Description

图片的存储方法、装置和终端设备
本申请实施例要求于2022年8月10日提交中国专利局、申请号为202210959305.X、发明名称为“图片的存储方法、装置和终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请实施例中。
技术领域
本申请实施例涉及智能终端技术领域，特别涉及一种图片的存储方法、装置和终端设备。
背景技术
图片是重要的个人数据。用户在很多场景下，都有把部分照片进行隐私处理，防止别人查看、修改或删除的诉求。
现有相关技术提供的一种实现方案中，可以使用加密的方式对图片进行加密处理，具体地，可以在相册中增加加密相册的入口，对用户移入加密相册的每张图片进行加密处理。图片加密之后，只有当前应用才能解密该图片，之后进行正常的图片显示。
但是，这种方式存在图片被删除的风险。图片加密之后，用户虽然不能从其他入口增加或者查看加密的图片。但是用户可以在其他入口处，删除该图片。同样地，用户还可以通过其他入口对这些加密之后的图片，再进行其他处理，比如用其他的应用再加密一次，从而导致用户从加密相册入口进入之后，也不能查看图片。另外，对图片进行加密或者解密，需要消耗中央处理器(central processing unit，CPU)的算力，并且还消耗时间。比如用户一次将100张照片挪入到加密相册，由于加密算法的耗时，需要额外多等待加密的时间。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
针对如何对照片进行隐私处理这一问题，现有相关技术提供的一种方案为使用加密的方式对图片进行加密处理，但这种方式存在图片被删除的风险，并且对图片进行加密或者解密，需要消耗CPU的算力，并且还消耗时间。
而对于现有相关技术提供的，使用内部存储区机制对图片进行加密存储的方案，具体来说，就是在当前手机系统上，系统将应用的存储区分为应用外部存储区、外部公共目录存储区和应用内部存储区，如图1所示，图1为现有相关技术中应用的存储区的划分示意图。
对于图1中的应用外部存储区，任意应用都可以访问，而应用内部存储区，每个应用能且只能访问自身的内部存储区。
应用将加锁相册里面的图片存入其内部存储区之后，其他应用是无法访问的。但是从操作系统上来讲，这种方案存在以下缺点：
缺点一，可以通过卸载的途径，删除内部存储数据。操作系统在系统设置，或者是其他设置里面提供了卸载入口，用户就可以从该入口卸载安装在当前手机上的应用，如图2和图3所示，图2为现有相关技术中系统设置提供卸载入口的示意图，图3为现有相关技术中应用市场提供卸载入口的示意图。
用户可以通过图2和图3所示的卸载入口，对应用进行卸载。应用被卸载后，操作系统会清空这个应用的内部存储区的数据，这样加锁相册里面的图片，也就被删除了。
缺点二。用户可以通过清空应用数据来删除加锁相册中的图片，操作系统在设置中提供了清除图片数据的入口。如图4所示，图4为现有相关技术中清空应用数据的入口的示意图。
系统的图库，媒体库的内部存储数据，都可以通过图4删除数据按钮进行清空处理。由于图库，媒体库这些应用的特殊性，其中包含了很多系统数据，如果出错需要有可恢复措施，因此操作系统认为这个删除数据的入口必须保留。
综上，在以上两个缺点中，用户都可以绕过加锁相册入口，直接删除加锁相册中的图片。
基于以上问题，本申请实施例提供一种图片的存储方法，可以实现图片加锁存储，上述图片的存储方法中没有使用加密算法，在图片的存储过程中，不需要加密解密，也不需要额外的计算。另外，本申请实施例可以做到用户能且只能通过图库的加锁相册入口，访问加锁图片、增加、删除和/或修改图片。
本申请实施例充分使用操作系统的资源，提出一种新的实现方式，可以做到在图库应用被卸载之后，仍然保留图库的加锁相册，还可以做到用户在清空图库数据的时候，仍然保留图库的加锁相册。
本申请实施例提供的图片的存储方法可以应用于终端设备，其中，上述终端设备可以为智能手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer， UMPC)、上网本或个人数字助理(personal digital assistant，PDA)等设备；本申请实施例对终端设备的具体类型不作任何限制。
示例性的，图5为本申请一个实施例提供的终端设备的结构示意图，如图5所示，终端设备100可以包括处理器110，外部存储器接口120，内部存储器121，通用串行总线(universal serial bus，USB)接口130，充电管理模块140，电源管理模块141，电池142，天线1，天线2，移动通信模块150，无线通信模块160，音频模块170，扬声器170A，受话器170B，麦克风170C，耳机接口170D，传感器模块180，按键190，马达191，指示器192，摄像头193，显示屏194，以及用户标识模块(subscriber identification module，SIM)卡接口195等。其中传感器模块180可以包括压力传感器180A，陀螺仪传感器180B，气压传感器180C，磁传感器180D，加速度传感器180E，距离传感器180F，接近光传感器180G，指纹传感器180H，温度传感器180J，触摸传感器180K，环境光传感器180L，骨传导传感器180M等。

为了便于理解，本申请以下实施例将以具有图5所示结构的终端设备为例，结合附图和应用场景，对本申请实施例提供的图片的存储方法进行具体阐述。
首先，对用户添加相册锁的过程进行介绍。
用户在图库浏览相册的时候，可以通过点击菜单，对该相册进行添加相册锁，如图6所示，图6为本申请一个实施例提供的触发添加相册锁的界面示意图，如果是首次添加相册锁，对应的会弹出免责提示，如图7所示，图7为本申请一个实施例提供的相册锁的免责提示的界面示意图。
在图7所示界面中，如果用户点击“继续”，则终端设备100可以获取用户的确认指示，然后终端设备100可以显示输入密码的界面，在获取用户输入的密码之后，完成为相册添加相册锁的操作，如图8(a)～图8(c)所示，图8(a)～图8(c)为本申请一个实施例提供的设置相册锁密码的界面示意图。
用户在添加相册锁的时候，图库检测到系统有人脸识别或者指纹识别之后，会在用户添加完密码锁之后，主动弹窗提示可以进行生物识别关联，如图9(a)～图9(b)所示，图9(a)～图9(b)为本申请一个实施例提供的关联生物识别的界面示意图。在关联生物识别之后，用户后续打开相册时，不会再额外主动提示。
图库给相册添加锁之后，可以调用图库与相册锁对应的系统应用之间的接口，将加锁相册中的图片从图库对应的内部存储区转存到系统应用对应的内部存储区，以达到加锁相册的保密性和安全性要求。
下面介绍一下操作系统上，应用可以放置内容的3个存储区，参见图1，应用在操作系统上，可以使用的存储区分为：
外部：应用外部存储区和外部公共目录；
内部：应用内部存储区。
对于外部存储区，任意应用都可以进行访问，安全性达不到要求。对于内部存储区，当前操作系统通过文件系统级别的权限管控，只有应用本身可以进行访问。但是根据操作系统的设计，在用户卸载应用的时候，系统会清空对应应用的内部存储区。
本申请实施例中，在操作系统中新增加一个应用(即相册锁对应的应用)，同时将该应用的权限设置为系统应用，用户无法通过操作系统的卸载入口，将该应用卸载。同时该应用不在应用市场上发布更新，用户也无法通过卸载应用市场新安装的应用，找到卸载入口清空该应用内部存储区数据。
下面给出对比图，如图10所示，从图10可以看到，图库不是系统应用，因此应用管理处有卸载入口，而媒体存储为系统应用，因此应用管理处没有卸载入口，用户也就无法卸载媒体存储这个系统应用，也无法进一步清空媒体存储对应的内部存储区。图10为本申请一个实施例提供的卸载入口被屏蔽的对比示意图。
另外，本申请实施例中，图库与新增加的系统应用之间增加进程间通信接口。
下面结合图6～图10，对本申请实施例提供的图片的存储方法进行介绍。
图11为本申请一个实施例提供的图片的存储方法的流程图，如图11所示，上述图片的存储方法可以包括：
步骤1101，检测到用户对目标相册添加相册锁的第一触发操作。
其中，上述目标相册保存在图库对应的第一内部存储区中。
具体地，上述第一触发操作可以为用户对“添加相册锁”的图标的点击、长按或双击等操作，本实施例对上述第一触发操作的操作形式不作限定，举例来说，参见图6，用户在图库浏览目标相册的时候，可以通过点击菜单中的“添加相册锁”图标，对目标相册添加相册锁。
步骤1102，响应于第一触发操作，为上述目标相册添加相册锁，并启动上述相册锁对应的系统应用。
步骤1103，通过图库与上述系统应用之间的文件打开接口，将目标相册中的图片名称发送给上述系统应用。
步骤1104，如果上述系统应用对应的第二内部存储区中不包括上述图片名称对应的图片文件，则在第二内部存储区中创建上述图片文件，获取上述图片文件的第一文件描述符，并将上述图片文件的第一文件描述符返回给图库。
步骤1105，获取图库根据第一文件描述符向第二内部存储区写入的图片内容。
具体地，图库获得上述第一文件描述符之后，可以通过上述第一文件描述符向第二内部存储区写入图片内容。
步骤1106，关闭上述文件打开接口，将上述图片内容保存在第二内部存储区。
具体地，每写完一张图片，需要关闭一次文件打开接口，再完成图片内容的保存。之后可以重新执行步骤1103～步骤1106，继续保存图片。
上述图片的存储方法中，终端设备100检测到用户对目标相册添加相册锁的第一触发操作，响应于第一触发操作，为上述目标相册添加相册锁，并启动上述相册锁对应的系统应用，然后通过图库与上述系统应用之间的文件打开接口，将目标相册中的图片名称发送给上述系统应用，如果上述系统应用对应的第二内部存储区中不包括上述图片名称对应的图片文件，则在第二内部存储区中创建上述图片文件，获取上述图片文件的第一文件描述符，并将上述图片文件的第一文件描述符返回给图库，最后，获取图库根据第一文件描述符向第二内部存储区写入的图片内容，关闭上述文件打开接口，将上述图片内容保存在第二内部存储区，从而可以实现终端设备100对图片进行加锁存储，并且不需要加密解密，不需要额外的计算，并且即便用户清空图库数据，也只是清空图库对应的第一内部存储区，由于图片内容也被保存在系统应用对应的第二内部存储区中，因此终端设备100中仍保留有加锁存储的图片。
终端设备100中，操作系统为每个应用都提供了清理存储区的操作入口，用户通过这个操作入口清空应用的外部存储区和内部存储区存储的所有数据。本申请实施例中，相册锁对应的系统应用的清理存储区入口处于用户不可见状态，具体地，相册锁对应的系统应用可以通过两种方式，阻止用户清理其存储区数据，保障加锁相册的数据安全。
方式一，系统应用可以通过申请系统权限，将清理存储区的操作入口屏蔽，用户不可点击，就像系统的设置应用一样，如图12所示，图12为本申请一个实施例提供的清理存储区的操作入口被屏蔽的界面示意图，从图12可以看出，设置应用的清理存储区的操作入口就被屏蔽了，用户不可点击，因此相册锁的系统应用可以采用与设置应用相同的方式，屏蔽清理存储区的操作入口。
方式二，系统应用可以通过系统提供的配置入口，将上面的删除数据入口，改成提示界面，如图13所示，系统原有的“删除数据”文字被替换成“管理空间”，或者其他提示文字都可以。如果用户点击该按钮，可以弹窗提示用户，该数据不能删除。图13为本申请一个实施例提供的将删除数据入口改成提示界面的示意图。
图14为本申请另一个实施例提供的图片的存储方法的流程图，如图14所示，本申请图11所示实施例中，步骤1106之后，还可以包括：
步骤1401，检测到用户解锁目标相册的第二触发操作。
步骤1402，响应于上述第二触发操作，获取用户输入的解锁信息。
其中，上述解锁信息可以为用户对目标相册添加相册锁时设置的密码，也可以为用户对目 标相册添加相册锁时关联的生物识别信息，例如：人脸识别或指纹识别等，本实施例对上述解锁信息的具体形式不作限定。
具体地，以目标相册为隐藏相册为例，用户在访问加锁的目标相册时，终端设备100首先显示图15(a)所示的界面，图15(a)所示的界面中显示“隐藏相册已锁定”的提示信息，这时用户可以点击图15(a)所示界面中的“解锁”图标，用户点击“解锁”图标的操作即为第二触发操作，检测到用户解锁目标相册的第二触发操作之后，终端设备100可以显示图15(b)所示界面，然后用户可以在图15(b)所示的界面中输入解锁信息，终端设备100获取用户输入的解锁信息，图15(b)中，解锁信息为密码。图15(a)～图15(b)为本申请一个实施例提供的解锁目标相册的界面示意图。
步骤1403，确定上述解锁信息通过安全校验之后，根据目标相册的标识，获取上述目标相册包括的图片名称。
步骤1404，将待查看的图片名称，通过文件打开接口传递给系统应用。
步骤1405，在系统应用根据上述待查看的图片名称，打开待查看的图片文件之后，获取系统应用返回的待查看的图片文件的第二文件描述符。
具体地，系统应用接收到待查看的图片名称之后，可以根据上述待查看的图片名称，找到对应的图片文件，进而打开待查看的图片文件，向图库返回待查看的图片文件的第二文件描述符。
步骤1406，根据第二文件描述符，通过图库读取并显示上述待查看的图片内容。
具体地，图库拿到第二文件描述符之后，可以根据上述第二文件描述符读取图片内容，进行显示。
对于目标相册中图片的修改，可以分为两种：
1)对图片内容的修改，比如进入编辑模式，进行涂鸦或打上水印；
2)对图片文件信息的修改，比如修改文件名称。
其中，对图片内容的修改，与访问图片一样，图库根据收到的第二文件描述符，修改系统应用的图片内容即可，如图16所示，图16为本申请再一个实施例提供的图片的存储方法的流程图，本申请图14所示实施例中，步骤1403之后，还可以包括：
步骤1601，将待修改图片内容的图片名称，通过文件打开接口传递给系统应用。
步骤1602，在系统应用根据上述待修改图片内容的图片名称，打开待修改图片内容的图片文件之后，获取系统应用返回的待修改图片内容的图片文件的第三文件描述符。
步骤1603，根据上述第三文件描述符，通过图库读取并显示待修改的图片内容。
步骤1604，通过图库对上述待修改的图片内容进行修改。
步骤1605，通过图库根据第三文件描述符，将修改后的图片内容保存到第二内部存储区。
对图片信息的修改，比如修改文件名称，这个就不用通过文件描述符来操作。可以在相册锁对应的系统应用侧增加一个进程间通信接口，用于修改图片文件信息。图库调用该接口，将修改的图片信息发送给系统应用侧，系统应用根据图片名称找到图片，并替换信息，完成文件信息修改，如图17所示，图17为本申请再一个实施例提供的图片的存储方法的流程图，本申请图14所示实施例中，步骤1403之后，还可以包括：
步骤1701，通过图库获取待修改图片文件信息的图片名称。
步骤1702，通过图库对上述待修改图片文件信息进行修改。
步骤1703，通过图库与上述系统应用之间的图片信息修改接口，将上述待修改图片文件信息的图片名称和修改后的图片文件信息传递给系统应用，以供系统应用查找到上述待修改图片文件信息的图片名称对应的图片文件之后，将查找到的图片文件的文件信息替换为上述修改后的图片文件信息。
本申请实施例中，用户可以在相册浏览界面，删除加锁相册中的图片。终端设备100在图 库的相册浏览界面上，提供多选交互界面，用户可以通过多选交互界面选择图片，之后点击删除并确认，即可触发删除行为。系统应用提供删除接口，图库调用该接口，将用户选择删除的图片的名称发送给系统应用。系统应用根据图片名称，直接删除图片文件，如图18所示，图18为本申请再一个实施例提供的图片的存储方法的流程图，本申请图14所示实施例中，步骤1403之后，还可以包括：
步骤1801，通过图库获取待删除的图片名称。
步骤1802，通过图库与上述系统应用之间的图片删除接口，将待删除的图片名称传递给上述系统应用，以供系统应用删除上述待删除的图片名称对应的图片文件。
本申请实施例中，参见图19，用户访问加锁相册，完成浏览、图片保存和/或图片修改等操作之后，可以点击返回按钮1901离开加锁相册。或者，用户可以点击加锁按钮1902，返回到加锁界面。图19为本申请一个实施例提供的关闭和打开相册锁的界面示意图。
本申请实施例中，用户可以在加锁相册打开之后，移除相册锁，将该相册恢复成一个普通相册。移除的时候，通过小弹窗提示。相册锁移除之后，导航栏锁相关菜单全部消失不可见。也就是说，如图20所示，本申请图11所示实施例中，步骤1102之后，终端设备100还可以在检测到用户移除上述目标相册的相册锁的第三触发操作之后，响应于上述第三触发操作，获取用户输入的解锁信息，确定上述解锁信息通过安全校验之后，为上述目标相册移除相册锁。图20为本申请一个实施例提供的移除相册锁的界面示意图。
本申请实施例在图库的相册界面提供加锁菜单，用户点击加锁菜单之后，终端设备100对当前相册执行加锁操作。
首先，提示用户输入密码，并完成两次输入校验。同时可以根据终端设备100的硬件情况，提示用户可以关联指纹识别，或者关联人脸识别。
之后图库将当前相册的照片，转存入相册锁对应的系统应用的内部存储区。该系统应用由于无法卸载，用户无法通过卸载按钮清除其内部存储区的数据。同时该系统应用又对系统清理存储区入口进行屏蔽，用户无法通过点击清理存储区，来清空上述系统应用的数据。
通过以上操作，终端设备100可以通过图库将加锁相册中的图片转存入一个安全位置。用户能且只能通过图库的加锁相册入口、访问、修改和/或删除加锁相册的图片。
另外，本申请实施例提供的图片的存储方法可以对任意相册进行加锁，同时本申请实施例没有使用加解密算法，不需要通过对图片进行加解密来保障图片的信息安全。这样，对设备来说就不需要进行大量运算来对图片进行加解密，在减少终端设备100开销的同时也减少了用户访问图片需要的时间；对图片来说，不需要担心加解密算法被破解导致信息泄露问题；同时也不用担心用户虽然看不到图片，但是可以删除图片，导致信息丢失的问题。
同时本申请实施例又能屏蔽用户通过卸载更新来清除数据的方式，同时也屏蔽了用户直接清理存储区的入口，保证用户能且只能通过加锁相册入口访问图片。
另外，本申请实施例提供的方法也可以作用于其他任意应用，除了可以用来存储加锁相册，还可以用来存储保密柜数据或者存储任意应用的隐私数据。
可以理解的是，上述实施例中的部分或全部步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
可以理解的是，终端设备为了实现上述功能，其包含了执行各个功能相应的硬件和/或软件模块。结合本申请所公开的实施例描述的各示例的算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以结合实施例对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本实施例可以根据上述方法实施例对终端设备进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个模块中。上述集成的模块可以采用硬件的形式实现。需要说明的是，本实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
图21为本申请另一个实施例提供的终端设备的结构示意图，在采用对应各个功能划分各个功能模块的情况下，图21示出了上述实施例中涉及的终端设备2100的一种可能的组成示意图，如图21所示，该终端设备2100可以包括：检测模块2101、添加模块2102、启动模块2103、传输模块2104、获取模块2105和保存模块2106；
