Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

Fig. 1 is an application scenario diagram of an example in the prior art, as shown in fig. 1, in an online education industry in the education technical field, a great number of courses exist in a course library, the same course includes at least one version, a seller sells access rights of the courses to a user in a manner of signing a contract, the user obtains access rights of purchased courses through signing the contract, and accesses the course library through the access rights, so that online checking of corresponding courses is realized.

Currently, after signing a contract with a user about a certain course, the user may obtain access rights about all historical versions of the course and all versions updated subsequently, for example, for use in the signed contract, to display that the purchased course is course a, and different versions of course a may include different lessons, for example, course a currently includes two versions, i.e., version 1 and version 2, respectively. In the example, the user currently signs a contract to purchase the course a, and the user has access rights to all versions of the course a, which results in inflexible management of access rights of the user, and if sellers of the course price different versions, economic losses are easily caused.

The online course contract signing method and device provided by the application are used for determining the content corresponding to each custom field in the contract template based on the user information, the first version of the first course purchased by the user and whether specific service is allowed or not, and correspondingly filling the content corresponding to each custom field into the respective definition field to generate the contract corresponding to the user and the digital signature, wherein the digital signature characterizes the access authority of the user to each version of the first course. The application limits the access right to the version of the course by generating the digital signature, so that the user can only access the purchased version of the course, and the flexibility of accessing the front line to the user can be improved, thereby avoiding the user from accessing the version of the course which is not purchased and reducing economic loss.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Example 1

Fig. 2 is a flow chart of an online course contract signing method according to an embodiment of the present application, where, as shown in fig. 2, the method includes:

Step 201, determining a contract template, user information and user requirements, wherein the contract template comprises at least one custom field, and the user requirements comprise a first version of a purchased first course and whether a specific service is allowed or not, and the specific service characterizes an updated version of the first course which is automatically purchased by a user;

Step 202, determining the content corresponding to each custom field in the contract template based on the user information and the user requirements, and correspondingly filling the content corresponding to each custom field into each definition field to generate a contract corresponding to the user and a digital signature, wherein the digital signature characterizes the access rights of the user to each version of the first course.

In connection with the scenario example, a contract template may be created from a template editor in the contract management system, including static fields and dynamic fields in the contract template, where the static fields are contract default content, such as unchangeable fields like contract numbers. The dynamic field is a custom field of the contract, and needs to be determined according to the client information and the client requirement, for example, the course title, the course scope, the price strategy, the payment terms and the like can be custom filled according to the client requirement. User requirements may be determined by customer communication, face-to-face meetings, emails, online questionnaires, or requirement collection tools, recorded by a customer relationship management (Customer Relationship Management, abbreviated CRM) system, and the online forms are used to collect and sort the customer's requirement data, ensuring the integrity and accuracy of the requirements. The course title may be based on the course purchased by the user, and the first course purchased by the user is course a, and the course title may be: "purchase treaty for course A", the specific title may be based on the actual situation; the course scope characterizes the purchased courses in the user requirements, the user requirements comprise specific services, the specific services are optional services, namely, the user can purchase the updated version of the purchased courses automatically, for example, if the first course purchased by the user is the course A, and the first version of the purchased course A is the current latest version-version 2, the course scope is the version 2 of the course A purchased by the user. If the user still wants to view the course content in the subsequent updated version, the user can select a specific service; conversely, if the user only wants to view version 2 of course a, the user may not select a particular service. The field of the price policy may be based on the user's needs, and if the user selects a particular service, the pricing at the price policy should be the sum of the prices of version 2 and the subsequent updated versions, and if the user does not select a particular service, the pricing at the price policy should be the pricing of course a of version 2. After each custom field is filled, a contract and a digital signature of the course purchased by the user can be generated, and the representation form of the digital signature can be a key pair. The digital signature characterizes the access authority of the user to the course, the digital signature can be based on the range of the course purchased by the user, and if the range of the course purchased by the user is the version 2 of the course A, the access authority corresponding to the digital signature of the user is the version 2 of the course A. The access authority of the version of the course is limited by generating the digital signature, so that the user can only access the purchased version of the course, the flexibility of accessing the front line to the user can be improved, the user is prevented from accessing the version of the course which is not purchased, and the economic loss is reduced.

Optionally, the method further comprises:

And detecting whether the version of the first course is updated, and if the version of the first course is updated and the user receives the specific service, updating the contract and the digital signature corresponding to the user.

In combination with the scenario example, the digital signature generated according to the contract can only access the version 2 purchased at the time, and for the user selecting the specific service, the user needs to access the access right of the new version, so after the version of course a is updated, the digital signature of the user needs to be updated, so that the digital signature of the user has the right of accessing the new version. For example, if the user signs a contract, the user selects the specific service from version 2 of course a, and if course a is currently updated to version 3, the course range in the contract of the user receiving the specific service may be updated to version 2 and version 3 of course a, and then the digital signature is updated, so that the digital signature has access rights to both version 2 and version 3 of course a. Based on the method provided by the example, after the version of the first course purchased by the user is updated, the user can have access to the updated version by updating the available course range and the digital signature.

Optionally, fig. 3 is a flowchart of another online course contract signing method according to the first embodiment of the present application, as shown in fig. 3, in step 202, the step of filling the content corresponding to each custom field into the respective definition field includes:

Step 301, adding the same identifier to each custom field and the corresponding content;

step 302, coding each custom field and the corresponding content to obtain a data string, wherein the data string carries an identifier before coding;

Step 303, running a pre-written script program, and filling the data string into a custom field consistent with the carried identification.

In connection with the scenario example, each dynamic field, i.e., custom field, in the same template may be numbered, such as course title number 1, course scope number 2, price policy number 3, payment terms number 4, and so on. After determining the content to be filled in of each custom field, the content to be filled in of each custom field can be added with the same content as the corresponding custom field. Such as curriculum topics: the "purchase treaty for course a" may be numbered as "purchase treaty for course a" for number 1, and similarly, if course ranges are: "version 2 of course A", the number of "version 2 of course A" may be designated as number 2, in this way, the contents of each custom field are numbered. Since the contents of the custom fields are mostly in text form, in order to automatically fill the contents of each custom field into the corresponding custom field, the contents of each custom field can be encoded first, the number after encoding is unchanged, and each encoded data string is filled into the same custom field according to a pre-written script program, so that the automatic filling efficiency is improved.

Optionally, fig. 4 is a flow chart of another online course contract signing method according to the first embodiment of the present application, as shown in fig. 4, where the method further includes:

Step 401, judging whether the data string is accurately filled into the corresponding custom field;

If at least one data string is not accurately filled into the corresponding custom field, executing the pre-written script program again, and filling the data strings into the custom field consistent with the carried identification until each data string is accurately filled into the corresponding custom field.

In connection with the scenario example, it is checked whether each custom field is empty, if at least one custom field is empty. If the number of at least one custom field is inconsistent with the number of the filled content, judging that at least one data string is not accurately filled in the corresponding custom field. At this time, the filling of each custom field should be canceled, the pre-written script program is re-executed, and whether the data strings are accurately filled into the corresponding custom fields is re-determined until each data string is accurately filled into the corresponding custom fields. Specifically, if no custom field is empty and the number of each custom field is consistent with the number of the filled content, it is determined that each data string is accurately filled into the corresponding custom field, and at this time, execution of the pre-written script program may be stopped. Based on the method provided by the example, each data can be ensured to be correctly filled in the custom field to be corresponding.

Optionally, the user information includes an access subject of the user, fig. 5 is a flowchart of yet another online course contract signing method provided in the first embodiment of the present application, and as shown in fig. 5, the method further includes:

step 501, encrypting the generated contract corresponding to the user to obtain an encrypted contract;

Step 502, adding a corresponding ID to the encrypted contract, and binding the ID with the access subject of the user.

In combination with the scene example, the encryption mode of the contract can adopt symmetric encryption or asymmetric encryption. The characterization form of the access subject can be a login account number and a login password, the exclusive ID of the contract is added to the encrypted contract, the exclusive ID of the contract can be selected as the default code of the contract, and the access subject of the user is bound with the contract number of the user.

Optionally, fig. 6 is a flowchart of yet another online course contract signing method according to the first embodiment of the present application, as shown in fig. 6, where the method further includes:

Step 601, obtaining an access request of a user, wherein the access request comprises an access subject of the user and an accessed second course;

Step 602, verifying whether the user has access to the second course based on the access subject of the user, if the user has access to the second course, providing an access channel for the user to the second course, and if the user does not have access to the second course, rejecting the access request of the user.

In combination with the scenario example, if the user wants to access the second course in the course library, the user may initiate an access request for the second course, specifically, may first log in through the access subject of the user, then select the second course in the course library, and if the user selects to access the second course, then generate an access request for the second course. And verifying whether the user has scope authority to the second course based on the access subject of the user, if the second course is the course purchased by the user, such as the course A of the version 2, judging that the user has the access authority to the second course, and establishing an access channel between the user and the second course so as to enable the user to realize the access to the second course. Otherwise, if the second course is not the course purchased by the user, the user can be judged to not have the access right to the second course, and the access request of the user is refused. The present example can ensure that a user can only access courses with access rights by performing rights determination on the access request of the user.

Optionally, fig. 7 is a flowchart of still another online course contract signing method according to the first embodiment of the present application, as shown in fig. 7, in step 602, verifying whether the user has access rights to the second course based on the access subject of the user includes:

step 701, determining a bound ID through an access main body, and determining a corresponding encryption contract through the bound ID;

Step 702, decrypting the encrypted contract to obtain a digital signature of the user;

Step 703, if the second course is a course with access rights for the user represented by the digital signature, determining that the user has access rights for the second course;

Step 704, if the second course is not a course with access rights for the user represented by the digital signature, determining that the user does not have access rights for the second course.

In combination with the scenario example, according to the binding between the access subject and the ID of the encrypted contract, the access subject of the user can be determined through the access request of the user initiating the access request, then the ID of the encrypted contract bound with the access subject of the user is determined according to the access subject of the user, after the encrypted contract is decrypted through the key used in the same encryption, the related content of the contract can be checked, including the digital signature corresponding to the user, and whether the user has the access right to the second course can be determined based on the digital signature. For example, if the course access right represented by the digital signature includes a second course, for example, the second course is a course a of version 2 purchased by the user, it may be determined that the user has access right to the second course, otherwise, if the course access right represented by the digital signature does not include the second course, it is determined that the user does not have access right to the second course. Based on the method provided by the present example, it can be determined whether the user has access rights to the courses involved in the access request by means of digital signatures.

Optionally, the method further comprises:

and monitoring whether the contract is abnormal or not in real time, and repairing the contract when the contract is abnormal.

In connection with scenario examples, contract status is monitored, including signing, fulfillment, renewal and termination of the contract, and whether the contract is normally fulfilled at various stages is monitored. For example, if the rights of the digital signature of the user are monitored, such as if the user selects a specific service when signing a contract, it is necessary to monitor whether the course scope and the digital signature in the user's contract are updated with the update of the course version. Monitoring the contract in each stage can ensure that when the contract has abnormality in any stage, such as digital signature abnormality, the contract abnormality can be repaired even.

Optionally, fig. 8 is a flowchart of yet another online course contract signing method according to the first embodiment of the present application, where as shown in fig. 8, the method further includes:

Step 801, determining the management authority of each relevant role of each contract to the contract;

step 802, if the contract is updated, notifying each relevant role of the contract.

In combination with the scene example, the related roles of the contract mainly comprise a user, a producer, a manager and the like of the contract, wherein the user only has the viewing authority of the contract, and after the formal generation of the contract, the user does not have the modification authority of the contract. The producer of the contract can update the course range related in the contract and update the digital signature of the user after the version of the course purchased by the user is updated according to the special service signed by the user, so as to generate the updated contract. After the contract is updated, the updated contract can be sent to each corresponding role in a short message or mail mode, so that each role can know the updating condition of the contract, and the updated contract can be managed in time by the manager conveniently.

According to the embodiment, the access authority of the version of the course is limited by generating the digital signature, so that a user can only access the purchased version of the course, the flexibility of accessing the front line to the user can be improved, the user is prevented from accessing the version of the course which is not purchased, and the economic loss is reduced.

Example two

Fig. 9 is a schematic structural diagram of an online course contract signing method device according to a second embodiment of the present application, where, as shown in fig. 9, the device includes:

A determining module 91, configured to determine a contract template, user information and user requirements, where the contract template includes at least one custom field, and the user requirements include a first version of a purchased first course and whether a specific service is allowed, and the specific service characterizes an updated version of the first course that is automatically purchased by the user;

The processing module 92 is configured to determine, based on the user information and the user requirement, content corresponding to each custom field in the contract template, and fill the content corresponding to each custom field into the respective definition field, and generate a contract corresponding to the user and a digital signature, where the digital signature characterizes access rights of the user to each version of the first course.

In connection with the scenario example, the determination module 91 may create a contract template from a template editor in the contract management system, including static fields and dynamic fields in the contract template, where the static fields are contract default content, such as unchangeable fields like contract numbers. The dynamic field is a custom field of the contract, and needs to be determined according to the client information and the client requirement, for example, the course title, the course scope, the price strategy, the payment terms and the like can be custom filled according to the client requirement. User requirements may be determined by customer communication, face-to-face meetings, emails, online questionnaires, or requirement collection tools, recorded by a customer relationship management (Customer Relationship Management, abbreviated CRM) system, and the online forms are used to collect and sort the customer's requirement data, ensuring the integrity and accuracy of the requirements. The course title may be based on the course purchased by the user, and the first course purchased by the user is course a, and the course title may be: "purchase treaty for course A", the specific title may be based on the actual situation; the course scope characterizes the purchased courses in the user requirements, the user requirements comprise specific services, the specific services are optional services, namely, the user can purchase the updated version of the purchased courses automatically, for example, if the first course purchased by the user is the course A, and the first version of the purchased course A is the current latest version-version 2, the course scope is the version 2 of the course A purchased by the user. If the user still wants to view the course content in the subsequent updated version, the user can select a specific service; conversely, if the user only wants to view version 2 of course a, the user may not select a particular service. The field of the price policy may be based on the user's needs, and if the user selects a particular service, the pricing at the price policy should be the sum of the prices of version 2 and the subsequent updated versions, and if the user does not select a particular service, the pricing at the price policy should be the pricing of course a of version 2. After each custom field is filled, the processing module 92 may generate a contract for the course purchased by the user and a digital signature, which may be in the form of a key pair. The digital signature characterizes the access authority of the user to the course, the digital signature can be based on the range of the course purchased by the user, and if the range of the course purchased by the user is the version 2 of the course A, the access authority corresponding to the digital signature of the user is the version 2 of the course A. The access authority of the version of the course is limited by generating the digital signature, so that the user can only access the purchased version of the course, the flexibility of accessing the front line to the user can be improved, the user is prevented from accessing the version of the course which is not purchased, and the economic loss is reduced.

Optionally, for the user selecting the specific service, the user still has the right to access the subsequent version of the course a, but the digital signature generated according to the contract can only access the version 2 purchased at the time, so after the version of the course a is updated, the processing module 92 needs to update the contract of the user receiving the specific service, for example, if the course a has been updated to the version 3, the course range in the contract of the user receiving the specific service can be updated to the version 2 and the version 3 of the course a, and then the digital signature is updated, so that the digital signature has the access right to the version 2 and the version 3 of the course a. Based on the method provided by the example, after the version of the first course purchased by the user is updated, the user can have access to the updated version by updating the available course range and the digital signature.

Alternatively, the processing module 92 may number each dynamic field, i.e., custom field, in the same template, such as the title of the course numbered 1, the scope of the course numbered 2, the price policy numbered 3, the payment terms numbered 4, and so on. After determining the content to be filled in of each custom field, the content to be filled in of each custom field can be added with the same content as the corresponding custom field. Such as curriculum topics: the processing module 92 can determine the serial number of "purchase treaty of course a" as serial number 1, and similarly, if the course range is: "version 2 of course A", the number of "version 2 of course A" may be designated as number 2, in this way, the contents of each custom field are numbered. Since the contents of the custom fields are mostly in text form, in order to automatically fill the contents of each custom field into the corresponding custom field, the processing module 92 may encode the contents of each custom field first, the encoded number is unchanged, and according to a pre-written script program, fill each encoded data string into the same custom field encoded, so as to improve the efficiency of automatic filling.

Optionally, the processing module 92 checks whether each custom field is empty, and if at least one custom field is empty, determines that at least one data string is not accurately populated into the corresponding custom field. If no custom field is empty, it is detected whether the number of each custom field is consistent with the number of the filled content, and if at least one custom field is inconsistent with the number of the filled content, the processing module 92 determines that at least one data string is not accurately filled into the corresponding custom field. At this time, the filling of each custom field should be canceled, the pre-written script program is re-executed, and whether the data strings are accurately filled into the corresponding custom fields is re-determined until each data string is accurately filled into the corresponding custom fields. Specifically, if no custom field is empty and the number of each custom field is consistent with the number of the filled content, the processing module 92 determines that each data string is accurately filled into the corresponding custom field, and at this time, execution of the pre-written script program may be stopped. Based on the method provided by the example, each data can be ensured to be correctly filled in the custom field to be corresponding.

Alternatively, the encryption mode of the contract can be symmetric encryption or asymmetric encryption. The characterization form of the access subject can be a login account number and a login password, the exclusive ID of the contract is added to the encrypted contract, the exclusive ID of the contract can be selected as the default code of the contract, and the access subject of the user is bound with the contract number of the user.

Optionally, if the user wants to access a second course in the course library, the processing module 92 may initiate an access request for the second course, specifically, may first log in through the access subject of the processing module, then select from the course library, and if the user selects to access the second course, may generate an access request for the second course. And verifying whether the user has scope authority to the second course based on the access subject of the user, if the second course is the course purchased by the user, such as the course A of the version 2, judging that the user has the access authority to the second course, and establishing an access channel between the user and the second course so as to enable the user to realize the access to the second course. Otherwise, if the second course is not the course purchased by the user, the user can be judged to not have the access right to the second course, and the access request of the user is refused. The present example can ensure that a user can only access courses with access rights by performing rights determination on the access request of the user.

The processing module 92 may determine, according to the binding between the access subject and the ID of the encrypted contract, the access subject of the user according to the access request of the user who initiates the access request, determine, according to the access subject of the user, the ID of the encrypted contract bound thereto, decrypt the encrypted contract by using the key used in the same encryption, and then view the related content of the contract, including the digital signature corresponding to the user, and determine whether the user has access rights to the second course based on the digital signature. For example, if the course access right represented by the digital signature includes a second course, for example, the second course is a course a of version 2 purchased by the user, it may be determined that the user has access right to the second course, otherwise, if the course access right represented by the digital signature does not include the second course, it is determined that the user does not have access right to the second course. Based on the method provided by the present example, it can be determined whether the user has access rights to the courses involved in the access request by means of digital signatures.

Optionally, the processing module 92 monitors the contract status, including signing, fulfilling, renewing and terminating the contract, monitors whether the contract is normally fulfilled at each stage, and monitors each stage of the contract, so as to ensure that when the contract has an abnormality at any stage, the abnormality of the contract can be repaired.

Optionally, the relevant roles of the contract mainly include a user, a producer and a manager of the contract, wherein the user only has the viewing authority of the contract, and after the formal generation of the contract, the user does not have the modification authority of the contract. The producer of the contract may update the course ranges involved in the contract and update the digital signature of the user after the update of the version of the course purchased by the user occurs according to the special service signed by the user, thereby generating an updated contract. After the contract is updated, the processing module 92 can send the updated contract to each corresponding role in a short message or mail mode, so that each relevant role can know the updating condition of the contract, and the updated contract can be managed in time by the manager conveniently.

According to the embodiment, the access authority of the version of the course is limited by generating the digital signature, so that a user can only access the purchased version of the course, the flexibility of accessing the front line to the user can be improved, the user is prevented from accessing the version of the course which is not purchased, and the economic loss is reduced.
