Detailed Description
The embodiments of the present invention will be described below with reference to the drawings.
With the advent of the law-governing society and the law-governing era, more and more citizens choose to make a daily order before life, and reasonably distribute personal property and process personal affairs by legal means. In order to help the testimonial will person to properly manage the testimonial will information, various testimonial will information management platforms, such as notary department, testimonial will box, etc., come into play. The method comprises the steps that a public department, a box and other advice information management platforms manage the advice information by means of a database, and the advice information is stored in the database in a classified mode. In the mode of managing the information of the will advice by means of the database, the information of the will advice is easily damaged or lost under the conditions that the database is attacked by lawless persons, the database system is crashed or the storage space of the database is exhausted, and the reliability of the information of the will advice is low.
In order to solve the above problem, an embodiment of the present invention introduces a block chain technique into a management manner of the will-information, and provides an information management method and a related device, where the method specifically may be: the information management device checks the received testimony information, checks whether the testimony information is notarized or not, and sends the testimony information to a notarization department if the testimony information is not notarized, and after notarization by the notarization department, the information management device generates blocks of the notarized testimony information and uploads the blocks to a block chain network; and if the testimony information is notarized, directly generating a block by the testimony information and uploading the block to a block chain network.
The will information may include identity information and content of the will, and the identity information related to this embodiment may be information that can prove the identities of the person who orders the will and the beneficiary of the will, such as an identity card copy, an identity card scan, a fingerprint, and the like, which is not limited herein. The identity information may include an identity identifier that uniquely identifies the identity information, where the identity identifier may be an identification number, and is not limited herein. The content of the will order related to this embodiment includes, but is not limited to, an electronic file of the will order, an electronic official book of the will order, and the electronic file of the will order, the electronic official certificate of the will order may include a tag of the will order and an electronic certificate, which is not limited herein. The will-order identification can be a number sequence, an alphabet sequence or a number-alphabet combination sequence which uniquely identifies the will-order information; the electronic certificate may be a official seal or a handwritten signature specially made by the national justice department, which is not limited herein. In a specific application scenario, the will-order information may further include other materials, and the other materials included in the will-order information may be determined according to actual needs, for example, the will-order content including a house property distribution situation may further include house property registration information, the will-order content including a money distribution situation may further include bank account information, and the like.
The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and a distributed account book which ensures data to be not falsified and forged in a cryptographic mode is provided. A plurality of independent distributed nodes (namely block chain link point devices) store the same record, the block chain technology realizes decentralization, and the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like.
Taking the schematic structural diagram of the block chain shown in fig. 1 as an example, when there is a wishlist information to be written into the block chain, the wishlist information is gathered into one block, a timestamp uniquely identifying the generation time of the new block is generated while a new block is generated according to the wishlist information, the new block is added to the end of the existing block chain according to the sequence of the timestamps, it should be noted that after the new block is generated, the new block and the timestamp uniquely identifying the generation time of the new block are broadcast and sent to each block chain node device in the block chain network, and the timestamp guarantees the accuracy of the generation time of the new block, so that the accuracy of the time for uploading the wishlist information to the block chain network is guaranteed. In the block chain network, the newly added blocks of each block chain link point device in each block chain network are ensured to be completely the same through a consensus algorithm. A plurality of pieces of will information are recorded in each block, the hash value of the previous block is contained, and all the blocks are connected in sequence by storing the information in the previous block to form a block chain. If the information in a block in the blockchain network is changed, the hash root of the merkel tree in the block is changed, and further the hash value of the block head in the block is changed, so that the hash value of the previous block head stored in the block head of the block behind the block is not matched with the hash value of the block head of the block, once the information in a certain block is changed, all subsequent blocks need to be changed to ensure that the change cannot be found, and therefore, the will-know-how information generation block is difficult to tamper after being uploaded to the blockchain network.
The block chain technology is introduced into a management mode of the testament information, the testament information generates blocks and is distributed after the block chain network, the testament information is stored in each block chain node device of the block chain network in a distributed mode, and a complete and non-modifiable electronic data is formed, so that the management of the testament information is safer, and the reliability of the testament information is improved.
In order to better understand an information management method and related devices disclosed in the embodiments of the present invention, a communication system to which the embodiments of the present invention are applicable is first described below.
Referring to fig. 2, fig. 2 is a schematic diagram of a communication system according to an embodiment of the present invention. As shown in fig. 2, the communication system includes an information management device 202, a second block-link-point device 203, and at least one first block-link-point device 201, where the first block-link-point device 201, the information management device 202, and the second block-link-point device 203 form a block chain network. It should be noted that the block chain network shown in fig. 2 is composed of a first block chain node device 201, an information management device 202, and a second block chain node device 203, which are only used for illustration and do not constitute a limitation to the embodiments of the present invention.
The information management apparatus 202 is obtained by selecting all the block link node apparatuses in the block chain network according to a consensus algorithm, wherein the consensus algorithm includes, but is not limited to, a Proof of Work (PoW) algorithm, a Proof of rights of sale (PoS) algorithm, a Proof of authorized rights of sale (DPoS) algorithm, a Practical Byzantine Fault Tolerance (PBFT) algorithm, and the like.
In one implementation, all the blockchain link point devices in the blockchain network may elect the information management device according to a certain period, and the information management devices obtained by election in different periods may be different. The information management device may be configured to pack transactions that are currently generated in the blockchain network and that have not been packed, generate a block, and issue the block to the blockchain network. The information management device may be any one of the block link node devices in the block chain network, for example, the information management device may be a first block link node device, a second block link node device, or another block link node device in the block chain network.
In one implementation, the second block node device may be a block link node device corresponding to a notary department. It should be noted that the block link point device corresponding to the notarization department is the second block link point device only for example, the block link point device corresponding to the notarization department may be any one block link point device in the block chain network, the block chain management device corresponding to the notarization department may be the first block link point device, the block link point device corresponding to the notarization department may be the second block link point device, the block link point device corresponding to the notarization department may be the third block link node device, and so on. The block chain link point devices corresponding to the notarization departments can also be periodically elected by all the block chain link point devices in the block chain network, the block chain link point devices corresponding to the notarization departments obtained by electing in different periods can be different, and the block chain link point devices corresponding to the notarization departments can also be fixed and unchangeable.
For example, in the scene of the wishlist information management, the information management device can be a block chain link point device corresponding to a functional department, the second block chain link point device can be a block chain link point device corresponding to a notary department, the functional department checks the wishlist information after receiving the wishlist information, when the functional department fails to check the wishlist information, the functional department sends the wishlist information to the notary department, and after the notary department notarizes the wishlist information, the functional department generates the wishlist information into a block and distributes the block to a block chain network; and when the functional department successfully verifies the testimony information, the functional department generates a block from the testimony information and distributes the block to the block chain network. In this way, the will information is permanently stored in the blockchain network, so that the will information has higher stability and reliability.
It should be understood that the communication system described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and as a person having ordinary skill in the art knows that along with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.
Based on the schematic architecture diagram of a communication system shown in fig. 2, please refer to fig. 3, and fig. 3 is a schematic flow chart of an information management method according to an embodiment of the present invention, where the method includes, but is not limited to, the following steps:
step S301: the information management device receives first will information from the first block link point device.
For example, the information management device may receive the first will information from the first block-linked point device, the information management device may receive the first will information from the second block-linked point device, and so on. The first will information received by the information management apparatus may also be submitted to the information management apparatus by the user. The information management device may be configured to distribute the received first will information to the blockchain network. The information management device is obtained by selecting all the block chain link point devices in the block chain network according to a consensus algorithm, so that the reliability of the data issued by the information management device is high. In a block chain network including at least an information management device, a first block chain node device, and a second block chain node device, the information management device is periodically selected from all the block chain devices in the block chain network by a consensus algorithm before all transactions.
Step S302: the information management device verifies the first will information.
In one implementation, when the information management apparatus does not acquire the electronic certificate of the first will information, the information management apparatus determines that the verification of the first will information fails, indicating that the first will information is not notarized. When the first will information includes the electronic voucher, the information management device determines that the first will information is successfully verified. Taking an electronic voucher as a special official seal of a national department of justice as an example, in the scene of the management of the testimony information, after the functional department receives the testimony information, whether the testimony information contains the official seal is checked. If the testimony information contains official seal, the testimony information is proved; if the information of the will order does not include the official seal, it indicates that the information of the will order is not notarized, and the notarization department needs to send the information of the will order to the notarization department, and the notarization department notarizes the information of the will order. If the notarization department succeeds in notarizing the testimony information, the testimony information obtains a corresponding official seal; if the notary department fails to notarize the information of the testimony, the notary department can send a testimony failure notice of the testimony information to the functional department, and the testimony failure notice of the testimony information is used for indicating the testimony of the testimony information that the notary department fails to notarize the testimony information to the functional department.
In one implementation, when the information management apparatus does not acquire the will label of the first will information, it indicates that the first will information is not notarized, and the information management apparatus determines that the verification of the first will information fails. When the first will information includes the will identification, the information management device determines that the first will information is verified successfully. Taking the numerical sequence for uniquely identifying the first will information by using the will information identifier as an example, in the scene of the management of the will information, after the functional department receives the will information, checking whether the number sequence is contained in the will information. If yes, indicating that the will information is notarized; if the testimony information does not contain the numerical sequence, the testimony information is required to be sent to a notarization department, and the notarization department notarizes the testimony information. If the notarization department succeeds in notarizing the testimony information, the testimony information obtains a corresponding numerical sequence; if the notary department fails to notarize the information of the testimony, the notary department can send a testimony failure notice of the testimony information to the functional department, and the testimony failure notice of the testimony information is used for indicating the testimony of the testimony information that the notary department fails to notarize the testimony information to the functional department.
In one implementation, the information management apparatus may obtain a first identification identifier in the first will information identification information and a second identification identifier in the content of the will, and when the first identification identifier and the second identification identifier are the same, the information management apparatus determines that the first will information is successfully verified. Illustratively, taking the content of the will advice as the electronic file of the will advice and the identity mark as the identification number as an example, in the management scene of the information of the will advice, the functional department can obtain the identification number of the person who subscribes the will advice in the identity information and the identification number of the person who subscribes the will advice in the electronic file of the will advice, and when the identification number of the person who subscribes the will in the identity information and the identification number of the person who subscribes the will advice in the electronic file of the will advice are the same, the functional department successfully verifies the first information of the will advice. The functional department can also acquire the identification number of the beneficial person of the wisdom advice in the identity information and the identification number of the beneficial person of the wisdom advice in the wisdom electronic file, and when the identification number of the beneficial person of the wisdom advice in the identification information is the same as the identification number of the beneficial person of the wisdom advice in the wisdom electronic file, the functional department determines that the verification of the first wisdom advice information is successful, wherein the wisdom advice beneficial person can be one or more. When the will-order beneficiary is multiple, the identification number of each will-order beneficiary in the first will-order information identity information should correspond to the identification number of each will-order beneficiary in the first will-order information electronic file one by one, for example, the will-order electronic file includes a first will-order beneficiary, a second will-order beneficiary and a third will-order beneficiary, when the identification number of the first will-order beneficiary in the first will-order information identity information is the same as the identification number of the first will-order beneficiary in the first will-order information electronic file, the identification number of the second will-order beneficiary in the first will-order information identity information is the same as the identification number of the second will-order beneficiary in the first will-order information electronic file, and the identification number of the third will-order beneficiary in the first will-order information electronic file is the same as the identification number of the first will-order beneficiary in the first will-order information electronic file, and the functional department determines that the first will information is successfully verified.
In one implementation, the information management device may obtain an electronic certificate of the testament content, compare the electronic certificate with at least one electronic certificate in a preset database, and when the electronic certificate exists in the preset database, the information management device determines that the first testament information is successfully verified. Taking an electronic certificate as a specially-made official seal of a national justice department and the content of the testimony as an example, the information management device acquires the official seal in the electronic official document of the testimony and compares the official seal in the electronic official certificate of the testimony with a specially-made official seal set of the national justice department in a preset database, and when the official seal set of the electronic official seal of the testimony exists in the specially-made official seal set of the national justice department in the preset database, the information management device determines that the first testimony information is successfully verified.
In one implementation, if the information management device fails to verify the first will information, the information management device may send a failure notification of the verification of the first will information to the first block link point device, where the failure notification of the verification of the first will information is used to indicate to the first block link point device that the information management device fails to verify the first will information, and the information management device may delete the first will information.
Through this kind of mode, the final testimony information that uploads to the block chain network of information management device is the testimony information that passes through the check-up, is the testimony and has the testimony's testimony and the testimony's testimony of a general advice information promptly, can realize the unification to testimony information, the convenient management to testimony information.
Step S303: and when the information management device successfully verifies the first will information, the information management device generates a second block according to the first will information.
In one implementation, when the information management device successfully verifies the first will information, the information management device sends the first will information to each block link node device in the block chain network. It should be noted that fig. 2 exemplifies that the blockchain network is composed of a first blockchain link point device, a second blockchain link point device and an information management device, and accordingly, in the embodiment of the present invention, each blockchain link point device in the blockchain network specifically refers to the first blockchain link point device and the second blockchain link point device. It should be noted that the block chain network at least includes a first block chain link point device and a second block chain link point device, and in other possible implementations, the block chain network may further include an information management device, a first block chain link point device, a second block chain link point device, and a third block chain link node device, which is not limited in this embodiment of the present invention.
In one implementation, after the information management device sends the first wishlist information to each block chain node device in the block chain network, each block chain node device in the block chain network checks the first wishlist information, and sends a check result of the first wishlist information to the information management device. Specifically, the manner in which each block link node device in the block chain network checks the first will information may be referred to in the detailed description of step S302 in the embodiment of the present invention, and is not described herein again.
In one implementation, the information management device receives a verification result of the first will information from each block link node device in the block chain network. The verification results of the first will information from each block chain node device in the block chain network may be independent of each other, that is, the verification process performed by each block chain node device on the first will information may not be affected by other block chain node devices. For example, the result of the verification of the first will information from the first block-linked dot device may be a successful verification, and the result of the verification of the first will information from the second block-linked dot device may be a failed verification. And after each block chain link point device in the block chain network checks the first will information, the checking result is sent to the information management device.
In one implementation, when the number of successful verification results in the verification results received by the information management device is greater than or equal to the preset number threshold, the information management device may determine that the first will order information passes through the verification of the block chain network, and the information management device generates the second block according to the first will order information. The preset number threshold may be one half, two thirds, or three quarters of the number of each block link point device in the block link network, which is not limited in this embodiment. Using a preset quantity threshold value as two thirds of the quantity of each block chain link point device in the block chain network, and the block chain network is composed of an information management device, a first block chain link point device, a second block chain link point device and a third block chain node device, when the information management device receives the condition that the verification result of the first block chain link point device on the first testament information is successful, the verification result of the second block chain link point device on the first testament information is successful, and the verification result of the third block chain link point device on the first testament information is failed, except the information management device, of the three blockchain link point devices in the blockchain network, two blockchain link point devices successfully verify the first will information, the information management device determines that the block chain network successfully verifies the first will information, and the information management device generates a second block according to the first will information.
In one implementation, when the information management apparatus determines that the blockchain network successfully verifies the first will information, the information management apparatus may generate a digital signature of the first will information. The generation process of the digital signature of the first will-order information may be that the information management device calculates a first hash value of the first will-order information through a hash algorithm, and the information management device performs signature processing on the first hash value of the first will-order information according to a private key of the information management device to obtain the digital signature of the first will-order information, where the digital signature of the first will-order information is obtained. The information management apparatus may generate the second block from the first will information and a digital signature of the first will information.
Through the mode, the first will information is verified through the information management device and each block chain node device in the block chain network, so that the reliability of the first will information is higher, meanwhile, in the form of the block, the information management device can pack the received and unpacked will information into one block, the block at least comprises one piece of the will information, and the issuing efficiency of the will information is improved.
Step S304: the information management device issues the second block to each block link node device in the block chain network.
Specifically, the information management device may send the second block to each block link node device in the block chain network. Accordingly, each of the plurality of blockchain link point devices in the blockchain network may store the second block after receiving the second block. After successfully storing the second block, each block link point device in the block chain network can send a testimony information successful storage response to the information management device, and after receiving the testimony information successful storage response sent by each block link point device in the block chain network, the information management device indicates that the second block is successfully stored in each block link point device in the block chain network, and further indicates that the first testimony information is successfully distributed to the block chain network to which the first block link point device belongs.
In one implementation, after the information management device issues the second tile to the tile chain network to which the first tile link point device belongs, the information management device may send a persistence notification for the second tile to each tile link point device in the tile chain network. Wherein the persistence notification is to notify each block-node device to persist the second block locally at each block-node device. And under the condition that each block chain node point device of the block chain network persists the second block corresponding to the first will information, indicating that the first will information is successfully distributed to the block chain network to which the first block chain node point device belongs.
In one implementation, each of the block-chain node devices in the block-chain network locally persists the second block after receiving the persistence notification for the second block from the information management device. For example, a first block-linked-point device may locally persist the second block after receiving a persistence notification corresponding to the first block from an information management device, a second block-linked-point device may locally persist the second block after receiving a persistence notification corresponding to the second block from an information management device, and so on. It should be noted that, in the embodiment of the present invention, the first block link node device receives the persistent notification corresponding to the second block from the information management device, indicating that the block chain network has agreed on the second block, that is, indicating that the block chain network has agreed on all the first will information included in the second block.
It should be noted that, in the case that the second block corresponding to the first will information is persisted in each block link point device of the block chain network, it indicates that the first will information is successfully issued to the block chain network to which the first block link point device belongs. By the mode, the first block chain node device locally persists the second block when receiving the persistence notification, so that the situation that the first block chain node device locally persists the second block when not receiving the persistence notification (namely, the first block chain node device persists all received information) can be avoided, and the utilization rate of the storage space of the first block chain node device is improved.
Through the mode, the information management device generates the block with the wishlist information and distributes the block to the block chain network, all block chain node devices achieve consensus, the same wishlist information is recorded on all block chain node devices, the wishlist information can not be tampered, and the wishlist information is safer. Meanwhile, the storage space utilization rate of each block chain node device in the block chain network can be improved through a testimonial advice information persistence notification mechanism.
In one implementation, after the information management device issues the second block to the block chain network, each block link point device in the block chain network may receive a first will information acquisition request, where the first will information acquisition request may be issued by a will order customer or a will order beneficiary to each block link point device in the block chain network. For example, the information management device may receive a first will information acquisition request from a will order taker, the information management device may receive a first will information acquisition request from a will order beneficiary, the first block-link point device may receive a first will information acquisition request from a will order taker, the first block-link point device may receive a first will information acquisition request from a will order beneficiary, and so on. Taking the example that the first block link point device receives the first will information acquisition request from the beneficial person of the will, the first will information acquisition request may carry a second block identifier of the second block, where the second block identifier may be a second hash value of a block header of the second block, and the second hash value of the block header may uniquely and definitely identify the second block. The first block chain node device acquires a second block corresponding to the second block identifier according to the second block identifier, wherein the second block can contain the first will information and a digital signature of the first will information, wherein the digital signature can be a digital signature generated by the information management device according to the first will information, the first block chain node device can generate the first block chain node according to a public key uniquely corresponding to a private key of the information management device, decrypting the digital signature of the first will information to obtain a third hash value, calculating by the first block chain node device through a hash algorithm to obtain a fourth hash value of the first will information, comparing the third hash value with the fourth hash value by the first block chain node device, and under the condition that the third hash value is the same as the fourth hash value, the first block chain link point device outputs the first testament information to the testament beneficiary.

The condition for generating the second will information is satisfied, and the condition may be that the identity information of the first will information is successfully verified by the second block link point device. If the first will information does not satisfy the condition for generating the second will information, the second block link node device may delete the first will information, and send a second will information generation failure notification to the information management device. Illustratively, after confirming that the received will information is not notarized, the functional department sends the notarized will information to the notarization department. The justice department receives the testimony information, after the identity information of the testimony information is verified successfully, a number-letter combination sequence NOTARY OFFICE201908140006 can be added to the testimony information to obtain testimony information, and the testimony department sends the testimony information to the function department.
