Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of priority from Chinese Patent Application No. 201510218172.0, filed on Apr. 30, 2015, entitled “Method of Offline Identity Authentication, Intelligent Terminal and System Thereof,” which is incorporated herein in its entirety by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The present disclosure relates generally to improving the performance of content authenticating, searching, generating, providing, recommending and/or hosting computer systems and/or platforms by modifying the capabilities and providing non-native functionality to such systems and/or platforms for offline identity authentication of a user. 
       BACKGROUND 
       [0003]    In recent years, with the advanced developments in science and technology, more and more users conduct mobile payments by using applications of third-party payment platforms installed on portable smart mobile terminals, such as, for example, mobile phones, tablet computers and the like. During transactions occurring on or within third-party payment platforms, after choosing a desired commodity, a buyer completes payment for the commodity by using an account registered on the third-party payment platform, and the third-party payment platform notifies the seller that the payment has been made and instructs the seller to deliver the commodity. After the buyer examines the delivered commodity, the buyer notifies the third-party payment platform to transfer the payment to the seller, and upon receiving the notification, the third-party payment platform transfers the payment to the seller&#39;s account. 
         [0004]    Within conventional systems, when a mobile payment is made by using an application of a third-party payment platform, the application of the third-party payment platform needs to be opened, and relevant information such as account, password and the like needs to be input on the mobile terminal. In addition, identity authentication needs to be performed where the mobile terminal is connected to the Internet. However, when a mobile terminal is offline, the identity authentication fails to proceed, resulting great inconvenience in mobile payment. 
       SUMMARY 
       [0005]    In view of the above, the present disclosure provides systems and methods for an offline identity authentication. The disclosed systems and methods enable, during a mobile payment process, the processing of identity authentication without an internet connection, without a need to open an application of a third-party payment platform on a mobile terminal, and without requiring a user to input relevant information such as account and password. Thus, the disclosed systems and methods improve convenience and usability in mobile payment processing. 
         [0006]    According to some embodiments of the present disclosure, an offline identity authentication method is disclosed, comprising the steps of:

A server may also include one or more mass storage devices, one or more power supplies, one or more wired or wireless network interfaces, one or more input/output interfaces, or one or more operating systems, such as Windows Server, Mac OS X, Unix, Linux, FreeBSD, or the like. 
         [0042]    For the purposes of this disclosure a “network” should be understood to refer to a network that may couple devices so that communications may be exchanged, such as between a server and a client device or other types of devices, including between wireless devices coupled via a wireless network, for example. A network may also include mass storage, such as network attached storage (NAS), a storage area network (SAN), or other forms of computer or machine readable media, for example. A network may include the Internet, one or more local area networks (LANs), one or more wide area networks (WANs), wire-line type connections, wireless type connections, cellular or any combination thereof. Likewise, sub-networks, which may employ differing architectures or may be compliant or compatible with differing protocols, may interoperate within a larger network. Various types of devices may, for example, be made available to provide an interoperable capability for differing architectures or protocols. As one illustrative example, a router may provide a link between otherwise separate and independent LANs. 
         [0043]    A communication link or channel may include, for example, analog telephone lines, such as a twisted wire pair, a coaxial cable, full or fractional digital lines including T1, T2, T3, or T4 type lines, Integrated Services Digital Networks (ISDNs), Digital Subscriber Lines (DSLs), wireless links including satellite links, or other communication links or channels, such as may be known to those skilled in the art. Furthermore, a computing device or other related electronic devices may be remotely coupled to a network, such as via a wired or wireless line or link, for example. 
         [0044]    For purposes of this disclosure, a “wireless network” should be understood to couple client devices with a network. A wireless network may employ stand-alone ad-hoc networks, mesh networks, Wireless LAN (WLAN) networks, cellular networks, or the like. A wireless network may further include a system of terminals, gateways, routers, or the like coupled by wireless radio links, or the like, which may move freely, randomly or organize themselves arbitrarily, such that network topology may change, at times even rapidly.

Network access technologies may enable wide area coverage for devices, such as client devices with varying degrees of mobility, for example. 
         [0046]    For example, a network may enable RF or wireless type communication via one or more network access technologies, such as Global System for Mobile communication (GSM), Universal Mobile Telecommunications System (UMTS), General Packet Radio Services (GPRS), Enhanced Data GSM Environment (EDGE), 3GPP Long Term Evolution (LTE), LTE Advanced, Wideband Code Division Multiple Access (WCDMA), Bluetooth, 802.11b/g/n, or the like. A wireless network may include virtually any type of wireless communication mechanism by which signals may be communicated between devices, such as a client device or a computing device, between or within a network, or the like. 
         [0047]    A computing device may be capable of sending or receiving signals, such as via a wired or wireless network, or may be capable of processing or storing signals, such as in memory as physical memory states, and may, therefore, operate as a server. Thus, devices capable of operating as a server may include, as examples, dedicated rack-mounted servers, desktop computers, laptop computers, set top boxes, integrated devices combining various features, such as two or more features of the foregoing devices, or the like. Servers may vary widely in configuration or capabilities, but generally a server may include one or more central processing units and memory.

A client device may also include or execute an application to perform a variety of possible tasks, such as browsing, searching, playing, streaming or displaying various forms of content, including locally stored or uploaded images and/or video, or games (such as fantasy sports leagues). The foregoing is provided to illustrate that claimed subject matter is intended to include a wide range of possible features or capabilities. 
         [0052]    The principles described herein may be embodied in many different forms. The present disclosure provides systems and methods for offline identity authentication. According to the disclosed systems and methods, when a mobile payment is to be processed, authentication of the identity of the user, the user&#39;s device and/or the user&#39;s account can be processed without an internet connection, and without the need to open an application of a third-party payment platform on a mobile terminal. Additionally, the disclosed systems and methods remove the need, as with conventional payment and authentication systems, for inputting relevant payment, identity and/or account information, such as, but not limited to, account and password information. In some embodiments, the identity authentication process discussed herein can proceed as long as a payment trigger message is sent to a first smart terminal (e.g., the terminal initiating the payment process), thereby improving convenience in mobile payment. 
         [0053]    Various non-limiting embodiments of the present disclosure are described hereinafter in detail with references to the accompanying drawings. 
         [0054]      FIG. 1  is a schematic flowchart illustrating a non-limiting embodiment of an offline identity authentication method according to some embodiments of the present disclosure. As illustrated in  FIG. 1 , the process comprises the following steps: 
         [0055]    In Step S 101 : Upon receiving a payment trigger message, a first smart terminal sends broadcast information to a second smart terminal. 
         [0056]    In some embodiments, the first smart terminal and the second smart terminal register their identifier information in a payment system in advance respectively. In some embodiments, a payment account is bound to the first smart terminal in advance. For example, an Alipay® account may be written (e.g., stored) on or in association with the first smart terminal in advance. 
         [0057]    In some embodiments, the first smart terminal can be a smart bracelet or smart watch, or may be any other type of known or to be known portable smart terminal; and the second smart terminal may be a smart terminal (which can be paired to the first device) connecting to a payment system, such as, for example, but not limited to, a smart vending machine. 
         [0058]    When payment is desired, the button on the smart bracelet or smart watch may be pressed to trigger a payment trigger message. 
         [0059]    The broadcast information sent by the first smart terminal to the second smart terminal at least comprises the identifier information of the first smart terminal, wherein the identifier information of the first smart terminal may be, but is not limited to, a device name and/or model of the first smart terminal, and the sent broadcast information may be a Bluetooth low energy (BLE) broadcast. When a payment trigger message is received, the number of broadcast times may be a predetermined, preset or pre-configured amount—for example,  20 . 
         [0060]    In Step S 102 : The broadcast information is received and parsed. 
         [0061]    According to some embodiments, the second smart terminal receives the broadcast information, and upon receiving the broadcast information, the second smart terminal parses the broadcast information and acquires the identifier information of the first smart terminal carried in the broadcast information. 
         [0062]    In Step S 103 : When it is determined that the first smart terminal has been registered in the payment system, a status code is sent to the first smart terminal. 
         [0063]    In this step, according to some embodiments, after the second smart terminal parses the identifier information of the first smart terminal, the second smart terminal, according to a device registration information table acquired in advance from the payment system (wherein the device registration information table comprises the identifier information of the first smart terminal which has been registered in the payment system), traverses (i.e., searches) in the device registration information table the parsed identifier information of the first smart terminal. In some embodiments, if the corresponding registration information has been found in the device registration information table, it is determined that the first smart terminal has been registered in the payment system. In this case, a Bluetooth connection is established between the second smart terminal and the first smart terminal, and then the second smart terminal sends the status code to the first smart terminal via the Bluetooth connection. 
         [0064]    In some embodiments, the device registration information table stored in the second smart terminal may be periodically updated from the payment system. 
         [0065]    In Step S 104 : Upon receiving the status code, the first smart terminal generates an identity authentication password according to system time and a bound payment account. 
         [0066]    Upon receiving the status code, the first smart terminal calls (or executes) an identity authentication password generation algorithm (e.g., HMAC-based One-time Password (HOTP)), and generates the identity authentication password according to the system time and the payment account bound to the first smart terminal. 
         [0067]    In some embodiments, the system time may be the time when the first smart terminal registers in the payment system in advance, or may be the time when the first smart terminal periodically synchronizes the time with the payment system in a network connecting status. 
         [0068]    In Step S 105 : The identity authentication password is returned to the second smart terminal. 
         [0069]    In this step, the first smart terminal returns the generated identity authentication password to the second smart terminal. In some embodiments, the returning of the password may also be implemented via Bluetooth. 
         [0070]    In Step S 106 : The identity authentication password is received. 
         [0071]    The second smart terminal receives the identity authentication password sent by the first smart terminal. 
         [0072]    According to some embodiments, upon receiving a payment trigger message, a first smart terminal of a payment account sends broadcast information carrying identifier information of the first smart terminal to a second smart terminal; once the second smart terminal validates that the identifier information of the first smart terminal has been registered in a payment system, and thus instructing the first smart terminal to generate an identity authentication password and transfer the password to the second smart terminal, the second smart terminal validates the password received by the second smart terminal, such that the password is transferred to an application of the payment system. In this way, in or during a mobile payment process or system, identity authentication may be processed without an internet connection, and without a need to open an application of a third-party payment platform on a mobile terminal. Additionally, identity authentication can be performed without receiving any input of relevant information such as, but not limited to, account and password. In some embodiments, the identity authentication process discussed herein can be performed as long as a payment trigger message is sent to the first smart terminal, which improves the convenience in mobile payment for a user, device and/or system, or some combination thereof. 
         [0073]    According to some embodiments, after the second smart terminal receives the identity authentication password, the second smart terminal can perform a process comprising the steps of: testing, by the second smart terminal, the integrity of the identity authentication password; and upon a successful testing of the integrity of the identity authentication password, breaking, by the second smart terminal, the connection with the first smart terminal; and transferring, by the second smart terminal, the identity authentication password to a payment system application installed in the second smart terminal, such that the payment system application assembles transaction sheet information and sends the information to the payment system. 
         [0074]    As discussed below, the disclosed technical solutions of the present disclosure are described with reference to a specific non-limiting example. 
         [0075]    In the following example technical solution of the disclosed systems and methods, a description is given by using the scenario of identity identification between a smart bracelet and a smart vending machine as an example. However, it should be understood that the technical solution is not limited to such a scenario, as other similar scenarios, whether they are known or are to be known, can implement the disclosed steps without departing from the scope of the instant disclosure. 
         [0076]    In this example, the smart bracelet has been registered in a payment system in advance, and a payment account has been bound to the smart bracelet; the smart vending machine is connected to the payment system in real time, and acquires a device registration information table from the payment system; and an example process of the identity authentication is as follows: 
         [0077]    1. When receiving a payment trigger message, the smart bracelet sends a Bluetooth broadcast message to the smart vending machine, wherein the broadcast message carries the device name of the smart bracelet (for example, bongII: 07 09 62 6f 6e 67 49 49). 
         [0078]    2. The smart vending machine is in a “master” mode, and constantly scans the surrounding environment. When receiving the broadcast message sent by the smart bracelet, the smart vending machine parses the broadcast message, and acquires the device name of the smart bracelet. The smart vending machine searches the device registration information table according to the device name of the smart bracelet, and if the corresponding data is found in the device registration information table, the smart vending machine then establishes a Bluetooth connection with the smart bracelet and sends a status code to the smart bracelet. 
         [0079]    3. Upon receiving the status code, the smart bracelet calls an identity authentication password generation algorithm, such as, but not limited to, HOTP (a one-time password generation algorithm based on HMAC), wherein HMAC (Hash-based message authentication code) generates an 18-digit identity identification password according to the system time and the payment account bound to the smart bracelet; and finally the smart bracelet sends the identity authentication password to the smart vending machine via Bluetooth. 
         [0080]    It should be understood that while the discussion herein references specific algorithms for performing password generation, it should not be construed as limiting, as any known or to be known password generation (or character string generation) algorithm, technique, software or mechanism can be utilized without departing from the scope of the instant disclosure. 
         [0081]    4. Upon receiving the 18-digit identity authentication password, the smart vending machine verifies integrity of the identity authentication password; and after the verification is successful, the identity authentication code is sent to the main board of the smart vending machine via a serial port. In some embodiments, the main board runs the Android® system, and monitors the serial port at all times (it should be understood that while the discussion herein references the 
         [0082]    Android platform, it should not be construed as limiting, as any type of device or operating system (OS) device or server platform is applicable to the disclosed systems and methods). Upon receiving the identity authentication password, the smart vending machine passes the 18-digit identity authentication password to an application of the smart vending machine. 
         [0083]    5. The application of the smart vending machine receives the identity authentication password, assembles a transaction sheet, and submits the sheet to the payment system. After the payment is made in the payment system, the smart vending machine delivers the commodity. 
         [0084]    It should be understood that the offline identity authentication process discussed herein is not only applicable to shopping, but also widely applicable to other scenarios where trusted identity authentication is desired; for example, the implementation (and/or execution) of the disclosed systems and methods can replace using a bank card, a bus card, a door access key, a shopping card and the like.

         [0089]    a first sending unit  204 , configured to send the identity authentication password back to the second smart terminal. 
         [0090]    The first sending unit sends the identity authentication password back to the second smart terminal via Bluetooth. 
         [0091]    In some embodiments, the first smart terminal  20  is a smart bracelet or smart watch, as discussed above (e.g., a wearable smart device). 
         [0092]      FIG. 3  is a schematic structural diagram illustrating a non-limiting embodiment of a second smart terminal  30  according to some embodiments of the present disclosure. 
         [0093]    As illustrated in  FIG. 3 , the second smart terminal  30  comprises: a second receiving unit  301 , configured to receive and parse broadcast information sent by the first smart terminal; 
         [0094]    a parsing unit  302 , configured to parse the broadcast information sent by the first smart terminal, and acquire identifier information of the first smart terminal, wherein the broadcast information carries the identifier information of the first smart terminal, and a payment account is bound to the first smart terminal in advance; 
         [0095]    a second sending unit  303 , configured to send a status code to the first smart terminal when it is determined that the identifier information of the first smart terminal has been registered in a payment system, such that the first smart terminal generates an identity authentication password according to system time and the payment account bound to the first smart terminal. In some embodiments, the second sending unit  303  is further configured to, when it is determined that the identifier information of the first smart terminal has been registered in the payment system, establish a Bluetooth connection between the second smart terminal and the first smart terminal, and send the status code to the first smart terminal; 
         [0096]    a third receiving unit  304 , configured to receive the identity authentication password returned from the first smart terminal. 
         [0097]    As illustrated in  FIG. 4 , the second smart terminal  30  can be further configured to comprise: a testing unit  305 , configured to test integrity of the identity authentication password; and 
         [0098]    a third sending unit  306 , configured to, upon a successful testing of the integrity of the identity authentication password, pass (e.g., communicate) the identity authentication password to a payment system application installed in the second smart terminal, such that the payment system application assembles transaction sheet information and sends the information to the payment system. 
         [0099]    As illustrated in  FIGS. 2-4 , in some embodiments, the present disclosure discloses an offline identity authentication system, which comprises a first smart terminal  20  and a second smart terminal  30 . With reference to  FIGS. 2-4 , inter alfa, it should be understood that the terminal(s) and units discussed herein are non-exhaustive, as additional or fewer terminals and/or units may be applicable to the embodiments of the systems and methods discussed. 
         [0100]    According to some embodiments of the present disclosure, in line with the discussion above respective to the discussion of  FIGS. 1-4 , upon receiving a payment trigger message, a first smart terminal of a payment account sends broadcast information carrying identifier information of the first smart terminal to a second smart terminal; once the second smart terminal validates that the identifier information of the first smart terminal has been registered in a payment system, and thus it instructs the first smart terminal to generate an identity authentication password and transfer the password to the second smart terminal;, the second smart terminal validates the password received by the second smart terminal, such that the password is passed to an application of the payment system. In this way, in and/or during a mobile payment process or system, identity authentication may proceed without an internet connection and without a need to open an application of a third-party payment platform on a mobile terminal. Additionally, the offline authentication process discussed herein removes the need for inputting relevant information, such as, for example, account and password.
