Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
FIG. 1 is an application environment diagram of a blockchain-based work attribute information acquisition method in one embodiment. ( Examples: referring to fig. 1, the blockchain-based work attribute information acquisition method is applied to an electronic evidence acquisition system. The electronic proof acquisition system includes a terminal 110 and a server 120. The terminal 110 and the server 120 are connected through a network. The terminal 110 may be a desktop terminal or a mobile terminal, and the mobile terminal may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The server 120 may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers. )
As shown in FIG. 2, in one embodiment, a blockchain-based work attribute information acquisition method is provided. The present embodiment is mainly exemplified by the application of the method to the server 120 in fig. 1. Referring to fig. 2, the blockchain-based work attribute information acquisition method specifically includes the steps of:
s202, acquiring a corresponding query characteristic value of the work to be queried.
The works to be queried are works corresponding to information such as names, types and completion time of works to be queried, and different types of works to be queried have different forms, such as works of the types of characters, dictations, music, drama, folk art forms (including ballad singing, story telling, comic dialogues, clapper talks, cross talks, etc.), graphics, photography, films, videos, models and the like, and have corresponding works forms. The query characteristic value of the work to be queried is data which is suitable for being processed by a block chain after mapping the information of the work. In specific implementation, the mapping algorithm, such as a hash algorithm, can be used for calculating the information of the work to be queried, such as the content of the work to be queried or the content of the work registration certificate, and the like, so as to obtain the query characteristic value of the work to be queried. The data obtained through the budget of the hash algorithm is data composed 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 to output, and once the source file is subjected to any modification and change, the corresponding hash value can be greatly changed. 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, checking the works to be checked according to the corresponding inquiry characteristic values of the works to be checked to obtain work checking results; wherein, each node in the block chain network carries out consensus processing on the query characteristic value of each work in advance based on a consensus mechanism.
The blockchain 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. The blockchain (Blockchain), essentially a de-centralized database, is a string of data blocks that are generated in association using cryptographic methods, each of which contains information from a batch of network transactions for verifying the validity (anti-counterfeit) of its information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.
The blockchain underlying platform may include processing modules for user management, basic services, smart contracts, and the like. The user management module is responsible for identity information management of all blockchain participants, including maintenance of public and private key generation (account management), key management, maintenance of corresponding relation between the real identity of the user and the blockchain address (authority management) and the like, and under the condition of authorization, supervision and audit of transaction conditions of certain real identities, and provision of rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node devices, is used for verifying the validity of a service request, recording the service request on a storage after the effective request is identified, for a new service request, the basic service firstly analyzes interface adaptation and authenticates the interface adaptation, encrypts service information (identification management) through an identification algorithm, and transmits the encrypted service information to a shared account book (network communication) in a complete and consistent manner, and records and stores the service information; the intelligent contract module is responsible for the registration and release of contracts, the triggering of contracts and the execution of contracts, developers can define contract logic through a certain programming language, release the contract logic to a blockchain (contract registration), call keys or other event triggering execution according to the logic of contract clauses to complete the contract logic, and simultaneously provide the function of logging off the upgrade of the contracts.
The platform product service layer provides basic capabilities and implementation frameworks of typical applications, and developers can complete the blockchain implementation of business logic based on the basic capabilities and the characteristics of the superposition business. The application service layer provides the application service based on the block chain scheme to the business participants for use.
The block chain network is composed of distributed nodes, each node stores all data equally, namely, each node realizes consensus, wherein the consensus refers to a process that nodes participated in by multiple parties agree on certain data, behaviors or flows through interaction of multiple nodes under a preset rule, and a consensus mechanism refers to an algorithm, a protocol and a rule defining a consensus processing process. Each node in the blockchain network carries out consensus processing on the evidence storage characteristic value of each work in advance based on a consensus mechanism, for example, the evidence storage characteristic value of the work obtained based on a hash algorithm realizes the evidence storage of each work to save evidence and ensures that data in the blockchain network cannot be tampered, thereby effectively verifying the work by using the blockchain network.
Specifically, after obtaining the query characteristic value corresponding to the work to be queried, checking the query characteristic value of the work to be queried based on the blockchain network, for example, comparing the query characteristic value of the work to be queried with the evidence-preserving characteristic value of the evidence-preserving work in the blockchain network, thereby checking whether the work to be queried is in evidence-preserving state or not, and obtaining a work checking result. 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-stored in the blockchain, namely, the stored certificate characteristic value of the work to be queried is commonly recognized by each node in the blockchain network, when the query characteristic value of the work to be queried is checked, the block corresponding to the query characteristic value of the work to be queried, namely, the stored certificate characteristic value identical to the query characteristic value of the work to be queried, can be matched from the blockchain network, and then the obtained work checking result is checked. Otherwise, the work verification result indicates that the verification is not passed, that is, the work to be queried is not verified in the blockchain network, or the content of the work to be queried is possibly tampered, so that the query characteristic value of the work to be queried is not successfully matched in the blockchain network.
S206, when the product verification result is verification pass, obtaining the attribute information of the product to be queried from the nodes of the block chain network.
After the work verification result of the work to be queried is obtained, if the verification is passed, the work to be queried is shown to be pre-stored in the blockchain network, namely, the electronic evidence is pre-stored in the blockchain network, and then the work attribute information of the work to be queried can be further obtained from the nodes of the blockchain network. The attribute information of the works may be information related to the works, such as names of the works, categories of the works, completion time of the works, time of the works being wound up, registration time of the works, author information of the works, registration numbers of the works, release platform information of the works, and the like. 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 characteristic value of the work to be queried, the characteristic value of the work is obtained after mapping the work to be queried by utilizing a hash algorithm, and the attribute information of the queried work is information related to the work; and if the inquiry characteristic value comprises the certificate characteristic value of the work registration certificate corresponding to the work to be inquired, mapping the work registration certificate of the work to be inquired through a hash algorithm to obtain the certificate characteristic value, and inquiring to obtain the attribute information of the work as the information related to the work registration certificate.
The work attribute information can be obtained from nodes of the blockchain network after verification is passed. When the system is concretely implemented, when each work or each work registration certificate corresponding to each work is sent to each node of the blockchain network to carry out consensus processing, the blockchain node locally stores the work attribute information of each work, so that when the work verification result is that verification is passed, the terminal can acquire the corresponding work attribute information from the node. Further, each node in the blockchain network can store the attribute information of works of different works, for example, the nodes can be divided according to the types of the works to save the storage resources of each node, and each node can periodically check the attribute information of the works in the local cache to confirm that the attribute information of the works stored in the local cache is not tampered. And because the work cannot be tampered after being stored in the blockchain network, checking the work by utilizing the corresponding inquiry characteristic value of the work to be inquired, and acquiring the corresponding work attribute information from the nodes of the blockchain network after the checking is passed, so that the authenticity of the acquired work attribute information can be obtained.
According to the method for acquiring the attribute information of the works based on the blockchain, the blockchain network which is subjected to consensus processing on the query characteristic values of the works in advance based on the consensus mechanism performs work verification on the query characteristic values corresponding to the works to be queried, the attribute information of the works to be queried is acquired from the nodes of the blockchain network after the verification is passed, the characteristic that data in the blockchain network cannot be tampered is fully utilized, and the authenticity of the acquired attribute information of the works is ensured.
In one embodiment, based on a blockchain network, performing work verification on a query feature value corresponding to a work to be queried, and obtaining a work verification result includes: sending the inquiry characteristic value to a node of the blockchain network, wherein the inquiry characteristic value is used for indicating the node to inquire the corresponding certificate storing characteristic value of the work to be inquired; acquiring a query result obtained by query; and obtaining a work verification result according to the query result.
In this embodiment, each node in the blockchain network performs consensus processing on the query feature value of each work in advance based on a consensus mechanism, that is, each node in the blockchain network performs evidence storage on the information of each work in advance, the evidence storage feature value of each work is stored, whether the information of the work to be queried is pre-evidence stored in the blockchain network can be determined through feature value query, and work verification of the work to be queried is achieved, so that a work verification result is obtained.
Specifically, when checking the query feature value of the work to be checked, the query feature value of the work to be checked is sent to a node of the blockchain network, and when the query feature value is realized, the query feature value can be sent to any node of the blockchain network, which stores the certificate feature value of each work, so as to instruct the node to check the certificate feature value corresponding to the work to be checked, wherein the certificate feature value is the feature value corresponding to the information of the work to be checked when the content of the work to be checked or the information of the work to be checked is checked in the blockchain network. The nodes of the blockchain network can store the certification characteristic values of all the commonly-known works, and whether the information of the works to be queried is pre-certified or not can be determined according to the existence of the certification characteristic values corresponding to the characteristic values of the works to be queried. And obtaining a query result obtained by query, if the query determines that the stored certificate characteristic value corresponding to the characteristic value of the work to be queried exists, namely the stored certificate characteristic value is successfully queried, otherwise, the query fails. Obtaining a work verification result according to the query result, if the information of the work to be queried is pre-stored in the blockchain network when the storage characteristic value which is the same as the query characteristic value of the work to be queried is queried, the query characteristic value of the work to be queried is the same as the storage characteristic value, the current work to be queried or the content of the work registration book corresponding to the work to be queried is the same as that of the storage, and the obtained work verification result can be verification passing if no falsification occurs; otherwise, if the verification is not passed, the information of the work to be queried is not pre-stored, 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 storage characteristic value of the work in the storage process.
In one embodiment, when the query characteristic value includes a work characteristic value of 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, a work completion time, a work chaining time, work author information, and work distribution platform information.
In this embodiment, the query feature value includes a work feature value of the work to be queried, where the work feature value is obtained by mapping the work to be queried through a hash algorithm, and the corresponding work attribute information may be information related to the work to be queried. Specifically, when the query characteristic value includes a work characteristic value of the work to be queried, indicating that the information corresponding to the work to be queried needs to be queried, the acquired work attribute information of the work to be queried includes at least one of a work name, a work category, a work completion time, a work chaining time, work author information and work publishing platform information.
The names of the works are names of the works to be queried, such as music works, copybook names, drama names and the like; the work categories are the classification categories of works to be queried, such as different forms of categories of words, dictations, music, drama or dance, and the like; the work completion time is the creation or production completion time of the work to be queried, and can be determined according to the evidence storage time of the work information in specific implementation; the work uplink time can be the time of uploading the information of the work to the blockchain for certification; the information of the authors of the works to be queried is related information of the authors corresponding to the works to be queried, such as the name, contact information, identity card number and the like of the authors; the information in the work publishing platform can be the first-time publishing platform information of the work to be queried, and can also be all the platform information of the work to be queried which is published, such as public numbers, blogs and the like. When the method is applied specifically, the attribute information of the works can be flexibly set according to actual requirements.
In one embodiment, when the query characteristic value includes a certificate characteristic 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, a work completion time, a work chaining time, a work registration time, work author information, a work registration number, and work distribution 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, where the certificate feature value is obtained by mapping the work registration certificate of the work to be queried using a hash algorithm, and the corresponding work attribute information may be information related to the work registration certificate corresponding to the work to be queried. Specifically, when the inquiry feature value includes a certificate feature value of a work registration certificate corresponding to a work to be inquired, the obtained work attribute information includes at least one of a work name, a work category, a work completion time, a work chaining time, a work registration time, work author information, a work registration number, and work distribution platform information. The work registration time may be a time for performing registration processing on works to be queried; the work registration number may be a number managed after registration for the query work, for identifying and managing the registered work. When the method is applied specifically, the attribute information of the works can be flexibly set according to actual requirements.
In one embodiment, as shown in fig. 3, after the work attribute information of the work to be queried is acquired, the method further includes the step of structuring the work attribute information, specifically including:
S302, inquiring a preset attribute information template library.
In this embodiment, the obtained attribute information of the work is structured through a preset attribute information template, so as to obtain structured attribute information of the work, so that the attribute information of the work is efficiently managed and visually displayed. Specifically, after obtaining the attribute information of the work to be queried, querying a preset attribute information template library. The attribute information template library stores various structured attribute information templates, such as various chart templates, in advance. The attribute information template can be preset according to specific business requirements, for example, statistical items of the attribute information of works, data display sequence and the like are set.
S304, obtaining a structured attribute information template corresponding to the work attribute information of the work to be queried from the attribute information template library.
The structured attribute information template corresponds to various pieces of attribute information of the work so as to carry out structured processing on the attribute information of the work. In specific implementation, according to the information type in the attribute information of the work to be queried, the corresponding structured attribute information template can be queried from the attribute information template library. For example, when the information type of the attribute information of the work includes the information of the author of the work, a structured attribute information template of the author information, particularly a template of an author profile, may be obtained from the attribute information template library.
S306, updating the attribute information template according to the attribute information of the work to be queried to obtain structured attribute information of the work.
After the structured attribute information template corresponding to the attribute information of the work to be queried is obtained, updating the attribute information template based on the attribute information of the work to be queried, specifically, the attribute information of the work can be directly filled into the attribute information template, or the attribute information of the work can be processed to a certain extent, such as word count statistics and chapter statistics, and then is filled into the attribute information template to obtain the structured attribute information of the work. The structured work attribute information carries out division statistics on the work attribute information, so that management of the work attribute information can be facilitated, and related information of the work to be queried can be displayed more intuitively.
In one embodiment, further comprising: storing the attribute information of the works 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; the survival time length is a fixed time length or a time length dynamically determined according to the query record of the attribute information of the work.
In this embodiment, the obtained attribute information of the work is stored and maintained through a preset cache, so that the corresponding attribute information of the work can be quickly obtained when the next query is performed. In addition, the attribute information of the works stored in the cache is monitored to judge whether the attribute information of the works is continuously maintained or not, so that the cache resources are effectively utilized.
Specifically, after obtaining the attribute information of the work, the attribute information of the work is stored in a cache, for example, a memory of a local terminal. And monitoring the attribute information of the works stored in the cache to judge whether the attribute information of the works is maintained or not. If the survival time length of each piece of attribute information in the cache is monitored, when the time length of the piece of attribute information in the cache reaches the survival time length corresponding to the piece of attribute information, the piece of attribute information is indicated to be unnecessary to maintain, and the piece of 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 may be a preset fixed time, for example, 15 days or 1 month, that is, the work attribute information in the cache is maintained for 15 days or 1 month, and in 15 days or 1 month after the work attribute information is stored in the cache, if the query characteristic value corresponding to the work to be queried is received again, that is, when the work attribute information of the work to be queried needs to be queried, the work attribute information can be directly obtained from the cache, so that the re-access to the blockchain network is avoided, and the query processing efficiency is effectively improved. If the inquiry is not triggered again within 15 days or 1 month, the attribute information of the work is deleted from the cache, the cache space is released, and the cache resources are saved. The survival time length can also be dynamically determined by the time length according to the query record of the attribute information of the works, for example, for the works to be queried with high query frequency, the survival time length of the attribute information of the corresponding works can 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 attribute information of the works can be shorter, such as 10 days or 7 days. At this time, the survival time length can be dynamically updated according to the query record of the attribute information of the work, namely, the query frequency of the attribute information of the work is determined according to the query record of the attribute information of the work, and then the corresponding survival time length is updated based on the query frequency, so that the cached storage resource is fully utilized.
In one embodiment, before performing work verification on the query characteristic value corresponding to the work to be queried based on the blockchain network to obtain a work verification result, the method further comprises: when a work license request is received, obtaining to-be-stored data corresponding to the work license request and attribute information corresponding to the to-be-stored data; acquiring a certificate storing 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 to a node of the blockchain network for data storage.

After the characteristic value of the data to be stored is determined according to the storage mode, the attribute information and the characteristic value of the data to be stored are sent to nodes in the block chain network for data storage. When the method is specifically applied, a certification storage triggering condition can be set, wherein the certification storage triggering condition can be set based on the data type of the data to be certified, for example, for works with text types, different certification storage triggering conditions can be set for each chapter structural relationship so as to realize the respective certification storage of each part of the content of the works after the works are split; such as for work registration certificates, the certification may be performed when the integrity of the certificate certification information is satisfied. On the one hand, after receiving the characteristic value of the data to be stored, the node of the blockchain network carries out local storage on the characteristic value of the data to be stored, and carries out consensus processing on the characteristic value of the data to be stored in the blockchain network based on a consensus mechanism; on the other hand, the nodes store the attribute information into a local cache after receiving the attribute information, so that the characteristic values of the data to be stored are stored in each node of the blockchain network, the attribute information is stored, the blockchain network is used for storing the data to be stored, and the corresponding attribute information of the work can be returned after the verification of the query characteristic values is passed.
In one embodiment, transmitting attribute information and a characteristic value of data to be authenticated to a node of a blockchain network for data authentication includes: acquiring a certificate storing triggering condition corresponding to a characteristic value of data to be stored; and when the certification triggering condition is met, the attribute information and the characteristic value of the data to be certified are sent to nodes in the blockchain network for data certification.
In this embodiment, the sending of the attribute information and the characteristic value of the data to be stored is controlled by the set storage triggering condition, so as to realize the storage control of the data to be stored and the attribute information. Specifically, the storage triggering conditions corresponding to the feature values of the data to be stored are obtained, the storage triggering conditions can be set correspondingly according to the storage mode to divide the works or the integrity requirement conditions of the registration certificates of the works, the triggering conditions can include triggering time, triggering actions and the like, for example, the corresponding storage triggering conditions can be set for each part of content of the data to be stored respectively, and particularly, different storage triggering times are used for carrying out the storage processing on each part of content of the data to be stored respectively according to time. After obtaining the certification triggering condition corresponding to the characteristic value of the data to be certified, monitoring whether the certification triggering condition is met, if yes, sending the attribute information and the characteristic value of the data to be certified to a node of a blockchain network for certification, and thus realizing the uplink processing of the data to be certified. When the method is specifically implemented, for the characteristic value of the data to be stored, which is sent to the node in the blockchain network, the node can perform local storage of the characteristic value of the data to be stored, and perform consensus processing in the affiliated blockchain based on a consensus mechanism after the local storage; for the attribute information, the node stores the attribute information into a preset cache to save the attribute information, and returns corresponding to-be-saved data after checking the query characteristic value, and the corresponding to-be-saved data is used as the attribute information of the work to be queried.
