Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, the plurality of data storage devices may be general computers or general mini servers, which are connected to each other. Since there are a plurality of data storage devices, there are also a plurality of connection methods. For example, all the data storage devices are placed together and connected to each other by a network cable, or a plurality of data storage devices are placed in different places and connected to each other by a network.

The data storage device is connected with the intelligent terminal device through the internet device, and the intelligent terminal device comprises electronic devices such as a mobile phone, a computer and a tablet personal computer.

How the intelligent terminal device uploads and downloads data information to and from the data storage device and how the data storage device stores data is described below with reference to the drawings.

Referring to fig. 2, the process of uploading data information to the data storage device by the intelligent terminal device is as follows.

Step 101, intelligent terminal equipment uploads data information to data storage equipment through internet equipment;

the data information referred to herein generally refers to information such as pictures, video, audio, and the like. In general, the intelligent terminal device is installed with client software, and a user can upload or download various data information to the data storage device through the client software. Of course, the user can also upload or download data information through the web page.

102, performing consensus verification on the data information by a consensus device;

103, encrypting the data information passing the consensus verification by an encryption device;

104, the storage device stores the encrypted data information on the data storage equipment;

and 105, the distribution device distributes the encrypted data information to other data storage equipment connected with the data storage equipment.

The data storage device comprises a consensus device, an encryption device, a storage device and a distribution device. The consensus device needs to perform consensus verification on the equipment uploaded by the intelligent terminal. The consensus verification is based on the requirement of a consensus mechanism, and the consensus mechanism is an algorithm for establishing trust and obtaining rights and interests among different nodes in a blockchain system.

After the consensus verification is completed, the encryption device encrypts the uploaded data information, and an encryption algorithm used in encryption is preset, so that the intelligent terminal device uploading the data information has a decryption algorithm corresponding to the encryption algorithm.

The storage device stores the encrypted data information. At the same time, the distribution means distributes the encrypted data information to other data storage devices connected thereto.

The process of downloading data information on the data storage device by the intelligent terminal device is shown in fig. 3.

Step 201, the intelligent terminal device sends a request for downloading data information to the data storage device through the internet device;

step 202, after receiving the application, the verifying device obtains the data information through other connected data storage devices, and compares the data information with the data information stored by the verifying device;

and 203, after the comparison result is consistent, the transmission device sends the data information to the intelligent terminal equipment through the internet equipment.

The data storage device comprises a verification device and a transmission device. After receiving a request for downloading data information sent by the intelligent terminal device, the data storage device can acquire data information on other data storage devices connected with the data storage device, wherein the data information is the data information requested to be downloaded by the intelligent terminal. Since the data storage device that first obtained the data information will distribute this data information to other data storage devices connected to it when uploading the data information (see step 105), the data information will be stored on all interconnected data storage devices. Therefore, the data storage system can take the data information stored in other data storage systems for comparison and verification, and the data information stored in the data storage system can be prevented from being tampered by others.

After the comparison result is consistent, it is proved that the data information is not tampered, and the data information can be sent to the intelligent terminal device, where the intelligent terminal device is the intelligent terminal device that sends the request for downloading the data information in step 201.

According to the above (page 3, lines 7-9 of the specification), the intelligent terminal device receives the encrypted data information, and the intelligent terminal device has a corresponding decryption algorithm, so that the intelligent terminal device can safely obtain the required data information.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
