其中，具体地，本实施例中，所述计算机程序被处理器执行时实现的步骤如下：
S1：捕获一第一操作指令，启动安全模式
优选地，当所述的移动终端为搭载安卓(Android)系统的移动终端时，所述的安全模式为：Recovery模式，是Android移动终端备份功能，指的是一种可以对安卓机内部的数据或系统进行修改的模式(类似于windows PE或DOS)。在这个模式下用户可以对已有的系统进行备份或升级，也可以在此恢复出厂设置。recovery的使用原理就和电脑上的GHOST软件一样，起到系统备份与还原作用。当然也可以升级内核，刷补丁等。recovery的编写是和系统基带联系在一起的，不同的基带版本不能乱刷。进入recovery界面，用户可以直接用sd卡上的zip格式的rom升(降)级(备份)用户的系统。
从而，本实施例中，当用户触发移动终端，并向所述移动终端发送一操作指令后，所述移动终端根据所述操作指令，进入所述移动终端的安全模式。
其中，优选地，参阅图2，其为一符合本发明一优选地捕获一第一操作指令，启动安全模式的步骤的流程示意图。从图中可以看出，本实施例中，所提供的捕获一第一操作指令，启动安全模式的步骤包括：
-捕获一对移动终端输入的操作指令
-解析所述操作指令，获得一操作内容
-根据所述操作内容，控制所述移动终端进入安全模式
可见，本实施例中，用户可以通过按动所述移动终端上的特定功能键的形式，向所述移动终端输入一操作指令；所述移动终端感应到所述操作指令后，进一步解析所述操作指令，如，获取用户的按键位置，按键力度等，并根据解析后的操作指令获得所述操作指令指向的操作内容，从而，进一步控制所述移动终端进入安全模式。
其中，更加优选地，本实施例中，进入recovery的方法：
1、将移动终端完全关机后，按住音量键下(上)+电源键，进入bootloader界面；
2、按音量键将光标移动到recovery那一行；
3、按电源键，之后移动终端会自动重启进入recovery模式。
其中，音量键为光标选择键，可以用来移动光标，电源键则是确认键。
S2：在所述安全模式下，选择并进入恢复出厂设置保护程序
优选地，当所述的移动终端为搭载安卓(Android)系统的移动终端时，恢复出厂设置保护(FRP，Factory Reset Protection)，为谷歌开发的安卓设备中的一种保护措施，可 以在设备被盗、丢失后保护设备，防止未经授权的用户登录或使用。
为防止用户信息在移动终端丢失后外泄，Google要求Android 5.1版本及以后版本都需要具备FRP功能且默认开启。此安全特性可以防止未经授权的用户登陆或使用设备。例如，若移动终端丢失或被盗，只要FRP功能处于使能状态，用户可以通过远程登陆Google账户的方式进行清除用户数据的操作，避免信息外泄，且经过此方法进行恢复出厂后需要在开机导航验证最近一次登陆过的Google账户才可进入系统，并正常使用移动终端。用户可以通过“设置-开发者选项-开启OEM解锁”菜单控制FRP功能的开启和关闭，OEM开关处于关闭状态，代表FRP功能为开启状态。FRP开启时，Secureboot不能解锁，fastboot刷机命令不能执行。
现有技术中，FRP基本功能的使用方法及步骤包括：FRP使用＝支持FRP+开启FRP+存在Google账号，其步骤为：a.进入设置->开发者选项->OEM解锁，关闭“OEM解锁”开关(开启FRP)；b.测试机连接VPN，登陆Google账户(存在Google账号)；c.设置锁屏密码。可见，现有技术中，用户只有在具有且知道Google账户及其密码的情况下才可实现对FRP中的数据进行处理。
继续参阅图1，本实施例中，用户可以实现在安全模式下，通过触发所述移动终端上特定按钮的形式，向所述移动终端发送一操作指令，所述移动终端解析所述操作指令后，可以按照所述操作指令，进入所述移动终端的恢复出厂设置保护程序。从而，实现不用登陆Google账户的情况下，实现正常使用恢复出厂设置保护程序。
S3：在恢复出厂设置保护程序中，选择擦除恢复出厂设置保护数据
继续参阅图1，本实施例中，用户可以实现在恢复出厂设置保护程序下，通过触发所述移动终端上特定按钮的形式，向所述移动终端发送一操作指令，所述移动终端解析所述操作指令后，可以按照所述操作指令，选择擦除恢复出厂设置保护数据。
S4：捕获一第二操作指令，输入一密码信息
继续参阅图1，本实施例中，所述移动终端感应用户选择擦除恢复出厂设置保护数据后，将，如通过在所述移动终端的显示屏幕中弹出一对话框的形式，发出一密码请求。用户借助所述移动终端的键盘等，向所述移动终端输入一密码信息，也即发送一第二操作指令；所述移动终端读取用户输入的密码信息后，将所述密码信息转换为一计算机可读的数字信息，如将十进制的数字转换为二进制数字信息等，并向外发送。
具体地，所述密码信息为所述恢复出厂设置保护程序的解锁码。
更加优选地，参阅图3，其为一符合图1中一优选地获取恢复出厂设置保护程序的解锁码的步骤的流程示意图。从图中可以看出，本实施例中，所述解锁码的获取方法包括：
-读取移动终端的国际移动设备身份码
本实施例中，国际移动设备身份码(IMEI，International Mobile Equipment Identity)是国际移动设备身份码的缩写，国际移动装备辨识码，是由15位数字组成的"电子串号"，它与每台手机一一对应，而且该码是全世界唯一的。每一只手机在组装完成后都将被赋予一个全球唯一的一组号码，这个号码从生产到交付使用都将被制造生产的厂商所记录。
IMEI为TAC+FAC+SNR+SP，其组成为:
1、前6位数(TAC)是"型号核准号码"，一般代表机型。
2、接着的2位数(FAC)是"最后装配号"，一般代表产地。
3、之后的6位数(SNR)是"串号"，一般代表生产顺序号。
4、最后1位数(SP)通常是"0"，为检验码，目前暂备用。
IMEI码贴在移动电话机背面的标志上(也存储于手机内，可通过在移动电话机上按“*#06#”获得)，并且读写于移动电话机内存中。它也是该移动电话机在厂家的"档案"和"身份证号"。
从而，本实施例中，可以通过读取移动终端上的标识信息或者通过移动终端上按“*#06#”获得所述移动终端的国际移动设备身份码。
-根据所述国际移动设备身份码检索所述移动终端的恢复出厂设置保护程序的解锁码
继续参阅图3，本实施例中，可以借助FRP解锁工具，如ComPartner平台，的“查询解锁码”功能中用IMEI查询到FRP解锁码。
S5：将所述密码信息与一预设密码进行比较
继续参阅图1，本实施中，当所述移动终端捕获一用户对所述移动终端输入的一密码信息后，所述移动终端将进一步将所述密码信息与所述移动终端中预先存储的一预设密码相比对。
S6：当所述密码信息与所述预设密码相匹配时，擦除恢复出厂设置保护数据
继续参阅图1，本实施例中，当所述移动终端比较结果为所述密码信息与所述预设密码相匹配时，所述移动终端可以获得权限擦除恢复出厂设置保护数据。从而，实现绕过谷歌账号密码，一键擦除FRP分区数据的技术效果。
优选地，参阅图4，其为一符合图1中一优选地将恢复出厂设置保护程序的入口写入安全模式的步骤的流程示意图。从图中可以看出，本实施例中，所提出的将恢复出厂设置保护程序的入口写入安全模式的步骤包括：
-启动安全模式的设置权限；
-将恢复出厂设置保护程序的入口写入安全模式中。
具体地，还是在linux环境下改写recovery.img，下载split_bootimg.zip文件，在此zip文件中包含一个perl文件，split_bootimg.pl脚本，该脚本可以读取recovery.img，将kernel和ramdisk读取出来，此脚本也会输出内核命令行和板子名字。解包recovery.img；使用mkbootfs工具来重新创建ramdisk；使用mkbootimg来重新创建recovery-new.img，得到了一个新的recovery-new.img，然后刷入第三方recovery的方法刷入即可。
其中，优选地，本实施例中，可重新制作一满足条件的recovery，并写入原recovery中，具体步骤如下：
1.从官方包，解压出原生的recovery.img；
2.解出原生recovery包的内核recovery.img-kernel和ramdisk内存镜像，再把ramdisk内存镜像解包；
3.找到合适的功能比较好的第三方recovery包，比如以G6的recovery-clockwork-5.0.2.0.img为例，同样解出其内核kernel和ramdisk内存镜像，再把ramdisk内存镜像解包；
4.准备新recovery的内核，本实施例中，使用官方原生包的recovery.img-kernel，只有原生的内核才能跟移动终端的硬件匹配；
5.修改ramdisk内存盘，
6.按照上面打包ramdisk的方法打包新改的ramdisk内存盘；
7.按照上面打包img的方法打包生成新的recovery-new.img；
8.将新的recovery-new.img刷入手机；
9.打开手机原生的recovery.img，对比来两个文件的文件头，把原生的前16行(000h-100h)复制到新的recovery上覆盖。
10.最后把新的recovery-new.img，第二行的前三个字节改回到刚才记下的三个值，保存。
其中recovery.img-kernel为新内核；ramdisk-new.gz为新的内存盘；boot-new.img为生成的新img.按照此方法打包的boot.img或recovery.img因为基址和内核参数都正确可以直接移动终端上使用。
综上所述，本发明中，提供一种移动终端及用于数据擦除的计算机可读存储介质。本发明将FRP的入口写入recovery模式中，用户可以在recovery模式中，通过输入正确的FRP密码，实现擦除FRP分区中的个人信息数据。
