Referring to FIG. 1, the present invention provides a block chain-based video management method (hereinafter referred to as the management method), and the management method includes:

Step S100, obtaining storage space after performing virtualized network binding processing on the storage resources of the network camera unit.

Specifically, upload the local storage resources of the network camera unit, serialize the video recording resources, and perform virtualization processing on the storage resources of the network camera unit, and further bind the virtualized storage resources and network resources. , and then form a decentralized storage space.

In this step, by virtualizing the storage resources into a storage pool, the scattered storage resources are further integrated, so that the storage resources of the network camera unit have the ability to divide and redistribute resources, and at the same time combine with network resources, further Integrate each storage subsystem on the storage network into one or more storage pools that can be centrally managed, and create one or more different required volumes in the storage pool as required, and store these required volumes according to a certain read volume. The write authorization is allocated to various servers on the storage network, thereby enabling efficient utilization of storage resource capacity and centralized management of stored data.

In this step, the storage resource is serialized, converted into a form that can be stored and transmitted, and the storage resource is processed into persistent storage data, which can be further read from the persistent storage data.

In this step, the storage resources of the network camera unit are virtualized at the same time, which can meet the performance and capacity requirements of the network camera unit to store data with the highest efficiency and the lowest cost. It plays a very significant role in improving functional requirements such as backup, recovery, and archiving. It not only greatly saves management time and money, but also storage virtualization can effectively improve the overall performance and availability of the storage environment.

To explain, serialization enables other code to view or modify object instance data that would otherwise be inaccessible without serialization. To be precise, code execution serialization requires a special permission, which is not granted under the default policy for code downloaded over the Internet or for Internet code; only code on the local computer is granted this permission, thus effectively guaranteeing webcam unit security.

Step S200 , record data in the storage space by means of a distributed blockchain ledger.

Specifically, the distributed blockchain ledger is used to record data in the storage space. The advantage of blockchain technology is decentralization, so that the storage space forms a decentralized database, in which point-to-point data transmission can be realized. , Distributed blockchain technology is applied to the storage management of network camera units, which can turn storage resources into a decentralized storage space, and at the same time realize that all participating users in the network can perform data storage and other actions in this storage space. At the same time, the data storage action status is recorded, which effectively avoids the possibility of video data being tampered with at the technical level, and greatly ensures the security of the data stored in the network camera unit.

Preferably, a distributed blockchain ledger method is used to record the space data of the storage space, the duration of use data and the number of accesses, so as to obtain the use status and access status of the network camera unit from the server in real time. , effectively improve the management effect of the network camera unit.

Step S300: Encrypt the storage data of the network camera unit, and transmit the encrypted storage data to the storage space.

In this step, the stored data of the network camera unit is encrypted and then sent to the storage space. In this solution, a symmetric encryption algorithm or asymmetric encryption algorithm is used, and a one-machine-one-household method is used to encrypt the target data. The stored data of the network camera unit is effectively protected.

Among the above-mentioned encryption symmetric algorithms, including DES, a data encryption standard, which is fast and effective for encrypting large data; 3DES is based on DES, which uses three different keys to encrypt a piece of data three times, thereby effectively improving the The strength of data encryption; AES, Advanced Encryption Standard, is a new generation of encryption algorithm standard, which has high speed and higher security level.

Among the above-mentioned asymmetric encryption algorithms, including RSA, which is a public key algorithm that supports variable-length keys; ECC, elliptic curve cipher coding; ECC, compared with RSA, has strong anti-attack, less computation and processing speed faster, etc.

In the solution of the present invention, any one or more encryption algorithms mentioned above are used to encrypt the stored data of the network camera unit.

Preferably, the AES algorithm is used to encrypt the stored data of the network camera unit, thereby effectively improving the security of the stored data.

In the above steps, the combination of blockchain technology and AES data encryption technology can effectively solve the problems of storage resource virtualization and storage data security. At the same time, virtual serialization of storage resources can make users' idle resources more reasonable, Safe use.

In this step, preferably a peer-to-peer network is used to transmit the encrypted storage data to the storage space, thereby enabling information exchange and sharing, computing resources, storage resources, and network resource sharing of the network camera unit.

It needs to be explained that a peer-to-peer network refers to a peer-to-peer computer network, a distributed application architecture that distributes tasks and workloads among peers, and is a peer-to-peer computing model formed at the application layer. A network or network form.

Step S400, obtaining the data storage route of the target network camera unit in the storage space by means of a distributed blockchain ledger.

Specifically, the storage route of the data stored in the storage space can be retrieved through the distributed blockchain ledger method, so that the data storage route of the target network camera unit can be obtained point-to-point, and then the data storage route can be obtained in the decentralized storage space. Find the storage route of the target storage data more accurately.

Step S500: Obtain the decryption verification of the user, and interpret the stored data of the target network camera unit after passing the decryption verification.

After retrieving the storage route of the stored data, the user's decryption verification is performed. After the decryption verification is passed, the stored data in the storage space can be interpreted, and the stored video of the target network camera unit can be obtained in the storage space.

Referring to FIG. 2, on the basis of the above solution, step 100 includes:

Step 110: Obtain user authorization, perform serialization processing on the network camera unit, and perform virtualization processing on the local storage resources of the network camera unit.

Specifically, after obtaining the authorization of the user, the network camera unit is serialized, and then the video data of the network camera unit is converted into storage data that can be stored and transmitted.

To explain, all fields of an object instance are serialized, which means that the data is represented as the instance's serialized data. This makes it possible for code capable of interpreting the format to determine the value of this data independent of the accessibility of the member.

Step 120: Obtain the storage space after binding the virtualized storage resource and the network resource.

After virtualizing the storage resources, a public storage pool is formed, and the storage pool is further bound to the network resources, so as to form a network-shared storage pool on the network, which can improve the storage capacity of each network camera unit. Data management efficiency.

It should be explained that the most common understanding of storage virtualization is the abstract representation of storage hardware resources. By integrating one (or more) target service or function with other additional functions, a useful comprehensive function service is provided uniformly. Typical virtualization includes the following situations: shielding the complexity of the system, adding or integrating new functions, simulating, integrating or decomposing existing service functions, etc. Virtualization acts on one or more entities, and these entities are used to provide storage resources or services.
