本发明的实施方式
本发明实施例提供一种终端设备的数据存储方法，参照图1，在一实施 例中，所述终端设备的数据存储方法包括以下步骤：
步骤S101，获取终端设备的待存储数据；
本实施例中，终端设备可以为手机等移动终端。以手机为例，所述待存储数据可以是短信、通讯录、照片、备忘录等信息。
步骤S102，判断所述待存储数据是保密数据还是非保密数据；
本实施例中，终端设备根据待存储数据的属性判断是保密数据还是非保密数据。以手机为例，短信、通讯录、照片、备忘录、语音视频、QQ聊天记录以及微信聊天记录等均属于保密数据，其他则可以为非保密数据。在其他实施例中，可以根据实际需要选择其他保密数据，并不局限于本实施例。
步骤S103，若所述待存储数据是保密数据，则对所述待存储数据进行加密处理，并将经加密处理后的待存储数据存储于存储卡；
本实施例中，加密处理包括转义以及预设密码的处理方式，存储卡包括SIM卡(Subscriber Identity Module，客户识别模块卡)以及SD卡(SD卡Secure Digital Memory Card，安全数码卡)等，在其他实施例中，可以选择其他类型存储卡，并不局限于本实施例。
步骤S104，若所述待存储数据是非保密数据，则将所述待存储数据存储于所述存储卡。
本实施例中，终端设备对待存储数据进行判断，若所述待存储数据是非保密数据，则将待存储数据直接存储于存储卡如SIM卡即可。
本发明实施例提供的终端设备的数据存储方法，通过获取终端设备的待存储数据，判断所述待存储数据是保密数据还是非保密数据，若所述待存储数据是保密数据，则对所述待存储数据进行加密处理，并将经加密处理后的待存储数据存储于存储卡。这样，通过基于存储卡如SIM卡对终端设备的安全域和普通域的数据进行区分存储，不仅可以保证数据存储的安全性，还可以避免终端设备损坏时造成的存储数据丢失的现象。
在一实施例中，如图2所示，在图1的实施例的基础上，所述终端设备包括普通域和安全域，所述步骤S103包括：
步骤S1031，若所述待存储数据是保密数据，则将所述待存储数据放入安全域；
本实施例中，终端设备如手机，通常具备普通域和安全域两个系统，若手机是安卓操作系统、苹果操作系统或塞班操作系统等的一种，则在普通域内可以实现对应系统的常规操作；而在安全域，用户可将隐私信息放在安全域内，在此系统内仅提供电话、短信以及拍照等最基础的功能，并断开一切网络连接。当用户需要正常使用手机时，切换到对应的操作系统如安卓系统即可。可以理解的是，这两个系统采用硬件隔离方式，分别安装在两个存储空间，完全独立运行，无法互相访问。若待存储数据是短信、通讯录、照片、备忘录、语音视频、QQ聊天记录以及微信聊天记录等类型中的一种或多种，则将待存储数据放入安全域。
步骤S1032，提取安全域中所述待存储数据的头文件；
步骤S1033，对所述头文件进行转义处理，得到转义数据；
本实施例中，当待存储数据处于安全域时，提取所述待存储数据的头文件，头文件采用编码制度，对头文件进行整体编码，如采用Unicode(统一码、万国码、单一码)编码，头文件编码为A0 B2 00 00。
本实施例中，对所述头文件A0 B2 00 00进行字母字符映射或字符解析处理，得到转义数据，如下：
1、头文件采用字母字符映射模式，即字符与字母间的自定义映射，如数字0～9对应字母a～j，即头文件A0 B2 00 00采用字母字符映射后转义为Aa Bc aa aa。
2、头文件采用解析字符模式，即头文件采用字符转义，例如采用“/”转义字符，将头文件A0 B2 00 00转义为/A0 B2 00 00。
可以理解的是，在其他实施例中，也可以直接改变头文件，如头文件A0 B2 00 00转义后为B0 B2 00 00等，转义方法可以根据实际需要合理设置。
由于头文件经过转义处理，因此，普通域无法正确解析数据，因而不会在通讯录和短信模块等显示安全域的信息。
步骤S1034，将所述转义数据进行预加密处理，得到加密数据；
本实施例中，预加密方式可以为用户预先以字母和/或数字、语音、手势、指纹等方式输入至终端设备的密码。
步骤S1035，将所述加密数据存储于所述存储卡。
本实施例中，终端设备将经加密处理后的转义数据存储于SIM卡、SD卡或其他类型的存储卡内。
由于先对待存储数据进行转义和加密处理，然后才进行存储，这样，可以保证存储卡如SIM卡在更换到另外一台终端设备时，若不知道加密密码，则无法在安全域进行读取SIM卡信息。
在一实施例中，如图3所示，在图1的实施例的基础上，所述步骤S103之后还包括：
步骤S105，获取所述存储卡中的存储数据；
步骤S106，判断所述存储数据是处于普通域还是安全域；
本实施例中，终端设备获取存储卡如SIM卡中预存的存储数据，并判断存储数据处于终端设备如手机的普通域还是安全域。
步骤S107，若所述存储数据处于普通域，则不读取所述存储数据；
本实施例中，若终端设备判断存储数据处于普通域，由于存储数据经过转义和加密处理，转义和加密处理后的数据格式与正常的数据格式不相同，故普通域无法正确解析存储数据，因而不会读取存储数据，也即普通域不会显示手机的通讯录以及短信等信息。
步骤S108，若所述存储数据处于安全域，则对所述存储数据进行解密处理；
本实施例中，若终端设备判断存储数据处于安全域，则获取用户输入的解密密码，若密码错误则跳转到不读取存储数据；若用户输入的解密密码密码正确，则对解密后的存储数据进行转义，以转义为正常的头文件格式。
步骤S109，将经解密处理后的存储数据在终端设备上进行显示，以供用 户读取。
本实施例中，终端设备将经解密和转义处理后的存储数据在终端设备上进行显示，这样，当手机损坏或丢失时，仍可正常读取存储于存储卡如SIM卡上的短信以及通讯录等信息。
在一实施例中，如图4所示，在图3的实施例的基础上，所述步骤S108包括：
步骤S1081，若所述存储数据处于安全域，则接收解密密码；
步骤S1082，判断所述解密密码是否与预加密密码一致；
本实施例中，当终端设备判断存储数据处于安全域时，则会接收用户输入的解密密码。预加密方式可以为用户预先以字母和/或数字、语音、手势、指纹等方式输入至终端设备的密码。终端设备会判断用户输入的解密密码是否与预加密密码一致。
步骤S1083，若一致，则对经解密处理后的存储数据进行转义处理。
本实施例中，在终端设备判断解密密码与预加密密码一致时，则对经解密处理后的存储数据进行转义处理；在终端设备判断解密密码与预加密密码不一致时，则无法进行解密操作，也即存储数据无法转义成正确的短信以及通讯录等信息。这样，在解密时需要输入与预加密密码一致的解密密码，不仅可以保证在终端设备如手机损坏时，仍可在其他终端设备的安全域进行正常读取，还可保证存储的安全性。
