Abstract
本发明提出了一种鉴权方法、鉴权装置和终端，其中，所述鉴权方法包括：采集所述终端的用户的多个虹膜图像；提取所述多个虹膜图像中的当前虹膜特征点，并根据所述当前虹膜特征点在所述多个虹膜图像中的位置确定所述当前虹膜特征点的当前运动轨迹；根据所述当前运动轨迹与所述当前虹膜特征点对所述用户进行鉴权。通过本发明的技术方案，可以避免由于用户的虹膜特征点发生改变而导致虹膜鉴权的效率降低，从而保证了虹膜鉴权的可靠性，同时还有效地提高虹膜鉴权的安全性。
Description
本申请要求于2015年9月30日提交中国专利局、申请号为201510639237.9、发明名称为“鉴权方法、鉴权装置和终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及终端技术领域，具体而言，涉及一种鉴权方法、一种鉴权装置和一种终端。
目前，在相关技术中的虹膜鉴权的方案中，通过将采集的当前虹膜图像与数据库中预存的鉴权虹膜图像进行匹配，若匹配成功则鉴权成功，否则鉴权失败。具体地，通过提取当前虹膜图像中的虹膜特征点，例如，提取当前虹膜图像中的裂缝和抗洞，将当前虹膜图像中的虹膜特征点与鉴权虹膜图像中的虹膜特征点进行匹配。
但是，用户的虹膜图像中的虹膜特征点会受到外界因素的影响而发生变化。例如，用户的虹膜特征点会随着用户的年龄的增加而发生变化，用户的虹膜特征点也会随着用户的身体健康的变化而发生变化，还有用户的虹膜特征点也会随着用户的心理状况(如受到惊吓、心理压力大、情绪失控等)而发生变化。这样当虹膜特征点发生变化时，就导致虹膜识别的效率降低，也就导致了虹膜鉴权的效率较低。另外，非法用户会使用具有鉴权虹膜图像的虹膜套进行鉴权，这样非法用户很容易通过虹膜鉴权，也就降低了虹膜鉴权的安全性。
因此，如何避免由于用户的虹膜特征点发生改变而导致虹膜鉴权的效率降低，从而保证了虹膜鉴权的可靠性，同时提高虹膜鉴权的安全性成为亟待解决的问题。
发明内容
本发明正是基于上述问题，提出了一种新的技术方案，可以避免由于
用户的虹膜特征点发生改变而导致虹膜鉴权的效率降低，从而保证了虹膜鉴权的可靠性，同时还有效地提高虹膜鉴权的安全性。
有鉴于此，本发明的第一方面提出了一种鉴权方法，用于终端，包括：采集所述终端的用户的多个虹膜图像；提取所述多个虹膜图像中的当前虹膜特征点，并根据所述当前虹膜特征点在所述多个虹膜图像中的位置确定所述当前虹膜特征点的当前运动轨迹；根据所述当前运动轨迹与所述当前虹膜特征点对所述用户进行鉴权。
在该技术方案中，通过获取用户的多个虹膜图像中的当前虹膜特征点在多个虹膜图像中的位置来确定用户的当前运动轨迹，其中，当前虹膜特征点可以是虹膜中的裂缝、抗洞等，然后根据当前运动轨迹与当前虹膜特征点对用户进行鉴权，即由相关技术中的静态虹膜图像的鉴权上升到动态的虹膜图像的鉴权，避免了非法用户利用虹膜套进行鉴权来获取访问终端的权限，进一步地保证了虹膜鉴权的安全性，而且也避免了由于用户的虹膜特征点发生改变而导致虹膜鉴权的效率降低，从而保证了虹膜鉴权的可靠性。
另外，由于是对多个虹膜图像中的当前虹膜特征点的动态采样以得到当前虹膜特征点，当前虹膜特征点的数量相对于相关技术中的对虹膜图像静态鉴权时采样的虹膜特征点的数量少，从而可以降低采样的采样时间和等错率。而且当前虹膜特征点的数量的降低使得对鉴权的处理算法的要求降低，鉴权处理的负担也会降低，则减少了鉴权时所占用的资源，从而提高了鉴权效率。
在上述技术方案中，优选地，所述根据所述当前运动轨迹与所述当前虹膜特征点对所述用户进行鉴权的步骤，具体包括：判断所述当前运动轨迹与鉴权运动轨迹是否匹配；在判断结果为是时，将所述当前虹膜特征点与鉴权虹膜特征点进行对比，若所述当前虹膜特征点与所述鉴权虹膜特征点对比一致，则鉴权成功，否则，鉴权失败并提示所述用户；在判断结果为否时，鉴权失败并提示所述用户。
在该技术方案中，若判定当前运动轨迹与鉴权运动轨迹匹配，且当前虹膜特征点与鉴权虹膜特征点对比一致时，说明终端的用户为该终端的合
法用户，则鉴权成功，可以向该用户开放访问终端的权限；否则说明终端的用户为该终端的非法用户，禁止向该用户开放访问终端的权限，避免了非法用户利用虹膜套进行鉴权来获取访问终端的权限，进一步地保证了虹膜鉴权的安全性。其中，鉴权虹膜特征点可以从预先采集的鉴权虹膜图像中获取。
当然，也可以先将当前虹膜特征点与鉴权虹膜图像中的鉴权虹膜特征点进行对比，若对比一致，再判断当前运动轨迹与鉴权运动轨迹是否匹配。
在上述技术方案中，优选地，所述判断所述当前运动轨迹与鉴权运动轨迹是否匹配的步骤，具体包括：将所述当前运动轨迹与所述鉴权运动轨迹进行匹配；若所述当前运动轨迹与所述鉴权运动轨迹的匹配度大于预设匹配度时，判定所述当前运动轨迹与所述鉴权运动轨迹匹配，否则，判定所述当前运动轨迹与所述鉴权运动轨迹不匹配。
在该技术方案中，由于当前运动轨迹与鉴权运动轨迹很难达到一致，则在当前运动轨迹与鉴权运动轨迹匹配时，根据当前运动轨迹与鉴权运动轨迹的匹配度来判断当前运动轨迹与所述鉴权运动轨迹是否匹配，从而提高了判断虹膜鉴权的可靠性。
在上述技术方案中，优选地，在所述采集所述终端的用户的多个虹膜图像的步骤之后，包括：对所述多个虹膜图像进行归一化处理和图像增强处理。
在该技术方案中，由于在不同的环境下采集的多个虹膜图像的效果是不同的，因此，在采集多个虹膜图像之后对多个虹膜图像进行归一化处理和图像增强处理，避免环境因素(如光照强度)对采集的多个虹膜图像的图像效果产生影响，从而提高虹膜识别效率。
在上述技术方案中，优选地，在所述采集所述终端的用户的多个虹膜图像的步骤之前，包括：判断所述用户是否眨眼睛；在判断结果为是时，执行所述采集所述终端的用户的多个虹膜图像的步骤；否则，提示所述用户眨眼睛以开始虹膜采集。
在该技术方案中，通过检测用户是否眨眼睛，若检测到用户眨眼睛，则开始采集用户的多个虹膜图像，从而避免了用户手动开启开始采集虹膜
的按钮，进而提升了用户体验。当然，也可以在采集多个虹膜图像的过程中，若检测到用户再次眨眼睛，则结束虹膜的采集，从而避免了用户手动触发结束采集虹膜的按钮。
本发明的第二方面提出了一种鉴权装置，用于终端，包括：采集单元，用于采集所述终端的用户的多个虹膜图像；确定单元，用于提取所述多个虹膜图像中的当前虹膜特征点，并根据所述当前虹膜特征点在所述多个虹膜图像中的位置确定所述当前虹膜特征点的当前运动轨迹；鉴权单元，用于根据所述当前运动轨迹与所述当前虹膜特征点对所述用户进行鉴权。
在该技术方案中，通过获取用户的多个虹膜图像中的当前虹膜特征点在多个虹膜图像中的位置来确定用户的当前运动轨迹，其中，当前虹膜特征点可以是虹膜中的裂缝、抗洞等，然后根据当前运动轨迹与当前虹膜特征点对用户进行鉴权，即由相关技术中的静态虹膜图像的鉴权上升到动态的虹膜图像的鉴权，避免了非法用户利用虹膜套进行鉴权来获取访问终端的权限，进一步地保证了虹膜鉴权的安全性，而且也避免了由于用户的虹膜特征点发生改变而导致虹膜鉴权的效率降低，从而保证了虹膜鉴权的可靠性。
另外，由于是对多个虹膜图像中的当前虹膜特征点的动态采样以得到当前虹膜特征点，当前虹膜特征点的数量相对于相关技术中的对虹膜图像静态鉴权时采样的虹膜特征点的数量少，从而可以降低采样的采样时间和等错率。而且当前虹膜特征点的数量的降低使得对鉴权的处理算法的要求降低，鉴权处理的负担也会降低，则减少了鉴权时所占用的资源，从而提高了鉴权效率。
在上述技术方案中，优选地，所述鉴权单元包括：第一判断单元，用于判断所述当前运动轨迹与鉴权运动轨迹是否匹配；所述鉴权单元具体用于，在判断结果为是时，将所述当前虹膜特征点与鉴权虹膜特征点进行对比，若所述当前虹膜特征点与所述鉴权虹膜特征点对比一致，则鉴权成功，否则，鉴权失败并提示所述用户，在判断结果为否时，鉴权失败并提示所述用户。
在该技术方案中，若判定当前运动轨迹与鉴权运动轨迹匹配，且当前
虹膜特征点与鉴权虹膜特征点对比一致时，说明终端的用户为该终端的合法用户，则鉴权成功，可以向该用户开放访问终端的权限；否则说明终端的用户为该终端的非法用户，禁止向该用户开放访问终端的权限，避免了非法用户利用虹膜套进行鉴权来获取访问终端的权限，进一步地保证了虹膜鉴权的安全性。其中，鉴权虹膜特征点可以从预先采集的鉴权虹膜图像中获取。
当然，也可以先将当前虹膜特征点与鉴权虹膜图像中的鉴权虹膜特征点进行对比，若对比一致，再判断当前运动轨迹与鉴权运动轨迹是否匹配。
在上述技术方案中，优选地，所述第一判断单元具体用于，将所述当前运动轨迹与所述鉴权运动轨迹进行匹配，若所述当前运动轨迹与所述鉴权运动轨迹的匹配度大于预设匹配度时，判定所述当前运动轨迹与所述鉴权运动轨迹匹配，否则，判定所述当前运动轨迹与所述鉴权运动轨迹不匹配。
在该技术方案中，由于当前运动轨迹与鉴权运动轨迹很难达到一致，则在当前运动轨迹与鉴权运动轨迹匹配时，根据当前运动轨迹与鉴权运动轨迹的匹配度来判断当前运动轨迹与所述鉴权运动轨迹是否匹配，从而提高了判断虹膜鉴权的可靠性。
在上述技术方案中，优选地，还包括：处理单元，用于对所述多个虹膜图像进行归一化处理和图像增强处理。
在该技术方案中，由于在不同的环境下采集的多个虹膜图像的效果是不同的，因此，在采集多个虹膜图像之后对多个虹膜图像进行归一化处理和图像增强处理，避免环境因素(如光照强度)对采集的多个虹膜图像的图像效果产生影响，从而提高虹膜识别效率。
在上述技术方案中，优选地，还包括：第二判断单元，用于判断所述用户是否眨眼睛；所述采集单元具体用于，在判定所述用户眨眼睛时，执行所述采集所述终端的用户的多个虹膜图像的步骤；提示单元，用于提示所述用户眨眼睛以开始虹膜采集。
在该技术方案中，通过检测用户是否眨眼睛，若检测到用户眨眼睛，则开始采集用户的多个虹膜图像，从而避免了用户手动开启开始采集虹膜
的按钮，进而提升了用户体验。当然，也可以在采集多个虹膜图像的过程中，若检测到用户再次眨眼睛，则结束虹膜的采集，从而避免了用户手动触发结束采集虹膜的按钮。
本发明的第三方面提出了一种终端，包括上述技术方案中任一项所述的鉴权装置，因此，该终端具有和上述技术方案中任一项所述的鉴权装置相同的技术效果，在此不再赘述。
通过本发明的技术方案，可以避免由于用户的虹膜特征点发生改变而导致虹膜鉴权的效率降低，从而保证了虹膜鉴权的可靠性，同时还有效地提高虹膜鉴权的安全性。

2.由于根据当前运动轨迹与当前虹膜特征点进行鉴权时的依赖要素相同，在采样当前虹膜特征点时有效地减少了当前虹膜特征点的采样的数量。
3.由于采样的当前虹膜特征点的数量减少使得虹膜的个人独特特征点比率下降。
4.由于个人独特特征点比率下降使得对鉴权的处理算法的要求降低，鉴权处理的负担也会降低，则减少了鉴权时所占用的资源，从而提高了鉴权效率。
5.根据当前运动轨迹与当前虹膜特征点进行鉴权时，由于避免了相关技术中的采样多个虹膜图像中的所有的虹膜特征点，从而降低鉴权时处理的数据文件的大小。
