     Description of Related Art 
     Although cryptocurrency using block chain has been developed, it is difficult to commercialize it due to the limitations of technology, which makes it difficult to quickly process large-scale transactions. Because the powers that create and operate blocks are specified, it has a structure that makes it difficult for ordinary people to participate in system operation, and there is a problem that it is used as a means of payment for various illegal or criminal acts based on anonymity. 
     Recently, CBDC (Central Bank Digital Currency) has been the subject of research around the world, and interest is high enough that China has already announced a specific issuance plan. However, this is nothing more than the online conversion of a specific country&#39;s monetary system. Since CBDC itself is based on the monetary system of a specific country, there is a limitation in that it does not function as a universal currency. In addition, as the central axis has recently shifted to online transactions rather than offline transactions, the use of offline currency is decreasing and online account transfer transactions are increasing, the use of digital currency in a specific country has no special meaning other than omitting the printing or production of currency in a specific country. 
     In modern times, it is customary to exchange the currency for each country into the currency of a specific country and settle the payment in the domestic currency circulation as well as in the commerce between countries. However, there is a problem in that a process of exchanging money by applying the exchange rate at each point in time is required, and in this process, various transaction fees are generated and it takes a certain time to complete the settlement, so there is a problem in that intermediate costs or fees are excessively generated. 
     Therefore, there is a need for digital currency that can be used in common all over the world beyond a specific country. In this regard, the invention of the international electronic money system in Korean Patent Publication No. 10-2006-0099957 (published date: Sep. 20, 2006) is disclosed. 
     The disclosed invention is an international electronic money system including an international settlement server, an issuing country settlement server, and a user country settlement server connected to each other through a predetermined communication network, wherein the issuing country settlement server issues an electronic money card to the user, and charges a predetermined amount of electronic money to the electronic money card according to the exchange rate information scheduled for the exchange rate, and pays the first settlement amount corresponding to the settlement request information received from the international settlement server to the international settlement server, wherein the user country settlement server transmits the electronic money settlement details information transferred from the electronic money card issued by the issuing country settlement server to the user country settlement server according to the usage exchange rate information for the user country to the international settlement server, and receives the second settlement amount corresponding to the settlement details information from the international settlement server, and wherein the international settlement server transmits the scheduled exchange rate information for each country and the exchange rate information used for each country to the settlement server of each country, and uses the settlement details information received from the settlement server of each country to obtain the first settlement amount and the second settlement amount is calculated, the settlement request information requesting payment of the first settlement amount is transmitted to the settlement server of each country, and the second settlement amount is paid to the settlement server of each country. 
     In addition, the invention of a method for intermediation of foreign exchange dealings through the medium of digital assets based on block-chain technology including crypto currency in Korean Patent Publication No. 10-2019-0091211 (published on Aug. 5, 2019) is disclosed. 
     The disclosed invention relates to a method of currency exchange and foreign exchange transaction using a blockchain-based digital asset including cryptocurrency as a medium. The exchange method of the disclosed invention uses an environment in which different currencies are traded within one exchange, excluding the method of transferring blockchain-based digital assets between exchanges, which has a long waiting time, an environment in which multiple exchanges transacting with different currencies share the digital assets through contracts, etc., or an environment that shares transaction information between exchanges even if the digital assets are not directly shared to create a foreign exchange market using the digital asset as a medium in a blockchain-based digital asset exchange, and the consumer directly applies the market&#39;s buy-sell spread to exchange easily and quickly without economic loss do. 
     Since the disclosed invention of international electronic money system is a transfer from offline to online where the conventional currency of a specific country is converted into an exchange rate related to the currency of each country, there is a limit to improving the reliability of electronic money and activating the use between countries. 
     In addition, the disclosed invention related to the exchange of cryptocurrency and foreign exchange, which converts the block-chain-based cryptocurrency into a heterogeneous currency, has a problem in that there is a limitation in its effectiveness in activating the reliability of electronic money and the use of cross-border use. 
     Therefore, there is a need for an invention, which can convert an existing currency into an international digital currency that can be used between countries without paying a fee, and in converting the currency into international digital currency, secures the security of financial transactions by performing the applicant&#39;s identity authentication through identity authentication of multiple applicants, determining whether to approve the conversion of the applicant by a predetermined number of non-related persons from a predetermined number of other countries not related to the applicant, and improving the reliability of international digital currency and activating the use of international digital currency.

       FIG.  5    is a schematic diagram illustrating an embodiment of an IDC management system, which is a specification of an operation system of the International digital currency of the present invention. 
     As illustrated in  FIG.  5   , the IDC management system  1400  of the present invention includes an IDC program management unit  1411  which manages users and user terminal information of each country using the IDC system, and upgrades and uses web programs, application programs and cloud computer programs used in the IDC system, an IDC publicity information management unit  1412  which manages guide information and publicity information provided to the IDC user interface of the user terminal of the user groups  2100 ,  2200 ,  2300  of each country, an IDC issuance information management unit  1413  which manages the issuance information of international digital currency, including conversion information of the key currency into international digital currency and additional issuance of profit-type international digital currency, an IDC money supply information management unit  1414  which adjusts the money supply of the entire international digital currency in relation to the issuance, circulation and conversion of international digital currency; and an IDC revenue information management unit  1415  which sets and stores the profit information provided to the conversion requester, non-related persons in each country participating in the approval of the conversion application, and the IDC system, when users in each country convert their key currency into international digital currency. 
     With reference to the embodiment of the present invention of  FIGS.  1  to  5    described above, a more detailed description will be given in relation to the operation of the international digital currency system of the present invention. 
     Users of each country who want to use the international digital currency system of the present invention access the IDC account creation system  1100  through a user terminal, and apply for membership through identity authentication. 
     The IDC account creation system  1100 , which has received the membership application, performs identity authentication as to whether the user is correct based on the information collected from the SNS system with related persons such as the applicant&#39;s acquaintances based on the applicant information, and performs user authentication of the applicant. 
     A user whose user authentication has been completed applies to open an international digital currency (IDC) dedicated account for each country for foreign exchange and use of international digital currency to the IDC account generation system  1100  in order to use the international digital currency system. The IDC account generation system  1100 , which received the application for an international digital currency (IDC) dedicated account, generates and stores an international digital currency (IDC) dedicated account for each country in connection with user information, and transmits the international digital currency (IDC) dedicated account information opened to the user terminal that has applied for it. 
     In the state that the International digital currency (IDC) dedicated account receives the approval of linkage with the existing financial account at the domestic financial institution, or is automatically linked, the user terminal accesses the IDC conversion management system  1300  and applies for conversion of a predetermined amount of financial information stored in an international digital currency (IDC) dedicated account into international digital currency. The IDC conversion management system  1300 , if the currency for which the request for conversion to the international digital currency is not a set key currency, converts it into a key currency using the foreign exchange management system  1200 , and based on the exchanged key currency conversion to international digital currency. The IDC conversion management system  1300  selects a set number of countries from among the countries linked to the IDC system, for validation of the conversion to international digital currency, and extracts participant information as non-related persons in the selected country. Here, preferably, information of a set number of participants among users who opened an international digital currency (IDC) dedicated account in the IDC system is extracted. 
     By providing the international digital currency (IDC) dedicated account information within the limited information of the applicant who applied for the conversion to the international digital currency to the extracted participants from each country, check whether the conversion amount of the conversion applicant is correct, and if it is confirmed that there is no problem in the conversion details, the applicant&#39;s conversion to international digital currency may be approved. 
     At this time, the method of verifying the validity of the conversion by the non-related person participant is to be calculated using a calculation program in the terminal of the non-related participant, a calculation-related utility provided from the cloud computing system  3000 , or a calculation program built into the IDC systems. In addition, the exchange rate information can be checked and verified by accessing the internet network and inquiring and calculating the exchange rate at the time of conversion request or verification in real time. 
     In this case, it is desirable to exclude the country to which the applicant for international digital currency conversion belongs in the selection of participants. 
     However, in the early stage when the use of this system has not been established internationally, it may be a practical application of this system to include some participants from the country to which the conversion applicant belongs and to gradually reduce the proportion of participants from the country to which the conversion requester belongs. 
     The present invention selects n or more countries among countries excluding the applicant&#39;s country, selects k or more of the total number of international digital currency (IDC) dedicated account openers in the selected n countries, and makes a decision on whether to approve the applicant&#39;s application for conversion. 
     Here, the numerical value of n of countries participating in approval is set by the IDC system operator, for example, 10 countries, and the number of participants in approval k is set to 100. Preferably, the artificial intelligence computer may analyze the data value to calculate and apply a numerical value optimized for manipulation prevention. 
     The IDC system and artificial intelligence computer randomly select the nationality of approved participants and the number of people per country, but it can be set so that the number of participants is not excessively assigned to a specific country. 
     The IDC management system  1400  may provide profits to a conversion applicant f to international digital currency and a non-related person participating in the approval of the conversion application. 
     The amount of international digital currency set in the standard conversion rate may be additionally paid to the applicant who applied for conversion of the key currency to the international digital currency. For example, if the key currency is USD, if you additionally pay  1  international digital currency (hereinafter referred to as “DC”) when applying for USD  100  conversion (assuming that the conversion rate based on international digital currency is 1:1), It can be configured to be converted to DC 101 in the international digital currency (IDC) dedicated account of the conversion applicant and to reduce 100 dollars as soon as the international digital currency is deposited. 
     Here, the ‘conversion rate’ when converting the key currency into international digital currency is explained on the premise that it is set to 1:1 for convenience. However, other internationally agreed rates may be applied for the purpose of adjusting the issuance volume or resetting or adjusting the exchange value in consideration of the social and economic functions of money. 
     In addition, for the distribution of profits to non-related persons in each country who approved and participated in the application for international digital currency conversion, the amount of the specified international digital currency is additionally calculated from the converted international digital currency, and the amount is equally distributed to the approved participants. For example, when DC 100 is converted, DC 1 is additionally issued and if there are 100 approved participants, DC 0.01 can be credited to the International digital currency (IDC) dedicated account of approved participants, etc. 
     The amount of additional international digital currency paid to the applicants for the conversion to the international digital currency and the participants for approval is, if you want to link the value of goods to the amount of profit provided, post advertisements, etc. It may be configured to be procured by making payment. In this case, the value of the goods is tied to the amount of profit provided. 
     In this case, it can be considered that international digital currency has been additionally paid or issued as much as the value (fees, etc.) created by the advertisement posting. 
     When it is necessary to control the amount of international digital currency, it can be performed by increasing or decreasing the evaluation amount by setting the evaluation balance of the entire international digital currency (IDC) dedicated account as the reference point at a specific time. 
     When an increase or decrease in the amount of money is performed, it can be adjusted to increase or decrease the amount of international digital currency in the entire International digital currency (IDC) dedicated account. 
     The profit rate provided to the applicant for the conversion to the international digital currency and the approval participant, the adjustment rate when adjusting the money supply of the international digital currency, and the conversion rate of the key currency to the international digital currency may be used to calculate using the numerical determination system (Patent No. 10-1998825) of the present applicant. 
       FIG.  6    is a flowchart illustrating an operating method of the international digital currency according to an embodiment of the present invention.
