具体实施方式
本申请实施例涉及的终端设备，也可以称为终端、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
现有技术中，随着终端设备的存储器件(例如：嵌入式多媒体卡(embedded multimedia card，EMMC)、UNIX文件***(UNIX file system，UFS)等)的容量越来越大、以及，克隆软件等的广泛使用，终端设备中存储的资源越来越多，例如照片、通讯录、音乐等。在终端设备中，资源的属性信息包括资源的标签，用于标记该资源的访问权限，即终端设备的哪些进程或哪些服务对该资源具有访问权限。
目前，终端设备的***软件版本升级包括如下几种场景：终端设备采用空间下载(over-the-air，OTA)技术下载***软件版本升级包的升级场景、终端设备采用加载存储在安全数码(secure digital memory card，SD)卡上的***软件版本升级包进行升级的升级场景、终端设备通过安装在一分区(例如A分区)上的新版本的***软件，对其它分区上(例如B分区)旧版本的***软件进行升级的升级场景。其中，这里所说的分区可以是对终端设备的存储器件在逻辑上的划分。
对于终端设备采用OTA技术下载***软件版本升级包的升级场景，以及，终端设备采用加载存储在SD卡上的***软件版本升级包进行升级的升级场景，终端设备的***软件版本升级可以包括两个阶段。一个阶段是recovery阶段，另一个阶段是Init阶段。在recovery阶段，终端设备可以根据***软件版本升级包对***软件进行版本升级，并重启终端设备。Init阶段是重启终端设备后所进入的阶段。在Init阶段，若***软件版本升级包携带的***软件的新版本对应的资源权限配置文件中存在至少一个路径信息对应的标签，与***软件的旧版本(即未升级前的***软件的版本)对应的资源权限配置文件中该路径信息对应的标签不同，则终端设备可以根据***软件的新版本对应的资源权限配置文件，对资源打标签，以更新所存储的资源的访问权限。
对于终端设备通过安装在一分区(例如A分区)上的新版本的***软件，对其它分区上(例如B分区)旧版本的***软件进行升级的升级场景，终端设备的***软件版本升级可以包括一个阶段，即Init阶段。在Init阶段，若新版本的***软件对应的资源权限配置文件中存在至少一个路径信息对应的标签，与旧版本的***软件(即未升级前的***软件的版本)对应的资源权限配置文件中该路径信息对应的标签不同，则终端设备可以根据新版本的***软件对应的资源权限配置文件，对资源打标签，以更新所存储的资源的访问权限。
以Linux操作***为例，资源权限配置文件对应一个哈希值，该哈希值根据资源权限配置文件的内容生成。因此，终端设备可以通过比对***软件的新版本对应的资源权限配置文件对应的哈希值，与***软件的旧版本对应的资源权限配置文件对应的哈希值，确定两个哈希值不同时，终端设备可以确定***软件的新版本对应的资源权限配置文件中存在至少一个路径信息对应的标签，与***软件的旧版本对应的资源权限配置文件中该路径信息对应的标签不同。在该场景下，终端设备触发全量打标签的操作。
上述所说的资源权限配置文件包括：文件、路径信息，以及，每个文件或路径信息对应的标签。现有技术中，无论资源对应的标签在此次***软件版本升级前后是否发生改变，***软件的新版本对应的资源权限配置文件也会携带该资源的路径信息，以及，该路径信息对应的标签。也就是说，资源权限配置文件所包括路径信息可以涵盖终端设备的所有资源的路径信息。其中，这里所说的路径信息可以是某一资源的路径，也可以是对应多个资源的路径信息。
示例性的，假定终端设备存储有资源1、资源2和资源3。其中，资源1的路径信息为/data/media/1.apk，资源2的路径信息为/data/media/1.jpg，资源3的路径信息为/data/media/2.jpg。资源权限配置文件包括：路径信息/data/media/1(/.*)？以及对应的标签、/data/media/2.jpg以及对应的标签。在该场景下，路径信息/data/media/1(/.*)？可以对应资源1和资源2，路径信息/data/media/1(/.*)？对应的标签，用于表征在***软件版本升级后，资源1和资源2对应的标签。路径信息/data/media/2.jpg对应资源3，路径信息/data/media/2.jpg对应 的标签，用于表征在***软件版本升级后，资源3对应的标签。
终端设备在Init阶段确定***软件的新版本对应的资源权限配置文件中存在至少一个路径信息对应的标签，与***软件的旧版本对应的资源权限配置文件中该路径信息对应的标签不同时，终端设备会触发全量打标签的操作。具体地，终端设备会采用递归的方式，对存储在存储器件中的资源逐一遍历。每遍历到一个资源，终端设备会读取该资源的路径信息，并在***软件的新版本对应的资源权限配置文件中查找与该资源的路径信息匹配的路径信息。然后，终端设备可以将匹配的路径信息所对应的标签，与该资源当前的标签(即未升级前的标签、或者，称为***软件的旧版本对应的标签)进行比对。在确定两个标签不同时，说明此次版本升级会对该资源的访问权限调整，因此，终端设备可以为该资源打上前述匹配的路径信息所对应的标签，以更新该资源的访问权限。
也就是说，无论资源的标签在***软件版本升级前后是否发生变化，终端设备都需要在资源权限配置文件中匹配该资源对应的路径信息，并将匹配的路径信息所对应的标签，与该资源当前的标签(即未升级前的标签)进行比对。由于终端设备中存储的资源越来越多(例如，终端设备中存储的资源的数量多达数十万、甚至数百万数量级)，因此，终端设备在采用上述方式打标签时，需要耗费较长的时间来为存储的资源打标签，使得打标签的效率较低，进而使得***软件版本升级的耗时长，用户体验较差。
考虑到上述情况，本申请实施例提供了一种资源权限处理方法，旨在解决现有技术中终端设备在***软件版本升级时，为资源打标签的效率较低，进而导致***软件版本升级的耗时长，用户体验较差的技术问题。本申请实施例所涉及的方法，可以适用于终端设备采用OTA技术下载***软件版本升级包的升级场景，也可以适用于终端设备采用加载存储在SD卡上的***软件版本升级包进行升级的升级场景，也可以适用于终端设备通过安装在一分区(例如A分区)上的新版本的***软件，对其它分区上(例如B分区)旧版本的***软件进行升级的升级场景。本领域技术人员可以理解，上述所示的升级场景并不构成对本申请实施例的应用场景的，本申请实施例可以包括但不限于上述升级场景，只要是任一涉及到采用上述所示的方式对资源打标签的升级场景，都可以采用本申请实施例的方法。
本申请实施例的方法的执行主体可以是终端设备、也可以是终端设备中的芯片。下面以执行主体是终端设备为例，以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
为了便于对本申请实施例的理解，下面对第二资源权限配置文件和第三资源权限配置文件进行定义和说明。具体地，
第二资源权限配置文件为***软件的新版本对应的资源权限配置文件。例如，终端设备采用OTA技术所下载的***软件版本升级包中所携带的资源权限配置文件，或者，终端设备通过SD卡所记载的***软件版本升级包中所携带的资源权限配置文件，或者，终端设备的一分区(例如A分区)上所安装的新版本的***软件所使用的资源权限配置文件。
第三资源权限配置文件为***软件的旧版本对应的资源权限配置文件。即，终端设备在进行***软件版本升级之前，所使用的***软件版本所对应的资源权限配置文件。
第一资源权限配置文件包括至少一个第一路径信息，以及，至少一个第一路径信息在第二资源权限配置文件中对应的标签。其中，第一路径信息为第二资源权限配置文件中与 第三资源权限配置文件中路径信息相同、但对应不同标签的路径信息。也就是说，第一资源权限配置文件中所包括的路径信息为第二资源权限配置文件和第三资源权限配置文件中标签有差异的路径信息。因此，在一些场景下，第一资源权限配置文件也可以称为差分资源权限配置文件。
下面对终端设备如何根据第二资源权限配置文件和第三资源权限配置文件，生成第一资源权限配置文件，进行详细的说明和介绍。图1为本申请实施例提供的一种资源权限处理方法的流程示意图。如图1所示，该方法可以包括：
S101、获取第二资源权限配置文件和第三资源权限配置文件。
S102、将第二资源权限配置文件中的每个路径信息对应的标签，与每个路径信息在第三资源权限配置文件中对应的标签进行比较，将标签不同的路径信息作为第一路径信息。
S103、根据每个第一路径信息，以及，每个第一路径信息在第二资源权限配置文件中对应的标签，生成第一资源权限配置文件。
S104、存储第一资源权限配置文件。
例如，对于终端设备采用OTA技术下载***软件版本升级包的升级场景，以及，终端设备采用加载存储在SD卡上的***软件版本升级包进行升级的升级场景，终端设备在recovery阶段，可以在对***软件版本升级包进行解析前，先从终端设备当前所使用的***软件中，获取所存储的第三资源权限配置文件。相应地，终端设备可以在对***软件版本升级包进行解析时，从***软件版本升级包中获取第二资源权限配置文件。
对于终端设备通过安装在一分区(例如A分区)上的新版本的***软件，对其它分区上(例如B分区)旧版本的***软件进行升级的升级场景，终端设备可以在进入Inti阶段之前，先从其它分区中获取所存储的第三资源权限配置文件。相应地，终端设备可以在一分区上的新版本的***软件中获取第二资源权限配置文件。
终端设备在获取第二资源权限配置文件和第三资源权限配置文件之后，可以将第二资源权限配置文件中的每个路径信息对应的标签，与，每个路径信息在第三资源权限配置文件中对应的标签进行比较，将标签不同的路径信息作为第一路径信息。例如，终端设备可以先匹配两个资源权限配置文件中的路径信息，在两个路径信息相同时，终端设备再比较该两个路径信息所对应的标签。当该两个路径信息所对应的标签不同时，终端设备可以将该路径信息作为第一路径信息。以此类推，直至完成所有路径信息的标签的比对。
然后，终端设备可以根据每个第一路径信息，以及，每个第一路径信息在第二资源权限配置文件中对应的标签，生成第一资源权限配置文件。此时，该第一资源权限配置文件包括每个第一路径信息，以及，每个第一路径信息在第二资源权限配置文件中对应的标签。即，第一资源权限配置文件包括的是第二资源权限配置文件和第三资源权限配置文件中标签有差异的路径信息，以及，该路径信息对应的标签。
在生成第一资源权限配置文件之后，终端设备可以根据预设的第一资源权限配置文件的路径信息，存储该第一资源权限配置文件。即，将该第一资源权限配置文件存储在终端设备的非易失性的存储器件中，以避免终端设备因重启进入Init阶段，导致第一资源权限配置文件丢失。可选的，在一些实施例中，上述终端设备还可以在存储该第一资源权限配置文件之前，对第一资源权限配置文件进行加密和签名，以避免非法软件或者黑客恶意更改该第一资源权限配置文件中的内容，确保终端设备在***软件版本升级过程中的安全，提 高了用户体验。
下面对终端设备如何在Init阶段根据第一资源权限配置文件，对存储的资源的标签进行更新进行详细的说明和介绍。图2为本申请实施例提供的另一种资源权限处理方法的流程示意图。如图2所示，该方法可以包括：
S201、在对终端设备的***软件进行版本升级时，获取第一资源权限配置文件。
S202、根据第一资源权限配置文件，更新终端设备的资源的标签。
具体的，终端设备在进入到Init阶段之后，可以根据预设的第一资源权限配置文件的路径信息，获取该第一资源权限配置文件。然后，终端设备可以根据该第一资源权限配置文件，更新终端设备的资源的标签。例如，终端设备会采用递归的方式，对存储在存储器件中的资源逐一遍历。每遍历到一个资源，终端设备会读取该资源的路径信息，并在第一资源权限配置文件中查找与该资源的路径信息匹配的路径信息。然后，终端设备可以将匹配的路径信息所对应的标签，与该资源当前的标签(即未升级前的标签、或者，称为***软件的旧版本对应的标签)进行比对。在确定两个标签不同时，说明此次版本升级会对该资源的访问权限调整，因此，终端设备可以为该资源打上前述匹配的路径信息所对应的标签，以更新该资源的访问权限。
由于该第一资源权限配置文件所包括的路径信息仅是标签发生变化的路径信息，并非是涵盖所有资源的路径信息。所以，终端设备在第一资源权限配置文件中查找与所遍历的资源的路径信息匹配的路径信息时的匹配量减少。因此，可以减少为存储的资源打标签的所耗费的时间，进而可以提高打标签的效率，从而可以缩短***软件版本升级的耗时、提高***软件版本升级的效率。
可选的，在一些实施例中，终端设备在根据第一资源权限配置文件，更新终端设备的资源的标签的过程中，可以在第一路径信息含有正则表达式字符时，根据第一路径信息在第二资源权限配置文件中所对应的标签，更新第一路径的上一级路径下的所有资源的标签。其中，这里所说的正则表达式字符例如可以为：“.”、“^”、“$”、“？”、“*”、“+”、“|”、“[”、“(”、“{”等中的一个或多个字符的组合。也就是说，当第一资源权限配置文件包括含有正则表达式字符时，终端设备可以不再对第一路径的上一级路径下的所有资源执行遍历操作，而是对第一路径的上一级路径下的每个资源执行路径匹配和标签比对的操作，进而在某一资源的路径匹配、标签不同时，使用该第一路径信息对应的标签更新资源的标签，不用再对第一路径的上一级路径下的资源进行遍历操作，进一步提高了为资源打标签的效率。
示例性的，以第一路径信息为/data/media/1(^)？为例，该第一路径信息可以涵盖/data/media/11、/data/media/1.apk等路径信息。在该场景下，终端设备可以对data/media下的每个资源执行路径匹配和标签比对的操作，进而在某一资源的路径匹配、标签不同时，使用该/data/media/1(^)？对应的标签更新资源的标签，不用再对/data/media下的资源进行遍历操作，进一步提高了为资源打标签的效率。
在一些实施例中，终端设备还可以在第一路径信息含有预设格式的正则表达式字符串时，根据第一路径信息在第二资源权限配置文件中所对应的标签，更新第一路径下的所有资源的标签。其中，这里所说的预设格式的正则表达式字符串具体可以根据用户的需求设定，例如“.”或者“(/.*)？”。通过预先设定预设格式的正则表达式字符串，使得终端设备 可以不再对含有预设格式的正则表达式字符串的第一路径下的所有资源执行遍历操作和路径匹配操作，而是对第一路径下的每个资源执行标签比对的操作，进而在某一资源的标签不同时，使用该第一路径信息对应的标签更新资源的标签，进一步提高了为资源打标签的效率。
示例性的，以第一路径信息为/data/media/1(/.*)？为例，该第一路径信息可以涵盖/data/media/1.jpg、/data/media/1.apk等路径信息。则在该场景下，终端设备可以根据/data/media/1(/.*)？对应的标签，逐一对比/data/media/1下的每个资源的标签是否与该标签相同，在标签不同时，使用/data/media/1(/.*)？对应的标签更新该资源的标签，不用再对/data/media/1下的资源进行遍历操作，以及，路径匹配的操作，进一步提高了为资源打标签的效率。
可选的，在一些实施例中，终端设备在进入到Init阶段之后，根据预设的第一资源权限配置文件的路径信息，获取该第一资源权限配置文件失败时，终端设备还可以根据第二资源权限配置文件，采用现有技术中更新资源的标签的方式，更新终端设备的资源的标签，以为资源标签的更新提供备份方案，确保了资源标签更新的可靠性，进而提高了***软件版本升级的可靠性。
可选的，在一些实施例中，若终端设备更新终端设备的资源的标签的时长超过预设时长，说明终端设备执行为资源打标签的操作可能出现了错误。在该场景下，终端设备可以执行重启终端设备的操作，并重新获取第一资源权限配置文件，以重新执行为资源打标签的操作，确保了资源标签更新的可靠性，进而提高了***软件版本升级的可靠性。
可选的，在一些实施例中，若终端设备在生成第一资源权限配置文件之后、且存储该第一资源权限配置文件之前，对第一资源权限配置文件进行加密和签名，则在本实施例中，终端设备在获取第一资源权限配置文件之后，还需对第一资源权限配置文件执行解密操作，对此不再加以赘述。
图3A为本申请实施例涉及的终端设备的结构框图。参考图3A，该终端设备可以包括：处理器、存储器件和显示单元等部件。下面结合图3A对终端设备的各个构成部件进行具体的介绍：
在本申请实施例中，存储器件可以包括随机存取存储器(random-access memory，RAM)、非易失性存储器。其中，随机存取存储器用于负责缓存处理器在执行上述资源权限处理方法时的过程数据。非易失性存储器件可用于存储***软件，处理器通过运行存储在存储器件的***软件，从而执行终端设备的各种功能应用以及数据处理。非易失性存储器件可主要包括存储***软件的分区和存储数据的分区，其中，存储***软件的分区可存储操作***、至少一个功能所需的***软件(比如声音播放功能、图像播放功能等)等；存储数据的分区可存储根据终端设备的使用所创建的资源等。可选的，在终端设备通过安装在一分区(例如A分区)上的新版本的***软件，对其它分区上(例如B分区)旧版本的***软件进行升级的升级场景中，上述新版本的***软件例如可以安装在存储数据的分区，旧版本的***软件可以安装在存储***软件的分区，或者，上述终端设备的非易失性存储器件中包括至少两个存储***软件的分区，一个分区安装有新版本的***软件，至少两个存储***软件的分区中的其他某一个分区中安装有旧版本的***软件。
图3B为本申请实施例涉及的终端设备的处理器的结构框图。如图3B所示，在本实施例中，处理器用于执行上述资源权限处理方法。可选的，处理器可包括一个或多个处理单元；例如，处理器可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作***、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器中。
具体实现时，处理器可以包括：***软件升级模块、第一资源权限配置文件生成模块、第一资源权限配置文件解析模块、标签更新模块等。可选的，处理器还可以包括：第一资源权限配置文件加密模块、第一资源权限配置文件解密模块。
对于终端设备采用OTA技术下载***软件版本升级包的升级场景，以及，终端设备采用加载存储在SD卡上的***软件版本升级包进行升级的升级场景，***软件升级模块、第一资源权限配置文件生成模块、第一资源权限配置文件加密模块等在recovery阶段工作，第一资源权限配置文件解密模块、第一资源权限配置文件解析模块、标签更新模块在Init阶段工作。对于终端设备通过安装在一分区(例如A分区)上的新版本的***软件，对其它分区上(例如B分区)旧版本的***软件进行升级的升级场景，***软件升级模块、第一资源权限配置文件生成模块、第一资源权限配置文件加密模块等在进入Init阶段之前工作，第一资源权限配置文件解密模块、第一资源权限配置文件解析模块、标签更新模块在Init阶段工作。
其中，***软件升级模块，用于根据第二资源权限配置文件的路径信息，获取第二资源权限配置文件，根据第三资源权限配置文件的路径信息，获取第三资源权限配置文件。
第一资源权限配置文件生成模块，用于对第二资源权限配置文件转换为明文，并将第二资源权限配置文件中的每个路径信息对应的标签，与每个路径信息在第三资源权限配置文件中对应的标签进行比较，将标签不同的路径信息作为第一路径信息，并根据每个第一路径信息，以及，每个第一路径信息在第二资源权限配置文件中对应的标签，生成第一资源权限配置文件。
第一资源权限配置文件加密模块，用于对第一资源权限配置文件进行加密、签名，并存储至存储器件。
第一资源权限配置文件解密模块，用于从存储器件中获取第一资源权限配置文件，并对第一资源权限配置文件进行校验和解密。

显示单元可用于显示在***软件版本升级过程中，向用户提供***软件版本升级的相关信息或者动画等。示例性的，显示单元可以显示终端设备为资源打标签过程的用户提醒信息，例如：打标签的进度、当前正在为哪个资源打标签、以及，该资源的标签是什么等中的一个或多个信息。显示单元可包括显示面板，可选的，可以采用液晶显示器(Liquid Crystal Display，LCD)、有机发光二极管(Organic Light-Emitting Diode,OLED)等形式 来配置显示面板。
本领域技术人员可以理解，图3A中示出的终端设备的结构并不构成对终端设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。例如，上述终端设备还可以包括射频(Radio Frequency，RF)电路、输入单元、无线保真(wireless fidelity，WiFi)模块1170、电源1190等部件，对此不再一一赘述。
下面以终端设备安装有Linux操作***、终端设备采用OTA技术完成***软件版本升级包的下载为例，对本申请实施例提供的资源权限处理方法进行说明和介绍。图4A为本申请实施例提供的又一种资源权限处理方法的流程示意图。如图4A所示，在recovery阶段，在终端设备采用OTA技术完成***软件版本升级包的下载之后，该方法可以包括：
S301、在解析***软件版本升级包之前，获取存储在终端设备中的第三资源权限配置文件。
S302、在解析***软件版本升级包时，获取***软件版本升级包中携带的第二资源权限配置文件。
S303、对第二资源权限配置文件和第三资源权限配置文件进行比对，将第二资源权限配置文件中的每个路径信息对应的标签，与，每个路径信息在第三资源权限配置文件中对应的标签进行比较，将标签不同的路径信息作为第一路径信息。
S304、根据每个第一路径信息，以及，每个第一路径信息在第二资源权限配置文件中对应的标签，生成第一资源权限配置文件。
S305、对第一资源权限配置文件进行加密和签名。
S306、存储第一资源权限配置文件。
在执行完步骤S306之后，终端设备重启，进入Init阶段。
图4B为本申请实施例提供的又一种资源权限处理方法的流程示意图。如图4B所示，在进入Init阶段后，该方法可以包括：
S401、获取第一资源权限配置文件。
S402、对第一资源权限配置文件进行解密并解析。
S403、确定对第一资源权限配置文件进行解密并解析是否成功，若是，则执行S404，若否，则执行S407。
S404、根据第一资源权限配置文件，更新终端设备的资源的标签。
S405、使用第二资源权限配置文件对应的哈希值，更新终端设备中存储的当前所使用的资源权限配置文件对应的哈希值。
如前述实施例所说，资源权限配置文件对应一个哈希值，该哈希值根据资源权限配置文件的内容生成。现有技术中，安装有Linux操作***的终端设备存储有当前所使用的资源权限配置文件对应的哈希值。因此，本实施例中，当安装有Linux操作***的终端设备采用上述方式，对终端设备上存储的资源的标签进行更新后，即，当前终端设备所使用的资源权限配置文件应为第二资源权限配置文件，并非是第三资源权限配置文件。终端设备还可以进一步使用第二资源权限配置文件对应的哈希值，更新终端设备中存储的当前所使用的资源权限配置文件对应的哈希值，即取代终端设备中存储的第三资源权限配置文件对应的哈希值。通过这种方式，可以确保终端设备所存储的用于表征当前所使用的资源权限配置 文件的哈希值的准确性。
S406、启动终端设备的上层服务。
执行完S406之后，此次***软件版本升级流程执行完毕。
S407、确定第二资源权限配置文件中是否存在至少一个路径信息对应的标签，与第二的资源权限配置文件中该路径信息对应的标签不同。若是，则执行S407，若否，则返回执行S406。
S408、根据第二资源权限配置文件，更新终端设备的资源的标签。
执行完S408之后，返回执行S406。
可选的，在执行上述操作的过程中，终端设备可以实时的监控更新资源的标签的时长超过预设时长。若是，则终端设备可以重启终端设备，以重新执行图4B所示的流程。通过这种方式，可以确保资源标签更新的可靠性，进而提高***软件版本升级的可靠性。
本申请实施例提供的方法，通过根据***软件升级前后所使用的资源权限配置文件，生成第一资源权限配置文件，以使得第一资源权限配置文件仅涵盖标签发生变化的路径信息。因此，终端设备在根据第一资源权限配置文件，对终端设备上存储的资源更新标签时，终端设备在第一资源权限配置文件中查找与所遍历的资源的路径信息匹配的路径信息时的匹配量减少，可以减少为存储的资源打标签的所耗费的时间，进而可以提高打标签的效率，从而可以减少***软件版本升级所耗费的时间，提高了***软件版本升级的效率。
由于用户使用习惯不同，因此，即便是同一类型的终端设备，不同用户的终端设备上的资源数量不同、存储器件碎片化程度不同、标签内容也不同。所以，不同用户的终端设备在使用现有技术中的方式为存储的资源打标签时，所耗费的时间也不同，导致使用同一类型的终端设备的用户对***软件升级的体验也不同。例如，使用半年以上的终端设备打标签需要耗时50秒左右，一些终端设备甚至打标签耗时超过***预设的最大开机时长，导致终端设备反复重启，以重新对***软件进行版本升级。而通过本申请实施例所提供的方法，由于终端设备在第一资源权限配置文件中查找与所遍历的资源的路径信息匹配的路径信息时的匹配量大大减少，即便是用户使用习惯不同，同一类型的终端设备的同一版本的***软件升级的耗时近似相同，提高了用户体验。
图5为本申请实施例提供的一种资源权限处理装置的结构示意图。该资源权限处理装置可以为终端设备，也可以为应用于终端设备的芯片。如图5所示，该装置可以包括：第一获取模块11和更新模块12。其中，
第一获取模块11，用于在对终端设备的***软件进行版本升级时，获取第一资源权限配置文件，第一资源权限配置文件包括：至少一个第一路径信息，以及，与每个第一路径信息在第二资源权限配置文件中对应的标签，第二资源权限配置文件为***软件的新版本对应的资源权限配置文件，第三资源权限配置文件为***软件的旧版本对应的资源权限配置文件，第一路径信息为第二资源权限配置文件中与第三资源权限配置文件中路径信息相同、但对应不同标签的路径信息；

重启模块16，用于在更新模块12更新终端设备的资源的标签的时长超过预设时长时，重启终端设备；
第一获取模块11，还用于重新获取第一资源权限配置文件。
