Description
Technical field
The present invention relates to a kind of authentication method and tripper of the multistage authentication system for unlocking based on fingerprint and softdog.
Background technology
Smartcard encrypts lock is a kind of software protection model, and principle of work is: by partial code in software through compiling, and " transplanting " is inner to encryption lock hardware, and code deletion corresponding in software.The code of the key of terminal application software and data realize hiding, and key code is placed in encryption lock hardware and protects.When needs use, then from smart card, key code and data taken out and apply, thus realizing the whole function of whole software.Reach effective raising of the safe class of encryption.Current intelligence mainly contains following two kinds of modes: one, be integrated on car key by remote controller and projector, key can send infrared signal, realizes opening and closing the equipment such as lock and car door, baggage container, skylight.Two, automobile intelligent keyless access system is called for short PKE(PASSIVEKEYLESSENTER); have employed RFID wireless radio-frequency and testing vehicle register code recognition system; command and control system and keyless systems are merged; both traditional vehicle circuitry protection had been remained; achieve again double anti-theft protection, for car owner provides convenient and safety to greatest extent.The cost that these two kinds of modes realize is not high, but all cannot realize the re-authentication of identity, is only safe not with automobile key identification car owner; Unblank actually also or the unconscious pressing of None-identified is conscious in addition, car can not be avoided by unconscious operation of opening.Therefore, above-mentioned two schemes is safe all not.Fingerprint recognition system, the complexity of fingerprint is enough to the enough features being provided for differentiating, meeting in unique situation, very convenient to carry.Along with the progress of fingerprint identification technology, fingerprint recognition speed is fast, and accuracy is high, the collection of fingerprint and judge that effect is fine, fingerprint collecting and means of identification cheap, outward appearance is small and exquisite, be all that the identification of automobile key integrated fingerprint provides convenience.Fingerprint, as a part for human body, has and not easily loses, easy to carry, and without the need to memory, fingerprint characteristic is obvious, has repeatability low, not easily the feature such as stolen, is failure-free using fingerprint recognition as accreditation.The fingerprint automobile key occurred on the market, be mostly to use DSP or ARM process, power consumption and Portability all also exist deficiency.And process interim borrow car time inconsiderate, be unfavorable for the popularization and application of fingerprint key.
Summary of the invention
The object of the present invention is to provide a kind of automobile remote-control key and method of work thereof of multistage authentication, overcome existing automobile remote-control key and easily unlock by button by mistake and borrow the awkward shortcoming of car temporarily.
An automobile remote-control key for multistage authentication, is characterized in that: in automobile solution lock unit, add identification authenticating unit, realizes completing different authentications in different modes; When pattern zero, without the need to authentication, directly can use a teleswitch and open automobile lock, regression is general-utility car key; When other mode situation, if in fingerprint authentication pattern, only need can unblank through fingerprint authentication; If under softdog pattern, under only needing checking softdog pattern, checking softdog is only needed to unblank; If when softdog and fingerprint exist simultaneously, Dietary behavior selection mode; Comprise with lower module, all modules are all connected with processing unit;
A, processing unit module: the micro controller system of super low-power consumption is main body, for completing the request of data of module b ~ f and returning;
B, coded excitation module: realize transmission requests unlocking code;
C, keystroke handling module: mainly comprise button pretreatment and keyboard portion;
D, Fingerprint Processing Module: comprise fingerprint sensor and finger prints processing part, for fingerprint collection and compare;
E, softdog module: for providing the data of checking softdog;
F, memory module: for the finger print data of storage of collected are mobile phone memory card;
G, power unit: provide working power for above each unit.
A kind of automobile remote-control key of multistage authentication, it is characterized in that: by increasing a switch S 1 inside key rotating shaft, unlocking automobiles key is become transparent material, place a fingerprint recognition and harvester Finger1 below, side increases a USB interface, finger print data is imported by PC, when softdog module and Fingerprint Processing Module are applied simultaneously, can arrange and whether cancel authentication selection, when borrowing car if there is there being people, softdog can be added, arrange in the set time without the need to checking, change key into normal key to use.
An automobile remote-control key method of work for multistage authentication, comprises the following steps:
Step 1, presses the button and is opened by key;
Step 2, if during employing fingerprint checking, obtain the finger print data of fingerprint sensor, use special finger prints processing to process fingerprint; If when using softdog checking, obtain softdog, use softdog verification process;
Step 3, according to the process of step, is proved to be successful, then starts keypress function;
Step 4, the button result of processing unit receiving step 3, determines whether send concrete signal to coding module;
Step 5, coding module starting transmitter module, transmitting control signal, for unlocking automobile component to automobile after receiving the coding instruction of processing unit.
Fingerprint identification technology and softdog technology are applied on automobile remote-control key by the present invention, use special fingerprint identification module, by increasing by two kinds of identification authentication mode, replace existing simple dependence button trigger circuit, user only has by after authentication, could start key circuit, button could propose encode request to processing unit.The present invention is not when changing existing automobile key distant control function, by installing fingerprint identification module and softdog two kinds of verification modes in key, not only can increase substantially safety and the confidentiality of automobile key, avoid button by mistake to unlock automobile, and it is more lasting to realize service time of battery by specific power save mode.Even if can key loss be realized, also can ensure the safety of automobile, people can also be solved and borrow the trouble managing fingerprint during car temporarily.
