以数字生活网络联盟(Digital Living Network Alliance，DLNA)为例，假设用户在播放设备上操作，发现并获取源设备上共享的媒体资源并在播放设备上播放，具体过程如下：
用户打开DLNA的应用程序，点击“周边设备”按钮，搜索处于同一局域网的源设备；
系统将搜索到的周边的所有源设备显示给用户，用户从周边设备列表中选择所需要的设备，假设一共搜索出2台周边设备，用户点击选择设备标识为“[Mobile]GT-N7000”的源设备；
系统将源设备“[Mobile]GT-N7000”所共享的媒体内容列表展示给用户；
用户从媒体内容列表中选择想要播放的媒体内容，假设用户点击选择了媒体名称为“GALAXY_Note_Tutorial”的媒体内容；
播放设备播放名称为“GALAXY_Note_Tutorial”的媒体内容。
该媒体内容共享过程中操作步骤较多，从开始到最后播放需要经历5个操作步骤，其中4个步骤需要用户手动选择，操作起来很繁琐。
并且，媒体共享的应用程序，系统默认的设备标识一般为设备型号、设 备通用唯一识别码(Universally Unique Identifier，UUID)、设备互联网协议(Internet Protocol，IP)地址和设备介质访问控制(Media Access Control，MAC)地址，这些设备标识对于用户而言就是一串数字或者字符，用户很难读懂并与实体物理设备匹配，增加了用户选择设备的难度。用户可以为设备设置易于识别的别名，该设置过程同样较为繁琐。
另外，系统通过设备型号来标识设备，如果局域网中有两台相同型号的设备，则用户将难以区分两个设备。
综上可知，现有的媒体共享方式操作繁琐，用户体验差。

当源设备共享媒体内容时，需要提供共享媒体内容的内容列表，以便用户选择所要播放的媒体内容。
播放设备是媒体共享应用场景中媒体内容的接收者，能够播放所选定的共享媒体内容。通常具有网络连接功能和播放能力的家庭网络设备都可以作为源设备，例如智能手机、平板电脑、电视、音响、数字多功能光盘(DVD)播放机等。
播放设备可以发现接入同一局域网络的源设备，并且可以从源设备或者 根据源设备提供的媒体地址信息获取所要播放的媒体内容并且在本地播放。
本发明实施的一个典型应用场景为家庭网络，在家庭网络环境下具有多种类型的移动电子设备，这些移动电子设备均可连入家庭网络，一部分移动电子设备具有存储功能，可存储一定数量的媒体文件并共享到家庭网络之中，可作为源设备；一部分移动电子设备具有媒体的播放能力，能够播放诸如音乐、电影等媒体内容，可作为为播放设备。
另外一种典型应用场景就是好友之间的互相共享，例如去好友家访问，在好友家的家庭网络中想要分享其共享的媒体内容，或者几个好友在外面共同接入同一个无线局域网(Wireless Local Area Network，WLAN)中进行媒体内容的相互共享，这种情况属于临时搭建的媒体共享网络，需要一种方便快捷、符合用户操作习惯的设备选定的方式。
本发明第一实施例中，如图1所示，位于同一局域网中的源设备和播放设备进行媒体资源共享的详细方法流程如下：

本发明实施例中，第一验证信息和第二验证信息可以有多种生成方式，包括但不限于以下几种：
第一种，第一验证信息由源设备根据采集到的用户输入的声音信息生成，第二验证信息由播放设备根据采集到的用户输入的声音信息生成。具体地，源设备采集到用户发出的语音信号，从语音信号中提取出声纹特征数据，将提取到的声纹特征数据作为第一验证信息，同样地，播放设备采集到用户发出的语音信号，从语音信号中提取出声纹特征数据，将提取到的声纹特征数据作为第二验证信息。
第二种，第一验证信息由源设备根据采集到的屏幕上的滑动轨迹生成，第二验证信息由播放设备根据采集到的屏幕上的滑动轨迹生成。优选地，该滑动轨迹包括组成的图案(如圆形、方形、三角形、心形以及其他不规则图案)和滑动向量(如向左、向右、向上、向下、顺时针、逆时针等)，但不包括滑动轨迹在设备屏幕上的起始位置和终止位置。
第三种，第一验证信息由源设备根据采集到的用户在屏幕的第一位置的触摸操作生成，第二验证信息由所述播放设备根据用户在屏幕的第二位置的触摸操作生成，具体实施中，触摸操作可以为点击操作、长按操作、滑动操作等。
第四种，第一验证信息由源设备根据采集到的指纹图像生成，第二验证信息由播放设备根据采集到的指纹图像生成。
优选地，若第一验证信息、第二验证信息为通过采集用户的指纹图像生成，则源设备根据用户操作生成第一验证信息，包括但不限于以下几种实现方式：
第一种，源设备采集用户输入的指纹图像，对该指纹图像进行方向场校正后，在校正后的指纹图像的全部或约定的子区域提取指纹局部特征点，根据提取到的指纹局部特征点生成第一验证信息；
第二种，源设备采集用户输入的指纹图像，对该指纹图像进行方向场校正后，在校正后的指纹图像中的至少一个子区域提取指纹局部特征点，根据提取到的指纹局部特征点生成第一验证信息，并在配对请求消息中携带该至少一个子区域的位置信息；

相应地，播放设备根据用户操作生成第二验证信息，包括但不限于以下几种实现方式：
第一种，相应于第一验证信息生成方式中的第一种，播放设备采集用户输入的指纹图像，对该指纹图像进行方向场校正后，在校正后的指纹图像中的约定的子区域提取指纹局部特征点，根据提取到的所有或部分指纹局部特征点生成第二验证信息；
第二种，相应于第一验证信息生成方式中的第二种，配对请求消息中携带源设备生成的第一验证信息所对应的指纹图像的子区域的位置信息，播放设备采集用户输入的指纹图像并对采集到的该指纹图像进行方向场校正后，以及接收源设备发送的该配对请求消息后，在校正后的指纹图像中该配对请求消息中携带的该子区域的位置信息确定的子区域提取指纹局部特征点，根据提取到的所有或部分指纹局部特征点生成第二验证信息；
第三种，相应于第一验证信息生成方式中的第三种，播放设备采集用户输入的指纹图像，对该指纹图像进行方向场校正后，在校正后的指纹图像中的至少一个子区域提取指纹局部特征点，根据提取到的所有或部分指纹局部特征点生成第二验证信息，并在配对通知消息中携带该至少一个子区域的位置信息。
该优先地实施方式中，第二验证信息能够起到匹配识别的作用，即能够 通过比较第一验证信息和第二验证信息识别出前后两次采集的指纹是否来自同一用户的同一手指，且第二验证信息中未携带任何与用户指纹相关的身份信息，即使第三方获取用户的第二验证信息，也不能利用该第二验证信息进行用户身份的验证，同时第三方也不能通过多次获取一个用户的第二验证信息来获取用户所有的指纹特征信息。
本发明实施例中，源设备比较第一验证信息与第二验证信息，确定第一验证信息与第二验证信息相同，或者第二验证信息包含于第一验证信息，或者第二验证信息与第一验证信息的相似度达到设定阈值，或者第二验证信息中包含且第一验证信息也包含的特征占第二验证信息总特征的比值超过设定阈值，则确定第一验证信息与第二验证信息匹配。
例如，源设备采集到的滑动轨迹为三角形，第一验证信息为三角形，若播放设备采集到的滑动轨迹也为三角形，即第二验证信息也为三角形，则确定源设备与播放设备匹配。
又例如，源设备采集到的第一声音信息，第一验证信息为该第一声音信息，播放设备采集到的第二验证信息为第二声音信息，该第一声音信息与第二声音信息的相似度高于设定阈值，则确定源设备与播放设备匹配，具体可以为识别出的声音信息的内容匹配，也可以是识别出的声音信息中的音色匹配等。
又例如，源设备采集到用户在第一位置的三连击操作，第一验证信息为三连击操作，播放设备采集到用户在第二位置的三连击操作，第二验证信息也为三连击操作，可确定第一验证信息与第二验证信息匹配。
优选地，源设备比较第二验证信息与第一验证信息，确定第二验证信息中的每个指纹局部特征点均在第一验证信息中有对应的指纹局部特征点，确定源设备与播放设备配对成功；
或者，源设备确定第二验证信息中在第一验证信息中有对应的指纹局部特征点的个数占第二验证信息中的指纹局部特征点总数的比例超过设定阈值，确定源设备与播放设备配对成功。
本发明实施例中，播放设备的标识可以是任何能够唯一确定播放设备身份的标识信息，例如，播放设备的UUID、设备序列号、IP地址、MAC地址等可以表征设备身份的数字序列或者字符串等。
同样地，源设备的标识可以是任何能够唯一确定源设备身份的标识信息，例如，源设备的UUID、设备序列号、IP地址、MAC地址等可以表征设备身份的数字序列或者字符串等。
本发明实施例中，若源设备本地保存有用户选择的媒体资源的内容，直接将用户选择的媒体资源发送给播放设备进行播放；若源设备本地并未保存用户选择的媒体资源的内容，将用户选择的媒体资源的地址信息发送给播放设备，由播放设备根据该地址信息从网络或其他存储设备获取媒体资源并播放。
本发明第一实施例中，源设备根据用户操作生成第一验证信息，播放设备根据用户操作生成第二验证信息，源设备将播放设备发送的第二验证信息与自身生成的第一验证信息进行比对，确定该源设备与该播放设备匹配后，将共享的媒体资源或媒体资源的地址信息发送给播放设备，只需要用户分别在共享媒体资源的播放设备和源设备上进行一次操作即可完成媒体资源共享过程，简化了媒体资源共享的过程中用户操作的次数，降低了媒体资源共享的操作难度。
以下通过两个具体实施例对本发明第一实施例源设备验证源设备与播放设备相匹配后发送共享的媒体资源给播放设备进行播放的具体过程进行说明。
第一具体实施例中，如图2所示，进行媒体资源共享的详细过程如下：
步骤201：源设备和播放设备相互发现。
在诸如DLNA、Airplay、Miracast和Airdrop等家庭网络媒体资源共享解决方案中都涉及源设备和播放设备的相互发现和连接的建立，这是完成媒体资源共享的第一步。不同的解决方案中设备和服务发现的机制不尽相同，例如DLNA设备采用的是简单服务发现协议(Simple Service Discovery Protocol， SSDP)协议来实现，而Airplay设备采用的是多播域名系统(Multicast Domain Name System,MDNS)协议来实现，还有一些其他的媒体共享解决方案是采用自己开发的私有设备和服务发现机制来实现。
当源设备或者播放设备接入家庭网络或者其他类型的局域网，会通过协议规定或者预先约定的多播地址和端口向整个局域网络周期性地发送多播消息，所述多播消息中会携带有发送设备的设备和服务发现信息，包括设备型号、设备网络协议(IP)地址、设备类型(源设备或播放设备)、设备UUID等设备信息以及该设备所支持的服务标识、服务访问统一资源定位符(Universal Resource Locator，URL)等服务信息。
接入在同一局域网络的其他移动电子设备都会接收到该多播消息，从而获取了发送该多播消息的移动电子设备的设备和服务发现信息，发送多播消息的移动电子设备被其他的移动电子设备所发现。
步骤202：播放设备采集用户触摸播放设备的屏幕或者指纹采集区域输入的指纹图像。
该具体实施方式中，播放设备所对应的移动电子设备是一台具有指纹采集功能的设备。指纹采集方式由移动电子设备具体的功能配置决定，有的移动电子设备可以实现全屏采集指纹，即移动电子设备均在用户点击触摸屏幕的任何区域时均可采集到指纹图像；有的移动电子设备可以实现屏幕部分区域采集指纹，移动电子设备在用户点击触摸屏幕的一部分区域时采集到指纹图像；而有的移动电子设备只能在固定的区域(如Home键)上点击或者触摸才能采集到留下的指纹图像。
当用户在播放设备上点击或者触摸屏幕或者触摸指纹采集区域，播放设备上的指纹采集器就能通过光学、热敏或者生物射频等方式采集到用户的指纹。
步骤203：播放设备对采集到的指纹图像进行处理，生成第二验证信息。
具体地，如图3所示，第二验证信息的生成过程如下：
S301：确定指纹图像的方向场。
本发明实施例中，播放设备中的指纹采集装置在采集指纹图像时并不限定用户的手指按压方向，用户可在屏幕或者其他指定的指纹采集区域内在任何方向上按压手指输入指纹图像。
播放设备所采集到的指纹图像是由中心花纹、脊线和谷线构成的，这些线条纹理具有一定的走势和形状，它们所表现出来的方向性即为指纹图像的方向场。指纹的方向场是对纹线形状的拓扑结构的一种描述，表征了指纹纹线的走势方向。指纹图像的方向场可以采用掩膜法和公式法计算得到。
S302：计算出指纹图像的方向场后对方向场进行校正。
具体地，对指纹图像进行旋转，使得旋转后的指纹图像的方向场方向与预设的轴线方向平行，以保证在播放设备和源设备上采集的指纹图像的方向场方向一致。
S303：对方向场校正后的指纹图像进行等比例分割，将完整的指纹图像等比例地分割成若干个指纹子图像。
本发明实施例中，通过在第二验证信息中携带部分指纹特征信息，保证第二验证信息中不携带任何与用户指纹相关的用户身份信息，即禁止在第二验证信息中携带指纹图像中的所有指纹特征信息。
其中，每个指纹子图像的尺寸相同。
S304：随机抽取多个不同位置的指纹子图像，提取所选取的多个指纹子图像中的指纹局部特征点。
人类的指纹特征由总体特征和局部特征构成，其中局部特征点包括终结点、分叉点、分歧点、孤立点、环点和短纹六种类型，一个完整的指纹大约有100个局部特征点，对于每一个局部特征点通过类型、水平位置、垂直位置、方向、曲率和质量这6个信息维度来描述，这些局部特征点的特征信息都是终身不变的。
如图4所示，系统从分割之后的指纹子图像中随机选取了2个指纹子图像，其中位于左边的记为指纹子图像A，位于右边的记为指纹子图像B，这两个指纹子图像具有相同的尺寸(即长和宽具有相同的像素点数量)。指纹子图 像A中包含有6个指纹局部特征点，编号为1-6；指纹子图像B中包含有5个指纹局部特征点，编号为7-11。提取出这两个指纹子图像中的指纹局部特征点后针对每个指纹子图像生成特征点列表，在特征点列表中的每个局部特征点都包含该特征点的类型、水平位置、垂直位置、方向、曲率和质量这6个描述信息，其中水平位置和垂直位置指的是该指纹局部特征点在所在的指纹子图像中的相对位置，而不是在整个指纹图像中的绝对位置。
需要注意的是，在随机抽取指纹子图像时应尽量不选取指纹图像的边缘区域，因为该区域的指纹图像分辨率较低，不利于后期的特征提取和验证匹配。
S305:选取部分局部特征点，生成第二验证信息。
S304中随机抽取了指纹子图像A和指纹子图像B，并从指纹子图像A中提取出了6个指纹局部特征点和从指纹子图像B中提取出了5个指纹局部特征点。从每个指纹子图像中都随机抽取一部分指纹局部特征点，组成一个混合的指纹局部特征点列表。
在本发明实施例中，分别从指纹子图像A和指纹子图像B中选取了编号为1,3,4,7,9,11这6个指纹局部特征点生成第二验证信息，其中1,3,4属于指纹子图像A中的指纹局部特征点，而7,9,11属于指纹子图像B中的指纹局部特征点。由于第二验证信息中包含有多个指纹子图像的部分指纹局部特征点的特征信息，而这些指纹子图像的位置不同，因此第二验证信息中给出的指纹局部特征与用户指纹图像中的任何一块区域的指纹局部特征均不能匹配，即使第二验证数据被第三方获取到，第三方也无法利用第二验证信息进行任何与用户身份识别和验证的操作，同时第三方也不能通过反复获取第二验证信息的方式获取用户的全部指纹特征信息。
步骤204：播放设备通过多播形式发送多播事件消息给接入同一局域网的所有源设备，该多播事件消息中除了包含有第二验证信息，也包含播放设备的IP地址、设备UUID、访问地址URL等信息，以便源设备在接收到多播事件消息时能够确定发出该消息的播放设备。
当播放设备生成了第二验证信息时，即意味着完成了媒体资源共享中播放设备的选定。播放设备向通过接入的局域网广播多播事件消息，网络中所有的源设备都可接收到该多播事件消息。
步骤205：用户在自己选择的源设备上选择共享的媒体资源，在用户选择媒体资源的同时，源设备采集用户输入的指纹图像。
用户选择一个源设备，此时源设备上展示着共享的媒体资源列表。用户点击源设备的触摸屏幕，选择共享的媒体资源，完成媒体资源的选定。同时，由于在选择共享的媒体资源的时候触摸了显示屏，在显示屏上留下了指纹，因此源设备可以同时采集用户的指纹图像。
步骤206：源设备对采集到的指纹图像进行处理，生成第一验证信息。
具体地，源设备确定采集到的指纹图像的方向场，并对方向场进行校正，使在源设备采集的指纹图像与预设的轴线方向平行，以保证在播放设备和源设备上采集的指纹图像的方向场方向一致。源设备对校正后的指纹图像进行等比例缩放，使其与播放设备上采集的指纹图像的尺寸相同，根据接收到的第二验证信息中携带的提取局部特征点的指纹子图像的位置和尺寸信息，在源设备采集的指纹图像的相同的位置提取尺寸相同的指纹子图像。源设备在所提取的每个指纹子图像提取指纹局部特征点，对提取到的所有指纹局部特征点的特征信息进行汇总，生成第一验证信息。
生成第一验证信息的具体方法可参见上述S301至S305的描述。
步骤207：源设备对比第一验证信息和第二验证信息，验证在播放设备和源设备上的两次采集的指纹是否匹配。
源设备接收的第二验证信息中包含两个指纹子图像中的部分指纹局部特征点的特征信息，源设备生成的第二验证信息中包含了与两个指纹子图像位置相同的指纹子图像中所有指纹局部特征点的特征信息。对第二验证信息中的每个指纹局部特征点的特征信息进行比对，比对在第一验证信息中是否有对应的指纹局部特征点，针对每个指纹局部特征点要比对指纹特征信息中的类型、水平位置、垂直位置、方向、曲率和质量这6个描述维度，如果特征信 息一致，则该指纹局部特征点在第一验证信息中有匹配的指纹局部特征点，比对通过，否则该指纹局部特征点比对不通过。
在对第二验证信息与第一验证信息是否匹配的判决上，通常设置一定的阈值，即如果第二验证信息中通过比对的指纹局部特征点的个数或者通过比对的指纹局部特征点个数占第二验证信息中的指纹局部特征点总数的比例超过某一阈值，则判决为第二验证信息与第一验证信息匹配，即在播放设备和源设备上两侧采集的指纹为同一用户的指纹；否则，则判决为第二验证信息与第一验证信息不匹配。
该具体实施例中，第二验证信息中包含了6个指纹局部特征点，而第一验证信息中包含了11个指纹局部特征点。分别将第一验证信息中的6个指纹局部特征点依次与第二验证信息中的11个指纹局部特征点的特征信息比对，第二验证信息中比对通过的指纹局部特征点的个数大于或者等于阈值4，则确定匹配通过。阈值根据具体的情况和用户的实际需求预先设定，阈值设置的越大，安全性越高，计算量越大，响应时间较长；阈值设置的越小，响应时间越短，安全性越低。
步骤208：若匹配通过，则源设备直接将用户选择共享的媒体资源的地址信息发送给播放设备，播放设备根据该地址信息获取媒体内容并在播放设备上播放。
若匹配通过，则源设备直接向选定的播放设备发送请求播放命令，该请求播放命令中包含有用户选择共享的媒体资源的地址信息(URL)，播放设备接收到该请求播放命令后根据该地址信息向源设备或者存储有该媒体资源的内容的服务器发送请求，所接收的相应消息即为该媒体资源的内容的媒体流，播放设备就可以播放该内容。整个过程用户是无需参与的。
第二具体实施例中，如图5所示，进行媒体资源共享的详细过程如下：
步骤501：源设备和播放设备相互发现。
具体过程参见第一具体实施例中步骤201的描述，此处不再赘述。
步骤502：用户触摸源设备的触控屏幕，选择共享的媒体资源，源设备采 集用户触摸屏幕时输入的指纹图像，并确定用户选择共享的媒体资源。
步骤503：源设备对指纹图像进行处理，生成第一验证信息。
具体过程与第一具体实施例中生成第一验证信息的描述大致相同，不同之处在于：假设采集到的指纹图像经过方向场校正和等比例分割后随机抽取2个指纹子图像，记为指纹子图像C和指纹子图像D，在这2个指纹子图像中提取指纹局部特征点，假定在指纹子图像C中提取出8个指纹局部特征点，在指纹子图像D中提取出6个指纹局部特征点，则生成的第一验证信息中包含指纹子图像C和指纹子图像D中提取到的所有14个指纹局部特征点的特征信息。
步骤504：源设备向所接入的局域网中所有的播放设备发送配对请求消息。
该配对请求消息中携带源设备的地址信息。
在源设备生成第一验证信息之后，源设备就会向接入同一局域网中的所有播放设备发送配对请求消息，该配对请求中包含有源设备随机抽取的指纹子图像的数量以及每个指纹子图像的位置信息，以便播放设备在采集到用户指纹图像后能够根据获得相同位置上的指纹子图像。对于发送的配对请求消息，源设备会设置一个等待时间阈值，如果在发出配对请求之后在等待时间阈值范围之内没有接收到播放设备发回的响应报文，则自动认为该请求失效，源设备与该配对请求对应的播放设备没有建立配对关系。
步骤505：用户在其所选定的播放设备上触摸屏幕，播放设备采集用户的指纹图像，对指纹图像进行处理，生成第二验证信息。
具体地，播放设备确定采集到的指纹图像的方向场，并对方向场进行校正，使在源设备采集的指纹图像与在播放设备采集的指纹图像的方向场方向一致，对校正后的指纹图像进行等比例缩放，使其与源设备上采集的指纹图像的尺寸相同。然后根据接收到的配对请求消息中所携带的指纹子图像的数量、位置和尺寸信息在播放设备采集的指纹图像中的相同的位置上提取尺寸相同的指纹子图像。播放设备在提取的每个指纹子图像中提取指纹局部特征点，从提取的每个指纹子图像中的指纹局部特征点中随机抽取部分指纹局部 特征点，将抽取到的部分指纹局部特征点的特征信息进行汇总，生成第二验证信息。
该具体实施例中，播放设备根据配对请求消息中携带的指纹子图像的数量、位置和尺寸信息，在播放设备采集的指纹图像中对应位置提取2个指纹子图像记为指纹子图像C和指纹子图像D，并在这2个指纹子图像中提取出14个指纹局部特征点，其中，指纹子图像C中提取到8个指纹局部特征点，指纹子图像D中提取到6个指纹局部特征点，在指纹子图像C中的8个指纹局部特征点中随机抽取5个特征点，在指纹子图像D中的6个指纹局部特征点中随机抽取4个特征点，总共抽取的9个特征点的特征信息进行汇总，生成第二验证信息。
步骤506：播放设备将第二验证信息加载到配对请求消息的响应报文(即配对响应消息)中发送给源设备。该配对响应消息中还携带播放设备的地址信息。
步骤507：源设备对第一验证信息和第二验证信息进行匹配，验证在播放设备和源设备上的两次采集的指纹是否为同一个。
具体过程参见第一具体实施例中的步骤207。
步骤508：若匹配通过，则源设备直接将用户选择共享的媒体资源的URL发送给播放设备，以便播放设备根据该URL信息获取媒体资源的内容并在播放设备上播放。
具体过程参见第一具体实施例中的步骤208。
基于同一发明构思，本发明第二实施例中，如图6所示，进行媒体资源共享的详细方法流程如下：
