具体实施方式
实施例1
本实施例提供了一种基于物联网打车的方法。图1是一种基于物联网打车的方法的流程图。该方法可以应用于用户终端，该用户终端可以为具有安全芯片、物联网通信功能、无载波通信(Ultra Wideband，缩写为UWB)功能、近距离无线通信(Near Field Communication，缩写为NFC)功能以及蓝牙通信功能的装置，该用户终端可以为智能手机、智能可穿戴设备等设备。本实施例对此并不做出限制。如图1所示，该方法包括以下步骤(S101-S104)：
S101、从电子标签获取防窜改标签信息，其中，防窜改标签信息包括：采用电子标签的私钥对标签所在位置明文信息签名生成的签名数据以及标签所在位置明文信息，或者，采用预设密钥对标签所在位置明文信息加密生成的密文信息；
本实施例中，乘客用户在用户终端上登录打车平台客户端，登录到打车平台客户端上的账号都具有唯一的用户ID，下文中所提到的用户ID即乘客用户的登录账号对应的用户ID。
乘客用户在登录打车平台客户端后，用户终端从电子标签获取防窜改标签信息。本实施例中，电子标签可以为以下之一：NFC标签、蓝牙标签和UWB标签。当电子标签为NFC标签时，用户终端与电子标签建立NFC通信；当电子标签为蓝牙标签时，用户终端与电子标签建立蓝牙通信；当电子标签为UWB标签时，用户终端与电子标签建立UWB通信。其中，当电子标签为NFC标签或蓝牙标签时，电子标签通过GPS或北斗导航完成自身的定位，进而获取标签所在位置明文信息；当电子标签为UWB标签时，UWB标签通过与UWB基 站进行通信，完成自身的精确定位，进而获取实时的标签所在位置明文信息。其中，标签所在位置明文信息包括经纬度和地理位置信息。
为了防止电子标签的标签信息被篡改，本实施例中，电子标签采用电子标签的私钥对标签所在位置明文信息签名生成的签名数据以及标签所在位置明文信息，或者，采用预设密钥对标签所在位置明文信息加密生成的密文信息，由此可以确保没有权限获取电子标签的公钥或者预设密钥的第三方设备是无法获得标签所在位置明文信息的，也就是说，如果第三方设备在获取到防窜改标签信息后，如果没有电子标签的公钥，则无法对签名数据验签名，或者对签名数据验签名不通过，则不能获取标签所在位置明文信息；或者，如果第三方设备在获取到防窜改标签信息后，没有对应的密钥对密文信息进行解密，也不能获取标签所在位置明文信息。由此，保证电子标签的标签信息不能未授权的第三方获取，也不能轻易被篡改。
作为本实施例中一种可选的实施方式，从电子标签获取防窜改标签信息，包括以下方式之一：通过近距离无线通信NFC、蓝牙通信或无载波通信UWB的方式读取电子标签中的防窜改标签信息；扫描电子标签外部显示的二维码获取防窜改标签信息，二维码包含防窜改标签信息；通过内置在用户终端中的电子标签，生成防窜改标签信息。对于前述两种方式，电子标签可以作为地标标签布放在任何允许布放的位置上，例如将电子标签粘贴到公交车站、打车点、小区大门等便于停车打车的位置。用户终端可以通过NFC、蓝牙或者UWB方式与电子标签进行通信，获取电子标签中存储的防窜改标签信息，或者，用户终端可以扫描电子标签外部显示的包含有防窜改标签信息的二维码，进而获取防窜改标签信息。对于前述最后一种方式，电子标签内置在用户终端内部，用户终端通过内置的移动模组生成实时的位置标签，并进行加密或签名处理获得防窜改标签信息。由此，上述3种方式都可以使用户获取电子标签提供的定位，特别是UWB标签提供的精准定位，能够帮助用户精确定位打车的起始位置，无需用户再手动调整，提高了打车效率以及用户体验。特别是在后一种方式中，由于用户一般随身携带用户终端，用户走到哪儿，UWB标签就可以实时地精准定位该用户所在的位置，进而能够实时地获取用户位置。
S102、对防窜改标签信息进行处理获取标签所在位置明文信息作为行程起始位置，并根据防窜改标签信息生成打车订单信息，其中，打车订单信息包括：用户ID、行程起始位置和发起时间，且打车订单信息不包括行程目的位置；
其中，用户ID唯一标识该打车用户，一个用户在同一时间只能生成一个打车订单信息，以保证预约打车的是用户本人。而且，保证打车平台仅为该用户分配一辆预约车，保证资 源利用率最优。
此外，本实施例中，发起时间为生成打车订单信息的时间，可以唯一标识该订单。此外，打车订单信息中不包含行程目的位置，无需用户提供目的地位置信息，使得用户可以随时修改目的地，用户体验良好，且可以隐藏用户隐私信息，保障用户行程安全。
本实施例中，用户终端内置有安全芯片，可以对数据进行加解密处理以及签名验签处理，且安全芯片中可以预先存储预设密钥及电子标签的公钥，电子标签的公钥不能被读出，能够保证电子标签的公钥的保密性及安全性。作为本实施例中一种可选的实施方式，用户终端对防窜改标签信息进行处理获取标签所在位置明文信息作为行程起始位置，并根据防窜改标签信息生成打车订单信息，包括：
在防窜改标签信息包括采用电子标签的私钥对标签所在位置明文信息签名生成的签名数据以及标签所在位置明文信息的情况下，用户终端利用电子标签的公钥对签名数据进行验签名，且验证通过后将标签所在位置明文信息作为行程起始位置，并根据防窜改标签信息生成打车订单信息；
在防窜改标签信息包括采用预设密钥对标签所在位置明文信息加密生成的密文信息的情况下，用户终端利用预设密钥对密文信息进行解密得到标签所在位置明文信息，将标签所在位置明文信息作为行程起始位置，并根据防窜改标签信息生成打车订单信息。
本实施例中，预设密钥可以为用户终端与电子标签预先协商的密钥。用户终端在获取防窜改标签信息后，只有对签名数据验签通过，或者能够对采用预设密钥对标签所在位置明文信息加密生成的密文信息进行解密的情况下，才能够获取到标签所在位置明文信息，才能生存打车订单信息，一方面可以保证标签所在位置明文信息传输的安全性，另一方面可以防止标签所在位置明文信息被篡改，确保生成的打车订单信息的真实性和安全性。
S103、通过物联网将打车预约请求发送至打车平台，打车预约请求包括：打车订单信息；
S104、通过打车平台将打车订单信息发送至打车平台根据预设规则安排的预约车，并通过物联网接收打车平台返回的打车预约成功响应，打车预约成功响应包括：预约车的车辆信息以及预计到达时间。
本实施例中，用户终端通过物联网与打车平台通信。打车平台在接收到用户终端发送的打车预约请求后，根据预设规则选择位置最优的预约车安排给该用户，并向安排的预约车发送派单指令，其中，派单指令中包括：打车订单信息和预约车的车辆信息；预约车在接收到派单指令后，向打车平台返回同意接单响应，并将打车订单信息中的标签所在位置 信息作为目的地，打车平台在接收到预约车返回的同意接单响应后，通过物联网向用户终端发送打车预约成功响应，其中，打车预约成功响应包括：预约车的车辆信息以及预计到达时间。
本实施例中，预约车在到达目的地后向打车平台发送车辆到达指定位置信息，作为本实施例中一种可选的实施方式，本实施例提供的方法还包括：通过物联网接收打车平台返回的预约车到达标签所在位置信息后的车辆到达提醒信息，车辆到达提醒信息包括：预约车的车辆信息，以及时提醒用户乘车。
作为本实施例中一种可选的实施方式，本实施例提供的方法还包括：用户终端与打车平台之间建立数据安全传输通道，并通过数据安全传输通道传输数据。
具体地，为了保证用户终端与打车平台之间数据传输的安全性，用户终端与打车平台之间可以通过建立安全通道进行数据传输的方式传输打车预约请求、打车预约成功响应以及车辆到达提醒信息等信息。例如，用户终端与打车平台之间协商出会话密钥，在传输上述信息过程中，利用会话密钥对上述信息进行加密后传输，或者用户终端与打车平台之间预存多组会话密钥，二者选择特定的会话密钥加密上述信息。由此可以保证用户终端与打车平台之间数据传输的安全性。
本实施例提供的基于物联网打车的方法，通过电子标签获取标签所在位置明文信息，特别是当电子标签为UWB标签时，能够帮助用户精确定位打车的起始位置，且无需用户提供目的地位置信息，使得用户可以随时修改目的地，用户体验良好，且可以隐藏用户隐私信息，保障用户行程安全。
