Description

How to issue electronic money through gold coin recognition

The present invention relates to a method of issuing a new electronic money with real security, and to converting and issuing a real gold coin and converting it into electronic money.

Virtual-Currencies, represented by Bitcoin, have a common type of transaction book called Blockchain.

As an overview, a general user downloads a wallet program of electronic money to his computer. Then install it on your computer. The program then runs and starts to synchronize (match) the blockchain with itself and the network. Because the data can reach tens of gigabytes, it usually takes three to seven days. After the synchronization, you can create your own address (the concept of an account at the bank) in your wallet and send or receive Bitcoin via that address. In the case of Bitcoin, the address is a combination of 34 alphanumeric characters and numbers starting with 1. Due to the difficulty of this method, there are many services in which a server having an entire node does not lower the entire node as a web wallet service.

In this way, the existing virtual electronic money is a structure that must apply blockchain technology that must solve cryptography (random numbers) in real time in order to prove reality-free currency as a real thing. Those who have to run computers or ASIC equipment 365 days a year consume significant amounts of electricity.

In addition, the blockchain was formed to connect the above devices on the network probabilistically, which caused technical problems such as long transaction time, and even because of the virtual nature, electronic money commerce technology itself is illegal. There was a limit such as being.

The technical problem of the present invention is based on 'gold', which is recognized as a commodity by the world, and is a technology concept for converting and issuing a realized gold coin into electronic money. There is no problem of electricity consumption and prolonged transaction time, and technically overcomes the intangible specificity issue of virtual which threatened fundamentally the technology of electronic money.

The present invention is an electronic banking service combining traditional forging manufacturing, chemical / mechanical engineering and information and communication technology. A unique identification pattern, which is a code, is inserted into a gold coin weighing 375g (one-dollar) made of 100% pure gold, and this unique identification pattern becomes a medium for connecting analog to digital.The actual gold coin is converted into electronic money (DON unit). Once issued, the issued electronic money can be used for commerce (remittance of electronic money, payment / purchase of goods, etc.) regardless of nationality.

To this end, the electronic money issuing system through gold coin recognition is a gold coin patterned with a unique identification pattern (hereinafter referred to as 'gold coin'), wired and wireless communication network 100, general purpose terminal 200, electronic money management server 300 It may include.

A gold coin is a coin made of gold having a unique identification pattern formed on its surface, and is a gold coin weighing 375g (one don) based on 100% pure gold. On the surface of the gold coins, invisible unique identification patterns are formed that are invisible to the human, thereby making the value of the gold coins themselves identifiable. According to each technique (chemical / machining), the pattern shape of the unique identification pattern is different (difference in the amount of processing information), and the pattern shape should be formed so as not to overlap.

The unique identification pattern is formed through at least one of chemical techniques and machining methods.

Formation of the unique identification pattern on the surface of the gold coin by chemical technique is to spray the fluorescent ink on the surface of the gold coin to form a unique identification pattern of the unique ink pattern pattern.

Formation of the unique identification pattern on the surface of the gold coin by the machining process, by processing the engraving on the surface of the gold coin to form a unique identification pattern of the unique intaglio pattern. The micro size of this intaglio is based on the minimum micro size.

The unique identification pattern formation technique can be selected by one method, but two techniques can be processed in parallel to improve the accuracy and security.

For example, in forming the ink pattern and the intaglio pattern on the surface of the gold coin, as shown in Figs. 2 (a) and 2 (b), any of the ink pattern and the intaglio pattern on the surface of the gold coin One can be formed.

Alternatively, as shown in FIGS. 2 (c) and 2 (d), both an ink pattern pattern and an intaglio pattern may be formed on the surface of the gold coin, and different surfaces of the gold coin are shown in FIG. 2 (c). The ink pattern and the intaglio pattern may be formed separately, or both the ink pattern and the intaglio pattern may be formed on the same surface of the gold coin as shown in FIG.

In this case, when both the ink pattern pattern and the intaglio pattern are formed on the same surface of the gold coin, the intaglio pattern is formed between the ink pattern patterns, and the number of the intaglio pattern patterns positioned between the ink pattern patterns for gold coins having a high market value Can be formed to be large.

Gold coins with a higher market value are formed by combining ink pattern patterns and intaglio patterns on one and the same surface for security, and increasing the number of intaglio patterns located between the ink pattern patterns.

The wired / wireless communication network 100 is a communication network supporting wired communication or wireless communication between the general purpose terminal 200 and the electronic money management server 300. When the wired / wireless communication network 100 is implemented as a wireless communication network, a wireless mobile communication network including a base transceiver station (BTS), a mobile switching center (MSC), and a home location register (HLR) is provided. Data communication can be used. In addition, when the wired / wireless communication network 100 is implemented as a wired communication network, it may be implemented as a network communication network, and data communication may be performed according to an Internet protocol such as Transmission Control Protocol / Internet Protocol (TCP / IP).

The general-purpose terminal 200 is a device that has a camera and photographs the surface of the gold coin to read a unique identification pattern formed on the surface of the gold coin. Although the drawing shows a smartphone, not only the smartphone but also a desktop PC and a tablet are shown. The PC may be a tablet PC, a slate PC, a notebook computer, a personal digital assistant (PDA), a portable multimedia player (PMP), or the like. Of course, this foot

The terminal to which the name can be applied is not limited to the above-described type, and may include all terminals capable of communicating with an external device.

The electronic money management server 300 has the same configuration as a conventional web server in hardware, and is implemented through various types of languages such as C, C ++, Java, Visual Basic, Visual C, etc. in software. Contains program modules that function. In addition, the server hardware may be implemented by using various web server programs provided according to operating systems such as DOS, Windows, Linux, Unix, and Mac OS. Can be.

The electronic money management server 300 reads the unique identification pattern received from the general-purpose terminal 200, and determines whether a registration string matching the read unique identification pattern is registered in the database. When the registration string matching the unique identification pattern is registered in the database, a unique electronic money address is generated and assigned to the unique identification pattern to be read, and the generated electronic money address is provided to the general-purpose terminal 200. .

Thereafter, when the gold coin read through the general purpose terminal 200 is actually received in the electronic money management operation financial company, the electronic money corresponding to the market value of the gold coin received is issued to the electronic money address assigned to the gold coin.

For reference, in the database in which the registration string matching the unique identification pattern is registered, a unique registration string is registered for each unique identification pattern as shown in FIG. 3. According to each technique (chemical / machining), the pattern shape of the unique identification pattern is different (difference in the amount of processing information), and the pattern shape should not overlap, and such registered strings are unique, for example, 30-digit alphanumeric combinations. Must be a string The database is recorded in a storage medium, which includes an SSD drive, a solid state drive, a flash memory, a compact flash card, a secure digital card, and a smart card. ), A MMC card (Multi-Media Card) or a memory stick (Memory Stick), such as a module capable of input and output may be provided inside the device, or may be provided in a separate device.

4 is a flowchart illustrating a method of issuing electronic money through gold coin recognition according to an embodiment of the present invention, FIG. 5 is a detailed flowchart of reading a unique identification pattern according to an embodiment of the present invention, and FIG. According to an embodiment, an electronic money address is generated and stored in a DB. FIG. 7 is an exemplary configuration of a field recorded in an electronic money address according to an embodiment of the present invention.

In the method of issuing electronic money through gold coin recognition according to the present invention, as shown in FIG. 4, the general terminal 200 photographs a gold coin processed with a unique identification pattern on its surface to read a unique identification pattern formed on the surface of the gold coin. When the unique identification pattern is read (S410) and the unique identification pattern is read from the surface of the gold coin, the universal terminal 200 transmits the unique identification pattern to be read to the electronic money management server 300. The transmission process (S420) and the electronic money management server 300 reads the received unique identification pattern, the registration determination process for determining whether the registration string matching the read unique identification pattern is registered in the database (S430) ), And the electronic money management server 300, if the registered string matching the unique identification pattern is registered in the database, it generates a unique electronic money address and assigns it to the unique identification pattern to be read. The electronic money address providing process (S440) of storing and storing the generated and generated electronic money address to the general purpose terminal 200, and when the gold coin read through the general purpose terminal 200 is actually received, the electronic money management server ( 300 may include an electronic money issuing process (S450) for issuing an electronic money corresponding to the market value of the received gold coin to the electronic money address assigned to the gold coin. This will be described below.

The unique identification pattern reading process (S410) is a process in which the general-purpose terminal 200 reads the unique identification pattern formed on the surface of the gold coin by photographing the gold coin processed with the unique identification pattern on the surface.

An invisible unique identification pattern is formed on the surface of the gold coin, and it is possible to identify the value of the gold coin itself through the unique identification pattern. The pattern shape of the unique identification pattern differs according to each technique (chemical / machining) (difference in the amount of processing information), and the pattern shape is formed so as not to overlap.

For example, in forming the ink pattern and the intaglio pattern on the surface of the gold coin, as shown in Figs. 2 (a) and 2 (b), any of the ink pattern and the intaglio pattern on the surface of the gold coin One can be formed. Alternatively, as shown in FIGS. 2 (c) and 2 (d), both an ink pattern pattern and an intaglio pattern may be formed on the surface of the gold coin, and different surfaces of the gold coin are shown in FIG. 2 (c). The ink pattern and the intaglio pattern may be formed separately, or both the ink pattern and the intaglio pattern may be formed on the same surface of the gold coin as shown in FIG.

In this case, when both the ink pattern pattern and the intaglio pattern are formed on the same surface of the gold coin, the intaglio pattern is formed between the ink pattern patterns, and the larger the gold value of the gold coin, the size of the intaglio pattern pattern positioned between the ink pattern patterns It can be formed to be smaller or the number is larger. Gold coins with high market value are formed by combining ink pattern patterns and intaglio patterns on the same surface for security, and reducing the size or increasing the number of intaglio patterns located between the ink pattern patterns. .

Since the unique identification pattern is formed of an ink pattern pattern and / or an intaglio pattern pattern as described above, when the unique identification pattern is formed of an ink pattern pattern, when the unique identification pattern is formed of an intaglio pattern pattern, the reading methods are different.

For this purpose, the process of reading the unique identification pattern (S410) will be described with reference to FIG. 5. If it is determined that the shape of the gold coin being photographed and read (S411) is circular (S412), the process of reading the unique identification pattern is terminated. Have a process. If it is determined whether the reflector input to the image information photographed through the general-purpose terminal 200 is a round circle / rectangle (S412) or not, it is immediately excluded from recognition.

If the gold coin read is in a circular shape consistent with the server database information, it is determined whether the unique identification pattern formed on the surface of the gold coin is formed by a chemical technique, and when the chemical technique is determined, the ink pattern pattern formed on the surface of the gold coin is uniquely identified. It has a process of reading as a pattern.

Here, it is determined whether the unique identification pattern formed on the surface of the gold coin is formed by a chemical technique. The method is performed by chemical technique by irradiating special light on the surface of the gold coin (S413) to determine whether or not ink reflection light exists (S414). In operation S415, the ink pattern is extracted as the unique identification pattern when the ink reflection light exists.

In the case of non-chemical technique, it is determined whether the unique identification pattern formed on the surface of the gold coin is formed by the machining method, and when it is determined by the machining method, the intaglio pattern formed on the surface of the gold coin is read as the unique identification pattern.

Here, determining whether the unique identification pattern formed on the surface of the gold coin is formed by the machining method is to enlarge the recognition of the surface of the gold coin to be photographed (S416) to determine whether there are micropores having a predetermined size or less micro diameter (S417). Determine whether it is formed by machining.

When it is judged by the machining method, reading the intaglio pattern formed on the surface of the gold coin as the unique identification pattern is performed by first magnifying the surface of the gold coin at a first magnification (for example, 2 times) (S416), where micropores are present. If it is determined by the machining method (S417), the surface of the gold coin is magnified at a second magnification (for example, 5 times) higher than the first magnification (S418) to extract the intaglio pattern as a unique identification pattern (S419). can do.

The unique identification pattern transmission process (S420) is a process in which the universal terminal 200 transmits the read unique identification pattern to the electronic money management server 300 when the unique identification pattern is read from the photographed gold coin surface.

The registration determination process (S430) is a process in which the electronic money management server 300 reads the received unique identification pattern and determines whether a registration string matching the read unique identification pattern is registered in the database. If the registration string does not exist in the database, it is treated as unauthorized and illegal gold coins.

In the process of providing an electronic money address (S440), when a registration string matching a unique identification pattern is registered in a database, a unique electronic money address is generated and assigned to a unique identification pattern to be read, and the generated electronic money address is generated. It provides to the general-purpose terminal 200.

For example, if there is a first registration string whose unique identification pattern to be read is matched with the first pattern as the first pattern, as shown in FIG. 6, a unique electronic money address is generated to generate the electronic money in the first pattern. It generates and stores as an address, and informs the universal terminal 200 of the recognition success and the generated electronic money address.

This electronic money address becomes, for example, a unique memory address in a 25-digit redundant storage. Therefore, unique information can be recorded for each memory address serving as an electronic money address.

In the electronic money issuing process (S450), when the gold coin read through the general-purpose terminal 200 is actually received, the electronic money management server 300 allocates the electronic money corresponding to the market value of the gold coin to the gold coin. It is a process of issuing to an electronic money address. In other words, when a gold coin read and registered by the issuer is physically deposited, the electronic money management server 300 reads the gold coin to an already generated address (or the electronic money management server 300 recognizes and generates it in the gold coin deposit step). Issue electronic money GLD.

To this end, the electronic money issuing process (S450), the electronic money management server 300, the process of reading the unique identification pattern formed on the surface of the gold coins received (S451), and the registration string matching the read unique identification pattern Extracting the assigned electronic money address, and recording the electronic money corresponding to the market value of the received gold coins in the extracted electronic money address (S452). For example, if the amount of gold coins received is 1 money, the electronic money address corresponding to the market value of 1 money is recorded in the electronic money address. If the amount of gold money is 2 money, the electronic money is extracted from the electronic money corresponding to the market value of 2 money. It records in the money address, and if the received gold coin is 3 money, the electronic money corresponding to the market value of 3 money is extracted in the electronic money address.

As shown in FIG. 7, the electronic money address may include an electronic money field in which electronic money is recorded, and an owner field in which a gold coin owner is recorded.

Therefore, the electronic money storage process records the electronic money corresponding to the market value of the gold coins put in the electronic money field, and records the information of the owner wearing the gold coins in the owner field.

In addition, when a transfer of issued electronic money occurs due to purchase, payment, remittance, etc., the last owner information received is updated and stored in the owner field. Therefore, not only electronic money but also owner information of electronic money is recorded in the electronic money address, thereby preventing illegal use of electronic money by third parties other than the owner.

The embodiments in the above description of the present invention are presented by selecting the most preferred examples to help those skilled in the art from the various possible examples, and the technical spirit of the present invention is not necessarily limited or limited only by the embodiments. However, various changes, modifications, and other equivalent embodiments may be made without departing from the technical spirit of the present invention.
