terminal device 110 embeds the video player in the movie information in the case that the detection data contains the movie information, so that the user can play the movie information through the video player. Therefore, the first terminal device 110 has a D2D movie playing function, and the experience effect of the user is improved.
Further, a Network cloud data Storage server NAS (Network Attached Storage) can reduce the burden of a cloud server to which the Network cloud data Storage server NAS (Network Attached Storage) belongs through participation of a client. On the other hand, the NAS server, as a super node in the P2P network, may also provide closer (logical/physical) network resources for the P2P network. At the same time, the NAS server node can also provide and supplement other required resources that it lacks for the P2P network. The method for obtaining the resources nearby ensures the speed of obtaining the resources, thereby improving the performance and the speed of the whole system. Moreover, the management of the nodes is proved through the workload of the block chain, and the added nodes obtain the operation income, so that the transaction is more transparent and fair. The integration of block chain payment enables global payment and global nodes to become possible, the participation of the whole people is easier, and computing resources are more fully utilized. It can be applied in two ways:
1) Digital file authentication: the method comprises the steps that a user spontaneously generates content in an ecology, a 5G technology is applied to achieve one-key distribution to all internet mainstream social platforms, and after a time stamp is added to a block chain, the distributed content automatically achieves self-authentication and generates a digital certificate. The file is sent to all computers around the world in a scattered manner after being encrypted by the block chain hash value, and the target client performs D2D accurate extraction by using an encrypted private key corresponding to a public key of a distributed computer. In other words, this is a content encryption protocol, which hides the file content such as pictures in digital information by continuous transformation that cannot be perceived by vision, so as to achieve the effects of copyright protection and the like.
2) Video file right, movie & TV broadcast, video upload and live broadcast function: the video information address is designed in a segmented mode, wherein each segment represents different functions, and one segment is a processing code number for uploading the video; the other segment represents the deposit location (where the timestamp has been automatically recorded). In this way, video copyright attribution may be determined.
The 5G technology provided in this embodiment is combined with a block chain decentralized data storage file system, and is combined with a 5G technology to perform fast D2D arrangement, so that after an oversized file is uploaded quickly, the oversized file is distributed in each node in a dispersed manner by using the block chain technology, and a D2D movie playing function is provided at the same time. By the application of the dual-system design, LIUNX and Android are fused together, and a network cloud data storage server (NAS) has both film and television and software digital evidence (integral function). Here, we introduce the following D2D technologies, such as mobile phones or computer devices (LINUX for example), where data packets are to be transmitted through a base station, and the delay is high and the efficiency is low; in the 5G era, data can be directly transmitted between mobile phones, and only one contact is needed for a base station, so that the efficiency is greatly improved, and the possibility that the devices are dispersedly distributed and share a client database is provided for people. Moreover, after the PDFT algorithm is added and the hash processing is performed, all devices are uplinked, which is the true blockchain mobile phone or NAS. The user spontaneously generates content in the ecology, the content is distributed to each internet mainstream social platform in a one-key mode through the 5G technology, the distributed content automatically achieves self-authentication and generates a digital certificate after a block chain is added with a timestamp. The file is sent to all computers around the world in a scattered manner after being encrypted by the block chain hash value, and the target client performs D2D accurate extraction by using an encrypted private key corresponding to a public key of a distributed computer. In other words, this is a content encryption protocol, and the content of a file such as a picture is hidden in digital information through continuous transformation which cannot be perceived by vision, so as to achieve the effects of copyright protection and the like.
Furthermore, the system is added with the functions of movie playing, video uploading and live broadcasting, and digital certificates (scores) can be obtained while movie files are played and uploaded.
