Embodiment
Embodiment of the invention solution mainly is that the palmmprint recognition technology is applied to hand-held mobile terminal, realizes carrying out anywhere or anytime the palm print identity identification of arbitrary shape and posture, to improve security and user's ease of use of gate control system.
Gate control system comprises that common gate control system and other need carry out system that identification unblanks such as identity of automobile recognition system etc. in the embodiment of the invention; In the present embodiment terminal can for handheld terminal such as portable terminals such as mobile phones.
As shown in Figure 1, one embodiment of the invention proposes a kind of authentication method for unlocking based on palmmprint, comprising:
Step S101, portable terminal obtain user's palmprint image;
Portable terminal has display interface and camera function in the present embodiment, utilizes portable terminal and combines the palmmprint recognition technology to realize the identification to gate control system.
Particularly; Store the authenticate key of user's palm print characteristics in the portable terminal local data card in advance; This authenticate key can be taken in real time through camera by portable terminal obtain and be stored in this locality, also can from camera etc. has the external unit of camera function, be obtained by portable terminal.Wherein, palm print characteristics can be user's a whole palm, also can be the part of whole palm, such as some or two or more fingers, and perhaps centre of the palm etc.
When user's hand-held mobile terminal was opened the gate inhibition, portable terminal passed through display interface to user prompt palm posture, the palm posture that this palm posture is adopted when for the user authenticate key being set; Certainly, in order to improve the security of gate control system, portable terminal also can be provided with another kind of prompting mode, and not to which kind of palm posture of user prompt, and the user need remember the own initial palm posture that is provided with.For the wrongful user of malice, then possibly be moved terminal authentication because of the palm fault is illegal user, therefore can't open the gate inhibition.
In the present embodiment, after the user made corresponding palm posture according to the interface prompt of portable terminal, portable terminal obtained user's palmprint image through camera.So that follow-up palmprint image to the user carries out authentication.
Step S102 handles palmprint image, obtains the palm print characteristics parameter;
Portable terminal need be handled palmprint image after getting access to user's palmprint image accordingly; This processing comprises: to palmprint image position, cut apart, normalized pre-service; And the Filtering Processing after the pre-service, finally therefrom extract the palm print characteristics parameter, be authenticate key such as the forefinger fingerprint that preestablishes with user's palm; Then after portable terminal gets access to user's palmprint image; Through after above-mentioned pre-service and the Filtering Processing, therefrom extract user's forefinger fingerprint characteristic parameter, so that follow-uply user identity is carried out authentication according to this forefinger fingerprint characteristic parameter.
Step S103 carries out authentication according to palm print characteristics parameter and local data base to the user;
Step S104, after authentication was passed through, the indication gate control system was unblanked.
Among above-mentioned steps S103 and the step S104, portable terminal compares user's palm print characteristics parameter that extracts and the authenticate key that is stored in the local data base; When the palm print characteristics parameter is consistent with authenticate key, authentication success; Otherwise, authentification failure.
If authentication success, portable terminal is sent to gate control system through the unlocking signal of wireless transmission method after with authentication success.After gate control system receives the unlocking signal of portable terminal transmission, open gate inhibition's lock after the process affirmation is errorless.
Present embodiment user hand-held mobile terminal is support, and combines existing ripe palmmprint recognition technology, realizes carrying out anywhere or anytime the palm print identity identification of arbitrary shape and posture; It is good to have real-time; The identification error rate is low; Strong robustness, advantages such as favorable expandability, the security that has not only improved gate control system; And for the user brings convenience, and can be widely used in common door access control system and other and need carry out system that identification unblanks such as in the systems such as identity of automobile identification.
As shown in Figure 2, another embodiment of the present invention proposes a kind of authentication method for unlocking based on palmmprint, on the basis of the foregoing description, before step S101, also comprises:
Step S100, portable terminal is gathered user's palm print characteristics and is kept at local data base as authenticate key.
The difference of present embodiment and the foregoing description is that in the present embodiment, portable terminal self as authenticate key, and remains on local data base through the first-class collection user's of shooting palm print characteristics.
Carry out key when being provided with at initial user; Palm posture when portable terminal prompting user is provided with authenticate key; And therefrom collect user's palm print characteristics,, and remain in the local data base as authenticate key such as the fingerprint of the forefinger fingerprint of gathering the user or forefinger and two fingers of middle finger.
As shown in Figure 3, one embodiment of the invention proposes a kind of authentication based on palmmprint and unblanks to comprise at the terminal: image collection module 301, image processing module 302, authentication module 303 and gate inhibition's control module 304, wherein:
