Description

Wired and wireless internet-based lottery service method and system {METHOD AND SYSTEM FOR SERVICING A LOTTERY TICKET BASED ON A WIRE / WIRELESS INTERNET SCHEME}

The present invention relates to a lottery service system using the wireless Internet, and more particularly to a wireless internet lottery service system using a digital voiceprint comparison method for identifying the lottery buyers.

In general, the lottery ticket release method includes a ticket type release method, a release method using a wired Internet, a lottery release system using an ARS, and the like.

Ticket-type release methods are currently operated by most lottery issuance methods, and the type of operation is to issue lotteries by the issuing agency (for example, a housing bank in the case of a housing lottery), and the relevant banks and agencies provide sales agents and supply agents. This is done by distributing tickets and paying some fees to agents.

However, this method has a complicated distribution structure between the issuer and the agency, and the sales are centered on small retail stores, which makes accurate counting and efficient operation of sales impossible. In addition, excessive costs and the complexity of the distribution structure reduce profits for the customer and notification of winnings is impossible without the existing mass media.

The lottery sale method using the wired internet is a method of selling a lottery using the wired internet, which is derived from an effort to escape a small sales office. In this method, a customer purchases a lottery ticket by accessing a lottery ticket sales server through the Internet using a computer. The sales method has advantages over ticket-type sales in that there is no need to find a sales office, but it is still difficult to freely access the Internet anywhere in the country and purchases only with a password and social security number, so the accuracy of identity verification is reduced, and security of internet communication This is a problem. In addition, the payment method is very inconvenient, such as having to use a card to pay for the lottery.

Recently launched lottery ticket using ARS (Automatic Response System), the person who wants to apply for the lottery, after purchasing the lottery prepaid card, access the central computer center, your social security number, prepaid card ID, The lottery card will continue to be recharged by entering a password to enter the lottery. Since this method uses a telephone, the user's voice is recorded and used as a material for later verification. This approach has overcome some of the above drawbacks, but the following issues remain.

First, it is a problem of the lottery prepaid card used to collect the application amount of the user. As it is inconvenient to use it continuously, it is inconvenient to pay the bill like the lottery method through the Internet.

Second, ARS cannot be accessed and used where there is no card phone.

Third, there is a problem of whether or not the person remains in a way that a person simply identifies himself by ear by recording the voice.

Therefore, an object of the present invention is to provide a wireless internet-based browsing system lottery service method and system that solves the security problem of the electronic lottery system of the prior art by a digital voice analysis method.

A lottery service method according to the present invention for achieving the above object comprises the steps of: accessing the lottery server system through the wireless network operator using a browser-embedded wireless terminal; Storing, in a database, lottery information including a lottery type, number, quantity, purchase method, and winning time in a database according to an input screen provided to the wireless terminal in the lottery server system; Receiving voice data certifying that the lottery purchaser has provided lottery information through the wireless terminal and storing the received voice data in a database; Drawing a lottery winning number to retrieve the winning lottery buyer from the database; Comparing voice data of the winners provided from the searched lottery winners with voice data of the buyers stored in the database to determine whether the lottery buyers are the same as the winners; And notifying the confirmed lottery buyer of the lottery winning fact.

According to another embodiment of the present invention, a lottery service system connected via the Internet to provide a lottery service comprises: a lottery server system connected to the Internet; It includes a wireless terminal for accessing the lottery server system through a wireless network operator using a built-in wireless browser,

The lottery server system includes: a lottery information database storing information related to lottery provided to a purchaser connected through the wireless terminal and a wired terminal; A transaction processing module which controls the lottery information database to process a transaction between the lottery buyer and the lottery service system; A voice database for storing a voice for proving the identity of the lottery buyer occurring in a transaction between the lottery buyer and the lottery service system; And a voice analysis module for verifying whether the lottery buyer and the lottery winner are the same by comparing the lottery buyer and the lottery winner who are stored in the voice database through interworking with the transaction module.

100: wireless terminal 200: wireless network operator system

300: Internet 500: Lottery Server System

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows an overall network configuration of a lottery service system according to the present invention. As shown in the drawing, the lottery service system includes a wireless network operator system 200 including a gateway, a client group including a wireless terminal 100 and a user computer 150 for wireless transmission, and a wireless network through the Internet 300. It consists of a lottery server system 500 is connected to the operator 200.

The wireless terminal 100 of the lottery buyer has a built-in WAP (Wireless Application Protocol) browser, the wireless network operator system 200 is a gateway according to the Internet connection request by the lottery buyer using the WAP browser of the wireless terminal 100 It serves to access the Internet 300 through. Meanwhile, the user computer 150 owned by the lottery buyer has a built-in WAP (Wireless Application Protocol) browser and a web (WEB) browser, and can directly access the Internet 300 through an unshown public network using a browser.

The lottery server system 500 of the present invention is connected to the Internet 300 which can be accessed by the wireless network operator system 200 based on WAP and mobile browsing technology, which is currently established as a new standard of the wireless Internet 300. It is a lottery system that exists as an independent server. Therefore, the wireless network operator system 200 and the server system 500 do not need to be directly connected, and wherever the Internet 300 exists, the system can be installed and operated anywhere and a buyer who wants to purchase a lottery is equipped with a WAP browser. After accessing the system 500 through the Internet 300 using the wireless terminal 100 or the computer 150 with the built-in web browser, the necessary lottery can be ordered, purchased, modified, and canceled according to a desired method.

The lottery server system 500 includes a proxy server 510, a WAP / WEB server 520, a transaction processing module 530, a voice analysis module 540, a lottery information database 550, and a voice storage database 560. do.

As is known, the proxy server 510 is used for security purposes and cache functions, and the WAP / WEB server 520 serves to provide a wired Internet environment and a wireless Internet environment.

The transaction processing module 530 controls the lottery information database 550 so that the lottery buyer can provide various information provided by the lottery server system 500 through the wireless terminal 100 or the computer 150, for example, a lottery purchase method. It handles the transaction between the lottery buyer and the server system 500 in a two-way (TWO-WAY) way to freely select the desired one, such as the form of the lottery, the lottery number designation, the desired winning time.

The voice analysis module 540 is provided from the buyer at the time of purchase of the lottery in addition to the general self-identification information such as ID, social security number, etc. entered by the lottery buyer processed by the transaction processing module 530 to prove his or her identity, to the voice database 560. It performs the function of confirming the identity of the buyer who wins the lottery by analyzing and comparing the temporarily stored voice and the voice of the buyer who wins the lottery.

According to the present invention, the analysis method performed by the speech analysis module 540 is a voice analysis based on a parameter extraction method of a digital speech waveform rather than an existing analog analysis method, and the buyer and the winner's voice stored in the speech database 560. The accuracy is almost the same as that of fingerprints in a way that analyzes and contrasts and confirms that they are the same person. It may also be configured to request authentication from a third party certification authority if necessary.

2 shows a flow diagram illustrating a digital voice analysis process performed by the voice analysis module 540.

First, the voice analysis module 540 converts the voice provided at the time of purchasing the lottery from the lottery buyer to a digital file of the WAV and VOC files through a sampling process (step 210). In this case, the sampling frequency should generally be 10 kHz or more, digitize to 12 bits or more, record it, remove the noise through a filter, and divide it into syllable units for comparison. In this regard, FIG. 3A shows a sound source waveform sampled in units of syllables of a buyer.

The speech analysis module 540 then performs the necessary parameters, such as negative energy, as shown in FIG. 3B, as shown in FIG. 3C, from speech data in syllable units converted to digital signals. Negative pitch period, formant as shown in FIG. 3D, power spectrum density as shown in FIG. 3E, and cepstrum as shown in FIG. 3F. The coefficients are extracted (step 220).

As such, the buyer's speech parameters analyzed by the speech analysis module 540 are temporarily stored in the speech database 560.

Subsequently, the server system 500 of the present invention draws the lottery winner after a certain period of time, receives a voice from the winner, and extracts the winner's voice parameters through the same process as described above. Therefore, the voice analysis module 540 determines whether the lottery buyer and the lottery winner are the same by determining a pattern match between the buyer's voice parameter stored in the voice database 560 and the winner's voice parameter. The pattern matching determination may be performed by comparing the similarity between the buyer's voice parameter and the winner's voice parameter with a predetermined reference value.

The comparison process performed in the speech analysis module 540 of the present invention will be described with reference to one parameter, for example, power spectral density.

Looking at the power spectrum recorded by extracting from different speakers illustrated in FIGS. 4A and 4B, it can be seen that the shape of the waveform is markedly different. In particular, the middle band of frequencies is the main object of comparison, and whether the peak values for each frequency appear in a similar form is an important determinant for the speaker's identity.

In general, there are two drawbacks when applying VQ technique for speech recognition as it is to speaker recognition. First of all, there are several feature parameters for speaker recognition. Second, one parameter goes through unnecessary steps such as codebooks. Therefore, in order to overcome the above problem, the present invention uses a similar VQ model to increase the number of comparison characteristic parameters than the general VQ and simplify the comparison method.

A feature of the pseudo VQ modeling technique is that each data is vectorized with discrete values for 4-5 major speech parameters. For example, in the case of power spectral density, data values at regular intervals are extracted for a proper interval of each frequency into a set.

For example, in Figure 4a, for frequencies 0-1000 x ₁ = (70, 75, 80, 90, 80, 90, 81, 89, 80, 75, 71, 68, 66, 61, 58, 57), frequency In the case of 1000 to 2000, the vector x = (x ₁ , x ₂ , .x _n ) is obtained by extracting equally spaced data such as x ₂ = (58, 54, 51...).

As such, when sampling is performed on the speaker representing the power spectral density of FIG. 4A, the next step is to obtain a vector y in the same manner for the speaker representing the power spectral density of FIG. 4B.

Then, for comparison between the two, mapping the vectors x and y establishes the following relationship, and the mapping between these sets of vectors is called pseudo quantization.

y = q (x)

Quantizing x and y as above defines a quantum error and a distortion measure d (x, y). The distortion measurement used here uses a typical Euclidean distortion measure and its definition is as follows.

d (x, y) = (xy) W ^-1 (xy) ^T

The total distortion (D) for all segmented sections may be obtained by using Equation 3 below.

The total difference between two sound sources is calculated using D, and this value converted to a number shows that the two sound sources are different speakers when the two sound sources exceed the general error range.

This can be expressed by the following equation (4).

In the above equation, D _pd is the power spectral density total distortion, S is the scaling factor, and ε represents the error. At this time, when the comparison value is smaller than the error, it is recognized as the same speaker.

As described above, the same method is applied to the remaining parameters, energy, pitch period, formant, and septum coefficient to identify the same person. Of course, there is a scaling factor according to the range of values for each parameter characteristic. The range of error is about 0-35% based on percentage, and if it exceeds, it is proved that it is not the same speaker.

The operation of the lottery service system of the present invention having the above-described configuration will be described in more detail with reference to FIG. 5 below, and in particular, a process performed using the wireless terminal 100 will be described.

First, the lottery purchaser begins with a step 610 of accessing the Internet 300 using his WAP browser embedded wireless terminal 100. When the request for accessing the internet 300 of the lottery purchaser is received by the wireless network operator system 200 by radio wave, it is connected to the Internet 300 through a gateway through a central network of the wireless network operator.

In the next step 620, when a buyer's request is received by the lottery server system 500 connected to the Internet 300, the transaction processing module 530 of the lottery server system 500 is connected to the buyer's wireless terminal 100 The first response is processed in the appropriate language format (WML, HTML, XHTML, XML) according to the browser status of the web browser and the initial screen information necessary for purchasing the lottery is transmitted to the WAP / WEB server 520 and the WAP / WEB server 520 transmits it to the purchaser's wireless terminal 100 via the proxy server 510 via a wired / wireless network. Therefore, the screen information sent from the lottery server system 500 is displayed in the browser of the wireless terminal 100 of the buyer. In this case, communication between the lottery server system 500 and the wireless terminal 100 of the browsing method is typically to exchange data in the S-HTML, HDML, WML, HTML, XHTML, XML format by HTTP (Hyper Text Transfer Protocol) . From this stage, the wireless network operator system 200 serves only as a simple information medium between the lottery buyer's wireless terminal 100 and the lottery server system 500, and the input and response therebetween are mutually responsive between the buyer and the present system. Proceed by TWO-WAY.

Thereafter, in step 630, when the lottery purchaser comes up the homepage of the lottery server system 500 in the browser on the wireless terminal 100, the contents displayed on the browser are the direction keys of the wireless terminal 100, or the wireless terminal 100. By using the pointer of the) or through the touch screen of the wireless terminal 100 to input the intention to purchase the lottery ticket by clicking on the desired function, that is, the lottery purchase button on the home page.

In a next step 640, as illustrated in Figs. 6A, 6B and 6C, the transaction processing module 530 of the lottery server system 500 may purchase buyer information such as a social security number and password to confirm the purchaser's membership. To enter, the buyer enters his name, password, social security number before purchasing the lottery. At this time, the purchaser registered as a member reads the subscriber ID from the header information transmitted from the wireless terminal 100 to the server system 500 and receives only the password. If you are not a member, you may be encouraged to join.

Next, as illustrated in FIG. 6D, the buyer inputs the type, quantity, purchase method, and winning time of the desired lottery according to the terminal screen provided by the lottery server system 500. At this time, as shown in Figure 6e, if you have selected a lotto (lotteto) lottery ticket in the purchase method enters the desired lottery number (step 650).

In a next step 660, as illustrated in FIG. 6F, the transaction processing module 530 of the lottery server system 500 searches the lottery information database 550 to verify the validity of the lottery number entered by the purchaser. In the case of a regular lottery, if a lottery number has already been applied for by another user, it is required to re-enter it. Lotto-type lottery ticket is validated according to the limit if there is a limit to the same number, and notifies the buyer of how many current number inputters, and accordingly the buyer can reselect.

In a next step 670, as illustrated in FIG. 6G, the transaction processing module 530 requests voice recording for identity verification of the lottery buyer, and the voice analysis module 540 receives the voice signal input from the buyer. The data is converted into digital data, and various parameters are extracted and analyzed from the digital data and stored in the voice database 560. The buyer's voice parameters stored in the voice database 560 are then used to determine whether the same person is compared with the voice parameters of the winners who have received and processed the voice in the same manner when paying the lottery prize.

The next step 680 is a step in which the purchaser selects the payment now method provided by the transaction module 530, as illustrated in FIG. 6H, where the payment method is a credit card or a mobile phone fee in the case of a member. It can be, in the case of a non-member may be configured to enable payment by mobile phone bill.

In a next step 690, as illustrated in FIGS. 6I and 6J, the transaction processing module 530 sends a message confirming that the buyer's input is correct, confirming the buyer's selection and ending the connection. do. At this time, the transaction processing module 530 stores the contents entered by the buyer in the lottery information database 550, and if necessary, in order to prepare for any external hacking threats or data loss, the certificate authority that is not connected to the network, It can also be duplicated and stored in multiple places.

Thereafter, the lottery ticket is drawn after a certain period of time, the result is reflected in the lottery information database 550, and the winner is notified of the message as illustrated in FIG. 6K using the push function (step 700). At this time, the notification message transmitted from the transaction processing module 540 to the wireless terminal 100 of the buyer is linked to the address of the lottery server system 500 so that the lottery buyer checks the winnings and accesses the lottery system 500 to purchase the lottery ticket. Retype the same password you used.

Then, the voice analysis module 540 listens to the voice content identical to the voice content input at the time of purchase of the lottery from the winner (step 710), and stores the buyer's data stored in the voice database 560 using the digital voice analysis method as described above. Each voice parameter is compared with each voice parameter of the newly input and processed winner to confirm that they are the same person (step 720).

In this regard, for the purpose of proving the same identity of the buyer and the winner, it has been described by pre-extracting the buyer's voice parameters, but alternatively, both the buyer and the winner's voice are stored in the voice database 560 and the respective parameters are extracted from them. It may also proceed in a comparative manner.

Thereafter, if it is confirmed that the buyer and the winner are the same person, the winner is paid (step 730). The payment of the winnings is made by the payment method that the winner wants, and the buyer can use the winnings again to purchase the lottery, or receive the winnings by reducing the fee or receiving the fee of the wireless terminal 100 directly. .

As described above, the present invention is easy to use, fast, accurate purchase of a lottery for a purchaser having a built-in browser can be made up to verify the identity exactly when winning. In addition, the present invention can overcome the limitations of autonomous lottery options and lottery access methods that have been a problem in the conventional off-line lottery release, and the problem in the lottery release on the online (line) Overcoming the registrant's cliche and security weaknesses can be overcome.
