The invention relates to the technical field of Internet ordering, in particular to a method, a device and a system for preventing malicious ordering.

[ background of the invention ]

The code scanning ordering technology is more and more widely applied, when a customer orders in a restaurant, a user terminal scans a two-dimensional code pasted on a meal position, an interface of an ordering program is entered, an electronic menu can be checked on the interface, meal items can be selected, orders can be placed and paid, restaurant workers can automatically receive orders and prepare meals and give meals for the meal position, the ordering efficiency of the customer is effectively improved in the whole process, and the time of the restaurant workers is effectively saved.

However, the inventor of the present invention finds that, because the two-dimensional code attached to the dining position is fixed for a long time, if a malicious person takes a picture of the two-dimensional code and saves the two-dimensional code, or decodes the two-dimensional code to obtain decoded information, even if a meal is not ordered in a restaurant in the future, the two-dimensional code can still be scanned or enter an ordering interface according to the decoded information, and relevant malicious operations are performed, which specifically includes:

on the first hand, malicious personnel can obtain the current order information (including ordered food and the like) of the target meal position on the ordering interface, so that the privacy information of the ordering preference and the like of the ordering customer of the target meal position can be obtained.

In the second aspect, malicious persons can take a large number of pictures and store two-dimensional codes of different meal positions in the restaurant, so that ordering information of customers in the restaurant can be continuously and massively acquired, and operation information of the restaurant can be acquired.

In a third aspect, malicious personnel can also maliciously place orders on the ordering interface and the like, which brings unnecessary interference to restaurant workers and customers ordering at the target meal positions.

In the prior art, patent application document 'a method for scanning and ordering food by an intelligent device' (patent application number: 201711231307.2) and patent application document 'a method, a system, a terminal, a server and a medium for preventing malicious ordering' (patent application number: 201910042570.X) all provide a technology for preventing malicious ordering, but the inventor finds that the two patent application documents mainly identify malicious ordering behaviors by comparing coordinate positions of a user terminal and a restaurant, because the coordinate position in the user terminal is easy to forge and a malicious person can perform related malicious operations near the restaurant, the methods provided by the two patent application documents can not effectively prevent the malicious ordering behaviors, and because the coordinate position for acquiring the user terminal may have errors and the user terminal is difficult to acquire positioning signals indoors, and the like, and also greatly limits the popularization and application of the technology.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiment of method for preventing malicious meal ordering

Referring to fig. 1, a flowchart of an embodiment of a method for preventing malicious food ordering according to the present invention is shown. The embodiment is exemplified by applying the method to the ordering server, and the method may include:

and step 101, receiving an access request aiming at a target dining position sent by a user terminal.

The ordering user accesses the ordering server through the user terminal, and an access request aiming at a target meal position is sent to the ordering server; accordingly, the ordering service end receives the access request.

The ordering user typically refers to a customer who has a meal in a restaurant. The user terminal refers to mobile intelligent terminal equipment such as a smart phone, a tablet computer and a smart watch. The dining position refers to a position for providing dining service for a user ordering food in a dining room, and comprises a seat, a dining table or a bundlery and the like. The target meal position refers to a meal position to be used by the ordering user, for example, after the ordering user sits at the target meal position, the ordering user starts ordering with the user terminal, and after ordering and placing an order, the restaurant staff provides meal preparation and delivery service for the target meal position.

Specifically, the sending of the access request for the target meal location from the user terminal to the ordering server may be triggered by the ordering user inputting relevant information on a user interface of the user terminal, or triggered by the user terminal according to decoding information of the graphic code. The graphic code may be a two-dimensional code or a bar code, or may be other graphics whose information can be obtained by scanning and decoding, for example, taking a user terminal running a wechat ordering applet as an example, the graphic code may be a wechat applet code.

Specifically, for example, the user terminal triggers sending of an access request to the ordering server according to decoding information of the graphic code, the graphic code is pasted on the dining positions of the restaurant, the graphic code corresponds to each dining position in the restaurant one by one, the ordering user scans the graphic code pasted on the seated dining positions by using the user terminal, the user terminal decodes the graphic code, and the access request is sent to the ordering server according to the decoding information of the graphic code. Specifically, according to the type of the application service provided by the ordering service end, the sending the access request to the ordering service end according to the decoding information of the graphic code may further include:

taking the mobile application service provided by the ordering service terminal as an example, the mobile application client of the ordering service terminal is operated on the user terminal, and the ordering user scans the graphic code through the code scanning function carried by the mobile application client and sends an access request to the ordering service terminal according to the decoding information of the graphic code.

Taking the example that the ordering service terminal provides the website application service, the ordering user uses a code scanning function carried by a browser on the user terminal, or the ordering user uses a WeChat code scanning tool or other graphic code scanning tools to scan the graphic code, triggers the browser to access the ordering service terminal according to decoding information of the graphic code, and sends the access request to the ordering service terminal.

Taking the small program application service provided by the ordering service terminal as an example (such as the application service of a WeChat small program or a Payment small program), the ordering user scans the graphic code through a code scanning tool of a small program host environment (such as a WeChat client or a Payment small program) on the user terminal, the small program host environment loads and runs the ordering small program according to decoding information of the graphic code, and the ordering small program sends the access request to the ordering service terminal according to parameter information transmitted in the decoding information.

And 102, acquiring the meal position identification information of the target meal position according to the access request.

The meal location identification information is information for identifying a specific location of the target meal location in the target restaurant, for example, for identifying that the target meal location is a number-th seat or table in the target restaurant, or for identifying that the target meal location is a number-th booth in the target restaurant, or the like. If the ordering service end is mainly used for providing ordering service for a single restaurant, the meal position identification information can mainly consist of meal position identification; if the ordering service end is used for providing ordering service for a plurality of restaurants, the meal position identification information can mainly comprise restaurant identifications and meal position identifications. The restaurant identifier is used for identifying different restaurants; the meal location identifier is an identifier for identifying a specific meal location in a restaurant, such as a serial number of a seat, a table or a booth.

Specifically, the meal ordering server obtains the meal position identification information of the target meal position according to the access request, and may include various embodiments, for example:

in one embodiment, the access request includes the meal location identification information, and the ordering server obtains the meal location identification information from the access request.

In one embodiment, an association relationship between the associated information and the meal location identification information is established in advance, and if the access request contains the associated information associated with the meal location identification information, the meal location identification information is obtained in the association relationship according to the associated information. For example, an association relationship between a unique character string and meal position identification information of the target meal position is established in advance, that is, the association information is the unique character string, and when an access request including the unique character string is received, the meal position identification information is obtained in the association relationship according to the unique character string.

It can be understood that, as described in step 101, if the access request is triggered by the user terminal based on the decoding information of the graphical code, the meal location identification information is already carried in the graphical code, or the associated information associated with the meal location identification information is already carried in the graphical code, so that the access request sent by the user terminal according to the decoding information of the graphical code can include the meal location identification information or the associated information.

It is understood that, as described in step 101, the graphic code corresponds to each meal position in the restaurant one by one, that is, the meal position identification information or the associated information carried in the graphic code corresponds to each meal position in the restaurant one by one, so that the meal position identification information obtained according to the access request is the meal position identification information corresponding to the target meal position.

And 103, acquiring the user identification information of the user who logs in the user terminal.

In the process that the user terminal accesses the ordering server, the user terminal logs in the ordering server by a user; correspondingly, the ordering service side carries out identity authentication or authorization verification on the login user, and if the identity authentication or authorization verification passes, the ordering service side obtains the user identification information of the login user. The user identification information refers to information for uniquely identifying a login user, and includes a user identifier or an account, a mobile terminal number, and the like.

The method for acquiring the user identification information of the user terminal login user specifically includes various implementation modes:

in the first implementation manner, a user identifier or an account of a user who logs in a user terminal is obtained, and the user identifier or the account is used as the user identification information.

The ordering service terminal obtains a user identification or an account number of a user terminal login user, and the user identification or the account number is used as the user identification information.

For example, a meal ordering user inputs a user account and a password at a user terminal to log in a meal ordering service terminal, the meal ordering service terminal performs identity authentication on the user account and the password, and after the authentication is passed, the meal ordering service terminal takes the user account as the user identification information.

For another example, taking the ordering server providing the website application service and accessing the trusted user to authorize login as an example, the ordering server obtains the authorized login of the trusted login user, obtains an interface call credential (access _ token) of the trusted login user, and then performs trusted open platform authorization relationship interface call through the access _ token, including obtaining the OpenID or the UnionID of the trusted login user, and the ordering server uses the OpenID or the UnionID as the user identification information. It is understood that OpenID is an identifier of a wechat login user in a mobile application, a website application, or a public account (including an applet) that respectively and uniquely corresponds to the identity of the wechat login user, and UnionID is an identifier of a mobile application, a website application, and a public account (including an applet) that correspond to the identity of the same wechat login user under the same wechat open platform account.

For another example, taking the ordering service end providing the WeChat applet application service as an example, the wx.login () interface may be called to obtain the temporary login credential code of the WeChat login user, then the auth.code2Session interface is called to replace the OpenID or UnionID of the WeChat login user, and the ordering service end uses the OpenID or UnionID as the user identification information.

For another example, taking the ordering service end providing the payment applet application service as an example, after login is authorized by the payment applet user, the user _ id parameter value is obtained by calling the Alipay system oauth token interface, where the user _ id is a unique identifier of the payment applet user, and the user _ id parameter value is used as the user identification information.

It can be understood that the user may also log in the ordering service end in other identity authentication manners (e.g., biometric authentication), and accordingly, the ordering service end performs corresponding identity authentication on the login user and obtains a user identifier or an account of the login user.

It is to be understood that information for uniquely identifying the login user may be used as the user identification information, for example, if the ordering server identifies the login user with a unique identifier, and the user account or/and mobile terminal number or/and micro credit user OpenID or/and micro credit user UnionID or/and user _ id of the payer and the like of the login user is bound with the unique identifier, the unique identifier may be obtained according to the association relationship, and the unique identifier may be used as the user identification information.

It can be understood that if the user terminal login user passes the identity authentication of the ordering service terminal and the user terminal maintain a session state, the ordering service terminal can also obtain the user identifier or the account of the login user according to the session state.

In the second embodiment, the mobile terminal number of the user who logs in the user terminal is obtained, and the mobile terminal number is used as the user identification information.

And the ordering server acquires the mobile terminal number of the user logged in by the user terminal, and the mobile terminal number is used as the user identification information. The mobile terminal number is the number that needs to be dialed to call a mobile subscriber, also called MSISDN (mobile subscriber ISDN number), also commonly referred to as the mobile phone number.

In the ordering service terminal, if the mobile terminal number is used as the user account of the user, or the user identifier or the account is bound with the mobile terminal number, the mobile terminal number of the login user can be obtained.

For example, in the ordering service side, the mobile terminal number is used as the account of the login user, and after the user terminal successfully logs in through the mobile terminal number and the password (or the short message authentication code), the ordering service side uses the mobile terminal number as the user identification information.

For another example, taking the ordering service end providing the wechat applet application service as an example, the number of the mobile terminal bound by the wechat login user may be obtained based on the wechat interface service. Specifically, the value of the button component open-type is set as getPhoneNumber, when the ordering user clicks and agrees, encrypted data returned by the WeChat interface service is acquired through a bindgetPhoneNumber event callback, and then the ordering service end is decrypted by combining the session _ key and the app _ id to acquire the mobile terminal number.

For another example, taking the ordering service end providing the application service of the small payment treasures program as an example, when the authorization of the login user of the payment treasures is obtained, a token used for exchanging the user information is obtained, and the number of the mobile terminal is obtained by calling the interface for obtaining the member mobile phone number. Specifically, the value of the < button > component open-type is set as getAuuthorize, after the ordering user clicks and agrees, the encrypted data returned by the Payment treasure server is obtained through a my.

104, judging whether the login user is the current meal ordering user of the target meal position according to the meal position identification information and the user identification information; if the logged-in user is judged to be the current meal ordering user of the target meal position, the following step 105 is executed.

The ordering server judges whether the login user is the current ordering user of the target meal position according to the meal position identification information and the user identification information; if the logged-in user is judged to be the current meal ordering user of the target meal position, the following step 105 is executed.

The current ordering user refers to the ordering user who is using the target meal position. The method for identifying the target meal position by the meal position identification information and the login user by the user identification information includes multiple implementation modes, and specifically includes the following steps:

in the first implementation mode, corresponding current ordering user identification information is obtained according to the meal position identification information, and whether the current ordering user identification information is consistent with the user identification information or not is compared; if the current meal ordering user is consistent with the target meal position, judging that the login user is the current meal ordering user of the target meal position; if not, judging that the login user is not the current meal ordering user of the target meal position.

For example, the meal ordering server generates current meal position data, and the current meal position data is used for indicating that the corresponding meal position is currently used by the corresponding user; specifically, the current meal position data includes a corresponding relationship between meal position identification information and current meal ordering user identification information, wherein the meal position identification information is used for indicating a meal position, and the current meal ordering user identification information is used for indicating a meal ordering user who is using the meal position at present. The ordering server acquires corresponding current ordering user identification information in the current meal position data according to the meal position identification information, and compares whether the current ordering user identification information is consistent with the user identification information or not; if the current meal ordering user is consistent with the target meal position, judging that the login user is the current meal ordering user of the target meal position; if not, judging that the login user is not the current meal ordering user of the target meal position. It can be understood that if the meal position identification information corresponds to a plurality of current meal ordering user identification information, in an actual application scenario, it can be understood that one meal position is being used by a plurality of meal ordering users, and each current meal ordering user identification information in the plurality of current meal ordering user identification information is respectively compared with the user identification information to determine whether the current meal ordering user identification information is consistent with the user identification information; if the current meal ordering user is consistent with the target meal position, judging that the login user is the current meal ordering user of the target meal position; otherwise, judging that the login user is not the current meal ordering user of the target meal position.

For another example, taking the meal order identification information mainly consisting of the restaurant identifier and the meal order identifier as an example, the ordering server generates current meal order data for different restaurant identifiers, that is, creates current meal order data by using the restaurant identifiers respectively, and the current meal order data includes the corresponding relationship between the meal order identifier and the current ordering user identification information. The ordering server side obtains the restaurant identifier and the meal position identifier in the meal position identification information, obtains the current ordering user identification information corresponding to the meal position identifier from the current meal position data of the restaurant identifier according to the meal position identifier, and then judges whether the login user is the current ordering user of the target meal position or not by comparing whether the current ordering user identification information is consistent with the user identification information or not, wherein the specific comparison mode is the same as or similar to the comparison mode, and is not repeated herein.

It can be understood that the corresponding current ordering user identification information is obtained according to the meal position identification information, not only the corresponding current ordering user identification information is directly obtained according to the meal position identification information, but also the corresponding current ordering user identification information is indirectly obtained, for example, the corresponding relationship between the meal position identification information and the current order is set in the current meal position data, and the corresponding relationship is set between the current order and the current ordering user identification information, so that when the corresponding current order is obtained according to the meal position identification information, the corresponding current ordering user identification information can be obtained according to the corresponding current order.

In the second implementation mode, corresponding current meal position identification information is obtained according to the user identification information, and whether the current meal position identification information is consistent with the meal position identification information or not is compared; if the current meal ordering user is consistent with the target meal position, judging that the login user is the current meal ordering user of the target meal position; if not, judging that the login user is not the current meal ordering user of the target meal position.

For example, corresponding current meal position identification information is set for user identification information in the ordering server, the corresponding current meal position identification information is obtained according to the user identification information, and whether the current meal position identification information is consistent with the meal position identification information or not is compared; if the current meal ordering user is consistent with the target meal position, judging that the login user is the current meal ordering user of the target meal position; if not, judging that the login user is not the current meal ordering user of the target meal position. It can be understood that if the user identification information corresponds to a plurality of current meal position identification information, in an actual application scenario, it can be understood that one meal ordering user is using a plurality of meal positions, and each current meal position identification information in the plurality of current meal position identification information is respectively compared with the meal position identification information to determine whether the current meal position identification information is consistent with the meal position identification information; if the current meal ordering user is consistent with the target meal position, judging that the login user is the current meal ordering user of the target meal position; otherwise, judging that the login user is not the current meal ordering user of the target meal position.

For another example, in an example that the meal location identification information mainly includes a restaurant identifier and a meal location identifier, the ordering server generates current meal location data for different restaurant identifiers, that is, different current meal location data are respectively created by the restaurant identifiers, and the current meal location data includes user identification information and a corresponding current meal location identifier, where the user identification information is used to indicate an ordering user, and the current meal location identifier is used to indicate a specific meal location in a target restaurant that is being used by the ordering user. The ordering server side obtains a restaurant identifier and a meal position identifier in the meal position identification information, obtains a current meal position identifier corresponding to the user identification information from current meal position data of the restaurant identifier according to the user identification information, then compares whether the current meal position identifier is consistent with the meal position identifier in the meal position identification information, and if so, judges that the logged-in user is the current ordering user of the target meal position; if not, judging that the login user is not the current meal ordering user of the target meal position.

It can be understood that, the corresponding current meal location identification information is obtained according to the user identification information, not only the corresponding current meal location identification information is directly obtained according to the user identification information, but also the corresponding current meal location identification information is indirectly obtained, for example, a corresponding relationship between the user identification information and the current order is set, and the corresponding relationship is set between the current order and the current meal location identification information, so that when the corresponding current order is obtained according to the user identification information, the corresponding current meal location identification information can be obtained according to the corresponding current order.

In a third implementation manner, corresponding current ordering information or/and current order information is obtained according to the meal position identification information and the user identification information, and if the corresponding current ordering information or/and current order information is obtained, it is determined that the logged-in user is the current ordering user of the target meal position.

In the process that a user terminal logs in a target meal position used by a user, a meal ordering service terminal generates corresponding current meal ordering information or/and current order information according to the indication of the user terminal, namely the meal ordering service terminal creates the corresponding current meal ordering information or/and current order information for the meal position identification information and the user identification information in use.

The current ordering information refers to ordering information which corresponds to the target meal position and has not been ordered yet, service processing such as food preparation and delivery and the like is not required to be provided by restaurant workers, and the ordering information comprises information such as the number of people having meals, meals (the meals comprise dishes, drinks and/or staple food and the like); the current order information refers to order information which needs restaurant workers to provide service processing such as catering and meal delivery at present. It should be noted that the current order information may be paid or unpaid, and the embodiment of the present invention is not limited to this.

Therefore, if the corresponding current meal ordering information or/and the current order information is obtained according to the meal position identification information and the user identification information, it is indicated that the corresponding current meal ordering information or/and the current order information is generated by the logged-in user in the process of using the target meal position, and it can be determined that the logged-in user is the current meal ordering user of the target meal position.

Optionally, before step 104 is executed, corresponding steps can also be executed according to the usage status of the target dining position. The specific implementation mode comprises the steps of obtaining the use state of the target meal position according to the meal position identification information; if the target dining position is in the use state, executing the step 103 and the subsequent steps; further, if the target dining position is not in use, step 104 and jump execution step 105 are not executed, and step 103 may determine whether to execute according to whether user identification information of the logged-in user needs to be acquired when step 105 is executed. The method has the functions that for the target meal position in the use state, step 104 needs to be executed to judge whether the login user is the current meal ordering user of the target meal position, and step 105 is determined to be executed according to the judgment result, so that other login users can be prevented from using the target meal position; for a target meal location that is not in use, execution 105 may jump to use the target meal location and perform ordering related operations. The obtaining of the use state of the target meal position according to the meal position identification information may further include various embodiments, for example, obtaining a state identifier corresponding to the meal position identification information according to the meal position identification information, where the state identifier is used to indicate whether the target meal position is in the use state, and if the state identifier indicates that the target meal position is in the use state, determining that the target meal position is in the use state, otherwise, determining that the target meal position is not in the use state; for another example, when a target meal position is used, corresponding current meal ordering information or/and current order information is generated for the target meal position, or corresponding current meal ordering user identification information is set for the target meal position, so that current meal ordering information or/and current order information or/and current meal ordering user identification information corresponding to the meal position identification information can be obtained according to the meal position identification information, if the current meal ordering information or/and current order information or/and current meal ordering user identification information corresponding to the meal position identification information is obtained, the target meal position is determined to be in a use state, otherwise, the target meal position is determined not to be in the use state. It can be understood that, when the usage status of the target meal location is determined according to the current meal ordering user identification information corresponding to the acquired meal location identification information, when the first implementation manner of step 104 is implemented, the current meal ordering user identification information corresponding to the acquired meal location identification information may not be acquired repeatedly, and the current meal ordering user identification information acquired when the usage status of the target meal location is acquired may be compared with the user identification information to determine whether the current meal ordering user identification information is consistent.

Further optionally, when the target meal location is not in a use state and the step 105 is skipped to perform, the logged-in user may be set as the current meal ordering user of the target meal location according to the meal location identification information and the user identification information, so that when the logged-in user visits the meal ordering service end again, the meal ordering service end may determine that the logged-in user is the current meal ordering user of the target meal location. The current meal ordering user setting the login user as the target meal position according to the meal position identification information and the user identification information may include various embodiments, for example, corresponding to the first embodiment in step 104, the current meal ordering user identification information corresponding to the meal position identification information is set as the user identification information; for another example, corresponding to the second embodiment in step 104, the current meal position identification information corresponding to the user identification information is set as the meal position identification information; therefore, when the user terminal accesses the ordering server again, the ordering server can judge whether the login user of the user terminal is the current ordering user of the target meal position or not by using the corresponding implementation mode. Further, when the usage status of the target meal position is determined according to the status identifier corresponding to the meal position identification information, the status identifier corresponding to the meal position identification information may be further set to indicate that the target meal position is in the usage status, so that when the user terminal scans the graphic code of the target meal position again to access the ordering service terminal, the ordering service terminal may determine that the target meal position is in the usage status.

Further optionally, when the target meal location is not used, a situation that the target meal location is used maliciously may exist, for example, even if a malicious person does not order in the target restaurant, the malicious person may still perform an ordering related operation by scanning a pre-saved graphic code; further, if the ordering server sets the login user as the current ordering user of the target meal position according to the meal position identification information and the user identification information, malicious personnel can be set as the current ordering user of the target meal position, so that the normal ordering user can not use the target meal position. Therefore, in order to prevent the situation that the pre-saved graphic code maliciously occupies the meal position when a person not in the restaurant scans the pre-saved graphic code, when the target meal position is not in the use state and the execution step 105 is skipped, the execution step 105 may be executed after the confirmation or the security verification by the merchant terminal, and specifically may include:

in the first embodiment, step 105 is performed after the confirmation by the merchant terminal.

The specific process of confirming by the merchant terminal may include:

and the ordering server generates prompt information corresponding to the target meal position, wherein the prompt information is used for indicating whether the merchant terminal agrees to the user terminal to execute ordering related operation on the target meal position. The prompt information comprises user information of the login user, for example, corresponding user information is set for the user in the ordering server, the corresponding user information is obtained according to the user identification information, and the corresponding user information is the user information of the login user; for another example, if the login user is a WeChat login user or a Payment treasure login user, the interface service provided by the WeChat or Payment treasure open platform is called, and the user information of the login user is obtained after the user authorization is obtained; the user information comprises all or part of information in the user name (such as name and nickname), or/and the user head portrait, or/and all or part of information of the mobile terminal number, and the like. The prompt information may further include meal position information of the target meal position (for example, a number of dining table or a bunk, or a number of dining table or a bunk of a certain dining room, etc.), and the corresponding meal position information may be obtained according to the meal position identification information, where the corresponding meal position information is the meal position information of the target meal position.

And outputting the prompt information to the merchant terminal. For example, the prompt information is displayed on a management interface of the merchant terminal; for another example, the prompt message is sent to the merchant terminal; in addition, buttons indicating approval and rejection may be displayed to ask the restaurant staff whether to approve;

the restaurant staff checks the prompt information and feeds back information indicating approval or rejection to the ordering server through the merchant terminal; for example, if the restaurant staff agrees, click a button indicating agreement; if the restaurant staff member rejects, clicking a button representing the rejection;

and the ordering server receives the information fed back by the merchant terminal, and if the information which is fed back by the merchant terminal and indicates agreement is received, the ordering server is confirmed by the merchant terminal.

In the second embodiment, the security authentication is performed on the ue, and if the ue passes the security authentication, step 105 is executed.

The security verification of the user terminal may include:

generating safety verification information corresponding to the meal position identification information, for example, randomly generating a character string, and setting the character string as the safety verification information corresponding to the meal position identification information, wherein the randomly generated character string is preferably a pure number of four to six digits;

informing the safety verification information to a food ordering user, for example, when the food ordering user orders food, a restaurant worker acquires the safety verification information corresponding to the target meal location through a merchant terminal, and informs the safety verification information to the food ordering user;

displaying a user interface for safety verification on a user terminal, inputting safety verification information serving as safety verification information into the user interface by a meal ordering user, and triggering a safety verification process;

the user terminal sends the input safety verification information to the ordering server, and the ordering server receives the safety verification information;

the ordering server acquires safety verification information corresponding to the meal position identification information according to the meal position identification information, and compares whether the safety verification information is consistent with the safety verification information or not; if the user terminal is consistent with the security authentication request, determining that the user terminal passes the security authentication; otherwise, the user terminal is determined not to pass the security authentication.

It should be further noted that, when the ordering service end determines whether the logged-in user is the current ordering user of the target meal size according to the meal size identification information and the user identification information, if it is determined that the logged-in user is not the current ordering user of the target meal size, the ordering service end may refuse the logged-in user to perform meal ordering related operations on the target meal size, that is, the following step 105 is not performed; the following step 105 may also be executed after the merchant terminal confirms or passes the security verification, and the current meal ordering user identification information corresponding to the meal location identification information may be further set to include the user identification information, or the current meal location identification information corresponding to the user identification information may be set to include the meal location identification information, and the like, which is not described in detail herein.

And 105, performing ordering related operation on the target meal position according to the indication of the user terminal.

And executing the food ordering related operation on the target food position according to the indication of the user terminal, namely allowing the user terminal to execute the food ordering related operation on the target food position. Specifically, the ordering service end can display a user interface of the ordering related operation to the user terminal, an ordering user performs the ordering related operation on the user interface, and the user terminal sends an ordering related operation instruction to the ordering service end according to the ordering related operation; accordingly, the ordering service end receives the indication and executes ordering related operation on the target meal position according to the indication, wherein the target meal position is identified by the meal position identification information. It can be understood that, according to the session state maintained between the ordering service terminal and the user terminal, the ordering service terminal may receive and execute the ordering related operation instruction sent by the user terminal to the target meal location for multiple times.

The meal ordering related operation comprises the steps of generating current meal ordering information, browsing the current meal ordering information, modifying the current meal ordering information, ordering and the like.

For example, taking the generation of the current ordering information as an example, the ordering user inputs or selects corresponding ordering information on the user interface, such as the number of people who have a meal, the selection of meal (meal includes meal, drinks, staple food, and the like), and sends the corresponding ordering information to the ordering server and instructs to generate the current ordering information, the ordering server generates the current ordering information corresponding to the target meal location, that is, the corresponding ordering information is stored as the current ordering information corresponding to the meal location identification information, so that the corresponding ordering information can be obtained according to the meal location identification information; further, the corresponding ordering information may be stored as the meal location identification information and the current ordering information corresponding to the user identification information, so that when the logged-in user accesses the ordering server again, and when the third implementation manner in step 104 is implemented, the corresponding current ordering information may be obtained according to the meal location identification information and the user identification information, and thus, it may be determined that the logged-in user is the current ordering user of the target meal location.

For another example, taking browsing current meal ordering information as an example, when a meal ordering user triggers an instruction of browsing current meal ordering information on a user interface, the meal ordering service end obtains the current meal ordering information corresponding to the meal position identification information, and returns the corresponding current meal ordering information to the user terminal, and the user terminal receives the corresponding current meal ordering information and displays the corresponding current meal ordering information on the user interface so that the meal ordering user can browse the current meal ordering information. It can be understood that, if the third implementation manner of step 104 is implemented, and the corresponding current meal ordering information has already been acquired according to the meal location identification information and the user identification information, when the current meal ordering information is browsed in this step, the corresponding current meal ordering information may not be acquired again, and the corresponding current meal ordering information acquired in the third implementation manner of step 104 may be returned to the user terminal; of course, the corresponding current food ordering information may also be obtained again to obtain the updated current food ordering information and return the updated current food ordering information to the user terminal.

For another example, taking modifying the current ordering information as an example, when the ordering user browses the current ordering information on the user interface, the current ordering information may also be modified, and when the ordering server receives the modified current ordering information sent by the user terminal, the current ordering information corresponding to the meal position identification information is stored as the modified current ordering information.

For example, the ordering user triggers an ordering operation on a user interface, and the ordering server generates current order information, where the current order information includes the meal location identification information and corresponding ordering information, where the corresponding ordering information may be the current ordering information corresponding to the meal location identification information, and sent to the ordering server after the ordering user inputs or selects the corresponding ordering information on the user interface, or the current ordering information corresponding to the meal location identification information that is stored in advance; because the target meal position is identified by the meal position identification information, the restaurant staff can provide the meal preparation and delivery service related to the corresponding ordering information for the target meal position according to the current order information. Furthermore, the current order information can also comprise the meal position identification information and the user identification information, so that a corresponding login user can be obtained according to the current order information, and a meal ordering user can be identified when restaurant workers provide meal preparation and delivery services; and when the logged-in user accesses the ordering server again, and when the third implementation manner in step 104 is implemented, the ordering server may obtain corresponding current order information according to the meal location identification information and the user identification information, so as to determine that the logged-in user is the current ordering user of the target meal location.

In addition, it should be noted that, in order to improve the utilization rate of the meal positions and avoid that the ordering user occupies the target meal position for a long time, once the target meal position is used, the occupation of the target meal position should be timely removed, for example, the removal of the occupation of the target meal position may be triggered after the login user completes payment for the current order information, or the occupation of the target meal position may be removed by setting the restaurant staff on the management interface of the merchant terminal. Specifically, the elimination of the target meal position occupation can be realized by clearing the current meal ordering information or/and the current order information or/and the current meal ordering user identification information corresponding to the meal position identification information by the meal ordering server; or setting the state identifier corresponding to the meal position identification information to indicate that the target meal position is not in a use state; or, the current meal position data of the meal position identification information and the user identification information are converted into historical meal position data and the like.

In summary, compared with the prior art, the method provided by the embodiment has the following main technical effects: on the first hand, when the target meal position is used by the meal ordering user, only the meal ordering user can use the target meal position, and other meal ordering users cannot use the target meal position, so that malicious meal ordering behaviors such as malicious ordering of the target meal position by malicious personnel, acquisition of current meal ordering information or current meal ordering orders and the like are effectively prevented; in the second aspect, malicious food ordering behaviors do not need to be identified according to the coordinate positions of the user terminal and the restaurant, so that the defects brought to identification of the malicious food ordering behaviors in the aspects of coordinate position errors, indoor difficulty in obtaining and the like are effectively avoided; in addition, if the ordering user needs to use the target meal position which is not in the use state, the meal position can be used only after the confirmation of restaurant staff or the safety verification is passed, and the condition that the meal position is maliciously occupied by the staff who is not in the restaurant in the modes of scanning pre-saved graphic codes and the like is effectively prevented.
