[0035] Figure 1 An application scenario diagram of the electronic file management method, apparatus, device, medium, and program product according to an embodiment of the present disclosure is schematically shown.

[0041] It should be understood that Figure 1 The number of terminal devices, networks, and servers in the above description is only illustrative. According to the needs of implementation, there can be any number of terminal devices, networks, and servers.

[0042] The electronic archive management method according to the embodiments of the present disclosure will be described in detail below based on the scenarios described above. Figure 1 Figures 2-8 The electronic archive management method according to the embodiments of the present disclosure will be described in detail below based on the scenarios described above.

[0043] Figure 2 A flowchart of an electronic archive management method according to an embodiment of the present disclosure is schematically shown.​

[0044] As Figure 2 shown, the electronic archive management method of this embodiment includes operation S210~operation S270.

[0045] In operation S210, a system account is established in the blockchain, and the system account corresponds to a business system.

[0046] According to embodiments of the present disclosure, electronic archive management includes operations such as uploading, modifying, tracing, and verifying electronic archives. A business system will generate business data when handling business. In order to facilitate the organization and summary of business data, the end-of-day business data can be archived to the archive system to form electronic archives.

[0047] It can be understood that the business system can be multiple business systems, and each business system can handle the same business or different business. For each business system, a system account is generated on the blockchain for uploading the business data generated by the business system.

[0048] In operation S220, an electronic archive is generated according to the business data of the business system, and the electronic archive includes an initial archive and a modified archive.

[0049] Figure 3 A method flowchart for generating an electronic archive according to an embodiment of the present disclosure is schematically shown.

[0050] According to embodiments of the present disclosure, as Figure 3 shown, the electronic archive is generated, for example, by steps S321~S324.

[0051] S321, initial business data is obtained from the business system.

[0052] According to embodiments of the present disclosure, the electronic archive includes, for example, an initial archive and a modified archive. The initial business data is, for example, the end-of-day business data archived to the archive system.

[0053] S322, an initial archive is generated according to the initial business data.

[0054] According to embodiments of the present disclosure, the initial archive is assembled in a first json format for uploading.

[0055] For example, the first json format includes an archive ID, a file, an operation, and an archive attribute. The archive ID is the ID of the entire initial archive, which is the unique identification of the archive. The file is a plurality of files contained in the archive, for example, recorded as a plurality of file IDs. The operation is an operation performed by an operator on the archive, for example, recorded as an operator and an operation name, and the operation includes, for example, approval, review, etc. The archive attribute is a feature of the archive itself, for example, an archive name, a creation time, etc.

[0056] S323, modifying the initial business data and / or recording the operation performed on the initial business data to obtain a modification item.

[0057] According to an embodiment of the present disclosure, based on actual needs, the initial business data needs to be modified, such as adding files, deleting files, updating operations, etc. The operation performed on the initial business data includes, for example, approval, etc. The type and content of the modification are recorded to obtain a modification item.

[0058] S324, generating a modification file according to the modification item.

[0059] According to an embodiment of the present disclosure, the modification file is assembled on the chain in a second json format, for example.

[0060] For example, the second json format includes a file ID, an added file, a deleted file, an operation change, and an attribute change. The file ID is the ID of the initial file described above, which is used to ensure the traceability of all operations on the initial file. The added file is the ID of the added file recorded. The deleted file is the ID of the deleted file recorded. The operation change is the operation name and operator of the changed operation recorded. The attribute change is the change of the characteristics of the file itself. By generating the modification file, the modification content can be recorded when the file is modified, and the modification content is independently chained, solving the problem that the chained content cannot be modified. At the same time, since the modification file and the initial file have the same file ID, even if the modification file and the initial file are chained at different times and are chained to different blocks, the complete file can be traced.

[0061] In operation S230, an account of the electronic file is established.

[0062] According to an embodiment of the present disclosure, in order to facilitate the contact between accounts, in addition to establishing a system account for a business system, a file account needs to be established for each file, which is used for transfer transactions with the system account on the blockchain.

[0063] For example, for each file, a hash value is calculated according to the file id and the current timestamp, which is used as the key of the file and as the account password of the file account. From the file level, it is ensured that the file cannot be illegally modified, and the data security is improved.

[0064] In operation S240, the electronic file is signed using the key of the system account to obtain a signed file, and the signed file includes a signed initial file and a signed modification file.

[0065] According to an embodiment of the present disclosure, the key of the system account includes a public key and a private key, for example. The electronic file can be signed by using the private key of the system account, for example. And the signed file is verified by using the public key of the system account after being uploaded to the blockchain.

[0066] In operation S250, the signed initial file and the signed modified file are uploaded to the blockchain respectively through a transfer transaction between the system account and the file account.

[0067] For example, the electronic file is uploaded to the blockchain as the content of the transfer transaction by the system account transferring a certain amount of money to the corresponding file account.

[0068] Figure 4 A method flowchart of uploading the signed file to the blockchain according to an embodiment of the present disclosure is shown schematically.

[0069] According to an embodiment of the present disclosure, as shown in Figure 4 the signed file is uploaded to the blockchain, for example, through steps S451-S452.

[0070] S451, the signed initial file is uploaded to the blockchain in a first json format.

[0071] S452, the signed modified file is uploaded to the blockchain in a second json format.

[0072] For example, the same file with the same ID can contain different contents at different times, that is, the content of the file can change over time, so the same ID file containing different contents needs to be uploaded separately at different times. The file with different contents is uploaded in different data structures, which is flexible and convenient for the whole life cycle management of the electronic file.

[0073] In operation S260, the hash value of the signed file is calculated.

[0074] Figure 5 A method flowchart of calculating the hash value according to an embodiment of the present disclosure is shown schematically.

[0075] According to an embodiment of the present disclosure, as shown in Figure 5 the hash value of the signed file is calculated, for example, through steps S561-S562.

[0076] S561, the initial hash value of the signed file is calculated by using a hash algorithm.

[0077] For example, the hash value of the signed file (signedData) is calculated, denoted as cunHash of the file. The hash algorithm can be SHA256, SHA3, etc.

[0078] S562, selecting at least two characters from the initial hash value, and exchanging the positions of the at least two characters to obtain the hash value of the signature file.

[0079] For example, the calculated initial hash value has 64 characters. It can be agreed that the first character and the last character are transposed, or the second character and the last character are transposed to obtain the twice-encrypted hash value.

[0080] It can be understood that the number of transposed characters is not limited to two, but can be more. The positions of the characters are not limited to the first, second and last characters, but can be characters at any position. By transposing the characters at any number and at any position of the initial hash value, the signature file is twice encrypted, and the probability of key cracking is reduced.

[0081] In operation S270, the signature initial file and the signature modified file are traced on the blockchain through the hash value of the signature file.

[0082] Figure 6 A method flowchart of tracing an electronic file according to an embodiment of the present disclosure is schematically shown.

[0083] According to an embodiment of the present disclosure, as Figure 6 shown, for example, the electronic file is traced through steps S671-S672.

[0084] S671, determining the first json format initial file and the second json format modified file according to the hash value of the signature file.

[0085] S672, merging the first json format initial file and the second json format modified file to obtain the traced electronic file.

[0086] For example, the hash value of the signature file has file ID information, which can be indexed to the respectively chained initial file (file initial record) and modified file (all change records) on the blockchain. The indexed initial file and modified file are assembled according to certain logic, for example, in chronological order, operation type, operator, etc., to obtain a complete electronic file, i.e., the tracing of the electronic file is completed.

[0087] In order to improve the tracing efficiency, an index ID can be established, and the index ID is mapped to the block corresponding to the transfer transaction.

[0088] Figure 7 A method flowchart of tracing an electronic file according to an embodiment of the present disclosure is schematically shown.

[0089] According to an embodiment of the present disclosure, as Figure 7As shown, the electronic file is traced, for example, through steps S771-S774.

[0090] S771, generating an index ID according to the hash value of the signature file.

[0091] For example, the cunHash of the file can be further processed, for example, by adding the file ID, and the extraId (i.e., the index ID) of the transaction object can be obtained, which is used to trace the electronic file on the blockchain.

[0092] S772, uploading the index ID to the blockchain.

[0093] For example, when the system account and the file account establish a transfer transaction, the index ID is also uploaded to the chain. The mapping relationship between the index ID and the block corresponding to the transaction is established on the chain, which can speed up the retrieval speed of the signature file through the index ID.

[0094] S773, establishing a mapping relationship between the index ID and the block of the transfer transaction.

[0095] S774, tracing the electronic file according to the index ID after the mapping relationship is established.

[0096] It can be understood that in addition to establishing the mapping relationship on the blockchain, the file ID, cunHash and signature file can also be saved in the local relational database to form a one-to-one mapping relationship, which is convenient for subsequent tracing.

[0097] In operation S280, the full-life-cycle electronic file is obtained according to the traced signature initial file and the signature modified file.

[0098] According to an embodiment of the present disclosure, the full-life-cycle electronic file is, for example, the latest complete electronic file obtained by arranging all initial files and modified files obtained by the same file ID up to the current time node. It is equivalent to an electronic file that contains all modifications to the initial business data and records all operations performed on the initial business data. By tracing the full-life-cycle electronic file, all data related to the electronic file can be intuitively displayed in one electronic file, which has high application value.

[0099] According to an embodiment of the present disclosure, the electronic file management method further comprises verifying the signature file.

[0100] Figure 8 The method flowchart of verifying the electronic file according to an embodiment of the present disclosure is schematically shown.

[0101] According to an embodiment of the present disclosure, as shown in Figure 8 For example, the signature electronic file is verified, for example, through steps S881-S886.

[0102] S881, obtaining the file ID of the electronic file.

[0103] S882, determining the hash value of the signed file before uploading to the blockchain according to the file ID.

[0104] S883, determining the hash value of the signed file on the blockchain.

[0105] For example, the signed file on the blockchain is a signed file obtained by multiple times of uploading, wherein most of the signed files are modified files obtained by modifying the initial file. Therefore, it is necessary to determine whether the modification of the initial file is a legal modification.

[0106] S884, comparing the hash value of the signed file before uploading to the blockchain with the hash value of the signed file on the blockchain.

[0107] For example, the hash value of the off-chain signed file is determined by the file ID, and is compared with the hash value of the on-chain signed file. If the hash values are consistent, it is a legal modification.

[0108] S885, verifying the signature of the signed file by the key of the system account.

[0109] For example, the signed file on the chain is determined by the file ID, and the signature of the signed file is verified by the public key of the system account. If the verification is successful, the signed file is a legal uploading.

[0110] S886, determining that the electronic file verification is successful when the hash value of the signed file before uploading to the blockchain is consistent with the hash value of the signed file on the blockchain, and the verification of the signed file is successful. By comparing the hash value of the signed file and verifying the signature of the signed file, the authenticity of the source of the signed file is ensured.

[0111] Optionally, in order to improve the efficiency of the verification of the signed file, the electronic file can be verified by deploying a smart contract.

[0112] Based on the above electronic file management method, the present disclosure further provides an electronic file management device. The following will be combined with the Figure 9 The device will be described in detail.
