Detailed Description
The embodiment of the specification provides a service processing method, a device and equipment based on a block chain.
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
Example one
As shown in fig. 1, an execution subject of the method may be a block link node, where the block link node may be a terminal device or a server, where the terminal device may be a mobile terminal device such as a mobile phone, a tablet computer, or a personal computer. The server may be an independent server, a server cluster including a plurality of servers, or the like. The system architecture related to the embodiments of the present specification may be as shown in fig. 2. The method may specifically comprise the steps of:
in step S102, obtaining the verification information generated by the service authorizer for the service requester, and deploying a first intelligent contract based on the verification information, where the first intelligent contract is used to verify the signed data of the service requester according to the verification information.
The service authorizer may be a party granting a corresponding right to a service requester requesting to execute a certain service, and the service requester may be a party requesting to execute a certain service, and may include, for example, a certain logistics organization and a financial institution, where the logistics organization needs to apply financing to the financial institution based on some reasons, and then for the financing service, the logistics organization may be a service requester, and since the financial institution needs to grant a right to apply financing to the financial institution, the financial institution may serve as a service authorizer. The storage information may be information that needs to be recorded or stored by the service authorizer, so as to be used as a basis in subsequent service disputes or information verification, and the storage information may include various information, such as information related to the service authorizer (e.g., an identifier of the service authorizer, digital IDentity information of the service authorizer, an identifier of the service requester, digital IDentity information of the service requester, and authorization-related information), where the digital IDentity information may include various information, specifically, a DID (Decentralized IDentity, Decentralized IDentity identifier), and the like). The first intelligent contract may be an intelligent contract constructed from warranty information, where the intelligent contract may be a computer protocol intended to propagate, validate, or perform some process in an informational manner, the intelligent contract allowing trusted interactions without third parties, which may be tracked and irreversible, and the first intelligent contract may include protocols on which contract participants may perform rights and obligations agreed upon by the contract participants. The first intelligent contract may include a trigger condition for triggering execution of the first intelligent contract, and a result corresponding to the trigger condition, the first intelligent contract may include one or more trigger conditions, and each trigger condition may correspond to a result, for example, the trigger condition of the first intelligent contract is: the verification information is matched with the data to be verified provided by the service request party, and the corresponding result of the triggering condition is as follows: the service requester's authentication is passed, etc.
In practice, internet-based financial transaction security has been an important issue of financial institution attention, and at present, for internet-based financial transaction security, it is a common practice to use a dedicated hardware device to store a digital certificate that can identify the identity of a service requester (such as a certain enterprise or institution, etc.), and the digital certificate stored in the hardware device is unreadable. In the practical application process, the hardware device may be connected to a device (i.e., a device used by a service requester) for performing an internet financial transaction, so as to sign transmitted information in the internet financial transaction, and a service authorizer (e.g., a financial institution, specifically, a bank, etc.) may verify the signed information to determine identity information of the service requester, thereby implementing a financial-level user identity verification based on a peer-to-peer transaction. For a service requester, with the increase of internet-based services, there are more and more service demands for applying resources (such as financing) for the internet services, and more financial institutions also provide demands for performing verification, signature verification, authorization and the like based on the internet services. Therefore, the above-mentioned methods of identity verification and signature verification based on point-to-point transaction encounter new business challenges, and therefore, it is necessary to provide a technical solution for better processing of identity verification, signature verification, authorization and the like in financial transactions based on the internet. An embodiment of the present specification provides a method capable of implementing the above technical solution, which may specifically include the following:
with the rapid development of electronic commerce, a large number of organizations or enterprises are more and more inclined to adopt an electronic information mode to perform business communication and communication so as to reduce cost and improve competitiveness, and therefore, a business requester can be granted access or execution authority of a certain business by adopting a mode of issuing authorization information or digital certificates and the like, so that the safety of information transmission is improved. In this embodiment of the present specification, based on the digital certificate in the hardware device, the service authorizer may generate a corresponding digital certificate for the service requester, but the digital certificate may not be stored in the hardware device, and may construct a file of the digital certificate in a software or application manner. The service authorization party can verify whether the service request party has the qualification for accessing or executing the service based on the data, if the service request party is determined to have the qualification for accessing or executing the service, a file of the digital certificate can be generated for the service request party, and if the service request party is determined not to have the qualification for accessing or executing the service, a corresponding notification message can be sent to the service request party. The service authorization party can send the generated file of the digital certificate to the service request party, so that when the service request party needs to access or execute the service, corresponding data can be processed through the digital certificate and then sent to the service authorization party.
When the service authorizer sends the generated digital certificate to the service requester, the service authorizer may store the certificate information generated by the service requester in order to verify the signature information corresponding to the digital certificate and store the certificate of the related information corresponding to the digital certificate. For the storage device for storing the certificate-storing information, considering the accuracy of the certificate-storing information and preventing the certificate-storing information from being tampered, a block chain can be constructed, and the certificate-storing information is stored in the block chain. A blockchain is essentially a decentralized database, which is a string of data blocks associated using cryptography, each data block may contain stored data and its associated information (e.g., information that can be used to verify the validity (or anti-counterfeit) of the stored data and generate the next block). The block chain can be well applied to the on-line data tamper-proofing, anti-counterfeiting and traceable directions, and if relevant behavior data in the processes of using, managing, processing and the like of the certificate-storing information is added into the block chain, the certificate-storing information cannot be changed and repudiated. Therefore, the verification information can be maintained through the block chain, and the signed data of the service requester can be verified based on the verification information in the block chain, so that the accuracy of the verification information and the like is ensured.
Based on the above, the block chain node may respond to the relevant processing of the service authorizer and the service requestor to provide relevant services for the service requestor of a certain service processing, and specifically, when the service authorizer sends the generated digital certificate to the service requestor, the service authorizer may also generate the certificate storing information for the service requestor, and the service authorizer may provide the certificate storing information to the block chain link point in the block chain, and the block chain link point may obtain the certificate storing information and may store the certificate storing information in the block chain.
In addition, the block chain link point can also make a core identity and verification rule for the service requester based on the obtained verification information, generate a corresponding intelligent contract (namely a first intelligent contract) based on the core identity and verification rule, and deploy the first intelligent contract in the block chain network where the block chain link point is located, so that the verification information and the corresponding first intelligent contract are stored in the block chain, other organizations or personnel cannot tamper with the verification information and the corresponding first intelligent contract, and the block chain link point can perform core identity and verification on the service requester through the first intelligent contract.
In step S104, a first service request of a service requester is received, where the first service request includes service data and tag data.
The service data may be data related to the service request, for example, the service request is a request for applying a resource credit line (e.g., credit line of loan) to a service authorizer, and the service data may be data required for applying the resource credit line, specifically, the data may be set according to actual conditions, such as the operation condition information of the service requester, the development prospect of the service requester, and the fixed resource owned by the service requester, which is not limited in this specification. The signed data may be data obtained by signing data, which may be signed by the above-mentioned digital certificate, or the like.
In implementation, after obtaining authorization information or a digital certificate for accessing or executing a service provided by a service authorizer, a service requester may make a service request to the service authorizer, specifically, a page related to the service request may be preset, a request entry (which may be embodied in a manner of a key or a hyperlink) for one or more services may be provided in the page, the service requester may open the page through a terminal device, and may enter a page related to a service request of the service through the request entry, the service data and the information related to the identity of the service requester may be input in an input box of information related to the identity of the service and the service requester provided in the page, and after the input is completed, the key in the page may be clicked to submit, at this time, the digital certificate or the authorization information may perform signature processing on the information related to the identity of the service requester, specifically, the digital certificate or the authorization information may include a pair of keys, where the pair of keys may include a public key and a private key, and the private key may perform signature processing on information related to the identity of the service requester to generate signed data, and then the terminal device of the service requester may generate a first service request using the service data and the signed data and the public key in the digital certificate or the authorization information, and may send the first service request to the blockchain node, so that the blockchain node may receive the first service request of the service requester.
It should be noted that, in the above signature processing procedure, in addition to performing signature processing on the relevant information of the identity of the service requester through the private key therein, in practical application, the relevant information of the identity of the service requester can also be subjected to signature processing through the public key therein, and the private key therein is sent to the block chain node and the like through the first service request. In addition, the service data can be signed by the method, so that the safety of the service data in the transmission process is ensured.
In step S106, a first intelligent contract is invoked to verify the signed data, and a verification result is obtained.
In implementation, after receiving the first service request, the block link point may analyze the first service request, extract the signed data and the corresponding key (such as the public key described above), and then, the block link point may invoke the first intelligent contract to verify the signed data, specifically, the first intelligent contract may record the verification information generated by the service authorizer to the service requestor, the block link point may decrypt the signed data through the key to obtain the data content in the signed data, may compare the data content obtained through decryption with the verification information recorded in the first intelligent contract, if the data content obtained through decryption matches with the verification information recorded in the first intelligent contract, it may be determined that the signed data is verified, if the data content obtained through decryption does not match with the verification information recorded in the first intelligent contract, it may be determined that the verification of the tagged data fails, and at this time, a notification message of the failure of the identity verification may be sent to the service requester, so that the service requester may resend the first service request. In addition, a notification message that the verification of the signed data of the service requester fails can be sent to the service authorizer, so that the service authorizer can adjust the risk level of the service requester according to the actual situation, and can notify the service requester in time through other ways to protect the security of the related data and the like, thereby obtaining the verification result of the signed data.
In step S108, if the verification result is a pass, the service data and the signed data are sent to the service authorizer, so that the service authorizer performs secondary verification on the signed data, and performs service processing based on the service data after the verification is passed, thereby obtaining a processing result.
In implementation, the block link point verifies the signed data by calling a first intelligent contract to obtain a corresponding verification result, if the obtained verification result is that the verification is passed, the identity of the service requester is correct, at this time, subsequent related processing can be continuously executed, and the service data and the signed data can be sent to the service authorizer. After receiving the service data and the signed data, the service authorizer can also perform secondary verification on the signed data, namely, the signed data can be decrypted through a key in a digital certificate or authorization information to obtain data content in the signed data, the data content obtained through decryption can be compared with the certificate-storing information, if the data content obtained through decryption is matched with the certificate-storing information, the verification of the signed data can be determined to be passed, and if the data content obtained through decryption is not matched with the certificate-storing information recorded in the first intelligent contract, the verification of the signed data can be determined to be failed.
If the signed data passes the verification, the service authorizer may perform service processing on the service corresponding to the first service request based on the service data to obtain a corresponding processing result, for example, the first service request is a request for applying a credit line of a resource (e.g., credit line of a loan, etc.) to the service authorizer, the service authorizer may determine whether the service requestor can apply for the credit line of the resource and a numerical range of the credit line of the resource that can be applied, based on the service data, if the service authorizer determines that the service requestor cannot apply for the credit line of the resource based on the service data, the corresponding processing result may be generated, if the service authorizer determines that the service requestor can apply for the credit line of the resource based on the service data, the numerical range of the credit line of the resource that the service requestor can apply for may be obtained, and a corresponding processing result can be generated based on the obtained numerical range of the credit line of the resource which can be applied by the service requester. The service authorizer may return the obtained processing result to the blockchain node.
In step S110, the processing result returned by the service authorizer is received, the processing result is returned to the service requester, and a second service request related to the service corresponding to the service data and initiated by the service requester is processed based on the processing result.
The second service request may be a service request related to a service corresponding to the service data, and the second service request may be different from the first service request, for example, the first service request may be a request for applying a credit line of a resource (e.g., a credit line of a loan, etc.) to a service authorizer, and the second service request may be a request for requesting resource support to a block link point or the service authorizer, which may be set specifically according to an actual situation, and this is not limited in this embodiment of the specification.
In implementation, the block link node may receive the processing result returned by the service authorizer, and may return the processing result to the service requestor. Then, the block link point may process a second service request related to the service corresponding to the service data, which is subsequently initiated by the service requester, based on the processing result, specifically, for example, based on the example of step S108, and taking as an example that the second service request may be a request for requesting resource support from the block link point or the service authorizer, if the processing result received by the block link point is that the service requester cannot apply for the credit line of the resource, when the second service request related to the service corresponding to the service data, which is initiated by the service requester, is subsequently received, the second service request may be rejected for processing, and if the processing result received by the block link point is that the service requester can apply for the credit line of the resource, when the second service request related to the service corresponding to the service data, which is initiated by the service requester, is subsequently received, the second service request can be processed based on the value range of the credit line of the resource that can be applied by the service requester, if the value of the resource that needs to be supported in the second service request is within the value range, the resource that needs to be supported can be provided to the service requester, and if the value of the resource that needs to be supported in the second service request is not within the value range, the second service request can be rejected from being processed, and the like.
The embodiment of the specification provides a service processing method, a first intelligent contract is deployed for the verification information generated by a service requester through a service authorizer, when a first service request of the service requester is received, the first intelligent contract is called to verify the signed data in the first service request, if the verification is passed, the service data and the signed data are sent to the service authorizer for secondary verification, so that the service requester uploads the signed data to a block chain platform, and the block chain platform performs multi-party data processing (such as data ratio peer-to-peer) on the data, so that the processed data has higher reliability, the possibility of obtaining higher authority from the service authorizer is improved, financial verification and signature verification are performed on the service requester through the block chain platform, and the data transmitted between the service authorizer and the service requester is safer, and the second service request which is initiated by the service requester and related to the service corresponding to the service data can be processed based on the processing result of the service authorizer, so that the risk of service processing (such as financing) is reduced, and the safety and the reliability of the service processing are improved.
Example two
As shown in fig. 3, an execution subject of the method may be a block link node, where the block link node may be a terminal device or a server, where the terminal device may be a mobile terminal device such as a mobile phone, a tablet computer, or a personal computer. The server may be an independent server, a server cluster including a plurality of servers, or the like. The method may specifically comprise the steps of:
in step S302, the verification information generated by the service authorizer for the service requester is obtained, and a first intelligent contract is deployed based on the verification information, where the first intelligent contract is used to verify the signed data of the service requester according to the verification information.
For a specific processing procedure of step S302, reference may be made to relevant contents in the first embodiment, which is not described herein again.
In addition, based on the related content in the first embodiment, the service authorizer may generate a digital certificate for the service requester, and in this case, the following steps a 2-a 6 may be performed.
In step a2, a digital certificate generated by the service authorizer for the service requester is obtained, and the digital certificate is used for generating the tagging data.
The digital certificate is a digital certificate for marking identity information of each party of the transaction in the internet transaction, and can encrypt or decrypt information, data and the like of a user in internet communication, so that the integrity and the safety of the information and the data are ensured. The basic architecture of a digital certificate is a pair of keys through which encryption and decryption can be performed, where the keys may include a private key and a public key, the private key may be used for signature and decryption, and the public key may be used for signature verification and encryption, etc.
In implementation, a service requester may apply for access or execution authority of a certain service to a service authorizer, the service authorizer may obtain relevant data of the service requester, and may verify whether the service requester has the qualification for accessing or executing the service based on the data, and if it is determined that the service requester has the qualification for accessing or executing the service, a digital certificate may be generated for the service requester, and the generated digital certificate may be sent to the service requester. In addition, the service authorizer may also send the generated digital certificate to the blockchain node, so as to store the digital certificate, or the blockchain node may query the newly created digital certificate to the service authorizer at regular or irregular time, and may pull the newly created digital certificate from the terminal device of the service authorizer, so that the blockchain node may obtain the digital certificate generated by the service authorizer for the service requester.
In step a4, digital identity information of a service requester is obtained.
The digital identity information may refer to information that a service requester or a service authorizer can be depicted in an identifiable manner through digital information, that is, the digital identity information is represented in a form of concentrating real identity information into a digital code, so as to bind, query and verify the personal real-time behavior information of the service requester or the service authorizer. The digital identity information may not only include identity code information such as birth information, individual description, and biological characteristics of a service requester or a service authorizer, but also relate to personal behavior information (such as transaction information or entertainment information) with various attributes. The digital Identity information can be presented in various ways, such as DID (Decentralized Identity) and the like.
In step a6, the digital certificate is stored in association with the digital identity information of the service requester.
In implementation, the digital certificate may be associated with digital identity information of a service requester, and the digital certificate may be stored in correspondence with the digital identity information of the service requester. In practical application, the service authorizer may issue one or more digital certificates for each service requester, and different service authorizers may also issue one or more digital certificates for each service requester, and each digital certificate issued by the service authorizer may be associated with digital identity information of the service requester and may be correspondingly stored in the blockchain.
Based on the related content, the certificate information may include one or more of the following: in practical applications, the certificate storage information may include various other information besides the above information, and may be specifically set according to practical situations, which is not limited in this specification.
In step S304, a first service request of a service requester is received, where the first service request includes service data and tag data.
The first service request may be a resource application request, and the resource application request may be a request for applying a credit line of a certain resource to a service authorizer, specifically, such as a financing request. The signed data may be data obtained by signing, through a digital certificate, related information (e.g., information related to the service requester) provided by the service requester.
In step S306, a first intelligent contract is invoked to verify the signed data, and a verification result is obtained.
In step S308, if the verification result is that the data is passed, the service data and the signature data are sent to the service authorizer.
In practical applications, in addition to verifying the signed data, other data in the first service request may also be verified, and an optional processing manner is provided below, which may specifically include the following processing of step S310 and step S312.
In step S310, a first intelligent contract is invoked to perform authenticity verification on the service data, so as to obtain a verification result of the service data.
In implementation, the first intelligent contract may further be provided with a rule for performing authenticity verification on the service data in the first service request, when the block link point invokes the first intelligent contract to verify the signed data, and after the verification passes, the first intelligent contract may be invoked again, and the authenticity verification on the service data is performed according to the rule for performing authenticity verification on the service data in the first service request, which is set in the first intelligent contract, specifically, for example, the block link point may obtain data related to the service data of the service requester from the service requester and other trusted information sources, and may compare or match the obtained data with the service data according to the rule for performing authenticity verification on the service data in the first service request, which is set in the first intelligent contract, and finally, the verification result of the service data can be obtained. For example, the service requester is a network freight mechanism, and the corresponding service data may be data such as waybills and logistics, and the like, so that the block link point may obtain data related to the waybills, logistics, and the like of the service requester from the service requester and other trusted information sources, and may match or compare the obtained data with the service data, thereby determining the authenticity of the service data provided by the service requester, and at the same time, may also determine the operation state, and the like, of the service requester, and may use the determined information as a basis for subsequent processing.
In step S312, the verification result of the service data is sent to the service authorizer, so that the service authorizer performs secondary verification on the signed data, and performs service processing based on the verification result of the service data and the service data to obtain a processing result.
In implementation, since the block chain node has verified the authenticity of the service data provided by the service requester, and the verification result has high reliability, after the service authorizer passes the secondary verification of the tagged data, the service authorizer may perform service processing on the service corresponding to the first service request based on the verification result of the service data and the service data to obtain a corresponding processing result, and the specific processing process may refer to the relevant content of step S108 in the first embodiment, which is not described herein again.
In step S314, the processing result returned by the service authorizer is received, and the processing result is returned to the service requestor.
In practical applications, after the processing result, the processing may further process a service request related to the service corresponding to the service data, which is initiated by the service requester, based on the processing result, and specifically may include the following processing in step S316 and step S318.
In step S316, a second intelligent contract is generated according to the processing result and the processing rule of the service corresponding to the service data, and the second intelligent contract is deployed in the blockchain.
For example, the first service request is a resource application request, and the processing rule may include a resource usage rule (e.g., a maximum amount of usage for each time, a time for usage, etc.), and a usage rule of a resource to be applied (e.g., a usage range or a domain of the resource, etc.). The second intelligent contract may be an intelligent contract different from the first intelligent contract, and in practical applications, the second intelligent contract and the first intelligent contract may be combined into one intelligent contract for use, which is not limited in this specification.
In implementation, the block link point may determine, for a service corresponding to the service data, a processing rule of the service corresponding to the service data, generate a corresponding intelligent contract (i.e., a second intelligent contract) based on the processing result and the processing rule of the service corresponding to the service data, and deploy the second intelligent contract into the block link network where the block link point is located, where the block link point processes, through the second intelligent contract, a second service request related to the service corresponding to the service data, which is initiated by a service requester.
In step S318, when a second service request related to the service corresponding to the service data and initiated by the service requester is received, a second intelligent contract is invoked to process the second service request, and the obtained processing result of the second service request is sent to the service authorizer and the service requester.
The second service request may be a resource withdrawal request, and the resource withdrawal request may be a request for withdrawing a certain resource quota from a credit quota of the resource that has been applied, for example, if the credit quota of the resource that has been applied is 10 ten thousand yuan, the resource withdrawal request may be a request for withdrawing 5 ten thousand yuan from the credit quota.
In implementation, after obtaining the processing result, the service requester may perform a service request to the block link node or the service authorizer, and specifically, a related page of the service request may be preset, where the page may be provided with a request entry for one or more services, and the service requester may open the page through the terminal device, and may enter a related page of a corresponding service (such as a resource supporting service) through the request entry, and may generate a second service request through information input by the service requester in an input box of information in the page, and may send the second service request to the block link node, so that the block link node may receive the second service request of the service requester.
After receiving a second service request related to the service corresponding to the service data, initiated by the service requester, the block link point may invoke a second intelligent contract to process the second service request, and send the obtained processing result of the second service request to the service authorizer and the service requester, specifically, the second service request may be a resource support request, and the second service request may include the number of resources to be supported, at this time, the block link point may compare the number of resources to be supported, included in the second service request, with the credit line of the resources already applied, and if the number of resources to be supported is less than or equal to the credit line of the resources already applied, may send the second service request to the service authorizer, so that the service authorizer transfers the resources to be supported to the service requester, if the quantity of the resources needing to be supported is larger than the credit limit of the applied resources, the resource supporting processing can be refused to be executed to the service requester, and meanwhile, corresponding notification messages can be sent to the service requester and the service authorizer.
The embodiment of the specification provides a service processing method, a first intelligent contract is deployed for the verification information generated by a service requester through a service authorizer, when a first service request of the service requester is received, the first intelligent contract is called to verify the signed data in the first service request, if the verification is passed, the service data and the signed data are sent to the service authorizer for secondary verification, so that the service requester uploads the signed data to a block chain platform, and the block chain platform performs multi-party data processing (such as data ratio peer-to-peer) on the data, so that the processed data has higher reliability, the possibility of obtaining higher authority from the service authorizer is improved, financial verification and signature verification are performed on the service requester through the block chain platform, and the data transmitted between the service authorizer and the service requester is safer, and a second intelligent contract is generated based on the processing result of the service authorizer and the processing rule of the service corresponding to the service data, and the second service request related to the service corresponding to the service data and initiated by the service requestor is processed through the second intelligent contract, so that the risk of service processing (such as financing) is reduced, and the safety and reliability of the service processing are improved.

Based on the same idea, the service processing device provided in the embodiment of the present specification further provides a service processing system, as shown in fig. 2 or 9.

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 Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (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.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the various elements may be implemented in the same one or more software and/or hardware implementations in implementing one or more embodiments of the present description.
As will be appreciated by one skilled in the art, embodiments of the present description may be provided as a method, system, or computer program product. Accordingly, one or more embodiments of the present description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, one or more embodiments of the present 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.
Embodiments of the present description are described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. 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 business processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable business 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 business 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 business 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. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. 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.
