The present invention relates to a system and method for double lock release lock using a public telephone network. More specifically, a method of directly inputting an authentication signal such as a password through an input device connected to the locking member when unlocking a locking member such as a lock mounted on a locking device such as a safe and a public telephone network. (PSTN; Public Switched Telephone Network) Performs a method of remotely transmitting and inputting an authentication signal for unlocking the locking member by authenticating all signals obtained therefrom, and then unlocking the locking device with one-time authentication by unlocking the locking device. The present invention relates to a redundancy lock system and method using a public telephone network, which improves security than a case where a lock is released.

In general, the safe (金 庫) is a box provided with a locking member to safely store money, valuables, important documents, etc., is made of steel to prevent easy breakage. Such safes are usually provided in banks to store money or gold bars entrusted by customers or companies. Today, these safes are also available in homes and offices, where they can be used to store cash or important documents.

These safes include fireproof safes, heavy safes, special purpose safes, iron safes, data safes and gallery safes.

A fireproof safe is a fireproof safe that protects various important documents such as deposit accounts, wills, insurance certificates, pension certificates, seal documents, securities, tax data, and passports from fire in case of fire. In addition, the strong safe refers to a safe with anti-corrosion power that can safely store the contents contained therein by preventing the safe from being damaged from external impactors such as drills, hammers, welding, and the like. These strong safes are mainly used to store cash or precious metals to prevent theft, and to increase the anti-corrosion power depending on the thickness of the steel plate used for the inner wall of the safe and the opening and closing device (door) and the performance of the internal fillings. do.

Special-purpose safe is a fireproof safe that has both fire and anti-theft protection by installing an anti-theft safe inside the fire safe. These special purpose safes are double safes used to store drugs in hospitals and the like. In addition, the iron safe is a safe that performs only a simple storage function, the price is very low but is vulnerable to the prevention of fire or theft.

A data safe is a safe that holds things that can be easily damaged or that requires careful precautions such as scratch prevention. A data storage device contains auxiliary storage devices such as magnetic tape, magnetic disk, floppy disk, and optical disk, which store important computer data or data. Can be archived. The gallery safe is a safe for storing goods affected by the surrounding environment such as humidity and temperature, and paintings such as oil paintings and antiques are stored.

However, in the conventional safe, it is common to release the safe by directly inputting an authentication signal such as a password to the input device connected to the locking member when unlocking. However, in such a case, if the authentication signal is exposed to the outside, it is defenseless to the vault release. For example, when a user inputs a password as an authentication signal through a keypad, when another person confirms this, the user cannot prevent the safe from being released by the other person. In addition, when a fingerprint is used as an authentication signal, when another person acquires the fingerprint, the safe is not blocked.

On the other hand, there have been cases where a radio signal is used as an authentication signal for unlocking a safe. In this case, it is inconvenient to separately provide a device for inputting a radio signal, which causes a disadvantage in economic aspects such as a cost burden. In addition, when the authentication signal input through the wireless signal input device is transmitted through the wireless communication network exposes a problem that can be easily hacked. In addition, when an interference signal of the same frequency is generated when the authentication signal is input through the wireless signal input device, the input itself may be impossible.

On the other hand, conventionally, in order to prevent the wireless signal containing the authentication signal from being hacked, there was a case where the wireless signal is encrypted and then transmitted. In this case, the device receiving the radio signal decrypts the encrypted radio signal and then authenticates it. However, in this case, a separate encryption device must be provided in the wireless signal input device, and a inconvenience that a separate decryption device must be provided in the wireless signal receiving device occurs. In addition, the cost burden due to such a separate device is generated.

On the other hand, there was a case where the authentication signal for unlocking the safe is transmitted through a general PSTN network or the Internet network. However, in the case of transmitting the authentication signal through the Internet network, it is difficult to use universally because the device performing such a function is expensive. In addition, when the authentication signal is transmitted through the PSTN network, the signal may be hacked while the signal is being transmitted. When the line connected to the PSTN network is disconnected, it is impossible to transmit the authentication signal itself.

In order to solve the above problems, the present invention provides a method of directly inputting an authentication signal for releasing a locking member through an input device connected to the locking member when releasing a locking member mounted on a safe and an authentication signal using a public telephone network. Simultaneously execute the method of remotely transmitting and inputting all the signals acquired therefrom, and then unlock the lock device and unlock the lock using the public telephone network, which improves security than the case of unlocking the locking member by one-time authentication. It is an object of the present invention to provide a system and a method thereof.

In addition, the present invention, in addition to the direct input of the authentication signal to the input device connected to the locking member when unlocking the locking member mounted on the safe, it transmits the authentication signal through the public telephone network that is mechanically secured safe even at low cost The object of the present invention is to provide a redundancy lock system and method using a public telephone network capable of solving the problem.
