图1是本发明实施例一提供的指纹解密方法的流程图；
图2是本发明实施例二提供的指纹解密装置的结构图；
图3是本发明实施例二提供的指纹解密装置中解密模块的结构图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅 仅用以解释本发明，并不用于限定本发明。
实施例一
本发明实施例一提出一种指纹解密方法。如图1所示，本发明实施例一的方法包括步骤：
S1、接收输入的N个指纹输入，N为大于等于2的整数。
本发明实施例一通过指纹组合对待解密对象进行解密，该指纹组合包括2个或2个以上的指纹，除此之外，还可以包括其它非指纹的加密信息，如数字、字母等。
S2、根据接收的N个指纹对待解密对象进行解密，所述待解密对象由预先设置的N个指纹加密。
在本发明实施例中，预先设置N个指纹加密对象，得到待解密对象并存储。本发明实施例可以应用于任何需要加密解密的场合，如移动终端解锁、账号登录、支付和切换移动终端的工作模式、操作系统，壁纸、主题等。待解密对象包括但不限于文档、文件夹和应用APP。
相应地，需解密时接收输入的N个指纹。接收的N个指纹可以各不相同或者部分相同或者全部相同，同样，预先设置的N个指纹可以各不相同或者部分相同或者全部相同。如在指纹传感器上输入两次右手小指指纹(N＝2)，也可以分别输入左手拇指指纹和右手食指指纹，甚至是分别输入两个人的指纹。当N个指纹各不相同时，待解密对象的安全级别最高。
进一步地，还可预先设置N个指纹的输入总时间和/或输入时间间隔。
设置接收的N个指纹的输入总时间小于等于第一预设阈值。当输入指纹组合的总时间大于第一预设阈值，判定为输入的指纹不属于同一次输入(如输入 超过10秒，认为10秒后输入的指纹不属于本次解密输入的指纹内容)，
设置接收的N个指纹的输入时间间隔小于等于第二预设阈值。当相邻两次指纹输入的时间间隔大于第二预设阈值时，判定输入的多个指纹不属于同一次输入，或判定解密时输入的指纹组合与加密时输入的指纹组合不同。
在本发明实施例中，比较解密时的指纹输入与加密时的指纹，可预先定义解密时的指纹输入与加密时的指纹的匹配标准。在接收的指纹个数与预先设置的指纹个数相同的基础上，进行指纹匹配，指纹匹配可采用现有技术的算法，在此不再赘述。当接收的N个指纹和预先设置的N个指纹分别一一匹配时，对待解密对象进行解密。
在本发明实施例中，N个指纹均匹配时(当包含其它加密信息时，其它加密信息同样需要进行比较)，判定解密时输入的指纹组合与加密时设置的指纹组合一致。若预先设置的N个指纹中有部分指纹相同或者全部指纹相同，也可以设置该指纹的相同次数，而不需要重复设置该指纹。
进一步地，可以约定指纹输入的顺序，解密时，依次逐一比较接收的N个指纹和预先设置的N个指纹，当接收的N个指纹和预先设置的N个指纹分别一一匹配并且顺序一致时，对待解密对象进行解密。如严格限定指纹输入的顺序，则对于N个指纹均匹配的指纹组合，但其输入顺序不同，仍判定为不一致。
本发明实施例一通过包括2个或2个以上指纹的指纹组合对待解密对象进行解密，提高了移动终端数据或应用的安全性。且由于指纹的特殊性，用户在输入指纹时不必担心被周围的人偷窥，对于用户来说十分方便。另外，可以对指纹组合的输入总时间、输入时间间隔和输入顺序加以限制，提高数据的安全性。
本发明实施例一可应用于所有推荐指纹传感器的移动终端，由于目前市场上的平板、智能手机等移动终端普通安装有指纹传感器，因此无需增加成本设置额外设备即可实现。
实施例二
本发明实施例二提出一种指纹解密装置，该装置可以是移动终端本身，也可以是移动终端内置或外接的一装置。如图2所示，包括：
接收模块10，接收输入的N个指纹，N为大于等于2的整数；
解密模块30，根据接收的N个指纹对待解密对象进行解密，待解密对象由预先设置的N个指纹加密。
进一步地，如图3所示，解密模块30包括：
比较单元31，将接收的N个指纹和预先设置的N个指纹进行比较；
解密单元32，当接收的N个指纹和预先设置的N个指纹分别一一匹配时，对待解密对象进行解密。
比较单元31还具体用于依次逐一比较接收的N个指纹和预先设置的N个指纹。
当接收的N个指纹和预先设置的N个指纹分别一一匹配并且顺序一致时，解密单元32对待解密对象进行解密。
在本发明实施例中，预先设置N个指纹加密对象，得到待解密对象并存储。本发明实施例可以应用于任何需要加密解密的场合，如移动终端解锁、账号登录、支付和切换移动终端的工作模式、操作系统，壁纸、主题等。待解密对象包括但不限于文档、文件夹和应用APP。
相应地，需解密时接收输入的N个指纹。接收的N个指纹可以各不相同或 者部分相同或者全部相同，同样，预先设置的N个指纹可以各不相同或者部分相同或者全部相同。如在指纹传感器上输入两次右手小指指纹(N＝2)，也可以分别输入左手拇指指纹和右手食指指纹，甚至是分别输入两个人的指纹。当N个指纹各不相同时，待解密对象的安全级别最高。
进一步地，还可预先设置N个指纹的输入总时间和/或输入时间间隔。
设置接收的N个指纹的输入总时间小于等于第一预设阈值。当输入指纹组合的总时间大于第一预设阈值，判定为输入的指纹不属于同一次输入(如输入超过10秒，认为10秒后输入的指纹不属于本次解密输入的指纹内容)，
设置接收的N个指纹的输入时间间隔小于等于第二预设阈值。当相邻两次指纹输入的时间间隔大于第二预设阈值时，判定输入的多个指纹不属于同一次输入，或判定解密时输入的指纹组合与加密时输入的指纹组合不同。
在本发明实施例中，解密模块30比较解密时的指纹输入与加密时的指纹，可预先定义解密时的指纹输入与加密时的指纹的匹配标准。在接收的指纹个数与预先设置的指纹个数相同的基础上，进行指纹匹配，指纹匹配可采用现有技术的算法，在此不再赘述。当接收的N个指纹和预先设置的N个指纹分别一一匹配时，对待解密对象进行解密。
在本发明实施例中，N个指纹均匹配时(当包含其它加密信息时，其它加密信息同样需要进行比较)，判定解密时输入的指纹组合与加密时设置的指纹组合一致。若预先设置的N个指纹中有部分指纹相同或者全部指纹相同，也可以设置该指纹的相同次数，而不需要重复设置该指纹。
进一步地，可以约定指纹输入的顺序，解密时，比较单元31依次逐一比较接收的N个指纹和预先设置的N个指纹，当接收的N个指纹和预先设置的N 个指纹分别一一匹配并且顺序一致时，解密单元32对待解密对象进行解密。如严格限定指纹输入的顺序，则对于N个指纹均匹配的指纹组合，但其输入顺序不同，仍判定为不一致。
本发明实施例二通过包括2个或2个以上指纹的指纹组合对待解密对象进行解密，极大地提高了移动终端数据或应用的安全性。且由于指纹的特殊性，用户在输入指纹时不必担心被周围的人偷窥，对于用户来说十分方便。另外，可以对指纹组合的输入总时间、输入时间间隔和输入顺序加以限制，提高数据的安全性。
本发明实施例二的装置可应用于所有推荐指纹传感器的移动终端，由于目前市场上的平板、智能手机等移动终端普通安装有指纹传感器，因此无需增加成本设置额外设备即可实现。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
