Processing method and device for detecting fingerprint

The invention discloses a processing method and a device for detecting fingerprint, which are used for realizing fingerprint false touch and reducing the processing after false touch. The method comprises the following steps of: receiving a trigger operation of an organism through a fingerprint identification area; Performing fingerprint identification on the organism; detecting whether a signal change value of an auxiliary touch area other than the fingerprint area exceeds a preset channel threshold value when a fingerprint identification error occurs; when the signal change value of the auxiliary touch area exceeds the preset channel threshold value, the process triggered by the fingerprint identification error is masked. 本公开是关于种检测指纹的处理方法及装置，用于实现指纹误触，减少误触后的处理。所述方法包括：通过指纹识别区域，接收生物体的触发操作；对所述生物体进行指纹识别；在指纹识别错误时，检测所述指纹区域以外的辅助触摸区域的信号变化值是否超过预设的通道阈值；在辅助触摸区域的信号变化值超过预设的通道阈值时，屏蔽指纹识别错误所触发的处理。
