Description

一种照片共享方法及电子设备 技术领域
本申请涉及终端技术领域，尤其涉及一种照片共享方法及电子设备。
背景技术
随着数据大规模增长和数据价值的日益提升，通过数据共享的方式来挖掘数据的潜在价值变得越来越重要，但如何在数据共享的同时，保护敏感数据、涉密数据等不被非法窃取，是数据共享的重要前提。
目前的数据共享方法，主要包括传统数据共享方案和中心化数据共享方案。其中，传统数据共享方案是使用传统的隐私保护手段实现内部共享，同时为降低暴露隐私数据的风险选择拒绝对外开放共享权限；中心化数据共享方案是以第三方作为数据开放和共享的中枢，各数据拥有者对第三方信任并对第三方开放数据，通过第三方调度来实现数据共享过程。
但是，现有的传统数据共享方案的缺点是，以拒绝对外开放来降低隐私风险，不仅无法挖掘数据的潜在价值，不能最大化其利益，且会导致信息建设滞后；中心化数据共享方案虽然解决了互不信任的问题，但却由于数据集中在第三方，所以存有安全隐患，即如果第三方无法保证绝对数据安全，一旦发生数据泄漏会造成严重后果。
发明内容
本申请提供一种照片共享方法及电子设备，用以提供一种安全有效的照片共享方式，以充分挖掘数据的潜在价值，提高用户体验。
第一方面，本申请实施例提供一种照片共享方法，所述方法适用于第一电子设备，该方法包括：当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第一操作；响应于该第一操作，第一电子设备在第一电子设备的第一共享相簿中添加第一照片信息。然后当第一电子设备与第二电子设备发起同步时，向第二电子设备发送添加第一照片信息的第一请求消息。这样当第一电子设备接收所述第二电子设备发送的拒绝添加所述第一照片信息的第一请求响应消息后，就将第一共享相簿中的第一照片信息删掉。
该方法可以实现去中心化数据共享，电子设备之间可以共享对方共享相簿中的照片。
在一种可能的设计中，在第一电子设备将所述第一共享相簿中的所述第一照片信息删除之后，该照片共享方法还包括：第一电子设备将第二电子设备中的第四共享相簿的照片信息同步至所述第一电子设备。其中，第四共享相簿包括第一共享相簿的照片信息、第二电子设备的第二共享相簿的照片信息和第三电子设备的第三共享相簿的照片信息；第一共享相簿的照片信息不包括第一照片信息。
本申请实施例中，第一电子设备可以将第四共享相簿中的照片信息同步到本地，所以可以实现共享其它电子设备的照片信息，第二电子设备可以保证第一共享相簿对应的区块链的有序增长。
在一种可能的设计中，在检测到用户的第一操作之前，当第一电子设备与第二电子设 备未发起同步时，第一电子设备检测到用户的第二操作；响应于该第二操作，在第一共享相簿中添加第二照片信息，当第一电子设备与第二电子设备发起同步时，第一电子设备向所述第二电子设备发送添加第二照片信息的第二请求消息。接着，第一电子设备接收所述第二电子设备发送的添加成功所述第二照片信息的第二请求响应消息。这样第一电子设备的第一共享薄中的第二照片信息添加成功。
仍然是在检测到用户的第一操作之前，当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第三操作；响应于该第三操作，在包括所述第二照片信息的第一共享相簿中添加第三照片信息；当第一电子设备与第二电子设备发起同步时，第一电子设备向所述第二电子设备发送添加所述第三照片信息的第三请求消息，接着，第一电子设备接收所述第二电子设备发送的添加成功所述第三照片信息的第三请求响应消息。这样第一电子设备的第一共享薄中的第三照片信息添加成功。结合本申请实施例提供的区块链技术来说，第一电子设备和所述第二电子设备、第三电子设备为区块链网络中的设备；第二电子设备相当于是区块链网络的中心节点，而第一电子设备和第三电子设备则相当于区块链网络的普通节点。
其中，照片信息可以以记录的形式添加到共享相簿中，例如第二照片信息对应第一记录包括第一标识、所述第二照片的哈希值和所述第二照片的内容数据；第三照片信息对应的第二记录包括第二标识、第二照片的哈希值和第三照片的内容数据，以及第一标识。也就是说第二记录是与第一记录相关联的。
可见，本申请实施例中，共享相簿中的照片信息本质是区块链，因区块链具有去中心化、数据高度透明、无须依赖信任以及信息可回溯性的特点，所以本申请实施例生成的共享相簿相比现有数据共享方式，具有显著的去中心化，信息可回溯等优点。
在一种可能的设计中，当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第四操作；响应于第四操作，第一电子设备将第一共享相簿中的第三照片信息删除。当第一电子设备与第二电子设备发起同步时，第一电子设备向第二电子设备发送删除第三照片信息的第四请求消息；第一电子设备接收第二电子设备发送的删除成功第三照片信息的第四请求响应消息。
本申请实施例中，第一电子设备可以请求第二电子设备删除共享相簿中的照片，因此第二电子设备可以保证第四共享相簿对应的区块链的有序增长，能够有效地避免各个电子设备增删照片的冲突行为。
第二方面，本申请实施例提供一种照片共享方法，该方法应用于第二电子设备，该方法包括：第二电子设备建立与第一电子设备的网络连接，然后第二电子设备接收第一电子设备发送的添加第一照片信息的第一请求消息。响应于该第一请求消息，第二电子设备向第一电子设备发送拒绝添加第一照片信息的第一请求响应消息。
该方法可以实现去中心化数据共享，电子设备之间可以共享对方共享相簿中的照片，第二电子设备可以保证共享相簿对应的区块链的有序增长。其中，第二电子设备的具体执行步骤与第一电子设备相对应，所以具体内容可以参见上文介绍，本实施例中不再重复赘述。
第三方面，本申请实施例提供一种第一电子设备，包括处理器和存储器。其中，存储器用于存储一个或多个计算机程序；当存储器存储的一个或多个计算机程序被处理器执行时，使得第一电子设备能够实现第一方面的任意一种可能的设计的方法。
第四方面，本申请实施例还提供一种装置，该装置包括执行第一方面或者第一方面的任意一种可能的设计的方法的模块/单元。这些模块/单元可以通过硬件实现，也可以通过硬件执行相应的软件实现。
第五方面，本申请实施例中还提供一种计算机可读存储介质，所述计算机可读存储介质包括计算机程序，当计算机程序在电子设备上运行时，使得所述电子设备执行第一方面或上述第一方面的任意一种可能的设计的方法。
第六方面，本申请实施例还提供一种包含计算机程序产品，当所述计算机程序产品在终端上运行时，使得所述电子设备执行第一方面或上述第一方面的任意一种可能的设计的方法。
本申请的这些方面或其他方面在以下实施例的描述中会更加简明易懂。

以下实施例均可以在具有上述硬件结构的电子设备01(例如电子设备100、平板电脑等)中实现。以下实施例将以电子设备100是移动终端为例，对本申请实施例提供的数据共享方法进行说明。
首先，本申请实施例提供一种新的区块链技术，该区块链技术提出公有区块链和私有区块链的概念，所谓公有区块链指的是区块链网络中的所有节点对应的区块链，所谓私有区块链指的是每个节点对应的区块链。举例来说，该新的区块链技术中的节点组成的区块链网络如图4a所示，其中节点2为中心节点，中心节点用于保证公有区块链中的区块可以有序增长，避免出现冲突；节点1和节点3为普通节点，节点1、节点2、节点3均设有一个私有区块链。如图4b所示，节点1的私有区块链上包括子区块11、子区块12，节点2的私有区块链上包括子区块21、子区块22，节点3的私有区块链上包括子区块31、子区块32。当各个私有区块链上的子区块均被节点2确认为合法的子区块时，则当前节点1、节点2和节点3构成的区块链网络对应的公有区块链如图4c所示，该公有区块链包括主区块01、主区块02，其中主区块01包括子区块11、子区块21和子区块31，主区块02包括子区块12、子区块22和子区块32。
需要说明的是，虽然现有的区块链技术也有中心节点，普通节点生成区块的行为也需要得到中心节点的认可，当中心节点确认生成区块的行为合法之后，会在公有区块链上顺序增长该合法的区块，但是现有的区块链网络仅有公有区块链，中心节点必须始终在线，才能对普通节点生成区块的行为进行实时认证，如果中心节点离线，公有区块链就不能按顺序增长。这样的话，当现有区块链技术应用到移动终端时就会暴露出缺陷，因移动终端的电池电量是有限的，所以移动终端无法保证始终在线，也就是说无法始终与其它节点建立网络连接。
与现有的区块链技术相比，本申请实施例提供的区块链技术通过增加私有区块链，可以有效地解决移动终端无法始终在线的问题。举例来说，节点1、节点2、节点3无论是否接入网络，都可以随时在自身的私有区块链上增长子区块，如图4d所示，假设节点1在离线时，在自身的私有区块链上增长了子区块13；节点3在离线时，在自身的私有区块链上增长子区块33、子区块34。当节点1、节点3再次接入到网络时，会向节点2提交请求，请求节点2在公有区块链上增长区块03，该区块03包括子区块13、子区块33、子区块34。如果节点2认证子区块13、子区块33、子区块34合法后，节点2在公有区块链上增长区块03，该区块03包括子区块13、子区块33、子区块34。然后，节点1和节点3再从节点2获取增长后的公有区块链，该公有区块链如图4e所示。
另外，当节点1、节点3向节点2提交请求，请求在公有区块链上增长区块03，该区块03包括子区块13、子区块33、子区块34，如果节点2认证子区块13、子区块33合法，但子区块34不合法，则节点2向节点3发送通知，该通知包括子区块34不合法，不能增长到公有区块链中。节点3收到该通知之后，会选择在子区块33之后顺序增长下一个子区块35，即子区块34被丢弃。节点2在公有区块链上增长区块03，该区块03包括子区块13、子区块33。然后，节点1和节点3再从节点2获取增长后的公有区块链，该公有区块链如图4f所示。
从上述内容可见，本申请实施例提供的区块链技术中，中心节点可以在接入网络时，对普通节点提交的增长区块的行为进行认证，只有中心节点认证通过后才会在公有区块链上增加新的区块，所以中心节点可以保证公有区块链的顺序增长，有效的避免增长区块的冲突行为。另外，每个节点都设有私有区块链，每个节点可以在在线或者离线状态下，实时地在自身的私有区块链上提交增长子区块的行为，一旦接入网络时，再将该增加子区块的行为发送到中心节点认证，所以可以有效地解决移动终端不在线无法增加区块的问题。另一方面，每个节点均存储有公有区块链，相当于分布式数据库，即便单个节点发生故障，仍然可以从其它节点恢复出公有区块链，所以可以有效地保证数据安全性。
基于上述区块链技术，本申请实施例提供一种数据共享方案，该方案可以实现在多个电子设备之间共享数据。具体地，通过上述区块链技术，可以建立包括多个电子设备的群组，该群组中每个电子设备可以共享其它电子设备中的数据。其中，共享数据可以指电子设备中的图片、视频或交易数据、健康数据等信息。相比现有的中心化数据共享方案，本申请实施例提供的共享数据方案既能够保证群组中的数据共享性，也能保证群组中的数据安全性。
以下将结合附图和应用场景，对本申请实施例提供的数据共享方案进行详细介绍。
以下将以共享的数据为电子设备中的图片为例，对本申请实施例提供的数据共享方法 进行说明。该图片可以是电子设备拍摄的一张图片，也可以是电子设备中保存的一张图片，还可以是电子设备从其他设备接收到的一张图片。

示例性的，方式二，参见图9，当电子设备2检测到用户2作用于图8c中搜索附近503这一选项的操作(例如点击)时，响应于该操作，电子设备2搜索附近的电子设备，例如图9a中显示搜索到设备名称为huaweiP20的电子设备1，当用户点击头像后可以加入设备名称为huaweiP20的电子设备1创建的“家庭照片”这一亲情空间。需要说明的是，电子设备2扫搜附近的电子设备的方式可以但不限于蓝牙、wifi热点、wifi直连或NFC等近距离网络连接方式。示例性地，如图9b所示，用户2可以进入设置菜单打开wifi热点这一网 络类型，通过wifi热点搜索附近的电子设备。除此之外，用户2也可以通过通知栏的快捷功能控件选择打开wifi热点这一网络类型。
第二种场景，如图10所示，当用户1创建了“家庭照片”这一群组后，电子设备1检测到用户1作用于图10a中邀请或加入600这一选项的操作(例如点击)时，响应于该操作，电子设备1显示图10b所示的界面，该界面中包括两个选项：我要加入601和我要邀请602。可参考图10c，当电子设备1检测到用户1作用于图10b中我要邀请602这一选项的操作(例如点击)时，响应于该操作，电子设备1显示图6c所示的界面，该界面显示有搜索附近603和空间二维码604这两个选项。方式一，当电子设备1检测到用户1作用于图10c中空间二维码604这一选项的操作(例如点击)时，响应于该操作，显示有“家庭照片”这一空间的二维码。方式二，当电子设备1检测到用户1作用于图10c中搜索附近603这一选项的操作(例如点击)时，响s应于该操作，电子设备1搜索到设备名称为huaweiP10的电子设备2，如图10d所示，当电子设备1检测到用户1作用于图10d中的头像的操作(例如点击)时，响应于该操作，电子设备1显示图10e所示的界面，图10e中显示有电子设备1所创建的“家庭照片”这一空间，当电子设备1检测到用户1的确认操作后，设备名称为huaweiP10的电子设备2被邀请到家庭照片”这一空间。
第三种场景，当用户2加入到“家庭照片”这一群组后，示例性的，参见图11，当电子设备2检测到用户2作用于图11a中相册这一选项的操作(例如点击)时，响应于该操作，电子设备2显示相册这一应用中的图片，如图11b所示。当用户选中图11b中的第二图片702、第三图片703、第四图片704之后，响应于用户2作用于图11b中上传选项的操作(例如点击)，电子设备2生成关于第二图片702、第三图片703、第四图片704的哈希值(hash)和缩略图，然后将该哈希值和缩略图上传到“家庭照片”这一空间。参见图11c所示，电子设备2显示用户上传的关于第二图片702、第三图片703、第四图片704的缩略图。其中，电子设备2上传的信息需要得到“家庭照片”这一空间的创建者(即电子设备1)的认证。也就是说，电子设备1相当于是中心节点，当电子设备1在线且对电子设备2上传的信息认证通过后，电子设备2上传的信息才能够真正上传到“家庭照片”这一空间中。
在一种可能的设计中，如图11c所示，当电子设备2上传第二图片702、第三图片703、第四图片704后，电子设备2中关于第二图片702、第三图片703、第四图片704的缩略图上添加有第一标识，第一标识上标记图片当前属于待认证的状态，即第二图片702、第三图片703、第四图片704尚未被电子设备1认证通过。如果电子设备1接入网后，收到来自电子设备2的请求上传关于第二图片702、第三图片703、第四图片704的哈希值和缩略图的信息，则电子设备2对该请求信息进行认证，若认证通过，则该信息被上传到该空间中，如图11d所示，电子设备2和电子设备1上均显示当前“家庭照片”空间有两个成员(小美和小明)，其中小美是电子设备1的用户1的昵称，小明是电子设备2的用户2的昵称，小美这一成员中有一张图片信息，小明这一成员中有三张图片信息。当电子设备1检测到用户作用于图11d中小明这一选项706的操作(例如点击)时，响应于该操作，电子设备1显示如图11e所述的界面，该界面中显示电子设备2的用户2(小明)在2018年7月12日上传到该空间的三张图片的缩略图。当电子设备1检测到用户作用于图11e中第二图片的缩略图707的操作(例如点击)时，响应于该操作，电子设备1根据该第二图片的哈希值从电子设备2上获取该第二图片的原图数据，然后显示在如图11f所示的界面。其中，电子设备1之所以能够从电子设备2上获取第二图片的原图数据，是因为电子 设备1和电子设备2之间建立了近距离网络连接，或者是因为电子设备1和电子设备2打开数据流量开关，电子设备1和电子设备2之间建立了数据网络连接。
在一种可能的设计中，如图12所示，如果电子设备1对电子设备2所上传的信息进行认证，可能因第三图片的数据量过大，最后生成的认证结果包括第三图片认证失败，第二图片和第四图片认证成功，如图12a所示，电子设备2中自身的成员信息中显示有第三图片的第二标识为认证失败的状态。参见图12b所示，同步更新之后，电子设备2和电子设备1上均显示当前“家庭照片”空间有两个成员(小美和小明)，其小美这一成员中有一张图片信息，小明这一成员中有两张图片信息，其中，小明这一成员的图片信息中不包括认证失败的的第三图片，仅包括第二图片和第四图片。
需要说明的是，电子设备1对第三照片认证失败原因还可能是因网络不稳定，导致电子设备1未收到电子设备2发送的认证请求，或者是电子设备1认为第三照片不符合共享条件(例如不雅照等)。也可能是电子设备1为每个成员的相簿设置了容量大小，若电子设备1判断若添加第三照片会导致超出电子设备2的最大容量，则对电子设备2认证失败。
在一种可能的设计中，如图13所示，如果电子设备2检测到用户2作用于图13a中801这一选项的操作(例如点击)时，响应于该操作，电子设备2显示图13b所示的界面，图13b中显示用户2在2018年7月5日上传了第二图片，在2017年7月12日上传了第三图片和第四图片。当电子设备2检测到用户2作用于图13b中的第二图片的缩略图802这一选项的操作(例如点击)时，响应于该操作，电子设备2从自身数据库中获取第二图片的原图数据信息，并显示图13c所示的界面。如果电子设备2检测到用户2作用于图13c中删除这一控件803的操作(例如点击)时，响应于该操作，电子设备2的第二图片的缩略图802从“家庭照片”这一空间移除，最后电子设备1和电子设备2显示如图13d所示的界面，即“家庭照片”这一空间中有两个成员，其中小明上传的图片数量变更为2。
需要说明的是，上述图13d中显示的“家庭照片”是按照成员信息进行照片分类，除此之外，“家庭照片”还可以支持按照照片的拍摄地点、拍摄时间、或者按照人物类型、风景类型对空间中的照片进行分类显示，本申请实施例不再一一列举图例说明。
在一种可能的设计中，如图14所示，如果电子设备1检测到用户1作用于图14a中901这一选项的操作(例如点击)时，响应于该操作，电子设备1显示显示图14b所示的界面，图14b中显示用户2在2018年7月5日上传了第二图片，在2017年7月12日上传了第三图片和第四图片。当电子设备1检测到用户1作用于图14b中的第二图片的缩略图902这一选项的操作(例如点击)时，响应于该操作，电子设备1根据该缩略图902对应的哈希值，从电子设备2中获取第二图片的原图数据信息，并显示图14c所示的界面。如果电子设备1检测到用户1作用于图14c中删除这一控件903的操作(例如点击)时，响应于该操作，电子设备1的第二图片的缩略图902从“家庭照片”这一空间移除，电子设备2显示如图14d所示的界面，即小明这一成员的缩略图仅有两个。但是，电子设备1显示如图14a所示的界面。当后续电子设备1同步“家庭照片”这一空间的所有成员的数据后，电子设备1恢复至如图14a所示的界面。也就是说，电子设备1只能临时删除群组中的其它成功的缩略图，而且后期一旦同步数据，还可以恢复该被删除的缩略图。
补充来说，电子设备2也可以将在空间中上传的图片的原图备份到云端，当电子设备1检测到用户1作用于缩略图902的操作时，则电子设备1从云端获取该缩略图902对应的原图数据，从而显示该原图在如图14a所示的界面。
需要说明的是，在一种可能的实现中，当电子设备1检测到用户1作用于图14b中的第二图片的缩略图902这一选项的操作(例如点击)时，响应于该操作，电子设备1根据该缩略图902对应的哈希值，从云端服务器获取第二图片的原图数据信息，并显示图14c所示的界面。
在本申请实施例中，亲情空间还提供一种美好时光功能，该功能能够可以实现对各个成员中的图片进行编辑处理。如图15所示，示例性地，当电子设备1检测到用户1作用于图15a的美好时光这一控件的操作时，电子设备1显示图15b所示的界面，在图15b中，小美这一成员中的图片可以被编辑成视频，小明这一成员中的图片也可以被编辑成视频。另外，“家庭照片”这一空间还可以设置有评论或者点赞等功能，例如当电子设备1的用户1查看“家庭照片”中的其它成员的照片时，可以对该照片进行评论或者点赞。在一种可能的设计中，“家庭照片”这一空间还可以设置有分享功能，例如当电子设备1的用户1查看“家庭照片”中的其它成员的第一照片时，可以选择分享该第一照片至“家庭照片”群组之外的成员。打比方说，电子设备1检测到用户1作用于分享这一控件的操作时，生成关于第一照片的链接，电子设备1通过发送该链接至另一成员，完成分享。
以上是以共享数据为图片为例进行说明的，共享数据也可以为电子设备中的淘宝订单信息、文本信息、视频或文件夹、健康数据、运动数据等。与共享数据为图片的数据共享方法类似，当共享数据为淘宝订单信息、文本信息、视频或文件夹、健康数据、运动数据等时，可以采用上述“家庭照片”共享方式进行数据共享。
示例性地，在本申请另一实施例中，当共享数据是运动数据时，亲情空间还可以包括共享运动数据的群组，群组中的各成员的运动数据可以被其它成员共享。其中，共享运动数据的群组的建立过程，以及群成员加入或者邀请加入的过程可以参考上文建立“家庭照片”空间的过程。举例来说，电子设备1和电子设备2响应于用户1和用户2作用于运动手环APP的操作，将运动手环APP的数据查看权限授权给亲情空间，即运动手环APP与亲情空间账号建立绑定关系。如图16所示，当电子设备1检测到用户1作用于图16a所示的亲情空间的运动图标1001的操作(例如点击)时，响应于该操作，电子设备1显示图16b所示的界面，该界面显示当前有运动成员小美和小明。当电子设备1检测到用户1作用于图16b所示的小美的图像操作(例如点击)时，电子设备1显示从运动手环APP获取的用户1的运动数据，包括行走步数、睡眠时间、心率、体重等数据。电子设备1的图16b所示的界面还提供备份运动数据到云端的选项，当用户1作用于该选项将运动数据上传到云端，则用户1下次查看运动数据，电子设备1可以从云端获取该运动数据。当然，电子设备1也可以将运动数据保存在本地，这样电子设备1可以在离线状态下随时从存储空间获取运动数据，但是会占用本地的存储空间。
在本申请其它实施例中，当共享数据是健康数据时，亲情空间还可以包括健康数据的群组，群组中的各成员的健康数据可以被其它成员共享。其中，共享健康数据的群组的建立过程，以及群成员加入或者邀请加入的过程可以参考上文建立“家庭照片”空间的过程。如图17所示，举例来说，当电子设备1检测到用户1作用于图17a所示的亲情空间的健康记录1101的操作(例如点击)时，响应于该操作，电子设备1显示图17b所示的界面，该界面显示当前有家庭成员小美和小明。当电子设备1检测到用户1作用于图17b所示的小美的图像操作(例如点击)时，电子设备1显示图17c所示的界面。电子设备1检测到用户1上传的病例图片后，可以从该病例图片信息中自动获取医院、科室、就诊时间等信息， 电子设备1的图17c所示的界面中还提供备份病例到云端的选项，当用户1作用于该选项将病例上传到云端，则用户1下次查看该病例，电子设备1可以从云端获取该病例。当然，电子设备1也可以将病例保存在本地，这样电子设备1可以在离线状态下随时从存储空间获取病例数据，但是会占用本地的存储空间。
在一种可能的设计中，如图18所示，当电子设备1检测到用户1作用于图18a所示的亲情空间1201的操作(例如点击)时，响应于该操作，电子设备1显示图18b所示的列表，列表中显示有电子设备1的用户1在“家庭空间”中的昵称、性别、生日、数据流程模式、意见反馈。检查更新、清理缓存等信息。其中，当电子设备1检测到用户1作用于图18b所示的数据流程模式1202的操作(例如点击)时，响应于该操作，电子设备1打开或关闭数据流量开关，当电子设备1打开数据流量开关时，则同步该“家庭空间”其它成员的图片信息。当然，当电子设备1关闭数据流量开关，但打开WiFi热点时，也可以同步接入到该WiFi热点的其它成员的图片信息。
在一种情况下，在“家庭照片”这一空间中电子设备1可以相当于是区块链网络的中心节点，其它成员则相当于是区块链网络的普通节点。如果电子设备2接入网络，但是电子设备1没有接入网络时，则电子设备2无法从电子设备1获取“家庭照片”所有成员的图片信息，则电子设备2无法同步更新其它成员的图片信息。
结合本申请实施例提供的区块链技术来说，可见上述场景中“家庭照片”这一空间的创建者相当于区块链网络的中心节点，而其它成员则相当于区块链网络的普通节点。例如电子设备1相当于图4a中的节点2，电子设备2相当于图4a中的节点1或节点3。其中，“家庭照片”这一空间下面的小美的图片信息相当于电子设备1的私有区块链，“家庭照片”这一空间下面的小明的图片信息相当于电子设备2的私有区块链。最终，电子设备1和电子设备2同步数据后会生成具有相同图片信息的“家庭照片”空间，这一空间相当于公有区块链。各个电子设备每次上传的数据构成该电子设备对应的私有区块链中的一个子区块，电子设备1每次认证成功，所认证通过的所有数据构成公有区块链的主区块。
换句话说，电子设备1和电子设备2可以在离线状态下，上传照片到自身的私有区块链中，当电子设备2接入网络时，可以将向电子设备1发送认证请求，请求认证在离线状态下上传的图片，若电子设备1认证通过，则电子设备2上传的图片信息被同步到公有区块链中，最终电子设备1上的“家庭空间”中也包括电子设备2上传的该图片。所以说，群组的各个成员，可以随时随地地分享图片，并记录到图片信息到自身的私有区块链中，并不需要电子设备1(中心节点)始终在线或及时响应才能分享图片。对于各个电子设备来说，当认证失败时，也只需要回退到最后一个认证成功的区块，例如回退到最后一次上传成功的状态。
在另一种情况下，在“家庭照片”这一空间中电子设备1和电子设备2可以相当于是普通节点，电子设备1和电子设备2可以在离线或在线状态下，生成上传照片的哈希值和缩略图，并在自身的私有区块链新增子区块，该子区块信息中保存有该哈希值和缩略图，以及该哈希值和缩略图与上传图片之间的对应关系。其中，云服务器可以与电子设备1和电子设备2建立网络连接，当云服务器与电子设备1之间建立网络连接时，电子设备1将自身的私有区块链的新增的子区块信息上报至云服务器侧，云服务器侧对该子区块认证通过后，将该子区块信息保存至公有区块链新增的主区块中。同样的，当云服务器与电子设备2之间建立网络连接时，电子设备2将自身的私有区块链的新增的子区块信息上报至云服 务器侧，云服务器侧对该子区块认证通过后，将该子区块信息保存至公有区块链新增的主区块中。
本申请实施例进一步提供了一种照片共享方法，如图19所示，该方法可以包括以下步骤：
1901、当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第一操作。
1902、第一电子设备响应于该第一操作，在第一电子设备的第一共享相簿中添加第一照片信息。
其中，第一共享相簿包括所述第一电子设备添加的照片信息。
1903、第一电子设备当所述第一电子设备与所述第二电子设备发起同步时，向第二电子设备发送添加所述第一照片信息的第一请求消息。
1904、第一电子设备接收所述第二电子设备发送的拒绝添加所述第一照片信息的第一请求响应消息。
1905、第一电子设备将所述第一共享相簿中的所述第一照片信息删除。
结合上述场景图11和图12来说，第一电子设备相当于图中的电子设备2，第二电子设备相当于图中的电子设备1。另外，第一照片信息可以直接指第一照片，也可以指与第一照片对应的索引信息，例如链接信息或与第一照片的缩略图等。结合图12来说，第一照片信息相当于图12中的第三照片。
当电子设备2与电子设备1未发起同步时，电子设备2向“家庭照片”里面用于存储电子设备2的用户小明的照片信息的相簿(即第一共享相簿)上传第三照片。所谓未发起同步可以指电子设备2没有与电子设备1建立网络连接，也可能指电子设备2与电子设备1建立了网络连接，电子设备2当前处于不与电子设备1进行同步的时段。
当电子设备2与电子设备1发起同步时，电子设备1可以接收到电子设备2发送第三照片的认证请求，该认证请求相当于步骤1903中的添加所述第一照片信息的第一请求消息，当电子设备1确定第三照片的数据量过大，对第三照片认证失败未添加第三照片到“家庭照片”时，电子设备1向电子设备2发送第一请求响应消息，即通知电子设备2第三照片为认证失败的状态，拒绝添加第三照片。这样电子设备2就将第三照片从第一共享相簿中删除，如图12b所示，小明的相簿中仅有两个照片信息。
在一种可能的实施例中，在第一电子设备将所述第一共享相簿中的所述第一照片信息删除之后，该照片共享方法还包括：第一电子设备将第二电子设备中的第四共享相簿的照片信息同步至所述第一电子设备。其中，第四共享相簿包括所述第一共享相簿的照片信息、第二电子设备的第二共享相簿的照片信息和第三电子设备的第三共享相簿的照片信息；第一共享相簿的照片信息不包括第一照片信息。
结合图20来说，假设“家庭照片”这一空间中又新增一个成员电子设备3，其中电子设备3的用户昵称为小王，且小王在空间中自身的相簿中添加成功一张照片。那么当电子设备2同步电子设备1的“家庭照片”之后，电子设备2中“家庭照片”包括电子设备1的照片、电子设备2的照片和电子设备3的照片。也就是说，第四共享相簿相当于图20中的“家庭照片”这一空间，第二共享相簿相当于用于存储电子设备1的用户小美的照片信息的相簿。第三共享相簿相当于用于存储电子设备3的用户小王的照片信息的相簿。从图20中可见， 同步之后，电子设备2小明的相簿中不包括认证失败的第三照片。
进一步地，在一种可能的实施例中，在检测到用户的第一操作之前，当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第二操作；响应于该第二操作，在第一共享相簿中添加第二照片信息，当第一电子设备与第二电子设备发起同步时，第一电子设备向所述第二电子设备发送添加第二照片信息的第二请求消息。接着，第一电子设备接收所述第二电子设备发送的添加成功所述第二照片信息的第二请求响应消息。这样第一电子设备的第一共享薄中的第二照片信息添加成功。
仍然是在检测到用户的第一操作之前，当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第三操作；响应于该第三操作，在包括所述第二照片信息的第一共享相簿中添加第三照片信息；当第一电子设备与第二电子设备发起同步时，第一电子设备向所述第二电子设备发送添加所述第三照片信息的第三请求消息，接着，第一电子设备接收所述第二电子设备发送的添加成功所述第三照片信息的第三请求响应消息。这样第一电子设备的第一共享薄中的第三照片信息添加成功。
参见图21来说，电子设备2检测到用户2作用于相册中的照片2101的操作，参见图21a和图21b所示，向电子设备1发送添加照片2101至“家庭照片”空间的请求消息，当电子设备1添加照片成功后，电子设备2对应的小明的共享相簿显示有一张照片，参见图21c所示。接着，电子设备2检测到用户2作用于相册中的照片2102的操作，参见图21d和图21e所示，向电子设备1发送添加照片2102至“家庭照片”空间的请求消息，当电子设备1添加照片成功后，电子设备2对应的小明的共享相簿显示有两张照片，参见图21f所示。
结合本申请实施例提供的区块链技术来说，第一电子设备和所述第二电子设备、第三电子设备为区块链网络中的设备；第二电子设备相当于是区块链网络的中心节点，而第一电子设备和第三电子设备则相当于区块链网络的普通节点。
其中，照片信息可以以记录的形式添加到共享相簿中，例如第二照片信息对应第一记录包括第一标识、所述第二照片的哈希值和所述第二照片的内容数据；第三照片信息对应的第二记录包括第二标识、第二照片的哈希值和第三照片的内容数据，以及第一标识。也就是说第二记录是与第一记录相关联的。结合本申请实施例提供的区块链技术举例来说，第一记录相当于图4b中子区块11，第二记录相当于图4b中的子区块12。
在本申请一种可能的实施例中，当第一电子设备与第二电子设备未发起同步时，第一电子设备检测到用户的第四操作；响应于第四操作，第一电子设备将第一共享相簿中的第三照片信息删除。当第一电子设备与第二电子设备发起同步时，第一电子设备向第二电子设备发送删除第三照片信息的第四请求消息；第一电子设备接收第二电子设备发送的删除成功第三照片信息的第四请求响应消息。
结合上述场景图13来说，电子设备2在没有与电子设备1建立网络连接时，电子设备2删除了图13b中的图片802。当电子设备2与电子设备1建立网络连接时，电子设备2向电子设备1发送删除该图片802的请求消息，电子设备1将“家庭照片”中的照片802删除成功后，向电子设备2返回删除成功的响应消息，这样“家庭照片”这一空间中的照片802就被删除了。
本申请其他一些实施例提供了另一种照片共享方法，如图22所示，该方法包括：2201、第二电子设备建立与第一电子设备的网络连接。例如，第一电子设备和第二电子设备可以 基于wifi热点、wifi直连、蓝牙、zigbee或NFC等通信网络近距离连接。2202、第二电子设备接收第一电子设备发送的添加第一照片信息的第一请求消息。2203、响应于该第一请求消息，第二电子设备向第一电子设备发送拒绝添加第一照片信息的第一请求响应消息。
结合上述场景图11和图12来说，第一电子设备相当于图中的电子设备2，第二电子设备相当于图中的电子设备1。另外，第一照片信息可以直接指第一照片，也可以指与第一照片对应的索引信息，例如链接信息或与第一照片的缩略图等。结合图12来说，第一照片信息相当于图12中的第三照片。因第二电子设备的上述执行步骤与第一电子设备相对应，所以具体内容可以参见上文介绍，本实施例中不再重复赘述。
