The device is particularly related to a fingerprint identification device that recognizes whether the source of the fingerprint is a human body. [Prior Art] Techniques for authenticating personal information using the characteristics of the human body have been widely used in various security-related systems, and research and development of fingerprint authentication has been conducted from the past. A technique for authenticating an identity by pressing a finger on the identification wafer is obviously very convenient, but there are also variations and uneasiness in actual operation due to different specific situations. 、 The optical fingerprinting machine on the market is a 2D camera. The optical sensor uses light to change the direction of reflection on the concave and convex surface of the fingerprint to make a private pattern. It is mainly reflected by the concave and convex parts of the finger. The light is imaged by the image pickup unit for lens concentrating 'because the sensor itself is not exposed to the outside', so the durability is high. In the practical application of the technical optical fingerprint identification device, if the wet finger or the dry finger can be used, ν - ^ b θ can not be correctly recognized (the mouth knife # is also used in the instruction manual) In addition, there is also the danger of using artificially manufactured copying fingers. A buckled crystallized pattern to identify success, and in the well-known technique, ^ ^ 攸 ^ side fingerprint on glass and silicone It is undoubtedly a challenge to successfully copy the fingerprints of others ' ^ ^ to ' the fingerprints of the prior art.

Due to the function of the prior art optical fingerprint identification, the manual manufacturing and reproduction appear The fingerprint identification device recognizes the passage, which is said to be a serious threat. In other aspects, the probability of fingerprints leaving a complete fingerprint is low, and often because the softness of the fingers of the person is different, the depth of the fingerprint of the hand is shallow: the same as the 'dry humidity, and so on, which affects the correct identification result. Therefore, in order to solve the above problem of the optical fingerprint identification device, the fundamental improvement of the sensor is improved, and the design of the optical mechanism/the method of fingerprint recognition calculation is relatively matched, and the seven t M" violates the comparative benefit.
