背景技术
目前，利用终端(如手机)的近场通信(Near Field Communication，NFC)功能，将手机等终端模拟成公交卡，以通过“刷手机”的方式乘坐公共交通工具的方法已经出现，如图1所示。
一般的，实现模拟公交卡的终端至少需要具备以下三个硬件单元：NFC前端芯片、NFC天线、安全芯片。其中，NFC前端芯片和NFC天线用于实现NFC通信，公交卡的账户标识和账户余额以硬件加密的形式存储于安全芯片中，也就是说，安全芯片的作用是防止账户余额被非法修改。
使用时，用户将终端贴近公共交通工具的收款设备，收款设备就会与终端建立NFC连接，收款设备有权限通过NFC连接改写终端中的安全芯片存储的账户余额(例如将100元改写为98元)，以收取乘车费。
基于现有技术，需要一种成本更低的支付乘车费的方法。
发明内容
本说明书实施例提供一种支付乘车费的方法及装置，以解决现有的支付乘车费的方法成本较高的问题。
为解决上述技术问题，本说明书实施例是这样实现的：

具体实施方式
如背景技术所述，目前的用户终端需要具备NFC前端芯片、NFC天线以及安全芯片等硬件单元，用户才能通过“刷手机”的方式乘坐公共汽车、地铁等公共交通工具。
但是，以用户终端是手机为例，一方面，要求手机具备安全芯片会导致手机的硬件成本过高；另一方面，市面上依然存在很多不具备安全芯片的手机，这些手机的用户无法享受“刷手机”乘坐公共交通工具的便利。
为此，在本说明书实施例中，一方面，用户终端不会存储用户的账户余额，而是由服务器对用户的账户进行维护；另一方面，不论用户终端是否具备安全芯片，都可以利用用户终端具备的NFC前端芯片和NFC天线，使用户终端与公共交通工具的收款设备建立NFC连接，由用户终端将用户的账户标识传输给收款设备，再由收款设备请求服务器对所述账户标识对应的账户进行扣款。
为了描述的方便，下文以公共交通工具是地铁为例展开说明。
为了使本技术领域的人员更好地理解本说明书中的技术方案，下面将结合本说明书一个或多个实施例中的附图，对本说明书实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本说明书一部分实施例，而不是全部的实施例。通过本说明书实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本说明书保护的范围。
以下结合附图，详细说明本说明书各实施例提供的技术方案。
图2是本说明书实施例提供的支付乘车费的方法流程图，包括以下步骤：
S200：用户终端与公共交通工具的收款设备建立近场通信NFC连接。
在本说明书实施例中，用户终端可以是手机、平板电脑、笔记本电脑等能够应用于移动支付场景的智能设备。而公共交通工具的收款设备可以是地铁闸机、公共汽车上的刷卡器等，下文以收款设备是地铁闸机为例说明。
在本步骤中，用户可以将用户终端贴近收款设备，当用户终端和收款设备的距离不大于NFC感应距离时，用户终端和收款设备方可建立NFC连接。
需要说明的是，NFC连接的建立并不依赖于互联网或局域网，因此，用户终端和收款设备均离线时，二者依然可以建立NFC连接。
S202：用户终端根据与公共交通***预先约定的加密算法，对用户的账户标识进行加密，得到加密数据。
S204：用户终端通过所述NFC连接，将所述加密数据传输给所述收款设备。
在本说明书实施例中，为了防止用户的账户标识在传输过程中被不法分子截获，用户终端可以对用户的账户标识进行加密，通过NFC连接将加密数据传输给收款设备。这样的话，哪怕加密数据在传输过程中被不法分 子截获，不法分子也无法解密得到用户的账户标识。
需要说明的是，在步骤S102中，用户终端对账户标识进行加密所使用的加密算法，可以是仅适用于用户终端与公共交通工具的收款设备进行数据传输的加密算法。此加密算法可以由用户终端上安装的支付应用执行，支付应用和公共交通***(如地铁公司的服务器)可以预先对加密算法进行约定。
S206：收款设备通过所述NFC连接，接收所述用户终端传输的加密数据。
S208：收款设备对所述加密数据进行解密，得到所述账户标识。
S210：将所述账户标识发送给服务器，进行扣款。
在本说明书实施例中，收款设备对加密数据进行解密后，方可获取账户标识。随后，收款设备可以将解密得到的账户标识发送给服务器，服务器就可以从账户标识对应的账户中进行扣款。
其中，当用户终端上安装有支付应用，且由支付应用执行对账户标识的加密时，所述服务器是所述支付应用对应的服务器。
此外，当用户要乘坐的地铁是分段计费的模式时，收款设备在用户进站和用户出站(用户乘坐公共汽车时，可以是用户上车和下车时)时，都需要通过NFC连接获取用户终端传输的加密数据，在用户进站时，收款设备根据解密得到的账户标识进行记录，当用户出站时，收款设备根据解密得到的账户标识计算乘车费，并将账户标识和乘车费一并发送给服务器，服务器方可从账户标识对应的账户中扣除乘车费。
当用户要乘坐的地铁是统一计费(假设不论乘坐多少里程，统一计费2元)的模式时，收款设备仅需在用户进站时获得账户标识，将账户标识发送给服务器，服务器从账户标识对应的账户中扣除2元乘车费。
在现有的支付乘车费的方法中，具有NFC前端芯片、NFC天线、安全芯片这三个硬件单元的用户终端相当于一张公交卡，其中存储有账户余额，用户通过将用户终端贴近地铁闸机的感应区，以进站或出站，收款设备会 改写用户终端的安全芯片中存储的账户余额，以完成扣款。
而在本说明书实施例中，用户终端中并未存储账户余额，收款设备也并不会直接执行扣款操作，收款设备实际上是请求服务器从用户的账户中进行扣款。其中，用户的账户标识是用户在服务器上注册账户而获得的。因此，收款设备需要将用户终端发送的账户标识发送给服务器，以请求服务器从用户的账户中扣除乘车费，如此一来，收款设备就完成了收款。
此外，理论上用户A可以使用对用户B的账户标识进行加密得到的加密数据进站。也就是说，当用户B进站时，用户A可以截获用户B的用户终端传输给收款设备的加密数据，随后使用该加密数据进站，服务器也会对用户A的账户扣款。
为了防止这种情形发生，在步骤S202中，用户终端可以获取当前时间对应的时间戳，对用户的账户标识和所述时间戳进行加密，得到加密数据。在步骤S208中，收款设备对加密数据进行解密得到账户标识和时间戳，在步骤S210中，收款设备可以判断解密得到的时间戳到当前时间的时间间隔是否满足指定条件，若是，则将所述账户标识发送给服务器，否则，则拒绝将所述账户标识发送给服务器。所述指定条件可以是指定时长，可以根据需要指定，如5秒。
这样的话，用户B即便截获加密数据，随后使用加密数据进站，收款设备也会判断出该加密数据因超时而无效，收款设备可以拒绝将所述账户标识发送给服务器。
此外，虽然当加密数据是用户A的用户终端对账户标识和当前时间对应的时间戳加密得到的时，可以防止用户B截获加密数据随后进站，但是，用户B却可以使用截获的加密数据，在用户A进站的同一时间，于另一个地铁闸机处进站。
因此，进一步地，在步骤S202中，用户终端还可以获取所述收款设备的设备标识，对用户的账户标识、当前时间对应的时间戳和所述设备标识进行加密，得到加密数据。其中，用户终端可以通过建立的NFC连接获取 所述设备标识。在步骤S208中，收款设备对所述加密数据进行解密，得到所述账户标识、时间戳和所述设备标识。在步骤S210中，收款设备既需要判断解密得到的时间戳到当前时间的时间间隔是否满足指定条件，也需要判断解密得到的所述设备标识与自身的设备标识是否一致，若两个判断结果都为是，则将所述账户标识发送给服务器，若有一个判断结果为否，则拒绝将所述账户标识发送给服务器。
如此一来，用户B即便截获到用户A的加密数据，并在用户A进站的同时，于另一个地铁闸机处进站(或上另一辆公共汽车)，另一个地铁闸机也会判断出解密加密数据得到的设备标识并不是自身的设备标识，因而拒绝将所述账户标识发送给服务器。
当然，上述采用时间戳和采用设备标识的技术手段可以分开使用。也即，用户终端可以对账户标识和当前时间对应的时间戳进行加密得到加密数据，也可以对账户标识和收款设备的设备标识进行加密得到加密数据。
此外，在本说明书实施例中，当收款设备是在线状态时，收款设备将账户标识发送给服务器的同时，可以控制入口开启和/或者不报错，以允许用户进站或上车。收款设备拒绝将账户标识发送给服务器的同时，可以报错和/或控制入口关闭，以阻止用户进站或上车。
当收款设备是离线状态时，若收款设备拒绝将账户标识发送给服务器，则收款设备报错和/或控制入口关闭，以阻止用户进站或上车即可。若收款设备需要向服务发送账户标识，则收款设备可以先存储待发送的账户标识，同时控制入口开启和/或者不报错，以允许用户进站或上车。然后，收款设备可以待连接到网络时，再向服务器发送存储的账户标识。
通过图2所示的方法，用户终端无须具备安全芯片，这节省了硬件成本，同时，用户的账户余额由服务器进行记录和修改，用户依然可以通过“刷手机”的方式乘坐公共交通工具。哪怕用户的用户终端不具有安全芯片，用户也同样可以使用用户终端贴近地铁闸机来进站，体验“触碰支付”。

本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相 同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于图5和图6所示的设备而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字符***“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
上述实施例阐明的***、装置、模块或单元，具体可以由计算机芯片或实体实现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可以为个人计算机、膝上型计算机、蜂窝电话、相机电话、智能电话、个人数字符助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
为了描述的方便，描述以上装置时以功能分为各种单元分别描述。当然，在实施本说明书时可以把各单元的功能在同一个或多个软件和/或硬件中实现。
本领域内的技术人员应明白，本发明的实施例可提供为方法、***、或计算机程序产品。因此，本发明可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本发明可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的 形式。
本发明是参照根据本发明实施例的方法、设备(***)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
在一个典型的配置中，计算设备包括一个或多个处理器(CPU)、输入/输出接口、网络接口和内存。
内存可能包括计算机可读介质中的非永久性存储器，随机存取存储器(RAM)和/或非易失性内存等形式，如只读存储器(ROM)或闪存(flash RAM)。内存是计算机可读介质的示例。
计算机可读介质包括永久性和非永久性、可移动和非可移动媒体可以由任何方法或技术来实现信息存储。信息可以是计算机可读指令、数据结构、程序的模块或其他数据。计算机的存储介质的例子包括，但不限于相变内存(PRAM)、静态随机存取存储器(SRAM)、动态随机存取存储器 (DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、快闪记忆体或其他内存技术、只读光盘只读存储器(CD-ROM)、数字符多功能光盘(DVD)或其他光学存储、磁盒式磁带，磁带磁磁盘存储或其他磁性存储设备或任何其他非传输介质，可用于存储可以被计算设备访问的信息。按照本文中的界定，计算机可读介质不包括暂存电脑可读媒体(transitory media)，如调制的数据信号和载波。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
