Other unit, for when receiving finger print information, identifying the finger print information.
Correspondingly, the present invention provides a kind of fingerprint identification device, further includes：Fingerprint capturer, for receiving finger print information；
Fingerprint extractor, for extracting collected finger print information；Sensor, for receiving physiology signal；Processor, for supervising
It surveys whether the fingerprint extractor receives finger print information, when receiving finger print information, judges whether the sensor receives
To physiology signal, when receiving physiology signal, the finger print information is identified.
The first fingerprint identification method and device provided according to the present invention, monitors whether to receive finger print information first,
When receiving finger print information, finger print information is not identified temporarily, and judges whether to receive physiology signal simultaneously,
Only when receiving physiology signal, the finger print information that user provides just is identified, due to referring to that the material of the duplicate such as mould must
So different from the skin of human body, fingerprint copy cannot provide any physiology signal, thus the present invention can by whether
Physiology signal is received to efficiently differentiate the skin of fingerprint copy and people, prevents erroneous judgement.
Second of the fingerprint identification method and device provided according to the present invention monitors whether to receive Human Physiology letter first
Number, only when receiving physiology signal, just indicate that current touch object is the skin of people, then receives finger print information, into
And finger print information is identified, the material due to referring to the duplicate such as mould is inevitable different from the skin of human body, and fingerprint copy is not
Any physiology signal can be provided, therefore the present invention can be by whether receive physiology signal to efficiently differentiate and refer to
The skin of line duplicate and people prevents erroneous judgement.
Detailed description of the invention

Specific embodiment
It is further described in detail below with reference to embodiment, embodiments of the present invention are not limited thereto：
Embodiment 1：
A kind of fingerprint identification method as described in Figure 1, this method include：
S1：Acquire finger print information：Person to be verified places a finger on the fingerprint capturer for being used to acquire fingerprint of terminal, from
And the fingerprint capturer can collect the fingerprint image of person to be verified.
S2：Take the fingerprint information：Collected fingerprint image characteristics are proposed by fingerprint extractor.
Wherein, the feature may include one or more in following：
Body current signal, human body resistance signal, human body moisture signal and human body temperature signal characteristic.
S3：Judge whether fingerprint capturer receives finger print information by processor according to the feature.
S4：Judge whether to be verified be living body according to the feature, such as the electric current about human body incudes, principle with
The principle of capacitance touch screen is identical, when finger touches on the metal layer of sensor, due to human body electric field, and user and sensor
Surface is formed with a coupled capacitor, and for high-frequency current, capacitor is direct conductor, and then finger siphons away one from contact point
