2 is a flowchart illustrating an e-commerce process of the e-commerce system according to the present invention. 3 is a detailed flowchart illustrating a step of exchanging identification information between a plurality of terminals and a platform server according to the present invention. 2, exchanging identification information between a plurality of terminals and platform servers (S210), exchanging advertisement information between a plurality of terminals and platform servers (S220), transaction information between a plurality of terminals and platform servers and exchanging (S230) and exchanging product review information between a plurality of terminals and platform servers (S240).

2, the detailed flow of the step (S210) of exchanging identification information between a plurality of terminals and the platform server is when the first terminal 200 transmits the first identification information to the platform server 100 (S310), The platform server 100 establishes a two-way encrypted channel between the first terminal 200 and the platform server 100 using the first identification information (S320).

- 1) 범위에 있는 숫자 중의 하나인 개인키를 생성하여 공개키를 생성한다. Here, user authentication is a method of generating a private key and a public key and cross-matching them, and the identifier uses an x-coordinate value, which is one of the public keys. Specifically, it is expressed in 64-digit hexadecimal numbers with a length of 256 bits that do not overlap using a pseudo-random number generator, a known technology.

- 1) Create a public key by generating a private key that is one of the numbers in the range.

The method of generating a public key using the private key applies an elliptic curve multiplication formula, which is expressed as S=k*G, which is an expression of arithmetic on the value of S by adding G to k times, where S is A public key, k is a private key, G is a constant point, and the constant point G is a reference coordinate (x, y) for generating a public key (S), and in the present invention, NIST (US National Institute of Standards and Technology) ) applies the standard (0, 7) of secp256k1 established by That is, it is impossible to calculate k, which is the private key, by inversely calculating the value of the arithmetic public key S by division. As a result, a public key that can be shared by anyone can be used as an identifier while securing security that the private key is not leaked.

By using the elliptic curve multiplication formula, the constant point (0, 7) value is added as much as the number of the private key generated in the above-described manner, and the public key (x, y) value is arithmetic, and only the x value is used as the public key. This is because storage space is saved and, if necessary, the y value can be calculated using the elliptic curve function expression.

을 사용하여 산술했을 때 그 결과 값은 0 으로 산술되므로 써 상기 일례의 (x, y) 값의 좌표가 상술한 secp256k1 표준의 타원곡선 그래프 중의 한 점이라는 것을 검증할 수 있다.Here, as the x and y coordinates on the elliptic curve function graph according to the mod p value of 17, that is, when the maximum value of the (x, y) coordinate is 17, one x value has two symmetrical y values. That is, when x is 1, y values are 5 and 12, when 2 is 7 and 10, when 3 is 0, when 5 is 8 and 9, when x is 6, 6 and 11, when 8 is 3 and 14, 10 When 2 and 15, 12 when 1, 16, and 15 when 4 and 13, the curve value is (0, 7), which coincides with (0, 7), which is the constant of the elliptic curve multiplication formula above, and the area The (Field) value is 17, which is an elliptic curve function graph that is consistent with the mod p value of 17 of the above elliptic curve function expression. That is, the value calculated by the above elliptic curve multiplication formula for the generated private key becomes two coordinate values on the elliptic curve function graph because two y values are arithmetic on one x value. This is expressed as a decimal number, and when expressed as a hexadecimal number to represent mod p and one (x, y) coordinate as an example, p is 115792089237316195423570985008687907853269984665640564039 457584007908834671663 1050291050345802934458 of 210345839 It can be expressed as an elliptic curve function

Since the result value is arithmetic as 0 when arithmetic using , it can be verified that the coordinates of the (x, y) values in the above example are one of the points in the elliptic curve graph of the secp256k1 standard described above.

Values (x, y) for showing the generated private key value, for example "f8f8a2f43c8376ccb0871305060d7b27b0554d2cc72bccf41b 2705608452f315" arithmetic lower by substituting the elliptic curve multiplication function equation S = k * G S as described above (6e145ccef1033dea239875dd00dfb4fee6e3348b84985c 92f103444683bae07b, 83b5c38e5e2b0c8529d7fa3f64d46daa1ece2d9ac14 cab9477d042c84c32ccd0 ), which is expressed as a hexadecimal number of 130 digits and occupies a capacity of 65 bytes. In order to use this as an identifier compatible with the address of the electronic wallet for mutual transfer of cryptocurrencies, in the following four types of rules set by SEC1 (Standards for Efficient Cryptography 1)

| Prefix | Meaning | Length (bytes)

| 0x00 | Point at Infinity | One

| 0x04 | Uncompressed Point | 65

| 0x02 | Compressed Point with even Y | 33

| 0x03 | Compressed Point with odd Y | 33

By applying the 0x04 rule, 04 + X-coordinate (32 bytes/64 hex) + Y-coordinate (32 bytes/64 hex), the arithmetic (x, y) value can be displayed as 046e145ccef1033dea239875dd00dfb4fee6e3348b84985c92f103444683bae07b83bcd46d4683.

By the equation with respect to a private key 1 where along the two y values is generated for a single value of x the value of x that is save storage space by using the public key in the one 046e145ccef1033dea239875dd00dfb4fee6e3348b84985c92f103444683bae07b83b5c38e5e2b0c8529d7fa3f64d46daa1ece2d9ac14cab9477d042c84c32ccd0 046e145ccef1033dea239875dd00dfb4fee6e3348b84985c92f103444683bae07b and when the value of y needed for verification It is confirmed that the public key has not been forged by arithmetic on the y value by the above-described elliptic curve function expression and verifying that the coordinates exist on the elliptic curve function graph.

In the present invention, a private key and a public key are generated by the algorithm as described above, the public key is used for log-in information and cryptocurrency transmission, and the private key is cross-correlated with the public key to verify the authenticity of each individual and use it for digital signature. .

In addition, when the password is forgotten or the application is reinstalled with the digital signature of the private key, a new password is created or existing data is restored instead of the request for name, resident registration number, phone number, etc. With the same algorithm, one private key generates only one public key and uses it as an account address to identify each individual and allows users to log in to the platform by entering a password.

The user of the first terminal 200 may be authenticated using a password and the identifier. In this way, an encrypted channel is established between the first terminal 200 , the second terminal 300 , and the platform server 100 .

6 is a detailed flowchart of exchanging advertisement information between the first terminal and the platform server according to the present invention. Referring to FIG. 6 , the broadcasting station system 500 transmits advertisement broadcasting information to the TV 210 using a broadcasting communication network ( S510 ). Here, the commercial information includes commercial information including general image information. The TV 210 displays an image corresponding to the corresponding commercial information in real time by using the received commercial information.

In this case, the first terminal 200 sets a communication channel and detects a viewing channel using the TV 210 and wireless or wired communication (S520). Communication channel setting is set by applying a known technique to be set between the first terminal 200 and the TV 210 . In addition, a method of detecting a viewing channel through which the user of the first terminal 200 is watching the TV 210 will be described later.

For digital TV signals and cable TV signals, ATSC (Advanced Television System Committee), a commercial standard, is applied. In case of digital TV, data of 19.28Mbps is transmitted on 6MHz channel, and in case of cable TV, 6MHz It transmits 38.56Mbps data on the channel.

Here, the signal frame structure of the viewing channel of digital TV and cable TV is configured as a binary data frame structure for transmitting data packets after randomization and error correction encoding of input data is performed.

The detailed frame structure consists of two fields, and each field consists of 313 data segments. Among the 313 data fields, a first segment is allocated as a field synchronization signal for synchronizing between fields, and the remaining 312 segments are allocated with a segment synchronization signal for synchronizing data and segments.

Here, the 312 segments are composed of 832 symbols, and the first 4 symbols among the symbols allocate a segment synchronization signal for synchronizing between segments. For the remaining 828 symbols, a data transmission packet and an additional symbol that is forward error correction (FEC), that is, an error correction additional packet, are allocated. The 828 symbols are modulated with 8 level signals, that is, 8VSB (Vestigial Side Band) is modulated and transmitted.

In the 8VSB modulation process, the 8-level symbol and the field sync signal combined with the segment sync perform Suppressed-Carrier modulation on a single carrier. In the modulation process, most of the lower sideband is removed, and the transmitted power spectrum is a power complex signal having a Square Root Raised Cosine Response (Power Spectrum) except for a 620KHz transition region. is flattened. At this time, the pilot signal, which is one of the synchronization signals, is inserted at a frequency 310KHz away from the end of the low frequency band.

간격으로 규칙적으로 반복된다. Through this process, one complete segment is composed of 832 symbols, among which the first 4 symbols are segment synchronization signals, and the remaining 828 symbols are composed of data and additional symbols. The segment sync signal is 2 levels (±5) and the same sync pattern is 77.3

repeated at regular intervals.

For example, the segment synchronization signal and the field synchronization signal may have arbitrary values of -5 level and +5 level, and after matching the segment synchronization signal and the field synchronization signal with the symbol, the level -5, + A pilot carrier may be generated by adding 1.25 to level 5.

Based on the position and energy distribution of the pilot signal of a specific frequency band signal generated through this process, it may be possible to measure the frequency in a short moment even in a very weak use environment. Also, as an example, the specific frequency band signal may have a commercial standard Advanced Television System Committee (ATSC) frame structure.

Here, as the pilot signal detection technology, a pilot spectrum detection technology based on a well-known Fast Fourier Transform (FFT) may be applied. As described above, the received signal frame of the viewing channel of digital TV and cable TV includes a pilot signal, demodulating the pilot signal to a baseband, and using a low-pass of 40KHz (± 20KHz). After filtering, it is down-sampled to 1/400 again, and the length of the pilot signal detected through the FFT process is flexibly changed according to the detection period. Here, signal detection is performed by comparing the maximum value of the square value of the detected pilot signal length as a result of each FFT with a threshold value, and if all of the result values of the detected pilot signal length are added to be greater than the threshold value, the channel of the corresponding frequency is being viewed. determined by channel.

Here, the threshold value may be set using a Constant False Alarm Rate (CFAR) algorithm.

The TV 210 receives a broadcast signal from the broadcasting station system 500 , and the broadcast signal received by the TV 210 includes a frequency of a viewing channel and an added carrier, that is, a pilot signal. At this time, the first terminal 200 detects a carrier wave generated from the received broadcast signal, and detects a pilot signal included in the carrier wave.

12 to 14 again, signal detection is performed by comparing the maximum value of the squared value of the detected pilot signal length with a threshold value, and if all the result values of the detected pilot signal length are added to a value greater than the threshold value, the corresponding frequency detected with

Also, the first terminal 200 stores and updates the channels and frequency bands for digital TV and cable TV broadcasting shown in FIGS. 12 to 14 . The first terminal 200 determines the corresponding channel by comparing the digital TV and cable TV broadcasting channels and frequency bands with the detected pilot signal length.

For example, if the detected pilot signal length and the corresponding frequency are 54.31 MHz in the lower band and 59.69 in the upper band, the first terminal 200 compares with the frequency band of the digital TV and cable TV broadcasting channels, It is determined within the range of 54 MHz to 60 MHz of the frequency band, and the channel being viewed is determined as channel 2.
