Abstract
The invention discloses a user comment anti-tampering system based on a block chain, which at least comprises a user side, a server side and a block chain end, wherein the user side is used for initiating comments; the server is used for receiving and storing the comments and transmitting the comments to the block chain end; the blockchain end is used for receiving, storing and broadcasting comments to users. The invention has the beneficial effects that: the comment data of the user are encrypted through multi-party consensus and the time stamp of the block chain, so that the user data acquired by the server are stored on the chain, and the data are prevented from being deleted and modified maliciously by some people. The data seen by the user is guaranteed to be real and effective. Thereby enabling the user to more objectively understand the reputation level of the viewed merchant store. It is also a more stringent constraint on merchants to forego the desire to remove user perks through monetary purchases, prompting them to increase their own service levels.
Description
Technical Field
The invention relates to the technical field of information, in particular to a user comment anti-tampering system and a user comment anti-tampering method based on a block chain.
Background
The blockchain technology is a technical scheme for decentralized and collective maintenance of a distributed account book, and is essentially a distributed database system with a plurality of nodes participating together, the blockchain is not a single technology, but a result of multi-technology integration, a reliable and difficult-to-tamper account book record is maintained by using the blockchain, trust risk can be reduced, and maintenance cost of many participants is effectively reduced. When the data is stored through the block chain, the consensus among multiple parties is required to be obtained, and the data cannot be falsified or forged after the data is chained.
Because the data of the enterprise application is distributed on a few back-end servers in a centralized way, the data is concentrated in a few hands, and individual developers have all operation rights on the data, so that some people obtain illegal benefits by abusing own rights, such as charging and deleting bad comments of users on merchants.
Disclosure of Invention
In view of the defects of the prior art, the invention provides a user comment anti-tampering system based on a blockchain and a method thereof, and aims to store comments of users through a blockchain technology and prevent all comment data from being maliciously tampered by some people. Thereby ensuring the true validity of the data.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a user comment anti-tampering system based on a blockchain at least comprises a user side, a server side and a blockchain end, wherein the user side, the server side and the blockchain end are connected with one another through a network
The user side is used for initiating comments;
the server is used for receiving and storing the comments and transmitting the comments to the block chain end;
the blockchain end is used for receiving, storing and broadcasting comments to users.
It should be noted that, when a comment needs to be called, the server obtains the comment from the block link end, and then displays the comment to the user through the server.
The method of the invention is realized by the following steps:
a method of user comment tamper-proofing based on blockchains, the method comprising:
s1, constructing a block chain network for storing comment information;
s2, obtaining comment data of the user;
s3, encrypting the comment data of the user and acquiring a Hash value;
s4, storing the encrypted data and the hash value on the block chain network module through an intelligent contract and an SDK interface;
s5 storing the blockchain by means of consensus verification and synchronous user data;
and S6, decrypting, verifying and displaying the user data on the block chain.
The invention has the beneficial effects that:
the comment data of the user are encrypted through multi-party consensus and the time stamp of the block chain, so that the user data acquired by the server are stored on the chain, and the data are prevented from being deleted and modified maliciously by some people. The data seen by the user is guaranteed to be real and effective. Thereby enabling the user to more objectively understand the reputation level of the viewed merchant store. It is also a more stringent constraint on merchants to forego the desire to remove user perks through monetary purchases, prompting them to increase their own service levels.

Detailed Description
The present invention will be further described below, it should be noted that the present embodiment is based on the technical solution, and a detailed implementation manner and a specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
As shown in FIG. 1, the present invention is a block chain-based system for preventing user comment from being tampered, which at least comprises a user end, a service end and a block chain end, wherein
The user side is used for initiating comments;
the server is used for receiving and storing the comments and transmitting the comments to the block chain end;
the blockchain end is used for receiving, storing and broadcasting comments to users.
It should be noted that, when a comment needs to be called, the server obtains the comment from the block link end, and then displays the comment to the user through the server.
As shown in fig. 2, the method of the present invention is implemented by:
a method of user comment tamper-proofing based on blockchains, the method comprising:
s1, constructing a block chain network for storing comment information;
s2, obtaining comment data of the user;
s3, encrypting the comment data of the user and acquiring a Hash value;
s4, storing the encrypted data and the hash value on the block chain network module through an intelligent contract and an SDK interface;
s5 storing the blockchain by means of consensus verification and synchronous user data;
and S6, decrypting, verifying and displaying the user data on the block chain.
Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
