摘要

The present invention relates to a personal information infringement prevention method and system, in which biometric authentication and phase division of an authentication process are combined. A personal information infringement prevention system in which biometric authentication and phase division of an authentication process are combined according to the present invention comprises: a portable terminal in which an application capable of photographing a QR code and performing biometric recognition is installed, wherein when biometric recognition provided through the application is completed, the portable terminal stores input personal information and encrypts the personal information by using a value included in the QR code so as to transmit the encrypted personal information, or loads and transmits a previously stored ID; a service server for storing the encrypted personal information, generating a user ID, and transmitting the user ID to the portable terminal for storage, or notifying the portable terminal of completion of logging-in when the ID received from the portable terminal is a valid ID; and a key server for generating a key value for encryption and decryption of the encrypted personal information, classifying and storing the key value for each user, and providing the key value to the service server.
