Description

Fingerprint print recognizable keyboard

The present invention relates to a keyboard for a computer, and more particularly, to a fingerprint keyboard for preventing leakage of confidential data stored in a computer by a non-registered user with a fingerprint recognition function.

In general, in a situation where the need for security of a computer is increasing day by day, a specific key or a password function is implemented in software to maintain the security of the computer.

However, in the conventional computer security device as described above, every time a computer is used, it is necessary to operate a specific key to check whether the computer is used. At this time, if only a specific key can be known, anyone can use the computer, so it is difficult to maintain complete security. Rather, if a computer user forgets his or her own password, there is a problem that the computer cannot be used even though the computer user has permission to use the computer. In the case of the password input method, security can be easily solved by appropriately combining the number of cases or by inputting an arbitrary password, and a person who does not have permission by stealing or hacking the password by a user with permission. There is also a problem that can easily solve the security network.

In addition, the conventional security system is composed of a system for implementing the security system in software in the state that the main power is already on. However, recently, the population of acquiring computer knowledge is increasing due to the development of computer science, and there is a problem that the software security system is simply destroyed due to the development of hacking technology.

Accordingly, an object of the present invention is to provide a fingerprint keyboard that allows only registered users to use a computer by using a fingerprint recognition method.

1: Key matrix 3: Fingerprint recognition module

In order to achieve the above object, a fingerprint keyboard according to the present invention includes a key matrix unit having a plurality of keys for inputting data into a computer; A fingerprint recognition unit that recognizes a fingerprint of a computer user and determines whether the user is a registered user or a non-registered user and outputs a determination result as a signal; A keyboard controller for processing an input signal when an operator inputs a key of the key matrix unit, and outputting a signal for supplying power to a CPU of the main body when a registered user is corrected as a result of checking an output signal of the fingerprint recognition unit; It is characterized in that it comprises a wired or wireless wired or wireless communication unit for transmitting the output signal of the keyboard controller to the computer main body.

The keyboard controller may encrypt and output communication data in order to prevent hacking of data communicating through the wired communication unit from the outside.

The keyboard controller may be configured to prevent the computer body from being operated by another fingerprint keyboard using a unique ID when communicating with the body.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings. 1 is a plan view and a side view of a fingerprint keyboard according to an embodiment of the present invention, Figure 2 is a block diagram showing the internal configuration of the fingerprint keyboard.

Referring to Fig. 1, there is a general type keyboard, and there is a key matrix 1 on the keyboard. On the far right, there is a fingerprint recognition unit 3 for receiving a fingerprint of a computer user.

Referring to FIG. 2, there is a keyboard controller, and a fingerprint recognition module, a key matrix, and a communication module are located around the keyboard controller.

The fingerprint recognition module recognizes a user's fingerprint and is in charge of only a function of registering, authenticating or updating a new user, and outputs a signal generated in the process to the keyboard controller.

In this embodiment, a fingerprint recognition module called FP-6000 was used. The FP-6000 is stand alone and can store and manage about 500 fingerprints. It operates at DC 5 ~ 11 [V] and is compact. Since the processor is built in itself, the user's identification, modification, deletion, and authentication are all performed, and the fingerprint recognition result is output to the keyboard controller.

Although not shown in FIG. 1 or FIG. 2, the fingerprint keyboard has a power module configured to drive the fingerprint module and the keyboard controller.

As a power source, two 1.5 [V] batteries are used to form a 3 [V] DC power source. The 3 [V] was boosted to 5 [V] or 3.3 [V] to be supplied to the fingerprint recognition module and the keyboard controller. Since the fingerprint recognition keyboard has such a power module, there is no need to receive power from the main body via wires. Thus, it is possible to communicate with the main body in the form of wired or wireless.

In the present embodiment, the FP-6000 fingerprint recognition module is used, but other fingerprint recognition modules may be used without following the present embodiment.

Next, the key matrix is a keyboard keyboard is arranged in the form of a matrix to generate an electrical signal for the key in accordance with the user input. The generated electrical signal is input to the keyboard controller.

Next, the communication module is a configuration for transmitting the various data output from the keyboard controller to the main body of the computer.

In the main body, a separate device for processing the communication data transmitted from the fingerprint keyboard should be configured in advance. That is, there must be a communication port and a communication data processing unit for processing data transmitted from the fingerprint keyboard, and a power control unit for controlling power applied to the CPU of the main body. As will be described later, when the user is authenticated through the fingerprint recognition module, the keyboard controller outputs a wake-up signal to the computer main body and supplies power to the main CPU of the main body. When the main CPU powers up, the computer will boot. As a result, the fingerprint keyboard according to the present invention must be authenticated to boot the computer.

As described above, the fingerprint recognition keyboard uses its own power source rather than the power source of the computer main body, so that the communication module can be configured in a wired or wireless form. When configured in a wireless form, it is possible to configure the method using infrared and the method using RF.

Next, the keyboard controller controls the entire fingerprint fingerprint keyboard. 3 is a flowchart illustrating the operation of such a keyboard controller.

Referring to Figure 3, once, the keyboard controller checks whether the system and the battery is normal (S1, S2). If the check result is normal, the communication module is initialized (S3), otherwise it displays an alarm or warning and terminates. (S9)

After initializing the communication module, check whether there is keyboard input from the key matrix. (S4) If there is keyboard input, the keyboard processing program is executed. (S5) If there is no keyboard input, next, check whether there is a fingerprint input. (S10) If there is a fingerprint input, a fingerprint recognition processing program is executed. (S11)

The data generated according to the execution of the keyboard processing program and the fingerprint recognition processing program is then encrypted to generate communication data (S6). A communication data processing program for transmitting the communication data to the computer main body is executed (S7). Output communication data in the form of wire or wireless. (S8)

The encryption process is a step for preventing the data output through the communication module, that is, the communication data from being hacked from the outside. When encrypted, a unique ID for each fingerprint keyboard is added to form communication data.

The ID is for preventing manipulation of the main body of the computer using another fingerprint recognition keyboard, and the main body is formed in advance with the fingerprint recognition keyboard to have a unique ID. Therefore, the main body checks the ID of the data transmitted from the fingerprint keyboard and receives the communication data in the case of the registered ID, and ignores the communication data in the case of the non-registered ID.

Next, Figure 4 is a flow chart of the fingerprint recognition process using the fingerprint recognition module. Referring to Fig. 4, once, the system and the battery are checked (S21). The system and the battery are checked (S22). If normal, the communication port is initialized and the fingerprint recognition module is turned on (S23). The fingerprint is scanned (S24), and the scanning data generated as a result of the scanning is checked whether or not the registered user. (S25, S26) In the case of the fingerprint of the registered user as a result of the scanning, the fingerprint recognition module is used by the keyboard controller. Output the authentication signal (S27).

The output user authentication signal is input to the keyboard controller, and the keyboard controller receiving the user authentication signal outputs a wake-up signal for applying power to the CPU of the main body to the computer body through an encryption process. The wake-up signal is input to the communication data processing unit of the main body as described above, and the communication data processing unit supplies power to the CPU of the main body through the power control unit to boot the main body.

When the console boots up, the user can use the computer. If you leave the computer for a while while the computer is in use, the computer will automatically enter the security mode, that is, screen saver mode. At this time, the fingerprint keyboard automatically enters the security mode. The user who has returned to his / her seat must go through the fingerprint recognition process again to use the computer again. At this time, since the computer is already booted, the communication data processing unit in the main body outputs the security mode release signal of the computer to cancel the screen saver mode, and displays the previous work screen on the monitor. Thus, the user can continue working.

As described above, the fingerprint recognition keyboard according to the present invention has a fingerprint recognition module embedded in the keyboard to boot a computer after user authentication is performed through fingerprint recognition. Therefore, since the user does not need to remember and input the password unlike the conventional art, there is no fear of forgetting the password, and the unauthorized use of the computer can be prevented.
