Abstract
一种智能终端系统启动方法、装置及智能终端，设置有两个访问密码分别是访客密码和机主密码，用户输入不同的密码，智能终端系统将挂载不同的用户数据分区，该用户数据分区包括机主数据分区和访客数据分区。如果用户输入的访问密码是访客密码，智能终端系统将挂载访客数据分区；智能终端系统挂载访客数据分区后，就像进行了恢复出厂设置一样，仅有系统自带的应用程序，且没有用户通过机主密码使用智能终端时所存储的数据；即，访客看不到机主自行安装的应用程序，而且看不到机主使用智能终端的系统应用时所存储的任何数据，因此，采用该方法能够更全面地保护机主的隐私信息。
Description
本发明涉及计算机技术领域，尤其是涉及智能终端系统启动方法、装置及智能终端。
随着智能终端(例如，智能手机、平板电脑)上能够安装的应用程序的数量不断增加，例如，支付宝、微信、手机银行等涉及个人隐私的应用程序，用户的隐私内容也越来越多。如果用户的智能终端被其它用户使用，智能终端内涉及用户隐私的内容将被其它用户看到，无法保证用户隐私内容的安全。
现有的一种保护用户隐私数据的方式是设置访客模式，特定信息作为隐私信息。在访客模式下无法访问特定信息(例如，短信、图片、视频、通讯录等)，从而保护用户隐私信息。
但是，目前的访客模式只能保护特定信息，无法保护用户安装的应用程序内的个人信息，即在访客模式下，访客可以看到用户安装了哪些应用程序，而且，能够看到用户的这些应用程序中的个人信息，因此，访客模式对用户的个人隐私信息的保护力度很小，无法满足用户的需求。

数据；即，访客看不到机主自行安装的应用程序，而且看不到机主使用智能终端的系统应用时所存储的任何数据，因此，采用该方法能够更全面地保护机主的隐私信息。
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

图7示出了本发明实施例示出的一种智能终端的结构示意图。
为了使本领域技术人员更好地理解本发明方案，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，所述描述的实施例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做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。
请参见图1，示出了本发明实施例一种智能终端系统启动方法的流程图，该方法应用于智能终端中，例如，智能终端可以是智能手机、平板电脑、PDA(Personal Digital Assistant，个人数字助理)、POS(Point of Sales，销售终端)、或车载电脑等。
本发明实施例中，智能终端设置有两个访问密码分别是机主密码和访客密码，而且，在智能终端的非易失性存储区域内划分一个特定的区域存储访问密码与用户数据分区之间的映射关系，具体的，保存机主密码与机主数据分区之间的映射关系，以及访客密码和访客数据分区之间的映射关系。
其中，智能终端的系统程序存储在系统数据分区内，且该系统数据分区是只读存储区，用户在正常情况下无法修改系统数据分区内的数据，例如，无法删除系统自带的应用程序。用户通过机主密码使用智能终端时所产生的数据存储在机主数据分区；通过机主密码使用智能终端的用户统称为机主，并非仅指智能终端的拥有者。例如，
机主安装的应用程序存储在机主数据分区中；又如，用户使用应用程序所产生的数据，例如，通话记录、通讯录、社交软件聊天记录等。访客数据分区是智能终端内除系统数据分区和机主数据分区之外的存储区域。
如图1所示，所述方法可以包括以下步骤：
S110，在智能终端处于系统启动过程中或锁屏状态时，智能终端检测用户是否输入访问密码；如果检测到用户输入的访问密码，则执行S120；如果没有检测到用户输入的访问密码，则结束当前流程。
在本发明一个应用场景中，智能终端在启动时，就提示用户输入访问密码，智能终端检测用户输入的访问密码。
在本发明另一个应用场景中，智能终端已经完全启动，处于锁屏状态，而且需要输入访问密码才能解锁进而访问智能终端。
S120，智能终端判断所述访问密码是否与访客密码或机主密码相匹配；如果访问密码与访客密码相匹配，则执行S130；如果访问密码与机主密码相匹配，则执行S140；如果访问密码与机主密码和访客密码均不匹配，则结束当前流程。
在智能终端启动时，从非易失性存储区域内读取预先存储的访客密码和机主密码，比较用户输入的访问密码是否与访客密码或机主密码相同。
例如，智能终端检测到用户输入的访问密码后，可以首先判断该访问密码是否与机主密码相同；当访问密码与机主密码不相同时，继续判断该访问密码是否与访客密码相同；如果该访问密码与访客密码相同，则判断出访问密码是访客密码；如果该访问密码与访客密码不相同，则判断出访问密码不正确，结束当前流程。当然，判断
S130，智能终端系统挂载访客数据分区。
智能终端查询访问密码与用户数据分区之间的映射关系，得到与所述访客密码对应的访客数据分区。
所述访客数据分区是智能终端内除系统数据分区和机主数据分区之外的存储区域；所述系统数据分区用于存储智能终端的操作系统自带的系统程序；所述机主数据分区用于存储用户通过所述机主密码使用智能终端时所存储的信息。
智能终端挂载访客数据分区，是指智能终端系统加载访客数据分区，进而使智能终端系统能够对访客数据分区进行读/写操作。
智能终端的操作系统挂载访客数据分区后，就像进行了恢复出厂设置一样，仅有系统自带的应用程序，完全看不到机主自行安装的应用程序，也看不到机主在使用智能终端时所存储的数据，例如，通话记录、通讯录等。应当理解的是，智能终端根据
访客密码或机主密码挂载的是同一个操作系统的不同的数据分区，而不是不同的操作系统，与一些智能终端存在的双系统不同。
S140，智能终端系统挂载所述机主数据分区。
智能终端查询访问密码与用户数据分区之间的映射关系，得到与所述机主密码对应的机主数据分区。
智能终端系统挂载机主数据分区，挂载机主数据分区后机主能够正常使用智能终端，能够看到机主安装的全部应用程序，以及能够看到机主使用智能手机时所产生的数据。
本实施例提供的智能终端系统启动方法，设置有两个访问密码分别是访客密码和机主密码，用户输入不同的密码，智能终端系统将挂载不同的用户数据分区，该用户数据分区包括机主数据分区和访客数据分区。具体的，如果用户输入的访问密码是访客密码，智能终端系统将挂载访客数据分区；如果访问密码是机主密码，则智能终端系统挂载机主数据分区。其中，访客数据分区是智能终端内除系统数据分区和机主数据分区之外的存储区域。系统数据分区用于存储智能终端系统自带的系统程序；机主数据分区用于存储用户通过机主密码使用智能终端时所存储的信息，该信息包括用户安装的应用程序及用户使用智能终端过程中所产生的数据。智能终端系统挂载访客数据分区后，就像进行了恢复出厂设置一样，仅有系统自带的应用程序，且没有用户通过机主密码使用智能终端时所存储的数据；即，访客看不到机主自行安装的应用程序，而且看不到机主使用智能终端的系统应用时所存储的任何数据，因此，采用该方法能够更全面地保护机主的隐私信息。
请参见图2，示出了本发明实施例另一种智能终端系统启动方法的流程图，本实施例用于智能终端开机启动的应用场景中。该实施例中的智能终端以手机为例进行描述，如图2所示，该方法包括以下步骤：
S210，手机检测到开机操作指令时，挂载系统数据分区。
手机在关机状态下检测到开机操作指令后，首先挂载系统数据分区(即，操作系统所在的数据分区)，即启动系统自带的应用程序；其中，开机操作指令由手机侦听到用户的开机或重启操作事件后产生。
S220，手机向用户展示访问密码输入界面，并获取用户在所述访问密码输入界面输入的访问密码。
手机挂载系统数据分区后，展示输入访问密码的界面，提示用户输入访问密码；并获取用户在访问密码输入界面输入的访问密码。
提示用户输入访问密码的方式可以是直接在手机的显示屏上显示输入访问密码的界面。手机按照指定的时间间隔侦听用户在该界面的输入事件，并获取用户输入的访问密码。
S230，手机判断所述访问密码是否是机主密码或访客密码；如果访问密码是访客密码，则执行S240；如果访问密码是机主密码则执行S260；如果访问密码与机主密码和访客密码均不相同，则结束当前流程。
手机预先在非易失性存储器内的特定区域内存储机主密码及该机主密码与机主数据分区之间的映射关系；以及，存储访客密码及该访客密码与访客数据分区之间的映射关系。访问密码与用户数据分区之间的映射关系具体是：访客密码对应访客数据分区；机主密码对应机主数据分区。
如果访问密码是数字密码，则在手机的非易失性存储器(例如，闪存)中存储该密码的具体数字，依次类推，对于图形密码，则存储具体图形，如果是指纹密码，则存储具体的指纹。
手机获得用户输入的访问密码后，比较该访问密码与预先存储的机主密码或访客密码是否相同。
S240，手机查询预先存储的访问密码与用户数据分区之间的映射关系，得到与所述访客密码相对应的访客数据分区。
S250，手机挂载所述访客数据分区。
手机挂载访客数据分区后，仅有系统自带的应用程序，完全看不到机主自行安装的应用程序，也看不到机主在使用智能终端时所存储的数据，例如，通话记录、通讯录等。
在本发明一个实施例中，手机预先在非易失性存储器中划分一块区域，即为访客预留的访客数据分区，可以保存访客使用手机时产生的数据。
在本发明另一个实施例中，在RAM(Random Access Memory，随机存取存储器)中通过挂载tmpfs作为所述访客数据分区。其中，tmpfs是一种基于内存的文件系统，tmpfs可以使用RAM或swap分区来存储文件，tmpfs主要存储暂存的文件。即在RAM中为访客临时划分一个存储区域，用来存储访客数据。
S260，手机查询预先存储的访问密码与用户数据分区之间的映射关系，得到与所述机主密码相对应的机主数据分区。
S270，手机挂载所述机主数据分区。
智能终端系统挂载机主数据分区，即机主能够正常使用智能终端，能够看到机主
安装的全部应用程序，以及能够看到机主使用智能手机时所产生的数据。
本实施例提供的智能终端系统启动方法，在智能终端启动过程中，启动完系统自带的应用程序后，向用户展示访问密码输入界面，并获取用户在该界面输入的访问密码。查询访问密码与用户数据分区之间的对应关系，得到用户输入的访问密码所对应的用户数据分区，并挂载该用户数据分区。具体的，用户输入访客密码，则挂载与访客密码相对应的访客数据分区；用户输入机主密码，则挂载与机主密码相对应的机主数据分区。智能终端系统挂载访客数据分区后，仅有系统自带的应用程序，访客看不到机主自行安装的应用程序，而且看不到机主使用智能终端的系统应用时所存储的任何数据，因此，采用该方法能够更全面地保护机主的隐私信息。
请参见图3，示出了本发明实施例另一种智能终端系统启动方法的流程图，本实施例应用于智能终端启动后处于锁屏状态时，切换不同的数据分区的应用场景中。本实施例仍以手机为例进行描述，如图3所示，该方法可以包括以下步骤：
S310，手机处于锁屏状态下，获取用户输入的访问密码。
S320，手机判断所述访问密码是否与机主密码或访客密码相匹配；如果访问密码与访客密码相匹配，则执行S330；如果访问密码与机主密码相匹配，则执行S370。如果访问密码既不是机主密码又不是访客密码，则结束当前流程。
S330，手机查询访问密码与用户数据分区之间的映射关系，得到与所述访客密码相对应的访客数据分区。
S340，手机判断当前挂载用户分区是否是所述访客数据分区，如果当前挂载用户分区不是访客数据分区，则执行S350；如果当前挂载用户分区是访客数据分区，则执行S360。
S350，手机卸载所述当前挂载用户分区，并挂载所述访客数据分区。
卸载数据分区，即手机系统移除已经加载的数据分区，即手机不能对卸载后的数据分区进行读/写操作。
手机停止当前运行的系统服务，卸载当前已经挂载的机主数据分区，然后挂载访客数据分区，并重启系统服务。
S360，手机保持当前挂载的访客数据分区不变。
S370，手机查询访问密码与用户数据分区之间的映射关系，得到与所述机主密码相对应的机主数据分区。
S380，手机判断当前挂载用户分区是否是所述机主数据分区，如果当前挂载用户分区不是机主数据分区，则执行步骤S390；如果当前挂载用户分区是机主数据分区，
则执行S3100。
S390，手机卸载所述当前挂载用户分区，并挂载所述机主数据分区。
手机停止当前运行的系统服务，卸载当前挂载的访客数据分区，然后挂载机主数据分区，并重启系统服务。
S3100，手机保持当前挂载的机主数据分区不变。
本实施例提供的智能终端系统启动方法，在智能终端启动后处于锁屏状态时，获得用户输入的访问密码后，判断访问密码的类型；如果访问密码是访客密码，则继续判断智能终端当前挂载的用户数据分区的类型；如果当前挂载用户分区是机主数据分区，则卸载所述机主数据分区并挂载与访客密码对应的访客数据分区。如果当前挂载用户分区是访客数据分区，则保持当前挂载的用户数据分区不变。如果访问密码是机主密码，则继续判断智能终端当前挂载的用户数据分区的类型；如果当前挂载用户分区是访客数据分区，则卸载所述访客数据分区，并挂载机主数据分区，从而实现智能终端上层应用重启，切换到用户输入的访问密码所对应的用户数据分区，操作更方便，不需要智能终端整机重启，仅是上层应用重新启动，启动速度快。
请参见图4，示出了本发明实施例另一种智能终端系统启动方法流程图，智能终端可以保存访客使用该智能终端所产生的访客数据。
该方法在图1-3任一实施例的基础上还可以包括以下步骤，本实施例在图1所示实施例的基础上增加以下步骤：
S410，当所述智能终端卸载所述访客数据分区时，向用户展示是否保存访客数据；所述访客数据是用户通过所述访客密码使用所述智能终端所产生的数据。
例如，智能终端当前挂载的是访客数据分区，当智能终端关机时智能终端会卸载访客数据分区；又如，智能终端挂载的用户数据分区由访客数据分区切换到机主数据分区时，智能终端也需要卸载访客数据分区。
S420，当检测到确认保存指令后，将所述访客数据存储到第一类存储区域中。所述确认保存指令由所述智能终端检测到用户的确认保存所述访客数据的操作后产生。
在本发明一个应用场景中，智能终端在非易失性存储器中为访客划分了访客数据分区，在此种应用场景下，第一类存储区域包括所述访客数据分区、所述智能终端的外置存储设备和云服务器中至少一个。
例如，访客数据可以存储到访客数据分区中；或者，访客数据存储到外置存储设备中；或者，访客数据存储到访客数据分区，同时同步到云服务器中；或者，访客数据存储到外置存储设备，同时同步到云服务器中。访客数据存储到云服务器中后，用
户可以将访客数据同步到其它智能终端中。
在本发明另一个应用场景中，智能终端在RAM上挂载tmpfs作为访客数据分区，即在RAM上为访客划分一个临时存储分区用来存储访客数据。在此种应用场景下，所述第一类存储区域包括所述外置存储设备和云服务器中的至少一个。RAM掉电会丢失数据，因此，RAM上不能存储访客数据。
本实施例提供的智能终端系统启动方法，当智能终端卸载访客数据分区时，智能终端会提示是否保存访客数据，如果用户确认需要保存访客数据，可以将访客数据存储到为访客预留的访客数据分区、外置存储设备和云服务器中的至少一种，从而使得访客下次使用该智能终端时，能够方便得看到自己使用该智能终端时所存储的数据，使访客使用更方便。
相应于上述的智能终端系统启动方法实施例，本发明还提供了智能终端系统启动装置实施例。
请参见图5，示出了本发明实施例一种智能终端系统启动装置的框图，如图5所示，该装置可以包括检测模块110、判断模块120、第一分区挂载模块130、第二分区挂载模块140。
检测模块110，用于当智能终端处于系统启动过程中或锁屏状态时，检测用户是否输入访问密码。
在本发明的一个应用场景下，智能终端由关机状态启动，当智能终端检测到开机操作指令时，挂载系统数据分区；然后，向用户展示访问密码输入界面，用户可以在访问密码输入界面输入访问密码。检测模块110检测用户是否在访问密码输入界面输入访问密码。
判断模块120，用于当检测模块110检测到用户输入访问密码时，判断所述访问密码是否与访客密码或机主密码相匹配。
所述判断模块具体用于：比较所述访问密码与预先存储在所述智能终端的非易失性存储器中的机主密码或访客密码是否相同；当所述访问密码与预先存储的机主密码相同，确定所述访问密码与机主密码相匹配；或者，当所述访问密码与预先存储的访客密码相同，确定所述访问密码与访客密码相匹配。
其中，机主密码和访客密码预先存储在智能终端的非易失性存储区域中。
该非易失性存储器中进一步存储有访问密码与用户数据分区之间的映射关系，在判断所述访问密码是否与访客密码或机主密码相匹配之后，查询访问密码与用户数据分区之间的映射关系，获得与用户输入的访问密码相对应的数据分区；如果用户输入
访客密码，则对应的用户数据分区是访客数据分区；如果用户输入机主密码，则对应的用户数据分区是机主数据分区。
第一分区挂载模块130，用于当判断模块120确定访问密码与访客密码相匹配时，挂载访客数据分区。
所述访客数据分区是智能终端内除系统数据分区和机主数据分区之外的存储区域，所述系统数据分区用于存储智能终端系统自带的系统程序，所述机主数据分区用于存储用户通过所述机主密码使用智能终端时所存储的信息。
在本发明一应用场景中，智能终端处于锁频状态，用户输入访客密码，则第一分区挂载模块具体用于：判断智能终端系统的当前挂载用户分区是否是访客数据分区；当所述第一判断子模块确定当前挂载用户分区不是所述访客数据分区时，卸载所述当前挂载用户分区，并挂载所述访客数据分区。
第二分区挂载模块140，用于当判断模块120确定访问密码与所述机主密码相匹配时，挂载机主数据分区。
本实施例提供的智能终端系统启动装置，智能终端设置有两个访问密码分别是访客密码和机主密码，用户输入不同的密码，智能终端系统将挂载不同的用户数据分区，该用户数据分区包括机主数据分区和访客数据分区。具体的，如果用户输入的访问密码是访客密码，智能终端系统将挂载访客数据分区；智能终端系统挂载访客数据分区后，就像进行了恢复出厂设置一样，仅有系统自带的应用程序，且没有用户通过机主密码使用智能终端时所存储的数据；即，访客看不到机主自行安装的应用程序，而且看不到机主使用智能终端的系统应用时所存储的任何数据，因此，采用该装置能够更全面地保护机主的隐私信息。
请参见图6，示出了本发明实施例示出的另一种智能终端系统启动装置的框图，该装置在图5所示实施例的基础上还可以包括划分模块210、第一展示模块220和存储模块230。
划分模块210，用于预先在智能终端的非易失性存储器上划分出访客数据分区；或者，用于通过基于随机存取存储器的文件系统，在智能终端的随机存取存储器上划分出访客数据分区。
该划分模块210可以在智能终端的RAM(Random Access Memory，随机存取存储器)中通过挂载tmpfs作为访客数据分区。其中，tmpfs是一种基于内存的文件系统，tmpfs可以使用RAM或swap分区来存储文件，tmpfs主要存储暂存的文件。即在RAM中为访客临时划分一个存储区域，用来存储访客数据。
第一展示模块220，用于当智能终端关机或所述智能终端挂载的用户数据分区由所述访客数据分区切换到所述机主数据分区时，向用户展示是否保存访客数据，所述访客数据是用户通过所述访客密码使用所述智能终端所产生的数据；
存储模块230，用于当检测到确认保存指令后，将所述访客数据存储到第一类存储区域中，所述确认保存指令由所述智能终端检测到用户确认保存所述访客数据的操作后产生。
若访客数据分区是智能终端的非易失性存储器内的存储区域，则第一类存储区域包括访客数据分区、智能终端的外置存储设备和云服务器中的至少一个；若访客数据分区是智能终端的随机存储存储器内的存储区域，则第一类存储区域包括智能终端的外置存储设备和云服务器中的至少一个。
本实施例提供的智能终端系统启动装置，当智能终端卸载访客数据分区时，智能终端会提示是否保存访客数据，如果用户确认需要保存访客数据，可以将访客数据存储到为访客预留的访客数据分区、外置存储设备和云服务器中的至少一种，从而使得访客下次使用该智能终端时，能够方便得看到自己使用该智能终端时所存储的数据，使访客使用更方便。
相应于上述的智能终端系统启动装置实施例，本发明还提供了智能终端实施例。
