The transaction system of the digital virtual currency having the block chain between the parties, which is a background technology for applying this patent, has also been patented with Patent Registration Nos. 10-1673073 and 10-1628007.

Bitcoin (BTC) system was developed in 2009 by an individual or group of programmers who use the nickname Nakamoto Satoshi. It is basically a pear-to-pear (P2P) Based distributed database. In short, it means that individual computers or servers with bit coin programs installed collectively create a whole bit coin system.

In this system, what we call bit coin is created through the act of Mining (which is originally called Data Mining, which means "information mining" in our country, but "mining" in Korea) You can store and trade in your wallet. These bit coins are currently being mined and circulated by about 13.8 million, and 21 million are scheduled to be mined sequentially in 21 million.

The most important word in the description of bit coin is Mining.

Mining is usually a way to get a new bit coin. The process of providing a bit coin to a computer that finds it first by competing with a computer (terminal) constituting a bit coin network to find an operation value satisfying a specific condition is called mining. However, this mining is not only a method of acquiring a simple bit coin but also a role of authenticating a bit coin transaction.

Worldwide companies that receive payments by bit coin now include DELL (computer), MicroSoft (software), Expedia (the world's largest online travel agency), and Braintree, a subsidiary of PayPal (billing) It is. The approximate franchise status can be found at http://coinmap.org.

The following is the structure of the Crypto-Currency.

Crypto-currencies represented by bit coins have a common type of transaction book called a block chain.

As a general overview, a typical user downloads a wallet program of encrypted currency to his computer. Then install it on your own computer. Then, the program starts executing the task of synchronizing itself with the block chain recorded on the network while it is being executed. Because the data is tens of gigabytes, it usually takes 3-7 days. After the synchronization is complete, you can create your own address (the concept of an account at the bank) in your wallet and send or receive a bit coin through that address. (In the case of bit coin, the address is 34 alphanumeric Case) and numbers (ex, 1MowqQrQJL5AeaDMpX35B6EiJ4qnXPJnFp).

Here, all of the Crypto-Currency that is run in the block-chain system including the bit coin is a pair of keys in the form of 'private key-public key (address)' by the user terminal. The public key corresponds to the bank account number and the private key corresponds to the password, which is a pair that fits only with one another.

In the case of the bit coin QT program (user's personal wallet program), the private key is encrypted using the user's password and stored in the member computer.

In the case of Web Coin Exchange, a private key is encrypted and stored on the server using user password or SALT of the server.

Anyway, the existing approach is to store the private key on the server or store it on the member computer.

In other words, the Exchange security related internal person who knows how to encrypt is likely to decrypt the encrypted private key stored in the server and secretly use it.

When a member views his or her account through an exchange server, the balance stored in the server database (DB) is displayed. The actual balance existing at the address is meaningless to the member. The actual transmission of bit coin requires six checks, which takes about an hour, which makes it impossible to trade in a short period of time.

1 to 4, the digital virtual currency trading system having a block chain between parties of the present invention includes a plurality of block chain holding servers 100, a block chain-based digital virtual currency trading guidance server 200, A donor terminal 300 and a water purifier terminal 400.

The calling terminal 3100 is used, for example, by a user to call the phone banking server 160 and input personal information such as a user's account number, password, and resident registration number as a DTMF signal.

In order to prevent the input DTMF signal of the personal information input by the user through the calling terminal 100 from the risk of hacking, the conversion device 3110 converts the input DTMF signal into conversion logic based on a predetermined authentication number provided from the reception device 3210 And converts the inputted DTMF signal.

The source-side switching center 3120 transmits the converted DTMF signal input from the conversion apparatus 3110 to the destination switching center 3200 via the communication network.

The called party switching center 3200 receives information transmitted from the calling party switching center 3120 via the communication network. It is formed in the personal finance transaction relay server.

The receiving device 3210 restores the converted DTMF signal received from the destination switching center 3200 into the DTMF signal of the original personal information.

The phone banking server 3300 finally receives the DTMF signal restored from the reception device 3210 and performs a phone banking service of the user.

The authentication number may be fixedly used in the receiving apparatus 3210 and used irregularly.

In the case of the authentication number fixed to the receiving device 3210, the receiving device 3210 searches the database based on the calling number of the customer and uses the same.

The authentication number is received from the receiving apparatus 150 during operation and stored therein, and the converter 401 converts the number using a combination of the inputted number and the authentication number.

FIG. 8B is a diagram illustrating the function of the restorer 403 of the number restoring unit 315. The number restored by the converter 401 is converted into an original number using a predetermined authentication number.

The receiving apparatus 3210 may transmit the authentication number every time the DTMF signal is required, or may be used as the authentication number until the call is terminated after the first transmission.

The conversion apparatus 3100 converts the received authentication number from the receiving apparatus 3210 using only the most recently received authentication number.

The following is an example in which the original number is converted into another number by the numeric conversion unit 217 using a predetermined authentication number.

Assume that the input digit is '3456' and the authentication number is '11'.

The converted digit '4' is added by adding the first digit '3' of the input digit and the first digit of the authentication number '1'.

To create a number to be added for conversion, the decimal place '1' and the place of day '1' of the authentication number are added to the converted number '4' to make a number '6'.

After making the data by the conversion device using the logic, the data is transmitted by the receiving device, and the authentication signal is transmitted to the phone banking server.

As a result, the technical content applied to the present invention applies to the fingerprint and / or fingerprint authentication means, and the step of processing authentication of the fingerprint or fingerprint applied to the fingerprint and / Transmitting the personal information to the receiver side exchange of the personal finance relaying transaction server using the DTMF signal; Returning a predetermined authentication number from the receiver side exchange of the personal finance relay transaction server; Converting an arrangement of the DTMF signals and transmitting the DTMF signals to a receiving device according to conversion logic based on a predetermined authentication number to which the fingerprint or finger vein information is returned; Reconstructing the converted DTMF signal into an array of DTMF signals originated by a user according to conversion logic based on an authentication number used for DTMF signal conversion; If the transmitted fingerprint or fingerprint information coincides with the fingerprint or fingerprint information registered in the personal financial transaction relay server, the personal banking transaction server accesses the online banking system or the electronic commerce system without authentication through the personal financial transaction relay server And a step of relaying the financial transaction. The method of the present invention is a transaction method of a digital virtual currency having a security and an anti-hacking function.

FIG. 10 is a block diagram showing an iris recognition apparatus using a camera for short-distance iris photographing according to an embodiment of the present invention. FIG. 11 is a block diagram of a near- 12 is a flowchart illustrating an iris recognition method using a camera for photographing according to an embodiment of the present invention. FIG. 12 illustrates a method for normalizing an iris recognition method using binary camera FIG.

10, the iris recognition device using the camera for short range iris photography of a smartphone according to an embodiment of the present invention includes a camera 1 for iris photography, a key input unit 2, a storage unit 4, a control unit 3 An output unit 5 and a display lamp 300. [

As shown in Korean Patent Laid-Open Publication No. 10-214-0133762, the iris camera 1 has a prism 200 having an inclined surface on an upper portion of a guide of the illumination IR LED 20, Thereby improving the iris recognition and preventing the static electricity from being transmitted to the internal device through the illumination IR LED 20, so that it can be formed small.

The key input unit 2 selects whether to register the iris or recognize the iris through the iris recognition apparatus. The storage unit 4 stores a program for registration and recognition of the iris and iris data for the recognized iris image at the time of registration.

The output unit 5 outputs the result of iris recognition by the control unit 3, and provides various services according to the iris recognition result in a peripheral device (not shown). The control unit 3 operates the iris photography camera 1 according to the selection of the key input unit 2, photographs the iris according to the brightness of illumination, determines whether the iris is a living person's iris through a change in pupil size, The iris data for the iris image is stored and registered or the iris data and the iris recognition for the iris image stored in the storage unit 4 are performed.

The iris information fuses with other signals and is utilized as an anti-hacking means.

The display lamp 300 is turned on so that the user can recognize that the iris image is being recognized by operating the iris photographing camera 1 in the control unit 3. [ At this time, the display lamp 300 may display the progress of the display through various colors.

11, in the iris recognition method using a camera for a short distance iris photographing of a smartphone according to an embodiment of the present invention, when the iris recognition is selected in the key input unit 2 (S10) The iris 1 is operated to photograph the iris according to the brightness of the illumination (S22).

At this time, the operation state of the camera 1 for iris photography is displayed through the display lamp 300 to recognize that the user is operating. Even if the human iris is the same person, the size of the pupil changes according to the brightness of illumination as shown in the figure, and the iris pattern also changes.

In the prior art, the iris image is acquired while the iris is photographed while varying the brightness of the illumination while maintaining the characteristic that changes according to the individual characteristics. After the iris is imaged according to the brightness of the illumination, it is determined whether there is a change in the pupil size (S24).

At this time, if there is no change in pupil size, it can not be judged to be a living person. When an eye of a living person is photographed, as the size of the pupil changes, one iris image is acquired for iris recognition among the iris images thus changed (S26).

As shown in FIG. 12, the obtained iris image is normalized into binary data for each pixel of the imaged iris image to generate iris data (S28).

That is, the iris data can be reduced in the amount of data by normalizing it with binary data indicating that there is no pattern irrespective of the increase of the iris pattern. Therefore, the processing speed can be improved and the recognition speed can be improved. Also, the processing speed can be improved through the low-specification system, and the miniaturization and portability can be increased, and the influence of night and day and illumination can be minimized.

Then, the comparison result is outputted through the output unit 5 so that various services can be provided through a peripheral device (not shown) through the iris recognition result (S32).

On the other hand, when the iris registration is selected in the key input unit 2 (S10), the control unit 3 operates the iris photography camera 1 to photograph the iris according to the brightness of the illumination (S12). At this time, the operation state of the camera 1 for iris photography is displayed through the display lamp 300 to recognize that the user is operating.

Even if the human iris is the same person, the size of the pupil changes according to the brightness of the illumination, and the iris pattern also changes. In the prior art, the iris image is acquired while the iris is photographed while varying the brightness of the illumination while maintaining the characteristic that changes according to the individual characteristics.

After the iris is imaged according to the brightness of the illumination, it is determined whether the size of the pupil is changed (S14). At this time, if there is no change in pupil size, it can not be judged to be a living person.

When the eye of a living person is photographed, as the size of the pupil changes, a plurality of iris images are acquired for iris registration in the thus changing iris image (S16). As shown in FIG. 12, iris data for a plurality of acquired iris images are normalized with binary data for each pixel of the imaged iris image to generate iris data for a plurality of iris images (S18). That is, the iris data can be reduced in the amount of data by normalizing it with binary data indicating that there is no pattern irrespective of the increase of the iris pattern.

Therefore, it is made up of binary data that is determined by dividing each pixel, and these data and the conversion device are fused to generate a new signal.

Registration is performed by storing the iris data for the plurality of iris images thus generated in the storage unit 4 (S20). As described above, according to the iris recognition method using the camera for the near iris photography of the smartphone according to the present invention, the iris image taken through the camera for the near iris photography of the smart phone is processed into the binary data according to the iris pattern of each pixel, It is possible to reduce the recognition rate through the change of iris pattern and path, and it can be processed through the system of low specification, so that miniaturization and portability can be increased, The recognition rate can be increased irrespective of whether the pattern is intact or not.
