Abstract:
1. A voice authentication method using a removable voice ID card, comprising the following steps: a user inserting the voice ID card storing a voiceprint of the authorized user into a client; the client requesting from a server a voiceprint digest corresponding to the voiceprint in the voice ID card; the client generating a second digest of the voiceprint in the voice ID card; comparing said two voiceprint digests; performing a voice authentication process in case of the two digests matching and in response to determining that the two digests match, generating a text script as a pass code, and in response thereto, receiving a voice inputted by the user; generating a semantic meaning of the voice inputted by the user; and judging whether the semantic meaning is the same as the text script generated by said random pass code generator, thereby determining whether said user can be authorized.
