Abstract

Recent copy-protection schemes for digital video copy-protection rely on a pixel-watermark together with the presence of a "ticket" to implement the "copy-once" state of content. This ticket is designed to entitle the owner of a disk/tape to making onecopy of digitalcontent. We disclose a method to pass along this ticket with the video signal after content has been converted to the analog domain. This form of the ticket is called the analog ticket. The analog signal may be recorded on a legacy device that does not comply with the copy-protection scheme (e.g. ordinary VCRs). The analog ticket is designed such that it is automatically removed in these legacy devices. Next generation copies by compliant devices are made impossible. Three possible ways of embedding the ticket signal into the analog video signal are proposed.

Description

A foreign-exchange trading system and method based on a network

The present invention relates to a forex trading system and method based on a network.

More specifically, the main server is connected to a plurality of client PCs, bank servers, and gift companies through a network network to recommend the most favorable product to users among various foreign currency products (e.g., spot exchanges, futures exchanges, and futures) and at the same time, users and banks / gifts. The present invention relates to a forex trading system and a method based on a network that allows forex trading between companies.

Generally, the exchange rate of one country's currency and another country's currency at a certain point of time is called an exchange rate. Foreign currency in the foreign exchange market is treated as a kind of commodity, and a trading price called an exchange rate is formed. The exchange rate is determined by supply and demand.

In general, a futures exchange transaction refers to a foreign exchange transaction that concludes a trading transaction of a specific currency with a predetermined date as a settlement date, and then exchanges the contract currency at a predetermined exchange rate and setstles the settlement at the settlement date.

A futures transaction is a transaction in which a dollar is bought or sold at a price (present price) at the time of the conclusion of a future transaction, and a transaction is received in which a real takeover occurs at the final settlement date.

The main purpose of these futures exchanges and futures trading is to prevent risks caused by exchange rate fluctuations. In order to prevent future changes in the purchase or sale of foreign currency, the value of the futures exchanges or futures will be concluded.

As a result, in case of futures exchange transactions, the amount of future receipt / payment is determined in advance so that stable fund management is possible and foreign currency gains can be raised by buying a strong anticipated currency in advance. The downside is that you have to give up the opportunity gain that can be realized if it changes.

For example, if there is a risk of an exchange rate rise in the future, the importer can benefit from buying a won / dollar forward or futures and fixing future exchange rates. You can benefit by selling futures to fix future exchange rates.

Conventionally, in order to purchase or sell foreign currency, a user can open a bank account by designating a foreign exchange bank and then buy or sell only through the designated bank.

However, the conventional futures exchange transaction as described above is inconvenient because the user visits the bank to find out the futures exchange rate and conducts a transaction, or the futures exchange rate is made through a communication means such as a telephone. There was a problem.

Next, the operation of the system according to the present invention configured as described above will be described in detail with reference to the flowcharts shown in FIGS. 2 to 4 and the screen diagrams shown in FIGS. 5 to 7.

FIG. 2 is a flowchart schematically showing a network-based forex trading method according to the present invention, FIG. 3 is a flowchart showing in detail the 40th step of FIG. 2, and FIG. 4 shows the 70th step of FIG. 5 to 7 are screen diagrams for explaining user position information, price information, recommendation position information, payment amount comparison information, and order confirmation information displayed on the screen of the client PC according to the present invention. .

First, when a user using the client PC 200 wants to receive a foreign exchange transaction service such as a spot exchange, a future exchange, or a gift online, a web browser for accessing a web page of the main server 500 opened on the Internet or the like is provided. Must be installed.

Accordingly, when the web browser installed in the client PC 200 is executed by the user in the tenth step S10, a communication connection is made to the main server 500 according to the set communication environment.

When the main server 500 and the client PC 200 are connected in communication, the main server 500 outputs a user position form to the client PC 200 in step 20.

Accordingly, in the thirtieth step (S30), the client PC 200 displays the user position form on the screen while the expected payment date, the transaction purpose, the transaction amount, User position information, such as an operating rate, a dollar borrowing rate, a won operating rate, and a won borrowing rate, is uploaded to the main server 500.

At this time, the current date information is downloaded from the main server 500 and displayed in the "transaction day" item of the user position form.

In addition, in the "expected settlement date" item, a future payment date is input by the user, and in the "transaction amount" item, a dollar amount to be bought or sold by the user in the future is input.

In addition, the “classification” item allows an individual or a legal entity to be selected by the user in order to distinguish the interest rate when operating in won or dollar.

In addition, the user is expected to predict the movement of the exchange rate to select "import, payment" or "export, deposit" through the "transaction purpose" item, that is, if there is a risk of exchange rate increase in the future, Select "import, payment" when the risk of exchange rate fall in the future, if the exporter wants to remove it, select "export, deposit".

In addition, the user is required to enter the dollar operating interest rate, dollar borrowing interest rate, won operation interest rate, won currency interest rate, where "dollar operating interest rate" means the user's holding of the dollar funds through the bank during the period from the transaction date to the expected settlement date. It is the interest rate that can be applied when operating, and the "dollar borrowing rate" is the interest rate that can be applied when the user borrows dollar funds through the bank during the period from the transaction date to the expected settlement date. The interest rate that can be applied when the user manages the won-denominated funds through the bank for the period from the transaction date to the expected settlement date, and the "won-denominated operating interest rate" refers to the won-denominated funds through the bank for the period from the transaction date to the expected settlement date. The interest rate that can be applied when borrowing.

Accordingly, the user position information such as expected payment date, transaction purpose, transaction amount, dollar operating interest rate, dollar borrowing interest rate, won operating interest rate, won borrowing interest rate and the like received from the client PC 200 in step 40 (S40). Based on the spot exchange price information, the future exchange price information received from the bank server 300, and the futures price information received from the future company server 400, the main server 500 recommends position information, futures (hwan) theoretical price information, Generates dollar purchase / sell payment amount information at the point of payment and outputs the information to the client PC 200, while the spot exchange price, the future exchange price, and the futures price information received from the bank server 300 and the future company server 400 are displayed. Output to the client PC (200).

Here, “the futures (the ring) theory price range is determined by the formula of Equation 1 (a) when the purchase price, and is determined by the formula of Equation 1 (b) when the selling price.

Here, the "payment amount" is the amount of won required to actually pay on the settlement date.

For example, when the user selects "import and payment" in the "transaction purpose" item, as shown in FIG. 5A, the main server 500 includes recommendation position information, futures (currency) price range information, and recommendation position. Cash flow information of the foreign exchange transaction according to the present, and the dollar purchase payment amount comparison information at the time of payment is presented to the user, when the user selected "export, deposit", the main server 500 as shown in Figure 5b The main server 500 presents the user with the recommended position information, the futures (exchange) theory price range information, the cash flow information of the foreign exchange transaction according to the recommended position, and the dollar purchase / sell payment amount comparison information at the time of settlement.

In addition, the 40th step (S40) includes a payment amount comparison process, first, when the main server 500 outputs the payment amount comparison form to the client PC (200) (S41), the client PC (200) ) Displays the payment amount comparison form on the screen, while the user position information input from the client PC 200 and the spot exchange price input from the bank server 300 through the payment amount comparison form screen (see FIG. 5A). Information on the amount of the exchange, when the main server 500 uses a spot exchange, a forward exchange, or a future to manage currency risk, based on the information, the future exchange price information, and the future price information input from the future company server 400. It generates and outputs to the client PC (200) (S43).

For example, when the user selects "import and payment" in the "trade purpose" item, as shown in Figure 5a, the amount of payment in the unhedged transaction is determined by the formula of Equation 2, The settlement amount is determined by the formula of Equation 3, the settlement amount at the time of the future transaction is determined by the formula of Equation 4, and the settlement amount at the time of purchase of the spot is determined by the formula of Equation 5.

By comparing the calculated payment amount, the main server 500 recommends a product that is most advantageous to the user, and outputs "cash flow" information to the client PC 200 when a transaction is made with the recommended product.

In this case, if the recommended product is a forward exchange purchase, a screen as shown in FIG. 6A is output. In the case of a future purchase, a screen as shown in FIG. 6B is output. The same screen is displayed.

In addition, when the user selects "export, deposit" in the "transaction purpose" item, as shown in Figure 5b, the payment amount in the unhedged transaction is determined by the formula of Equation 6, the payment at the forward exchange transaction The amount of money is determined by the equation of Equation 7, the amount of payment in the futures transaction is determined by the equation of Equation 8, and the amount of payment in kind is determined by the equation of Equation 9.

By comparing the calculated payment amount, the main server 500 recommends a product that is most advantageous to the user, and outputs "cash flow" information when trading with the recommended product.

In this case, when the recommended commodity is a forward exchange, a screen as shown in FIG. 6D is output. In the case of a future sell, a screen as shown in FIG. 6E is output. In the case of a spot sale, a screen as shown in FIG. 6F is displayed. Is output.

The user determines whether to order a transaction through the recommendation position information screen and the payment amount comparison information screen.
