All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Method embodiment one

Referring to fig. 1, the figure is a flowchart of an information management method according to an embodiment of the present application.

The information management method provided by the embodiment of the application comprises the following steps of S101-S103:

s101: after a target contract is obtained, a target contract identifier is generated according to the target contract, and the target contract identifier are stored in a first block of a block chain.

The target contract identification is used to uniquely identify the target contract.

The target contract is a contract which needs to be stored and managed; moreover, the embodiment of the present application does not limit the manner of acquiring the target contract. For ease of understanding and explanation, the following description is made in conjunction with two examples.

As a first example, the target contract may be obtained by: and generating the target contract according to the contract template and the characteristic information of the target contract. The contract template can be acquired from a preset storage unit, and can also be received from a template sent by a user by using an input device. The characteristic information of the target contract is used for representing the content which needs to be added into the contract template in the target contract; moreover, characteristic information for the target contract can be generated from the target contract and the contract template.

As a second example, the target contract may be obtained by: and receiving a target contract sent by the preset equipment. The preset device may be a terminal device or a server, and for example, the preset device may be an input device such as a scanner or a camera.

Based on the above, when the information management method is applied to the contract management system, the user (party a or party b) can edit the content using the standard contract template or the personalized contract template provided by the contract management system to obtain the target contract, or can edit the content using the contract template provided by the user to obtain the target contract, or can directly convert the paper version target contract into the electronic version target contract using the input device such as the scanner or the camera, and import the electronic version target contract into the contract management system for storage.

Based on the above content, in the embodiment of the application, after the target contract is obtained, the target contract identifier may be generated according to the target contract, and then the target contract and the target contract identifier are stored in the first block of the block chain, so that the target contract stored in the first block can be obtained based on the target contract identifier in the subsequent information tracing process.

In addition, since the requirement of the contract file for the storage space is usually large, in this case, in order to reduce the storage pressure of the blockchain, the fingerprint (e.g., hash value) of the contract file may be stored in the blockchain. Based on this, the embodiment of the present application further provides a specific implementation manner of step S101, in this implementation manner, S101 may specifically be: and generating a hash value of the target contract according to the target contract, and storing the hash value of the target contract and the target contract identifier into a first block of the block chain.

In this embodiment, after the target contract is obtained, the hash value of the target contract may be generated according to the target contract, and the target contract identifier may be generated according to the target contract; and then the hash value of the target contract and the target contract identification are stored in a first block of the block chain. In this way, in the subsequent information tracing process, the target contract can be inquired according to the hash value of the target contract stored in the first block; and the query process may include: the method comprises the steps of firstly carrying out Hash calculation on storage files in a storage space to obtain Hash values of the storage files, matching the Hash values of target contracts with the Hash values of the storage files, and determining the successfully matched storage files as the target contracts. The first block only needs to store the hash value of the target contract with the small size, and the target contract file with the large size does not need to be stored, so that the storage pressure of the first block is reduced, and the storage pressure of the block chain is reduced.

Note that, the first block also stores therein a timestamp for generating the first block. In addition, when the hash value of the target contract is stored in the first block, the target contract may be stored in the storage space so that the target contract can be subsequently queried based on the hash value of the target contract stored in the first block.

S102: and when the completion progress self-evidence material corresponding to the target contract is obtained, storing the completion progress self-evidence material and the target contract identification into a second block of the block chain.

And the completion progress self-certification material is used for certifying the completion progress of the policy B on the target contract. For example, the completion progress self-certified material may include materials such as delivery notes, logistics information, project progress reports, and product photographs.

In this embodiment of the application, when the information management method is applied to the contract management system, after the second party starts to execute the project corresponding to the target contract, the user (the first party or the second party) may first upload the completion progress self-certified material corresponding to the target contract to the contract management system (or fill the completion progress self-certified material in a designated area), and then the contract management system stores the completion progress self-certified material and the target contract identifier in the second block of the block chain, so that the completion progress self-certified material stored in the second block can be acquired based on the target contract identifier in the subsequent information tracing process.

In addition, since the requirement of the completion progress self-certified material for the storage space is usually large, in this case, in order to reduce the storage pressure of the blockchain, a fingerprint (e.g., a hash value) of the completion progress self-certified material may be stored in the blockchain. Based on this, the embodiment of the present application further provides a specific implementation manner of step S102, in this implementation manner, S102 may specifically be: and generating the hash value of the completion progress self-certified material according to the completion progress self-certified material, and storing the hash value of the completion progress self-certified material and the target contract identification into a second block of the block chain.

In the embodiment of the application, after the completion progress self-certified material is acquired, the hash value of the completion progress self-certified material can be generated according to the completion progress self-certified material, and then the hash value of the completion progress self-certified material and the target contract identifier are stored in the second block of the block chain. Therefore, in the subsequent information tracing process, the completion progress self-verification material can be inquired according to the hash value of the completion progress self-verification material stored in the second block; and the query process may include: the method comprises the steps of firstly carrying out Hash calculation on storage files in a storage space to obtain Hash values of the storage files, matching the Hash values of progress self-certification materials and the Hash values of the storage files, and determining the successfully matched storage files as the progress self-certification materials. The second block only needs to store the hash value of the completion progress self-certification material with the small storage volume, the completion progress self-certification material file with the large storage volume is not needed, and the storage pressure of the second block is reduced, so that the storage pressure of the block chain is reduced.

It should be noted that, in this embodiment, when the hash value of the completion progress self-certified material is stored in the second block, the completion progress self-certified material may be stored in the storage space, so that the completion progress self-certified material can be subsequently queried based on the hash value of the completion progress self-certified material stored in the second block.

In addition, in order to facilitate that a self-certified material of completion progress can be quickly found in a subsequent tracing process, an embodiment of the present application further provides another implementation manner of S102, where S102 may include: and when the completion progress self-certified material corresponding to the target contract is obtained, generating a completion progress self-certified material identifier according to the completion progress self-certified material, and storing the completion progress self-certified material, the completion progress self-certified material identifier and the target contract identifier into a second block of the block chain.

And the completion progress self-evidence material identification is used for uniquely identifying the completion progress self-evidence material.

In this embodiment, after the completion progress self-certified material corresponding to the target contract is obtained, the completion progress self-certified material identifier is generated according to the completion progress self-certified material, and then the completion progress self-certified material, the completion progress self-certified material identifier and the target contract identifier are stored in the second block of the block chain, so that the second block can be directly searched from the block chain based on the completion progress self-certified material identifier in the subsequent information tracing process, and the completion progress self-certified material is obtained from the second block. Therefore, the tracing efficiency of the self-certified materials for completing the progress is improved.

Note that, the second block also stores a timestamp for generating the second block.

S103: and when the acceptance information corresponding to the target contract is obtained, storing the acceptance information and the target contract identification in a third block of the block chain.

And the acceptance information is used for recording the acceptance result of the first party for the execution result of the target contract. Wherein the target contract is generated for the purpose of maintaining the rights and interests of the execution result of the target contract; also, the execution result of the target contract may be an object (e.g., product, etc.), a project, a relationship, and the like.

In this embodiment of the application, when the information management method is applied to the contract management system, after the second party completes the project corresponding to the target contract and obtains the execution result of the target contract, the user (the first party) may first check the execution result of the target contract to obtain the acceptance information corresponding to the target contract, upload the acceptance information corresponding to the target contract to the contract management system, and then store the acceptance information and the target contract identifier into the third block of the block chain by the contract management system, so that the acceptance information stored in the third block can be obtained based on the target contract identifier in the subsequent information tracing process.

In addition, since the storage requirement of the acceptance information is usually large, in this case, in order to reduce the storage pressure of the block chain, a fingerprint (for example, a hash value) of the acceptance information may be stored in the block chain. Based on this, the embodiment of the present application further provides a specific implementation manner of step S103, and in this implementation manner, S103 may specifically be: and generating a hash value of the acceptance information according to the acceptance information, and storing the hash value of the acceptance information and the target contract identifier into a third block of the block chain.

In the embodiment of the application, after the acceptance information is acquired, the hash value of the acceptance information may be generated according to the acceptance information, and then the hash value of the acceptance information and the target contract identifier are stored in the third block of the block chain. In this way, in the subsequent information tracing process, the acceptance information can be inquired according to the hash value of the acceptance information stored in the third block; and the query process may include: the method comprises the steps of carrying out Hash calculation on storage information in a storage space to obtain a Hash value of the storage information, matching the Hash value of acceptance information with the Hash value of the storage information, and determining the successfully matched storage information as the acceptance information. The third block only needs to store the hash value of the acceptance information with small volume, so that the acceptance information file with large storage volume is not needed, the storage pressure of the third block is reduced, and the storage pressure of the block chain is reduced.

In this embodiment, when the hash value of the acceptance information is stored in the third block, the acceptance information may be stored in the storage space so that the acceptance information can be subsequently queried based on the hash value of the acceptance information stored in the third block.

In addition, in order to facilitate that the acceptance information can be quickly found in the subsequent tracing back process, the embodiment of the present application further provides another implementation manner of S103, where in this implementation manner, S103 may include: and when the acceptance information corresponding to the target contract is obtained, generating an acceptance information identifier according to the acceptance information, and storing the acceptance information, the acceptance information identifier and the target contract identifier into a third block of the block chain.

And the acceptance information identification is used for uniquely identifying the acceptance information.

In this embodiment, after the acceptance information corresponding to the target contract is obtained, the acceptance information identifier is generated according to the acceptance information, and then the acceptance information, the acceptance information identifier, and the target contract identifier are stored in the third block of the block chain, so that the third block can be directly searched from the block chain based on the acceptance information identifier in the subsequent information tracing process, and the acceptance information is obtained from the third block. Thus, the tracing efficiency of the acceptance information is improved.

Method embodiment two

For the sake of brevity, the same contents as those in the first method embodiment are not described again.

In addition, an embodiment of the present application further provides another implementation of the information management method, and in this implementation, as shown in fig. 2, the information management method may further include, in addition to the above steps, S104:

s104: and when a correction contract corresponding to the target contract is obtained, storing the correction contract and the target contract identification in a fourth block of the block chain.

The revised contract refers to a contract obtained after content modification or adjustment is performed on a target contract.

In the embodiment of the application, when the information management method is applied to the contract management system, after a user (a party a or a party b) views a target contract, the user may modify or adjust the target contract according to a self requirement to obtain a corrected contract, so that when the contract management system obtains the corrected contract corresponding to the target contract, the corrected contract and the target contract identifier are stored in a fourth block of the block chain.

It should be noted that the acquiring manner of the correction contract may include: and the user directly modifies the target contract in the contract management system to obtain a corrected contract. The acquisition method of the correction contract may include: and receiving a correction contract sent by the preset equipment. The preset device may be a terminal device or a server, and for example, the preset device may be an input device such as a scanner or a camera.

Based on the above, in the embodiment of the application, after the correction contract corresponding to the target contract is obtained, the correction contract and the target contract identifier may be stored in the fourth block of the block chain, so that the correction contract stored in the fourth block can be obtained based on the target contract identifier in the subsequent information tracing process.

In addition, since the requirement of the contract file for the storage space is usually large, in this case, in order to reduce the storage pressure of the blockchain, a fingerprint (e.g., a hash value) of the correction contract may be stored in the blockchain. Based on this, the embodiment of the present application further provides a specific implementation manner of step S104, in this implementation manner, S104 may specifically be: and generating a hash value of the correction contract according to the correction contract, and storing the hash value of the correction contract and the target contract identifier into a fourth block of the block chain.

In the embodiment of the application, after the correction contract is acquired, the hash value of the correction contract may be generated according to the correction contract, and then the hash value of the correction contract and the target contract identifier may be stored in the fourth block of the block chain. In this way, in the subsequent information tracing process, the correction contract can be inquired according to the hash value of the correction contract stored in the fourth block; and the query process may include: the method comprises the steps of firstly carrying out Hash calculation on storage files in a storage space to obtain Hash values of the storage files, matching the Hash values of correction contracts with the Hash values of the storage files, and determining the successfully matched storage files as correction contracts. The fourth block only needs to store the hash value of the correction contract with a small size, and the correction contract file with a large size does not need to be stored, so that the storage pressure of the fourth block is reduced, and the storage pressure of the block chain is reduced.

It should be noted that, in this embodiment, when the hash value of the correction contract is stored in the fourth block, the correction contract may be stored in the storage space so that the correction contract can be queried subsequently based on the hash value of the correction contract stored in the fourth block.

In addition, in order to facilitate that a correction contract can be quickly found in a subsequent tracing process, the embodiment of the present application further provides another implementation manner of S104, where S104 may include: and when a correction contract corresponding to the target contract is obtained, generating a correction contract identifier according to the correction contract, and storing the correction contract, the correction contract identifier and the target contract identifier into a fourth block of the block chain.

Wherein, the correction contract identification is used for uniquely identifying the correction contract.

In this embodiment, after the correction contract corresponding to the target contract is acquired, the correction contract identifier is generated according to the correction contract, and then the correction contract, the correction contract identifier and the target contract identifier are stored in the fourth block of the block chain, so that the fourth block can be directly searched from the block chain based on the correction contract identifier in the subsequent information tracing process, and the correction contract is acquired from the fourth block. Therefore, the tracing efficiency of contract correction is improved.

Note that, the fourth block also stores a timestamp generated by the fourth block.

The above is another implementation manner of the information management method provided in the embodiment of the present application.

In addition, in order to improve the information management capability of the contract, the intelligent contract of the block chain may be applied to the information management method of the contract. Based on this, the present application provides still another implementation manner of the information management method, in this implementation manner, as shown in fig. 3, the information management method may include, in addition to the above steps, S105 to S107:

s105: after the acceptance information corresponding to the target contract is obtained, the target contract in the first block and the completion progress self-certification material in the second block are obtained according to the target contract identification.

If there is a correction contract of the target contract in the blockchain, S105 may specifically be: after the acceptance information corresponding to the target contract is obtained, the correction contract in the fourth block and the completion progress self-certification material in the second block are obtained according to the target contract identification.

It should be noted that the execution purpose of S105 is to obtain the final version of the contract from the blockchain and the completion progress self-evidence material provided by the second party, so that the execution strength of the second party on the final version of the contract can be determined based on the information.

S106: and determining contract fulfillment information according to the target contract and the completion progress self-evidence material.

Wherein, the contract execution information is used for recording the execution information of the target contract upper clause of the second party. That is, the contract performance information is used to record the execution strength information of the second party on the terms on the target contract.

S107: storing the contract performance information and the target contract identification in a fifth block of a block chain.

Based on the above, in this embodiment, when the information management method is applied to the contract management system, after the contract management system obtains the acceptance information corresponding to the target contract, the contract management system may first obtain the target contract in the first block and the completion progress self-certified material in the second block according to the target contract identifier, then determine the contract fulfillment information according to the target contract and the completion progress self-certified material, and store the contract fulfillment information and the target contract identifier into the fifth block of the block chain by the contract management system, so that the contract fulfillment information stored in the fifth block can be obtained based on the target contract identifier in the subsequent information tracing process. The contract management system can automatically determine the execution strength of the second party to the target contract treaty according to the information of the second party on the contract execution and the treaty information on the contract, so that the subsequent payment or reward punishment can be automatically carried out based on the execution strength of the second party to the target contract treaty.

In addition, since the requirement of the contract fulfillment information for the storage space is usually large, in order to reduce the storage pressure of the blockchain, fingerprints (e.g., hash values) of the contract fulfillment information may be stored in the blockchain. Based on this, the embodiment of the present application further provides a specific implementation manner of step S107, in this implementation manner, S107 may specifically be: generating a hash value of the contract fulfillment information from the contract fulfillment information, and storing the hash value of the contract fulfillment information and the target contract identification in a fifth block of the chain of blocks.

In this embodiment of the application, after the contract fulfillment information is obtained, a hash value of the contract fulfillment information may be generated according to the contract fulfillment information, and then the hash value of the contract fulfillment information and the target contract identifier may be stored in a fifth block of the block chain. In this way, in the subsequent information tracing process, the contract fulfillment information can be queried according to the hash value of the contract fulfillment information stored in the fifth block; and the query process may include: the method comprises the steps of firstly carrying out hash calculation on a storage file in a storage space to obtain a hash value of the storage file, matching the hash value of contract fulfillment information with the hash value of the storage file, and determining the successfully matched storage file as the contract fulfillment information. The fifth block only needs to store the hash value of the contract fulfillment information with a small volume, and the contract fulfillment information file with a large volume does not need to be stored, so that the storage pressure of the fifth block is reduced, and the storage pressure of the block chain is reduced.

It should be noted that, in this embodiment, when the hash value of the contract fulfillment information is stored in the fifth block, the contract fulfillment information may be stored in the storage space so that the contract fulfillment information can be subsequently queried based on the hash value of the contract fulfillment information stored in the fifth block.

The sixth block only needs to store the hash value of the small reward punishment information, the large reward punishment information file does not need to be stored, and the storage pressure of the sixth block is reduced, so that the storage pressure of the block chain is reduced.

It should be noted that, in this embodiment, when the hash value of the reward punishment information is stored in the sixth block, the reward punishment information may be stored in the storage space, so that the reward punishment information can be queried based on the hash value of the reward punishment information stored in the sixth block in the following process.

In addition, in order to facilitate that reward and punishment information can be quickly found in a subsequent tracing back process, an embodiment of the present application further provides another implementation manner of S109, where S109 may include: when the reward punishment information corresponding to the target contract is obtained, generating a reward punishment information identification according to the reward punishment information, and storing the reward punishment information, the reward punishment information identification and the target contract identification into a sixth block of the block chain.

And the reward and punishment information identification is used for uniquely identifying reward and punishment information.

In this embodiment, after the reward and punishment information corresponding to the target contract is acquired, the reward and punishment information identifier is generated according to the reward and punishment information, and then the reward and punishment information, the reward and punishment information identifier and the target contract identifier are stored in the sixth block of the block chain, so that the sixth block can be directly found from the block chain based on the reward and punishment information identifier in the subsequent information tracing process, and the reward and punishment information is acquired from the sixth block. Therefore, the tracing efficiency of reward and punishment information is improved.

Note that, the sixth block also stores therein a time stamp of the sixth block.

In addition, based on the specific implementation of the information management method provided above, in the embodiment of the present application, the processes of contract initiation, modification, execution, acceptance check, financial settlement, reward and punishment, and the like, may be automatically performed by using a block chain, and information in each corresponding process is recorded. Thus, the intelligent management of contract information is realized.

In addition, the information management method provided by the embodiment of the present application can be applied to a third party platform or a matching platform (the platform functions are shown in fig. 5), for example, an enterprise manages a contract management system (or platform) as an intermediary party, and a party a and a party b of a contract can directly implement creation and approval of contract contents, implement management of contract versions, implement execution of contract terms and financial payment, and other contents related to all contracts on the contract management system (or platform) according to the agreement contents to be achieved for offline and online transactions and services. Therefore, the block chain storage-based contract is true, credible and extremely credible for both parties A and B, and the reasons are as follows:

(1) a contract management platform (that is, a contract management system having an information management method) which is publicly transparent and trusted is established: the service management, the contract management and the block chain technology are effectively combined to establish a public and transparent contract management and service management platform.

(2) E, contract electronization: and the service of contract auditing is transferred from off-line to on-line, so that the electronization of the contract is realized.

(3) Contract standardization: the non-standard contracts are gradually transited to the standard contracts, and the enterprise management is standardized. For example, the target contract is generated by utilizing a contract template.

(4) And (3) expanding the contract management range: in addition to generating and storing the contract, ancillary terms of the contract (e.g., payment, acceptance, reward and punishment, etc.) are all implemented on-line, enhancing risk management of the contract, reducing potential financial risk

(5) The service flow is simplified: business, legal affairs and finance are carried out in a system to complete the operation of each business department,

(6) integrating contract management with intelligent contracts: the invention combines the contract with the intelligent block chain contract, and can realize the effective combination of contract execution, audit and payment.

(7) Introduction of an incentive mechanism: based on the platform disclosure transparent feature, various incentive mechanisms can be introduced to participants in the scheme under the condition that the contract content service is guaranteed to be executed as scheduled on time, and the platform participants are estimated to execute terms actively according to the regulations.

It should be noted that, in the above method embodiment, the execution sequence and the connection relationship of the first block to the sixth block are not limited, that is, the first block to the sixth block may be connected adjacently or not. The reason is as follows: since the blocks are generated according to time, the first to sixth blocks may be generated at adjacent time points or may be generated at intervals of a long time, so that the first to sixth blocks may be connected adjacently or not.
