2 is a circuit diagram illustrating a security device of a computer network system according to another exemplary embodiment of the present invention.

The present invention relates to a lock security system using a password, and more particularly, to access / exit / access a computer, a safe, a hotel, a general home, a telebanking, etc., where security is required by using an input time difference between each character of the password. The present invention relates to a general-purpose computer hacking prevention and electronic / mechanical password lock security system using a difference in input time between character information.

Conventional passwords (PASSWORD) has been composed of letters, numbers or symbols, and can only be accessed to the security target device or the system if their contents and arrangement are the same as the password previously stored by the user.

In the case of such a security target device, when the number of characters of the password is small, there is a big problem of security that the connection can be easily made by only a plurality of repetitions. In addition, accidental passwords were frequently discovered by accident. For this reason, the recent bank telebanking system also prohibits the use of a user's social security number or birth date as a password.

In particular, with the development of high-performance computers, various combinations of passwords applied to computers have been repeatedly implemented for security systems in a short time.

In order to improve the security of a security device or system, a method of simply increasing the number of characters of a password or mandatory symbol in the middle of a password has been required from a device manager or a system manager. In the case of the computer network system, a hacking is prevented by encrypting information coming and going from the network by applying a random number generation technique encryption technique.

For security systems such as military closed computer systems, central banks of large banks, or the nation's first-class information handling agencies that require extreme security, security techniques such as fingerprint recognition and eye recognition based on pattern recognition technology are used because of the password loophole. There is a situation. In this case, there is a problem that a relatively large cost is required to design and manufacture such a security facility.

The present invention has been invented to improve the above-mentioned problems of the conventional security technology, by simultaneously setting the time information between input characters as well as characters including numbers when setting a password in a security device that requires security of the security device. It is possible to maximize the security of the security device by simultaneously checking the time information between input characters as well as the input characters when entering the password to unlock the general purpose computer hacking prevention by using the input time difference between each character information. And an electronic / mechanical password lock security system.

A general purpose computer hacking prevention and electronic / mechanical password lock security system using an input time difference between each character information of a password for realizing the above object is a sequential comparator 14 which sequentially compares an input password and a stored password. A storage device (12: EE2PROM) for storing and changing an existing password, a timer 15 for outputting an existing password according to predetermined time information, a clock / oscillator 16 for generating basic time information of the system, input On-demand semiconductor 10 composed of an input buffer 13 (FIFO) that accepts a password and sends it to the sequential comparator 14 according to time information, and a controller 11 that oversees the above functional blocks. Is done.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a circuit diagram of a mechanical security device according to an embodiment of the present invention. The lock security system of the present invention is a mechanical security device, wherein a user inputs a password from a keypad input unit 18 to an on-demand semiconductor 10. The input and the LCD (LIQUID CRYSTAL DEVICE) is configured to be displayed on the display unit 17, the on-demand semiconductor 10 checks the time information between the input characters with the character information when entering the user's password and the security of the door, etc. according to the result It is a password lock security system that can open and close the device (not shown).
First, when the user inputs the corresponding password to the keypad input unit 18, the user presses the password change button, and then inputs a new password to the controller 11 of the on-demand semiconductor 10 at an arbitrary time interval. Is stored in the storage device 12 (EE2PROM). In order to open a security device such as a door at a later use, the user inputs a password into the input buffer 13 of the custom semiconductor 10 through the keypad of the keypad input unit 18.
The controller 11 has a memory device 12 through an address, a password data and a write, a timer 15 through a time data, and an input buffer 13 through a FIFO (FIRST-IN FIRST-OUT) control. It is connected. The timer 15 is connected to the memory device 12 and a read strobe is connected to the controller 11. The controller 11 and the input buffer 13 are connected to each other through the clock / oscillator 16. ) Are connected to each other. In addition, the sequential comparator 14 is connected to the memory device 12 and the input buffer 13 to the input side, respectively, and the output signal is output from the controller 11 and the application specific semiconductor 10 by unlocking or not. have.
The input buffer 13 synchronized according to the clock of the clock / oscillator 16 inputs an input value when the keypad of the keypad input unit 18 is pressed into the input buffer 13 and the next character is pressed. The time it takes to enter the information by a certain rule. When the input is started and the password is input, the controller 11 receives the password previously input into the storage device 12 and the time information (lead strobe) mechanically set by the timer 15, and reads the password in a predetermined order. The input password, which is data stored in the buffer 13, and the two passwords are compared in the sequential comparator 14.
If a time error or character symbol error occurs between the already input password and the input password, the sequential comparator 14 turns out to be false and prohibits the opening and closing of the password to the LCD display unit 17 through the controller 11. It shows that it is a device for notifying access.
Therefore, the present invention provides a device that requires security when setting a password for determining whether to permit access / exit / open / close of computers, safes, hotels, homes, and telebanking that require security on the output side of the on-demand semiconductor 10. In addition to conventional character (or numeric or symbolic) information, several user-adjustable characters can be arbitrarily adjusted through the board, including a simple time control hardware in it, and an ASIC that uses software of the existing password verification operating system. By giving the maximum and minimum time limit information, you can prevent hacking of all computer-related systems and improve the security of mechanical systems.
