Detailed Description

For the purposes of making the objects, technical solutions and advantages of one or more embodiments of the present specification more clear, the technical solutions of one or more embodiments of the present specification will be clearly and completely described below in connection with specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without undue burden, are intended to be within the scope of one or more embodiments herein.

The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.

At present, the two-dimensional code can be applied to a plurality of scenes, such as receiving and paying codes of various APP; the specific services relate to electronic certificate services, public information services, enterprise website link services, personal positioning services, mobile phone application downloading, video entertainment propaganda, logistics tracking management, mobile payment, identity recognition services (such as certificate two-dimensional code anti-counterfeiting and anti-theft), financial anti-counterfeiting identification, commodity information tracing and the like. In the existing two-dimensional code payment, related account information of a user, such as user APP account information or user bank card account information, is usually bound in the two-dimensional code.

Take electronic certificates as an example. The method can replace an entity identity card to prove identity in a part of off-line scenes, and various future certificate electronization is a development trend. Currently, electronic certificates are mainly carried in a two-dimensional code mode, and verification is carried out by code scanning.

The two-dimensional code can be transmitted and leaked in the modes of screenshot, photographing and the like, and the key factor is that the user code spreading is spontaneous, the two-dimensional code can be displayed and checked at any place and any time, and the two-dimensional code can be used once generated, so that the two-dimensional code leakage risk is high.

Although the electronic two-dimensional code certificate has validity period constraint, namely, the code scanning verification cannot be performed after a certain time, the electronic two-dimensional code certificate can be transmitted through screenshot, photographing and other modes. The digital identity scene shows that the identity information is falsified, and the security privacy risk exists.

Taking two-dimension code payment as an example, electronic payment is more and more commonly used in daily life, wherein two-dimension code payment is the most common electronic payment mode. In the existing two-dimensional code payment, real-time payment is mainly carried out through mobile equipment. And generating a two-dimensional code through the APP running on the mobile equipment, calling a bank card account bound by the APP through the two-dimensional code, or calling balance in the APP to pay for order information. However, in the payment process, the user property safety is dangerous because the two-dimension code is stolen and brushed.

The two-dimensional code displayed by the user is generally valid in the order of minutes, which is based on the tradeoff of user convenience (the user may be displayed in advance) and security (the user fails after a certain time). The longer validity period makes the two-dimensional code propagate and reveal the risk further increase.

Currently, aiming at two-dimensional code screen capturing leakage, the conventional method is to trigger the two-dimensional code to fail during screen capturing. However, this approach relies on the network environment to be stable, if the failure operation cannot be completed in the case of a network outage.

In order to solve the drawbacks of the prior art, the present solution provides the following embodiments:

example 1

Fig. 1 is a flowchart of a two-dimensional code scanning method applied to a third party platform according to an embodiment of the present disclosure. From the program perspective, the execution subject of the flow may be a program or an application client that is installed on an application server. The main body related to the scheme comprises a user terminal, scanning equipment and a third party platform. For embodiment 1, the execution subject may be a third party platform, and more specifically, may be a server for business analysis in the third party platform. In practical application, the server for generating the two-dimensional code and the server for analyzing the two-dimensional code to perform service analysis in the third party platform may be the same server or different servers. The third party platform in the scheme can be a platform for opening a service interface for merchants and users.

As shown in fig. 1, the process may include the steps of:

step 110: and acquiring first code information obtained based on the first two-dimensional code displayed on the user terminal scanned by the scanning equipment.

It should be noted that the scanning device may be a device having a code scanning function. For example: a mobile terminal with a code scanning function may be used, for example: cell phone, tablet computer. The scanning device may also scan bar codes and two-dimensional codes, and thus, the scanning device may also be a bar code scanner, two-dimensional code scanner, or the like.

The user terminal may be a cell phone, tablet computer, intelligent wearable device, personal computer, medium-sized computer, computer cluster, etc.

The first two-dimensional code can be a two-dimensional code displayed on the interface of the user terminal, the scanning equipment scans the first two-dimensional code displayed on the interface of the user terminal, the scanned first two-dimensional code is sent to the third party platform, and the third party platform can analyze the first two-dimensional code scanned by the scanning equipment to obtain corresponding first code information.

It should be noted that the first code information may be code information obtained after the third party platform analyzes the two-dimensional code image based on the first two-dimensional code sent by the scanning device, or may be code information obtained after the scanning device analyzes the first two-dimensional code obtained based on the scanning, in other words, the first code information may be generated by the scanning device, or may be generated by the third party platform.

The first code information may be a data sequence corresponding to the first two-dimensional code or a corresponding specific code value.

Step 120: and analyzing the first code information to obtain first characteristic information.

The process of parsing the first code information may be understood as determining feature information for generating the first two-dimensional code from the first code information, where the feature information may represent feature information for generating a random two-dimensional code, so as to prevent other people from generating the same two-dimensional code in a counterfeit manner.

Step 130: acquiring second code information obtained by a second two-dimensional code displayed on the user terminal and scanned by the scanning equipment; the second two-dimensional code is generated based on the first characteristic information.

The second two-dimensional code can be generated according to the characteristic information obtained through analysis in the first two-dimensional code, namely the second two-dimensional code is generated based on the first two-dimensional code, the third party platform can send the second two-dimensional code to the user terminal after generating the second two-dimensional code based on the characteristic information in the first two-dimensional code, the user terminal displays the second two-dimensional code, and the scanning equipment scans the second two-dimensional code displayed on the user terminal to obtain second code information.

The second two-dimensional code displayed on the interface of the user terminal is scanned by the scanning device, the scanned second two-dimensional code is sent to the third party platform, and the third party platform can analyze the second two-dimensional code scanned by the scanning device to obtain corresponding second code information.

It should be noted that the second code information may be code information obtained after the third party platform analyzes the two-dimensional code image of the second two-dimensional code sent by the scanning device, or may be code information obtained after the scanning device analyzes the second two-dimensional code obtained by the scanning device, in other words, the second code information may be generated by the scanning device, or may be generated by the third party platform.

The second code information may be a data sequence corresponding to the second two-dimensional code or a corresponding specific code value.

Step 140: and analyzing the second code information to obtain second characteristic information.

The process of resolving the second code information may refer to the process of resolving the first code information. And will not be described in detail herein.

Step 150: and after determining that the second characteristic information is the characteristic information used for generating the target two-dimensional code, executing corresponding service.

It should be noted that, in this embodiment of the present disclosure, the initial two-dimensional code refers to a two-dimensional code generated by a server in a third party platform, the first two-dimensional code refers to a two-dimensional code displayed by a user terminal, in practical application, the server in the third party platform generates the initial two-dimensional code, the initial two-dimensional code is sent to the user terminal, and the user terminal displays the initial two-dimensional code, so under normal conditions, the essence of the first two-dimensional code is the initial two-dimensional code, but under some special conditions, a situation that the two-dimensional code displayed by the user terminal is inconsistent with the two-dimensional code generated by the server of the third party platform may also occur. Similarly, the second two-dimensional code may represent the two-dimensional code displayed immediately after the user terminal displays the first two-dimensional code, and the target two-dimensional code may represent the second characteristic information generated by the third party platform to generate the target two-dimensional code by analyzing the first characteristic information from the first two-dimensional code, and then generated according to the second characteristic information.

When the second characteristic information is determined to be the characteristic information used for generating the target two-dimensional code, the two-dimensional code obtained by the second scanning of the scanning device can be determined to be generated by the third party platform based on the characteristic information in the two-dimensional code obtained by the first scanning of the scanning device, so that the second code information obtained by the scanning device can be considered to be effective, and corresponding services can be executed, for example: payment services, identity verification tasks, and the like.

It should be understood that the method according to one or more embodiments of the present disclosure may include the steps in which some of the steps are interchanged as needed, or some of the steps may be omitted or deleted.

The method in fig. 1, by acquiring first code information based on a first two-dimensional code displayed on a user terminal scanned by a scanning device; analyzing the first code information to obtain first characteristic information; acquiring second code information obtained by a second two-dimensional code displayed on a user terminal scanned by scanning equipment; analyzing the second code information to obtain second characteristic information; and after determining the second characteristic information to generate the characteristic information used by the target two-dimensional code, executing corresponding service. According to the method, the code scanning equipment can acquire corresponding service data after scanning the code twice continuously, and the two-dimensional code scanned for the second time is generated based on the two-dimensional code scanned for the first time, so that the risk that the two-dimensional code is captured and photographed to leak is effectively avoided, the problem that user information is leaked due to the fact that the two-dimensional code is stolen and brushed is solved, the safety privacy risk is caused, and the safety of scanning the two-dimensional code is improved.

The examples of the present specification also provide some specific embodiments of the method based on the method of fig. 1, which is described below.

Optionally, before the obtaining the second code information obtained by the second two-dimensional code displayed on the user terminal scanned by the scanning device, the method further may further include:

determining characteristic information used for generating a target two-dimensional code based on the first characteristic information;

generating a target two-dimensional code based on the characteristic information used for generating the target two-dimensional code;

and sending the target two-dimensional code to the user terminal.

After the scanning device scans the first two-dimensional code displayed by the user terminal, the first characteristic information can be obtained by analyzing the first two-dimensional code, the third party platform can generate characteristic information used for generating the target two-dimensional code by using the first characteristic information, the target two-dimensional code is generated by using the characteristic information, and the generated target two-dimensional code is sent to the user terminal for displaying. For example: a scanning device of a merchant scans a first two-dimensional code A displayed on a user terminal, analyzes the A to obtain first characteristic information X, generates characteristic information Y based on the first characteristic information X by a third party platform, generates a target two-dimensional code B based on the characteristic information Y, and sends the two-dimensional code B to the user terminal for display.

According to the method, the target two-dimensional code is generated based on the characteristic information obtained by analyzing the two-dimensional code scanned by the scanning equipment for the first time, so that the risk of leakage of the two-dimensional code can be reduced.

Optionally, before determining the feature information used for generating the target two-dimensional code based on the first feature information, the method further includes:

judging whether the first characteristic information is consistent with the characteristic information used for generating the initial two-dimensional code;

the determining, based on the first feature information, feature information used for generating the target two-dimensional code specifically includes:

and when the first characteristic information is consistent with the characteristic information used for generating the initial two-dimensional code, determining the characteristic information used for generating the target two-dimensional code based on the first characteristic information.

In practical application, the third party platform generates the two-dimensional code, the two-dimensional code needs to be sent to the user terminal for displaying, the two-dimensional code scanned by the scanning equipment is the two-dimensional code displayed by the user terminal, and after the scanning equipment scans the two-dimensional code, the corresponding two-dimensional code or code information needs to be sent to the third party platform for processing. Therefore, before determining the feature information used for generating the target two-dimensional code based on the first feature information, it is required to determine whether the first two-dimensional code displayed on the interface of the user terminal by the scanning device is the initial two-dimensional code generated by the third party platform, that is, it is required to determine whether the first feature information parsed from the first two-dimensional code scanned by the scanning device is the feature information for generating the initial two-dimensional code, if the first feature information is the feature information for generating the initial two-dimensional code, it is determined that the first two-dimensional code scanned by the scanning device is the initial two-dimensional code generated by the third party platform, and therefore it is determined that the first two-dimensional code scanned by the scanning device is effective, and therefore, the feature information used for generating the target two-dimensional code can be determined based on the first feature information parsed from the first two-dimensional code. In contrast, if the first feature information is not the feature information for generating the initial two-dimensional code, it may be determined that the first two-dimensional code scanned by the scanning device is an invalid two-dimensional code, and the feature information used for generating the target two-dimensional code may not be determined based on the first feature information. At this time, according to a specific application scenario, the scanning device may be prompted to rescan the correct two-dimensional code, or the user terminal may be prompted to initiate the correct two-dimensional code.

By the method, the two-dimensional code scanned by the code scanning equipment for the first time can be ensured to be the effective two-dimensional code, so that the validity of the generated target two-dimensional code is ensured.

Optionally, before the obtaining the first code information obtained based on the first two-dimensional code displayed on the user terminal scanned by the scanning device, the method may further include:

acquiring the first two-dimensional code scanned by the scanning device;

and decoding the first two-dimensional code to obtain first code information corresponding to the first two-dimensional code.

In this step, the main body of the operation of analyzing the two-dimensional code to obtain the code information is determined as the third party platform, but in practical application, the scanning device may analyze and determine the first code information based on the first two-dimensional code obtained by scanning, and then send the code information to the user terminal.

Optionally, the first feature information is a first random seed, and before the first two-dimensional code scanned by the scanning device is obtained, the method further includes:

generating the first random seed based on a set mode;

generating the initial two-dimensional code based on the first random seed;

and sending the initial two-dimensional code to the user terminal for display so as to be scanned by the scanning equipment.

In the embodiment of the present disclosure, the first feature information may represent feature information obtained by parsing a first two-dimensional code obtained by scanning, the second feature information is feature information obtained by parsing a second two-dimensional code, and the feature information may represent information for distinguishing different two-dimensional codes from feature information for generating a two-dimensional code, for example: random numbers, random seeds, etc.

Among them, random seed (random seed) is a term of art for computer, a random number that targets a random number and is subject to a true random number (seed) as an initial condition. The random number of a general computer is a pseudo random number, a true random number (seed) is used as an initial condition, and then a certain algorithm is used for continuously iterating to generate the random number. Distinction from common random numbers:

random number: the true random number may be generated using physical phenomena such as: such a random number generator is called a physical random number generator, and the true random number generated by the physical random number generator is true random.

The random seed, also called pseudo random number, may be regular, but this regular period is longer, but predictable. The main reason is that the pseudo-random number is simulated by the computer using an algorithm, the process does not involve a physical process, the seed is an initial value, in particular, the seed may be a sequence number, which may be given to a sequence manager, from which a sequence may be taken out of the manager, which may be a random number obtained from the sequence number. The seed and the random number sequence may be considered to be in one-to-one correspondence. For example: { An } = F (x), x is the seed, F () is the algorithm, and { An } is the array of numbers.

The random seed may be generated by a program for generating the random seed by a computer according to a conventional method and a certain calculation formula.

According to the method, the two-dimensional code is generated by using the random seed, so that the uniqueness of the two-dimensional code generated each time can be ensured.

Optionally, determining, based on the first feature information, feature information used for generating the target two-dimensional code may specifically include:

and calculating to obtain a second random seed according to a preset rule based on the first random seed.

In the embodiment of the present disclosure, the feature information used to generate the two-dimensional code may be a random seed, and the random seed for generating the target two-dimensional code may be generated based on the random seed obtained by parsing the first scanned two-dimensional code. Specifically, the manner of generating the second random seed based on the first random seed may be set according to an actual application scenario, and may be generated according to a certain preset rule, so long as it is ensured that the second random seed is related to the first random seed, and the second random seed is generated based on the first random seed.

By the method, the target two-dimensional code can be generated based on the two-dimensional code scanned by the scanning equipment for the first time, namely the scanning equipment needs to scan the two-dimensional code continuously for two times to acquire effective service data, and the target two-dimensional code scanned for the second time needs to be generated based on the two-dimensional code scanned for the first time, so that the safety of scanning the two-dimensional code is improved.

Optionally, the determining that the second feature information is feature information used for generating the target two-dimensional code may specifically include:

judging whether the second characteristic information is the same as the second random seed;

and when the second characteristic information is the same as the second random seed, determining that the second characteristic information is the characteristic information used for generating the target two-dimensional code.

After the scanning device scans the target two-dimensional code, it is required to determine that the second two-dimensional code scanned by the scanning device is an effective two-dimensional code, specifically, it may be determined that the scanned second two-dimensional code is the target two-dimensional code generated by the third party platform based on the first feature information. And further determining second characteristic information obtained by analysis from the second two-dimensional code to generate a second random seed of the target two-dimensional code.

Further, whether the second characteristic information is the same as the second random seed can be judged, if the second characteristic information is the same as the second random seed, the characteristic information used by the second characteristic information for generating the target two-dimensional code can be determined, and the second two-dimensional code scanned by the scanning device is an effective two-dimensional code. At this time, the subsequent business operation may be performed based on the second two-dimensional code scanned by the scanning device. Otherwise, if the second characteristic information is different from the second random seed, it may be determined that the second characteristic information is not characteristic information used for generating the target two-dimensional code, and the second two-dimensional code scanned by the scanning device is an invalid two-dimensional code, so that execution of subsequent corresponding service operations is refused.

It should be noted that, if the server for generating the two-dimensional code and the server for resolving the two-dimensional code are different servers, when determining that the first characteristic information resolved from the first two-dimensional code is consistent with the characteristic information used for generating the initial two-dimensional code, and when verifying the validity of the second two-dimensional code scanned for the second time by the scanning device, the second random seed for generating the target two-dimensional code from the second characteristic information resolved from the second two-dimensional code can be verified a priori, and then the association relationship between the second characteristic information resolved from the second two-dimensional code and the first random seed for generating the initial two-dimensional code is verified to meet the preset rule;

specifically, when the association between the second feature information and the first random seed meets a preset rule, determining that the association verification is passed, and when the association verification is passed, determining that the second two-dimensional code scanned by the scanning device is valid.

By the method, the validity of the second two-dimensional code scanned by the scanning device can be further determined when the servers for generating and analyzing the two-dimensional code are different.

Optionally, after the obtaining the second code information obtained by the second two-dimensional code displayed on the user terminal scanned by the scanning device, the method may further include:

And determining the second two-dimensional code as a failure two-dimensional code.

In practical application, when the third party platform receives the second code information of the second two-dimensional code sent by the scanning device, it can be determined that the scanning device has scanned the newly generated target two-dimensional code, at this time, the third party platform can place the second two-dimensional code displayed on the interface of the user terminal as a failure two-dimensional code, and when any scanning device scans the second two-dimensional code again, no effective two-dimensional code information can be obtained.

By the method, the uniqueness and the safety of the second two-dimensional code can be ensured, and once the second two-dimensional code is successfully scanned once, the second two-dimensional code cannot be scanned for the second time, so that the safety of information corresponding to the two-dimensional code is ensured.

Optionally, after the obtaining the first code information obtained based on the first two-dimensional code displayed on the user terminal scanned by the scanning device, the method may further include:

and determining the first two-dimensional code as a failure two-dimensional code.

However, in practical application, the initial two-dimensional code is a two-dimensional code that does not include user information, and even if the initial two-dimensional code is captured or photographed, the user information is not revealed.

In the method, even if a plurality of scanning devices are used for scanning the first two-dimensional code or the second two-dimensional code, the platform receives the two-dimensional code information which is firstly scanned twice continuously, and then the two-dimensional code is set to be invalid. Therefore, even if a plurality of scanning devices scan the two-dimensional code, information leakage corresponding to the two-dimensional code is not caused.

Fig. 2 is a flowchart of a two-dimensional code scanning method applied to a scanning device according to an embodiment of the present disclosure. From the program perspective, the execution subject of the flow may be a program or an application client that is installed on an application server. The main body related to the scheme comprises a user terminal, scanning equipment and a third party platform. For embodiment 2, the execution subject may be a scanning device.

As shown in fig. 2, the process may include the steps of:

step 210: acquiring a first two-dimensional code displayed by a user terminal; the first two-dimensional code is generated by a third party platform.

Step 220: and scanning the first two-dimensional code to obtain first code information.

Step 230: and sending the first code information to the third party platform.

Step 250: and scanning the second two-dimensional code to obtain second code information.

Step 260: the second code information is sent to the third party platform so that the third party platform can analyze the second code information to obtain second characteristic information; and executing corresponding service after determining the second characteristic information as the characteristic information used for generating the target two-dimensional code.

The third party platform, the user terminal, the scanning device, the first code information, and the second code information in this embodiment are described. The explanation of the terms of the first feature information, the second feature information, and the like is the same as that of embodiment 1, and therefore, the description thereof will not be repeated in this embodiment.

For the scanning equipment, the scanning equipment needs to scan a first two-dimensional code displayed by the user terminal, then the scanned information is sent to a third party platform, the third party platform generates a target two-dimensional code based on the first scanned information, the target two-dimensional code is sent to the user terminal for displaying, and the scanning equipment performs second scanning.

It should be noted that, because the scanning device scans the code twice continuously, the validity period of the two-dimensional codes can be further reduced, and optionally, the validity period can be shortened to a second level, thereby reducing the possibility of being falsely used after the two-dimensional codes are revealed.

Example 3

Fig. 3 is a flowchart of a two-dimensional code display method applied to a user terminal according to an embodiment of the present disclosure. From the program perspective, the execution subject of the flow may be a program or an application client that is installed on an application server. The main body related to the scheme comprises a user terminal, scanning equipment and a third party platform. For embodiment 3, the execution subject may be a user terminal.

As shown in fig. 3, the process may include the steps of:

step 310: and sending a two-dimensional code display request to a third party platform.

It should be noted that, the two-dimensional code display request may represent a request for displaying a two-dimensional code sent by the user terminal to the third party platform, and after the third party platform receives the request, a random seed is generated according to a preset mode, and then a first two-dimensional code is generated based on the random seed and sent to the user terminal for displaying.

Step 320: and acquiring a first two-dimensional code sent by the third party platform based on the two-dimensional code display request.

Step 330: and displaying the first two-dimensional code so as to enable the scanning equipment to scan the first two-dimensional code to obtain first code information, and sending the first code information to the third party platform.

Step 340: acquiring a second two-dimensional code sent by the third party platform; the second two-dimensional code is a target two-dimensional code generated based on first characteristic information corresponding to first two-dimensional code information after the third party platform obtains the first code information obtained based on the first two-dimensional code scanned by the scanning equipment.

Step 350: and displaying the second two-dimensional code, so that the scanning equipment scans the second two-dimensional code to obtain second code information, and sending the second code information to the third party platform.

The interaction between the execution bodies in the embodiment of the present solution described above may be described with reference to fig. 4.

Fig. 4 is a system interaction flowchart of a two-dimensional code scanning method provided in an embodiment of the present disclosure.

As shown in fig. 4, the interaction subject may include a executive subject user terminal, a third party platform, and a merchant, and the interaction flow may include the steps of:

the method comprises the following steps: the third party platform generates a random seed X according to a preset mode, and generates an initial two-dimensional code based on the random seed X.

Step 404: and sending the initial two-dimensional code to a user terminal for display.

Step 406: the user terminal presents the initial two-dimensional code to the merchant.

Step 408: and the merchant scans the initial two-dimensional code displayed by the user terminal to obtain a code string A.

Step 410: the merchant sends the code string a to the third party platform.

Step 412: and the third party platform analyzes the code string A to obtain a random seed X1.

Step 414: and judging whether the X1 is effective or not, if so, generating a random seed Y based on the X1, and generating a target two-dimensional code based on the random seed Y.

Step 416: and sending the target two-dimensional code to the user terminal.

Step 418: and the user terminal displays the target two-dimensional code to the merchant.

Step 420: and scanning the target two-dimensional code by the merchant to obtain a code string B.

Step 422: the merchant sends the code string B to the third party platform.

Step 424: and the third party platform analyzes the code string B to obtain a random seed Y1.

Step 426: and judging whether Y1 is effective or not, and executing the subsequent business process.

Step 428: and sending the corresponding business data to the merchant.

Step 430: setting the target two-dimensional code as a failure two-dimensional code.

It should be noted that, the server of the third party platform caches the ID of the user terminal and the random seed X for generating the initial two-dimensional code, and when generating the random seed Y, the random seed X is found based on the cached ID of the user terminal, so as to generate the random seed Y.

By the method, the following technical effects can be achieved:

1) The two-dimensional code spontaneously displayed by the user is an initial two-dimensional code, and the initial two-dimensional code has no availability (namely, the service can not be completed through the initial two-dimensional code), so that the initial two-dimensional code is photographed and the screenshot can not reveal user information.

2) The really available target two-dimensional code is generated by a platform based on the first two-dimensional code only after a merchant scans the code for the first time, so that the probability of being captured and photographed is greatly reduced.

3) The two scanning codes of the merchant are continuous, the time interval is short, and the risk of leakage of the two-dimensional code is further reduced.

4) The validity period of the target two-dimensional code is short, the target two-dimensional code can be shortened to a second level, and the target two-dimensional code can be invalid once the merchant scans, so that the possibility of being impossibly used after the two-dimensional code is revealed can be reduced.

5) The security and the uniqueness of the user spreading code are ensured through the association relation of the random seeds X, Y; through two-stage code scanning of two-dimensional code, prevent that the two-dimensional code from being propagated through the mode of taking a picture and revealing.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments. In particular, for the apparatus embodiments, since they are substantially similar to the method embodiments, the description is relatively simple, and reference is made to the description of the method embodiments in part.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (ProgrammableLogicDevice, PLD) (e.g., field programmable gate array (FieldProgrammableGate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. The designer programs itself to "integrate" a digital system onto a single PLD without requiring the chip manufacturer to design and fabricate application specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (HardwareDescriptionLanguage, HDL), and HDL is not only one but a plurality of kinds, such as ABEL (AdvancedBooleanExpressionLanguage), AHDL (AlteraHardwareDescription Language), confluence, CUPL (cornelluniversal programming language), HDCal, JHDL (javahard script language), lava, lola, myHDL, PALASM, RHDL (Ruby HardwareDescriptionLanguage), etc., VHDL (Very-High-SpeedIntegrated CircuitHardwareDescriptionLanguage) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of 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, application specific integrated circuits (ApplicationSpecificIntegratedCircuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmelAT91SAM, microchipPIC F26K20 and silicane labsc8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.

The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
