The present invention relates to a method for preventing a digital signature input error, and more particularly, when a character or a symbol is input to an electronic signature input unit in the certified certificate guide window, the format of the first input data is specified in a specific area of the authorized certificate guide window. Displayed in a separate display window, the user can check whether the input data displayed as an asterisk on the digital signature input unit is inputted in data of Korean, English, or English, including capital letters, lowercase letters, numbers, special symbols, etc. It is about how to prevent the error of digital signature input in the certification certificate guide window.

An accredited certificate is a certificate issued by a government-certified national certification authority for the purpose of preventing the identification and hacking of the trading party to ensure the secure transaction establishment in the Internet electronic transaction. After the direct visit, the certificate-related application must be downloaded from the issuer server through the Internet, and then a public certificate must be installed according to a predetermined procedure. The accredited certificate includes the version of the certificate, the serial number of the certificate and the name of the validating authority, the name of the issuing organization, the digital signature verification information of the subscriber, the name and identity verification information of the subscriber. If the password is entered in the certificate password field of the window, the authentication process is performed by attaching the digital signature to the certificate.

As in the official certificate, in the secure click service or the secure payment service, the transaction is established only by inputting the authenticated password without inputting any other information during electronic commerce, so that the password is entered in a separate window after entering the payment information. In the case of a service, an authorized certificate must be installed on the computer to be used.

The authentication confirmation services are a method for ensuring a secure e-commerce, security maintenance is particularly important when using the above-described service, and in general, when the authentication confirmation password is input as shown in FIG. In this way, information leakage is prevented. However, if the user forgets the password, or if he or she does not know the data format such as entering English in Korean or Korean in English and repeats the wrong password a predetermined number of times, a certificate authentication error occurs from the certificate program. If the authentication check error occurs, the corresponding certificate cannot be used.

In order to minimize the occurrence of an error in the password input because the user has to visit the certificate issuer directly to apply for a certificate or change the password in order to use the certificate after the authentication confirmation error occurs. There is a need for a technology development related to a method of confirming the format of cryptographic data displayed in asterisks on a display.

An object of the present invention devised to solve the above problems is that when a data is input to an electronic signature input section of a certified certificate guide window, a predetermined display window is activated on the display to display the format of the first data and when the second data is input. Provides a method for preventing an electronic signature input error, which prevents an error in inputting a digital signature by allowing the display window to be extinguished, or confirming each type of data for each input data while the display window is activated while data is input. It is.
