Description

基于身份验证的空间切换方法、装置及终端 技术领域
本发明涉及终端技术领域,具体而言,涉及一种基于身份验证的空间切换方法、一种基于身份验证的空间切换装置及一种终端。
背景技术
目前,多操作系统的系统终端已进入到日常的生活中,但是多操作系统占用移动终端的资源,如占用CPU(Central Processing Unit,中央处理机)或内存较大。针对这一问题,由于用户对移动终端的性能及安全性的要求越来越高,在移动终端上进行多域操作是一个不错的解决方案,这提供了轻量级的系统虚拟化的解决方案,允许多个用户运行在一个操作系统上,这样每个用户就可以有自己的用户空间,并且每个用户空间的资源都会相互隔离。
然而,用户往往需要在不同的情况下切换到不同的用户空间中,比如在进行购物、支付等操作时,需要进入到安全空间操作,在将移动终端给儿童玩耍时,需要进入到儿童空间操作中去,这样就需要利用空间切换方式进行用户空间切换,相关技术中大多是通过下拉托盘提供的切换入口进行用户空间的切换。
但是,终端在待机、屏幕没有点亮或者屏幕被锁住的情况下,上述切换方式需要依次点亮屏幕、解锁屏幕、点击切换开关,才能在身份认证成功后切换到指定的用户空间中,使得用户空间的切换操作比较繁琐,不方便用户的使用。
因此,需要一种新的技术方案,能够简化用户空间的切换的操作,提升各用户空间的安全性。
发明内容
本发明正是基于上述问题,提出了一种新的技术方案,能够简化用户 空间的切换的操作,提升各用户空间的安全性。
有鉴于此,本发明的一方面提出了一种基于身份验证的空间切换方法,用于具有多个用户空间的终端,包括:在当前用户空间接收身份验证密钥;根据所述身份验证密钥,在预设密钥数据库中检索是否具有与所述身份验证密钥一致的预设密钥;根据检索结果,确定是否根据所述身份验证密钥进行空间切换。
在该技术方案中,终端中的多个用户空间共用一个操作系统,可以降低对终端性能的要求,多个用户空间之间可以进行资源共享,也可以通过Namespace(命名空间)技术进行资源隔离,以保证各个用户空间的隐私及安全性。在此基础上,应用本发明的技术方案,可以在终端的解锁状态下直接根据接收到的身份验证密钥验证是否可以进行空间切换,或者在终端的锁屏状态下通过接收到的身份验证密钥同时完成身份认证和用户空间切换的双重功能,这样,既为空间切换提供了身份验证,也无需用户在每次进行空间切换时打开特定空间切换界面或空间切换验证界面,比如,可以实现在终端的锁屏状态下直接完成身份认证和用户空间切换的双重功能,不但简化了用户操作,也提升了各用户空间的安全性,提升了用户体验。
在上述技术方案中,优选地,所述根据检索结果,确定是否根据所述身份验证密钥进行空间切换,具体包括:当确定所述预设密钥数据库中具有与所述身份验证密钥一致的所述预设密钥时,从所述当前用户空间切换至所述预设密钥对应的目标用户空间,否则,禁止进行空间切换。
在该技术方案中,终端的预设密钥数据库中具有每个用户空间对应的预设密钥,只有接收到的身份验证密钥与预设密钥数据库中存储的某个预设密钥一致时,说明可以通过身份认证,切换至该预设密钥对应的用户空间。通过该技术方案,实现了身份认证和用户空间切换的双重功能,简化了用户操作,并提升了各用户空间的安全性。
在上述技术方案中,优选地,在所述在当前用户空间接收身份验证密钥之前,还包括:根据接收到的设置命令,为所述多个用户空间中的每个用户空间设置至少一个预设密钥。
在该技术方案中,可以预先为每个用户空间设置对应的预设密钥,每个用户空间设置对应的预设密钥可以为一个或多个,具有多个预设密钥的用户空间具有更高的安全性。比如,用户可以为用于工作的用户空间设置一个密码类型的预设密钥,为用于存储私密联系人的用户空间设置虹膜和密码两种预设密钥。
在上述技术方案中,优选地,在所述在当前用户空间接收身份验证密钥之前,还包括:将设置的所述每个用户空间对应的所述至少一个预设密钥保存至所述预设密钥数据库中,以供检索所述预设密钥数据库中是否具有与在所述当前用户空间接收到的所述身份验证密钥一致的所述预设密钥。

在该技术方案中,终端的预设密钥数据库中具有每个用户空间对应的预设密钥,只有接收到的身份验证密钥与预设密钥数据库中存储的某个预设密钥一致时,说明可以通过身份认证,切换至该预设密钥对应的用户空间。通过该技术方案,实现了身份认证和用户空间切换的双重功能,简化了用户操作,并提升了各用户空间的安全性。
在上述技术方案中,优选地,还包括:设置单元208,在当前用户空间接收身份验证密钥之前,根据接收到的设置命令,为多个用户空间中的每个用户空间设置至少一个预设密钥。
在该技术方案中,可以预先为每个用户空间设置对应的预设密钥,每个用户空间设置对应的预设密钥可以为一个或多个,具有多个预设密钥的用户空间具有更高的安全性。比如,用户可以为用于工作的用户空间设置一个密码类型的预设密钥,为用于存储私密联系人的用户空间设置虹膜和密码两种预设密钥。

图3示出了根据本发明的一个实施例的终端的框图。
如图3所示,根据本发明的一个实施例的终端300,该终端300包括多个用户空间302以及图2示出的基于身份验证的空间切换装置200,因此,该终端300具有与图2示出的的基于身份验证的空间切换装置200相同的技术效果,在此不再赘述。
图4和图5示出了根据本发明的一个实施例的用户空间与密钥库的对应示意图。
如图4所示,在移动终端中,n个Space(空间)共享一个Android OS(Android Operating System,安卓操作系统),每一个Space对应一个用户,并且这n个用户空间可以利用隔离技术实现数据的相互隔离,使每个用户能够单独运行在各自的空间中。其中,终端资源如果没有利用隔离技术进行隔离,该资源就是共享资源将会被所有的用户共享,例如,相机是共享资源,n个空间中的用户都可以调用相机进行拍照。
本实施例中,运用Namespace(命名空间)进行系统全局资源的隔离,从而让每个用户空间相互隔离起来,Namespace是Linux(个人电脑上免费的一种操作系统)内核提供的一种用于隔离系统全局资源的机制,主要用于基于容器技术的操作系统级的虚拟化解决方案中,能够实现将使用全局系统资源的不同容器间进行隔离。
本实施例中,终端包括:身份认证模块、用户空间切换模块、身份认证密钥库,其中,身份认证密钥库用于身份认证。
具体地,身份认证模块、用户空间切换模块以及身份认证密钥库是n 个用户空间共享的,即在任意一个用户空间中,用户都可以调用身份认证模块和用户空间切换模块,来进入的身份认证密钥库。
1.身份认证模块主要完成以下的功能:设置用户的身份认证方式并与相应的用户空间绑定;在屏幕解锁时完成用户的身份认证,具体包括:
(1)用户设置的身份认证方式是多种多样的,比如指纹识别、图案解锁以及数字密码等。当用户选定一种认证方式之后,就可以为每个用户空间设置的解锁密钥。例如,为用户空间设置指纹认证方式解锁方式,用户空间1的解锁指纹设为右手拇指,用户空间2的解锁指纹设为右手食指。
另外,在本实施例中将解锁的指纹、图案或密码统称为身份认证密钥K,每个用户空间的K都不一样,在锁屏状态时,每一个用户空间都对应一个身份认证密钥K,用户空间i与Ki一一绑定(如图4所示)。
如图5所示,在屏幕解锁状态时,可默认此时用户处于某个用户空间中,需要切换到另一个用户空间中,如果要进行用户空间的切换,则任何一个身份认证密钥K(K1,K2,…,Kn)均可以认证成功,即此时的用户空间i对应n个密钥K(K1,K2,…,Kn)。
(2)在进行身份认证时,此时屏幕处于锁定状态,如果用户提供身份认证密钥Ki进行身份认证成功后,屏幕解锁成功,并启动用户空间切换模块,进入到用户空间i中;否则,屏幕解锁失败。
(3)在进行身份认证时,如果此时屏已经处于解锁状态,则用户任意提供的正确的身份认证密钥Ki(i=1、2、…、n)均可以身份认证成功,并完成用户空间的切换。
2.用户空间切换模块用于完成用户空间切换的功能,包括屏幕解锁状态的用户空间的切换和屏幕锁屏状态的用户空间的切换。
其中,屏幕解锁状态的用户空间切换,是指用户已完成了屏幕解锁,正常处于空间i中,这时要切换到空间j中;屏幕锁屏状态的用户空间切换,是指当前屏幕处于锁定状态,根据用户提供的身份认证密钥Ki,完成身份认证而屏幕解锁,并且直接进入到空间i中。
3.身份认证密钥库用于存储用户身份认证资料,在实施例中,不仅要 存储用于屏幕解锁的身份认证密钥K,还要存储与身份认证密钥Ki对应的用户空间i。其中,为了保证空间i与Ki相关联,身份认证密钥库的实现方式可以是多种多样,可以是一个数据库,也可以是一个文件。
图6示出了根据本发明的另一个实施例的终端的示意图。
如图6所示,根据本发明的另一个实施例的终端包括Android OS(Android Operating System,安卓操作系统)、apps(多个应用程序)、data(用户空间的数据)。
本实施例运用Namespace技术对系统全局资源进行隔离,合理规划每个用户空间中用户进程的权限,例如,设置每个用户空间中可以运行的app(应用程序)以及能够调用的功能模块等,各用户空间的data相互隔离,可以通过各用户空间的相关的应用程序调用系统的共享资源。
另外,多用户空间终端中用户间切换的具体实现的方式可以如下:
其一,在屏幕处于锁定状态时,用户想要进入到n个用户空间的用户空间i中,步骤如下:
步骤1,用户提供身份识别密钥(验证指纹/图案/密码等),通过该身份识别密钥调用用户身份认证模块。
步骤2,从身份认证密钥库中检索身份认证密钥库K(K1,K2,…,Kn)。
步骤1-3,如果身份识别密钥与身份认证密钥库K(K1,K2,…,Kn)中的Ki匹配,则身份认证成功,并启动用户空间切换模块,执行步骤4,而如果身份识别密钥与身份认证密钥库K(K1,K2,…,Kn)中的任何一个密钥都不匹配,则执行步骤5。
步骤4,屏幕解锁,用户空间切换模块控制进入到空间i中。
步骤5,身份认证失败,屏幕未解锁。
其二,在屏幕处于解锁状态时,用户此时处于用户空间i中,想要进入到n个用户空间中的用户空间j中,步骤如下:
步骤1,用户通过系统提供的空间切换入口,选择切换到空间j,启用身份认证模块。
步骤2,检索身份认证密钥库K(K1,K2,…,Kn)。
步骤3,如果用户提供的身份认证密钥与身份认证密钥库K(K1,K2,…,Kn)中的某个密钥Kj相匹配,则身份认证成功,并启用用户空间切换模块,执行步骤4;如果身份识别密钥与身份认证密钥库K(K1,K2,…,Kn)中的任何一个密钥都不匹配,则执行步骤5。
步骤4,用户空间切换模块控制进入用户空间j。
步骤5,身份认证失败,空间切换失败,用户仍处于用户空间i中。
以上结合附图详细说明了本发明的技术方案,通过以上技术方案,可以直接根据接收到的身份验证密钥验证是否可以进行空间切换,既为空间切换提供了身份验证,也无需用户在每次进行空间切换时打开特定空间切换界面或空间切换验证界面,尤其对于锁屏状态下的终端,可以实现在终端的锁屏状态下直接完成身份认证和用户空间切换的双重功能,不但简化了用户操作,也提升了各用户空间的安全性,提升了用户体验。
