Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is an application environment diagram of a method for acquiring product attribute information based on a blockchain in an embodiment. (example: referring to fig. 1, the method for acquiring the work attribute information based on the blockchain is applied to an electronic evidence acquisition system, the electronic evidence acquisition system comprises a terminal 110 and a server 120, the terminal 110 and the server 120 are connected through a network, the terminal 110 can be specifically a desktop terminal or a mobile terminal, the mobile terminal can be specifically at least one of a mobile phone, a tablet computer, a notebook computer and the like, and the server 120 can be realized by an independent server or a server cluster consisting of a plurality of servers.)
As shown in fig. 2, in one embodiment, a method for acquiring work attribute information based on a blockchain is provided. The embodiment is mainly illustrated by applying the method to the server 120 in fig. 1. Referring to fig. 2, the method for acquiring the attribute information of the work based on the block chain specifically includes the following steps:
s202, obtaining a corresponding query characteristic value of the work to be queried.
The works to be inquired are the works corresponding to the information of the attribute information of the works to be inquired, such as the names, the types and the completion time of the works, and the works to be inquired in different types have different forms, such as the works in the types of characters, dictations, music, drama, music art, graphs, photography, movies and models, and have corresponding forms. The query characteristic value of the work to be queried is data suitable for being processed by the block chain after the information of the work is subjected to mapping processing. In specific implementation, a mapping algorithm, such as a hash algorithm, may be used to perform an operation on information of a work to be queried, such as content of the work to be queried or content of a work registration certificate, so as to obtain a query feature value of the work to be queried. The data obtained through the budget of the hash algorithm is data consisting of 0 and 1, the hash algorithm can map any input information or source file of the file into a unique value with a fixed length for output, and once the source file is modified and changed, the corresponding hash value is changed greatly. And the Hash operation is an irreversible process, namely, the source file cannot be calculated through the Hash value obtained by the Hash operation, so that the safety of the source file can be ensured.
S204, based on the block chain network, performing work verification on the corresponding query characteristic value of the work to be queried to obtain a work verification result; and all nodes in the block chain network carry out consensus processing on the query characteristic values of all works based on a consensus mechanism in advance.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.
The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.
The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business. The application service layer provides the application service based on the block chain scheme for the business participants to use.
The block chain network is composed of distributed nodes, each node equally stores all data, namely, the nodes realize consensus, the consensus refers to a process that multiple nodes interact to achieve agreement on certain data, behaviors or processes under a preset rule, and the consensus mechanism refers to an algorithm, a protocol and a rule defining a consensus processing process. And (3) carrying out consensus processing on the certificate-storing characteristic value of each work by each node in the blockchain network in advance based on a consensus mechanism, for example, carrying out certificate storage on each work to store evidence based on the certificate-storing characteristic value of the work obtained by a Hash algorithm, ensuring that data in the blockchain network cannot be falsified, and further effectively verifying the work by using the blockchain network.
Specifically, after the query characteristic value corresponding to the work to be queried is obtained, the work is verified according to the query characteristic value of the work to be queried based on the blockchain network, and if the query characteristic value of the work to be queried can be compared with the certificate-storing characteristic value of the certified work in the blockchain network, whether the work to be queried has the certificate or not is verified, so that a work verification result is obtained. If the information of the work to be queried, such as the content of the work to be queried or the certificate content of the work registration certificate corresponding to the work to be queried, is pre-certified in the block chain, that is, the certified characteristic value of the work to be queried is identified by each node in the block chain network, when the work is verified on the query characteristic value of the work to be queried, the block corresponding to the query characteristic value of the work to be queried can be matched from the block chain network, that is, the certified characteristic value identical to the query characteristic value of the work to be queried, and the obtained work verification result is a verification pass. Otherwise, the verification result of the work is that the verification is not passed, that is, the work to be queried is not certified in the blockchain network, and the content of the work to be queried may be tampered, so that the query characteristic value of the work to be queried is unsuccessfully matched in the blockchain network.
And S206, when the product verification result is verification passing, acquiring the product attribute information of the product to be inquired from the nodes of the block chain network.
After the product verification result of the work to be queried is obtained, if the verification is passed, the verification shows that the work to be queried has been stored in the blockchain network in advance, namely the electronic evidence has been stored in the blockchain network in advance, the product attribute information of the work to be queried can be further obtained from the nodes of the blockchain network. The work attribute information may be information related to the work, such as a work name, a work category, a work completion time, a work uplink time, a work registration time, work author information, a work registration number, or work publishing platform information. The attribute information of the work can be determined according to the type of the query characteristic value, if the query characteristic value comprises the work characteristic value of the work to be queried, the work characteristic value is obtained by mapping the work to be queried by utilizing a Hash algorithm, and the work attribute information is obtained by querying and is information related to the work; and if the query characteristic value comprises the certificate characteristic value of the work registration certificate corresponding to the work to be queried, the certificate characteristic value is obtained after the work registration certificate of the work to be queried is subjected to mapping processing through a Hash algorithm, and the work attribute information is obtained by querying and is information related to the work registration certificate.
The product attribute information may be obtained from a node of the blockchain network after the verification passes. In specific implementation, when the registration certificate of each work or the work corresponding to each work is sent to each node of the blockchain network for consensus processing, the block chain nodes locally store the work attribute information of each work, so that when the work verification result is that verification passes, the terminal can obtain the corresponding work attribute information from the nodes. Further, each node in the blockchain network may store the work attribute information of different works, for example, the node storage may be divided according to the work category to save the storage resource of each node, and each node may check the work attribute information in the local cache periodically to confirm that the work attribute information of each work stored in the local cache is not tampered. Since the works cannot be tampered after the certificates are stored in the blockchain network, the blockchain network is utilized to verify the works of the corresponding query characteristic values of the works to be queried, and after the verification is passed, the corresponding work attribute information is obtained from the nodes of the blockchain network, so that the authenticity of the work attribute information can be obtained.
According to the work attribute information acquisition method based on the block chain, work verification is carried out on the corresponding query characteristic value of the work to be queried through the block chain network after the query characteristic value of each work is subjected to consensus processing on each node based on the consensus mechanism in advance, the work attribute information of the work to be queried is acquired from the nodes of the block chain network after the verification is passed, the characteristic that data in the block chain network cannot be tampered is fully utilized, and the authenticity of the acquired work attribute information is ensured.
In one embodiment, based on a block chain network, performing a work verification on a query feature value corresponding to a work to be queried, and obtaining a work verification result includes: sending the query characteristic value to a node of a block chain network, wherein the query characteristic value is used for indicating the node to query a corresponding certificate-storing characteristic value of the work to be queried; obtaining a query result obtained by query; and obtaining a work checking result according to the query result.
In this embodiment, each node in the blockchain network performs consensus processing on the query characteristic value of each work in advance based on a consensus mechanism, that is, each node in the blockchain network performs evidence storage on information of each work in advance, the evidence storage characteristic value of each work is stored, whether the information of the work to be queried has been pre-verified in the blockchain network can be determined through characteristic value query, thereby verifying the work of the work to be queried and obtaining a work verification result.
Specifically, when the query characteristic value of the work to be queried is subjected to work verification, the query characteristic value of the work to be queried is sent to a node of the blockchain network, and the query characteristic value can be sent to any node in the blockchain network, where the certificate-storing characteristic value of each work is stored, so as to indicate the node to query the certificate-storing characteristic value corresponding to the work to be queried, where the certificate-storing characteristic value is information of the work to be queried, such as a feature value corresponding to the information of the work to be queried when the content of the work to be queried or a work registration certificate waits for the certificate-storing of the information of the work to be queried in the blockchain network. The nodes of the block chain network can store the certificate storage characteristic values of all the commonly recognized works, and whether the information of the works to be inquired is pre-certified or not can be determined according to the existence of the certificate storage characteristic values corresponding to the characteristic values of the works to be inquired. And acquiring a query result obtained by query, if the query determines that the certificate-storing characteristic value corresponding to the characteristic value of the work to be queried exists, namely the certificate-storing characteristic value is successfully queried, otherwise, the query fails. Obtaining a work verification result according to the query result, if the evidence storing characteristic value which is the same as the query characteristic value of the work to be queried is queried, the information of the work to be queried is proved to be stored in the block chain network in advance, the query characteristic value of the work to be queried is the same as the evidence storing characteristic value, the content of the current work to be queried or the work registration book corresponding to the work to be queried is completely the same as the content of the evidence storing, and the work verification result can be passed if the content is not tampered; otherwise, the verification is not passed, that is, the information of the work to be queried is not stored in advance, or the information of the current work to be queried is tampered, so that the query characteristic value of the work to be queried cannot be matched with the certificate storage characteristic value of the work during certificate storage.

Specifically, when the query feature value includes a work feature value of the work to be queried, it indicates that information corresponding to the work to be queried itself needs to be queried, and the obtained work attribute information of the work to be queried includes at least one item of a work name, a work category, work completion time, work uplink time, work author information, and work publishing platform information.
The name of the work is the name of the work to be inquired, such as the name of a musical work, the name of the work, the name of a drama and the like; the product category is the classification category of the product to be inquired, such as different form categories of characters, dictations, music, drama or dance and the like; the work completion time is the creation or manufacturing completion time of the work to be inquired, and the work completion time can be determined according to the evidence storage time of the work information during specific implementation; the uplink time of the work can be the time for uploading the information of the work to the block chain for evidence storage; the work author information is related information of an author corresponding to the work to be inquired, such as author name, contact information, identity card number and the like; the information in the work publishing platform may be platform information for publishing the work to be queried for the first time, or may be all platform information for publishing the work to be queried, such as a public number, a blog and the like. In specific application, the work attribute information can be flexibly set according to actual requirements.
In one embodiment, when the query feature value includes a certificate feature value of a work registration certificate corresponding to the work to be queried, the obtained work attribute information of the work to be queried includes at least one of a work name, a work category, work completion time, work uplink time, work registration time, work author information, a work registration number, and work publishing platform information.
In this embodiment, the query feature value includes a certificate feature value of a work registration certificate corresponding to the work to be queried, and the certificate feature value is obtained by mapping the work registration certificate of the work to be queried by using a hash algorithm, so that the corresponding work attribute information may be information related to the work registration certificate corresponding to the work to be queried. Specifically, when the query feature value includes a certificate feature value of a work registration certificate corresponding to the work to be queried, the obtained work attribute information includes at least one of a work name, a work category, work completion time, work uplink time, work registration time, work author information, a work registration number, and work publishing platform information. The work registration time can be the time for registering the work to be inquired; the work registration number may be a number to be managed after registration for the inquiry work, for identifying and managing the registered work. In specific application, the work attribute information can be flexibly set according to actual requirements.
In an embodiment, as shown in fig. 3, after obtaining the work attribute information of the work to be queried, the method further includes a step of performing structured processing on the work attribute information, which specifically includes:
s302, inquiring a preset attribute information template base.
In this embodiment, the obtained work attribute information is subjected to structured processing by using a preset attribute information template to obtain structured work attribute information, so that the work attribute information is efficiently managed, controlled and visually displayed. Specifically, after the product attribute information of the product to be queried is obtained, a preset attribute information template library is queried. The attribute information template library stores various structured attribute information templates, such as various chart templates, in advance. The attribute information template may be preset according to specific service requirements, for example, setting statistical items of the work attribute information, data display order, and the like.
S304, obtaining a structured attribute information template corresponding to the product attribute information of the product to be inquired from the attribute information template library.
The structured attribute information template corresponds to various product attribute information so as to carry out structured processing on the product attribute information. In specific implementation, the corresponding structured attribute information template can be queried from the attribute information template library according to the information type in the product attribute information of the product to be queried. For example, when the information type of the attribute information of the work includes author information of the work, a structured attribute information template of the author information, specifically, a template of an author brief introduction, may be obtained from the attribute information template library.
S306, updating the attribute information template according to the work attribute information of the work to be inquired to obtain the structured work attribute information.
After the structured attribute information template corresponding to the work attribute information of the work to be queried is obtained, the attribute information template is updated based on the work attribute information of the work to be queried, and specifically, the work attribute information can be directly filled in the attribute information template, or the work attribute information is filled in the attribute information template after certain processing is performed, such as word number statistics and chapter statistics of the written works, so that the structured work attribute information is obtained. The structured work attribute information divides and counts the work attribute information, so that the work attribute information can be managed conveniently, and the related information of the work to be inquired can be displayed more visually.
In one embodiment, further comprising: storing the work attribute information into a cache; when the duration of the work attribute information in the cache reaches the survival duration corresponding to the work attribute information, deleting the work attribute information from the cache; wherein the survival time duration is a fixed time duration or a time duration dynamically determined according to the query record of the work attribute information.
In this embodiment, the obtained work attribute information is stored and maintained through a preset cache, so that the corresponding work attribute information can be quickly obtained in the next query. In addition, the attribute information of the works stored in the cache is monitored to judge whether the attribute information of the works is maintained continuously or not, so that cache resources are effectively utilized.
Specifically, after the attribute information of the work is obtained, the attribute information of the work is stored in a cache, for example, a local memory. And monitoring the attribute information of the works stored in the cache to judge whether to maintain the attribute information of the works. If the survival time of each piece of work attribute information in the cache is monitored, and the time length of the piece of work attribute information in the cache reaches the survival time length corresponding to the piece of work attribute information, which indicates that the piece of work attribute information can be maintained, the piece of work attribute information is deleted from the cache, so that the space of the cache is released.
The survival time corresponding to the work attribute information can be a preset fixed time, such as 15 days or 1 month, namely, the work attribute information in the cache is maintained for 15 days or 1 month, and if the work attribute information is stored to 15 days or 1 month after the cache, if the corresponding query characteristic value for the work to be queried is received again, namely the work attribute information of the work to be queried needs to be queried, the query characteristic value can be directly obtained from the cache, thereby avoiding revising the block chain network and effectively improving the query processing efficiency. If the query is not triggered again within 15 days or 1 month, the work attribute information is deleted from the cache, the cache space is released, and the cache resources are saved. The survival time may also be a time dynamically determined for the query record according to the work attribute information, for example, for a work to be queried with a high query frequency, the survival time of the corresponding work attribute information may be longer, such as 1 month or 15 days; for the works to be queried with lower query frequency, the survival time of the corresponding work attribute information may be shorter, such as 10 days or 7 days. At this time, the survival time duration can be dynamically updated according to the query record of the attribute information of the work, that is, the query frequency of the work is determined according to the query record of the attribute information of the work, and then the corresponding survival time duration is updated based on the query frequency, so that the cached storage resource is fully utilized.
In one embodiment, before performing a work verification on a query feature value corresponding to a work to be queried based on a blockchain network to obtain a work verification result, the method further includes: when a work certificate storing request is received, acquiring data to be certified and attribute information corresponding to the data to be certified, which correspond to the work certificate storing request; acquiring a certificate storage mode corresponding to the data type of the data to be stored; determining a characteristic value of data to be stored according to a storage mode; and sending the attribute information and the characteristic value of the data to be stored into the nodes of the block chain network for data storage.
In this embodiment, the feature value of each work and the attribute information of each work, or the feature value of the work registration certificate corresponding to each work and the attribute information of the work registration certificate are stored in the blockchain network in advance, and the attribute information and the feature value of the data to be stored are stored according to the storage mode corresponding to the data type of the data to be stored. And after the verification of the query characteristic value is passed, returning attribute information corresponding to the certified data to be certified, wherein the attribute information is used as the work attribute information of the work to be queried.
Specifically, when a work certificate storing request for requesting certificate storing processing of a work or a work registration certificate is received, data to be certified corresponding to the work certificate storing request and attribute information corresponding to the data to be certified are obtained, and the data to be certified may include the work or the work registration certificate. The attribute information corresponding to the data to be credited can be the work attribute information of the work, such as the work name, the work category, the work completion time, the work chain linking time, the work author information or the work publishing platform information; the attribute information corresponding to the data to be certified may also be certificate attribute information of a work registration certificate, such as a work name, a work category, work completion time, work uplink time, work registration time, work author information, a work registration number, or work publishing platform information. The work evidence storing request may include an obtaining path of the data to be stored, such as a link address, so as to obtain the data to be stored, such as various works, such as characters, dictation, music, drama, music art, figures or models, etc., or work registration certificates, which are required to be stored correspondingly according to the work evidence storing request.

In specific application, certificate storage triggering conditions can be set, the certificate storage triggering conditions can be set based on the data types of the data to be subjected to certificate storage, for example, for works of character types, different certificate storage triggering conditions can be set for the structural relations of all chapters, so that after the works are split, the certificate storage can be respectively carried out on the contents of all parts of the works; for example, for a work registration certificate, the certificate can be stored when the integrity of certificate storage information is met. On one hand, after receiving the characteristic value of the data to be stored, the node of the block chain network performs local storage on the characteristic value of the data to be stored, and performs consensus processing on the characteristic value of the data to be stored in the block chain network based on a consensus mechanism; on the other hand, after receiving the attribute information, the node stores the attribute information into a local cache, so that the characteristic value of the data to be stored is stored in each node of the blockchain network, the attribute information is stored, the storage of the data to be stored in the blockchain network is realized, and the corresponding work attribute information can be returned after the verification of the query characteristic value is passed.
In one embodiment, sending the attribute information and the characteristic value of the data to be stored to a node of the blockchain network for data storage includes: acquiring a certificate storage triggering condition corresponding to the characteristic value of the data to be stored; and when the evidence storage triggering condition is met, the attribute information and the characteristic value of the data to be stored are sent to the nodes in the block chain network for data storage.
In this embodiment, the sending of the attribute information and the characteristic value of the data to be stored is controlled by the set certificate storage triggering condition, so that the certificate storage control of the data to be stored and the attribute information is realized. Specifically, the certificate storing triggering conditions corresponding to the characteristic values of the data to be stored with certificates are obtained, the certificate storing triggering conditions can be correspondingly set according to the division of the works or the integrity requirement conditions of the registration certificates of the works, and specifically include triggering conditions such as triggering time and triggering actions. And after obtaining the evidence storing triggering condition corresponding to the characteristic value of the data to be stored, monitoring whether the evidence storing triggering condition is met, if so, sending the attribute information and the characteristic value of the data to be stored into the node of the block chain network for storing the evidence, and thus, realizing the uplink processing of the data to be stored. During specific implementation, for the characteristic value of the data to be stored, which is sent to a node in the block chain network, the node performs local storage on the characteristic value of the data to be stored, and performs consensus processing in the belonging block chain based on a consensus mechanism after the local storage; for the attribute information, the node stores the attribute information into a preset cache so as to store the attribute information, and returns corresponding data to be stored as the work attribute information of the work to be inquired after the inquiry characteristic value passes the verification.
