Description

数据分享方法、终端及*** 技术领域
本公开涉及通信技术，尤其涉及一种数据分享方法、终端及***。
背景技术
在当今快节奏的工作与生活中，智能终端如手机对于人们而言已经成为一种必不可少的通信工具。此外，数据传播或分享的渠道也异常丰富，不仅有正式的各种书信，也有腾讯QQ、微信等即时通讯(Instant Messenger，IM)工具和社交平台，以及各种工具软件比如文件传输协议(File Transfer Protocol，FTP)、迅雷等。每种数据传播的渠道具有各自的优势，能够在各种场景下提供给用户多种选择。
现有数据传播的渠道有时也无法覆盖很多场景，存在一些不足之处：一方面，手机所处的位置没有网络信号、或者手机所处的位置网络信号质量较差、或者手机欠费时，无法快速将数据比如短消息迅速传播出去；当用户处在紧急情况下而不方便拨打电话、发送短信以及使用及时聊天工具时，无法快速发出求救消息；以及手机所处的位置有网络信号，但是数据所包含的内容较大，需要耗费大量移动数据流量进行数据传播；另一方面，无法将分享的数据限定在某个大区域、或某个群组、或某个时间段内传播，并快速实现预期效果，例如，在商场寻找走失儿童时，无法使求助信息限定处在商场内部的手机中第一时间进行流转；需要分享的数据无法通过一个接收方传播给另一个接收方，以迅速传播到位；以及无法实现通过第三方将分享的数据传播给接收方。

具体实施方式
图1为根据本公开实施例的数据分享方法的流程示意图。
如图1所示，根据本实施例的数据分享方法包括步骤101至步骤104。
在步骤101，第一终端获取待分享数据的分享模式。
第一终端可以接收设置指令，并根据设置指令生成待分享数据的分享模式，即，获取待分享数据的分享模式。
设置指令可以是用户通过在第一终端的屏幕上或安装的数据分享应用的界面上执行触摸、输入等操作进行设置而生成的，也可以是第三方终端设备根据数据分享要求所生成，并通过与第三方终端设备相连的第一终端的外部接口(比如通用串行总线接口)向第一终端发送的。待分享数据可以是第一终端中已存储的数据(比如已存储的图片、日志等)，也可以是第一终端当前实时获取的数据(比如第一终端当前拍摄的照片、编辑的文本文件和短信消息等)。若设置指令是 由第三方终端设备发送给第一终端的，则待分享数据还可以包含于设置指令中。此外，设置指令还可包含指定待分享的数据的指令，第一终端可根据设置指令来指定待分享数据。待分享数据也可以是第一终端在接收到设置指令之前，第一终端的用户已确定的待分享的数据。
设置指令可以包含对于待分享数据的分享方法，第一终端根据设置指令可将分享方法作为对于待分享数据的分享模式。分享模式可以至少包括传播方式。此外，分享模式还可包括接收终端标识列表和传播区域中的至少之一。
传播方式用于限定允许待分享数据以何种方式进行传播，并且可包括第一传播模式、第二传播模式等。
第一传播模式也可称为借力传播模式，即，当两个人之间相隔较远而无法相互直接传播待分享数据时，可以通过处于行走状态的中间者进行间接传播。在第一传播模式下，先由发送方将待分享数据分享给一个或一个以上中间者，再通过一个或一个以上中间者将待分享数据分享给目的接收方，以快速完成待分享数据的分享。简而言之，第一传播模式为发送终端将待分享数据经由第三方终端分享给接收终端。在第一传播模式中，会在数据分享过程中对待分享数据进行加密，以使中间者在传播数据的过程中无法直接查看待分享数据。
第二传播模式也可称为多点续传模式，即，在最开始分享待分享数据的数据源只有一个，经过一次数据传播后，可分享待分享数据的数据源就变成了两个。以此方式，可分享待分享数据的数据源可以呈指数级增长，以实现快速分享待分享数据。简而言之，第二传播模式为接收终端接收到待分享数据后继续向其他接收终端发送待分享数据。
接收终端标识列表为可接收待分享数据、且可直接查看待分享数据的所有终端的标识所组成的列表。接收终端标识列表可包含一个或一个以上终端的标识。终端的标识可以是终端的国际移动用户识别码(IMSI)、终端的国际移动设备身份码(IMEI)、终端的用户的手机号码，也可以是预先为终端设置的编号等。在实际应用中，可预先将多个终端的标识作为一个群组列表存入第一终端的数据库中。
传播区域用于限定待分享数据能够进行分享的某一个或多个设定的区域范围，比如，允许在某一个小区附近100米范围内分享数据。
在步骤102，第一终端创建以自身为无线接入点的第一无线局域网。
第一无线局域网可以是基于近场通信(Near Field Communication，NFC)或蓝牙等技术创建的。第一终端在创建以第一终端为无线接入点的第一无线局域网时，可以生成无线接入点的接入密码和无线接入点的名称，也可以不生成无线接入点的接入密码而仅生成无线接入点的名称。无线接入点的名称用于区分不同的无线接入点，并且可以根据第一终端的型号、性能等参数生成。无线接入点的接入密码用于验证是否允许除第一终端以外的终端接入该无线接入点，并且只有在接入密码正确的情况下，才允许接入。无线接入点的接入密码可以是随机产生的一位或一位以上的随机数，也可以是预先设置的一个数字组合。当第一终端确定有数据需要进行分享时，作为发送方创建第一无线局域网，然后可周期性的再次创建和关闭以第一终端为无线接入点的第一无线局域网，以节省第一终端的电源、内存等资源的消耗。此外，当第一终端多次创建以自身为无线接入点的第一无线局域网时，每次生成的无线接入点的接入密码可相同。
在步骤103，第一终端接收第二终端发送的第一连接请求。
当第一终端创建了第一无线局域网后，第二终端搜索由第一终端创建的以第一终端为无线接入点的第一无线局域网，并向搜索到的第一终端发送第一连接请求，以请求连接第一无线局域网。第一终端可以接收第二终端发送的第一连接请求。
第一终端也可以接收一个以上第二终端向第一终端发送的第一连接请求，也就是说第一终端可以同时或在一定时间段内接收由多个第二终端发送的第一连接请求。第一连接请求中可包含无线接入点的名称和/或无线接入点的接入密码和/或第二终端的标识。连接请求可以是传输控制协议(Transmission Control Protocol，TCP)连接请求。
在步骤104，第一终端基于第一连接请求和/或分享模式确定允 许第二终端接收待分享数据时，第一终端与第二终端建立数据通信连接，并将待分享数据和分享模式向第二终端发送。
第一终端基于第一连接请求和/或分享模式确定是否允许第二终端接收待分享数据至少可包括以下四种情形：
情形一、第一终端基于第一连接请求和分享模式确定是否允许第二终端接收待分享数据，即，第一终端确定分享模式包括第二传播模式和接收终端标识列表，并且第一连接请求包括第二终端的标识且第二终端的标识包括在接收终端标识列表时，可以允许第二终端接收待分享数据；
情形二、第一终端基于分享模式确定是否允许第二终端接收待分享数据，即，第一终端确定分享模式包括第二传播模式时，可以允许第二终端接收待分享数据；
情形三、第一终端基于分享模式确定是否允许第二终端接收待分享数据，即，第一终端确定分享模式包括接收终端标识列表和/或第一传播模式时，可以允许第二终端接收待分享数据；
情形四、第一终端基于第一连接请求确定是否允许第二终端接收待分享数据，即，当第一连接请求包括无线接入点的名称和无线接入点的接入密码，并且第一终端对第一连接请求中的无线接入点的接入密码的验证通过时，可以允许第二终端接收待分享数据。
对于情形一，由于第二终端的标识属于接收终端标识列表，表明第二终端是待分享数据的接收方，因此，第一终端可将待分享数据分享给第二终端。当第二终端接收到第一终端发送的待分享数据和待分享数据的分享模式后，若接收终端标识列表中还包含除第二终端的标识以外的终端标识，则第二终端可创建以自身为无线接入点的第二无线局域网，以继续分享待分享数据。
对于情形二，此时分享模式未限定待分享数据的接收方，即，除第一终端以外的终端都有可能获取到待分享数据，并且适用于在一定范围或区域内传播数据，例如，当需要对某一商场内的所有人员发布紧急通知时，采用不限定紧急通知的接收方的分享模式，从而能够实现快速在商场内传播该紧急通知。
对于情形三，此时第二终端的标识可属于接收终端标识列表，也可不属于接收终端标识列表。当第二终端的标识属于接收终端标识列表时，表明第二终端是待分享数据的目的接收方，当第二终端的标识不属于接收终端标识列表时，表明第二终端是中间者，而不是待分享数据的目的接收方，则第二终端需要继续分享待分享数据，以使待分享数据的目的接收方能够尽快获取到。
对于情形四，当第一终端对第一连接请求中的无线接入点的接入密码的验证通过时，表明第二终端是待分享数据的目的接收方，因为在无线接入点的接入密码只有第一终端的用户知悉的情况下，第二终端的用户只有在被第一终端的用户告知的情况下才能知道无线接入点的接入密码，说明第一终端的用户愿意将待分享数据分享给第二终端的用户，即，第一终端可将待分享数据分享给第二终端。
综上，当分享模式为第一传播模式时，第一终端基于分享模式确定允许第二终端接收待分享数据的步骤包括：允许第二终端经由至少一个第三终端接收待分享数据，第三终端连接于第一终端和第二终端之间；当分享模式为第二传播模式时，第一终端基于分享模式确定允许第二终端接收待分享数据的步骤包括：允许第二终端接收第一终端发送的待分享数据，并在第一终端向另一第二终端发送待分享数据时，由各第二终端将接收到的待分享数据发送给至少一个第三终端。
第一终端、第二终端、第三终端在这里只是为了区分不同的终端，以便更清楚的说明技术方案。在实际应用中，第一终端既可以做发送终端，也可以做接收终端，还可以做中转终端。
对于上述情形一、情形二和情形三而言，第一终端创建的第一无线局域网没有设置接入密码而仅设置有名称。此时，第二终端根据发送给第一终端的第一连接请求可连接第一无线局域网，随后第一终端与第二终端建立数据通信连接，以使第一终端与第二终端之间能够进行数据传输。数据通信连接可以是TCP连接、Socket连接等。另一方面，对于上述情形一、情形二和情形三而言，如果第一终端创建的第一无线局域网设置有无线接入点的接入密码和无线接入点的名称，则在满足上述情形一、或情形二、或情形三的情况下，第一终端 还需要对第一连接请求中的无线接入点的接入密码进行验证，并且在验证通过后，才能确定允许第二终端接收待分享数据。
综上所述，根据本公开实施例的数据分享方法能够在第一终端与第二终端之间分享数据时不需要耗费双方任何终端的移动数据流量，从而实现在没有网络信号覆盖或网络信号质量较差时，第一终端与第二终端之间仍可进行数据分享。
根据本公开实施例，在上述步骤104之后，该方法还可包括：第一终端搜索由第四终端创建的以第四终端为无线接入点的第二无线局域网，以获取第四终端分享的目标数据。
由于第一终端也可能需要接收其它终端所分享的数据，因此在第一终端作为发送终端创建以自身为无线接入点的第一无线局域网的一段时间(比如10分钟)之后，第一终端可以作为接收终端自动搜索由其它终端(比如第四终端)创建的无线局域网以获取其它终端分享的目标数据。如果第一终端作为发送方在一定时间(比如20分钟)内没有接收到连接请求(即没有发现接收终端)，或者第一终端作为接收终端在一定时间(比如15分钟)内没有搜索到无线局域网(即没有发现发送终端)，则可暂时保持静默，以关闭WiFi或蓝牙等开关，并在一段时间后再次创建无线局域网或搜索无线局域网，从而节约电源消耗。
上述第四终端实际上也可以是前述实施例中的第二终端、第三终端中的任何一个。此外，可以预设算法控制第一终端在发送方与接收方之间的切换。当第一终端获取到待分享数据或确定需要进行数据分享时，根据预设算法可自动将第一终端切换为发送方，即，使第一终端创建第一无线局域网；当第一终端分享完待分享数据或者无数据分享时，根据预设算法可自动将第一终端切换为接收方，即，使第一终端搜索可接入的无线局域网，以获取目标数据。
根据本公开实施例，在上述步骤102之前，该方法还可包括：第一终端获取自身当前所处位置，并且确定自身当前所处位置属于预先设置的传播区域时，允许创建以自身为无线接入点的第一无线局域网。
当第一终端确定有数据需要进行分享时，第一终端获取自身当前所处位置，并判断自身当前所处位置是否属于预先设置的传播区域。若确定自身当前所处位置属于传播区域，则允许第一终端创建以自身为无线接入点的第一无线局域网；若确定自身当前所处位置不属于传播区域，则不允许第一终端创建以自身为无线接入点的第一无线局域网。
传播区域也可包含于分享模式中。由于第一终端创建的以自身为无线接入点的第一无线局域网的通信距离是有限的，因此通过限定传播区域，在确定自身当前所处位置属于传播区域时，才允许第一终端创建以自身为无线接入点的第一无线局域网，可以更好地节省资源并加快数据分享效率。
述分享模式还可以包括销毁条件，以使第二终端在确定满足销毁条件时销毁待分享数据。
销毁条件可以包括销毁时间、销毁方式等内容。销毁时间可以是一个具体的时间点(比如十点二十分)，也可以是一个时间段(比如三十分钟)。例如，当销毁时间为一个小时时，若第二终端接收到待分享数据达到了一个小时，则使第二终端销毁接收到的待分享数据。
为了保证待分享数据的安全性和私密性以及减少终端中内存的消耗，通过在分享策略中设置销毁条件，使接收到待分享数据的第二终端在确定达到销毁条件时，自动销毁接收到待分享数据。
根据本公开实施例，该方法还包括：第一终端向第二终端发送加密指令，以使第二终端根据加密指令对待分享数据进行加密。
当分享模式包括接收终端标识列表和第一传播模式，且第一终端确定第二终端的标识不属于接收终端标识列表时，第一终端向第二终端发送加密指令，以使第二终端根据加密指令对待分享数据进行加密。
加密指令可以包含第一终端的标识、加密方法等内容。当分享模式包括接收终端标识列表和第一传播模式，且第一终端确定第二终端的标识不属于接收终端标识列表时，可知第二终端是中间者而不是待分享数据的目的接收方。因此，第一终端向第二终端发送加密指令， 以使第二终端根据加密指令对待分享数据进行加密，使第二终端无法直接查看待分享数据，从而保证待分享数据的安全性和私密性。
图2为根据本公开实施例的第一终端的结构示意图。
如图2所示，根据本公开实施例的第一终端1包括第一接收单元10、第一创建单元11、第二接收单元12、第一处理单元13和第一发送单元14。
第一接收单元10设置为获取待分享数据的分享模式。第一创建单元11设置为创建以第一终端为无线接入点的第一无线局域网。第二接收单元12设置为接收第二终端发送的第一连接请求。第一处理单元13设置为基于第一连接请求和/或分享模式确定允许第二终端接收待分享数据时，与第二终端建立数据通信连接。第一发送单元14设置为将待分享数据和分享模式向第二终端发送。
第一接收单元10获取待分享数据的分享模式的方式、第一创建单元11创建以第一终端为无线接入点的第一无线局域网的方式、第二接收单元12接收第二终端发送的第一连接请求的方式、第一处理单元确定允许第二终端接收待分享数据的方式和与第二终端建立数据连接的方式、以及第一发送单元14将待分享数据和分享模式向第二终端发送的方式，分别与上述参考图1描述的步骤101、步骤102、步骤103和步骤104实质上相同，这里不作赘述。
根据本公开实施例，第一终端1还可包括第一搜索单元15，其设置为搜索由第四终端创建的以第四终端为无线接入点的第二无线局域网，以获取第四终端分享的目标数据。
关于第一搜索单元15的描述可以参考上述实施例中在步骤104之后执行的搜索第二无线局域网的步骤，这里不作赘述。
根据本公开实施例，第一终端1还可包括位置获取单元16，其设置为获取第一终端当前所处位置。
关于位置获取单元16的描述可以参考上述实施例中在步骤102之前执行的获取自身当前所处位置的步骤，这里不作赘述。
此外，根据本实施例的第一终端可以向第二终端发送包括销毁条件的分享模式，并且还可以向第二终端发送加密指令。关于销毁条 件和加密指令的描述可以参考上述实施例中的相关描述，这里不作赘述。
图3为根据本公开实施例的数据分享方法的流程示意图。
如图3所示，根据本实施例的数据分享方法包括步骤201至步骤204。
在步骤201，第二终端搜索由第一终端创建的以第一终端为无线接入点的第一无线局域网。
当需要进行数据分享时，第二终端开启无线接入点搜索功能，搜索由第一终端创建的以第一终端为无线接入点的第一无线局域网。第二终端开启无线接入点搜索功能可以是第二终端开启WiFi。
在步骤202，第二终端向搜索到的第一终端发送第一连接请求。
当在步骤201中第二终端搜索到由第一终端创建的以第一终端为无线接入点的第一无线局域网后，第二终端向搜索到的第一终端发送第一连接请求，以请求连接第一无线局域网。
第一连接请求中可包含无线接入点的名称和/或无线接入点的接入密码和/或第二终端的标识。第一连接请求中的无线接入点的接入密码可由第二终端的用户进行设置。
在步骤203，在第一终端确定允许第二终端接收待分享数据时，第二终端与第一终端建立数据通信连接。
在第一终端基于第一连接请求和/或待分享数据的分享模式确定允许第二终端接收待分享数据时，第二终端与第一终端建立数据通信连接。
待分享数据的分享模式可由第一终端根据接收到的设置指令进行设置。数据通信连接可以是TCP连接、Socket连接等。分享策略至少包括传播方式，还可包括接收终端标识列表和传播区域中的至少之一。
关于传播方式和接收终端标识列表的描述可以参考上述结合图1描述的实施例，这里不作赘述。
在步骤204，第二终端接收第一终端发送的待分享数据和待分享数据的分享模式。
第二终端基于步骤203中与第一终端建立数据通信连接，接收并存储第一终端发送的待分享数据和待分享数据的分享模式。
综上所述，根据本实施例的数据分享方法，能够在第一终端与第二终端之间分享数据时不需要耗费双方任何终端的移动数据流量，从而实现在没有网络信号覆盖或网络信号质量较差时，第一终端与第二终端之间仍可进行数据分享。
根据本公开实施例，当分享模式还包括销毁条件时，该方法还可以包括：第二终端确定满足销毁条件时，销毁待分享数据。
关于销毁条件的描述可以参考上述结合图1描述的实施例，这里不作赘述。
根据本公开实施例，当分享模式包括第一传播模式和接收终端标识列表，第一连接请求包括第二终端的标识，且第二终端的标识不属于接收终端标识列表时，该方法还可以包括：第二终端接收第一终端发送的加密指令，并根据加密指令对待分享数据进行加密。
加密指令可以包含第一终端的标识、加密方法等内容。第二终端根据加密指令对待分享数据进行加密可以是第二终端根据第一终端的标识、加密方法、接收到待分享数据的时间等信息进行加密。当分享模式包括接收终端标识列表和第一传播模式，且第一终端确定第二终端的标识不属于接收终端标识列表时，可知第二终端是中间者而不是待分享数据的目的接收方。因此，第二终端根据第一终端发送的加密指令对待分享数据进行加密，使第二终端无法直接查看待分享数据，从而保证待分享数据的安全性和私密性。
根据本公开实施例，当分享模式包括接收终端标识列表和第一传播模式，第一连接请求包括第二终端的标识，且第二终端的标识不属于接收终端标识列表时；或者，当分享模式包括允许第二传播模式时；或者，当分享模式包括接收终端标识列表和第二传播模式，第一连接请求包括第二终端的标识，且第二终端的标识属于接收终端标识列表时，该方法还可以包括：第二终端创建以自身为无线接入点的第三无线局域网；第二终端接收第三终端发送的第二连接请求；以及第二终端基于第二连接请求和/或分享模式确定允许第三终端接收待分 享数据时，第二终端与第三终端建立数据通信连接，并将待分享数据和分享模式向第三终端发送。
当分享模式包括接收终端标识列表和第一传播模式，第一连接请求包括第二终端的标识，且第二终端的标识不属于接收终端标识列表时，表明第二终端不是待分享数据的目的接收方。因此，第二终端需要继续分享待分享数据，以使待分享数据的目的接收方获取到待分享数据。当分享模式包括接收终端标识列表和第二传播模式，第一连接请求包括第二终端的标识，且第二终端的标识属于接收终端标识列表时，表明第二终端是待分享数据的一个目的接收方，因为接收终端标识列表中可能不仅仅包含第二终端的标识，因此，第二终端需要继续分享待分享数据，以使待分享数据的所有目的接收方都获取到待分享数据。当分享模式包括第二传播模式而不包括接收终端标识列表时，表明第二终端是待分享数据的一个目的接收方，因此，第二终端需要继续分享待分享数据，以使尽可能多的终端获取到待分享数据。
第二终端基于第二连接请求和/或分享模式确定是否允许第三终端接收待分享数据的情形与第一终端基于第一连接请求和/或分享模式确定是否允许第二终端接收待分享数据的情形相类似，这里不作赘述。
与第一终端类似，可以预设算法控制第二终端在发送方与接收方之间的切换。当第二终端获取到待分享数据或确定需要进行数据分享时，根据预设算法可自动将第二终端切换为发送方，即，使第二终端创建第二无线局域网；当第二终端分享完待分享数据或者无数据分享时，根据预设算法可自动将第二终端切换为接收方，即，使第二终端搜索可接入的无线局域网，以获取目标数据。
如此，不仅可使待分享数据在设定的分享人群中进行分享，并且还可通过第三方(即中间者)向待分享数据的目的接收方分享待分享数据，或者通过待分享数据的一个目的接收方向另一个目的接收方分享待分享数据，实现数据的快速分享。
图4为根据本公开实施例的第二终端的结构示意图。
如图4所示，根据本公开实施例的第二终端2包括第二搜索单 元20、第二发送单元21、第二处理单元22和第三接收单元23。
第二搜索单元20设置为搜索由第一终端创建的以第一终端为无线接入点的第一无线局域网。第二发送单元21设置为向搜索到的第一终端发送第一连接请求。第二处理单元22设置为在第一终端确定允许第二终端接收待分享数据时，与第一终端建立数据通信连接。第三接收单元23设置为接收第一终端发送的待分享数据和待分享数据的分享模式。
根据本公开实施例，当分享模式包括销毁条件时，第二处理单元22在确定满足销毁条件时，销毁待分享数据。
根据本公开实施例，第三接收单元23接收第一终端发送的加密指令，并且第二处理单元22根据加密指令对待分享数据进行加密。
根据本公开实施例，第二终端2还可以包括第二创建单元24，当分享模式包括接收终端标识列表和第一传播模式，第一连接请求包括第二终端的标识，且第二终端的标识不属于接收终端标识列表时，或者当分享策略包括第二传播模式时，或者当分享策略包括接收终端标识列表和第二传播模式，第一连接请求包括第二终端的标识，且第二终端的标识属于接收终端标识列表时，第二创建单元24创建以第二终端为无线接入点的第三无线局域网。在此情况下，第三接收单元23接收第三终端发送的第二连接请求，第二处理单元22基于第二连接请求和/或分享模式确定允许第三终端接收待分享数据时，与第三终端建立数据通信连接，并且第二发送单元21将待分享数据和分享模式向第三终端发送。
图5为根据本公开实施例的数据分享***的结构示意图。
如图5所示，根据本公开实施例的数据分享***包括第一终端1和第二终端2。
第一终端1设置为获取待分享数据的分享模式并且创建以自身为无线接入点的第一无线局域网。
第二终端2设置为搜索由第一终端1创建的以第一终端1为无线接入点的第一无线局域网，并向搜索到的第一终端1发送第一连接请求。
第一终端1还设置为接收第二终端2发送的第一连接请求，并且基于第一连接请求和/或分享模式确定允许第二终端2接收待分享数据时，与第二终端2建立数据通信连接，并将待分享数据和分享模式向第二终端2发送；
第二终端2还设置为接收第一终端1发送的待分享数据和待分享数据的分享模式。
虽然只示出了一个第二终端2，但是第一终端1也可以接收一个以上第二终端2向第一终端1发送的第一连接请求，也就是说第一终端1可以同时或在一定时间段内接收多个第二终端2发送的第一连接请求。
综上所述，本实施例提供的数据分享***能够在第一终端与第二终端之间分享数据时不需要耗费双方任何终端的移动数据流量，从而实现在没有网络信号覆盖或网络信号质量较差时，第一终端与第二终端之间仍可进行数据分享。
根据本公开实施例，第一终端1还可以获取自身当前所处位置，确定自身当前所处位置属于预先设置的传播区域时，允许第一终端创建以自身为无线接入点的第一无线局域网。
当第一终端1确定有数据需要进行分享时，第一终端1获取自身当前所处位置，并判断自身当前所处位置是否属于预先设置的传播区域，若确定自身当前所处位置属于传播区域，则允许第一终端1创建以自身为无线接入点的第一无线局域网；若确定自身当前所处位置不属于传播区域，则不允许第一终端1创建以自身为无线接入点的第一无线局域网。
由于第一终端1创建的以自身为无线接入点的第一无线局域网的通信距离是有限的，因此通过限定传播区域以使第一终端1确定自身当前所处位置属于传播区域时，才允许第一终端1创建以自身为无线接入点的第一无线局域网，以更好的节省资源并加快数据分享效率。
根据本公开实施例，分享模式还可以包括销毁条件，并且第二终端2在确定满足销毁条件时，销毁待分享数据。
根据本公开实施例，第一终端1向第二终端2发送加密指令， 并且第二终端2接收加密指令，并根据加密指令对待分享数据进行加密。
当分享模式包括接收终端标识列表和第一传播模式，且第一终端1确定第二终端2的标识不属于接收终端标识列表时，第一终端1向第二终端2发送加密指令。第二终端2接收第一终端1发送的加密指令，并根据加密指令对待分享数据进行加密。
当分享模式包括接收终端标识列表和第一传播模式，且第一终端1确定第二终端2的标识不属于接收终端标识列表时，可知第二终端2是中间者而不是待分享数据的目的接收方。因此，第一终端1向第二终端2发送加密指令，以使第二终端2根据加密指令对待分享数据进行加密，使第二终端2无法直接查看待分享数据，从而保证待分享数据的安全性和私密性。
根据本公开实施例的数据分享***还可以包括第三终端3。当分享模式包括接收终端标识列表和第一传播模式，第一连接请求包括第二终端的标识，且第二终端的标识不属于所述接收终端标识列表时；或者，当分享模式包括第二传播模式时；或者，当分享模式包括接收终端标识列表和第二传播模式，第一连接请求包括第二终端的标识，且第二终端的标识属于所述接收终端标识列表时，第二终端2可以创建以自身为无线接入点的第三无线局域网。在此情况下，第三终端3搜索由第二终端创建的以第二终端为无线接入点的第三无线局域网，并向搜索到的第二终端发送第二连接请求。第二终端2接收第三终端发送的第二连接请求，基于第二连接请求和/或分享模式确定允许第三终端接收待分享数据时，与第三终端建立数据通信连接，并将待分享数据和分享模式向所述第三终端发送。第三终端3接收待分享数据和分享模式。
如果第二终端是中间者而不是待分享数据的目的接收方，则第二终端还需先对已加密后的待分享数据进行解密，然后再将待分享数据发送给第三终端。
此外，第一终端1还可作为接收终端。当第一终端1作为接收终端时，还可搜索由第四终端(未在图5中示出)创建的以第四终端 为无线接入点的第二无线局域网，以获取所述第四终端分享的目标数据。
第一终端、第二终端、第三终端只是为了区分不同的终端，以便更清楚的说明技术方案。在实际应用中，第一终端既可以做发送终端，也可以做接收终端，还可以做中转终端，并且第四终端实际上也可以是第二终端。
图6为根据本公开实施例的终端的结构示意图。
如图6所示，根据本公开实施例的终端包括设置模块31、WIFI模块32、连接模块33、保存模块34和查看模块35。
设置模块31的功能之一可以包括设置手机上发送方和接受方的角色转化策略以及设置消息传播启动策略，这两方面的设置是***层面的。默认的启动策略可以包括：当用户设置了要分享的内容后，角色转化策略会向发送方倾斜，当然也会适当切换到接收方，因为有可能其他终端有内容要分享；如果完全没有内容要分享，则一直处于接收方。此外，还有消息层面的设置，例如，设置传播内容的传播区域、传播时间、传播次数、是否允许自动传播、是否允许多点续传以及是否允许借力传播等。
自动传播指的是当用户设置好了需要将内容分享到的群组后，无需用户再次操作，相关的内容就会自动传输出去。
多点续传指的是信息源在最开始只有一个，但是经过一次传输后，信息源就变成了两个，然后信息源就可以呈指数级增长，可以达到迅速在指定的群组里面传播。
借力传播指的是两个人之间相隔较远，无法直接传播，然后可以通过流动的中间者，完成内容分享。
区域传播指的是内容可以限定在某些区域进行传播，通过地理位置限定，这样传播内容更加精准。
WIFI模块32主要有两个方面的作用，即，作为热点提供方或者作为对热点进行搜索的寻找方。定位***需要至少两个终端参与，一个终端作为热点提供方(即，被寻找的终端)，另外一个终端作为寻找方。热点提供方在满足预先设置的条件时，自动启动特殊的热点， 并等待寻找方来寻找。另一方面，当用户寻找热点时，可以启动作为寻找方终端，自动搜索符合需要的热点，并自动连接。
连接模块33主要用于建立两个终端之间的握手连接。根据本公开实施例，可以支持各种用于在两个终端之间进行连接的握手协议。
保存模块34用于在接收模式下，将接收到的信息保存，接收到的信息可以携带各种控制信息(比如，生命周期、秘钥等)。此外，保存的内容只能通过特定的查看工具(例如，查看模块35)才能查看。
查看模块35用于查看保存的内容。由于只能利用特定的查看工具来查看保存的内容，从而保证了安全性。
下面通过三个具体的应用场景来说明利用根据本公开实施例的终端进行数据分享的过程。
第一应用场景：家人之间分享照片
一家六口人(包括爷爷、奶奶、父亲、母亲、儿子和女儿)设置为一个家庭群组，然后该群组分享内容的方式可以包括：内部传播(不借道传播)、指定区域传播(仅限指定的几个地方传播)、允许多点续传(接受方也可以再次将内容发送出去)以及允许查看。
父亲出去旅游，用手机拍摄了若干照片，并且设置将照片分享到这个家庭群组，然后就不用再进行操作了。
父亲的手机判断当前所处区域，如果当前区域不属于分享区域，则不会启动将照片分享至家庭群组的操作。
奶奶在家带女儿，用手机拍了几张关于女儿的照片，并且设置将照片分享到这个家庭群组。由于奶奶的手机所处的区域属于允许分享的区域，奶奶的手机会按照一定的频率在发送方和接受方进行切换。为了避免耗电，可以在一定时间内(例如，十分钟)在没有发现其他的发送方和/或接收方的情况下，暂时停止切换。
当妈妈下班回家后，妈妈的手机检测到进入为家庭群组设置的传播区域时，由于妈妈的手机上没有要分享的内容，则会自动进入接收模式作为接收方。由于奶奶的手机上有内容要分享，当奶奶的手机进入发送模式作为发送方时，奶奶的手机可以创建热点，并等待妈妈 的手机连接至该热点。
妈妈的手机和奶奶的手机自动进行连接，随后奶奶的手机上设置的分享内容自动传输给妈妈。
随后，儿子和爷爷又一起回家，他们可以分别从奶奶的手机和妈妈的手机上获取分享的内容。获取分享内容的过程与妈妈的手机从奶奶的手机上获取分享内容的过程基本上一致。
然后父亲回到家，所有的人都有内容要分享，母亲、奶奶、爷爷和儿子所分享的内容是一致的，在他们之间握手的可以知道这个信息，因而不会重复获取。父亲可以作为发送方也可作为接受方，将内容分享给其他人，也可以从其他任何一个人获取内容，从而全部内容的分享。
如果有邻居过来，由于邻居不在家庭群组内，因此分享的内容不会传播给他。
当家庭群组内成员的内容都达成一致后，父亲的手机会自动停止分享，奶奶的手机也会停止分享。当仅差一个成员没有成功获取内容或者是共享的时间超过一定的时长后，也可以提示是否需要停止内容的分享。
第二应用场景：好友之间分享消息
假设甲、乙、丙、丁四个人好友同在一个学校，并且分别在不同的班级，他们成为一个好友群组。分享规则可以包括：允许借力传播、指定人可以查看、查看方式是查看后销毁并且时效是半天(即，在中间者的手机上保留消息的时间为半天)。
甲分享一个消息到好友群组，此时甲的手机进入发送模式(即，作为发送方)，并创建热点，等待中间者或者是目标人的连接至该热点。
甲的同学A的手机设置了允许借道传播，在某个时间周期搜索到甲的手机建立的热点，随后与甲的手机建立连接，并成功获取到甲分享的消息。由于A只是一个中间者，因此会根据原始发送者甲的一些信息(比如手机型号、手机号码和发送时间等)生成一个秘钥并对A接受到的消息进行加密，然后将加密后的消息保存到手机中，此时 A不能查看该消息。
A到操场运动并遇到B。类似于甲将消息传递给A的方式，A可以将甲分享的消息传递给B，例如，A的手机通过对加密的保存消息进行解密，以还原成原始消息后传输给B的手机。然后，根据原始传输方甲以及A的一些信息生成一个新的秘钥并对消息进行加密，加密后的消息后保存B的手机上。
B回到教室，由于B和乙在同一个班级，并且乙为目标接受者之一，因此B的手机建立热点，等待乙的手机连上该热点后，乙可以从B的手机获取甲分享的消息。由于乙是目标接受者之一，因此不对通过B的手机发送的消息进行加密，使得乙可以查看消息。
经过了半天时间，A和B(以及其可能的中间者)的手机上保存的加密后的消息被销毁，以保证安全性。
第三应用场景：商场寻人
假设甲在某商场丢失了小孩，并迅速通过手机发送了一条求助信息并附带了一张小孩的照片，同时还可指定有偿传播和/或信誉传播。有偿传播是指协助传播的中间者可以得到报偿。信誉传播是指，如果传播者的信誉越好，其发送的传播信息被优先处理的可能性就越大。
乙就在甲附近，并且乙的手机允许接受这种传播方式的信息，然后乙可以将收到的消息多次传播出去。
以此方式，可以将丢失孩子的消息以及孩子的照片迅速地传播给商场内的很人，以便有助于快速找到丢失的孩子。协助传递的中间者可以获得相应的奖励。
综上所述，根据本实施例提供的终端(例如手机)进行数据分享时，内容的传播是通过组建局域网方式进行的，每个终端既可以做发送方又可以做接收方，同时对于在发送方和接收方之间进行切换的频率进行控制。当终端作为发送方时会创建热点，而处于接收方的终端会自动搜索热点并进行连接。在连接上热点后，可以通过TCP握手完成通信连接，并通过Socket连接传输内容。根据本实施例的终端进行数据分享时，可以避免因无网络信号或网络信号质量较差等限制 条件造成的无法进行数据分享，并且可以具有自动传播、多点续传、借力传播、区域传播等多种特性，提高了数据分享效率。
本公开实施例提供的数据分享方法、终端及***，能够快速实现终端之间的数据分享且不需要消耗移动数据流量，弥补了相关技术中数据分享的不足之处，并丰富了数据分享的方式。
此外，能够实现在终端没有网络信号覆盖或网络信号质量较差时，终端之间仍可进行数据分享；能够使数据在设定的分享区域或分享人群中进行分享，并且还可通过第三方向接收方分享数据、或通过一个接收方向另一个接收方分享数据，从而加快数据分享效率。
以上公开的内容仅为本公开的实施例，而并非用于限定本公开的保护范围。凡在本公开的精神和范围之内所作的任何修改、等同替换和改进等，均包含在本公开的保护范围之内。
