提供减少的等待时间的指纹认证系统和方法
Abstract:
获取(106)指纹图像，并且确定(110)手指(15)是否仍在触摸感测表面。当手指(15)不再触摸感测表面时，基于到目前为止获取的一个或多个指纹图像来对用户进行认证(112)。当确定了手指(15)仍然触摸感测表面时，确定(114)指纹图像的质量量度。当质量量度指示指纹图像的质量满足预定质量标准时，基于到目前为止获取的一个或多个指纹图像来对用户进行认证。当质量量度指示指纹图像的质量未能满足预定质量标准时，获取后续指纹图像。当手指(15)仍然触摸感测表面、并且质量量度指示后续指纹图像的质量满足预定质量标准时，基于包括后续指纹图像的到目前为止获取的一个或多个指纹图像来对用户进行认证。
Abstract(English):

A fingerprint image is acquired, and it is determined if the finger is still touching the sensing surface. When the finger no longer touches the sensing surface, the user is authenticated based on one or several fingerprint image(s) acquired so far. When the finger still touches the sensing surface, a quality measure is determined for the fingerprint image. When a quality of the fingerprint image fulfills a predefined quality criterion, the user is authenticated based on one or several fingerprint images acquired so far. When the quality of the fingerprint image fails to fulfill the predefined quality criterion, a subsequent fingerprint image is acquired. When the finger still touches the sensing surface, and the quality measure indicates that the quality of the subsequent fingerprint image fulfills the predefined quality criterion, the user is authenticated based on one or several fingerprint images acquired so far including the subsequent fingerprint image.
