In order to improve the authenticity of the robot pose information and prevent a malicious user from tampering the pose information, the pose sensor transmits the robot pose information to a navigation and routing system in the inventory robot, the navigation and routing system signs the robot pose information and transmits the signed robot pose information to a material inventory module, so that the authenticity and the tamper resistance of the robot pose information are ensured, and the accuracy and the credibility of the corresponding relationship between the robot pose information and the material attribute information are further ensured.

S304, signing the obtained material inventory data by using a prestored private key to obtain signed material inventory data;

specifically, after the material inventory data of the target warehouse is obtained, the material inventory data is not directly uploaded to the cloud server, but the material inventory data is signed first, and then the signed material inventory data is uploaded to the cloud server, so that the cloud server can rapidly and accurately identify whether the material inventory data comes from the inventory robot, and the identity credibility of the inventory robot is verified.

S306, uploading the signed material inventory data to a cloud server, so that the cloud server performs signature verification on the signed material inventory data and uploads the material inventory data passing the signature verification to a block chain.

Specifically, the checking robot side signs the material checking data by using a private key, correspondingly, the cloud server side checks the signed material checking data by using a public key corresponding to the checking robot to identify the authenticity of the material checking data, and then the material checking data passing the check is stored into a block chain in a trusted manner, so that a third-party client side obtains the authentic, trusted and multi-party witnessed material checking data from the block chain, and the material checking data is used as guidance data for subsequent business processing;

specifically, the cloud server receives a data access request of a third-party client, wherein the material access request carries identification information of the third-party client and identification information of target material inventory data, and the cloud server sends the target material inventory data to the third-party client after determining that the third-party client has an access right of the target material data.

In one or more embodiments of the present disclosure, before the inventory data of the target warehouse is uploaded to the cloud service end, the inventory robot performs trusted signature processing on the collected inventory data of the material to obtain signed inventory data of the material, and the cloud service end performs signature verification and trusted chaining on the inventory data of the material under multiple witnesses based on a block chain technology, so as to improve authenticity, security, credibility, and tamper resistance of the inventory data of the material.

Wherein, to the process that cloud server signed signature verification to material inventory data, can introduce intelligent contract, realize carrying out the verification sign of material inventory data under the multi-party witnessing, based on this, as shown in fig. 4, above-mentioned S306, upload material inventory data after signing to the high in the clouds service end to make this high in the clouds service end sign the material inventory data after signing verify and upload the material inventory data that signature verification passes to the block chain, specifically include:

s3061, uploading the signed material inventory data to a cloud server, so that the cloud server performs signature verification on the signed material inventory data by using an intelligent contract deployed in the block chain, and uploading the material inventory data that passes the signature verification to the block chain.

Specifically, after receiving signed material inventory data uploaded by the inventory robot, the cloud server acquires a corresponding public key based on the equipment identification information of the inventory robot through an intelligent contract deployed in a block chain, and performs signature verification on the signed material inventory data based on the public key, wherein the public key is uploaded to the cloud server by the inventory robot in an equipment identity activation stage.

Wherein the intelligent contract is a digitally defined contract capable of automatically executing terms. In the field of blockchain technology, smart contracts refer to computer programs that are triggered, non-tamperproof, and automatically executed based on predetermined events. The intelligent contracts can ensure the reliable execution of all contracts and avoid tampering, repudiation and default. The intelligent contracts need to be instantiated and validated on a state machine in the blockchain after release.

The intelligent contract can be deployed on the block chain in advance, the intelligent contract comprises a contract for automatically executing the checking and signing of the material checking point data, the intelligent contract is used for checking and signing the signed material checking point data uploaded by the checking robot, and the full-flow transparency and multi-party witness without manual intervention can be achieved.

Specifically, in the process of carrying out check signing on the material inventory data based on the intelligent contract, each node on a block chain participates in automatic execution of the intelligent contract, all execution data items (state data and state parameters) generated in the execution process of the intelligent contract are transparent to each node on the block chain, each node on the block chain is controlled to carry out consensus on the execution data items, the obtained consensus check signing execution data of the inventory data is taken as a signature verification result of the material inventory data and is stored in the block chain in an encrypted mode, and all execution data items generated in the execution process of the intelligent contract are stored under the common evidence of each node on the block chain.

The block chain technology has non-tamper-proof property, and the final signature verification result aiming at the material inventory data and the material inventory data passing the verification are written into the block chain after being witnessed by multiple parties, so that the signature verification result uploaded to the block chain and the material inventory data can be guaranteed not to be tampered, and the authenticity of the data is guaranteed; and aiming at the whole process of the material checking and signing of the stock data, the automatic execution is realized through an intelligent contract arranged on the block chain, each checking and signing link has no manual intervention, the information of each checking and signing link is stored on the block chain, and in case that the checking and signing process of the stock data is required to be disclosed as a notarization subsequently, all relevant information in the checking and signing process of the stock data can be directly obtained from the block chain and used as evidence.

In addition, in order to facilitate the third-party client to quickly and efficiently check the required material inventory data so as to serve as decision information for guiding subsequent business processing, the cloud server can also generate a classified material inventory report based on the material inventory data passing the label checking by using an intelligent contract arranged in the block chain, and upload the classified material inventory report to the block chain. Specifically, the material inventory data passing the check and the signature can be classified according to the inventory time information, the material category information, the region information of the material and the like, and a corresponding material inventory report is generated.

When the intelligent contract is implemented, different implementation processes automatically executed by the intelligent contract can be implemented by different intelligent contracts deployed in the block chain. For example, the signed inventory data is signed and verified using a first intelligent contract deployed in the blockchain. And generating a classified material inventory report based on the material inventory data passing the verification and the signing by using a second intelligent contract deployed in the block chain.

Further, in order to facilitate effective verification of the trusted identity of the inventory robot, the equipment identity activation binding is performed on each inventory robot in advance, and the correspondence between the unique identity of the inventory robot and the public key is performed through the cloud server, so that the identity of the inventory robot can be quickly and accurately verified in the subsequent process, and the inventory data uploaded by the inventory robot can be signed and verified, so that the authenticity of the inventory data stored in the block chain under double control is realized, and based on this, as shown in fig. 5, before the step S302 of obtaining the inventory data of the target warehouse, the method further includes:

s308, if the current state of the checking robot is an initialization state, acquiring a public key of the checking robot; and the number of the first and second groups,

specifically, whether the current state of the inventory robot meets a preset condition is judged, wherein the preset condition comprises: before the checking robot leaves a factory, the checking robot is used for the first time, or an enterprise served by the checking robot has changes; if the judgment result is yes, the current state of the checking robot is determined to be an initialization state, namely, the fact that identity activation binding needs to be carried out on the checking robot is stated.

S310, acquiring identity binding information of the checking robot, wherein the identity binding information corresponds to a material attribution party checked by the checking robot;

specifically, in the process of identity activation binding for the checking robot, not only a public key of the checking robot needs to be acquired, but also identity binding information of the checking robot needs to be acquired; aiming at the condition that a target warehouse simultaneously stores material objects of a plurality of material attribution parties, in order to conveniently and accurately classify material inventory data subsequently, each inventory robot corresponds to the material attribution party served by the inventory robot.

S312, generating an equipment identity activation request of the inventory robot based on the acquired identity binding information and the public key;

the equipment identity activation request carries identity binding information of the checking robot, a public key corresponding to the checking robot and a unique identifier of the checking robot; and after the public key and the identity binding information of the inventory robot are obtained, an equipment identity activation request is automatically generated.

And S314, sending an equipment identity activation request to the cloud server, so that the cloud server responds to the equipment identity activation request and uploads the corresponding relation between the identity binding information of the checking robot and the public key to the block chain.

Specifically, an identity activation input module may be set at the inventory robot side, and correspondingly, a trusted signature identity activation service is set at the cloud server, and the identity activation input module in the inventory robot triggers the trusted signature identity activation service in the cloud server to execute an identity activation binding operation for the inventory robot based on the generated device identity activation request, so that block chaining method registration of the inventory robot identity is realized, and identity credibility and non-tamper-resistance of the inventory robot are ensured.

Correspondingly, after receiving the material checking point data uploaded by the checking robot, the cloud server not only performs signature verification on the signed material checking point data based on a public key corresponding to the checking robot, but also performs authenticity verification on the equipment identity of the checking robot based on identity binding information corresponding to the checking robot, and if the data signature verification is passed and the equipment identity verification is passed, the material checking point data is uploaded to a block chain;

specifically, the cloud server side verifies the authenticity of the equipment identity of the checking robot by using the intelligent contract deployed in the block chain based on the identity binding information corresponding to the checking robot, and a corresponding equipment identity verification result is obtained.

In addition, in a process of sending the device identity activation request to the cloud server by the inventory robot, a situation that the device identity binding fails due to the fact that the device identity activation request is not verified may exist, and therefore, the cloud server may also return an identity activation request response result to the inventory robot, where the identity activation request response result includes: the equipment identity binding is successful or the equipment identity binding is failed;

correspondingly, when receiving a feedback result of the equipment identity binding failure, the inventory robot can send an equipment identity activation request to the cloud server again, so that the cloud server responds to the equipment identity activation request again.

Further, considering the situation that the equipment identity binding fails due to the fact that the equipment identity activation request is determined to come from the untrusted checking robot, preferably, the identity activation request response result is prohibited from being returned to the checking robot, so that the untrusted equipment is prevented from sending the equipment identity activation request to the cloud server again;

for the case that the equipment identity binding fails due to network abnormality and the like, preferably, the cloud server returns an identity activation request response result to the checking robot to trigger the checking robot to send an equipment identity activation request to the cloud server again;

therefore, the cloud server responds to the equipment identity activation request, and if the equipment identity binding failure is determined, whether an identity activation request response result is returned to the inventory robot or not is determined according to the reason type of the equipment identity binding failure.

As shown in fig. 6, in the process of acquiring the identity binding information of the inventory robot, in step S310, acquiring the identity binding information of the inventory robot specifically includes:

s3101, scanning an equipment identity graphic code displayed on a warehouse management terminal by using a camera device, wherein the equipment identity graphic code is distributed by a cloud service terminal;

s3102, the scanned equipment identity graphic code is analyzed to obtain identity binding information of the checking robot.

Specifically, the warehouse management terminal may be equipped with a preset application program, and after detecting a trigger operation for the preset application program, the warehouse management terminal automatically generates an equipment identity information acquisition request and sends the equipment identity information acquisition request to the cloud server, and the cloud server returns corresponding equipment identity information to the warehouse management terminal in response to the equipment identity information acquisition request, where the equipment identity information may be dynamic graphic code information or a random character string;

specifically, for example, the device identity information is dynamic graphic code information, and after receiving the dynamic graphic code information returned by the cloud server, the warehouse management terminal displays the corresponding dynamic graphic code, so that the inventory robot scans the dynamic graphic code by using the camera device and acquires the corresponding identity binding information.

The identity binding information (such as a random character string) can be directly input into the checking robot, and the identity binding information can also be transmitted to the checking robot through the warehouse management terminal. Preferably, the process of triggering the cloud server to distribute the dynamic graphic codes is set at the warehouse management terminal, and then the warehouse management terminal transmits the identity binding information of the checking robot to the checking robot, so that the problem that a malicious user randomly triggers the checking robot to send an equipment identity activation request to the cloud server to randomly falsify the real identity of the checking robot due to the fact that the operation environment of the checking robot is a complex material warehouse of personnel can be avoided, and the identity authenticity and the credibility of the checking robot are further improved.

In addition, in specific implementation, in order to further prevent malicious users from using other terminal devices to randomly trigger the inventory robot to send a device identity activation request to the cloud server, the inventory robot acquires target identification information of the warehouse management terminal after detecting a graphic code scanning triggering operation, judges whether the target identification information is consistent with preset identification information, and scans a device identity graphic code displayed on the warehouse management terminal by using a camera if the target identification information is consistent with the preset identification information; specifically, the target identification information may be a unique serial number, a MAC address, or SIM card information of the wireless communication module;

specifically, if it is determined that the target identification information is consistent with the preset identification information, it is indicated that the device identity graphic code required to be scanned currently comes from a preset trusted warehouse management terminal, and a malicious user is prevented from triggering the inventory robot to send a device identity activation request to the cloud server side at will, so that the condition that the identity of the inventory robot is illegally changed maliciously is avoided.

Further, in the case that a target warehouse stores material objects of a plurality of material attribution parties, the cloud server returns a device service enterprise list to the warehouse management terminal after receiving a device identity information acquisition request of the warehouse management terminal; the warehouse management terminal returns a target equipment service enterprise selected based on the equipment service enterprise list to the cloud server, namely a material attribution party served by the inventory robot to be activated by the identity; the cloud server returns the equipment identity information corresponding to the target equipment service enterprise, namely the identity binding information of the inventory robot to the warehouse management terminal, so that the warehouse management terminal transmits the identity binding information to the corresponding inventory robot.

Further, in order to improve the credibility of a public key uploaded by the inventory robot and used for signature verification of inventory data, a process of issuing a digital certificate with public credibility for the inventory robot by a trusted service management platform is added for the generation process of the equipment identity activation request, and only a legal equipment end allows the trusted service management platform to issue a corresponding digital certificate, so that the cloud service end only stores the digital certificate issued by the trusted service management platform to ensure that the inventory data passing the signature verification is uploaded by the legal equipment end, based on which, the S312 generates the equipment identity activation request of the inventory robot based on the acquired identity binding information and the public key, and specifically includes:

step one, a pre-stored public key is sent to a trusted service management platform, so that the trusted service management platform generates a digital certificate containing the public key;

step two, receiving a digital certificate sent by the trusted service management platform;

and thirdly, generating an equipment identity activation request of the inventory robot based on the acquired identity binding information and the received digital certificate.

The digital certificate generated by the public key of the checking robot is issued by a trusted authority, the digital certificate has public credibility, and when the subsequent cloud server binds the equipment identity information of the checking robot, the issuing authority can be analyzed from the digital certificate carried in the equipment identity activation request so as to identify whether the received digital certificate is issued by the trusted authority or not, so that the public key of the checking robot is prevented from being attacked, and the credibility of the public key is improved.

Specifically, each checking robot corresponds to a pair of public key and private key, and the checking robot acquires the public key and the private key distributed by the target server; storing the private key to the local to sign the material inventory data by using the private key; and in the process of sending the equipment identity activation request to the cloud server, transmitting the public key to the cloud server, so that the cloud server records the public key and performs signature verification on the signed material inventory data based on the public key.

Further, in order to further prevent an illegal molecule from sending the device identity activation request to the cloud server, signature processing on the identity binding information is added on the checking robot side, so that the cloud server checks the signed identity binding information after receiving the device identity activation request to determine whether to respond to the device identity activation request, and based on this, the third step generates the device identity activation request of the checking robot based on the acquired identity binding information and the received digital certificate, which specifically includes:

signing the acquired identity binding information by using a prestored private key to obtain signed identity binding information;

and generating an equipment identity activation request of the inventory robot based on the signed identity binding information and the received digital certificate.

Specifically, before sending an equipment identity activation request to a cloud server, the inventory robot signs the identity binding information, and then sends the equipment identity activation request to the cloud server based on the signed identity binding information, so that the cloud server performs credibility verification on the identity binding information carried in the equipment identity activation request after receiving the equipment identity activation request, thereby ensuring that the identity binding relationship of the robot is credible and tamper-proof.

Wherein, to the condition that signs earlier identity binding information and regeneration equipment identity activation request at the check robot side, it is corresponding, need check sign to equipment identity activation request at the high in the clouds server, ensure that robot identity binding relation is credible, tamper-proofing, on this basis, above-mentioned S314, send equipment identity activation request to the high in the clouds server to make this high in the clouds server respond to this equipment identity activation request and upload the corresponding relation between the identity binding information of check robot and the public key to the block chain, specifically include:

and sending an equipment identity activation request to a cloud server, so that the cloud server responds to the equipment identity activation request, checks the signed identity binding information based on a public key acquired from the trusted service management platform, and uploads the corresponding relation between the identity binding information of the inventory robot and the digital certificate to the block chain after the check passes.

Specifically, after receiving an equipment identity activation request sent by an inventory robot, a cloud server acquires a digital certificate corresponding to the inventory robot from a trusted service management platform based on equipment identification information of the inventory robot;

based on the public key in the acquired digital certificate, verifying the signed identity binding information in the equipment identity activation request;

if the identity binding information passes the verification, uploading the corresponding relation between the identity binding information of the checking robot and the digital certificate to a block chain;

and if the identity binding information is not checked and signed, determining that the equipment identity activation request is from the untrusted checking robot, and stopping responding to the received equipment identity activation request.

In addition, after receiving the equipment identity activation request sent by the checking robot, the cloud server can check the digital certificate in the equipment identity activation request, and then check the signed identity binding information by using the public key in the digital certificate passing through the check; based on this, specifically include:

acquiring a signature verification key of a digital certificate corresponding to the inventory robot from a trusted service management platform based on the equipment identification information of the inventory robot, wherein the signature verification key corresponds to a signature key used by the trusted service management platform for signing a public key corresponding to the inventory robot and generating the digital certificate;

based on the obtained signature verification secret key, verifying the digital certificate in the equipment identity activation request;

if the digital certificate passes the signature verification, verifying the signed identity binding information in the equipment identity activation request by using the public key in the digital certificate; specifically, if the digital certificate passes the verification, the digital certificate is trusted, and therefore, the public key in the digital certificate is trusted;

Further, considering that the information on the block chain is credible and non-falsifiable, compared with a credible service management platform, the public key authenticated by the block chain has more public trust, based on which the checking robot can apply public trust authentication for the public key of itself to the block chain first, so as to ensure the public trust of the public key stored on the block chain, and then send an equipment identity activation request carrying the public key after public trust authentication to the cloud service end, based on this, for the generation process of the equipment identity activation request, in order to improve the trust of the public key uploaded by the checking robot for signature verification of the inventory data of goods and materials, a process of returning the link address corresponding to the public key with public trust to the checking robot by the block chain is increased, and only the legal equipment end allows the requesting block chain to perform public trust authentication of the public key and return the corresponding link address, like this cloud end server only stores the public key that the public credibility of block chain authenticated to ensure that the goods and materials stock check data that signature verification passes are that legal equipment end uploaded, on this basis, above-mentioned S312, based on the identity binding information and the public key that acquire, generates the equipment identity activation request of checking the robot, specifically includes:

step one, sending a pre-stored public key to a cloud server, so that the cloud server uploads the public key to a block chain and returns a chain address for storing the public key in the block chain;

receiving a link address corresponding to the public key returned by the cloud server;

and thirdly, generating an equipment identity activation request of the inventory robot based on the acquired identity binding information, the received on-chain address and the local public key.

The public key of the checking robot is subjected to public trust authentication and chaining, and the link address corresponding to the public key is returned by the block chain, so that when the subsequent cloud server binds the equipment identity information of the checking robot, whether the link address carried in the received equipment identity activation request is returned by the block chain can be identified, whether the public key carried in the equipment identity activation request is attacked or not is determined, the public key of the checking robot is prevented from being attacked, and the credibility of the public key is improved.

Further, in order to further prevent an illegal molecule from sending the device identity activation request to the cloud server, signature processing on the identity binding information is added on the checking robot side, so that the cloud server checks the signed identity binding information after receiving the device identity activation request to determine whether to respond to the device identity activation request, and based on the result, the third step generates the device identity activation request of the checking robot based on the acquired identity binding information, the received on-chain address and the local public key, which specifically includes:

and generating an equipment identity activation request of the inventory robot based on the signed identity binding information, the received digital certificate and the local public key.

and sending an equipment identity activation request to a cloud server so that the cloud server responds to the equipment identity activation request, checks the signed identity binding information based on the public key acquired from the block chain, and uploads the identity binding information of the checking robot, the address on the chain and the corresponding relation between the public key to the block chain after the check passes.

Specifically, after receiving an equipment identity activation request sent by an inventory robot, a cloud server acquires a public key corresponding to the inventory robot from a block chain based on equipment identification information of the inventory robot;

based on the obtained public key, carrying out signature verification on the signed identity binding information in the equipment identity activation request;

if the identity binding information passes the verification, uploading the identity binding information of the checking robot, the corresponding relation between the address on the chain and the public key to the block chain;

In addition, after receiving an equipment identity activation request sent by the checking robot, the cloud server can firstly verify the credibility of the linked address and the public key in the equipment identity activation request, and then verify the signed identity binding information by using the public key passing verification; based on this, specifically include:

acquiring a chain address and a public key corresponding to the checking robot from a block chain based on the equipment identification information of the checking robot;

verifying the chained address and the public key in the equipment identity activation request based on the acquired chained address and the public key; specifically, whether the on-chain address and the public key acquired from the block chain are respectively consistent with the on-chain address and the public key in the equipment identity activation request is judged, and if so, the public key carried by the equipment identity activation request is valid;

if the verification is passed, the signed identity binding information in the equipment identity activation request is verified by using a public key carried in the equipment identity activation request; specifically, if the verification is passed, the public key is proved to be authentic and valid;

In addition, if the equipment identity activation request also carries an equipment uniqueness identifier, the cloud server side uploads the correspondence among the uniqueness identifier, the identity binding information and the public key of the checking robot to the block chain after the cloud server side passes the check and the sign.

Specifically, to the process that the inventory robot requests equipment identity activation to the cloud server, after equipment identity activation request is verified, the cloud server uploads the corresponding relation between equipment identification information and the public key to the block chain, wherein, this equipment identification information can include: at least one of a device uniqueness identifier, identity binding information, a serial number of a digital certificate issued by a trusted service management platform, or an on-chain address returned by a blockchain;

correspondingly, in the process of signature verification of the signed inventory data of the goods and materials by the cloud service end based on the public key, because the inventory robot can carry at least one item of the equipment uniqueness identifier, the identity binding information, the serial number of the digital certificate issued by the trusted service management platform or the chain address returned by the block chain as the equipment identification information when uploading the inventory data of the goods and materials to the cloud service end, after receiving the signed inventory data of the goods and materials uploaded by the inventory robot, the cloud service end obtains the public key corresponding to the inventory robot based on the equipment identification information, and then utilizes the public key to carry out signature verification on the signed inventory data of the goods and materials, wherein the type of the equipment identification information carried by the inventory robot when uploading the inventory data of the goods and materials to the cloud service end can be determined based on the type of the equipment identification carried by the inventory robot when requesting the equipment identity activation to the cloud service end to activate the equipment identity In (1).

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 may 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 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. 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.

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.
