Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a data management method, device and electronic equipment. Background Art

[0002] The traditional way to store electronic contract templates is to store them in a centralized database. However, the centralized database does not provide a version control function for the stored electronic contract templates, so that each time the electronic contract template is modified, the version before the modification will be overwritten, resulting in data loss of the version before the modification or confusion of the electronic contract template version, which makes the version control of the electronic contract template complicated and increases the difficulty of supervision and auditing. Summary of the invention

Even after the electronic contract template is modified, it can be rolled back to the previous version through the stored historical version number, thereby facilitating the control of the version of the electronic contract template, making version control simpler, while ensuring the traceability of the electronic contract template, reducing the difficulty of supervision and auditing, and facilitating audit tracing, so as to facilitate supervision and auditing of the entire process.

[0047] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0048] Traditional electronic contract templates are stored in a centralized database, which leads to difficulties in version control and supervision and auditing.

[0049] Therefore, the present application proposes a data management method, which saves the electronic contract template and the corresponding version number on the blockchain; when the electronic contract template is changed, the changed new electronic contract template and the corresponding version number are also saved on the blockchain, so that all versions of the electronic contract and the version number corresponding to each version are saved on the blockchain, so that the electronic contract template with the corresponding version number can be determined through the various version numbers of the electronic contract template. Even after the electronic contract template is modified, it can be rolled back to the previous version through the stored historical version number, thereby facilitating the control of the version of the electronic contract template, making version control simpler, and at the same time ensuring the traceability of the electronic contract template, facilitating audit tracing, so as to facilitate the supervision and audit of the entire process.

[0050] Reference Figure 1 The figure is a flow chart of a data management method provided by an embodiment of the present application, the method comprising:

[0051] S101, save the electronic contract template and the corresponding version number on the blockchain.

[0052] Among them, the structure definition of the electronic contract template can be as follows:

[0053] {

[0054] TemplateID / / Template identification code (English: Identity document, abbreviated as ID)

[0055] TemplateName / / Template name

[0056] TemplateFileHash / / Template file hash value (hash)

[0057] CreateTime / / Template creation time

[0058] Creator / / Template creator

[0059] TemplateType / / Template type

[0060] TemplateVersion / / Template version number

[0061] }

[0062] In an embodiment of the present application, the summary content of the electronic contract template may include template ID, template name, template file hash, template creation time, template creator, template type, and template version number.

[0063] Optionally, the electronic contract template and the corresponding version number can be saved on the blockchain by saving the summary content of the electronic contract template including the template ID, template name, template file hash, template creation time, template creator, template type, and template version to the blockchain, so as to ensure that the data of the electronic contract template is not tampered with during the off-chain exchange process, thereby ensuring the authenticity of the electronic contract template. In addition, only saving the above summary content of the electronic contract template to the blockchain can reduce the storage space occupied by invalid information, thereby reducing the waste of resources.

[0064] In the embodiment of the present application, the above template type is a public contract template or a private contract template. That is to say, the electronic contract template can be a public contract template or a private contract template.

[0065] The public contract template or private contract template can be obtained by adding supplementary terms to the built-in contract template (such as the general contract template) in the contract template management module. The supplementary terms can be determined according to specific business scenarios and business needs. The contract template management module can provide a variety of general contract templates and custom templates. The custom template can be the above-mentioned public contract template or private contract template.

[0066] In an embodiment of the present application, the template version number can be obtained by numbering iterative versions of the electronic contract template to obtain the version number corresponding to the current version of the electronic contract template (ie, the template version number).

[0067] For example, the electronic contract template has been changed three times. The version number corresponding to the original electronic contract template is set to v0, the version number corresponding to the electronic contract template after the first modification is v1, the version number corresponding to the electronic contract template after the second modification is v2, and the version number corresponding to the electronic contract template after the third modification is v3. The iterative versions are numbered in sequence, so that the number of times the electronic contract template is currently modified can be determined based on the version number, so that the modification order of each modification of the electronic contract template can be reflected, making supervision and auditing more convenient.

[0068] In addition, when saving the electronic contract template and the corresponding version number, you can also add the corresponding template modifier information, template modification time and other content to the version number, or record the corresponding modification information for each version number. The modification information includes the corresponding template modifier information, template modification time and other content, and the record information is also saved on the blockchain for better traceability, which helps to better conduct supervision and auditing.

[0069] Optionally, in the process of saving the electronic contract template and the corresponding version number on the blockchain, the electronic contract template and the corresponding version number can be saved on the blockchain in a hashing manner.

[0070] That is to say, the hash value of the electronic contract template and the hash value of the corresponding version number are saved on the blockchain, thereby ensuring the security, integrity, immutability and efficiency of the electronic contract template and the corresponding version number.

[0071] S102: When the electronic contract template is changed, the changed new electronic contract template and the corresponding version number are saved on the blockchain.

[0072] When the electronic contract template is changed, the new electronic contract template and the corresponding version number will also be saved on the blockchain, so that all versions of the electronic contract template and the version number corresponding to each version can be saved on the blockchain, which is convenient for controlling the version of the electronic contract template and facilitating supervision and auditing.

[0073] The process of saving the above-mentioned new electronic contract template and the corresponding version number to the blockchain is the same as the process of saving the electronic contract template and the corresponding version number to the blockchain in the aforementioned step S101, and will not be repeated here.

[0074] In addition, in order to improve the security of electronic contract templates (or new electronic contract templates), the access control mechanism of the blockchain can also be used to control the access rights of electronic contract templates (or new electronic contract templates) at different levels, so as to realize the refined permission management of electronic contract templates, thereby improving the security of electronic contract templates and reducing the risk of leakage of electronic contract templates.

[0075] Different access rights can be granted for different template types. For example, when the template type of an electronic contract template is a public contract template, all nodes on the blockchain can access the electronic contract template.

[0076] Optionally, after executing step S101 (i.e., saving the electronic contract template and the corresponding version number on the blockchain) or executing step S102 (i.e., saving the changed new electronic contract template and the corresponding version number on the blockchain), a target contract template can be selected from multiple electronic contract templates according to business needs to generate an electronic contract.

[0077] Specifically, according to business requirements, a target contract template is selected from multiple electronic contract templates. The target contract template meets the business requirements. Then, according to the target contract template and business parameters, an electronic contract is automatically generated, thereby realizing a quick start of electronic contract negotiations, greatly improving the efficiency of the contract negotiation process.

[0078] Among them, the structure definition of the electronic contract can be as follows:

[0079] {

[0080] ContractID / / Contract ID

[0081] TemplateID / / Template ID

[0082] ContractArgs / / Contract parameters

[0083] ContractFileHash / / Contract file hash

[0084] ContractStatus / / Contract status

[0085] }

[0086] Therefore, the electronic contract includes the contract ID, the template ID to which it belongs, the contract parameters, the contract file hash, and the contract status. Therefore, based on the contract ID, the template ID to which it belongs, the contract parameters, the contract file hash, and the contract status in the electronic contract, the current information of the electronic contract can be obtained to facilitate related processing.

[0087] The contract parameters may include information such as the storage location of the electronic contract, the properties of the electronic contract, etc. Therefore, the current information of the electronic contract can be obtained based on the contract parameters.

[0088] The contract status may include a drafting status, a signing status, an invalidation status, etc., so that the current status of the electronic contract can be known according to the contract status. For example, if the contract status is an invalidation status, it can be known that the electronic contract is currently invalidated according to the contract status.

[0089] In the embodiment of the present application, the target contract template is selected from multiple electronic contract templates according to business needs, and the target contract template can also be selected from multiple electronic contract templates and multiple built-in templates in the contract template management module according to business needs. That is, according to business needs, the target contract template that best meets the business needs is selected from multiple public contract templates, multiple private contract templates, and multiple built-in contract templates.

[0090] Optionally, in the process of selecting the target contract template from the electronic contract template according to business needs, it is also necessary to select the target contract template according to the template name, that is, select the target contract template from the electronic contract template according to business needs and the template name, so as to determine the required target contract template according to the template name.

[0091] Optionally, the above-mentioned electronic contract generation process can be automatically executed by a smart contract program, so that the business logic can be automatically executed through the smart contract program, and a template that meets business needs can be quickly generated, so that the efficiency of the electronic contract signing process can be improved. The smart contract program can be encoded according to the business logic. For example, the smart contract program can be encoded according to the electronic contract signing process.

[0092] Optionally, in the embodiment of the present application, the contract status of the electronic contract can also be tracked through the smart contract program, and the operation corresponding to the contract status can be executed. In addition, the key process in the automatic execution of the electronic contract can also be notified to the relevant parties (such as the participants of the electronic contract) through event notification, so that the participants of the electronic contract can know the status of the key process of the electronic contract in real time, so that they can make corresponding preparations for the key process to speed up the efficiency of the entire execution process of the electronic contract.

[0093] The above-mentioned key processes may include electronic contract signing processes such as contract drafting process, contract voting process, contract signing process, contract cancellation process, and contract storage process.

[0094] Furthermore, after the electronic contract is generated, each party to the electronic contract may be notified to digitally sign the electronic contract.

[0095] In the process of digitally signing electronic contracts by various participants, the electronic contracts can be digitally signed and verified based on the identity mechanism of the blockchain, thereby ensuring the correctness and security of the electronic contract signature.

[0096] In addition, in view of the large content of electronic contracts, a distributed storage system (English: InterPlanetary File System, abbreviated as IPFS system) is provided to store the generated electronic contracts.

[0097] The characteristic of the electronic contract having a large content is that the electronic contract has a large contract size or a large contract storage space. If it is determined that the contract size of the electronic contract is greater than the size threshold, then the contract size of the electronic contract is determined to be large; if it is determined that the contract storage space of the electronic contract is greater than the storage space threshold, then the contract storage space of the electronic contract is determined to be large.

[0098] That is to say, if it is determined that the contract size of the electronic contract is greater than the size threshold, or the contract storage space is greater than the storage space threshold, the electronic contract is stored in the IPFS system.

[0099] Since the IPFS system has the advantages of decentralization and efficient transmission, electronic contracts can be stored through the IPFS system, which prevents electronic contracts from being tampered with, ensures the authenticity and reliability of electronic contracts, further improves the security of electronic contracts, and at the same time improves the transmission efficiency of electronic contracts.

[0100] Optionally, after the electronic contract is generated, the signing record of the electronic contract can also be saved on the blockchain, so that the validity of the electronic contract can be proved at any time through the signing record, and the electronic contract can be traceable and auditable.

[0101] In addition, the electronic contract template in the embodiment of the present application has a scope of use. The scope of use can be adjusted according to the scope authorized by the creator of the electronic contract template, so that the electronic contract template is only used within the scope authorized by the creator of the electronic contract template to protect the rights and interests of the creator of the electronic contract template.

[0102] In summary, the data management method proposed in this application saves all versions of the electronic contract template and the version number corresponding to each version on the blockchain, making the version control of the electronic contract template simpler and convenient for audit traceability, so as to facilitate the supervision and audit of the entire process of the electronic contract template and ensure the data security in the electronic contract template.

[0103] In addition, uploading the summary content of the electronic contract template to the chain can prevent the electronic contract template from being tampered with, ensuring the authenticity of the electronic contract target. At the same time, the access control mechanism of the blockchain is used to control the access rights of the electronic contract template, realizing the refined permission management of the electronic contract template, which helps to reduce the risk of template leakage.

[0104] In addition, through the preset contract template structure data (such as electronic contract template), electronic contracts can be automatically generated according to business parameters, enabling the rapid start of electronic contract negotiations, greatly improving the efficiency of the contract negotiation process.

[0105] The technical solution of this application is further explained below in conjunction with a specific application process.

[0106] like Figure 2 The figure shows a processing diagram of the data management method. First, all versions of the electronic contract template and the corresponding version numbers are saved on the blockchain.

[0107] When the relevant party (such as the initiator of the electronic contract) initiates the contract signing, in the template generation module, according to the business needs corresponding to the contract signing initiated by the relevant party, the required built-in contract template is obtained from the contract template management module. Then, it is determined whether it is necessary to add supplementary clauses to the built-in contract template (that is, whether a personalized customized template is required). If it is necessary to add supplementary clauses to the built-in contract template (that is, a personalized customized template is required), the corresponding supplementary clauses are added to the built-in contract template, and then the template type is determined, which is a public contract template or a private contract template. If it is not necessary to add supplementary clauses to the built-in contract template (that is, no personalized customized template is required), the template type is directly determined. Then, according to the template type, a complete target contract template is obtained, and the target contract template is transmitted to the electronic contract generation module, so that the electronic contract generation module generates an electronic contract according to the target contract template. In addition, the target contract template and the corresponding version number are saved on the blockchain.

[0108] Alternatively, in the template generation module, according to the business requirements corresponding to the contract signing initiated by the relevant parties, the required version of the electronic contract template is directly obtained from the blockchain. The electronic contract template is used as the target contract template. The target contract template is then transmitted to the electronic contract generation module, so that the electronic contract generation module generates an electronic contract according to the target contract template.

[0109] In the electronic contract generation module, the target contract template generated in the template generation module is obtained, and then the electronic contract is automatically generated according to the target contract template and business parameters.

[0110] Furthermore, each party to the electronic contract digitally signs the electronic contract.

[0111] Next, in the smart contract module, each process of the electronic contract is executed and the contract status of the electronic contract is monitored.

[0112] Finally, the signing record of the electronic contract is saved on the blockchain.

[0113] Based on the same inventive concept, the present application also provides a data management device, such as Figure 3 The figure is a schematic diagram of the structure of a data management device provided by the present application, the device comprising:

[0114] In a second aspect, the present application further provides a data management device, the device comprising:

[0115] The on-chain module 301 is used to store the electronic contract template and the corresponding version number on the blockchain;

[0116] The processing module 302 is used to save the changed new electronic contract template and the corresponding version number on the blockchain when the electronic contract template is changed.

[0117] In a possible implementation, the on-chain module 301 is specifically used to save the summary content of the electronic contract template, including the template identification code ID, template name, template file hash value hash, template creation time, template creator, template type, and template version number, to the blockchain.

[0118] In a possible implementation, the device further includes an access control module, and the access control module is used to control access rights to the electronic contract template by utilizing an access control mechanism of the blockchain.

[0120] In a possible implementation, the processing module 302 is specifically configured to store the electronic contract in a distributed storage system IPFS system if it is determined that the contract size of the electronic contract is greater than a size threshold or the contract storage space is greater than a storage space threshold.

[0121] In a possible implementation, the processing module 302 is specifically configured to save the signing record of the electronic contract on the blockchain.

The specific connection medium between the processor 401 and the memory 402 is not limited in the embodiment of the present application. Figure 4 In the example, the processor 401 and the memory 402 are connected via the bus 400. The bus 400 is Figure 4 The connection between other components is shown by bold lines, and is not intended to be limiting. The bus 400 can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 4 Only one thick line is used in the figure, but it does not mean that there is only one bus or one type of bus. Alternatively, the processor 401 can also be called a controller, and there is no limitation on the name.

[0125] In the embodiment of the present application, the memory 402 stores instructions that can be executed by at least one processor 401.

It is understandable that the modem processor may not be integrated into the processor 401. In some embodiments, the processor 401 and the memory 402 may be implemented on the same chip, and in some embodiments, they may also be implemented separately on separate chips.
