在一些可行的实施方式中，步骤S102可以包括：
判断用户指纹图像是否与预先存储的多个用户指纹图像中的任意一个匹配；
若是，确定用户指纹信息有效；
若否，确定用户指纹信息无效。
本发明实施例中，用户指纹图像包括用户指纹图像中的多条指纹纹路信息、指纹核心点位置、指纹三角点位置等等，判断用户指纹图像是否与预先存储的多个用户指纹图像中的任意一个匹配的方式可以为：判断用户指纹图像中的多条指纹纹路信息与预先存储的多个用户指纹图像中的任意一个预存用户指纹图像中的多条指纹纹路信息匹配，若匹配，确定用户指纹信息有效，若不匹配，确定用户指纹信息无效；和/或，判断用户指纹图像中的指纹核心点位置与预先存储的多个用户指纹图像中的任意一个预存用户指纹图像中的指纹核心点位置匹配，若匹配，确定用户指纹信息有效，若不匹配，确定用户指纹信息无效；和/或，判断用户指纹图像中的指纹三角点位置与预先存储的多个用户指纹图像中的任意一个预存用户指纹图像中的指纹三角点位置匹配，若匹配，确定用户指纹信息有效，若不匹配，确定用户指纹信息无效。
在一些可行的实施方式中，指纹信息包括用户指纹图像和用户指纹取向，步骤S102可以包括：
判断用户指纹取向与预存参考指纹取向是否相同；
若不同，对用户指纹图像进行校准，得到校准后的用户指纹图像；
从校准后的用户指纹图像中提取用户指纹特征；
判断用户指纹特征与预存参考指纹特征是否匹配，若匹配，则确定用户指纹信息有效。
