Description

一种无线展示方法及用户终端 技术领域
本发明涉及互联网技术领域，尤其涉及一种无线展示方法及用户终端。
背景技术
随着智能终端(如智能手机、PAD等)的发展，越来越多的智能终端拥有WFD(Wi-Fi Display，无线视频展示)功能，WFD功能又称为无线展示功能。无线展示功能是一种通过无线WiFi将智能终端展示的内容发送给展示设备，通过展示设备来展示智能终端展示的内容的功能。
在现有技术中，展示设备在展示智能终端的内容时，会将智能终端的整个屏幕内容都展示出来。例如，在展示设备展示智能终端的内容的过程中，若智能终端接收到来电，则来电号码将在展示设备中展示出来；或在展示设备展示智能终端的内容的过程中，若智能终端将收到的短信在状态栏上滚动显示，将导致用户的隐私信息暴露在公众场合。因此，在现有技术中，展示设备在展示智能终端的内容的过程中，容易造成用户隐私的泄露。
发明内容

检测模块，用于在所述安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧；
发送模块，用于当所述检测模块检测所述待发送信息帧为所述隐私信息帧时，按照预设的隐私信息帧发送规则向所述展示设备发送不包括所述隐私信息的信息帧。
在本发明实施例中，用户终端启动安全展示模式之后，将在安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧；当待发送信息帧为隐私信息帧时，按照预设的隐私信息帧发送规则向展示设备发送不包括隐私信息的信息帧。可见，通过实施本发明实施例，当待发送信息帧为隐私信息帧时，用户终端将发送不包括隐私信息的信息帧至展示设备进行无线展示，从而在进行无线展示的过程中，提高了隐私信息的安全性。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳 动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种无线展示方法及用户终端，能够在展示设备展示用户终端的内容的过程中，提高用户隐私的安全性。以下分别进行详细说明。
请参见图1，图1为本发明实施例公开的一种无线展示方法的流程示意图。如图1所示，该无线展示方法可以包括以下步骤。
S101、启动安全展示模式。
本发明实施例中，由用户终端启动安全展示模式。其中，该用户终端可包括但不限于智能手机、掌上电脑、笔记本电脑和台式电脑等用户终端。该用户终端的操作系统可包括但不限于Android操作系统、IOS操作系统、Symbian(塞班)操作系统、Black Berry(黑莓)操作系统、Windows Phone8操作系统等等，本发明实施例不做限定。
本发明实施例中，安全展示模式为用户终端的用于进行无线展示的模式。用户终端可拥有一个用于进行无线展示的模式，或用户终端可拥有多个用于进行无线展示的模式，本发明实施例不做限定。当用户终端拥有一个用于进行无线展示的模式时，该用于进行无线展示的模式为安全展示模式。
S102、在所述安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧。
本发明实施例中，用户终端在进行无线展示时，是将一帧一帧的图像发送至展示设备进行展示。本发明实施例中的待发送信息帧为即将发送至展示设备进行展示的包括用户终端屏幕内容的一图像帧。其中，该展示设备可包括但不限于投影仪、电视机、台式电脑、笔记本电脑、掌上电脑和智能手机等等，本发明实施例不做限定。
本发明实施例中，用户终端在启动安全展示模式之后，将在安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧。当用户终端检测待发送信息帧为包括隐私信息的隐私信息帧时，执行步骤S103；当用户终端检测待发送信息帧不为包括隐私信息的隐私信息帧时，用户终端将待发送信息帧发送至展示设备进行展示。
作为一种可选的实施方式，用户终端在安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧的具体实施方式可以为：
11)用户终端在安全展示模式下，检测隐私应用是否输出隐私信息；
12)当检测到所述隐私应用输出隐私信息时，用户终端检测待发送至展示设备进行无线展示的待发送信息帧中是否包含所述隐私应用输出的隐私信息；
13)当所述待发送信息帧中包含所述隐私应用输出的隐私信息时，用户终端确定所述待发送信息帧为隐私信息帧。
在该实施方式中，可选的，用户可在用户终端预先设置隐私应用，例如用户可将短信应用、及时通信应用或锁屏应用等设置为隐私应用。在该实施方式中，隐私应用的所有输出信息为隐私信息。当用户终端识别待发送至展示设备进行无线展示的待发送信息帧中包含隐私应用输出的隐私信息时，用户终端确定待发送信息帧为隐私信息帧，则执行步骤S103。当用户终端识别待发送至展示设备进行无线展示的待发送信息帧中不包含隐私应用输出的隐私信息时，用户终端将待发送信息帧发送至展示设备进行展示。
S103、按照预设的隐私信息帧发送规则向所述展示设备发送不包括所述隐私信息的信息帧。
本发明实施例中，当用户终端检测待发送信息帧为包括隐私信息的隐私信息帧时，用户终端将去除隐私信息帧，并向展示设备发送不包括隐私信息的信息帧。
作为一种可选的实施方式，用户终端按照预设的隐私信息帧发送规则向展示设备发送不包括隐私信息的信息帧的具体实施方式为：
用户终端将所述隐私信息帧去除，并将不包括所述隐私信息的预设信息帧发送至所述展示设备。
在该实施方式中，用户终端预先设置有预设信息帧，该预设信息帧为不包括隐私信息的图片帧。该预设信息帧可以由用户进行设置。若待发送信息帧为隐私信息帧，则用户终端将隐私信息帧去除，并将预设信息帧作为待发送信息帧发送至展示设备，以使展示设备对预设信息帧进行展示。通过向展示设备发送不包括隐私信息的预设信息帧，使展示设备展示预设信息帧，可提示用户隐私应用存在输出信息，以使用户能够及时处理隐私应用的输出信息，增加了用户体验。
可选的，用户终端可预先设置多个预设信息帧，不同的隐私信息可对应不同的预设信息帧。例如，可预先设置短信内容隐私信息对应预设信息帧1，设置 及时通信应用隐私信息对应预设信息帧2；当隐私信息帧包括的隐私信息为短信内容时，可将预设信息帧1作为待发送信息帧发送至展示设备进行展示；同理当隐私信息帧包括的隐私信息为及时通信应用的输出内容时，可将预设信息帧2作为待发送信息帧发送至展示设备进行展示。其中，预设信息帧1可包括用于提示存在未读短信内容的提示内容，预设信息帧2可包括用于提示存在未读及时通信应用信息的提示内容。通过这种方式，不仅提高了隐私信息的安全性，而且可精确地提示用户当前输出隐私信息的是什么隐私应用，可使用户及时处理隐私信息，提高了用户体验。
作为一种可选的实施方式，用户终端按照预设的隐私信息帧发送规则向展示设备发送不包括隐私信息的信息帧的具体实施方式为：
21)用户终端将所述隐私信息帧去除，并将已发送至所述展示设备的信息帧中发送时间与当前时间最接近的信息帧作为目标信息帧；
22)用户终端发送所述目标信息帧至所述展示设备。
该实施方式的具体实现请参见图2所描述的实施例。
在图1所描述的方法中，用户终端启动安全展示模式之后，将在安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧；当待发送信息帧为隐私信息帧时，按照预设的隐私信息帧发送规则向展示设备发送不包括隐私信息的信息帧。可见，通过实施本发明实施例，当待发送信息帧为隐私信息帧时，用户终端将发送不包括隐私信息的信息帧至展示设备进行无线展示，从而在进行无线展示的过程中，提高了隐私信息的安全性。
请参见图2，图2为本发明实施例公开的另一种无线展示方法的流程示意图。如图2所示，该无线展示方法可以包括以下步骤。
S201、用户终端启动安全展示模式。
S202、用户终端在所述安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧。
本发明实施例中，当用户终端检测待发送信息帧为包括隐私信息的隐私信息帧时，执行步骤S203；当用户终端检测待发送信息帧不为包括隐私信息的隐私信息帧时，用户终端将待发送信息帧发送至展示设备进行展示。
S203、用户终端将所述隐私信息帧去除，并将已发送至所述展示设备的信息帧中发送时间与当前时间最接近的信息帧作为目标信息帧。
本发明实施例中，当用户终端判断待发送信息帧为隐私信息帧时，用户终端将隐私信息帧去除，并将已发送至所述展示设备的信息帧中发送时间与当前时间最接近的信息帧作为目标信息帧。
举例来说，若用户终端依次向展示设备发送了信息帧1、信息帧2，若当前获取的待发送至展示设备的待发送信息帧为隐私信息帧，则用户终端将已发送至展示设备的信息帧2作为目标信息帧。
S204、用户终端发送所述目标信息帧至所述展示设备。
本发明实施例中，用户终端获取目标信息帧之后，发送目标信息帧至展示设备，以使展示设备对目标信息帧进行展示。
本发明实施例中，当待发送信息帧为隐私信息帧时，通过将隐私信息帧去除，并向展示设备发送不包括隐私信息的目标信息帧，可提高隐私信息的安全性。
S205、用户终端终止隐私应用对隐私信息的输出。
本发明实施例中，用户终端向展示设备发送目标信息帧之后，用户终端将终止隐私应用对隐私信息进行输出。例如，当隐私应用为通信应用时，若待发送信息帧中包括通信应用输出的来电号码，则用户终端向展示设备发送目标信息帧之后，用户终端将挂断来电，以终止通信应用对隐私信息的输出。
本发明实施例中，当用户在重要会议使用无线展示功能时，若突然用户终端接收到来电或短信等，将严重影响会议和用户。因此，通过在向展示设备发送目标信息帧之后，终止隐私应用对隐私信息的输出，可使用户不被来电或短信的打扰，继续对会议内容进行无线展示，提高了用户体验。且对于观看展示设备展示的内容的用户来说，由于观看的用户不会从展示设备展示的内容中看见来电信息或短信息，因此观看的用户不会被来电或短信所干扰，且用户看到的展示设备展示的会议内容是连贯的，提高了用户体验。
请参见图3，图3为本发明实施例公开的另一种无线展示方法的流程示意图。如图3所示，该无线展示方法可以包括以下步骤。
S301、用户终端向展示设备发送连接请求。
本发明实施例中，可选的，用户终端可通过无线WIFI向展示设备发送连接请求。
本发明实施例中，可选的，用户终端向展示设备发送的连接请求可以携带用户终端的唯一标识信息。
在该实施方式中，展示设备可以预先设置终端标识信息库，该终端标识信息库包括允许与该展示设备建立连接的用户终端的唯一标识信息。在展示设备接收到用户终端发送的携带有用户终端的唯一标识信息的连接请求之后，展示设备可以在预先设置的终端标识信息库中查找是否存在该用户终端的唯一标识信息，若存在，则展示设备向用户终端发送针对该连接请求的允许响应；若不存在，则展示设备不向用户终端发送针对该连接请求的允许响应。通过这种方式可以避免其他非法用户终端与展示设备建立连接，对展示设备进行非法控制。
S302、用户终端接收所述展示设备响应所述连接请求发送的允许响应，并根据所述允许响应建立与所述展示设备的连接。
本发明实施例中，用户终端接收展示设备响应该连接请求发送的允许响应之后，将根据该允许响应建立与展示设备的连接。
S303、用户终端接收用户输入的展示模式选择指令。
本发明实施例中，用户终端有多种无线展示模式，可包括但不限于非安全展示模式、标准展示模式和安全展示模式等。
其中，在非安全展示模式下，若待发送信息帧为隐私信息帧，则直接发送待发送信息帧到展示设备进行展示。非安全展示模式适用于只有用户一个人的环境下。
其中，在标准展示模式下，若待发送信息帧为隐私信息帧，则用户终端发送第一帧隐私信息帧至展示设备进行展示，至到隐私应用将隐私信息输出完毕。例如，若需依次发送信息帧L1、L2和L3至展示设备，若信息帧L1、L2和L3为隐私信息帧，则用户终端在发送信息帧L2时，将信息帧L1取代信息帧L2发送至展示设备，用户终端在发送信息帧L3时，将信息帧L1取代信息帧L3发送至展示设备(即用户终端在发送信息帧L1、L2和L3时，将重复发送三次信息帧L1至展示设备)。
标准展示模式可适用于用户与较为亲密或信赖的友人在一起的环境下，在标准展示模式下，展示设备将只展示第一帧隐私信息帧，不会展示所有的隐私 信息帧，因此，也提高了用户隐私信息的安全性，且展示第一帧隐私信息帧也可提示用户当前有隐私信息输出，以使用户能够及时对隐私信息进行处理。
在本发明实施例中，终端拥有多种无线展示模式，用户可根据当前所处环境和需求来灵活地选择展示模式，提高了用户体验。
S304、用户终端响应所述展示模式选择指令，启动所述展示模式选择指令选择的安全展示模式。
S305、用户终端在所述安全展示模式下，检测待发送至展示设备进行无线展示的待发送信息帧是否为包括隐私信息的隐私信息帧。
本发明实施例中，当用户终端检测待发送信息帧为包括隐私信息的隐私信息帧时，执行步骤S306；当用户终端检测待发送信息帧不为包括隐私信息的隐私信息帧时，用户终端将待发送信息帧发送至展示设备进行展示。
S306、用户终端按照预设的隐私信息帧发送规则向所述展示设备发送不包括所述隐私信息的信息帧。
可见，通过实施图3所描述的实施例，用户可根据当前所处环境和需求来灵活地选择展示模式，提高了用户体验，且当用户选择安全展示模式时，在展示设备进行展示的过程中，能够提高用户隐私的安全性。
请参阅图4，图4是本发明实施例公开的一种用户终端的结构示意图。其中，图4所示的用户终端可以包括启动模块401、检测模块402和发送模块403。其中：

本发明实施例中，当检测模块402检测待发送信息帧为包括隐私信息的隐私信息帧时，触发发送模块403将去除隐私信息帧，并向展示设备发送不包括隐私信息的信息帧。
作为一种可选的实施方式，发送模块403具体用于：
将所述隐私信息帧去除，并将不包括所述隐私信息的预设信息帧发送至所述展示设备。
在该实施方式中，用户终端预先设置有预设信息帧，该预设信息帧为不包括隐私信息的图片帧。该预设信息帧可以由用户进行设置。若待发送信息帧为隐私信息帧，则发送模块403将隐私信息帧去除，并将预设信息帧作为待发送信息帧发送至展示设备，以使展示设备对预设信息帧进行展示。通过向展示设备发送不包括隐私信息的预设信息帧，使展示设备展示预设信息帧，可提示用户隐私应用存在输出信息，以使用户能够及时处理隐私应用的输出信息，增加 了用户体验。
可选的，用户终端可预先设置多个预设信息帧，不同的隐私信息可对应不同的预设信息帧。例如，可预先设置短信内容隐私信息对应预设信息帧1，设置及时通信应用隐私信息对应预设信息帧2；当隐私信息帧包括的隐私信息为短信内容时，可将预设信息帧1作为待发送信息帧发送至展示设备进行展示；同理当隐私信息帧包括的隐私信息为及时通信应用的输出内容时，可将预设信息帧2作为待发送信息帧发送至展示设备进行展示。其中，预设信息帧1可包括用于提示存在未读短信内容的提示内容，预设信息帧2可包括用于提示存在未读及时通信应用信息的提示内容。通过这种方式，不仅提高了隐私信息的安全性，而且可精确地提示用户当前输出隐私信息的是什么隐私应用，可使用户及时处理隐私信息，提高了用户体验。
作为一种可选的实施方式，发送模块403具体用于：
将所述隐私信息帧去除，并将已发送至所述展示设备的信息帧中发送时间与当前时间最接近的信息帧作为目标信息帧；

本发明实施例中，当检测模块判断待发送信息帧为隐私信息帧时，发送模块403将隐私信息帧去除，并将已发送至所述展示设备的信息帧中发送时间与当前时间最接近的信息帧作为目标信息帧。
举例来说，若用户终端依次向展示设备发送了信息帧1、信息帧2，若当前获取的待发送至展示设备的待发送信息帧为隐私信息帧，则发送模块403将已 发送至展示设备的信息帧中发送时间与当前时间最接近的信息帧作为目标信息帧(即将信息帧2作为目标信息帧)。

终止模块404，用于在所述发送模块403发送所述目标信息帧至所述展示设备之后，终止隐私应用对隐私信息的输出。
本发明实施例中，例如，当隐私应用为通信应用时，若待发送信息帧中包括通信应用输出的来电号码，则发送模块403向展示设备发送目标信息帧之后，终止模块404将挂断来电，以终止通信应用对隐私信息的输出。
本发明实施例中，当用户在重要会议使用无线展示功能时，若突然用户终端接收到来电或短信等，将严重影响会议和用户。因此，通过在向展示设备发送目标信息帧之后，终止隐私应用对隐私信息的输出，可使用户不被来电或短信的打扰，继续对会议内容进行无线展示，提高了用户体验。且对于观看展示设备展示的内容的用户来说，由于观看的用户不会从展示设备展示的内容中看见来电信息或短信息，因此观看的用户不会被来电或短信所干扰，且用户看到的展示设备展示的会议内容是连贯的，提高了用户体验。

其中，在非安全展示模式下，若待发送信息帧为隐私信息帧，则直接发送待发送信息帧到展示设备进行展示。非安全展示模式适用于只有用户一个人的环境下。
其中，在标准展示模式下，若待发送信息帧为隐私信息帧，则用户终端发送第一帧隐私信息帧至展示设备进行展示，至到隐私应用将隐私信息输出完毕。例如，若需依次发送信息帧L1、L2和L3至展示设备，若信息帧L1、L2和L3为隐私信息帧，则用户终端在发送信息帧L2时，将信息帧L1取代信息帧L2发送至展示设备，用户终端在发送信息帧L3时，将信息帧L1取代信息帧L3发送至展示设备(即用户终端在发送信息帧L1、L2和L3时，将重复发送三次信息帧L1至展示设备)。
标准展示模式可适用于用户与较为亲密或信赖的友人在一起的环境下，在标准展示模式下，展示设备将只展示第一帧隐私信息帧，不会展示所有的隐私信息帧，因此，也提高了用户隐私信息的安全性，且展示第一帧隐私信息帧也可提示用户当前有隐私信息输出，以使用户能够及时对隐私信息进行处理。
