Abstract

The invention discloses a voiceprint authentication method and a device. The voiceprint authentication method comprises steps of displaying a character string to a user, wherein the character string comprises a preference character set by the user, and the preference character set by the user is displayed in the character string as a symbol corresponding to the preference character, obtaining voice of reading the character string by a user, obtaining a voiceprint recognition vector of the voice, performing comparison between the voice voiceprint recognition vector and the voiceprint recognition vector registered by the user, and determining the voiceprint authentication result. The invention improves the safety of the payment through comparing the user voiceprint, doesn't need the password inputted by the user and doesn't need the verification password, improves the convenience and payment efficiency in the usage process, satisfies the psychological demand of not hoping that the password is displayed, enhances the user experience and improves the usability of the voiceprint password.
