For example, a and/or B, may represent: three cases of a alone, B alone, and a and B together exist, and a character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The application provides a webpage operation process recording method, which is used for recording the whole process of webpage browsing and operation of a user, generating recorded data capable of being used for playback and simultaneously generating effective operation evidence, and the following briefly explains the principle adopted by the method.
Firstly, analyzing the recording method of the prior art for the webpage operation process, the existing defects are mainly expressed in two aspects:
firstly, the recorded data is used for playback, and flexible control as video cannot be realized, and the main reason is that in the prior art, a web page operation process is recorded by a method for recording web page snapshot data and web page snapshot difference data, taking web page browsing and operation for 10 minutes as an example, an operator performs information filling, web page jumping, information submission and the like, which can cause hundreds of changes of web page snapshot content.
Secondly, the prior art lacks a security acquisition and verification mechanism in the process of recording data, so that the prior art is only suitable for common application scenes for generating user operation trajectory data, and has a major defect if the prior art is applied to more strict scenes such as internet insurance, fund transfer and the like.
In the embodiments provided in the present application, the above first problem is solved by recording a plurality of key frame data, and if 10 key frames are inserted as in the above example, the amount of computation can be reduced by about one order of magnitude, but the storage of key frames causes another problem that the amount of recorded data increases, and the key frame data stored as in the above example may increase by one order of magnitude, based on which the present application solves the above problem of recording too large data by using difference computation between key frames and storing difference data. When the finally generated recording data is used for playback, if the playing is required to be executed from the 9 th minute as in the above example, a key frame closest to the specified time point is searched, the webpage data of the key frame is firstly calculated according to the difference relation between the data stored in the key frame and other key frames, then the webpage content data of the specified time point is finally calculated according to the webpage content change data recorded between the key frame and the specified time point, and the webpage is displayed, so that the playing according to the specified position is realized, and the calculation amount is effectively reduced.
Analyzing the second problem existing in the prior art, if the second problem needs to be solved, acquiring the recorded data of the webpage operation process in a public and fair environment, wherein the acquired data can be approved by a webpage provider and a webpage operator; the collected data has no possibility of tampering, and a verification mechanism is provided to discover the operation in the collection process and the abnormity in the data. According to the scheme provided by the embodiment of the application, the data acquisition of the webpage operation process is carried out at the client (browser), and no processing related to the data acquisition and recording is allowed to be executed outside the client before the final operation evidence is not generated; according to each change of the webpage data or each webpage operation, an operation credential is generated for the recorded data by applying a message digest algorithm, each operation credential is established on the previous operation credential, and finally, an unmodified operation credential is generated, each credential generation is effective and fixed for the previous operation credential, and the above mechanism ensures that the webpage operation data is not allowed to be modified after being generated; in the process of acquiring the webpage data, two modes are provided to ensure the validity of the acquired data, firstly, the operation environment information, the webpage program, the request and interaction information of the webpage and the outside, the data environment information of the webpage operation, the user operation behavior information and the like of the webpage are acquired at the same time when the webpage operation process recording data is acquired, operation process verification data is generated and used for restoring the webpage operation process, the validity of the recorded webpage operation process recording data is verified according to the restored webpage operation process, secondly, when the webpage snapshot data content changes or the webpage operation is acquired, the operation process verification data is generated based on the webpage snapshot data content, the operation process verification data comprises related operation information and data content to be verified, and the operation process verification data is sent to a verification server for verification, and the verification server verifies the validity of the data to be verified according to the operation generated by the client and returns a verification result, so that the method is a mode for verifying the recorded data in the webpage operation process in real time.
Fig. 1 shows a schematic flow chart of a possible record of a web page operation process, which includes the following steps:
s101, collecting data in webpage snapshot data content, and creating a webpage record data key frame based on the collected data;
s102, calculating and generating webpage content change data based on the change of the webpage snapshot data content in the webpage operation process, and recording the time information of the change;
s103, collecting operation process verification data based on the webpage operation process;
and S104, storing the acquired data in a structured mode, and generating webpage operation process record data.
The following is detailed for the above steps:
in S101, the web page record data key frame is created in the web page operation process, and is used to store the web page snapshot data content in an operation state, and the complete web page snapshot data content can be obtained directly or through calculation according to the web page record data key frame. In the recording process of the webpage operation, a plurality of webpage recording data key frames can be created according to the recording requirements and the data characteristics of the webpage snapshot content, and the specific creation mode is as follows: the method comprises the steps of recording the starting time of an execution operation process, the starting time of webpage loading, completing the first loading of a webpage, jumping the webpage, exceeding a preset percentage of webpage data content, reaching a preset value of webpage operation times, reaching a preset value of webpage content change times, establishing according to a preset operation stage, establishing according to a preset time interval and the like.
In S102, the content of the web snapshot data changes, according to the type of the content of the web snapshot data, including HTML data changes, DOM changes, CSSOM changes, and the like, it should be noted that the content of the web element object also includes internal changes of the web element object, such as canvas elements, video elements, and the like, when the internal changes of the element occur (for example, the drawing content contained in canvas changes), the HTML, DOM, and the like corresponding to the web snapshot do not change, and therefore, the internal changes of the web element need to be recorded in a corresponding recording manner. And recording the time information of the change of the webpage snapshot data content, and setting the execution time of the corresponding playback instruction during playback.
It should be noted that at least one, and possibly a plurality of, above steps S101 may include a plurality of combinations of steps S101 and S102, each S102 having a corresponding step S101, but there is a case where there is a separate step S101 and there is no step S102 corresponding thereto.
In S103, the operation process verification data is mainly used to verify the validity of the data collected or recorded in the web page operation, S101 and S102, that is, to ensure that the web page snapshot content data and the web page content change data collected in the web page operation process are true and valid, or can be verified, and a specific verification manner is described in detail in the following embodiments. The operation process verifies the content contained in the data, such as the generated webpage operation data, the data used for verification, or the data generated based on the data, wherein the data used for verification contains the data content to be verified, and the data to be verified is verified by a verification terminal or a server according to the generated webpage operation to obtain the final verification result.
And S104, storing the acquired data to generate webpage operation process record data, wherein the storage mode comprises storage according to a tree structure, relational storage and the like, and the specific example is illustrated in the following embodiments. In addition, the method also comprises the steps of storing the webpage operation process record data, storing the related resource file records in the webpage record data key frame and the webpage content change data, and generating resource file record data, wherein the resource file record data comprises resource files such as CSS files and pictures.
In a preferred implementation of the above embodiment, a data model is established based on the structure of the web page snapshot data content, key frame (web page record data key frame) data is generated based on the data model, and web page content change data is generated based on the data model analysis. If the data model adopts a tree structure, key frame data in a JSON form is generated based on the data model, and when the webpage content changes, a webpage content change data record is recorded and generated based on the node information, change property, change content and the like which change in the data model corresponding to the webpage content change.
It should be noted that, the above steps of collecting the web page record data key frame data, collecting the web page content change data, collecting the operation process verification data, and generating the web page operation process record data are all performed at the client (the browser executing the web page operation) before the valid operation credential is not generated. In an optional implementation manner, according to the above, after the client generates the valid operation credential, the operation credential and/or the web page operation process record data are stored at the client and/or the server.
Optionally, the verification data of the web page operation process generated in S103 is sent to a verification server or a verification terminal for real-time verification, and the valid data of the web page operation process record is controlled and stored in S104 according to the verification result returned by the verification server or the verification terminal. It should be noted that, in this implementation, the web page operation procedure record data stored in S104 may not include the operation procedure verification data.
By the embodiment, the recording mode of combining the key frame data and the webpage content change data is adopted, the generated webpage operation process records data, and flexible playing control is supported; and verifying the data during the data recording process to ensure the recorded data to be true and effective, or acquiring data capable of verifying the webpage operation process during the data recording process to generate data capable of verifying the validity of the recorded data during the webpage operation process so as to ensure the recorded data to be verifiable.
In one possible implementation scenario, the data of the key frames recorded during the operation of the web page includes the following two ways: recording complete webpage content data, generating independent webpage record data key frame data, or recording difference data information between the webpage record data key frame and a specified webpage record data key frame, and generating difference webpage record data key frame data. Fig. 2 shows an example of recording key frames and web page changes (i.e. web page content changes) in the web page operation process, as shown in the figure, 4 key frames are generated according to the recording requirement, wherein, the key frame a and the key frame D are independent key frames, such key frames store complete web page data content, and in addition, the key frame B and the key frame C are differential key frames, i.e. the key frame B records the difference information with the key frame a, and the key frame C records the difference information with the key frame B. Between every two key frames, a plurality of web page change data may be included, for example, a web page change a and a web page change B are included between the key frame a and the key frame B, where the web page change a records the web page change on the basis of the key frame a, and the web page change B records the web page change on the basis of the web page change a.
The implementation principle of the above possible implementation scenarios has the following two advantages:
first, the generated data recorded in the operation process of the web page solves the problem of performing playback at a specified time point during playback, and facilitates flexible playback control as a video, as described in detail in relation to the related embodiments of the playback section.
And secondly, the storage capacity of data is reduced, and the storage is facilitated. According to the setting requirement of the independent key frame, the method is usually adopted when the webpage content data are changed greatly or completely, so that the data recorded by the independent key frame are necessary webpage content data, and in addition, the differentiated key frame and the webpage change data are recorded in a volume minimized mode, so that the aim of controlling the volume of the data is fulfilled as a whole.
In one possible implementation scenario, as shown in fig. 3, operation procedure verification data is collected based on a web operation procedure, and the following steps are performed:
s301, collecting running environment information of a webpage;
s302, collecting a webpage program;
s303, acquiring requests and interactive information between the webpage and the outside;
s304, collecting data environment information of webpage operation;
s305, collecting user operation behavior information;
and S306, generating webpage operation process verification data.
In the above implementation scenario, the information collected in S301 to S305 is used to generate verification data of the operation process, and when the verification data of the web page operation process is used for verification, the above various data are obtained through parsing, and the operation environment and the operation process of the web page operation performed by the user are restored based on the data, so as to verify the validity of each item of data included in the record data of the web page operation process. In some possible embodiments, the collecting of the verification data for the web page operation process includes one or more of S301 to S305, but is not limited to the information included in S301 to S305.
The web page operating environment information collected in step S301 is used to set an operating environment for performing verification, that is, to set relevant parameters and data thereof; the web page programs collected by the S302 include, but are not limited to, a front-end service program, a digital signature of a server-end service program, a recording program used for implementing the method of the present application, and the like; the web page and the external request and interaction information in S303 include, but are not limited to, interaction information between the web page and the server, request and interaction information between the web page and the local operating system, and request and interaction information between the web page and the support operating environment of the web page, such as requesting data from the server, obtaining data from the server, selecting a local file to upload, and the like; s304 acquired data environment information of the web page operation, which is intended to record the data environment of the browser when the web page operation starts or the recording starts to be executed, where the acquired data includes contents such as a local database, a local storage, and a cache stored in the browser; the user operation behavior in S305 is various operations performed on the web page by the user, including clicking, dragging, inputting, page sliding, and the like.
Through the method, the running environment, the external interaction, the user interaction, the data environment, the program and the like in the webpage operation process are subjected to multi-dimensional data acquisition, so that the necessary condition for constructing the verification execution running environment is met, the webpage operation process is conveniently restored in the verification execution running environment, and the recorded validity of the recorded webpage operation process recorded data is verified based on the restored result.
It should be noted that, the recording program for implementing the method of the present application is required to be implemented at a front end (client), so as to ensure that the implementation method of the present application is public and transparent. Based on the above implementation, the following effects can be obtained: for a webpage operator, a recording program applied to the webpage operation process is located at a client side and runs, and the program content of the recording program is public, so that the possibility that a webpage provider modifies the recorded data does not exist; for a webpage provider, the operation process verification data is used, the environment and the process of webpage operation performed by a webpage operator can be restored, and the validity of the recorded data is verified, so that the possibility that the webpage operator modifies the recorded data of the webpage operation process is eliminated. Thus, the recorded data is trusted for both parties.
According to the embodiment, a verification and verifiable mechanism is provided for the recorded data of the webpage operation process, the validity of the collected and recorded data of the webpage operation process is ensured, or the reason for obtaining the problem can be verified when the problem of the data of the relevant record is met, and the guarantee is provided for finally generating the evidence of the webpage operation process.
In another possible implementation scenario, during the operation of the web page, the operation occurring in the web page and the generated data change of the web page are verified in real time, as shown in fig. 4, the web page operation is performed at the web page operation client, and the real-time verification is performed by an independent verification server (or verification terminal), and the detailed steps are as follows:
s401, collecting webpage operation, webpage snapshot data content or changes thereof at a webpage operation client;
s402, operating a client on a webpage to generate verification data of the operation process;
s403, verifying the webpage operation and the webpage data content change of the client side according to the operation process verification data at the verification server;
s404, generating a verification result at the verification server;
s405, operating the client on the webpage, and judging a verification result;
s406, when the webpage operation and the recorded data are normal, the subsequent processing is executed at the webpage operation client;
s407, the web page operation and the recorded data are abnormal, and the abnormal processing is executed at the web page operation client.
It should be noted that the web page operations in S401 and the present application above are not simply understood as web page operations of user behaviors, which include but are not limited to various web page operation behaviors triggered by user behaviors, network interactions, programs, data, execution environments, and the like, such as button clicks, web page loading completion, execution of a program by a timer in a web page program, execution triggered by server pushing, and the like.
S402 generates operation process verification data according to the collected web page operation, web page snapshot data content, or changes thereof, where the generation requirement of the operation process verification data is that a verification end can complete verification operations according to web page operations that the verification end performs on a client and recorded web page operation process record data, for example, the operation process verification data may include web page operation information and data that the client performs, data used for verification, and the like, where the data used for verification includes data content to be verified, e.g., after the web page snapshot content data of the client changes, a message digest is generated for the latest web page operation process record data using a message digest algorithm, and the message digest is used as the data content to be verified.
And the verification server in S403 verifies the validity of the web page operation, the generated web page content data, and the generated web page operation process record data generated by the client according to the operation information and the data information for verification included in the operation process verification data. In a preferred implementation manner, a verification execution environment which runs synchronously with a webpage operation environment is simulated and established in a verification server, after operation process verification data is received, webpage operations contained in the verification execution environment are executed in the same way, and then the data to be verified is verified according to webpage data generated in the verification execution environment. If the generation manner of the operation procedure verification data corresponding to S402 is illustrated, the server side performing the verification performs the web page operation according to the same steps as the client side, generates the web page operation procedure record data, generates the message digest for the web page operation procedure record data, and compares the message digest with the message digest included in the data to be verified to complete the verification. The realization principle of the verification mode is that webpage operations of the client and the verification server are synchronously executed, webpage data finally recorded by the client is verified based on the webpage data of the server, preferably, for the request and interaction between the client and the business server, the verification server directly obtains server response data received by the client from the business server according to the webpage operations, and executes verification, thereby effectively preventing the client from damaging the webpage data of the client by forging webpage requests and forging server response data.
According to the above, the verification server verifies the authenticity of the client operation, the client webpage data and the recorded webpage operation process record data through the operation process verification data, so that the operation process verification data needs to meet the verification requirement of the verification server, and the operation process verification data includes data to be verified, including but not limited to the following modes: the webpage operation process records data or generates a message abstract for the data; recording the newly added data content of the data or the message abstract generated for the newly added data content in the webpage operation process; web page snapshot data content or a message abstract generated for the web page snapshot data content; web page content change data or a message digest generated for the web page content change data; and extracting data of one or more webpage elements according to the specification from the webpage snapshot data content or generating a message summary for the webpage elements. It should be noted that, the operation process verifies the web page operation information included in the data, and also includes data content related to the web page operation, such as for an input operation, including the input data content.
And executing S404 to generate a verification result and sending the verification result to the webpage operation client at the verification server, executing S405 to judge the verification result at the webpage operation client, if the verification is passed, executing subsequent processing by S406, and if the verification is not passed, executing abnormal processing by S406. Preferably, the verification result generated in S404 includes not only the result information of whether the verification is passed, but also the verification code information generated by the verification server based on the current verification, and ensures that the verification code cannot be generated based on the data of the client, for example, a message digest is generated together based on the verified data, the web page operation information, and the character string independently retained by the server. Optionally, the verification server sends the generated verification result to the service server at the same time. Optionally, the verification code information is stored in the webpage operation process record data at the client. In a preferred implementation manner of this embodiment, the subsequent operations executed in S406 are all executed based on the verification result information (e.g., the received verification code information) obtained in the previous step, such as: the verification result information is carried when the request is sent to the service server to indicate that the last step is verified and the request of my is received and processed, and the service server verifies the validity of the request of the client according to the verification result information sent when the verification server executes the verification of the last step. For another example, the web page operation client sends operation process verification data to the verification server, the operation process verification data is generated based on the last verification result information, and the verification server executes the verification operation on the basis of checking the historical verification validity.
In an optional implementation manner of this embodiment, the verification server and the client perform encryption transmission of the operation verification data and the verification result data in a public key, a private key, and a digital signature manner to ensure the security of data sent by the client and the verification server, the client performs identity verification, for example, the verification server generates the public key and the private key, the verification data sent by the client is encrypted by the public key, the verification server receives and decrypts the data by using the private key and performs verification, when sending the verification result data, the verification server generates a message digest for the sent verification data and encrypts the digest by using the private key to generate a digital signature, and sends the generated digital signature and the verification result data to the client together, the client decrypts the message digest by using the public key to obtain the digest, verifies the verification result data by using the digest, and further, the verification server authenticates the public key at a certificate center, and generating a digital certificate, attaching the digital certificate except the digital signature when sending the verification result data to the client, unlocking the digital certificate by using the public key of the certificate center after the client receives the verification result data, obtaining the public key of the verification server, further decrypting the abstract, and checking the received verification result data.
For example, a user name and a password are input at a client, a login button is clicked to log in, a system homepage is entered after the login is completed, the above process is analyzed, and 4 verification operations are performed:
the 1 st time, the user name is entered. The webpage operation information generated by the client is 'input operation generated on a user name webpage element', and additionally comprises input data content, new webpage operation process recording data is generated at the client according to the change of webpage snapshot content data after the input is completed, a message abstract algorithm is used for generating a message abstract for the new webpage operation process recording data, and the data are combined to generate operation process verification data; after receiving the data, the verification server synchronously executes input operation according to the input content in the verification execution running environment, generates new webpage operation process record data in the verification execution running environment, generates a message abstract for the new webpage operation process record data, compares the message abstract with a message abstract contained in the to-be-verified data content in the operation process verification data, and if the message abstract and the message abstract are the same, the verification is passed;
at 2 nd time, a password is entered. The mode of generating the verification data of the operation process and the verification process executed by the verification server are basically the same as the 1 st time;
and 3, logging in. The webpage operation information generated by the client is that 'clicking operation is performed on a login button, a webpage login request is sent to the server', the mode of generating operation process verification data and the verification process executed by the verification server are basically the same as those of the 1 st time and the 2 nd time, it needs to be noted that the sent webpage operation information data can contain the request content sent by the client to the service server, and preferably, the verification server verifies the content of the request according to the request information received by the service server;
and 4, loading the webpage after logging in, receiving webpage data returned by the service server by the client, and completing loading of the system homepage. The webpage operation generated by the client is 'receiving server response data and loading webpage', new webpage operation process record data is generated at the client according to the change of webpage snapshot content data after the webpage loading is finished, a message abstract is generated for the new webpage operation process record data, and the data are combined to generate operation process verification data; after the verification server receives the data, in the operation environment for executing verification, according to the client request received by the service server and the data content sent to the client, log-in is simulated and the logged-in homepage is loaded, in the operation environment for executing verification, new webpage operation process record data is generated, a message abstract is generated for the new webpage operation process record data, the message abstract is compared with the message abstract contained in the data content to be verified in the operation process verification data, a verification code is generated according to the comparison result, the verification code is added into the verification result and sent to the client, the client receives the verification result data, and verification code information is written into the webpage operation process record data.
With reference to the above embodiments, a principle of performing real-time verification in the present application is briefly described, where the content included in the operation process verification data, the verification manner and step in the verification server, and the processing manner of the verification result data at the client are not unique, and the present application should not be limited by the examples in this embodiment. The principle of the real-time verification is that according to operation and data generated by the client, when operation process recorded data is effectively recorded, the validity of the operation process recorded data is verified by the verification server, so that the client can be prevented from tampering webpage data, forging server requests and the like, and the generated webpage operation process recorded data can be used as evidence.
In a possible implementation scenario, the recorded data of the web page operation process further includes an operating environment of the web page, a browsing operation of the web page, and browsing status information of the web page, as shown in fig. 5, the steps of:
s501, recording the running environment information of the webpage and generating webpage running environment data;
s502, acquiring the contained data content or the change of the webpage data content based on the webpage snapshot;
s503, monitoring and recording browsing operation and browsing state information of the webpage, and recording corresponding time information;
and S504, storing the acquired data in a structured mode, and generating webpage operation process record data.
According to the steps, when the operation process of the webpage is recorded and executed, S501, the information of the running environment of the webpage is recorded, the recorded information is beneficial to providing information support for judging and setting the running environment of the playback when the playback is executed, and the running environment of the webpage comprises browser information, viewport size and the like. In the process of webpage operation, steps S502 and S503 are executed, and based on the webpage operation process, webpage data content and its changes, browsing operation of the webpage, browsing state information of the webpage and corresponding time information are collected, and the time information is used for calculating corresponding execution time in the playback process. S502 collects data content included in the web page snapshot or changes in the web page data content, for example, changes in the DOM of the web page in the web page operation process are monitored by the MutationObserver based on changes in the DOM of the web page in the web page operation process, and web page DOM change information is generated; the browsing operation of the web page in S503 is a web page operation that does not cause a change in the data content of the web page, such as a user cursor movement, a cursor change, a page sliding, a content change in a web page control, a viewport size change, and the like, and the browsing state information of the web page in S503 is related information of the web page in a certain browsing state, such as a cursor position, a cursor state, a window size, page position information, and the like. Finally, the final web page operation procedure record data is generated by S504.
In the above embodiment, all elements in the process of the web page operation are completely recorded, and the web page operation process recording data is generated, so that complete data support is provided for the playback of the web page operation process.
In a possible implementation scenario, various data collected in the web page operation process are structurally stored to generate web page operation process record data, and a message digest is generated for the web page operation process record data, as shown in fig. 6, the steps are as follows:
s601, performing structured storage on one or more of key frame data 6001 of web page record data, web page content change data 6002, resource file data 6003 related to web page content, operation process verification data 6004, operation process verification result data 6005, web page running environment data 6006, and web page browsing operation and browsing state record data 6007, to generate web page operation process record data 6008;
s602, generating a message abstract for the data in the webpage operation process recorded data 6008 by adopting a message abstract algorithm, wherein the message abstract record is a webpage operation process recorded data message abstract 6009;
s603, store message digest web page operation process record data message digest 6009.
According to the embodiment, data in the webpage operation process are collected to generate webpage operation process record data, a message abstract is generated for the webpage operation process record data, and the message abstract of the webpage operation process record data is used as evidence of the webpage operation. It should be noted that, the above acquisition of the data of the web page operation process, the generation and storage of the data of the web page operation process record, and the generation and recording of the abstract need to be completed at the client. In addition, the data used for generating the web page operation process recording data in S601 includes, but is not limited to, one or more of 6001 to 6007. S602 generates a message digest for the data 6008, which includes generating a message digest for the entire data 6008, generating a message digest according to the partial data contained therein, generating a message digest step by step according to the data contained therein, and so on. The message digest stored in S603 is used to identify the current webpage operation process and verify the consistency of the data recorded in the webpage operation process, the storage mode includes, but is not limited to, printing, local storage, server storage, third-party storage, block chain storage, and the like, preferably, S603 records the message digest, and records a digest algorithm and a calculation step corresponding to the generation of the message digest.
According to the embodiment provided by the embodiment, the record data and the message abstract are generated in the 'transaction area' of the two parties, so that the fairness and the openness of the record of the webpage operation process are reflected, and finally, both the webpage operator and the provider can obtain effective operation evidence when the webpage operation process is finished.
In another possible implementation scenario of the present application, according to the generation process of the web page operation process record data, after changing the web page operation process record data each time, a message digest is generated for the current web page operation process record data, and according to the message digest generated each time, a digest history record is recorded and generated, as shown in fig. 7, the detailed steps are as follows:
s701, recording the change data to the webpage operation process record data when the webpage operation process record data are changed;
s702, generating a message abstract;
and S703, adding the message digest to a digest history record.
According to the above implementation steps, the change of the web page data in S701 corresponds to various changes in web page operation, such as web page operation, server interaction, web page program operation, and the like. S702 generates message digests corresponding to the webpage operation process record data in each operation state, namely, generates operation evidences for each operation state, and each message digest is generated on the basis of the previous message digest, thereby being beneficial to generating the operation evidences which cannot be tampered. Optionally, after the message digest is generated each time, the generated message digest is added to the recorded data of the webpage operation process, so that the recorded data and the data for verification are combined, which is beneficial to fixing the operation evidence. S703 adds the message digest to a digest history that can be used to verify each operation step and the web page data.
According to the above embodiment, each operating state corresponds to a message digest, wherein the generation of each message digest is based on its previous message digest, thereby generating proof of operation that is not tamperproof throughout the process.
In another possible implementation scenario of the present application, a message summary generated by the recorded data of the current web page operation process is displayed on a web page operation interface, and an operation user is required to perform reading according to the content of the message summary or the related content thereof, as shown in fig. 8, the detailed steps are as follows:
s801, displaying a message abstract generated by the record data of the current webpage operation process on a webpage operation interface;
s802, the operation user reports and reads according to the content of the message abstract or the content related to the message abstract;
