Biometric input, such as images of a hand obtained by a biometric input device, may be used to identify a person. An attacker may attempt to gain access by presenting false biometric data with an artificial biometric model, such as a fake hand. During a suspected attack, the attacker is prompted for additional data. For example, email address, telephone number, payment information, and so forth. This provides additional information about the attack while prolonging the time spent by the attacker on the attack. Information explicitly indicating failure is delayed or not presented at all. Data associated with an attack is placed into an exclusion list and further analyzed to recognize and mitigate future attacks. A subsequent attempt that corresponds to exclusion data proceeds with presenting prompts, gathering further information and consuming more of the attacker's time and resources.

Aspects of this disclosure relate to a biometric sensing device that combines sensing with an actuator for two way communication between a finger on a surface and the device. The sensor can also function as an actuator. A finger can be authenticated based on an image of the finger generated by the sensor and also based on a response to energy delivered to the finger by the actuator. Two way communication can provide more robust authentication than fingerprint sensing alone.
