Detailed Description

In order to make the technical solutions in one or more embodiments of the present disclosure better understood, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of one or more embodiments of the present disclosure, but not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments in one or more of the specification without inventive faculty are intended to fall within the scope of one or more of the specification.

One or more embodiments of the present disclosure provide a code scanning control method, apparatus, and system, where a graphic code displayed on a device terminal is dynamically changed, so that a dynamic password uploaded by a client has a certain timeliness, and thus, whether the client is attacked or not can be identified by means of the timeliness of the dynamic password, and effective control is performed in time for identifying a case where the client is illegally attacked by a malicious user, thereby avoiding unnecessary loss to a normal user.

Fig. 1 is a schematic view of an application scenario of a code scanning control system according to one or more embodiments of the present disclosure, as shown in fig. 1, the control system includes: background server, customer end and equipment terminal, wherein, this customer end can be mobile terminal such as smart mobile phone, panel computer, and this background server can be the background server that is used for carrying out supervisory control and has saas service to equipment terminal, and this equipment terminal can be to sweep a yard selling equipment, sweep a yard lease product etc. and wherein, sweep the concrete process of yard control and do:

firstly, a client sends a device control request to a background server, wherein the device control request carries a target dynamic password;

specifically, the client may be an equipment control request sent based on actively scanning a code on an equipment terminal, that is, belonging to a normal active request control equipment terminal; the client can also be a device control request sent by a malicious user through illegal means, namely passively requesting to control the device terminal after being attacked;

then, after receiving the device control request, the background server judges whether a target dynamic password carried in the device control request meets a preset timeliness condition;

specifically, for the condition of an equipment control request sent by a client based on code scanning operation on a graphic code on an equipment terminal, a target dynamic password carried in the equipment control request is valid; because the dynamic password corresponding to the graphic code displayed on the equipment terminal is dynamically updated, a malicious user needs a certain time from the acquisition of the dynamic password to the triggering of a normal user to send an equipment control request carrying the dynamic password to the background server, and therefore, the target dynamic password carried in the equipment control request is invalid under the condition that the malicious user sends the equipment control request by an illegal means;

finally, the background server executes corresponding control operation according to the timeliness judgment result aiming at the target dynamic password;

specifically, when the target dynamic password is determined to be valid, the client belongs to a control device terminal which is normally actively requested from the background server, and at the moment, the background server needs to normally respond to the device control request to control the device terminal to execute a corresponding control action; when the target dynamic password is determined to be invalid, the client belongs to the attacked state and requests the background server to control the equipment terminal, and at the moment, the background server needs to return prompt information to the client, so that the illegal attack behavior of the malicious user is effectively controlled, and unnecessary loss of normal users is avoided.

Fig. 2 is a first flowchart of a code scanning control method provided in one or more embodiments of the present disclosure, where the method in fig. 2 can be executed by the background server in fig. 1, as shown in fig. 2, and the method at least includes the following steps:

s201, receiving an equipment control request sent by a client, wherein the equipment control request carries a target dynamic password;

specifically, the device control request received by the background server may be sent by the client based on an active code scanning operation on a graphic code on the device terminal, that is, the device control request belongs to a normal active request control device terminal of the client; the client can also be sent out under the triggering of a malicious user through an illegal means, namely the client passively requests a control equipment terminal after being attacked;

s202, judging whether a target dynamic password carried in the equipment control request meets a preset timeliness condition, wherein the target dynamic password is in one-to-one correspondence with a dynamically updated graphic code displayed on a target equipment terminal, namely, in a scanning graphic code verification stage, determining the timeliness of the target dynamic password to identify whether a situation that a user is attacked exists or not, and aiming at the situation that the equipment terminal is a code scanning vending device, the scanning graphic code verification stage is a process that the user uses a client to scan the graphic code to request to open a door opening page;

specifically, for the condition of an equipment control request sent by a client based on code scanning operation on a graphic code on an equipment terminal, a target dynamic password carried in the equipment control request meets a preset timeliness condition, namely the graphic code corresponding to the target dynamic password is not invalid, and at the moment, the dynamic password corresponding to the graphic code displayed on the equipment terminal is the target dynamic password;

aiming at the condition that a client sends an equipment control request triggered by a malicious user through an illegal means, a target dynamic password carried in the equipment control request does not meet a preset timeliness condition, namely a graphic code corresponding to the target dynamic password is invalid, and at the moment, a dynamic password corresponding to the graphic code displayed on an equipment terminal is not the target dynamic password;

s203, executing corresponding control operation according to the timeliness judgment result aiming at the target dynamic password, wherein the judgment result can be that the target dynamic password meets the preset timeliness condition or that the target dynamic password does not meet the preset timeliness condition;

specifically, if the target dynamic password meets the preset timeliness condition, it is indicated that the client belongs to a control device terminal which normally actively requests the background server, at this time, the background server needs to normally respond to the device control request, and the control device terminal executes a corresponding control action; if the target dynamic password does not meet the preset timeliness condition, the client is attacked, and the client requests the control equipment terminal from the background server, at this time, the background server needs to return prompt information to the client, for example, the client is triggered to display an error report page.

In one or more embodiments of the present description, a background server controls dynamic update of a graphical code displayed on an equipment terminal, and the graphical code displayed on the equipment terminal is dynamically changed, so that a dynamic password uploaded by a client has certain timeliness, and thus, whether the client is attacked or not can be identified by means of timeliness of the dynamic password, and effective control is performed in time for identifying a situation that the client is illegally attacked by a malicious user, so as to avoid unnecessary loss to a normal user.

As shown in fig. 3, the step S203 of executing a corresponding control operation according to the timeliness determination result for the target dynamic password specifically includes:

if the judgment result is yes, executing S2031, and returning a service page to the client so that the client requests the control target device terminal to the background server based on the service page;

specifically, when the determination result is yes, that is, the target dynamic password satisfies the preset timeliness condition, it is indicated that the client belongs to a device terminal which normally actively requests the control device from the background server, and at this time, the background server needs to normally respond to the device control request, that is, the background server can directly send a control instruction to the device terminal, for example, issue a door opening instruction; in order to further improve the accuracy of the device control, the service data used for rendering the service page can be returned to the client first, so that the user sends the confirmation control information to the client based on the service page displayed by the client, and correspondingly, after the background server receives the confirmation control information, the device terminal is controlled to execute the corresponding control action;

if the judgment result is no, executing S2032, and returning first prompt information to the client so that the client prompts based on the first prompt information;

specifically, for the case that the determination result is negative, that is, the target dynamic password does not satisfy the preset timeliness condition, it is indicated that the client is attacked and requests the background server to control the device terminal, at this time, the background server needs to return the first prompt information to the client to prompt the user that there is a possibility of being attacked currently, in addition, an option for confirming the submission of the device control request may be provided on a display page of the first prompt information displayed by the client, for example, an option for manually submitting a door opening request is provided, so as to prevent the problem that the transaction cannot be performed under the condition that the uploaded target dynamic password is invalid due to the time delay of code scanning of the client.

Further, in order to further improve the accuracy of device control, the method may further return service data for rendering a service page to the client, so that the user sends confirmation control information to the client based on the service page displayed by the client, and based on this, as shown in fig. 4, after the step S2031 returns the service page to the client, the method further includes:

s2033, receiving control confirmation information sent by a client terminal aiming at a displayed service page, wherein the service page can be a door opening confirmation page aiming at the condition that an equipment terminal is a code scanning vending device, sending confirmation door opening information to a background server terminal after the client terminal detects that a user clicks a door opening option on the door opening confirmation page, and sending confirmation unlocking information to the background server terminal aiming at the condition that the equipment terminal is a code scanning rental product;

s2034, sending a control instruction to the target device terminal based on the received control confirmation information, so as to enable the target device terminal to execute a corresponding control action, where the control instruction may be a door opening instruction or an unlocking instruction, and correspondingly, the control action executed by the target device terminal may be a door opening operation or an unlocking operation.

The method includes that a background server generates graphic code information including a dynamic password according to a preset rule, and issues the graphic code information to a corresponding device terminal, so that the device terminal displays a graphic code corresponding to the graphic code information, and thus it can be ensured that a graphic code displayed on the device terminal and used for providing scanning of a client is dynamically updated, and thus it is ensured that a target dynamic password carried in a device control request uploaded by the client is dynamically changed, so as to determine what kind of control operation to execute based on timeliness judgment of the target dynamic password in the following process, and specifically, as shown in fig. 5, before the S201 receives the device control request sent by the client, the method further includes:

s204, determining a dynamic password according to at least two of the device identifier of the target device terminal, the identifier key corresponding to the device identifier, and timestamp information, where the device identifier may be a unique identifier pre-allocated to each device terminal, the identifier key may be determined based on the device identifier in a preset manner, the timestamp information may be a current timestamp when the dynamic password is determined, and specifically, the dynamic password may be stored in a key-value database (redis);

s205, generating graphic code information according to the determined dynamic password, wherein the graphic code information can be obtained by splicing a preset URL address and the dynamic password, namely the dynamic password can be added to the tail end of the URL address, and for example, the URL address can be https:// alipay.com/detail.htm;

s206, the generated graphic code information is issued to a target equipment terminal so that the target equipment terminal displays a corresponding graphic code based on the graphic code information, wherein the graphic code information is different because the dynamic passwords generated each time are different, so that the graphic code displayed by the equipment terminal is dynamically updated, and the graphic code can be a two-dimensional code or a bar code;

specifically, in order to reduce the manufacturing cost of the device terminal, the electronic ink label screen may be used as a graphic code display screen, for example, a display screen provided on the device terminal for displaying a graphic code may be reusable.

When scanning a graphic code displayed on a target equipment terminal, a client can analyze a target dynamic password corresponding to the graphic code, then generate an equipment control request based on the target dynamic password, and send the equipment control request to a background server, so that the background server controls the target equipment terminal based on the equipment control request.

Further, in order to improve the efficiency and accuracy of determining the timeliness of the target dynamic password, the method may automatically delete the failed dynamic password, and further determine whether the target dynamic password carried in the device control request exists after receiving the device control request, so as to determine whether the target dynamic password meets a preset timeliness condition, and based on this, as shown in fig. 6, after the step S206 issues the generated graphic code information to the target device terminal, the method further includes:

s207, adding the determined dynamic password into the dynamic password set, and removing any dynamic password from the dynamic password set when the dynamic password meets a preset destruction condition, wherein the preset destruction condition comprises: the dynamic password set comprises at least one valid dynamic password, and the dynamic password set is arranged in a key-value database (redis);

correspondingly, the step S202 of determining whether the target dynamic password carried in the device control request meets the preset timeliness condition specifically includes:

s2021, judging whether a target dynamic password carried in the equipment control request exists in the dynamic password set;

if the judgment result is yes, determining that the target dynamic password meets the preset timeliness condition, and executing the S2031 to return a service page to the client so that the client requests a background server to control the target equipment terminal based on the service page;

if the judgment result is no, determining that the target dynamic password does not meet the preset timeliness condition, and executing the step S2032 to return the first prompt information to the client, so that the client prompts based on the first prompt information.

Specifically, after a certain dynamic password is removed from the dynamic password set, it indicates that the graphic code corresponding to the dynamic password becomes invalid, and the image code displayed on the corresponding device terminal needs to be updated, so that after the dynamic password is removed from the dynamic password set in S207, the method further includes:

generating a new dynamic password, and updating the graphic code displayed on the corresponding target equipment terminal based on the new dynamic password;

specifically, the process of generating a new dynamic password refers to step S204, where after the new dynamic password is generated, graphic code information is generated according to the dynamic password, and the graphic code information is sent to the corresponding target device terminal, so as to update the graphic code displayed on the target device terminal.

Wherein, in the step S204, the determining the dynamic password according to at least two of the device identifier of the target device terminal, the identifier key corresponding to the device identifier, and the timestamp information specifically includes:

and determining a dynamic password according to at least two of the device identifier of the target device terminal, the identifier key corresponding to the device identifier and the timestamp information by using a message digest algorithm, wherein the message digest algorithm can be an md5 encryption algorithm, and specifically, md5 encryption is performed on at least two of the device id, the unique key corresponding to the device id and the timestamp information by using an md5 encryption algorithm to generate a sign field.

Wherein, the step S2034 of sending the control instruction to the target device terminal based on the received control confirmation information specifically includes:

searching whether a dynamic password corresponding to the received control confirmation information exists in the dynamic password set, and specifically, judging whether a corresponding dynamic password exists in the dynamic set again after receiving the control confirmation information sent by the client aiming at the service page;

if so, removing the dynamic password from the dynamic password set, and sending a control instruction to the target equipment terminal;

specifically, after receiving control confirmation information sent by a client terminal aiming at a service page, the background server terminal is required to execute corresponding control operation on an equipment terminal, correspondingly, the dynamic password meets a preset destruction condition, after the dynamic password is destroyed, a new dynamic password is generated aiming at a target equipment terminal displaying a graphic code containing the dynamic password, and the graphic code displayed on the target equipment terminal is updated based on the new dynamic password;

if not, sending a control instruction to the target equipment terminal, or returning second prompt information to the client to prompt the user whether to send an equipment control request to the background server again;

specifically, after the verification is passed in the scanning pattern code verification stage, that is, the target dynamic password carried in the device control request meets the preset timeliness condition, if the client side aims at the control confirmation information sent by the service page to the background server side within the preset time, the target dynamic password corresponding to the device control request should be valid, that is, the target dynamic password exists in the dynamic password set, and if the target dynamic password does not exist in the dynamic password set, it is indicated that the client side does not aim at the control confirmation information sent by the service page to the background server side within the preset time.

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.
