음성인식기술을 이용한 전자상거래 인증 시스템{Authentication system for electric commerce using voice recogniton technigue}Authentication system for electric commerce using voice recogniton technigue}

본 발명은 화자종속 방식의 음성인식 기술을 이용한 전자상거래 인증 시스템에 관한 것으로, 특히 컴퓨터에 연결되어 있는 마이크를 이용하여 본인의 음성(또는 지문, 홍채, 문자비밀번호)암호를 미리 등록해 놓고 이 음성암호확인시스템을 채택한 쇼핑몰이나 금융권의 인터넷 뱅킹 및 증권 거래시스템에 연결하여 카드결제 또는 자금이체를 할 경우 본인 확인을 위하여 자신이 미리등록해 놓은 컴퓨터에 연결되어 있는 마이크를 이용해 확인하여 카드분실 또는 문자 비밀번호 유출시에도 안심하고 전자상거래를 활용할 수 있도록 한 것이다.The present invention relates to an electronic commerce authentication system using a speaker-dependent speech recognition technology. In particular, a voice (or fingerprint, iris, text password) password is registered in advance using a microphone connected to a computer. Card payment or money transfer when connected to the internet banking and securities trading system of the shopping mall or financial sector that adopts the password verification system, and confirmed by using the microphone connected to the computer registered in advance for identity verification. Even when a password is leaked, you can use e-commerce with confidence.

최근 2-3년 사이 전자상거래 시장이 급속한 확장을 하고 있으나 개인정보 유출 우려에 따른 카드결제 기피현상으로 EC산업 방전의 장애 요인이 되고 있다. 또한, 주민등록번호나 카드번호 유출에 따른 후유증도 심각한 상태이며, 전자화폐가 속속 등장하고 있으나 실효성에는 의문이 되고 있다.The e-commerce market has been expanding rapidly for the past 2-3 years, but it has been an obstacle to the discharge of the EC industry due to the avoidance of card payments due to concerns about personal information leakage. In addition, the sequelae after the leakage of the social security number or card number is also a serious condition, and electronic money is appearing one after another, but its effectiveness is questioned.

쇼핑몰 또는 금융권에는 보안시스템의 필요성에 대해서는 충분히 인식하고 있으나 설치 비용과 신뢰성에 대한 확신이 없는 상태이므로 서로 눈치만 보고 있는 실정이다.The shopping mall or the financial sector is fully aware of the necessity of the security system, but since they are not convinced of the installation cost and reliability, they are only looking at each other.

종래의 카드결제 방법은 도 1에 도시된 바와 같이 PC를 가진 사용자가 인터넷을 이용해 쇼핑몰에 접속하고 원하는 상품을 선택한 후 현금 결제 또는 카드 결제를 선택한다(S1,S2).In the conventional card payment method, as shown in FIG. 1, a user having a PC accesses a shopping mall using the Internet, selects a desired product, and then selects cash payment or card payment (S1 and S2).

만일 카드결제를 선택할 경우, 카드번호를 입력하고 비밀번호 누출을 우려하여 카드유효기간만 입력받으며, 이때 카드 유효기간은 카드에 명시되어 있으므로 누구나 입력할 수 있다(S3-S5).If you choose to pay the card, enter the card number and only the card validity period is entered in fear of password leakage, the card validity period is specified on the card anyone can enter (S3-S5).

현재의 쇼핑몰에서 운영되는 모든 결제 시스템은 카드 결제시 한국정보통신의 시스템에 연결하여 카드의 이상유무를 판단하며 분실신고된 카드인지 아닌지를 확인한다(S6).All payment systems operating in the current shopping mall are connected to the system of the Korea Information and Communication when the card payment to determine the abnormality of the card and to confirm whether or not the card reported (S6).

분실신고되지 않았고 카드유효기간이 이상이 없을 경우 한국정보통신의 시스템에서는 카드에 아무런 이상이 없다고 알려주며, 쇼핑몰에서는 이상이 없는 카드로 판단하고 상품대금 만큼의 금액을 카드결제한다(S7,S8).If it is not reported lost and the card validity period is not abnormal, the system of the Korea Information and Communication notifies that there is nothing wrong with the card, the shopping mall judges that there is no abnormality and pays the amount as much as the product price (S7, S8).

그러나 이와 같은 종래의 방법에 있어서는 카드를 분식하고 분실신고를 하지 않은 경우 쇼핑몰에서 얼마든지 물건을 구입할 수 있으며 이로 인한 피해가 급격히 늘어나고 있는 추세이다.However, in such a conventional method, if a card is classified and lost is not reported, the user can purchase any number of items at a shopping mall, and the damage caused by this is rapidly increasing.

또한, 이러한 문제점 때문에 사용자가 카드결제를 기피하고 있으므로 전자상거래 시장이 활성화되지 못하고 최근 급격히 보급된 인터넷 환경을 제대로 활용하지 못하여 경제적인 손실이 큰 실정이다.In addition, due to these problems, the user avoids the payment of the card, so the electronic commerce market cannot be activated, and the economic situation is large because it is not able to utilize the recently rapidly spread internet environment.

최근 이와 같은 문제를 해결하기 위해 전자화폐 또는 사이버머니 등이 개발되었지만 이 또한 분실시 대책이 미흡하여 효율성이 없는 실정이다.Recently, electronic money or cyber money has been developed to solve such problems, but this situation is also inefficient due to insufficient measures for loss.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 본 발명의 목적은, 인터넷 쇼핑몰에서 카드결제를 희망하는 사람이 미리 자신의 음성암호를 음성암호확인시스템에 등록해 놓고 기술협력을 체결한 쇼핑몰 또는 은행, 증권회사의 인터넷 사이트에 연결하여 원하는 상품을 선택한 후 카드결제시 본인의 음성암호를 한번 더 확인하는 음성인식기술을 이용한 전자상거래 인증 시스템을 제공하는데 있다.The present invention has been made in order to solve such a conventional problem, the object of the present invention, the person who wishes to pay the card in the Internet shopping mall registered his voice password in advance in the voice password confirmation system and concluded technical cooperation It provides an electronic commerce authentication system using voice recognition technology that checks the user's voice password once more by selecting a desired product by connecting to an Internet site of a shopping mall or a bank or a securities company.

본 발명의 다른 목적은, 음성뿐만 아니라 지문인식이나 홍채인식기술을 이용하여 보다 정밀한 보안검정을 할 수 있으므로 누구나 안심하고 카드결제를 함으로써 전자상거래를 활성화시켜 산업발전에도 크게 기여할 수 있는 음성인식기술을 이용한 전자상거래 인증 시스템을 제공하는데 있다.Another object of the present invention is to provide a voice recognition technology that can contribute to the development of the industry by activating the electronic commerce by paying the card with confidence because it is possible to perform a more precise security test using fingerprint recognition or iris recognition technology as well as voice. The present invention provides an electronic commerce authentication system.
