具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”和“第三”等是用于区别不同对象，而非用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或装置没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或装置固有的其它步骤或单元。
本发明实施例中的移动终端，是一种为用户提供语音和/或数据连通性的设备，其可以和车载终端建立无线数据连接，且具备指纹获取模组，可以采集用户指纹。该移动终端可以包括但不限于智能手机（如Android手机、iOS手机、Windows Phone手机等）、平板电脑、掌上电脑、笔记本电脑、移动互联网设备（Mobile Internet Devices，MID）或穿戴式设备等，上述移动终端仅是举例，而非穷举，包含但不限于上述移动终端。
本发明实施例中的车载终端，可以与移动终端建立无线数据连接，其可以与汽车上的中控集成设置，也可以独立设置，本发明实施例不作任何限定，在其存储器中可以预先存储用户的指纹信息和用户使用的移动终端的标识信息。其可以对汽车上的各个部位进行控制，如车门、大灯、雨刮器、空调、车窗和天窗等。
下面结合附图，对本发明实施例的内容进行描述。
请参照图1，为本发明开启车门的方法的第一实施例的流程示意图，在本实施例中，所述方法包括以下步骤：
S101，移动终端与车载终端协商信息的加密算法和解密算法。
可选地，所述加密算法和解密算法为非对称密钥。
当然，如果安全性要求较低或者移动终端或车载终端的处理器能力较弱，也可以采用对称密钥，本发明实施例不作任何限定。
其中，对称密钥加密也叫秘密/专用密钥加密（Secret Key Encryption,SKE），即发送和接收数据的双方必须使用相同的/对称的密钥对明文进行加密和解密运算。 非对称密钥加密也叫公开密钥加密（Public Key Encryption，PKE），是指每个人都有一对唯一对应的密钥：公开密钥和私有密钥，公钥对外公开，私钥由个人秘密保存；用其中一把密钥来加密，就只能用另一把密钥来解密。发送数据的一方用另一方的公钥对发送的信息进行加密，然后由接受者用自己的私钥进行解密。公开密钥加密技术解决了密钥的发布和管理问题，是目前商业密码的核心。使用公开密钥技术，进行数据通信的双方可以安全地确认对方身份和公开密钥，提供通信的可鉴别性。
可选地，所述加密算法和解密算法对应且同时动态变化。例如，可以协商多套对应的加解密算法，然后是每次使用时约定使用其中一套，移动终端可以通过发生算法标识信息来告知车载终端。这样动态变化的加解密算法可以进一步提升系统的安全性。
S102，获取用户指纹信息并采用协商的加密算法进行加密。
可选地，在对用户指纹信息进行加密时，需要检测到与车载终端建立了无线数据连接且已获取到用户指纹信息。避免移动终端每次获取到指纹信息后都用该加密算法进行加密。或者也可以在终端打开特定应用的特定界面如汽车控制应用的控制界面后，才对获取到的指纹信息进行加密。
S103，将加密后的用户指纹信息发送给所述车载终端。
其中，所述加密后的用户指纹信息用于在所述车载终端采用协商的解密算法对其解密后与预存的用户指纹信息匹配并在匹配成功后开启汽车车门。。
可选地，在发送信息之前，移动终端可以通过短距离无线通信方式与汽车控制终端建立无限数据连接。
该短距离无线通信方式因为会用来传输加密后的指纹信息，因此要求保密性好，不扩散。例如，可以为蓝牙，近场通信(Near Field Communication，NFC)，无线保真（Wireless-Fidelity，Wi-Fi）等。本发明实施例不作限定。
需要说明的是，由于一个家庭可能存在多个成员，因此可以在汽车的车载终端上预存多个用户的指纹信息，这样家庭成员中的所有用户都可以使用本实施例中的方法来开启车门。
可选地，当车载终端对指纹信息的匹配成功之后，可以直接控制汽车车门开启，或者，也可以暂时不开启，等待接收移动终端发送的控制指令再控制车门开启。
需要说明的是，在本实施例中，具体描述了开启车门的控制，这是进入汽车使用汽车的基本步骤，但是本发明实施例所述的方法除了可以应用在控制车门开启之外，同样还可以应用在汽车其他部件的控制上，例如，移动终端上可以安装一个控制汽车的应用，其中可以模拟汽车的各个部件或者使用多个按键对应汽车的各个部件，用户可以在指纹匹配成功之后，通过移动终端控制汽车的各个部件如大灯、空调、车窗、音响等，本发明实施例不做任何限定。
可选地，如果匹配失败，则不会开启车门，车载终端也不会执行移动终端发送的控制指令。
若连续预设次数匹配失败，则所述移动终端发送给所述车载终端的信息在预设时长内被拒收，或者所述移动终端与所述车载终端的连接在预设时长内被断开。
例如，车载终端可以在连续4次指纹匹配失败后，在一个小时内断开与该移动终端的无线数据连接，或者也可以不断开无线数据连接，但是在一个小时内拒绝接收该移动终端发送的信息。或者还可以在连续匹配失败后引入报警机制以提醒车主。从而提防不法份子持续套取指纹、试图非法开启车门的不良企图，提升系统的安全性。
下面举例说明本实施例中所述的方法可以运用的场景：
场景一、用户走到汽车旁边，移动终端自动与车载终端进行蓝牙连接，用户打开移动终端上车门控制应用进入车门开启界面，将手指放在指纹识别模块上，移动终端获取用户指纹，加密该指纹并通过该蓝牙连接发送给车载终端，车载终端对该指纹解密，并与预存的用户指纹匹配，匹配通过，汽车车门解锁。
场景二、偷窃者在汽车旁破解车载终端的无线连接，例如蓝牙连接，发送窃取的指纹信息到车载终端，车载终端对接收到的指纹信息解密，由于没有匹配的加密算法，因此解密后得到乱码，匹配失败，多次尝试失败后，汽车断开无线连接，并向车主发送通知。
在本实施例中，通过发送加密后的指纹信息而并不发送车门开启指令到车载终端，从而可以为系统提供双层防护，第一层由加密算法构成的解密防护，第二层是由指纹信息的唯一性和复杂性构成的复杂计算防护，使得偷窃者无法破解或模拟移动终端发送给车载终端的信号，在实现利用用户移动终端解锁车门，方便用户使用的同时，保证了用户汽车的安全。
需要说明的是，本发明实施例仅针对较常见的车门开启场景进行了详细描述，但是本实施例所述的方法除了应用于汽车车门开启之外，同样可以应用于其他车门开启的领域如智能门禁等，或者还可以应用于其他可以采用指纹加解密进行验证后进行控制的场景中。
请参照图2，为本发明开启车门的方法的第二实施例的流程示意图，在本实施例中，所述方法包括：

S202，获取用户指纹信息和所述移动终端的标识信息并采用协商的加密算法进行加密。
S203，将加密后的所述用户指纹信息和所述标识信息发送给所述车载终端。
所述加密后的标识信息用于在所述车载终端采用协商的解密算法对其解密后与预存的标识信息匹配并在用户指纹信息与标识信息均匹配成功后开启汽车车门。
在本发明实施例中，增加了移动终端的标识信息匹配的过程，通过对移动终端标识信息的加密和解密，可以进一步提升系统的安全性。且预存的标识信息中可以包含用户家庭或朋友的多个移动终端的标识信息，结合预存的多个指纹信息，可以实现多个可靠用户的移动终端对车门的开启。
请参照图3，为本发明开启车门的方法的第三实施例的流程示意图，在本实施例中，所述方法包括以下步骤：
S301，车载终端与移动终端协商信息的加密算法和解密算法。
可选地，所述加密算法和解密算法为非对称密钥。
当然，如果安全性要求较低或者移动终端或车载终端的处理器能力较弱，也可以采用对称密钥，本发明实施例不作任何限定。
其中，对称密钥加密也叫秘密/专用密钥加密（Secret Key Encryption,SKE），即发送和接收数据的双方必须使用相同的/对称的密钥对明文进行加密和解密运算。 非对称密钥加密也叫公开密钥加密（Public Key Encryption，PKE），是指每个人都有一对唯一对应的密钥：公开密钥和私有密钥，公钥对外公开，私钥由个人秘密保存；用其中一把密钥来加密，就只能用另一把密钥来解密。发送数据的一方用另一方的公钥对发送的信息进行加密，然后由接受者用自己的私钥进行解密。公开密钥加密技术解决了密钥的发布和管理问题，是目前商业密码的核心。使用公开密钥技术，进行数据通信的双方可以安全地确认对方身份和公开密钥，提供通信的可鉴别性。
可选地，所述加密算法和解密算法对应且同时动态变化。例如，可以协商多套对应的加解密算法，然后是每次使用时约定使用其中一套，移动终端可以通过发生算法标识信息来告知车载终端。这样动态变化的加解密算法可以进一步提升系统的安全性。
S302，接收所述移动终端发送的加密后的信息。
S303，采用协商的解密算法对接收到的信息进行解密并与预存的信息进行匹配。
