Abstract

The present invention facilitates the change of a voice password in the vocal print authentication. A vocal print authentication system includes voice recording means for recording vocal print data of single elements of numbers and/or letters which constitute a password and vocal print data of link elements which links the respective single elements for every registrant, password forming means for forming a random password using the respective elements, vocal data forming means for forming vocal data of the password which is formed by the password forming means using the vocal print data, and password determination means for determining whether a determination requesting person is the registrant or not based on the collation between vocal data which is obtained due to the inputting by voice of the password by the determination requesting person and the vocal data which is formed by the vocal data forming means. In place of registering the voice password per se which is obtained by uttering the password, the vocal print data of the respective elements which constitute the password are registered.

Claims

1. A vocal print authentication system comprising:

voice recording means for recording vocal print data of single elements of numbers and/or letters which constitute a password and vocal print data of link elements which links the respective single elements for every registrant;

password forming means for forming a random password using the respective elements;

vocal data forming means for forming vocal data which is obtained by vocalizing the password formed by the password forming means using the vocal print data; and

password determination means for determining whether a determination requesting person is the registrant or not based on the collation between vocal data which is obtained due to the inputting by voice of the password by the determination requesting person and the vocal data which is formed by the vocal data forming means.

2. A vocal print authentication system according to claim 1, wherein the link elements are elements which indicate digits of the number and/or elements of symbol.

3. A vocal print authentication system according to claim 1, wherein the voice recording means records the vocal print data in association with an ID which is intrinsically set to each registrant, and the password forming means starts the formation of the password based on the recognition of the ID.

4. A vocal print authentication system according to claim 1, wherein the vocal print authentication system includes password request means which forms a question which requires inputting by voice of the password and requests the determination requesting person the inputting by voice of the password for the formed question.

5. A vocal print authentication system according to claim 1, wherein the vocal print data recorded by the voice recording means includes a predetermined authentication range based on the inputting of a plurality of voices for each same element obtained from the registrant.

6. A vocal print authentication system according to claim 1, wherein the password forming means selects an arbitrary number of single elements from the respective single elements constituted of the numbers and/or letters, wherein the arbitrary number is at least two or more, and the password is formed by arranging the selected single elements in arbitrary order.

7. A vocal print authentication system according to claim 1, wherein the vocal data forming means takes out the vocal print data corresponding to the respective single elements which the password formed by the password forming means includes from the voice recording means, the vocal print data is arranged in accordance with the arrangement order of the single elements of the password, and the link elements are inserted between the respective single elements thus forming the vocal data of the password.

8. A vocal print authentication system according to claim 1, wherein the vocal data forming means takes out the vocal print data corresponding to the respective single elements which the password formed by the password forming means includes from the voice recording means, the vocal print data is arranged in accordance with the arrangement order of the single elements of the password, and the link elements are inserted between the respective single elements thus forming the vocal data of the password, and

the password determination means samples vocal data of the respective elements which form the password by analyzing the voice which the determination requesting person inputs, and compares the sampled vocal data and the vocal data formed by the vocal data forming means for every element.

9. A vocal print authentication system according to claim 1, wherein the vocal data forming means takes out the vocal print data corresponding to the respective single elements which the password formed by the password forming means includes from the voice recording means, the vocal print data is arranged in accordance with the arrangement order of the single elements of the password, and the link elements are inserted between the respective single elements thus forming the vocal data of the password, and

the password determination means samples vocal data of the respective elements which form the password by analyzing the voice which the determination requesting person inputs, and compares the sampled vocal data and the vocal data formed by the vocal data forming means based on a voice level of the serial password and/or a time interval between respective elements.

10. A vocal print authentication system according to claim 1, wherein the password forming means forms the password by incorporating the single elements of the numbers and/or the letters at predetermined positions in a sentence which forms the password.

11. A vocal print authentication system according to claim 1, wherein the vocal data forming means forms the vocal data of the password

by sampling the vocal print data corresponding to the respective elements which the password formed by the password forming means includes from the voice recording means, and

by arranging the sampled vocal print data at positions where the respective elements in a sentence which forms the password are arranged.

12. A vocal print authentication system according to claim 1, wherein the vocal data forming means forms the vocal data of the password
