Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the subject matter of the present application can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the application.

The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

In the related technology of the application, the traditional electronic evidence storing method mainly adopts a single evidence storing mode depending on a centralized server, and the mode gradually shows the defects of high cost, low efficiency, difficult letter collection and the like when facing the increasing electronic data storing requirement.

In the centralized authentication mode, once the centralized server is attacked, the authentication data is easily lost or tampered. When the evidence is needed to be used, data is required to be exported from the server, so that the efficiency is influenced, the whole process lacks notarization and supervision, the reliability of the data is extremely low, and the credit collecting proportion of the evidence in litigation is directly influenced. In addition, electronic data depends on electronic medium storage, and more media are needed to be used as backup for storage safety, but the media have service life limitation, so the storage cost is high.

Electronic evidence stored under the centralized evidence storage module can be modified in a single party in the evidence obtaining process. The traditional evidence obtaining mode adopts the mobile terminal equipment or personal computer and other equipment of the user, and the party can easily delete and modify the data, so that whether the obtained evidence is real or complete is unknown, and the authenticity of the related data cannot be ensured. Therefore, there is a lack of confidence in litigation.

In the aspect of evidence identification, the electronic evidence obtained after evidence storage and evidence collection needs to be judged by 'three properties', namely evidence authenticity, validity and relevance. Because the electronic evidence has the characteristics of large data volume, strong real-time property, high preservation cost, difficult identification and the like, the identification of the three properties of the evidence is difficult, the electronic evidence acquired in a centralized mode is more difficult to identify, and the support effect on cases is required, so that great pressure is exerted on judges and parties.

In conclusion, the traditional electronic evidence storage mode based on the centralized server has great problems in the aspects of evidence storage, evidence obtaining and evidence identification, is difficult to ensure the objectivity, integrity and authenticity of the electronic evidence, and needs to be improved in the aspects of evidence storage efficiency and evidence storage reliability.

Aiming at the problems in the related art, the application provides a block chain-based network page evidence storing method which is used for carrying out evidence storing management on a network page so as to improve the usability of the network page as an electronic evidence.

The block chain-based network page evidence storing method provided by the embodiment of the application relates to a cloud technology, in particular to a file storage application or an object storage application based on a cloud computing technology, a cloud storage technology and a block chain technology.

Cloud technology refers to a hosting technology for unifying serial resources such as hardware, software, network and the like in a wide area network or a local area network to realize calculation, storage, processing and sharing of data.

Cloud technology (Cloud technology) is based on a general term of network technology, information technology, integration technology, management platform technology, application technology and the like applied in a Cloud computing business model, can form a resource pool, is used as required, and is flexible and convenient. Cloud computing technology will become an important support. Background services of the technical network system require a large amount of computing and storage resources, such as video websites, picture-like websites and more web portals. With the high development and application of the internet industry, each article may have its own identification mark and needs to be transmitted to a background system for logic processing, data in different levels are processed separately, and various industrial data need strong system background support and can only be realized through cloud computing.

Cloud computing (cloud computing) is a computing model that distributes computing tasks over a pool of resources formed by a large number of computers, enabling various application systems to obtain computing power, storage space, and information services as needed. The network that provides the resources is referred to as the "cloud". Resources in the "cloud" appear to the user as being infinitely expandable and available at any time, available on demand, expandable at any time, and paid for on-demand.

As a basic capability provider of cloud computing, a cloud computing resource pool (called as an ifas (Infrastructure as a Service) platform for short is established, and multiple types of virtual resources are deployed in the resource pool and are selectively used by external clients.

A distributed cloud storage system (hereinafter, referred to as a storage system) refers to a storage system that integrates a large number of storage devices (storage devices are also referred to as storage nodes) of different types in a network through application software or application interfaces to cooperatively work by using functions such as cluster application, grid technology, and a distributed storage file system, and provides a data storage function and a service access function to the outside.

At present, a storage method of a storage system is as follows: logical volumes are created, and when created, each logical volume is allocated physical storage space, which may be the disk composition of a certain storage device or of several storage devices. The client stores data on a certain logical volume, that is, the data is stored on a file system, the file system divides the data into a plurality of parts, each part is an object, the object not only contains the data but also contains additional information such as data identification (ID, ID entry), the file system writes each object into a physical storage space of the logical volume, and the file system records storage location information of each object, so that when the client requests to access the data, the file system can allow the client to access the data according to the storage location information of each object.

The process of allocating physical storage space for the logical volume by the storage system specifically includes: physical storage space is divided in advance into stripes according to a group of capacity measures of objects stored in a logical volume (the measures often have a large margin with respect to the capacity of the actual objects to be stored) and Redundant Array of Independent Disks (RAID), and one logical volume can be understood as one stripe, thereby allocating physical storage space to the logical volume. With the development of diversification of internet, real-time data stream and connecting equipment and the promotion of demands of search service, social network, mobile commerce, open collaboration and the like, cloud computing is rapidly developed. Different from the prior parallel distributed computing, the generation of cloud computing can promote the revolutionary change of the whole internet mode and the enterprise management mode in concept.

As shown in fig. 1, the blockchain system 100 may include at least one client 110 and a blockchain network 120, the blockchain network 120 including at least one node device 121. The client 110 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, or other electronic devices. The node device 121 may be any form of electronic device such as a terminal device or a server, for example, the node device 121 may be an independent physical server, may also be a server cluster or a distributed system formed by a plurality of physical servers, and may also be a cloud server that provides basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, a cloud storage, a network service, cloud communication, a middleware service, a domain name service, a security service, a CDN, and a big data and artificial intelligence platform.

A user may utilize client 110 to communicate data with blockchain network 120 to query or update shared data commonly maintained by node devices 121 in blockchain network 120. In the blockchain network 120, each node device 121 may receive input information while performing normal operations and maintain shared data within the blockchain network based on the received input information. In order to ensure information intercommunication, data communication links may exist between node devices 121, and node devices 121 may perform data transmission with each other through the data communication links. For example, when any node device 121 in the blockchain network 120 receives input information and broadcasts the input information in the blockchain network 120, other node devices in the blockchain network 120 may acquire the input information according to a consensus algorithm and store the input information as shared data.

Each node device 121 in the blockchain network 120 may store one same blockchain (Block Chain). The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and a distributed database which ensures data to be untrustworthy and counterfeitable in a cryptographic mode. The block chain is composed of a plurality of blocks connected in sequence, and when new data needs to be written into the block chain, the data is gathered into a newly generated block, the newly generated block is linked to the end of the block chain, and the newly added block on each node device 121 can be guaranteed to be identical through a consensus algorithm. The data of the current block is recorded in the block body of each block, and the Hash value (Hash) of the previous block connected with the current block is stored in the block head of each block, and if the transaction data in the previous block changes, the Hash value of the current block changes accordingly. Therefore, the data uploaded to the blockchain network is difficult to tamper, and the reliability of the shared data can be improved.

Blockchain network 120 may be of many different types, such as a public chain, a private chain, or a federation chain that are collectively built by business principals that have business relationships. For example, when a user publishes a paper, a novel or other original content on a network platform, an electronic evidence can be formed for the content originality of the related content based on a network page evidence storage mode. On the basis, a alliance chain form can be adopted, and block chain node deployment can be carried out on a service platform for users to use the certificate storage service, notarization departments in different regions, copyright bureaus and other institutions. The user can initiate a certificate storing service request through the block chain node corresponding to the service platform, when service data are generated, synchronous sharing of the data can be performed by using decentralized distributed storage characteristics of the block chain, and a corresponding certificate storing service data is stored on each block chain node.

Fig. 2 schematically illustrates a proof principle block diagram of a proof service platform provided in some embodiments of the present application. As shown in fig. 2, a user 201 as an initiator of the evidence saving service may log in a client on a terminal device such as a mobile phone or a computer, so as to submit an evidence saving service request to a service platform 202 through the client, where the evidence saving service request carries information related to an evidence saving service of a web page, for example, the information may include web page address information of the web page as an electronic evidence, such as a Uniform Resource Locator (URL) of the web page.

The service platform 202 may store and process information submitted by a user, and publish the information to the web snapshot service platform 203 in the form of a message broadcast subscription. After receiving the pushed message, the web snapshot service platform 203 may perform a web snapshot operation on the network page to be certified based on the relevant information, obtain a snapshot picture file including the entire content in the network page, and upload the snapshot picture file to the service platform 202.

The service platform 202 extracts the data digest from the certified data and saves the data digest onto the blockchain 204 by invoking an intelligent contract. The data digest of the credential data may be obtained by performing a Hash Function (Hash Function) on the credential data, and the Hash Function may include, for example, SM3 or SHA 256. Smart contracts are computer protocols that are intended to propagate, validate, or execute contracts in an informational manner, which may provide a secure method over traditional contracts and reduce the transaction costs associated with the contracts. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.

And other organizations such as notarization departments and copyright bureaus which are used as the block chain nodes can also store the block chain which is the same as the service platform, so that the efficient and reliable storage of the electronic evidence is realized. While the electronic evidence storage is realized, the user 201 can inquire and verify the electronic evidence stored on the block chain through the service platform 202, and can also notarize the corresponding electronic evidence through the notarization department 205, thereby effectively authenticating the reliability of the electronic evidence.

The following describes in detail the network page authentication method, the network page authentication device, the computer readable medium, the electronic device, and other technical solutions provided in the embodiments of the present application with reference to the specific embodiments.

The network page evidence storage method utilizes a block chain network to establish a credible computing environment, enables an evidence storage block chain to become a bottom infrastructure of a content platform, uses cryptography to ensure the safety of access and transmission, and can realize the accounting technology of data distributed storage, difficult tampering and repudiation prevention. The block chain technology can be used for carrying out safety protection on data in the whole life cycle of generation, collection, transmission and storage of the obtained electronic evidence, preventing tampering and carrying out auditing and trace chaining of data operation, thereby providing an effective means for related institution examination. Electronic data needing to be stored in certificate is recorded in a transaction form based on a block chain, a timestamp is printed, the electronic data is recorded in the block, the certificate storing process can be completed, and a scheme design based on a alliance chain can enable a plurality of enterprises participating in alliance to keep data consistency, so that the possibility of data loss or falsification is greatly reduced.

The user as the evidence storing request party can perform data communication with the block chain node for processing the network page evidence storing service through the login client, so as to initiate a network page evidence storing request to the node device as the service platform. FIG. 4 schematically illustrates a client interface for registering and logging into a web page credentialing service platform in one application scenario. As shown in fig. 4, in this application scenario, an individual or an enterprise may register an account on a client and perform a evidence-saving and evidence-obtaining operation on a web page. The personal user can register by inputting a personal mobile phone number, a graphic verification code, a short message verification code and a password, and can carry out real-name authentication by uploading a personal identification after submitting the personal mobile phone number, the graphic verification code, the short message verification code and the password. Enterprise users may register by providing information related to enterprise licenses and the like. After the registration and the login are completed, the user can input service request data for initiating the network page certificate storage service and transmits the certificate storage service request carrying the service request data to the back-end service platform. In the embodiment of the present application, the service request data may include, for example, account information, identity information, a web page address of a web page requesting for storing a certificate, and other various information of the current user.

In some embodiments of the present application, the service request data is obtained by checking original data input by a certificate storing requester through a data acquisition terminal; the method for verifying the original data input by the storage certification requester through the data acquisition terminal may include: receiving original data input by a certificate storing request party through a data acquisition end; performing integrity check on the original data to determine whether the original data contains complete service request content; when the original data passes the integrity verification, performing regular verification on the page address of the network page to be verified carried in the original data to determine whether the page address has a legal network page address format; and when the page address has a legal network page address format, determining the original data as the service request data passing the verification.

In step S320, the network page to be certified is accessed according to the page address, and the web snapshot processing is performed on the network page to be certified, so as to obtain a web snapshot image including the complete page content of the network page to be certified.

After receiving the network page evidence storing service data, the service platform serving as the current block link node can perform web page snapshot processing on the network page to be evidence stored according to the page address carried in the network page evidence storing service data to obtain a corresponding web page snapshot image. The web page snapshot image is a complete backup for storing the web page content in a picture form, and is different from an image directly shot by a camera, a mobile phone and other equipment or a part of web page image acquired by a screen capturing mode and the like, and the web page snapshot image can ensure the content integrity of a network page.

In some embodiments of the present application, the accessing the to-be-stored-license web page according to the page address in step S320, and performing a web snapshot process on the to-be-stored-license web page to obtain a web snapshot image including a complete page content of the to-be-stored-license web page may include steps S321 to S323 as follows.

Step S321: and extracting the page address of the network page to be certified and the service code associated with the page address from the network page certification storing service data.

Step S322: and sending the page address and the service code to a web page snapshot service platform so that the web page snapshot service platform accesses the network page to be certified according to the page address and carries out web page snapshot processing on the network page to be certified.

Step S323: and acquiring a web page snapshot image which is returned by the web page snapshot service platform and contains the complete page content of the network page to be stored and certified according to the service code.

The service code is a unique code for identifying the current network page evidence storing service, and in the process of carrying out the web page snapshot processing, the association relationship between the page address of the network page to be stored and the web page snapshot image can be established by utilizing the service code.

The web snapshot Service platform may be a cloud server compliant with a cyberscurity security Compliance Service (cyberscurity security Compliance Service) for providing a web snapshot Service. The network security level protection system is realized by complete and systematic network security level protection compliance construction and evaluation service. The method can realize asynchronous and credible web snapshot processing based on the web snapshot service platform, and can greatly improve the processing efficiency and the processing safety of the network page certificate storage service when facing a large amount of network page certificate storage service requests.

In some optional embodiments, the sending the page address and the service code to the web page snapshot service platform in step S322 may include: packaging the page address and the service code into a message to be processed; sending the message to be processed to a switch so as to distribute the message to be processed to a message queue bound with the switch through the switch; and broadcasting the to-be-processed message stored in the message queue to a webpage snapshot service platform subscribing the message queue, so that the webpage snapshot service platform analyzes and processes the to-be-processed message to obtain a page address and a service code.

The broadcast subscription mechanism based on the message broker can further improve the data processing efficiency. Fig. 5 schematically shows a functional block diagram of data transmission based on message proxying in an application scenario according to an embodiment of the present application. As shown in fig. 5, the message middleware 510 is software for providing a message broker service, and may be, for example, software including RabbitMQ, Kafka, ActiveMQ, ZeroMQ, rocktmq, and the like. Message middleware 510 may be primarily composed of a switch 511 (exchange) and a message queue 512 (queue). The service platform as the message producer 520 may first encapsulate the page address and the service code into a message to be processed, and send the message to be processed to the switch 511, and the switch 511 routes and distributes the message to be processed to each message queue 512 according to a binding relationship (binding). The web snapshot service platform as the consumer 530 may subscribe to each message queue 512, and after a new message to be processed is received in a certain message queue, the web snapshot service platform subscribing to the message queue may obtain the message therefrom and analyze and process the message, thereby obtaining a page address and a service code encapsulated in the message, and completing data transmission from the service platform to the network snapshot service platform. Optionally, after broadcasting the to-be-processed message stored in the message queue to the web snapshot service platform subscribing to the message queue, when the web snapshot service platform receives the to-be-processed message, a message confirmation notification corresponding to the to-be-processed message may also be generated; in response to the message acknowledgement notification, pending messages may be removed from the message queue, avoiding the occurrence of repeated consumption of messages.

In some optional embodiments, the obtaining, according to the service code, the web snapshot image including the complete page content of the web page to be certified, returned by the web snapshot service platform in step S323 may include: monitoring a file storage area corresponding to the web page snapshot service platform; when a new image file is generated in the file storage area, file identification information of the image file is acquired; analyzing the file identification information to obtain a service code carried in the file identification information; and determining the image file as a web page snapshot image of the network page to be certified according to the service code. The method is suitable for asynchronous processing of the web page snapshot image by monitoring the file storage area, and when a new image file is generated, the corresponding relation between the image file and the network page to be credited is searched and determined according to the service code, so that the web page snapshot image corresponding to the network page to be credited is accurately positioned.

In step S330, a preset hash digest algorithm is used to perform digest extraction on the web snapshot image to obtain a page image digest for uniquely identifying the web page to be certified, where the page image digest is a hash value with a fixed length. The hash digest algorithm for the web page snapshot image may be obtained by performing a hash process on the web page snapshot image through a hash function such as SM3 or SHA 256. The data processing efficiency is improved by the abstract processing, and the page image abstract extracted based on the Hash abstract algorithm has uniqueness so as to uniquely identify the network page to be stored with evidence.

In step S340, the page image abstract is subjected to consensus authentication, and the page image abstract passing the authentication is subjected to uplink processing, so as to store the page image abstract on a verification blockchain maintained by the blockchain network.

In some embodiments of the present application, the page image summary may be separately ul-stored. On this basis, step S340 may further include: storing the page image abstract into a block to be uplink of a current block chain node; when the block generation condition is met, broadcasting the block to be uplink to the block chain network so as to perform consensus authentication on the block to be uplink through other block chain link points in the block chain network; when the authentication is passed, the block to be linked is linked to a verification block chain maintained by the block chain network.

In other embodiments of the present application, the page image summary and the corresponding network page evidence storing service data may also be jointly uplink stored. On this basis, step S340 may further include: performing association processing on the page image abstract and the network page evidence storing service data to obtain data to be uplink, and storing the data to be uplink into a block to be uplink of a current block link point; when the block generation condition is met, broadcasting the block to be uplink to the block chain network so as to perform consensus authentication on the block to be uplink through other block chain link points in the block chain network; when the authentication is passed, the block to be linked is linked to a verification block chain maintained by the block chain network.

The current blockchain node as a service platform can receive a large number of network page evidence storing service requests, and processing results aiming at the network page evidence storing service requests are stored in a to-be-uplink block of the current blockchain node in a transaction data form. Once the predetermined block generation condition is satisfied, the data in the block to be uplink transmitted can be broadcasted in the blockchain network for other blockchain nodes in the blockchain network to perform consensus authentication. The tile generation condition may include, for example, one or more of a time condition and a data amount condition. For example, the block generation period may be preset, and a new block is generated and uplinked at a fixed time interval in the embodiment of the present application; or a data volume threshold may be preset, and when the data volume of the service data in the block to be uplink reaches the data volume threshold, a new block may be generated and uplink is performed on the new block. Mechanisms to implement consensus authentication may include, for example, Proof of workload (Proof of Work, PoW), Proof of rights and interests (PoS), Proof of equity authority (released Proof of stamp, DPoS), Proof of Elapsed Time (Proof of Elapsed Time, PoET), and so forth.

In some embodiments of the present application, various business structures related to electronic evidence, such as notarization departments and copyright authorities, may be added to the blockchain network as blockchain nodes. The notarization department or other mechanisms capable of providing notarization service serve as notarization nodes, and the notarization nodes can synchronously store the evidence storage block chain identical to the business platform. When the electronic evidence needs to be notarized, a user can broadcast a notarization request of the evidence-stored data aiming at the certified network page on the block chain network through the service platform; after the notarization node processes the notarization request of the evidence stored data, the user can continue to receive the notarization result of the evidence stored data, which is returned by the notarization node in the block chain network and aims at the page of the certified network, through the service platform.

In step S350, the certificate storing uplink information of the network page to be certified is determined according to the uplink result of the page image abstract, and a certificate storing uplink certificate for certifying the certificate storing position and the certificate storing time of the network page is generated according to the certificate storing uplink information.

In some embodiments of the present application, after storing the page image abstract on a certificate-storing blockchain maintained by a blockchain network, a user may receive, through a service platform, certificate-storing uplink information returned by the blockchain network, where the certificate-storing uplink information includes a block height and a block address of a block where the page image abstract is located for indicating a certificate-storing position of a network page, and further includes an uplink timestamp for indicating a certificate-storing time of the network page; and then generating a certificate storing uplink certificate for proving the certificate storing position and the certificate storing time of the network page according to the certificate storing uplink information. In some optional embodiments, the certified location of the certified network page may be determined according to the block height and the block address in the certified uplink information; the evidence storing time of the certified network page can be determined according to the uplink time stamp in the evidence storing uplink information; and generating the certificate storing uplink certificate for displaying the certificate storing position and the certificate storing time based on the certificate storing uplink information.

Fig. 6 schematically shows a certificate storing interface for storing certificates of web pages in an application scenario according to an embodiment of the present application. As shown in fig. 6, each piece of electronic evidence may be stored in a virtual "evidence storage room" in which web page information 601 and a blockchain certificate 602 of a web page as electronic evidence are recorded. The web page information 601 includes information such as a storage name, storage time, a web page address, a chaining state, a block chain code, and a web page snapshot image of the web page as an electronic proof. The blockchain Certificate 602 is a Certificate-storing uplink Certificate generated after the network page completes Certificate-storing uplink, and may be embodied as an Electronic Certificate of identity (Certificate of Electronic event). In the blockchain certificate 602, two contents of certificate basic information and certificate storing information may be recorded, where the certificate basic information may include information such as a certificate number, a certificate holder, a certificate number, a platform account number, and a certificate validity period, and the certificate storing information may include information such as an evidence name (which may be the same as or different from the certificate name), a certificate storing time (which may be the same as or different from a storage time of the electronic evidence), an evidence size, an evidence code, a digital fingerprint (i.e., a hash code), and a blockchain code.

The following further describes the evidence storage management process of the network page evidence storage method provided in the above embodiment with reference to a specific application scenario. Fig. 7 schematically shows a flowchart of the license management in an application scenario according to an embodiment of the present application. As shown in fig. 7, the method for performing the license management in the application scenario may mainly include the following steps.

Step S701: and the user submits a network page evidence storage request to the service platform through the client.

The user can fill in the evidence storing information through the client (or the web interface), and the evidence storing information mainly comprises the information of an evidence storing name, a web page address of a to-be-stored network page and the like, wherein the to-be-stored network page can comprise one or more network pages. For example: https:// xxxxx.com; https:// yyyyy.com. The individual user can fill in information by logging on the client, and the enterprise user can also implement the authentication service by calling an application program interface (API interface).

The client or the data acquisition terminal providing the web interface is installed to check the information input by the user (mainly checking the integrity of the input information and the legality of the URL website), and after the check is passed, a network page authentication request can be generated based on the information input by the user and submitted to a back-end service platform.

Step S702: and the service platform analyzes the network page evidence storing request to obtain network page evidence storing service data and submits the network page evidence storing service data to a data cache region.

After receiving the network page evidence storing request, the service platform can analyze and process the network page evidence storing request to obtain the carried network page evidence storing service data. The service platform can check the validity of the network page certificate storage service data, and the check content can include the user identity, the data length, the data size and the like. After passing the validity check, the network page evidence storing service data is cached to be submitted to a data caching area, for example, the network page evidence storing service data may be stored in a Redis database.

Step S703: and the service platform sends the message to be processed to the message middleware.

The page address and the service code of the network page to be processed are packaged into a message to be processed, the service platform is used as a producer to send the message to be processed to MQ message middleware for broadcasting, the message middleware can process the message based on an Advanced Message Queue Protocol (AMQP), and the AMQP protocol is a communication network protocol for storing and forwarding the message in the distributed system. The message to be processed can be delivered to the consumer (consumer) by the producer (producer/publisher) through the message broker (broker).

Step S704: and the message middleware broadcasts the message to be processed to the web page snapshot service platform.

The message middleware can broadcast the messages to be processed to all web page snapshot service platforms subscribed to the message queue, wherein the web page snapshot service platform can be understood as a consumer of the message middleware.

Step S705: and the web page snapshot service platform calls the web page snapshot script to perform web page snapshot processing.

After receiving the message, the web page snapshot service platform can analyze the message, acquire the service code and the web page address URL link, and realize automatic web page snapshot processing based on automation and browser technology, namely, selenium + Webdriver technology. Specifically, the browser can be automatically opened based on the WebDriver, and after the browser object is obtained, the web address URL can be accessed in a get mode. For the opened web page, the web page snapshot processing which is automatically saved as a picture can be performed on the opened web page.

Step S706: and the web page snapshot service platform saves the web page snapshot image to a specified file storage area.

After the web page snapshot image is generated by the web page snapshot service platform, the business code and the snapshot generation date are used as image names and are stored in a/tmp/images directory. For example, the image name of a web page snapshot image may be: FW492765617347235840_2020-08-17. png.

Step S707: the service platform monitors an image file generation event in the file storage area.

When the asynchronous webpage snapshot generating mode is adopted, a file monitoring service can be started on the service platform and used for monitoring whether the picture file on the webpage snapshot service platform is successfully generated or not, and if the picture file is successfully created, the webpage snapshot image file path can be obtained. The specific file listening service process may include: monitoring a certain directory corresponding to the web page snapshot service platform, such as a/tmp/images directory. When the service platform is started, a background monitor service is started to monitor whether a new file is generated under the tmp/images directory, and operations such as modification and deletion of the file or the folder can be monitored.

Step S708: and the service platform analyzes the image name of the newly generated webpage snapshot image to obtain a service code.

The service platform analyzes the service code according to the image name of the newly generated web page snapshot image, for example: the name of the image file is: FW 492765617347235840-2020-08-17. png, after analysis processing, the corresponding service code can be obtained as follows: FW 492765617347235840.

Step S709: and the service platform takes out the network page evidence storage service data matched with the service code from the data cache region according to the service code.

And the service platform takes out the corresponding network page evidence storage service data from the cache Redis according to the service codes. The method mainly comprises the steps of webpage snapshot URL, certificate storage name, user-defined remark information and the like.

Step S710: and extracting a page image abstract from the page snapshot image, and performing uplink processing on the page image abstract.

And the service platform performs abstract extraction processing on the web page snapshot image by using a preset Hash abstract algorithm to obtain a web page image abstract for performing unique identification on the web page to be certified. The SM3 or SHA256 hash value of the web page snapshot image file may be calculated based on a hash digest algorithm. Among them, the SM3 algorithm is an encryption algorithm that conforms to the rules of the national cryptography algorithm. After the extracted page image abstract is subjected to consensus authentication, the page image abstract is stored to a certificate-storing block chain maintained by a block chain network through chain linking processing.

Step S711: the blockchain service returns the uplink result of the page image summary.

After the evidence-stored data uplink is completed, the block chain can return a data uplink result to the service platform, and the evidence-stored uplink information of the network page can be determined based on the data uplink result, wherein the evidence-stored uplink information mainly comprises the block height and the block address of the block where the page image abstract of the evidence-stored position of the network page is located, and further comprises information such as an uplink timestamp for representing the evidence-stored time of the network page.

Step S712: and the service platform generates the certificate storing uplink certificate according to the certificate storing uplink information.

The certificate store uplink certificate may include: certificate number, holder, certificate number, account number, validity period, evidence name, evidence storage time, evidence size, evidence code, data fingerprint, block ID (block address) and other related information.

Step S713: the user inquires the web page snapshot data and the uplink information.

The user can inquire the relevant files such as the web page snapshot image, the certificate-storing uplink certificate and the like through the service platform (enterprises can also use the interface), so that the later-stage verification use is facilitated.

In the network page evidence storing method of the application scenario example, reliable access to evidence storing data can be realized based on the technical characteristics of the block chain, and the requirement that the electronic evidence cannot be tampered is met. By adopting the automatic webpage snapshot technology, full-screen webpage snapshot can be carried out on the network page to be certified, and snapshot can be carried out on a long webpage instead of the screenshot of the user, so that the problems of tampering operation and incomplete snapshot of the user on the certified file are solved, and the legality and authenticity of the electronic evidence are ensured. And the mode of extracting the webpage snapshot data abstract and attaching the credible timestamp is adopted for uploading and storing the evidence, so that the electronic evidence can be managed and operated more efficiently and reliably.

It should be noted that although the various steps of the methods in this application are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the shown steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
