本申请要求天地融科技股份有限公司于2015年12月10号提交中国专利局、申请号为201510917162.6、发明名称为“利用生物特征进行信息获取、提取的方法、系统和设备”的中国专利申请的优先权。
技术领域
本发明涉及一种利用生物特征进行信息传递的技术领域，尤其涉及一种利用生物特征进行信息获取、提取的方法、系统和设备。
背景技术
随着互联网技术的发展，电子商务交易也广泛应用于人们的生活中，目前，用户对交易活动内容进行确认时，输入密码这种方式对用户而言存在容易被盗取的危险，因此需要一种方便的、无需用户在其它设备输入交易的方法。
由于电子交易过程是通过开放的媒体进行的，在进行电子商务活动中特别是网上发送有价消息如订货单、电子支票时，交易双方有可能对交易的内容(例如金额和/或数量等)进行抵赖，因此需要一种可以防止交易双方对交易内容进行抵赖的方法。
另外，在电子交易过程中也难免发生交易双方对自己所做行为(例如是否签收)的否认，例如在快递签收时，就需要保证签收人对已签收快递的行为不能抵赖，因此，需要一种可以防止交易双方对自己所做行为进行抵赖的方法。
随着眼睛虹膜的研究越来越深入，已知人的眼睛结构由巩膜、虹膜、瞳孔、视网膜等部分组成。虹膜是位于瞳孔和巩膜之间的圆环状部分，其包含很多相互交错的斑点、细丝、冠状、条纹、隐窝等的细节特征。而且虹膜在胎儿发育阶段形成后，在整个生命历程中将是保持不变的。这些特征决定了虹膜特征的唯一性，同时不同特征的虹膜受到光刺激会收缩，特定节奏的光刺激会造成虹膜有规律的收缩，因此，如何利用生物特征防止交易双方对交易内容或交易行为进行抵赖是目前需要解决的技术问题。

具体实施方式
下面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，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明的实施例，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，都属于本发明的保护范围。
下面将结合附图对本发明实施例作进一步地详细描述。
实施例1
图1为本实施例提供一种利用生物特征进行信息获取的方法的流程示意图，如图1所示，该方法包括以下步骤(S101-S103)：
S101：终端获取第一数据；
在本实施例中，终端可以为以下任意设备：智能手机、平板电脑、笔记本电脑、PC机、电子签名设备(例如工行U盾、农行K宝)或可穿戴设备等设备。
在本实施例中，第一数据是需要通过虹膜收缩活动进行表示的数据。第一数据可以是时间、地点、人物(例如姓名)、订单信息、交易信息和签名数据任意之一或其任意组合，也可以是对上述时间、地点、人物、订单信息、交易信息和签名数据任意之一或其组合进行计算生成的特征值，当然也可以是上述时间、地点、人物、订单号和签名数据任意之一或其任意组合与上述特征值组合生成的数据，只要是需要通过虹膜收缩活动进行表示的数据都可作为第一数据，本实施例不做限定。计算生成特征值的方法可以采取多种方式，例如，本发明待计算的数据为N位，可以选取数据中的前X位作为特征值，其中，1≤X≤N，或者，通过杂凑算法或MAC算法等计算出Y位数据作为特征值，其中，1≤Y≤N。通过选取特征值作为第一数据可以提高效率，可以在第一数据太多时减少光照对虹膜的刺激。
作为一种可选的实施方式，第一数据也可以是对不同事件的编号，例如，在取快件的事件中，第一数据可以为1，在购物的事件中，第一数据可以为2，在打车的事件中，第一数据可以为3。当然，第一数据也可以是对不同事件下的应用场景编号，编号可以采用事件加应用场景的方式，例如，取顺丰快递的应用场景下，第一数据可以为11，取圆通快递的应用场景下，第一数据可以为12，取中通快递的应用场景下，第一数据可以为13；在凯德茂购物的应用场景下，第一数据可以为21，在物美购物的应用场景下，第一数据可以为22，在沃尔玛购物的应用场景下，第一数据可以为23。在利用数字对不同事件和/或应用场景进行编号的情况下，通过第一数据即可以方便确认是对何种事件进行的确认、签收或其它操作。
在本实施例中，终端可通过自身生成第一数据，例如可通过终端输入生成第一数据；当然，终端也可通过扫描二维码或条形码的方式获取第一数据，通过扫描的方式获取第一数据可以减少输入的繁琐。优选的，终端可通过接收后台服务器发送数据的方式获取第一数据，通过接收后台服务器发送的第一数据可以避免对第一数据的恶意篡改。
S102：终端根据第一数据控制光源生成强度变化的光信号，并将强度变化的光信号投射在虹膜上；
在本实施例中，光源可以为红外光、可见光或白光，只要光源是能引起虹膜收缩或舒张的光源即在本发明的保护范围内。优选的，可以使用手机等终端的闪光灯作为光源，不需要对手机等终端增加额外的光源产生装置。
终端根据第一数据控制光源生成强度变化的光信号至少包括以下方式之一：
方式一：终端将第一数据按照预设的调制方式调制到光源上，生成强度变化的光信号；
具体的，第一数据可用包含“0”和“1”的二进制数据表示，作为调制信号。光源作为载波信号，调制信号(第一数据)通过强度调制的方式调制到载波信号上生成已调信号，载波的强度随着调制信号的变化而变化。例如，预设的调制方式是：“0”用无光表示，“1”用有光表示；第一数据为“1001011010”时，生成的已调信号的状态表示为“有光、无光、无光、有光、无光、有光、有光、无光、有光、无光”，已调信号是强度变化的光信号。另外，调制方式也可为其它调制方式，例如幅度调制，只要是能生成强度变化的光信号且该强度变化的光信号能引起虹膜收缩活动的调制方式都在本发明的保护范围。通过将第一数据调制到光源上可以生成强度变化的光信号，用以刺激虹膜，另外，通过强度调制生成强度变化的光信号实现起来比较容易。
方式二：终端对第一数据进行编码生成第一数据的编码信号，并将编码信号按照预设的调制方式调制到光源上，生成强度变化的光信号。
在本实施例中，终端对第一数据进行编码的编码方式可以为NRZI编码，具体的，NRZI编码规则为：用电平不变表示第一数据的逻辑“1”，用电平翻转表示第一数据的逻辑“0”。第一数据“1001011010”经过NRZI编码后生成编码信号“1011000110”，具体的可参照图2，需要说明的是，图2中Idle是预设的参考电平信号，通过对第一数据进行NRZI编码并根据编码信号控制光源生成强度变化的光信号，可以用虹膜的收缩状态是否变化表示第一数据。另外，终端对第一数据进行编码的编码方式也可以为三进制编码，第一数据为“1001011010”，对第一数据进行三进制编码后的编码信号为“211022”。编码信号是三进制数据，用包含“0”、“1”和“2”的数字串表示，作为调制信号，光源作为载波信号，编码信号通过强度调制的方式调制到载波信号上生成已调信号，载波的强度随着调制信号而变化。例如，预设的调制规则是：“0”用无光表示，“1”用弱光表示，“2”用强光表示，不同强度的光信号引起虹膜不同程度的收缩，可用多种不同程度的虹膜收缩状态对第一数据进行表示。当然，也可为其它的编码方式，本实施例不做限定。
作为本实施例的一种可选实施方式，终端根据第一数据控制光源生成强度变化的光信号之前，还包括：终端根据基准数据控制光源生成基准光信号。其中，基准数据可以是预先存 储在终端中的，也可以是终端与后台服务器协商后生成的，具体的本实施例不做限定，只要实现本实施例中基准数据的作用即在本发明的保护范围之内。终端根据基准数据控制光源生成基准光信号的实施方式与上述终端根据第一数据控制光源生成强度变化的光信号的实施方式相同，在此不再赘述。根据基准数据控制光源生成的基准光信号也是闪烁的光信号，生成基准光信号后，将基准光信号投射在虹膜上，虹膜受到基准光信号的刺激生成基准虹膜收缩信息，基准虹膜收缩信息包括虹膜收缩活动，具体的，基准光信号是闪烁的光信号，当有光时虹膜成收缩状态，当无光时虹膜成舒张状态，基准光信号不断闪烁，虹膜不断的收缩或舒张，生成基准虹膜收缩活动。根据基准数据控制光源生成的基准光信号可刺激虹膜生成基准虹膜收缩活动，基准虹膜收缩活动可以作为基线对虹膜收缩活动进行校准。
S103：终端获取第一虹膜信息，第一虹膜信息至少包括第一虹膜收缩信息，其中，第一虹膜收缩信息是虹膜根据强度变化的光信号生成的，第一虹膜收缩信息包括第一虹膜收缩活动。
在本实施例中，终端获取第一虹膜信息，第一虹膜信息至少包括第一虹膜收缩信息。其中，获取第一虹膜收缩信息的具体实施方式为：将S102中的强度变化的光信号投射在虹膜上后，虹膜受到强度变化的光信号的刺激，当有光时虹膜成收缩状态，当无光时虹膜成舒张状态，强度变化的光信号不断闪烁，虹膜不断的收缩或舒张，生成第一虹膜收缩信息，第一虹膜收缩信息包括第一虹膜收缩活动。在本实施例中，将需要确认、签收的数据或其它数据用第一虹膜收缩信息表示提供了一种全新的用生物特征变化进行数据表示的方法。
作为本实施例的一种可选实施方式，终端获取图像采集组件对第一虹膜收缩活动进行图像采集所生成的图像信息并保存。其中，图像采集组件可以是在终端内部，也可以是与终端连接的外部的图像采集组件，本实施例对图像采集组件不做限定，只要能实现图像采集组件的功能即在本发明的保护范围内。优选的，图像采集组件设置在终端内部，例如手机终端的摄像头即可作为图像采集组件，摄像头作为图像采集组件不需要增加额外的组件，可以减少成本，另外图像采集组件设置在终端内部具有方便快捷的优点。另外，终端获取的第一虹膜收缩活动的图像信息可以是视频也可以是图片，本实施例不做限定。虹膜作为人体的唯一的、不变的生物特征，利用图像采集组件获取虹膜收缩活动并保存，可以将采集到的虹膜收缩活动作为证据存储，一方面可以用虹膜收缩对数据进行表示并存储，另一方面以防止用户对已做的签收、确认或其它操作行为进行抵赖。
作为本实施例的一种可选实施方式，终端还可以获取第二虹膜信息，第二虹膜信息至少包括第二虹膜收缩信息。其中，第二虹膜信息与第一虹膜信息可以相同，也可以不同，当第二虹膜信息不同时，第二虹膜信息还可通过无线传输(蓝牙、wifi、2G、3G、4G、NFC或光通信)或有线传输(USB传输或音频接口传输)的方式从其它终端获取。终端获取第二 虹膜信息后，根据预设规则从第二虹膜收缩信息中提取第二数据，具体实施方式可参见实施例2中终端根据预设规则从第一虹膜收缩信息中提取第一数据的实施方式。另外，第二虹膜信息中还可包括第二虹膜特征信息，终端获取第二虹膜特征信息后，验证第二虹膜特征信息的合法性。本实施例中的终端不仅可以获取虹膜信息，而且还可以对虹膜信息进行处理以提取数据和/或验证虹膜特征信息的合法性。
通过本实施例提供的利用生物特征进行信息获取的方法，将可以利用生物特征对数据进行表示，将数据嵌入生物特征中，用户只需要接受强度变化的光信号对虹膜的照射即可实现对数据信息的确认签收等操作；另外，嵌入生物特征中的数据可作为证据保存，即将确认、签收等操作的执行主体(用户)与确认、签收的内容进行了绑定存储，防止用户对已确认或签收的内容进行抵赖。
实施例2
图3为本实施例提供一种利用生物特征进行信息提取的方法的流程示意图，如图3所示，该方法包括以下步骤(S201-S202)：
S201：后台服务器接收终端发送的第一虹膜信息；
在本实施例中，终端通过实施例1中的实施方式获取第一虹膜信息，第一虹膜信息至少包括第一虹膜收缩信息，终端获取第一虹膜信息后，通过无线传输式或有线传输的方式发送至后台服务器，后台服务器接收终端发送的第一虹膜信息。
S202：后台服务器根据预设规则从第一虹膜收缩信息中提取第一数据。
在具体应用中，后台服务器接收到第一虹膜收缩信息后，后台服务器通过图像识别等算法识别出虹膜收缩的状态，具体的图像识别算法本实施例不做限定，只要能识别出虹膜收缩的状态即在本发明的保护范围内。当后台服务器识别出虹膜收缩的状态为“收缩、舒张、舒张、收缩、舒张、收缩、收缩、舒张、收缩、舒张”时，且后台服务器预设的规则是“舒张”代表逻辑“0”，“收缩”代表逻辑“1”，则从虹膜收缩的状态“收缩、舒张、舒张、收缩、舒张、收缩、收缩、舒张、收缩、舒张”可以提取出第一数据为“1001011010”。当后台服务器识别出虹膜收缩的状态为“收缩、舒张、收缩、收缩、舒张、舒张、舒张、收缩、收缩、舒张”时，且后台服务器预设的规则是“虹膜保持收缩或舒张”代表逻辑“1”，“虹膜由舒张转为收缩或由收缩转为舒张”代表逻辑“0”，预置的初始虹膜收缩状态为“收缩”，识别出的第一个虹膜收缩状态是“收缩”，相对于预置的初始虹膜收缩状态“收缩”是“虹膜保持收缩”，所以代表逻辑“1”，识别出的第二个虹膜收缩状态是“舒张”，相对于第一个虹膜收缩状态“收缩”是“虹膜由收缩转为舒张”，所以代表逻辑“0”，以此类推，则从虹膜收缩的状态“收缩、舒张、收缩、收缩、舒张、舒张、舒张、收缩、收缩、舒张”可以提取出第一数据为“1001011010”。另外，当后 台服务器识别出虹膜收缩的状态为“大幅收缩、半度收缩、半度收缩、舒张、大幅收缩、大幅收缩”时，且后台服务器预设的规则是“大幅收缩”代表逻辑“2”，“半度收缩”代表逻辑“1”，“舒张”代表逻辑“0”，则后台服务器可得到三进制的编码的第一数据为“211022”，可选的，后台服务器将三进制的编码的第一数据转化为二进制即可提取出第一数据“1001011010”。通过从虹膜收缩信息中提取出第一数据，提供了一种全新的从生物特征的变化中获取数据的方法，即可以从嵌入数据的生物特征中提取出用户确认、签收等操作所确认或签收的内容，防止用户对已确认或签收的内容进行抵赖。
作为本实施例的一种可选实施方式，第一虹膜信息还包括虹膜特征信息，虹膜特征信息是在胎儿发育阶段就形成的，在整个生命历程中是保持不变的，每个人的虹膜的特征信息都是不同的，因此虹膜的特征信息具有唯一性。后台服务器接收到终端发送的虹膜特征信息后，验证虹膜特征信息的合法性，具体实施方式为：后台服务器将接收到的虹膜特征信息与预先存储虹膜特征信息进行比对是否相同，如果相同，则说明虹膜特征信息合法，如果不同则说明虹膜特征信息不合法。通过验证虹膜特征信息是否合法可以防止非法分子进行确认、签收或者其它操作，另外，后台服务器接收到虹膜特征信息还可作为证据存储，防止对已经做出的确认、签收或其它操作行为进行抵赖。
作为本实施例的一种可选实施方式，后台服务器验证虹膜特征信息的合法性之后，将验证结果发送至终端。例如，后台服务器验证虹膜特征信息不合法后，后台服务器通过有线或无线的方式将验证结果发送至终端，终端接收到验证不合法的结果后，可通过报警或显示等方式提醒终端用户。通过将验证结果返回终端可以方便终端用户即时确认虹膜用户是否合法。
作为本实施例的一种可选实施方式，在后台服务器根据预设规则从第一虹膜收缩信息中提取第一数据之前，后台服务器接收终端发送的基准虹膜收缩信息，后台服务器根据基准数据和基准虹膜收缩信息计算生成基准数据与基准虹膜收缩活动的对应关系。其中，基准数据可以是预先存储在后台服务器中的，也可以是后台服务器与终端协商后生成的，为保证正确的提取数据，后台服务器和终端使用的基准数据是相同的。下面对生成基准数据与基准虹膜收缩活动的对应关系的实施方式进行举例说明，终端与后台服务器协商生成基准数据的三进制表示是“012012”，终端在根据第一数据控制光源生成强度变化的光信号之前，终端根据基准数据“012012”控制光源生成基准光信号，该基准光信号也是强度变化的信号，基准光信号刺激虹膜产生基准虹膜收缩信息，终端获取该基准虹膜收缩信息并发送至后台服务器，后台服务器接收到终端发送的基准虹膜收缩信息后，利用图像识别算法识别接收到的基准虹膜活动中的瞳孔直径是“4mm、3mm、2mm、4mm、3mm、2mm”，后台服务器中的基准数据与终端中的基准数据相同为“012012”，则根据上述识别出的瞳孔直径与基准数据建立基准数据 与虹膜收缩活动的对应关系为：瞳孔直径为4mm时，基准数据为逻辑“0”；瞳孔直径为3mm时，基准数据为逻辑“1”；瞳孔直径为2mm时，基准数据为逻辑“2”。通过建立基准数据与虹膜收缩活动的对应关系，可以方便后台服务器判断虹膜收缩或舒张的不同程度所代表的逻辑数据。另外，基准数据与虹膜收缩活动的对应关系还包括：基准数据与虹膜收缩活动的活动范围的对应关系。具体的，虹膜收缩活动的活动范围可以为用户的瞳孔直径的范围，例如，用户的瞳孔直径在[4.2mm，3.8mm)的范围内时，基准数据为逻辑“0”，瞳孔直径在[3.4mm,3.2mm)的范围内时，基准数据为逻辑“1”，瞳孔直径在[2.5mm,2.3mm)的范围内时，基准数据为逻辑“2”。通过建立基准数据与虹膜收缩活动的活动范围的对应关系，可以避免精确识别下有些虹膜收缩程度无法被识别的情况。
作为一种可选实施方式，不同的用户可以设置不同的基准数据与虹膜收缩活动的对应关系。具体的，虹膜收缩活动可以用户的瞳孔大小来表征，例如，设置甲的基准数据与虹膜收缩活动的对应关系为：瞳孔直径为4mm时，基准数据为逻辑“0”，瞳孔直径为3mm时，基准数据为逻辑“1”，瞳孔直径为2mm时，基准数据为逻辑“2”，设置甲的基准数据与虹膜收缩活动的对应关系为：瞳孔直径为3.6mm时，基准数据为逻辑“0”，瞳孔直径为2.8mm时，基准数据为逻辑“1”，瞳孔直径为2.2mm时，基准数据为逻辑“2”。当然，基准数据与虹膜收缩活动的对应关系还包括：基准数据与虹膜收缩活动的活动范围的对应关系，不同的用户可以设置不同的基准数据与虹膜收缩活动的活动范围的对应关系，具体的，虹膜收缩活动的活动范围可以为用户的瞳孔直径的范围，例如，设置用户甲的基准数据与虹膜收缩活动的对应关系为：瞳孔直径在[4.2mm，3.8mm)的范围内时，基准数据为逻辑“0”，瞳孔直径在[3.4mm,3.2mm)的范围内时，基准数据为逻辑“1”，瞳孔直径在[2.5mm,2.3mm)的范围内时，基准数据为逻辑“2”，设置用户乙的基准数据与虹膜收缩活动的对应关系为：瞳孔直径在[3.7mm，3.5mm)的范围内时，基准数据为逻辑“0”，瞳孔直径在在[2.9mm,2.7mm)的范围内时，基准数据为逻辑“1”，虹膜大小在收缩[2.3mm,2.1mm)的范围内时，基准数据为逻辑“2”。优选的，可以将虹膜特征信息和上述基准数据与虹膜收缩活动的对应关系进行对应存储，后台服务器可根据虹膜特征信息查找基准数据与虹膜收缩活动的对应关系，通过将虹膜特征信息与对应关系关联存储，不同的用户可以设置不同的基准数据与虹膜收缩活动的对应关系。当然，也可通过其它方式实现不同的用户设置不同的基准数据与虹膜收缩活动的对应关系，本实施例不做限定。不同的用户设置不同的基准数据与虹膜收缩活动的对应关系，可以防止不同人使用同一基准造成数据提取错误。
通过本实施例提供的利用生物特征进行信息提取的方法，可以从嵌入数据的生物特征中提取恢复出数据，即可以从嵌入数据的生物特征中提取出用户确认、签收等操作所确认或签收的内容，防止用户对已确认或签收的内容进行抵赖。
实施例3

其中，第一获取组件401，用于获取第一数据；光源生成组件402，用于生成光源；控制组件403，用于根据第一数据控制光源生成强度变化的光信号；输出组件404，用于将强度变化的光信号投射在虹膜上；第一获取组件401，还用于获取第一虹膜信息，第一虹膜信息至少包括第一虹膜收缩信息，其中，第一虹膜收缩信息是虹膜根据强度变化的光信号生成的，第一虹膜收缩信息包括第一虹膜收缩活动。
在本实施例中，第一获取组件401获取的第一数据是需要通过虹膜收缩活动进行表示的数据。第一数据可以是时间、地点、人物(例如姓名)、订单信息、交易信息和签名数据任意之一或其任意组合，也可以是对上述时间、地点、人物、订单信息、交易信息和签名数据任意之一或其组合进行计算生成的特征值，当然也可以是上述时间、地点、人物、订单号和签名数据任意之一或其任意组合与上述特征值组合生成的数据，只要是需要通过虹膜收缩活动进行表示的数据都可作为第一数据，本实施例不做限定。计算生成特征值的方法可以采取多种方式，例如本发明待计算的数据为N位，可以选取数据中的前X位作为特征值，其中，1≤X≤N，或者，通过杂凑算法或MAC算法等计算出Y位数据作为特征值，其中，1≤Y≤N。通过选取特征值作为第一数据可以提高效率，可以在第一数据太多时减少光照对虹膜的刺激。
作为一种可选的实施方式，第一数据也可以是对不同事件的编号，例如，在取快件的事件中，第一数据可以为1，在购物的事件中，第一数据可以为2，在打车的事件中，第一数据可以为3。当然，第一数据也可以是对不同事件下的应用场景编号，编号可以采用事件加应用场景的方式，例如，取顺丰快递的应用场景下，第一数据可以为11，取圆通快递的应用场景下，第一数据可以为12，取中通快递的应用场景下，第一数据可以为13；在凯德茂购物的应用场景下，第一数据可以为21，在物美购物的应用场景下，第一数据可以为22，在沃尔玛购物的应用场景下，第一数据可以为23。在利用数字对不同事件和/或应用场景进行编号的情况下，通过第一数据即可以方便确认是对何种事件进行的确认、签收或其它操作。
在本实施例中，光源生成组件402生成的光源可以为红外光、可见光或白光。光源生成组件402可以为红外灯或闪光灯等，本实施例不做具体限定，光源生成组件402只要实现能够生成光源且该光源能够引起虹膜收缩或舒张的功能即在本发明的保护范围内。优选的，手机等终端中的闪光灯可以作为光源生成组件402，利用手机等终端已有的闪光灯作为光源生成组件，不需要对手机等终端增加额外的光源生成组件，减少成本。
在本实施例中，控制组件403可通过将第一数据调制到光源上的方式生成强度变化的光信号，当然，控制组件403也可先将第一数据编码后再调制到光源上生成强度变化的光信号，控制组件403生成强度变化的光信号后，由输出组件404将强度变化的光信号投射在虹膜上。虹膜受到强度变化的光信号的刺激，生成第一虹膜收缩信息，第一获取组件401还用于获取虹膜信息，其中第一虹膜信息至少包括第一虹膜收缩信息。通过本实施例提供的终端，可以刺激虹膜产生变化并获取利用虹膜收缩信息表示的数据信息。
作为本实施例的一种可选实施方式，第一获取组件401，可通过获取图像采集组件405对第一虹膜收缩活动进行图像采集所生成的图像信息的方式获取第一虹膜信息。如图5所示，图像采集组件405可以设置在终端内部，图像采集组件405对第一虹膜收缩活动进行图像采集生成图像信息后，存储组件406存储图像采集组件405采集到的图像信息，第一获取组件401从图像采集组件405中获取第一虹膜收缩活动的图像信息。当然，图像采集组件也可以设置在终端外部，图像采集组件可通过无线或有线方式与终端40连接，图像采集组件通过无线传输或有线传输的方式将采集的第一虹膜收缩活动的图像信息发送至第一获取组件401，第一获取组件401获取第一虹膜收缩活动的图像信息。通过第一获取组件401获取第一虹膜收缩活动的图像信息并保存，一方面可以用虹膜收缩对数据进行表示并存储，另一方面以防止用户对已做的签收、确认或其它操作行为进行抵赖。
作为本实施例的一种可选实施方式，如图5所示，终端40还包括第二获取组件407和提取组件408，其中，第二获取组件407用于获取第二虹膜信息，第二虹膜信息至少包括第二虹膜收缩信息，提取组件408用于根据预设规则从第二虹膜收缩信息中提取第二数据。具体实施时，第二虹膜收缩信息可以与第一虹膜收缩信息相同，也可以不同，第二获取组件407可以通过上述第一获取组件401获取第一虹膜信息的方式获取第二虹膜信息，也可以是其它终端获取第二虹膜信息后发送至第二获取组件407，第二获取组件407获取其它终端发送的第二虹膜信息的方式获取第二虹膜信息。第二获取组件407获取第二虹膜收缩信息后，提取组件408根据预设规则从第二虹膜收缩信息中提取第二数据的方式可参见实施例4中提取组件502根据预设规则从第一虹膜收缩信息中提取第一数据的实施方式。另外，第一虹膜信息中还可包括第二虹膜特征信息，第二获取组件407获取第二虹膜特征信息后，验证第二虹膜特征信息的合法性。通过在终端中设置提取组件408可以利用终端对虹膜信息进行处理以提取数据和/或验证虹膜特征信息的合法性。
作为本实施例的一种可选实施方式，如图5所示，第一数据可通过第一数据生成组件409生成，第一获取组件401从第一数据生成组件409中获取第一数据。优选的，也可通过接收组件410接收后台服务器发送的第一数据，第一获取组件再从接收组件410中获取第一数据的方式获取第一数据。通过接收组件410接收后台服务器发送的第一数据可以避免对第 一数据的恶意篡改
作为本实施例的一种可选实施方式，控制组件403还用于根据基准数据控制光源生成基准光信号。其中，基准数据可以是第一获取组件401与后台服务器协商生成的数据或者是存储在存储组件406中的数据，但是上述基准数据要与后台服务器中的基准数据相同。控制组件403根据基准数据控制光源生成基准光信号的实施方式与控制组件403根据第一数据控制光源生成强度变化的光信号的实施方式相同，在此不再赘述，可以理解的是基准光信号也是强度变化的信号。控制组件403控制光源生成基准光信号后，输出组件404将基准光信号投射在虹膜上。第一获取组件401还用于获取基准虹膜信息，基准虹膜信息至少包括基准虹膜收缩信息。终端40获取的基准虹膜收缩信息可在后续识别第一虹膜收缩信息的过程中作为基准信息对虹膜收缩活动进行校准。
通过本实施例提供的终端，可以获取利用生物特征表示的数据，防止用户对已确认或签收的内容进行抵赖。
实施例4
图6为本实施例提供一种后台服务器的结构示意图，如图6所示，该后台服务器50包括接收组件501和提取组件502。其中，接收组件501用于接收终端40发送的第一虹膜信息，第一虹膜信息至少包括第一虹膜收缩信息；提取组件502用于根据预设规则从第一虹膜收缩信息中提取第一数据。
在本实施例中，终端40可通过实施例1中的方式获取第一虹膜信息，终端40获取第一虹膜信息后发送至后台服务器50，后台服务器50中的接收组件501接收终端40发送的第一虹膜信息，第一虹膜信息至少包括第一虹膜收缩信息。提取组件502根据预设规则从第一虹膜收缩信息中提取第一数据的实施方式为：提取组件502首先从虹膜收缩信息中利用图像识别等算法识别出虹膜收缩的状态，例如是“收缩”还是“舒张”，具体的图像识别算法本实施例不做限定，只要是能识别出虹膜收缩的状态即可。当提取组件502识别出的虹膜收缩的状态为“收缩、舒张、舒张、收缩、舒张、收缩、收缩、舒张、收缩、舒张”，且预设规则是“舒张”代表逻辑“0”，“收缩”代表逻辑“1”时，则从可提取出第一数据为“1001011010”。当提取组件502识别出虹膜收缩的状态为“收缩、舒张、收缩、收缩、舒张、舒张、舒张、收缩、收缩、舒张”，且预设的规则是“虹膜保持收缩或舒张”代表逻辑“1”，“虹膜由舒张转为收缩或由收缩转为舒张”代表逻辑“0”，且预置的初始虹膜收缩状态为“收缩”时，提取组件502提取出的第一个虹膜收缩状态是“收缩”，相对于预置的初始虹膜收缩状态“收缩”是“虹膜保持收缩”，所以代表逻辑“1”，提取组件502提取出的第二个虹膜收缩状态是“舒张”，相对于第一个虹膜收缩状态“收缩”是“虹膜由收缩转为舒张”，所以代表逻辑“0”，以此类推，可以提取出第一 数据为“1001011010”。当提取组件502识别出的虹膜收缩的状态为“大幅收缩、半度收缩、半度收缩、舒张、大幅收缩、大幅收缩”，且预设的规则是“大幅收缩”代表逻辑“2”，“半度收缩”代表逻辑“1”，“舒张”代表逻辑“0”，则提取出第一数据的三进制表示是“211022”，可选的，提取组件502再将三进制数据转为二进制数据，提取出第一数据为“1001011010”。通过本实施例提供的后台服务器60可以从虹膜收缩信息中提取出第一数据。
作为本实施例的一种可选实施方式，如图7所示，后台服务器50还包括验证组件503，接收组件501接收终端40发送的第一虹膜信息，除了包括第一虹膜收缩信息外，还包括第一虹膜特征信息，验证组件503用于在接收组件501接收到终端40发送的虹膜特征信息后，验证第一虹膜特征信息的合法性。验证组件503验证第一虹膜特征信息的合法性的具体实施方式为：验证组件503将接收组件501接收到的虹膜特征信息与预先存储虹膜特征信息进行比对是否相同，如果相同，则说明虹膜特征信息合法，如果不同则说明虹膜特征信息不合法。通过验证虹膜特征信息是否合法可以防止非法分子进行确认、签收或者其它操作，另外，后台服务器接收到虹膜特征信息还可作为证据存储，防止对已经做出的确认、签收或其它操作进行抵赖。
作为本实施例的一种可选实施方式，验证组件503验证虹膜特征信息的合法性后，将验证结果发送至终端40。终端40接收到虹膜特征信息不合法的结果后，可通过报警或显示等方式提醒终端40的用户。通过将验证结果返回终端可以方便终端用户即时确认虹膜用户是否合法。
作为本实施例的一种可选实施方式，如图7所示，后台服务器还包括计算组件504。其中，计算组件504用于根据基准数据和基准虹膜收缩信息计算生成基准数据与基准虹膜收缩活动的对应关系。其中，基准数据与终端40中的基准数据相同，基准数据的获取方式也与实施例4中终端获取基准数据的方式相同，在此不再赘述。接收组件501接收第一虹膜收缩信息之前，还用于接收基准虹膜收缩信息，接收组件501接收到基准虹膜收缩信息后，计算组件504计算生成基准数据与基准虹膜收缩活动的对应关系，例如基准数据的三进制表示为“012012”时，建立的基准数据与虹膜收缩活动的对应关系为：瞳孔直径为4mm时，基准数据为逻辑“0”；瞳孔直径为3mm时，基准数据为逻辑“1”；瞳孔直径为2mm时，基准数据为逻辑“2”。提取组件502，用于根据基准数据与基准虹膜收缩活动的对应关系从第一虹膜收缩信息中提取第一数据，例如接收组件501接收到第一虹膜收缩信息后，提取组件502通过图像识别等算法识别出第一虹膜收缩活动中的瞳孔直径是“2mm、3mm、3mm、4mm、2mm、2mm”，根据上述关系提取出三进制编码数据“211022”，将三进制编码数据转化为二进制数据可提取出第一数据为“1001011010”。优选的，计算组件504计算生成的基准数据与虹膜收缩活动的对应关系还包括：基准数据与虹膜收缩活动的活动范围的对应关系，例如建立的基 准数据与虹膜收缩活动的对应关系为：瞳孔直径在[4.2mm，3.8mm)的范围内时，基准数据为逻辑“0”，瞳孔直径在[3.4mm,3.2mm)的范围内时，基准数据为逻辑“1”，瞳孔直径在[2.5mm,2.3mm)的范围内时，基准数据为逻辑“2”。提取组件502通过图像识别等算法识别出第一虹膜收缩状态：瞳孔直径是“2.4mm、3.2mm、3.3mm、4.1mm、2.3mm、2.3mm”，，根据上述对应关系提取出三进制编码数据为“211022”，将三进制编码数据转化为二进制数据可提取出第一数据为“1001011010”。通过建立基准数据与虹膜收缩活动的活动范围的对应关系，可以避免精确识别下有些虹膜收缩程度无法被识别的情况。
作为本实施例的一种可选实施方式，后台服务器50中还包括存储组件，用于存储不同用户的基准数据与虹膜收缩活动的对应关系。具体的，虹膜收缩活动可以用户的瞳孔大小来表征，例如，设置甲的基准数据与虹膜收缩活动的对应关系为：瞳孔直径为4mm时，基准数据为逻辑“0”，瞳孔直径为3mm时，基准数据为逻辑“1”，瞳孔直径为2mm时，基准数据为逻辑“2”，设置甲的基准数据与虹膜收缩活动的对应关系为：瞳孔直径为3.6mm时，基准数据为逻辑“0”，瞳孔直径为2.8mm时，基准数据为逻辑“1”，瞳孔直径为2.2mm时，基准数据为逻辑“2”。当然，基准数据与虹膜收缩活动的对应关系还包括：基准数据与虹膜收缩活动的活动范围的对应关系，不同的用户可以设置不同的基准数据与虹膜收缩活动的活动范围的对应关系，具体的，虹膜收缩活动的活动范围可以为用户的瞳孔直径的范围，例如，设置用户甲的基准数据与虹膜收缩活动的对应关系为：瞳孔直径在[4.2mm，3.8mm)的范围内时，基准数据为逻辑“0”，瞳孔直径在[3.4mm,3.2mm)的范围内时，基准数据为逻辑“1”，瞳孔直径在[2.5mm,2.3mm)的范围内时，基准数据为逻辑“2”，设置用户乙的基准数据与虹膜收缩活动的对应关系为：瞳孔直径在[3.7mm，3.5mm)的范围内时，基准数据为逻辑“0”，瞳孔直径在在[2.9mm,2.7mm)的范围内时，基准数据为逻辑“1”，虹膜大小在收缩[2.3mm,2.1mm)的范围内时，基准数据为逻辑“2”。优选的，在存储组件中可以将虹膜特征信息和上述基准数据与虹膜收缩活动的对应关系进行对应存储，这样，接收组件501接收到虹膜特征信息后，可以根据虹膜的特征信息在存储组件中查找虹膜特征信息对应的基准数据与虹膜收缩活动的对应关系，通过将虹膜特征信息与对应关系关联存储，不同的用户可以设置不同的基准数据与虹膜收缩活动的对应关系。当然，也可通过其它方式实现不同的用户设置不同的基准数据与虹膜收缩活动的对应关系，本实施例不做限定。不同的用户设置不同的基准数据与虹膜收缩活动的对应关系，可以防止不同人使用同一基准造成数据提取错误。
通过本实施例提供的后台服务器，可以从嵌入数据的生物特征中提取恢复出数据，防止用户对已确认或签收的内容进行抵赖。
