在相关技术中，可以通过设置密码对文件进行加密，但这种加密方式将文件中的可公开的内容也一并进行了加密，且加密方式单一，每次查看加密文件中的可公开的内容时，都需要重新输入一次密码，使得用户查看加密文件的效率不高。
本申请实施例提供一种数据加密方法、装置、设备以及可读存储介质，可以丰富对数据的加密方式，且可以提高数据查看效率。图1是本申请实施例提供的一种本申请实施例提供的数据加密方法所适用的网络架构图。如图1所示，该网络架构可以包括业务服务器2000和用户终端集群，所述用户终端集群可以包括多个用户终端，如图1所示，具体可以包括用户终端100a、用户终端100b、用户终端100c、…、用户终端100n。
如图1所示，用户终端100a、用户终端100b、用户终端100c、…、用户终端100n可以分别与所述业务服务器2000进行网络连接，以便于每个用户终端可以通过该网络连接与业务服务器2000进行数据交互。
如图1所示，该用户终端集群中的每个用户终端均可以集成安装有目标应用，当该目标应用运行于各用户终端中时，可以分别与上述图1所示的业务服务器2000之间进行数据交互。其中，该目标应用可以包括具有显示文字、图像、音频以及视频等数据信息功能的应用。
本申请实施例可以在图1所示的多个用户终端中选择一个用户终端作为目标用户终端，该目标用户终端可以包括：智能手机、平板电脑、桌上型电脑等携带显示和播放数据信息功能的智能终端。例如，本申请实施例可以将图1所示的用户终端100a作为该目标用户终端，该目标用户终端中可以集成有上述目标应用，此时，该目标用户终端可以通过该目标应用对应的业务数据平台与业务服务器2000之间实现数据交互。
