Description

触控屏解锁方法、装置及电子设备、显示器及移动终端 技术领域
本申请涉及电子设备的操控技术，尤其涉及一种基于手势解锁的触控屏解锁方法、装置及电子设备、触控显示器及移动终端。
背景技术
近些年来，移动设备(如智能手机、平板电脑等)的应用越来越广，功能越来越丰富，用户存放的隐私信息也越来越多，这对移动设备的性能提出了更高的要求。目前的移动设备一般采用触控屏作为显示模块和用户输入设备，为了防止用户隐私被他人窥窃，通常会使用特定的加解密工具来进行锁屏或者锁定特定的应用。当满足锁定条件时，在经过空闲时间后的移动设备、触控屏或运行在移动设备上的应用将被锁定。当用户输入密码时，移动设备、触控屏或运行在移动设备上的应用可相应地解锁。
目前的主流移动设备多主要采用字符串密码、九宫格手势密码、人脸识别、指纹识别等方式来进行加解密。上述密码系统中，考虑到产品的可靠性和部署成本要求，人脸识别和指纹识别难以成为企业及用户的首选，因此产品中使用较多的是前两种密码，即字符串密码和九宫格手势密码。对于字符串密码而言，一般需要输入四位数字PIN，其模式比较单一，且还存在输入不太方便的问题。对于九宫格手势密码而言，它将9个点按照3×3的方式均匀分布在触控屏上的某个正方形区域内，加密方法时按一定顺序连接若干个点作为密码，解密时如果能够按照正确顺序连接这些点则解密成功，失败的话则将继续保持在锁定状态。这种九宫格手势密码通过简单地连接9个固定点来确定加密手势和解密手势，这些点之间的组合关系较为有限，因而不仅同样存在模式单一的问题，而且存在因解密难度小的安全性问题。

具体实施方式
针对目前移动设备等电子产品密码形式比较单一，尤其是字符串和九宫格手势密码的密码形式单一问题，本申请的以下实施例提供一种使用方便、变化丰富、可定制和可靠的密码体系。
这种密码体系关注以下方面：(1)基于自然图片进行热区选取(可手动选取或者利用特定算法自动选取)，然后定义各种类型解锁规则，得到一套密码流程框架；(2)基于热区之间语义关系来确定加密手势，以获得适当的加密方法，如将热区 进行分组，然后将组内的热区连接的方法；或者选择一个中心热区，再把其他热区都与之连接的方法等。
该密码体系是实质上是一种基于图片分析的手势解密方案，其采用自然图片为基础，可在用户选择的特定图片上利用模式识别和计算机图形学技术，提取突出目标(例如人脸或景物区域)作为用户点击热区，然后由用户确定的特定加解密规则来点击或者滑动进行解锁，最终实现加解密方式的多样性，同时也有助于提升设备的安全性。
这种基于图片分析的密码锁方案可方便地适用具有触控屏的电子设备，产品形式多种多样，它们可以是移动终端(如智能手机、平板电脑等)，也可以是具有某种处理功能的单一触控显示器(触摸屏)。关于这些电子设备的具体物理结构及工作原理非本申请发明点所在，故在此不展开说明，具体可参考习知的现有技术文献。
以下着重对本申请的触控屏的手势解锁方法及装置进行描述，如下文中描述电子设备、触控显示器及移动终端时关于相应的加密解密过程的内容有不详尽指出，请参见触控屏的手势解锁方法及装置部分描述的内容。
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施例的限制。
参见图1，其示出根据本申请一个触控屏的手势解锁方法实施例。该实施例描述了一种基于图片分析的手势解锁方案，具体包括S110～S140等步骤，进一步详细描述如下：
该方法始于步骤S110，其在触控屏处于锁定状态下，展现预设的密码图片。其中的密码图片具有可用于设定加密手势的多个热区(热点)，设定好加密手势后可存在与产品的存储器中。在锁定状态下调取该密码图片后，就可通过比对解密手势(即预先设定的手势)与加密手势(即当前的操作手势)是否一致来对触控屏进行 解锁。可以理解的是，本实施例中创建的密码图片可以不止一个，但在解锁时提供一个密码图片解锁即可。当然，本申请可以按预设周期(如1个月、半年等)动态地提示重置密码图片、密码图片上的热区、以及与热区相关的加密手势，通过这种方式提示重新加密，使得有关产品使用起来更为安全，也更为方便。
如步骤S120所示，在锁定状态下若发生触控事件(如点击、划拉触控屏)时，会相应检测触控屏的触控事件，根据这些触控事件可以获得与热区相关的解密手势。这些解密手势是否正确，将关系到是否能顺利地将触控屏解锁。一般地，此处的解锁手势包括点击、滑行等，其中点击一般用于处理单点式密码的操作，而滑行可用于处理序列关系式密码的操作。
按照步骤S120得到解密手势后，需进一步按步骤S130来识别解锁手势是否正确。具体是将解密手势与加密手势相比较，以判断解密手势与加密手势是否匹配(通常指两者一致)。如正确的话，则可进入步骤S140进行解锁；否则的话，将返回到步骤S120来继续捕捉解密手势，此时的触控屏会继续保持在锁定状态。
在步骤S140中，将根据步骤S130的识别结果来控制转换锁定/解锁状态。在识别解密手势与加密手势相匹配时，将触控屏切换到解锁状态。在进入到触控屏的解锁状态后，由此可进入用户界面进行正常的操作，具体不再赘述。
一般而言，图1所示的触摸屏的解锁过程可以进行一些限制或提示。此处，手势锁定或手势解锁的状态可进一步监控如下：当解密手势的当前触控位置位于热区之内时，将手势解锁被激活，这时按照图1所示流程尝试解锁即可。在手势解锁被激活后，如果操作失误或者进行非法解锁，将释放手势解锁过程，此时将无法按照图1解锁成功。
释放手势解锁的情形有多种，例如：解密手势的当前触控位置位于热区之外；解密手势的操作次数超过预设次数阈值；解密手势的操作时间超过预设时间阈值；等等。当然，也可以出现上述多种情形，此时手势解锁显然也将被释放。手势解锁 释放后，先前获得的解密手势被重置，此时需要重新操作。可以理解的是，甚至在某些特殊情况下，手势解锁释放状态下也可以将触控屏锁死而不能再次进行解锁，这种情形下需通过重新设置ROOT引擎等方式才能解锁。
可以理解的是，手势解锁被激活/释放时，可以相应地展现解锁激活/释放提示信息，例如，可以使热区变光或变色，也可以显示光标、字标或图标等信息来展现解锁激活/释放提示信息，这种提示信息便捷、迅速。当然也可以采用其他方式提示解锁激活或解锁释放状态，例如在热区外环绕边框、热区进行闪动等等，不再赘述。
图1所示实施例的触控屏手势解锁方法体现的是一种基于图片分析的密码系统，其需要预先设定密码图片及加密手势，主要包括两个方面的内容：一方面是，选择密码图片并提取图片上的热区；另一面是，根据热区设置规则来确定加密手势(密码)。为了对本申请的加密过程有更深刻的认识，以下进一步结合图2来进行充分描述。
参见图2，示出适应于图1中触控屏手势解锁方法锁使用的密码图片的加密过程，具体包括以下S210～S240等步骤：
在步骤S210中，加密过程需要由用户选择图片。这些图片可以是存储于设备上的已有图片，也可以由具备照相功能的设备临时拍照取得。图片的形式满足设备存储要求即可，图片的内容以便于选取突出目标为佳。
步骤210之后进入步骤S220，即在选择图片后按照步骤S220判断所选择的图片是否适合作为密码图片(密码锁)，若是，进入步骤S230；若否，返回步骤S210继续选择图片，直至找到满意的密码图片为止。
在此步骤S220中，作为判断图片是否合适的条件，以图片具有明显特征为佳，例如：如果以人脸为热区，图片中应有一个以上人脸才能作为密码图片；如果以景 物作为热区，图片中应能够识别到两种以上景物才能作为密码图片，比如山、树木、海滩等。
此后进入到步骤S230，其中进一步选取操作区域作为热区。所选择的密码图片中热区的提取方式有多种：可以在密码图片中选取目标区域圈定若干区域，来选定热区；也可以在密码图片中选取多个突出目标，选定这些突出目标后就可以来设定热区。其中，这些突出目标可以是人脸，通过识别并提取人脸作为突出目标来设定热区；也可以是景物，通过分割并提取景物作为突出目标来设定热区。
该步骤S230中，选取热区的方式可以是手动，也可以是自动(如人脸检测、场景分割等)。在手动模式下，可以通过手指在手机屏幕上涂抹选择热区(画出边界可以作为一种方式)。在自动模式下，热区选择一般可以采取两种方式：其一，用户选择一种选取热区的方法，比如人脸，那么算法(预设程序)就在图片中找出人脸作为热区；其二，用户不选择方法，算法用人脸检测、场景分割、突出物体检测等算法依次进行检测来选取热区。此处，关于如何检测、识别人脸、景物等突出物体的具体算法请参见习知技术文献，在此不再赘述。
随后执行步骤S240，在该步骤S240中由用户基于这些突出的区域设定加密手势。也就是说，在设定好热区之后需要进一步设定加密手势的规则，然后由用户基于这些突出的区域设定加密手势。
在该步骤S240中，在选定加密图片的提取热区后，设置加密手势的规则可以有多种类型：一种手势规则是序列型，通过设定热区点击序列来获得加密手势，以通过热区的点击顺序来获得解密手势。另一种手势规则是关系型，通过设定热区连接关系来获得加密手势，以通过捕捉热区的连接关系来获得解密手势。在关系型密码规则下，可采用滑行操作方式连接热区，连接的热区可以滑行操作的起始位置、终止位置的坐标来进行识别。
本实施例的触控屏手势解锁方案中，加密过程是整个密码锁的基础。为了更好 地理解本申请的技术方案，现举出若干应用实例进行详细描述。
实例1：具有多个人脸的图片加密过程
参见图3a和图3b，示出具有多个人脸的密码图片加密过程，具体包括以下4个步骤：
Step 1：用户可以在设备中选择一张已有图片作为密码锁的基础，对于带有拍照功能的设备则可以临时拍照获取一张图片，本例中用户选择了如图3a所示的图片。
Step2:判断选择的图片是否适合作为密码图片。在本例中可使用自动人脸检测的方法来选取操作热区，判断图片中有6个人脸，符合设为密码图片要求。从图3a到图3b，通过自动人脸检测技术检测出人脸的外框，框中的内容就是热区。关于此处的自动人脸识别可采用习知技术，例如以下论文：
[1]Tie Liu,Zejian Yuan,Jian Sun,Jingdong Wang,Nanning Zheng,Xiaoou Tang,Heung-Yeung Shum,"Learning to Detect a Salient Object,"IEEE Transactions on Pattern Analysis and Machine Intelligence,vol.33,no.2,pp.353-367,Feb.2011
Step3:在选型的图片中选取操作热区，本例中使用模式识别技术，对图片内容进行分析，选取出若干个突出区域，作为用户可操作的热区。需指出的是，此处可以选择的模式识别算法没有局限，常见的显著物体检测算法都可以使用。此实例中，以采用人脸检测技术为例来解释发明的流程。经过该步骤中的人脸检测算法处理后，生成6个热区，图3b所示。
Step4：基于热区，由用户可定义一种模式作为加密手势。定义该加密手势后，如用户解锁时的解锁手势与加密手势一致，就能解锁。此处密码锁的规则可以灵活设定，具体要求可如前文所述，以两种模式来举例说明加密手势：
(1)序列型：用户定义一个顺序，按照这个顺序依次点击人脸来解锁。例如用户在设置密码的时候按照2-4-6-5-3-1的顺序依次点击人脸；那么在解锁的时候， 只有按照这个顺序依次点击人脸，才能成功解锁。
(2)关系型：用户定义一个关系，例如用户在设置密码的时候，规定要分别连接1-2，3-4，5-6；那么解锁的时候，用户只有正确连接了1-2，3-4，5-6之后，才能成功解锁。
实例2：具有多个景物的图片加密过程
参见图4a和图4b，示出具有多个景物的密码图片加密过程，具体包括以下4个步骤：
Step1：用户选择一张图片，如图4a所示。
Step2：该图片具有多种景物，符合要求。
Step3：使用场景区域分割技术，将图片区域分割为5个部分，如图4b所示。关于场景分割的技术资料可参考习知技术，例如参考以下论文：
[2]Zhuowen Tu,Xiangrong Chen,Alan L.Yuille,Song-Chun Zhu,"Image Parsing:Unifying Segmentation,Detection,and Recognition,"International Journal of Computer Vision,Volume 63,Number 2,pp.113-140 July 2005
Step4：用户可以根据分割结果定义加密手势，例如，用户一次点击：树木->海滩->山，就定义了一个加密手势。用户解锁的时候，看到的是原图(图4a)，如果用户依次点击树木、海滩和山的区域，就能解锁。
上述实施例以自然图片为基础，在用户选择的特定图片上，利用模式识别和计算机图形学的技术，提取突出目标作为用户点击热区，然后由用户确定的特定规则来点击或者滑动进行解锁。这本质上是一片基于图片分析的手势密码锁，其中的密码图片及加密手势可以由用户灵活设定。
这种密码锁的方案解决了传统解锁模式较为单一的问题，主要表现在：(1)用户自主选择图片来进行处理，并获取热区(点)，图片的多样性保证了模式的多样性；(2)用户可以选择多种规则来定义密码，增加了模式的多样性。同时，该实 施例可以使用连续点击的方式解锁，因而操作起来拥有和九宫格手机密码一样的便利性。
以上对触控屏的手势解锁方法(以下简称方法)进行了详细描述。在此基础上，本申请还相应地构设了触控屏的手势解锁装置(以下简称装置)，以下进行详细的描述。
顺便指出的是，本实施例装置中如有描述不尽之处，请参见前文方法部分的描述内容；同样地，前述方法部分中如涉及到装置的结构，也可以引见以下的描述内容。
请参见图5，表示本申请实施例触控屏的手势解锁装置的组成框图。该触控屏的手势解锁装置500由密码创建模块510、界面展示模块520、手势检测模块530、手势识别模块540、锁定解锁模块550和解锁主控模块560等部分组成，以下具体描述各部分功能。

具体地，该密码创建模块510在创建密码图片时，其中的密码图片具有多个突出目标，这样可以通过选定突出目标(如人脸、景物)来设定热区。该密码创建模块510中，可以通过设定热区点击序列或热区连接关系作为加密手势：对于前者，解锁时通过热区的点击顺序来获得解密手势；对于后者，解锁时可以通过捕捉热区的连接关系，来获得解密手势。
该触控屏的手势解锁装置500还具有界面展示模块520，其在触控屏处于锁定状态下展现预设的密码图片。在展现该密码图片后，用户可对触控屏进行解锁操作。
可以理解的是，该触控屏的手势解锁装置500具有该手势检测模块530，它可以检测触控屏的触控事件，以获得与热区相关的解密手势。这些触控事件可以是点击、 滑行等操作，根据它们可以捕捉到解锁手势。
手势识别模块540，被配置为将解密手势与加密手势相比较，以判断解密手势与加密手势是否匹配；以及，在解密手势与加密手势相匹配时，输出手势识别成功结果。根据这一手势识别成功结果，触控屏将被转换到解锁状态。
锁定解锁模块550，被配置为根据手势识别成功结果输出解锁指令，以将触控屏切换到解锁状态。否则，在解密手势与加密手势不匹配时，根据输出手势识别失败结果，使触控屏维持在锁定状态。
此外，图5所示的触控屏的手势解锁装置500还设置有解锁主控模块560，它用于调度及控制密码创建模块510、界面展示模块520、手势检测模块530、手势识别模块540及锁定解锁模块550的运行。
其中，当解密手势的当前触控位置位于热区之内时，手势解锁被激活。手势解锁被激活后，在下列一种或多种情形下，手势解锁被释放：解密手势的当前触控位置位于热区之外；解密手势的操作次数超过预设次数阈值；或者，解密手势的操作时间超过预设时间阈值时。在手势解锁释放后，先前获得的解密手势被重置，此时需要重新操作。
该图5对触控屏的手势解锁装置500进行了阐述，它提供了基于图片分析的手势密码系统。这一密码系统通过在自主设定的密码图片上来进行手势解锁，可有效地克服锁定解锁模式的单一问题，具有使用方便、变化丰富、可定制和可靠性高等突出的优点。
以上对触控屏的手势解锁装置500进行了描述，依照它的原理可以相应地得到具有手势解锁的电子设备。这种电子设备具有触控屏，它具有锁定状态和解锁状态，当该触控屏处于锁定状态下展现预设的密码图片，密码图片具有可用于设定加密手势的多个热区检测触控屏的触控事件，以获得与热区相关的解密手势；并将解密手势与所述加密手势相比较，以判断解密手势与加密手势是否匹配；在解密手势与加 密手势相匹配时，输出手势识别成功结果；否则，触控屏将保持在锁定状态。
