PURPOSE:To prevent an access to the system of another person by registering the voiceprints of respective operators in advance and comparing the voiceprint of an inputted voice for pass-word and the voiceprint of the operator. CONSTITUTION:In a voiceprint accumulating part 1, the voiceprint to be registered at first from an external part is accumulated. On the other hand, when the access is executed to the system, the voiceprint of the operator, who executes the access, is picked up from the voiceprint accumulating part 1 to a voiceprint comparing part 3 by an ID detecting part 2. When the voiceprint is picked up, the input instruction of a voice pass-word is sent from a voice input and output part 4 to the input operator. When the pass-word is inputted by the voice of the input operator, the voiceprint is inputted to a voiceprint analyzing part 5 and an analyzed result is sent to the comparing part 3. Then, the comparison of the voiceprint is executed. When the both voiceprints are coincident, it is outputted that the pass-word is passed and the access to the system is allowed. |
