Description

The fingerprint card reader

The utility model relates to the card reader technical field.

Magnetic card of the prior art, normally encrypt with the method that adds digital password, the holder in use, magnetic card was brushed on card reader, read the account number of card stored, be transferred in the database in the computer system, correspondence is found out the predefined password of user, the password of this password and holder input is compared, give operating right after correct.Modern society, magnetic card by more and more widely be applied to various aspects, but in actual use, the magnetic card part that also comes with some shortcomings, the numerical ciphers that mainly is magnetic card is broken easily, therefore usually cause damage to the holder, developing magnetic card that a kind of password is difficult for being broken, just day by day to become society required.Research by analysis, we think, the somatic fingerprint password is reliable, because people's fingerprint has uniqueness, if holder's finger print information is stored in the database, corresponding with the account of oneself, so, except that the holder, anyone is difficult to use this magnetic card by breaking through password.Just we still lack and a kind ofly can be stored in the device that compares use in the database with the cardholder account after the finger print information acquisition process with the people.

The purpose of this utility model provides a kind of just and the somatic fingerprint information acquisition can be stored in the database in order to solve the deficiencies in the prior art, with when card, database of fingerprint information is accessed the fingerprint card reader that the finger print information with holder's input compares.

The purpose of this utility model is achieved by the following technical solution.

This fingerprint card reader is to have the fingerprint collecting window on the surface of its shell, is provided with the fingerprint collecting processing module in card reader inside, and the fingerprint collecting processing module is provided with fingerprint sensor, and fingerprint sensor exposes by the fingerprint collecting window.

On the described fingerprint collecting processing module except that being provided with fingerprint sensor, also be provided with storer, address latch and CPU, between fingerprint sensor and storer, between fingerprint sensor and the CPU and all be connected with data line and address wire between address latch and the CPU, be connected with address wire between address latch and the storer; Described fingerprint sensor is the semiconductor fingerprint sensor.

Be provided with fingerprint sensor owing to be arranged at the finger print acquisition module of card reader inside, fingerprint sensor exposes to the fingerprint collecting window of card reader shell again.During hair fastener, the user will point after brushing magnetic card on the card reader by on fingerprint sensor, the fingerprint collecting processing module is read (collection), handles, encrypts and is stored user's fingerprint, form personal information, and it is stored in the terminal database, corresponding with holder's account.When using magnetic card,, be by the fingerprint collecting processing module reality to be adopted living body finger print information to be sent in the database, compare, realize the authentication of user real identification with the corresponding finger print information of card account to the identification of user's identity.

Fingerprint sensor on the Fingerprint Processing Module is sent to the finger print information that collects among the CPU by data line, CPU calculates the signal data of receiving and handle, then with the data storing after these computings in database, depositing the control program that contains various disposal routes in the storer, when needs call these programs, can visit and call by storer being carried out addressing; Fingerprint sensor adopts the semiconductor fingerprint sensor to be because its volume is little, low in energy consumption, not fragile, cost is low, and this also is the direction of world today's sensor technology development.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is the A-A cut-open view that the utility model master looks,

Fig. 2 is a vertical view of the present utility model,

Fig. 3 is the circuit diagram of fingerprint acquisition processing module in the utility model.

The utility model can be reequiped with general on the market card reader, also can oneself redesign and produce.As shown in Figure 1 and Figure 2, do not change the inner structure of former card reader, in card reader, install and put fingerprint collecting processing module 7, be connected with data line 13 with power lead 12 between fingerprint collecting processing module 7 and the card reader circuit board 2, also connecting an output line 5 on the fingerprint collecting processing module 7 links to each other with main frame, on card reader shell 1, offer a fingerprint collecting window 6,, be convenient to user's finger touch with image data so that the fingerprint sensor 8 on the Fingerprint Processing Module 7 exposes.In the circuit of fingerprint collecting processing module as shown in Figure 3, fingerprint sensor 8, storer 9, address latch 10 and CPU11 are arranged, between fingerprint sensor 8 and the storer 9, between fingerprint sensor 8 and the CPU11 and all be connected with data line and address wire between address latch 10 and the CPU11, be connected with address wire between address latch 10 and the storer 9.Fingerprint sensor 8 is main as gathering finger print information, constitute Single Chip Microcomputer (SCM) system by storer 9, address latch 10 and CPU11, finish catching image, processing, encryption, pseudo-finger mark detection, registration, fingerprint template management, checking, discern and communicate by letter, and the computing machine that links to each other is mainly used in the high speed processing and the storage of information.During use, magnetic card was brushed from the groove 3 of swiping the card, the user will point a little on fingerprint sensor 8, sensor is sent to CPU11 with the finger print data information that collects by data line, CPU carries out after the computing transmission with the information of receiving and is stored in the database, corresponding one by one with the account number that obtains of swiping the card, form personal information, can visit and call by storer being carried out addressing at the data processor of storer 9 stored.In the practical application, when carrying out the identity identification, by fingerprint sensor the living body finger print information that collects is sent to finger print information corresponding with the brush card account in the database and compares, to distinguish the legitimacy of user identity.For the ease of using, still can keep the input digit pin mode of former card reader, keep enter key 4, make this card reader can adopt the finger print identifying mode, also can adopt the numerical ciphers authentication mode.

Because each one difference of people's fingerprint, refer to differently, can't forge, make the utility model combine with magnetic card technique, improved the safe reliability of magnetic card greatly.The utility model is simple in structure, be easy to make, cost is lower, safe and reliable, convenient and practical.The utility model can be widely used in the authentication of validated user such as data access, secret key management in authority setting, ecommerce and the E-Payment of banking system, network communication, data base administration and work attendance, gate control system etc., comprises the application of industry important system such as computer system, internet, e-commerce system, government, intranet system manager's authentication and finance, insurance, security and the office worker of department empowerment management, stock exchange, credit card user, beneficiary's authentication etc.

The utility model had both been realized the true identity authentication of personage's unification, had satisfied the demand of various application to data carrier again, was to guarantee the equipment that information security is the most reliable and practical with the soft or hard associated methods.
