In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention discloses an electronic file management method based on a block chain, which is applied to a block chain network, wherein the block chain network comprises an audit terminal and a plurality of electronic file manufacturing terminals, and each electronic file manufacturing terminal is used as a node in the block chain network to upload an electronic file to the block chain network; as shown in fig. 1, the method comprises the steps of:
for example, the electronic file making terminal can perform a primary review and a secondary review on the electronic file before the uplink of the electronic file according to the actual file management requirement to ensure the accuracy of the information contained in the electronic file stored in the uplink. Different electronic file chaining modes may exist, a user can compile a corresponding intelligent contract at an electronic file making terminal according to preset rules to complete subsequent electronic file chaining processing, and the compiled electronic file intelligent contract can include but is not limited to an electronic file identifier generation intelligent contract. The written intelligent contracts can be directly configured in the blockchain network or configured in a side chain which is in communication connection with the blockchain network, and when the electronic file uploaded from the electronic file making terminal is received, the electronic file identification is triggered to be executed to generate the intelligent contracts and generate the electronic file identification.
102, sending the electronic file to an auditing terminal for auditing, so that the auditing terminal performs consistent hash operation on the electronic file and performs signature when the auditing terminal passes the auditing;
for example, the auditing manner of the electronic file by the auditing terminal may be that when the auditing terminal receives the electronic file to be audited, a pre-configured intelligent contract for auditing the electronic file is obtained from the block chain network, and the received electronic file is audited according to the intelligent auditing manner of the electronic file, where the specific auditing content includes, but is not limited to, an electronic file format, validity of the content included in the electronic file, and the like. For example, the format comparison file corresponding to the type can be obtained from a pre-configured type library according to the type of the obtained electronic file in the checking mode of the format of the electronic file, the obtained format of the electronic file to be checked is compared with the format comparison file through an intelligent contract, and the electronic file to be checked passes the checking mode when the comparison result is consistent. And after the verification is passed, the verification terminal can call a pre-configured intelligent contract to carry out consistent hash operation on the electronic document and sign the electronic document.
And 103, when the audit result meets the uplink requirement, packaging and uplink storing the electronic file, the electronic file identifier corresponding to the electronic file and the hash value.
Illustratively, according to the rule in the intelligent contract and the consensus mechanism of the block chain, the information related to the electronic file is uplink stored, and the combination of the electronic file and the block chain is completed. If the electronic archive information changes, the above step 101 and step 103 may be repeated to add the electronic archive information stored in the block chain network, so as to form the electronic archive and audit tracing. Meanwhile, according to different types of the electronic file making terminals, corresponding authorities can be allocated to the corresponding electronic file making terminals in advance, the electronic file making terminal with the larger authority can be used as a user node, an endorsement node and a packaging node to assist in completing data chaining operation, and the electronic file making terminal with the smaller authority can be used as the user node only for uploading data to the blockchain network.
According to the block chain-based electronic file management method, the electronic file is stored in the block chain by combining the block chain technology, the uplink data of the electronic file system can be persistently stored according to the decentralized and distrust of the block chain technology, and the electronic document is prevented from being illegally tampered or maliciously damaged according to the technical characteristics of the block chain technology, such as non-tampering and non-counterfeiting, so that the safety of the stored electronic document is ensured.
As an optional embodiment of the present invention, before step 101, the method further comprises: when an electronic file uplink request sent by any electronic file making terminal is received, checking the user identity corresponding to the electronic file making terminal, and determining whether the user finishes registering in a block chain network; if not, triggering and executing the intelligent contract to complete the registration operation of the user; and adding the block chain account obtained by registration into an account management intelligent contract for account management.
For example, the determination method of whether the user identity is registered may be that when the user identity information uploaded from the user information input module of the electronic file making terminal is received, a pre-configured identity verification intelligent contract is triggered to run, the newly uploaded user identity information is matched with the identity information historically stored on the block chain network through the identity verification intelligent contract, when the same identity information is not matched, the registration intelligent contract is triggered to execute the registration intelligent contract to complete the registration operation for the user, and the block chain account obtained by registration is added to the account management intelligent contract for account management. In order to facilitate the examination and unified management, the ID of the electronic file in the blockchain network can be set to the ID of the electronic file in the original electronic file system, and then the association between the electronic file system and the blockchain system is completed.
As an optional embodiment of the present invention, the method further comprises: acquiring user account information of the uploaded electronic file; when the audit of the audit terminal passes, acquiring audit staff information from the audit terminal; and linking and storing the user account information and the auditor information. By storing the user account information of the uploaded electronic file and the corresponding audit staff information in the block chain, the electronic file can be traced according to the stored user account information and the corresponding audit staff when the stored electronic file is abnormal.
As an optional embodiment of the present invention, the method further comprises: when an electronic file information query request uploaded by any user node is received, acquiring electronic file information from a block chain network according to electronic file identification information in the electronic file information query request; and sending the acquired electronic file and the corresponding hash value to the user node, so that the user node verifies the acquired electronic file by using the hash value in the acquired electronic file information.
Illustratively, since the electronic file information stored in the blockchain network includes the electronic file identifier, the user can obtain the electronic file information corresponding to the identifier from the blockchain network through the electronic file identifier obtained in advance, perform a secondary hash operation on the obtained electronic file data, compare the operation result with the hash value obtained from the blockchain, and when the comparison result is consistent, indicate the authenticity of the electronic file data obtained from the blockchain.
