Referring to fig. 1, in an example of developing a museum cultural relic information management system based on a block chain according to the present invention, a client application mainly implements a cultural relic information management subsystem to meet the requirements of the block chain, and the cultural relic information management subsystem and the block chain subsystem interact with each other through an interface defined by a SpringMVC language. The terminal equipment executing the method calls the access interface defined by the SpringMVC language to realize the execution of the method of the invention according to the protocol of the blockchain node. Although not shown, those skilled in the art will appreciate that the blockchain subsystem implements such an interactive function through one of its blockchain nodes, and thus, the client application can access the blockchain through the blockchain node. The block chain link point can access a public block chain and a private block chain, and the block chain can adopt a Redis database to realize the organization and management of data according to the logic of the block chain, without affecting the implementation of the invention. And in the cultural relic management subsystem of the client application, each functional module can be realized, including a cultural relic information adding module, a cultural relic information inquiry module, a file information modification module and the like, and the functional modules respectively provide a user for increasing the file data corresponding to the cultural relic pictures in batches, inquiring the cultural relic information related to a certain associated code, modifying the related cultural relic data and the like. The functions of the cultural relic management subsystem realized by the client application are realized through the steps of the method. The cultural relic information subsystem and the block chain subsystem have low coupling, high cohesion and clear division of labor among all modules, and realize data interaction through a network.
Referring to fig. 2, an exemplary embodiment of a method for processing historical relic information for accessing a block chain according to the present invention includes the following steps:
step S13, matching the cultural relic picture data with the cultural relic type model in the basic type database, generating corresponding type identification codes for each cultural relic picture meeting the matching, and setting the same editing frame column for the same type of cultural relic picture:
in this step, the client application may receive a cultural relic picture newly added to its subsystem by a user, and then may be used as an optional design logic to further verify the validity of the picture, so as to ensure that the picture has a legal source, a legal manager, and a legal operation authority. And after the validity is verified, executing the subsequent uplink process.
The cultural relic data corresponding to the relevant cultural relic picture data needs to be accessed to the block chain protection subsystem, and the matching of the cultural relic types needs to be carried out firstly. In this step, the client application requests to obtain the cultural relic type model, and performs classification operation on the local end.
The cultural relic type models are generally provided in advance by the invention and are generally described in a data manner, in an easy implementation example, the client application compares certain cultural relic picture data with the data of the cultural relic type models, and confirms whether the former belongs to the type referred by the latter by comparing whether the former falls into the value range corresponding to the latter. Whether the single cultural relic picture or the massive cultural relic picture can be matched and identified in such a way. Of course, the algorithm for matching the image and the model is well known in the art, and those skilled in the art should know that the algorithm is not detailed.
The process of type matching is carried out in the step, and the essence of the process is a process of intelligently classifying the cultural relic pictures. More specifically, in the classification process, the client application acquires feature data of any combination of the outline, the shape, the texture and the pattern of the cultural relic picture from the cultural relic picture data, compares the feature data with the range of the corresponding item described by the cultural relic type model to realize the matching, identifies the type of the cultural relic, generates a type identification code, and can clearly know the type and the identification rule corresponding to the cultural relic and the corresponding feature data playing a role in identifying and matching through the identification code.
As mentioned above, the type identification code includes the type information to which the cultural relic belongs, the identification rule for instructing to perform identification, and the corresponding feature data for performing identification and matching, so in an embodiment, the type identification code is suitable for the client application to search the corresponding feature data from the newly added cultural relic picture according to the identification rule, and to classify the newly added cultural relic picture matching the corresponding feature data into the type indicated by the type information. The cultural relic information adding module can utilize the function of the type identification code, and can realize the classification of the newly added cultural relic picture by adopting the information contained in the type identification code when the type of the individual cultural relic picture is identified subsequently.
In order to facilitate user editing, different editing frame bars are provided for different categories on a user interface of a client application according to the result of intelligent classification of the batch of cultural relic pictures, and the same editing frame bar is used for corresponding to the category to which the identification code of the same type belongs and is used for providing the position for editing the corresponding cultural relic data for the category. Therefore, the user can edit and input the cultural relic information through the frame bar.
Step S14, obtaining the basic data of the cultural relics of the corresponding type from the block link point according to the type identification code, and displaying the basic data of the cultural relics corresponding to each type in the corresponding editing frame column for editing to form corresponding cultural relic data:
and editing the historical relic data of the classified category of the previous step by the user is realized by combining with the automatic definition function of the client application.
The client application requests the access of the block chain protection subsystem from the block chain link point through the SpringMVC interface, after the access right is verified and the permission feedback is received, the block chain node can acquire corresponding cultural relic basic data from the block chain subsystem according to the type identification codes, the cultural relic basic data are correspondingly and pre-established for each type identification code, and can be stored in the block chain or a custom database of the block chain node and serve as basic description of corresponding types to be provided for the client application to be displayed, so that a user can further edit on the basis.
After the client application receives the basic data of the cultural relics, the corresponding editing frame columns of the basic data of the cultural relics can be identified according to the corresponding relation between each editing frame column and the category identification codes, and the basic data of the cultural relics are automatically input and displayed into the corresponding editing frame columns for the users to edit.
And after detecting a request for continuing inputting, the client application sends the request to the block chain node, the block chain node acquires the current validity of the modification authority under the identity authority of the user again, feeds back the validity result of the request to the operation end, and receives a modification instruction aiming at the basic data of the cultural relic and continuously receives the input information if the validity is met. Data formed by editing by a user on the basis of the basic data of the cultural relics are called cultural relic data, and the cultural relic data are submitted to the block chain nodes in the subsequent steps and uploaded to the block chain.
Step S15, submitting various types of cultural relic data in the editing frame bars to the block link points in response to a user instruction, so as to upload the various types of cultural relic data as the latest version to the block chain through the block link points:
as described above, the client application accepts the user's editing of the cultural relic data when the strict authority verification passes, and at the same time, the client application continuously detects whether the user triggers a user instruction for uploading the cultural relic data, and when the client application detects that the user triggers such a user instruction, the client application sends a corresponding upload request to the block link node.
After the block chain node detects that a user starts an uploading request of the cultural relic data, the validity of the cultural relic model data can be further confirmed according to the requirement of authority management, the cultural relic data uploaded by the user is accepted after the validity is met, and the block chain node links the cultural relic data for protection according to the realization of the block chain, so that the cultural relic data becomes the cultural relic data of the latest version of the cultural relic of a certain category.
In one embodiment, the historical relic basic data called in step S14 may also be the latest version or any version of historical relic data existing on the blockchain, that is, the historical relic data on the blockchain of the same historical relic category may exist in multiple edited versions, any version may be called to modify the historical relic data, and then the modified historical relic data is linked again to become the latest version of the historical relic data. Therefore, it can be understood that for the same category, modification and editing conditions of related cultural relic information can be presented theoretically through a plurality of versions of cultural relic data on the block chain, and the cultural relic information is protected in this way, so that the system is complete.
Step S16, acquiring the association code associated with the historical version of the historical relic data returned after the block link point performs the uplink operation, and completing the relic information processing, so that the client application can acquire any version of the historical relic data by using the association code:
in order to access historical cultural relic data through the client application conveniently to obtain more comprehensive cultural relic information, after all the cultural relic information is uploaded, the block link points respond to the confirmation instruction by receiving the confirmation instruction, perform internal data association operation on the cultural relic information, namely establish the association relationship between the historical cultural relic data of the new and old versions, generate a uniform association code and a key, and feed back the association code and the key to the client application. The block chain implements the association between the historical data of each version of the same type, and can be realized by a person skilled in the art by using a conventional technical means, for example, the information of each block where the historical data of each version is respectively located can be combined into the association code according to a certain rule, and then the association code is reversely analyzed. The key is not necessary in one embodiment, and the encryption mode may be various depending on the security requirement of the cultural relic management, for example, a symmetric key may be used, the association code is encrypted by using the symmetric key, the association code provided to the client application is an encrypted ciphertext, and the association code must be restored by using the key, so that the relationship between the association code and the symmetric key substantially functions as a token.
For the block chain node, for the case that the key exists, when the client application needs to execute the query through the association code, in response to the association code provided by the client application, the content of some cultural relic data and the association operation thereof which are done at a certain time on a certain day can be queried for the client application, but only the response of the block chain node can be obtained through the key for querying, and the block chain node obtains the plaintext association code through decryption by the key according to the key and the association code submitted by the user at the client application, namely, the query can be executed for the block chain node and a corresponding result can be returned.
Obviously, if the key is not needed to participate, when the client application and the block chain node interact by using the association code, the decryption link does not need to be considered, and the block chain node directly adopts the plaintext association code to perform query and feed back the corresponding result.
And on the client application side, after obtaining the key, the user can install the key into a specific USB flash disk end, so that when the query needs to be executed, the client application can firstly read the key from the USB flash disk and transmit the key and the associated code correspondingly specified by the user operation to the blockchain node so as to realize the query, so that the client application can obtain the cultural relic data of any version through the associated code.
On the basis of the implementation of the above exemplary embodiment, in a further embodiment, local utilization of the association code and the type identification code at the client application can be implemented, so that a user can query and identify the cultural relic information for a newly added cultural relic picture at a terminal device where the client application is located. Specifically, a user introduces a cultural relic picture to be identified in a client application and requests to identify the cultural relic picture; the client application responds to a request for identifying the newly added cultural relic picture, identifies the newly added cultural relic picture according to each type identification code which is generated locally before according to an identification rule in a certain type identification code, compares whether the newly added cultural relic picture has corresponding characteristic data in the type identification code, and judges that the newly added cultural relic picture is the file type represented by the type information of the type identification code when the newly added cultural relic picture has the corresponding characteristic data. Further, if the new cultural relic picture belongs to one type identification code, the client application judges that the new cultural relic picture belongs to the same type of the type identification code, then the block chain node is requested to acquire the cultural relic data of the last version corresponding to the association code related to the type identification code from the block chain, and the cultural relic data corresponding to the type identification code is further screened out from the cultural relic data correspondingly returned from the block chain link point by the client application and displayed on a user interface of the client application, so that the user can obtain the cultural relic data corresponding to the new cultural relic picture, and the purpose of inquiring the cultural relic information according to the cultural relic picture is achieved.
In addition, the cultural relic management system can regularly carry out shared program development logic in the system on the association codes, and related functions are realized in the client application, so that in a certain embodiment, the client application of the terminal equipment which obtains the association codes submits the association codes to a remote server planned by the cultural relic management system, the remote server uniformly stores the association codes to a related database, and all or part of the association codes can be pushed to other terminal equipment which is provided with the same client terminal application in various known modes, so that the same application of other terminal equipment updates a local database for storing the association codes, the association codes are shared, and the problem that different client applications can timely and efficiently share cultural relic data information is solved.
In another embodiment of the present invention, in order to enhance the user right management, the method further includes the following steps preceded by step S13 on the basis of the exemplary embodiment:
step S11, the client application of the terminal device completes user validity verification to generate a corresponding verification identification code representing the user identity, and requests the block link point to check the validity of the verification identification code:
according to the requirement of management logic, the cultural relic management system can plan two types of user identities, one is a public account number and belongs to a common user; one is a worker account which belongs to the management user, and the client application realized by the cultural relic management system allows the two types of users to log in so as to adapt to different users to open different service functions.
The client application firstly utilizes a user account system constructed by the cultural relic management system to authenticate the identity of the login user, generates a corresponding unique authentication identification code for the user after authentication is completed, and can access the blockchain node through the SpringMVC interface.
According to the program design logic and the verification identification code, the block link point can clearly know the login purpose, the login identity and the login ID of the login account, the block link point can check the user identity based on the verification identification code, and when the verification identification code is a legal identification code, the client application can access the block link subsystem through the block link point and establish subsequent butt joint with the block link point.
Specifically, the block link point performs first-step verification on the login data of the client user, feeds back a verification result, and checks the validity of the verification identification code. In order to realize such verification, when a program is developed, a coding rule of a verification identification code is generally predefined so as to obtain a login purpose, a login identity and the like according to the coding rule, an authority ID device number is stored in advance, when a new device is ready to login, an identity management U disk access is required, an ID plug-in for managing the identity in the U disk is read, and the access of the new device ID is authorized through the plug-in.
Although this embodiment discloses some examples of performing validity verification on the user login process, those skilled in the art may understand that, in order to implement strict information control, various adaptive modifications may be made on the basis of this embodiment, and details are not repeated.
Step S12, the client obtains the management authority of the user after the verification of the verification identifier is legal, and requests the block link point to check the validity of each specific authority to obtain an executable control corresponding to the legal specific authority, so that the user can perform the interaction required by the subsequent steps according to the executable controls:
in order to further enhance information security, the file management system generally configures an identity role for a user, and different roles are endowed with different management authorities, so that after the client application finishes user login, account information of a user who performs login operation can be acquired, related management authorities set by the user are extracted, and node verification is further performed for each specific management authority.
The client application may generate an authentication request for each specific management permission, include the acquired permission information of the user in the authentication request, and submit the permission information to the blockchain node.
After receiving the request, the blockchain node verifies one by one according to the corresponding specific identity user management authority data in the database of the blockchain node so as to clear the authority which has passed through the management time limit or new authority limited or added by a higher layer of management authority and determine the final management authority of the identity. Finally, under the interaction of the client application and the configuration of the block chain nodes, responding to the management request of the user, corresponding to each legal specific management authority of the user, the client application calls the management columns meeting the specific management authority, each executable control corresponding to the specific management authority of the management columns in the user authority range is started, and the user can execute the operation of the subsequent steps through each executable control. The request data and the authority change data generated in the process can be recorded into the block link points by the block link points and accessed into the database of the block link nodes so as to realize data synchronization.
It is understood that after steps S11 and S12 are completed, the subsequent steps S13 to S16 can be performed in a more secure environment.
In an improved embodiment, any historical relic information of the same historical relic is associated with the association code (for example, organized by a way of a block chain Merkle tree structure by a person skilled in the art), so that, after key verification is successful and identity authority is allowed, a data storage address is obtained through the association code (the association code represents a hash value in the Merkle tree structure and is used for pointing to a transmission address of the historical relic data distributed and stored according to the distributed storage system, and the storage address can be accessed through the hash value to obtain the corresponding historical relic data) through the association code, and then any historical relic data of the historical relic is extracted or modified through the client application. The whole operation process can upload the operation data generated in the middle to the database of the blockchain node. The database of the blockchain node stores daily operational change data. The database is recommended to adopt redis, is a key-value storage system, is similar to Memcached, supports relatively more stored value types, comprises string (character string), list (linked list), set (set), zset (sorted set-ordered set) and hash (hash type), greatly compensates the deficiency of key/value storage of Memcached and the like, and can play a good role in supplementing a relational database in partial occasions.
In a further improved embodiment, after the step S15 submits the historical relic data to the block link point, the block link point may access the corresponding historical relic data into different block chains according to different historical relic data, and thus, the client application may drive the block link point to upload the submitted historical relic data to a public block chain suitable for a general user to access or a private block chain suitable for a management user to access according to different historical relic data, so as to implement partition management.
The cultural relic data in the node database is synchronized to other clients and operation terminals applying the cultural relic management system, and specifically, preset data model matching is performed according to the cultural relic data submitted by the clients, correspondingly, the cultural relic data of a common user can be matched to a common user data model, and the cultural relic data of a management user can be matched to a management user data model, so that the cultural relic data can be automatically defined by the block chain nodes to be respectively defined as private information and public information, and then the private block chain and the public block chain are respectively accessed.
Private information can be prevented from being leaked through the public block chain, the block chain protection subsystem is accessed through the spring MVC interface according to the identity verification result, and public cultural relic information extracted from the block chain protection subsystem through the public block chain is transmitted to the local end for displaying.
The private block chain can ensure that public information and private information are not mixed, the private information can be displayed only by an account with related management authority and is not displayed for the public, so that the establishment of the private block chain also ensures the private information, and if the private information needs to be accessed, the security of the private chain is ensured by mutual authorization verification among the chain link points of the private block.
The user can check whether the local cultural relic information data is consistent with the block chain data protection subsystem or not by checking the current information, the historical revision version information record and the like of the cultural relic information in the block chain data protection subsystem through the private block chain.
In a further embodiment, the present invention provides a terminal device, which includes a central processing unit and a memory, wherein the central processing unit is configured to invoke and run a computer program stored in the memory to perform the steps of the cultural relic information processing method for accessing the block chain according to the foregoing embodiments.
In summary, the invention realizes the processing and safety control before accessing the cultural relic information of the cultural relic picture into the block chain, and is particularly suitable for application scenes such as museum cultural relic management systems.
