Detailed Description

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

Fig. 1 is a schematic view of an application scenario of a transaction processing method according to one or more embodiments of the present specification, as shown in fig. 1, the scenario includes: a terminal device, a transaction processing node and a blockchain of a first user; the terminal equipment of the first user can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like; the terminal equipment of the first user is in communication connection with the transaction processing node through a wireless network.

Specifically, the terminal device of the first user sends a transaction request to the transaction processing node in response to the transaction operation of the first user; the transaction request comprises transaction information of a transaction between a first user and a second user; the transaction processing node determines transaction elements associated with the transaction according to the transaction information; the transaction processing node locks the determined transaction element, performs transaction rollback processing when the locking processing fails, and sends transaction failure information to the terminal equipment of the first user; wherein, the relevant record information of the transaction is stored in the block chain. Therefore, when the transaction processing node receives a transaction request, the transaction elements related to the transaction are firstly locked rather than directly processed, and transaction failure caused by the fact that a certain transaction element does not meet transaction conditions can be effectively avoided; when the locking processing fails, transaction rollback processing is carried out, and the locked transaction elements can be released timely without influencing the transaction elements to participate in other transactions; moreover, the related record information of the transaction is stored in the block chain, so that the traceability of the transaction is ensured, and an effective data basis is provided for the related processing of the transaction.

Further, in one or more embodiments of the present specification, the transaction processing node may be a first blockchain node in a blockchain, and a schematic application scenario diagram of the transaction processing method is shown in fig. 2.

Further, in one or more embodiments of the present specification, the transaction processing node may also be a transaction platform for processing a transaction, and correspondingly, as shown in fig. 3, an application scenario of the transaction processing method may further include at least one blockchain node (only one is shown in fig. 3).

Based on the application scenario architecture, one or more embodiments of the present specification provide a transaction processing method; fig. 4 is a flow diagram of a transaction processing method provided in one or more embodiments of the present disclosure, where the method in fig. 4 can be executed by the transaction processing node in fig. 1, as shown in fig. 4, and the method includes the following steps:

step S102, receiving a transaction request sent by a terminal device of a first user; the transaction request comprises transaction information of transaction between the first user and the second user, and the related record information of the transaction is stored in the block chain;

the transaction information comprises information such as transaction identification, transaction content and the like, wherein the transaction content comprises commodity information of transaction commodities, commodity quantity, first quantity of resources to be transferred, use information of additional resources and the like; the resource to be transferred can be an entity resource (such as currency) or a virtual resource (such as credit); additional resources such as coupons, red packs, etc.

Step S104, determining transaction elements related to the transaction according to the transaction information;

wherein the transaction elements differ from transaction to transaction; for example, the transaction information includes a milk 1 box of brand X, a first user transfers a first amount of resources to be transferred to a second user, and the like, and the transaction element associated with the transaction is determined to be milk according to the transaction information; as another example, the transaction information includes a milk 1 box of brand X, the first user transfers a first amount of resources to be transferred to the second user, and an additional resource identified as Y, and the transaction element that determines the transaction association from the transaction information includes the milk and the additional resource.

Step S106, locking the determined transaction elements;

and step S108, if the locking processing fails, performing transaction rollback processing and sending transaction failure information to the terminal equipment of the first user.

In one or more embodiments of the present description, when a transaction request is received, a transaction element associated with a transaction is first locked, rather than directly processed, so that a transaction failure caused by a certain transaction element not meeting a transaction condition can be effectively avoided; when the locking processing fails, transaction rollback processing is carried out, and the locked transaction elements can be released in time without influencing the transaction elements to participate in other transactions; moreover, the related record information of the transaction is stored in the block chain, so that the traceability of the transaction is ensured, and an effective data basis is provided for the related processing of the transaction.

Generally, different transaction elements are maintained and managed by different users, such as a merchant for maintaining and managing inventory data of commodities, a publishing user of virtual resources for maintaining and managing the quantity, the valid period and the like of the virtual resources; based on this, as shown in fig. 5, in one or more embodiments of the present specification, step S106 includes:

step S106-2, a transaction element locking request is sent to terminal equipment of a related user corresponding to the transaction element, so that the terminal equipment of the related user returns response data based on the determined first state information of the transaction element, and the transaction element is locked when the first state information represents that the transaction element is in a tradable state; wherein the related users comprise second users;

specifically, locking information of each transaction element is determined according to transaction information, and a transaction element locking request is sent to corresponding terminal equipment of a related user according to the determined locking information and a transaction identifier included in the transaction information; when terminal equipment of a related user corresponding to the transaction element receives a transaction element locking request, determining the transaction element to be locked according to the locking information, and determining first state information of the transaction element to be locked; and returning response data representing the locking operation success or the locking operation failure according to the determined first state information and the transaction identification, and locking the transaction element when the first state information represents that the transaction element is in a tradable state.

For example, the transaction information includes the first user transferring 70 points to the second user and redeeming a coupon identified as Y for brand X milk 1 box provided by the second user; determining transaction elements related to the transaction according to the transaction information to comprise milk and a coupon, determining that locking information of the milk comprises brand X and 1 box, and determining that locking information of the coupon comprises identification Y; according to the transaction identifier and the determined locking information, a transaction element locking request is respectively sent to the terminal equipment of the second user and the terminal equipment of the coupon management user; the terminal equipment of the second user inquires the inventory quantity of the milk of the brand X and uses the inventory quantity as first state information of the milk of the brand X according to the received transaction element locking request, for example, the inquired inventory quantity is zero, the milk of the brand X is determined to be in a non-tradable state, and response data representing locking operation failure are returned; further, when the terminal device of the coupon management user receives the transaction element locking request, whether the coupon identified as Y is in the valid period and serves as the first state information of the coupon is detected, for example, the coupon is in the valid period, the coupon is determined to be in a tradable state, the coupon is locked so that other transactions cannot use the coupon, the identification Y of the coupon is recorded in association with the transaction identification, and response data representing that the locking operation is successful is returned.

Step S106-4, determining whether transaction conditions of the transaction are met or not according to the received response data, and if yes, determining that the locking processing is successful; if not, determining that the locking processing fails.

Specifically, when each response data represents that the corresponding transaction element locking operation is successful, it is determined that the locking processing is successful, and when at least one response data represents that the corresponding transaction element locking operation is failed, it is determined that the locking processing is failed.

Still by way of example, when the transaction processing node receives response data returned by the terminal device of the second user and response data returned by the terminal device of the coupon management user, the response data is analyzed to obtain response data returned by the terminal device of the second user, which represents that the locking operation fails, and then it is determined that the locking processing fails, and transaction rollback processing is performed and transaction failure information is sent to the terminal device of the first user.

Further, in one or more embodiments of the present description, as shown in fig. 6, if it is determined that the locking process is successful, the following steps are performed:

step S110, transaction processing is carried out according to the transaction information;

step S112, generating transaction success record information according to the transaction information;

and step S114, storing the transaction success record information into the block chain, and sending the transaction success information to the terminal equipment of the first user.

When the transaction is successful, the transaction may be referred to as a forward transaction. By storing the transaction success record information into the block chain, the traceability of the transaction is ensured, and an effective data basis is provided for reverse transaction processing; the reverse transaction is the reverse process of the forward transaction, and if the forward transaction is commodity purchase, the reverse transaction is return commodity, namely return commodity.

In order to avoid excessive operations to the second user in the rollback processing process, in one or more embodiments of the present specification, a first manner is adopted to process a resource to be transferred, that is, a managed account is set in advance, and after a transaction processing node receives a transaction request sent by a terminal device of a first user, the resource is transferred from the resource account of the first user to the managed account, so as to lock the resource. For convenience of description, in the following embodiments, a transaction processing node is taken as a transaction platform, and a block chain node is further included in a transaction processing scene for example; specifically, as shown in fig. 7, after step S102, the method may further include:

step S103-2, transferring a first amount of resources from the resource account of the first user to the designated hosting account;

specifically, when the resource to be transferred is controlled by the trading platform (for example, the resource to be transferred is a credit issued by the trading platform), the trading platform transfers the resource of the first quantity from the resource account of the first user to the designated hosting account according to the account information of the resource account of the first user included in the trading information, so as to lock the resource of the first quantity. When the resource to be transferred is managed and controlled by a designated organization (for example, the resource to be transferred is entity money managed and controlled by a financial organization), the transaction platform sends a resource transfer request to the terminal device of the user of the designated organization according to the transaction information, so that the terminal device of the user of the designated organization transfers the resource of a first quantity from the resource account of the first user to the designated hosting account according to the transaction information and returns a transfer result, so as to lock the resource of the first quantity. It should be noted that, when the resource to be transferred is managed by the designated organization, step S103-2 may be executed simultaneously with step S106-2.

Step S103-4, first resource transfer record information is generated according to the transaction information, and the first resource transfer record is stored in a block chain; wherein the first resource transfer record information comprises a transaction identifier;

specifically, when the transaction platform determines that the transfer of the resource to be transferred is successful, taking a resource account of a first user as a resource transfer-out account, taking a hosting account as a resource transfer-in account, correlating and recording information such as account information of the resource transfer-out account, account information of the resource transfer-in account, first resource transfer time and the like, and determining the recorded information as a first resource transfer record; and sending the first resource transfer record to the block chain node so that the block chain node stores the first resource transfer record information into the block chain.

Corresponding to step S103-2 and step S103-4, as shown in fig. 7, step S108 includes:

step S108-2, if the first resource transfer record information is inquired from the block chain according to the transaction identifier and the transaction success record information is not inquired, transferring a first amount of resources from the escrow account to the resource account of the first user;

specifically, the transaction platform sends a query request to the block chain link points according to the transaction identifier, so that the block chain link points query corresponding record information from the block chain according to the transaction identifier included in the query request, and return the queried record information to the transaction platform; and the transaction platform receives the record information returned by the blockchain node, if the received record information does not comprise the transaction success record information and the last record information is the first resource transfer record information according to the sequence of the time of storing the record information into the blockchain, the transaction rollback processing condition is determined to be met, and a first amount of resources are transferred from the escrow account to the resource account of the first user so as to release the locked first amount of resources of the first user. Or the transaction platform sends a query request to the block chain nodes according to the transaction identifier so that the block chain nodes query corresponding record information from the block chain according to the transaction identifier included in the query request, and if the block chain nodes determine that the queried record information does not include transaction success record information and the last record information is first resource transfer record information according to the sequence of the time of storing the record information into the block chain, the transaction platform sends a query result representing that the transaction rollback processing condition is met to the transaction platform; after receiving the query result sent by the blockchain node, the transaction platform transfers a first amount of resources from the escrow account to the resource account of the first user.

Further, when the resource to be transferred is controlled by the trading platform, the trading platform transfers the resource of the first quantity from the escrow account to the resource account of the first user according to the account information of the resource account of the first user, which is included in the trading information, so as to release the resource of the first quantity. When the resources to be transferred are managed and controlled by the appointed organization, the transaction platform sends a resource release request to the terminal equipment of the user of the appointed organization according to the transaction information, so that the terminal equipment of the user of the appointed organization transfers the resources with the first quantity from the hosting account to the resource account of the first user according to the resource release request, and the resources with the first quantity are released.

Step S108-4, generating second resource transfer record information according to the transaction information, and storing the second resource transfer record information into the block chain;

specifically, the transaction platform determines the escrow account as a resource transfer-out account, determines the resource account of the first user as a resource transfer-in account, performs relevant recording on information such as a transaction identifier, account information of the resource transfer-out account, account information of the resource transfer-in account, second resource transfer time and the like, determines the recorded information as second resource transfer record information, and transmits the second resource transfer record information to the block link point, so that the block link point stores the second resource transfer record information into the block chain, and the rollback processing is traced based on the record information in the block chain in the follow-up process.

And step S108-6, sending transaction failure information to the terminal equipment of the first user.

Further, step S108 may further include: and sending a resource release request to the terminal equipment of the relevant user corresponding to the response data representing the successful resource locking according to the transaction identifier, so that the terminal equipment of the relevant user determines the associated locked transaction element according to the transaction identifier included in the resource release request and releases the locked transaction element.

Therefore, after the transaction platform receives a transaction request sent by the terminal device of the first user, the resources to be transferred are transferred from the resource account of the first user to the hosting account, so that when transaction rollback processing is carried out, only corresponding resources are transferred from the hosting account to the resource account of the first user without participation of a second user, thereby not only reducing operation of the second user and improving experience of the second user, but also improving transaction rollback processing efficiency.

Further, corresponding to the above steps S108-2 to S108-6, as shown in fig. 7, the step S110 includes:

at step S110-2, a first amount of resources is transferred from the escrow account to a resource account of a second user.

Further, step S110 may further include: sending a transaction element processing request to terminal equipment of a related user corresponding to the transaction element according to the transaction identifier so that the terminal equipment of the related user can perform transaction processing on the locked transaction element associated with the transaction identifier; as in the above example, the terminal device of the coupon management user is caused to update the state information of the corresponding coupon and the like by causing the terminal device of the second user to perform stock reduction processing, and causing the second user to perform product delivery processing and the like.

Further, corresponding to the steps S108-2 to S108-6, as shown in fig. 7, the step S112 includes:

and step S112-2, determining the escrow account as a resource transfer-out account, determining the resource account of the second user as a resource transfer-in account, recording information such as the transaction identification, the account information of the resource transfer-out account, the account information of the resource transfer-in account, the third resource transfer time and the like in an associated manner, and determining the recorded information as transaction success record information.

In the first processing mode of the resources to be transferred, the resources of the first user for transaction are locked based on the escrow account, and the record information of the resource locking operation is stored in the block chain, so that the second user is not required to participate in transaction rollback processing, and the transaction rollback processing efficiency is improved; and transaction rollback processing can be traced based on the record information in the blockchain.

In one or more embodiments of the present application, the resource to be transferred may also be processed in a second manner, that is, after it is determined that the locking process of the transaction element is successful, the resource is transferred from the resource account of the first user to the resource account of the second user. Specifically, as shown in fig. 8, after step S102, the method may further include:

step S103-6, storing the transaction identification and the second state information into a first specified database in a correlated manner; wherein the second state information characterizes that the transaction is in a locked processing state of the transaction element;

correspondingly, as shown in fig. 8, step S108 includes:

step S108-8, if the second state information stored in the first appointed database in the correlated mode is inquired according to the transaction identifier and the transaction success record information is not inquired from the blockchain, the transaction identifier and the third state information are stored in the first appointed database in the correlated mode; wherein the third state information characterizes that the transaction is in a transaction failure state;

specifically, the transaction platform determines whether the second state information stored in a correlated manner is inquired from the first designated database according to the transaction identifier, and sends an inquiry request to the block chain link point according to the transaction identifier, so that the block chain link point inquires corresponding record information from the block chain according to the transaction identifier, and returns the inquired transaction record information to the transaction platform; the transaction platform receives the record information returned by the block link points; and if the second state information stored in association is determined to be inquired from the first specified database and the received record information does not include transaction success record information, determining that the transaction rollback processing condition is met, and storing the transaction identifier and the third state information in association to the first specified database. When the corresponding record information is inquired from the block chain according to the transaction identifier, and the inquired record information does not comprise the transaction success record information, the block chain link point can send an inquiry result representing that the transaction rollback processing condition is met to the transaction platform; correspondingly, when the transaction platform receives the query result and determines that the second state information stored in the first appointed database in the correlated manner is queried, the transaction platform stores the transaction identifier and the third state information in the first appointed database in the correlated manner.

And step S108-10, sending transaction failure information to the terminal equipment of the first user.

Further, corresponding to step S108-8 and step S108-10, as shown in fig. 8, the foregoing step S110 includes:

step S110-4, transferring a first amount of resources from the resource account of the first user to the resource account of the second user;

further, corresponding to step S108-8 and step S108-10, as shown in fig. 8, the aforementioned step S112 includes:

step S112-4, determining the resource account of the first user as a resource transfer-in account and determining the resource account of the second user as a resource transfer-out account; and performing associated recording on the transaction identification, the account information of the resource transferred into the account, the account information of the resource transferred out of the account, the fourth resource transfer time and other information, and determining the recorded information as the transaction success recording information.

In the second processing mode of the resources to be transferred, in the locking and rollback processing process of the transaction elements, the transaction platform only records the state information of the transaction request without performing other operations, so that the transaction rollback processing efficiency is improved; and after the transaction is successfully processed, the transaction success record information is stored to the block chain, so that the traceability of the transaction is ensured.

In the two processing modes of the resources to be transferred, after the locking processing is determined to be successful, the corresponding resources are transferred to the second user, and the transaction success record information is stored in the block chain. In another or more embodiments of the present application, the resource to be transferred may also be processed in a third manner, that is, after receiving the transaction request, the resource of the first user for performing the transaction is directly transferred to the second user. Specifically, as shown in fig. 9, after step S102, the method further includes:

s103-8, transferring a first amount of resources from the resource account of the first user to the resource account of the second user;

for a specific implementation of this step, reference may be made to the foregoing implementation of transferring the first amount of resources from the resource account of the first user to the hosting account, which is not described herein again. It should be noted that, when the resource to be transferred is managed by the specified organization, step S103-8 may be executed simultaneously with step S106-2.

S103-10, generating third transaction record information according to the transaction information, and storing the third transaction record information into the block chain; wherein the third transaction record information includes a transaction identification;

specifically, the transaction platform determines the resource account of the first user as a resource transfer-out account and determines the resource account of the second user as a resource transfer-in account; and (4) recording information such as the transaction identification, the account information of the resource transfer-out account, the account information of the resource transfer-in account, the fifth resource transfer time and the like in an associated manner, and determining the recorded information as third transaction record information. It should be noted that, when the locking process fails, the third transaction record information is used as a data basis for the transaction rollback process; when the locking process is successful, the third transaction record information is transaction success record information, and can be used for transaction description.

Corresponding to the above step S103-8 and step S103-10, as shown in fig. 9, step S108 includes:

step S108-12, if the third transaction record information is inquired from the block chain according to the transaction identification, transferring a first amount of resources from the resource account of the second user to the resource account of the first user;

specifically, the transaction platform sends a query request to the block chain link point according to the transaction identifier, so that the block chain link point queries corresponding last piece of record information from the block chain according to the transaction identifier, and sends the queried last piece of record information to the transaction platform; and if the transaction platform determines that the received transaction information is the third transaction record information, transferring the first amount of resources from the resource account of the second user to the resource account of the first user. Or the transaction platform sends a query request to the block chain link point according to the transaction identifier so that the block chain link point queries the corresponding last record information from the block chain according to the transaction identifier, and if the block chain link point determines that the queried last record information is the third transaction record information, a query result representing that the transaction rollback processing condition is met is returned; and after receiving the query result sent by the blockchain node, the transaction platform transfers the first amount of resources from the resource account of the second user to the resource account of the first user. For the process of transferring the first amount of resources from the resource account of the second user to the resource account of the first user, reference may be made to the foregoing process of transferring the first amount of resources from the hosting account to the resource account of the first user, which is not described herein again.

Step S108-14, generating fourth transaction record information according to the transaction information, and storing the fourth transaction record information into a block chain;

specifically, the transaction platform determines the resource account of the second user as a resource transfer-out account and determines the resource account of the first user as a resource transfer-in account; recording information such as the transaction identification, the account information of the resource transfer-out account, the account information of the resource transfer-in account, the sixth resource transfer time and the like in an associated manner, and determining the recorded information as fourth transaction record information; and sending the fourth transaction record information to the block chain link point so that the block chain link point stores the fourth transaction record information into the block chain.

And step S108-16, sending transaction failure information to the terminal equipment of the first user.

Further, corresponding to the above step S108-12 to step S108-16, as shown in fig. 9, the method further includes: if the locking process is successful, executing the following steps:

step S116, the transaction identification and the fourth state information are stored in a second specified database in a related mode; wherein the fourth state information represents that the transaction is in a transaction successful state;

and step S118, sending transaction success information to the terminal equipment of the first user.

The second designated database and the first designated database may be the same database or different databases.

In the third processing mode of the resources to be transferred, after the transaction platform receives the transaction request, the resources are directly transferred from the resource account of the first user to the resource account of the second user, and third transaction record information is stored in the block chain; when transaction rollback processing is carried out, transferring corresponding resources from the resource account of the second user to the resource account of the first user, and storing fourth transaction record information into the block chain; compared with the first processing mode and the second processing mode, the method has the advantages that the managed account is not required to be maintained, the state information in the designated database is maintained only when the transaction is successful, and the operation is relatively simple from the viewpoint; however, during the rollback process, the second user is typically required to confirm the transfer of the resource to the first user, i.e., to participate in the second user.

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

In the 30'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 manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to the software compiler used in program development, but the original code before compiling is also written in a specific Programming Language, which is called Hardware Description Language (HDL), and the HDL is not only one kind but many kinds, such as abel (advanced boot Expression Language), ahdl (alternate Language Description Language), communication, CUPL (computer universal Programming Language), HDCal (Java Hardware Description Language), langa, Lola, mylar, HDL, PALASM, rhydl (runtime Description Language), vhjhdul (Hardware Description Language), and vhygl-Language, which are currently used commonly. 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 that stores 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 embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

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

For convenience of description, the above devices are described as being divided into various units by function, respectively. Of course, the functions of the various elements may be implemented in the same one or more pieces of software and/or hardware in practicing embodiments of the present description.

One skilled in the art will recognize that one or more embodiments of the present description may be provided as a method, system, or computer program product.

Furthermore, the description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.

It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

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

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

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

Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data.

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

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
