Abstract
The utility model relates to a fingerprint keyboard. A fingerprint collecting and processing module (5) is arranged in a keyboard; the fingerprint collecting and processing module is provided with a fingerprint sensor (6); the fingerprint sensor (6) is exposed on the surface through a fingerprint collecting window (7) on the casing (1) of the keyboard. The utility model has the advantages of easy fabrication, low cost, small volume, low power consumption, high resistance to vibration, high safety, high convenience, high practicability, etc.
Description
The utility model relates to the computer keyboard technique field.
Computing machine of the prior art all is to adopt the password authentication user, because password easily is broken, easily forgery, usually cause the secret that stores in the computing machine illegally to be stolen, though computer elites have spent a large amount of energy and fund to research and develop new precautionary technology and measure, nearly all research and development starting point all is to be placed on the software engineering, does not also have any method to solve the problem that the computing machine password is illegally broken through by efficiently and effectively at present.We expect fingerprint identification technology is applied to authentification of user in the computer technology thus, gather user fingerprints and are stored in the computing machine by a kind of special keyboard, and the operation of computing machine must be through just carrying out after the user fingerprints authentication from now on.And also do not have the suitable keyboard of technology therewith in the prior art, limited the application of computer user's fingerprint recognition authentication techniques.
The purpose of this utility model provide in order to overcome weak point of the prior art just a kind of can gather the user fingerprints data and it is handled after be stored in the computing machine, at the later operation of the computing machine keyboard by finger print data authenticated identity in service.
The purpose of this utility model is achieved by the following technical solution.
The inside of this fingerprint keyboard is provided with the fingerprint collecting processing module, and this fingerprint collecting processing module is provided with fingerprint sensor, and fingerprint sensor exposes to the surface by the fingerprint collecting window of being located on the keyboard case.
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 the 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; On finger print acquisition module, also be provided with the interface circuit that is connected with keyboard pcb; Described fingerprint sensor is the semiconductor fingerprint sensor.
Be provided with fingerprint sensor owing to be arranged at the finger print acquisition module of keyboard, fingerprint sensor exposes to the fingerprint collecting window of keyboard case again, when the user will point by on the fingerprint sensor on keyboard the time, the fingerprint collecting processing module is read (collection), handles, encrypts and is stored user's fingerprint, form personal information, carrying out identity when assert, the finger print information that collects and the corresponding data of storage are being compared to distinguish the true from the false by Fingerprint Processing Module.
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 computing machine, 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.The interface circuit that is connected with keyboard pcb that is provided with on finger print acquisition module can all be sent to computing machine by keyboard chord with the information data of finger print acquisition module and keyboard pcb; Adopting the semiconductor fingerprint sensor to be because its volume is little, low in energy consumption, not fragile, cost is low, 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 Processing Module in the utility model.
We can reequip with general on the market keyboard, also can oneself redesign and produce.As shown in Figure 1 and Figure 2, do not change the inner structure of former keyboard, in keyboard an isolation location-plate 12 is installed, put fingerprint collecting processing module 5 in order to install, be connected with data line 13 and power lead 14 between the interface circuit 11 that contains on keyboard pcb 2 and the fingerprint collecting processing module 5, also be connected with the keyboard chord 3 that links to each other with main frame on the finger print acquisition module 5, on keyboard case 1, offer one and get finger window 7, so that the fingerprint sensor 6 on the Fingerprint Processing Module 5 exposes, be convenient to user's finger touch with image data.In the circuit of fingerprint collecting processing module 5 as shown in Figure 3, fingerprint sensor 6, storer 8, address latch 9 and CPU10 are arranged, between fingerprint sensor 6 and the storer 8, between fingerprint sensor 6 and the CPU10 and all be connected with data line and address wire between address latch 9 and the CPU10, be connected with address wire between address latch 9 and the storer 8.Fingerprint sensor 6 is main as gathering finger print information, constitute Single Chip Microcomputer (SCM) system by storer 8, address latch 9 and CPU10, 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.Also can be provided for connecting the interface circuit 11 of fingerprint collecting processing module 5 and keyboard pcb,, and not need between keyboard and computing machine, to be connected many lines so that all data-signals all send computing machine to by keyboard chord 3.During use, the user will point a little on fingerprint sensor 6, sensor is sent to CPU with the data message that collects by data line, CPU carries out after the computing transmission with the information of receiving and is stored in the computing machine, form personal information, can visit and call by storer being carried out addressing at the data processor of storer 8 stored.In the practical application, carrying out identity when assert, the corresponding data that stores in the finger print information that collects and the computing machine is being compared to distinguish the legitimacy of user identity by fingerprint sensor.
Because each one difference of people's fingerprint, refer to differently, can't forge, make the utility model combine and have very reliable security with computing machine, computer cryptography can not be decoded by illegal person, and the secret in the machine is difficult to be revealed.The utility model is easy to make, cost is lower, volume is little, low in energy consumption, anti-seismic performance good, safe and reliable, convenient and practical.The digitizer that it is built-in can directly be exported digital signal.The utility model can be applicable to following field: the login of WINDOWS security of system, hard disk, database, application program, file and document are enabled management, the operator's rights managements at different levels of ERP management system, office automation system authentication, the financial software operator manages and other need the system of secure log.
