Detailed Description

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

Fig. 1 is a schematic view of an application scenario of a backtracking method of user behavior according to one or more embodiments of the present specification, and as shown in fig. 1, the scenario includes: the system comprises a business client, a backtracking server and a block chain system; the service client may be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer, or the like (only the mobile phone is shown in fig. 1); the backtracking server side can be an independent server or a server cluster consisting of a plurality of servers; the blockchain system includes at least one blockchain node (only one is shown in fig. 1) accessing a blockchain, and data such as service record information of a user is stored in the blockchain.

Specifically, when a first user needs to handle a target service, a service client of the first user is operated to provide service data; the method comprises the steps that a service client side obtains an event triggered by the operation behavior of a first user in a current page corresponding to a target service; if the acquired event is determined to be a service processing event of the target service, page change information of the determined current page, which changes based on the operation behavior, is stored in a specified storage area; if the obtained event is determined to be a buried point event, generating behavior log data of the operation behavior; and if the acquired event is determined to be a submission event of the target service, sending the generated behavior log data to a backtracking server. The backtracking server receives behavior log data sent by the service client and acquires corresponding page change information from a specified storage area; and generating service record information of the first user about the target service according to the behavior log data and the page change information, and storing the service record information into a block chain so as to perform backtracking related processing of the operation behavior of the first user based on the behavior log data, the page change information and the service record information.

It should be noted that the backtracking server may be a blockchain node of the access blockchain, and when the backtracking server is not a blockchain node of the access blockchain, the scenario may further include a first blockchain node of the access blockchain (not shown in fig. 1); correspondingly, after the backtracking server generates the business record information, sending a storage request to the first block link node according to the business record information; the first block chain link point stores the service record information into the block chain according to the storage request.

Therefore, when a user transacts business online through the business client, the behavior log data of the user is generated, and the page change information of the page, which changes based on the operation behavior of the user, is recorded, so that after the business transaction is completed, the corresponding operation behavior of the user can be described based on the behavior log data, and the page and the change situation of the page, which is seen by the user in the business transaction process and is based on the operation behavior of the user, can be traced back based on the page change information; therefore, the problems of responsibility removal and the like caused by difficulty in restoring the service handling process when service disputes occur are solved; meanwhile, only behavior log data and page change information are generated, and a screen recording mode is not adopted to record the whole flow, so that the lightweight data recording and storage are realized on the basis of ensuring that the operation behaviors of a user can be traced, and the data storage cost is reduced. Moreover, the business record information is stored in the block chain, and based on the non-tamper property of the block chain, the authenticity and the validity of the business record information are ensured, and a reliable verification basis is provided for the real and effective backtracking of the user operation behavior.

Fig. 2 is a flowchart illustrating a method for backtracking user behavior according to one or more embodiments of the present disclosure, where the method in fig. 2 can be performed by the backtracking server in fig. 1, and as shown in fig. 2, the method includes the following steps:

step S102, receiving behavior log data of a first user in a page corresponding to a target service, which is sent by a service client; the behavior log data is generated based on a buried point event triggered by the operation behavior of the first user in a page corresponding to the target service;

specifically, a service client corresponding to a target service is installed in a terminal device of a first user, where the service client may be an independent client program (APP), a web Application (i.e., an Application program running on the basis of a web page), an applet embedded in another Application program, or the like. When a first user needs to handle a target service, the service client side of the first user is operated to provide service data in each page corresponding to the target service. As shown in fig. 3, a service client obtains an event triggered by an operation behavior of a first user in a current page corresponding to a target service; if the acquired event is determined to be a service processing event of the target service, page change information of the determined current page, which changes based on the operation behavior, is stored in a specified storage area; if the obtained event is determined to be a buried point event, generating behavior log data of the operation behavior; and if the acquired event is determined to be a submission event of the target service, sending the generated behavior log data to a backtracking server.

Wherein, the operation behavior of the user is click, double click, sliding, inputting, deleting, etc. The target business is insurance business, financing business, mutual aid business, commodity purchasing business and the like. Business processing events such as information input events, button clicking events, protocol signing events, page access events and other events related to the handling of target business; the buried point event can be an event subset of the transaction events, and is an event triggered by key operation behaviors of the user about the target service, for example, the target service is an insurance service, and the buried point event can be an access event of a page, a signing event of an insurance agreement, an input event of an insurance duration, an input event of an insurance amount, and the like. The buried point event can be set in practical application according to the requirement. The behavior log data is used for describing a corresponding operation behavior, and includes page identification information of a corresponding page, operation information of a corresponding operation behavior, and the like, where the operation information includes one or more of element identification information of a page element of an operation, operation time, operation type (e.g., clicking, sliding, inputting, and the like), operation content (e.g., input information, selected information, and the like), so that a corresponding operation can be described according to the behavior log data, for example, a certain operation is performed on a page element corresponding to certain element identification information at a certain time to input or select certain information, and the like.

Step S104, acquiring page change information generated by a service processing event triggered by the operation behavior of the first user in a page corresponding to the target service from the designated storage area;

the page change information includes, for example, CSS (Cascading Style Sheets) Style, DOM (text Object Model) structure, and the like of a page element that changes based on the operation behavior of the first user. The CSS can define the display modes of all page elements in the page, such as texts, backgrounds, frames, intervals among the page elements and the like; each CSS selector corresponds to a page element. The DOM may cause dynamic changes to the page, such as dynamically hiding or displaying page elements, changing attributes of page elements, adding page elements, and the like. Each DOM node in the DOM structure corresponds to one page element in the page. Since CSS styles and DOM structures are well known technical means to those skilled in the art, they will not be described in detail here. By acquiring the page change information, the corresponding page and the change of the page can be restored based on the CSS style and the DOM structure when the operation behavior of the user is backtracked.

And step S106, generating service record information of the first user about the target service according to the behavior log data and the page change information, and storing the service record information into the block chain as backtracking processing information.

In one or more embodiments of the present description, when receiving behavior log data sent by a service client, a backtracking server obtains corresponding page change information from a specified storage area, generates service record information of a first user about a target service according to the behavior log data and the page change information, and stores the service record information in a block chain. Therefore, by generating behavior log data of the user and recording page change information of the page, which changes based on the operation behavior of the user, after the business transaction is completed, the corresponding operation behavior of the user can be described based on the behavior log data, and the page and the change situation of the page, which is seen by the user in the business transaction process, based on the page change information are traced back; therefore, the problems of responsibility removal and the like caused by difficulty in restoring the service handling process when service disputes occur are solved; meanwhile, only behavior log data and page change information are generated, and a screen recording mode is not adopted to record the whole flow, so that the lightweight data recording and storage are realized on the basis of ensuring that the operation behaviors of a user can be traced, and the data storage cost is reduced. Moreover, the business record information is stored in the block chain, and based on the non-tamper property of the block chain, the authenticity and the validity of the business record information are ensured, and a reliable verification basis is provided for the real and effective backtracking of the user operation behavior.

Considering that the object Storage service (oss) object Storage is a massive, secure, low-cost, highly reliable cloud Storage service, has platform independence, and can be accessed from any position of the internet. Based on this, in order to reduce the amount of data transmitted between the service client and the backtracking server and increase the data transmission rate, as shown in fig. 3, in one or more embodiments of the present specification, the service client stores the determined page change information in a specified OSS storage space; accordingly, step S104 may include: and acquiring page change information generated by a service processing event triggered by the operation behavior of the first user in a page corresponding to the target service from the specified OSS storage space.

Furthermore, in order to increase the rate of obtaining page change information by the backtracking server and facilitate management of the page change information, in one embodiment of the present disclosure, the service client stores the determined page change information in a file form in a designated storage area in association with the page identification information of the corresponding page; and generating behavior log data according to the page identification information of the corresponding page based on the embedded point event acquired in each page corresponding to the target service. Accordingly, step S104 may include: acquiring a file which is stored in a related way from a specified storage area according to page identification information in the received behavior log data; the file includes page change information of the corresponding page.

It should be noted that each page may correspond to one or more files, and therefore, the backtracking server only needs to query the associated files from the designated storage area according to the page identification information, rather than querying each piece of page change information one by one, so that the query efficiency can be improved; and compared with the management of each piece of page change information, the management of the file is more convenient and easier, and the loss and omission of the page change information are not easy to cause. The process of the service client saving the page change information is detailed later.

Generally, in the service transaction process, the service end generates a corresponding service certificate to prove that the user successfully transacts the corresponding service, and provides the user with subsequent services based on the service certificate. In order to enable the behavior log data and the page change information to be associated with the service credential of the first user about the target service, so as to trace back the operation behavior of the first user about the target service, as shown in fig. 3, after receiving the behavior log data, the trace-back server further sends the generated service handling identification information of the first user about the target service to the service client, so that the service client sends a service handling request to the service server based on the service handling identification information; therefore, the backtracking server receives the certificate identification information and the service handling identification information sent by the service server and stores the certificate identification information and the service handling identification information in association with the behavior log data. Specifically, step S102 may be followed by step S103-2 and step S103-4 as follows:

step S103-2, generating service handling identification information of the first user about the target service, and sending the service handling identification information to a service client;

step S103-4, receiving service transaction identification information sent by a service server corresponding to the target service and certificate identification information of a service certificate of the first user about the target service; and storing the received service handling identification information and the received certificate identification information in a specified database in a way of being associated with the behavior log data.

In order to improve the business handling efficiency, in one or more embodiments of the present specification, different businesses correspond to different business servers; for example, the car insurance service corresponds to a car insurance server, the accident insurance service corresponds to an accident insurance server, and the like. Because the business client can provide the handling of various businesses, the business client can correspond to a plurality of business servers, such as a vehicle insurance server, an accident insurance server and the like.

Specifically, when the backtracking server receives the behavior log data, service transaction identification information of the first user about the target service is generated according to a preset generation mode to represent one-time transaction of the target service. And the backtracking server stores the generated service handling identification information and the received log data in a specified database in a correlation manner, and sends the service handling identification information to the service client. And after receiving the service handling identification information sent by the backtracking server, the service client sends a service processing request to the service server corresponding to the target service according to the service handling identification information and the acquired service data submitted by the first user. And after receiving the service processing request, the service server performs service processing according to the service data to generate a service certificate, and sends the certificate identification information of the determined service certificate and the service handling identification information included in the service processing request to the backtracking server. After receiving the certificate identification information and the business handling identification information sent by the business server, the backtracking server matches the business handling identification information with the business handling identification information in the designated database, and stores the certificate identification information and the successfully matched business handling identification information in the designated database in an associated manner, so that the behavior log data, the business handling identification information, the certificate identification information and the like are associated.

In order to improve the service processing efficiency, in one or more embodiments of the present specification, a generation server for generating a service credential may be further configured, and correspondingly, when the service server receives a service processing request sent by a service client, perform service processing (such as data verification, user identity verification, and the like) according to service data, and after the service processing is successful, send a credential generation request to the generation server according to the service data and service transaction identification information; and the generation server generates a corresponding service certificate according to the received certificate generation request, and sends the determined certificate identification information and the service handling identification information to the backtracking server. The generation mode of the business certificate can be set in practical application according to the requirement.

It is noted that step S103-2 and step S103-4 may also be performed after step S104, or may also be performed simultaneously with step S104.

Therefore, by generating the service handling identification information, acquiring the certificate identification information of the first user about the service certificate of the target service based on the service handling identification information, and storing the certificate identification information, the service handling identification information and the behavior log data in an associated manner, the corresponding behavior log data can be quickly inquired when the subsequent backtracking processing is performed on the operation behavior of the first user about the target service.

Further, in order to restore a page change process more truly during backtracking processing, in one or more embodiments of the present specification, the service client obtains initial page information of a page each time a new page corresponding to a target service is opened based on an operation behavior of a first user, and stores the initial page information and the determined page identification information in a specified storage area, such as a specified OSS storage space in an associated manner. Accordingly, step S104 may include: and acquiring initial page information and page change information of a page corresponding to the target service from the specified storage area.

Further, in order to quickly acquire corresponding page change information during backtracking processing and enable an initial state of each page to be presented and enable change conditions of multiple pages to be presented continuously, such as in a video form, during backtracking of a page based on a change process of an operation behavior of a user, in one or more embodiments of the present specification, as shown in fig. 3, a backtracking server generates a service backtracking file based on the acquired initial page information and page change information, so as to continuously present the change conditions of the page based on the service backtracking file. Specifically, step S104 may be followed by the following step S105-2 to step S105-6:

step S105-2, the obtained initial page information and the page change information are combined to obtain a service backtracking file of the first user about the target service;

specifically, the files acquired from the designated storage area according to the page identification information are merged to obtain a service backtracking file of the first user about the target service.

Step S105-4, determining file identification information of the service backtracking file;

the determination rule of the file identification information may be set in practical application as needed, and this is not specifically limited in this specification.

And step S105-6, storing the business backtracking file and the file identification information into a storage area in an associated manner, and storing the file identification information and the business handling identification information into a specified database in an associated manner.

For example, the business backtracking file and the file identification information are stored in a designated OSS storage area in an associated manner.

By generating the service backtracking file, when backtracking processing is performed, the initial state of each page can be continuously restored based on the initial page information (such as the initial CSS pattern of the page element, the initial DOM mechanism, and the like) in the service backtracking file, and each change condition of the page can be restored based on the page change information (such as the CSS pattern of the page element and/or the update information of the DOM node, which are changed based on the operation behavior of the user). Therefore, related backtracking personnel can perform complete and continuous backtracking on each page seen by the first user in the process of transacting the target business in the form of browsing videos, changes of the page based on each operation behavior of the user and the like. Moreover, the file identification information and the service handling identification information are stored in a correlated mode, so that the service backtracking file can be further correlated with the certificate identification information of the service certificate of the first user, and the service backtracking file can be quickly and accurately inquired when the service is backtracked.

Corresponding to steps S105-2 to S105-6, step S106 may include the following step S106-2:

and S106-2, generating service record information of the first user about the target service according to the behavior log data and the service backtracking file, and storing the service record information into the block chain as backtracking processing information.

Specifically, hash processing is performed on the behavior log data and the service backtracking file according to a preset mode to obtain a hash value; the hash value and the certificate identification information are recorded in an associated mode, and the recorded information is determined as service record information of the first user about the target service; and storing the service record information into the block chain.

Considering that currently for some businesses, third party authorities have regulatory requirements for the business to avoid false business transactions. In order to enable the service provider to provide corresponding backtracking data in the supervision process, the third party authority is enabled to perform backtracking processing on the service handling process. In one or more embodiments of the present specification, as shown in fig. 3, after the backtracking server stores the service record information in the blockchain, the backtracking server may further send service backtracking data and credential identification information generated based on the behavior log data and the service backtracking file to the service provider of the target service; for example, the target service is an insurance service, the service provider may be an insurance company, and the like. Specifically, step S106 may be followed by steps S108 to S110 as follows:

step S108, determining the behavior log data and the service backtracking file as service backtracking data of the first user about the target service;

specifically, the behavior log data and the service backtracking file are packaged to obtain service backtracking data of the first user about the target service.

Step S110, the service backtracking data and the credential identification information are sent to a service provider of the target service, so that the service provider performs a supervision process based on the service backtracking data when receiving a service supervision request of the first user about the target service, which is sent by a third party authority.

When the service provider receives a service supervision request, about a target service, of a first user, sent by a third-party authority, service backtracking data is sent to the third-party authority, so that the third-party authority backtracks the operation behavior of the first user based on the service backtracking data.

In order to ensure the security of data transmission, in one or more embodiments of the present specification, the trace-back server sends the service trace-back data and the credential identification information to the service provider of the target service through SFTP (secure File Transfer Protocol).

Further, as shown in fig. 3, when the third party authority receives the service backtracking data sent by the service provider, in order to ensure the authenticity of the service backtracking data, the third party authority may further send a verification request to the backtracking server according to the service backtracking data and the credential identification information, so that the backtracking server performs verification processing on the block chain. Specifically, step S110 may be followed by steps S112 to S116 as follows:

step S112, receiving a verification request sent by a third party authority, wherein the verification request comprises service backtracking data to be verified and certificate identification information;

step S114, according to a preset mode, carrying out hash processing on the service backtracking data to be verified to obtain a hash value to be verified; inquiring the associated service record information from the block chain according to the certificate identification information included in the verification request;

step S116, if the hash value to be verified is determined to be matched with the hash value in the inquired business record information, the verification result information representing that the verification is passed is sent to the third party authority.

Further, if the hash value to be verified is determined not to be matched with the hash value in the inquired business record information, verification result information representing that the verification fails is sent to the third party authority.

In one or more embodiments of the present specification, the steps S114 and S116 may further include, in consideration of the intelligent contracts having the characteristics of automatic execution and no user intervention: calling a first intelligent contract in the block chain, and performing hash processing on the service backtracking data to be verified according to a preset mode based on the first intelligent contract to obtain a hash value to be verified; inquiring related business record information from the block chain according to the certificate identification information included in the verification request, and matching the hash value to be verified with the hash value in the inquired business record information to obtain a matching result; and if the matching result is determined to be successful, sending verification result information representing that the verification is passed to a third party authority.

Therefore, verification processing is carried out based on the service record information in the block chain, and the verification accuracy is improved.

Further, when the third party authority receives the verification result information which is sent by the backtracking server and passed by the characterization verification, the business backtracking processing can be performed based on the business backtracking data, for example, the business backtracking file in the business backtracking data is operated through the terminal equipment, so that each page seen by the user and the change condition of each page based on the operation behavior of the first user are presented based on the form of video. And displaying the description information of the corresponding operation behavior of the first user based on the behavior log data in the display interface of the video, or displaying a plurality of selection controls in an option mode, and displaying the description information of the corresponding operation behavior according to the corresponding behavior log data when the selection operation of the user on a certain selection control is acquired. In the backtracking process, the display form of the backtracking page can be set in practical application as required, and the specification is not limited specifically.

Further, considering that after the business transaction is completed and business disputes occur, the relevant users have a backtracking requirement for business transaction, as shown in fig. 3, in one or more embodiments of this specification, the backtracking server may further combine the query request sent by the querying user and send corresponding business backtracking files and behavior log data to the querying user. Specifically, step S106 may be followed by steps S118 to S122 as follows:

step S118, receiving a query request sent by a query user; wherein the query request includes credential identification information;

the query user may be a first user, a customer service user of the target service, a user of a related organization performing dispute handling, or the like.

Step S120, acquiring associated behavior log data and file identification information from a specified database according to the certificate identification information; acquiring a related service backtracking file from a designated storage area according to the acquired file identification information;

step S122, sending the obtained service backtracking file and the behavior log data to the querying user, so that the querying user performs backtracking processing on the operation behavior of the first user based on the service backtracking file and the behavior log data.

The process of the query user for backtracking the operation behavior of the first user based on the service backtracking file and the behavior log data can be referred to the backtracking process of the third-party authority, and repeated parts are not described herein again.

Therefore, the operation behavior of the first user can be backtracked based on the behavior log data and the page change information through the behavior log data and the page change information generated by the service client according to the operation behavior of the first user in the page corresponding to the target service, and the handling process of the target service of the first user is restored, so that the problems of liability dumping and the like caused by difficulty in restoring the service handling process when service disputes occur are solved; meanwhile, only behavior log data and page change information are generated, and a screen recording mode is not adopted to record the whole flow, so that the lightweight data recording and storage are realized on the basis of ensuring that the operation behaviors of a user can be traced, and the data storage cost is reduced.

It should be noted that fig. 3 is only used for illustration and not for limitation, and the execution sequence of some operations may be interchanged and may be executed simultaneously.

The above is related to the processing procedure of the one-time transaction completed service, and it is considered that in practical application, some services are not completed at one time, but include a plurality of sub-services which are performed intermittently. For example, for car insurance services, it may include an enquiry sub-service, a quote sub-service, an insurance sub-service, etc.; namely, the user operates the business client to initiate a request for price inquiry; after receiving the inquiry request, the insurance company carries out market research and quotation processing, and gives out quotation results after a few days; after inquiring the quotation result at the service client, the user has a period of several days, and operates the service client to carry out insurance application processing when finally deciding the insurance application. In order to completely trace back the operation behavior of the first user when handling the first service, in one or more embodiments of the present specification, each sub-service is associated. Specifically, when the target service is a sub-service of the first service, the aforementioned step S103-4 may include the following steps S103-42 and S103-44:

step S103-42, when the target service is not the last sub-service of the first service, receiving service handling identification information and sub-service identification information of the target service sent by a service server corresponding to the target service; storing the received service handling identification information and sub-service identification information in a designated database in a manner of being associated with behavior log data;

step S103-44, when the target service is the last sub-service of the first service, receiving service handling identification information, sub-service identification information of the target service and certificate identification information sent by a service server corresponding to the target service; and storing the received service handling identification information, sub-service identification information and certificate identification information in a specified database in a way of being associated with the behavior log data.

Specifically, when receiving behavior log data sent by a service client, a backtracking server generates service handling identification information of a first user about a target service so as to represent one-time handling of the target service; and storing the behavior log data and the generated service handling identification information into a specified database in a correlated manner, and sending the generated service handling identification information to a service client. And the service client sends a service processing request to the service server of the target service according to the service processing identification information and the acquired service data (such as inquiry data of the car insurance) of the target service submitted by the first user. And after receiving the service processing request, the service server side determines that the current target service is the sub-service of the first service and is not the last sub-service based on the service data, generates sub-service identification information of the target service, and sends the sub-service identification information and the service processing identification information included in the service processing request to the backtracking server side. And when the backtracking server receives the sub-service identification information and the service handling identification information, matching the service handling identification information with the service handling identification information in the specified database, and storing the sub-service identification information and the successfully matched service handling identification information in the specified database in an associated manner. And generating a service backtracking file of the first user about the target service in the manner described in the foregoing steps S105-2 to S105-6, storing the file identification information, the service transaction identification information and the sub-service identification information in association with a specified database, and storing the service backtracking file and the file identification information in association with a specified storage area. Further, after the service server receives the service processing request, when it is determined that the current target service is a sub-service of the first service and is the last sub-service based on the service data, generating sub-service identification information of the target service and generating a service certificate of the first user about the first service, and sending the service handling identification information, the sub-service identification information and the certificate identification information included in the service processing request to the backtracking service terminal; and the backtracking server performs matching processing according to the service handling identification information, and stores the received sub-service identification information and the certificate identification information in association with the successfully matched service handling identification information into a specified database.

Further, in order to fully trace back the operation behavior of the first user with respect to the first service, when the target service is the last sub-service of the first service, the method further includes:

determining the sub-service identification information of each sub-service included in the first service, and acquiring file identification information stored in a relevant manner from a specified database according to the determined sub-service identification information; acquiring a service backtracking file which is stored in a related way from a specified storage area according to the acquired file identification information; merging the obtained service backtracking files to obtain a target backtracking file of the first user about the first service; and storing the file identification information of the determined target backtracking file and the target backtracking file into a specified storage area in an associated manner, and storing the file identification information of the determined target backtracking file and the certificate identification information into a specified database in an associated manner.

Optionally, when the service server determines that the current target service is a sub-service of the first service and is the last sub-service based on the service data, the service server sends the recorded sub-service identification information, the certificate identification information and the service handling identification information of each associated sub-service to the backtracking service server; correspondingly, the determining sub-service identification information of each sub-service included in the first service includes: and determining the sub-service identification information sent by the service server as the sub-service identification information of each sub-service included in the first service. Or when the service server determines that the current target service is a sub-service of the first service and is the last sub-service based on the service data, the service server acquires the sub-service identification information of each sub-service included in the first service to which the recorded target service belongs after transmitting the sub-service identification information, the certificate identification information and the service handling identification information of the target service to the backtracking service server, and transmits the acquired sub-service identification information to the backtracking service server; correspondingly, the determining sub-service identification information of each sub-service included in the first service includes: and determining the received sub-service identification information sent by the service server as the sub-service identification information of each sub-service included in the first service.

Further, corresponding to the foregoing steps S103-42 and steps S103-44, step S106 may include the following step S106-4:

step S106-4: and if the received voucher identification information is determined, generating service record information of the first user about the target service according to behavior log data and page change information corresponding to each sub-service of the first service, and storing the service record information into a block chain.

Specifically, acquiring associated behavior log data from a specified database according to the determined sub-service identification information of each sub-service included in the first service; according to a preset mode, carrying out hash processing on the acquired behavior log data and the generated target backtracking file to obtain a hash value; and recording the obtained hash value and the certificate identification information in an associated manner, determining the recorded information as the service record information of the first user about the target service, and storing the service record information into a block chain.

Therefore, when the first service comprises a plurality of sub-services which are performed discontinuously and the target service is one of the sub-services of the first service, the service backtracking file is generated according to the manner described in the foregoing steps S105-2 to S105-6, and the sub-service identifier sent by the service server is received, so that the service backtracking file of the corresponding sub-service can be obtained according to the sub-service identifier, the target service backtracking file is generated according to the obtained service backtracking file of each sub-service, the operation behavior of the first user in each sub-service can be backtracked based on the target service backtracking file, and the integrity of backtracking is ensured.

On the basis of the same technical concept, one or more embodiments of the present specification further provide another method for tracing user behavior, fig. 4 is a schematic flow diagram of another method for tracing user behavior provided by one or more embodiments of the present specification, and the method in fig. 4 can be executed by the service client in fig. 1; as shown in fig. 4, the method comprises the steps of:

step S202, acquiring an event triggered by the operation behavior of a first user in a current page corresponding to a target service;

step S204, if the acquired event is determined to be a service processing event of the target service, page change information of the determined current page, which changes based on the operation behavior of the first user, is stored in a specified storage area;

step S206, if the acquired event is determined to be a buried point event, behavior log data of the operation behavior of the first user is generated;

step S208, if the acquired event is determined to be a submission event of the target service, sending the generated various behavior log data to a backtracking server; and the backtracking server generates service record information of the first user about the target service according to the behavior log data and the page change information in the designated storage area and stores the service record information into the block chain as backtracking processing information.

In one or more embodiments of the present specification, the service client generates corresponding behavior log data and/or stores corresponding page change information based on the obtained event, and sends the generated behavior log data to the backtracking server based on the submission event, so that the backtracking server performs backtracking related processing of the operation behavior of the first user based on the behavior log data, the obtained page change information, and the service record information in the block chain. Therefore, by generating behavior log data of the user and recording page change information of the page, which changes based on the operation behavior of the user, after the business transaction is completed, the corresponding operation behavior of the user can be described based on the behavior log data, and the page and the change situation of the page, which is seen by the user in the business transaction process, based on the page change information are traced back; therefore, the problems of responsibility removal and the like caused by difficulty in restoring the service handling process when service disputes occur are solved; meanwhile, only behavior log data and page change information are generated, and a screen recording mode is not adopted to record the whole flow, so that the lightweight data recording and storage are realized on the basis of ensuring that the operation behaviors of a user can be traced, and the data storage cost is reduced. Moreover, the business record information is stored in the block chain, and based on the non-tamper property of the block chain, the authenticity and the validity of the business record information are ensured, and a reliable verification basis is provided for the real and effective backtracking of the user operation behavior.

Considering that the user often has not only the operation behavior related to the target service (such as inputting service data) in the service transaction process, but also may have other operation behaviors unrelated to the transaction of the target service, such as clicking operation performed on a blank area of a page or fixed characters and pictures and the like by the user in order to light up the screen of the terminal device. In order to enable the service client to accurately obtain the service processing event related to the target service triggered by the operation behavior of the user, in one or more embodiments of the present specification, element identification information of a page element corresponding to the service processing event is preset, and accordingly, the step S204 of determining that the obtained event is the service processing event of the target service includes: and if the acquired event is determined to carry the preset element identification information, determining that the acquired event is a service processing event of the target service.

Similarly, the event determined to be a buried point event in step S206 includes: and if the acquired event is determined to carry the preset embedded point identification information, determining that the acquired event is the embedded point event.

It should be noted that when the acquired event carries preset element identification information and carries a buried point event, the service processing event and the buried point event are determined to be acquired, the determined page change information is stored in a specified storage space, and corresponding behavior log data is generated.

In order to effectively restore the page viewed by the user during the backtracking process, in one or more embodiments of the present specification, the page change information includes a CSS style of a corresponding page element and/or update information of a DOM node. Specifically, step S204 may include the following steps S204-2 and S204-4:

step S204-2, if the acquired event is determined to be a service processing event of the target service, determining whether an updated target CSS pattern exists in the CSS patterns corresponding to the current page, and determining whether an updated target DOM node exists in the DOM structure corresponding to the current page;

and step S204-4, determining the target CSS style and/or the update information of the target DOM node as the page change information of the current page changed based on the operation behavior of the first user, and storing the page change information into a specified storage area.

Specifically, when the first user operates a page element in the current page, for example, inputting information in an input box, clicking a determination button, and the like, the CSS style corresponding to the page may be changed, or both the CSS style and the DOM structure corresponding to the page may be changed, and the CSS style and the DOM structure are automatically updated based on the user operation. The method comprises the steps that a service client monitors a CSS style and a DOM structure of a current page through a specified script, when the service client determines that an obtained event is a service processing event of a target service and monitors that the CSS style and the DOM structure of the current page have corresponding updated target CSS style and/or target DOM nodes through the specified script, the page change information of the page based on the operation behavior of a first user is determined according to the updated information of the target CSS style and/or the target DOM nodes.

In order to clarify the corresponding relationship between the page change information and the page, in one or more embodiments of the present specification, before step S204, the method further includes: determining page identification information of a current page;

accordingly, step S204 may include the following step S204-6:

step S204-6: and if the acquired event is determined to be the service processing event of the target service, page change information of the determined current page, which changes based on the operation behavior of the first user, and the determined page identification information are stored in a specified storage area in an associated manner.

Furthermore, in order to facilitate the backtracking of the server side to query the page change information, in one or more embodiments of the present specification, the page change information is stored in a file form; correspondingly, the step S204-6 of saving the page change information of the determined current page, which changes based on the operation behavior of the first user, in association with the determined page identification information to the specified storage area includes:

determining whether a preset file creating condition is met; if so, creating a file, storing the determined page change information into the created file, and storing the created file and the page identification information into a specified storage area in an associated manner; if not, acquiring the associated target file from the storage area according to the page identification information, and storing the page change information into the target file.

Wherein the preset file creation condition may include one or more of the following: the obtained service processing event is an access event of a page which is not accessed, the size of data stored in a current file reaches a preset size, the time interval from the last obtained page change information exceeds a preset time length, and the like.

Further, in order to display an initial complete page viewed by a user during service backtracking, in one or more embodiments of the present specification, the method further includes:

acquiring initial page information of the current page, and storing the acquired initial page information and the page identification information into a storage area in an associated manner. Specifically, the initial CSS style and the initial DOM structure of the current page are obtained from the specified position, the obtained initial CSS style and the obtained initial DOM structure are determined as the initial page information of the current page, and the initial page information and the page identification information are stored in the storage area in an associated mode.

Considering that the object Storage service (oss) object Storage is a massive, secure, low-cost, highly reliable cloud Storage service, has platform independence, and can be accessed from any position of the internet. Based on this, in one or more embodiments of the present specification, saving, in step S204, page change information that the determined current page changes based on the operation behavior of the first user to a specified storage area includes: and saving the determined page change information of the current page, which changes based on the operation behavior of the first user, to a specified OSS storage space.

Further, in order to describe some key operation behaviors of the first user during the backtracking process, in one or more embodiments of the present specification, the step S206 may include the following steps S206-2 and S206-4

Step S206-2, if the acquired event is determined to be a buried point event, determining operation information of the operation behavior of the first user; the operation information comprises one or more of element identification information, operation time, operation type and operation content of the page element of the operation;

step S206-4: and performing related recording on the determined operation information and the determined page identification information of the current page, and determining the recorded information as behavior log data of the operation behavior.

Further, after generating the behavior log data of the operation behavior, the service client may further include: storing the behavior log data into a specified cache;

correspondingly, when the service client acquires the submission event, the service client sends the behavior log data in the cache to the backtracking server, that is, the generated behavior log data is sent to the backtracking server in step S206, which may include: and sending the behavior log data stored in the cache to a backtracking server.

Furthermore, in the service handling process, the service server generates a corresponding service certificate to prove that the user successfully handles the corresponding service, and provides the user with subsequent services based on the service certificate. In order to enable the generated behavior log data and the recorded page change information to be associated with the service credential of the first user about the target service, so as to trace back the operation behavior of the first user about the target service, in one or more embodiments of the present specification, as shown in fig. 3, after the service client sends the behavior log data to the trace-back server, the service client also receives service handling identification information sent by the trace-back server. Specifically, step S206 may be followed by step S208 and step S210 of:

step S208, receiving service handling identification information of the first user about the target service, which is sent by the backtracking server;

step S210, sending a service processing request to a service server corresponding to the target service according to the service handling identification information and the acquired service data submitted by the first user, so that the service server performs service processing according to the service data, and sending the generated voucher identification information of the service voucher and the service handling identification information to the backtracking server.

In order to further understand the operation of the service client, the following description takes recording processing based on the operation behavior of the first user in the first page corresponding to the target service as an example, and may include:

when a service client acquires a page access event (the page access event is a service processing event) triggered by an operation behavior of opening a first page by a first user, determining the first page as a current page; determining page identification information of a current page, acquiring initial page information of the current page, creating a file, storing the acquired initial page change information into the created file, and storing the file and the page identification information into a specified OSS storage space in an associated manner. The service client continuously acquires an event triggered by the operation behavior of the first user in the current page, and if the acquired event is determined to be a service processing event (such as an information input event), page change information is determined; and acquiring the associated file from the specified OSS storage space according to the page identification information, and if the size of the file is determined not to reach the preset size and the residual size is not smaller than the size of the determined page change information, storing the determined page change information into the acquired file. When the service client determines that the obtained event is a buried point event, determining operation information of an operation behavior of a first user, and generating behavior log data according to the operation information and the determined page identification information; and storing the behavior log data into a specified cache, and continuously acquiring an event triggered by the operation behavior of the first user in the current page. And if the access event of the second page of the target service during the acquired event is determined, determining the second page as the current page, and continuing processing according to the mode. When the obtained event is determined to be a submitted event, sending each behavior record information stored in the cache to the backtracking server, and receiving service handling identification information sent by the backtracking server; sending a service processing request to a service server corresponding to the target service according to the received service handling identification information and the acquired service data submitted by the first user; and receiving the service processing result information sent by the service server and displaying the service processing result information.

Furthermore, considering that some users may decide not to continue transacting the service in the middle of transaction, at this time, because partial behavior log data is stored in the cache, partial page change information is also stored in the designated storage space; in order to avoid occupying a storage space for storing the data, in one or more embodiments of the present specification, the method further includes:

and if the ending event is determined to be acquired before the submission event is acquired, clearing the corresponding behavior log data in the buffer, and clearing the corresponding page change information in the designated storage space.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
