Embodiment 1

[0047] The present invention includes user office equipment, block chain system, etc., wherein said user office office equipment is the software and hardware used by the user to operate the office document; the block chain system is loaded into the office office equipment as a plug-in, using its It is safe and reliable, cannot be tampered with, supports post-event auditing and traceability, and realizes the safety and reliability of office documents.

[0048] Through multiple nodes in the blockchain system to jointly manage a certain office equipment, the distributed storage and management of office document data is realized. When a certain office device generates new network behaviors, such as the user creates a new document, the user modifies the document, the user queries the data of the document, etc., the office device will store the user access information (such as the visitor's hard disk serial number, Visitor's access time, etc.) and office document information (such a...

Embodiment 2

[0051] The present invention provides a block chain system to achieve the goals of security and credibility of office documents, prevention of illegal tampering of content, and traceability of historical data. The blockchain system is loaded into the office equipment as a plug-in to monitor changes in the status of office documents in real time. The implementation process is as follows:

[0052] The blockchain system includes at least one first node, which is used to connect with office equipment and receive data from office equipment in real time. Each first node is connected to at least one office device, each office device is connected to multiple first nodes, and the number of connected first nodes is not less than two, so that if a node fails, the Corresponding operations can be performed by connecting other nodes, thereby ensuring data security. Among all the first nodes that manage a certain office equipment, the closest one can be used as the target first node. When t...

Embodiment 3

[0066] The blockchain-based office document credibility verification method uses the blockchain smart contract to realize real-time storage of office documents. Users participating in the blockchain system first jointly formulate the conditions for the automatic execution of the contract, including the conditions for creating and saving office documents, and the conditions for accessing office documents; after the participating users formulate the conditions, deploy the contract to the blockchain system , the corresponding blockchain node executes the smart contract. For the conditions of creating and saving the document, if the user clicks the save button of the office document, the system will actively submit the document record to the smart contract, and the stored content is the document information, user information and location information. After the smart contract detects the storage request, it automatically executes, creates a block for the operation within a period o...

Abstract

The invention discloses an office document credibility verification method based on a block chain, and the method achieves the real-time storage of office documents through an intelligent contract ofthe block chain. Firstly, users jointly formulate automatic contract execution conditions; and after the participation user formulates the condition, the contract is deployed into the block chain system, and the intelligent contract is executed by the corresponding block chain node. For the conditions of document establishment and storage, if a user starts a storage operation, the system can actively submit a document record to an intelligent contract, and the stored content is document information, user information, position information and the like. The intelligent contract is automaticallyexecuted after detecting the storage request, a block is created for the operation within a period of time, and a hash value generated by the record is transmitted to the block chain system. For document access conditions, a contract can formulate document information which can be obtained by a user in advance, and a block chain system can output data information according to triggering conditionsof the intelligent contract to complete permission access of the user to a certain office document.

Description

technical field [0001] The present invention relates to the technical field of block chain, and more specifically relates to a method and system for verifying the credibility of office documents based on block chain. Background technique [0002] At present, office software is widely used in enterprises, schools, hospitals, etc., and office documents are of great significance to users' study, work, and life. Users use office documents to record a series of information and perform operations such as modification, query, encryption, and deletion. If documents are lost or content is illegally tampered with, it will bring serious losses to users. [0003] A blockchain is a sequence of blocks that holds a complete list of transactions. A block is a carrier for storing transaction summary information, and it is also a structural unit of data storage in the blockchain. The block body consists of transaction counters and transactions, which are mainly used to store transaction sum...
