Abstract

In the present invention, an electronic apparatus adds user information to print information and transfers the print information, to which the user information has been added, to an image processing apparatus. The image processing apparatus specifies a voice feature based on the user information received from the electronic apparatus, specifies user-authentication information by executing voice authentication processing based on the specified voice feature, and starts output of the print information based on the specified user-authentication information. Hence, it is possible to output print information after assuredly authenticating a regular user, and start output of the print information according to an instruction only from the regular user.

Claims

1. An image processing system, comprising an electronic apparatus and an image processing apparatus, for forming an image based on print information transferred from said electronic apparatus to said image processing apparatus, said electronic apparatus comprising:

information addition means for adding a user identifier to the print information; and

transfer means for transferring the print information having the user identifier added thereto to said image processing apparatus,

said image processing apparatus comprising;

voice-feature specification means for specifying a voice feature based on the user identifier added to the print information by referring to a table for storing the voice feature in correspondence with the user identifier;

voice-feature extraction means for extracting a voice feature from a voice input from the user;

user-authentication means for authenticating the user by comparing the voice feature specified by said voice-feature specification means with the voice feature extracted by said voice-feature extraction means; and

print-information output means for starting output of the print information if the user is authenticated by said user-authentication means.

2. An image processing system according to claim 1, wherein the table is held in a memory within said image processing apparatus.

3. An image processing system according to claim 1, wherein the table is held on an external medium connected to said image processing apparatus.

4. A storage medium storing a program constituting one of said means according to any one of claims 1-6, so as to be readable from a computer.

6. An image processing apparatus according to claim 4, wherein the table is held in a memory within said image processing apparatus.

7. An image processing apparatus according to claim 4, wherein the table is held on an external medium connected to said image processing apparatus.

8. An image processing apparatus according to any one of claims 4-6, wherein the voice feature stored in the table has been encrypted, and said voice-feature specification means comprises a determination means for determining the voice feature corresponding to the user identifier by decoding the encrypted voice feature.

5. An image processing apparatus for outputting print information by receiving the print information having a user identifier added thereto transferred from an electronic apparatus, said image processing apparatus comprising:

voice-feature specification means for specifying a voice feature based on the user identifier added to the print information by referring to a table for storing the voice feature in correspondence with the user identifier;

voice-feature extraction means for extracting a voice feature from a voice input from the user;

user-authentication means for authenticating the user by comparing the voice feature specified by said voice-feature specification means with the voice feature extracted by said voice-feature extraction means; and

print-information output means for starting output of the print information if the user is authenticated by said user-authentication means.

9. An image processing method for use in a system for forming an image on a medium based on print information transferred from an electronic apparatus to an image processing apparatus, said method comprising steps performed by the electronic apparatus, comprising:

an information addition step, of adding a user identifier to the print information; and

a transfer step, of transferring the print information having the user identifier added thereto to the image processing apparatus; and

said method also comprising steps performed by the image processing apparatus, comprising;

a voice-feature specification step, of specifying a voice feature based on the user identifier added to the print information by referring to a table for storing the voice feature in correspondence with the user identifier;

a voice-feature extraction step, of extracting a voice feature from a voice input from the user;

a user-authentication step, of authenticating the user by comparing the voice feature specified in said voice-feature specification step with the voice feature extracted in said voice-feature extraction step; and

a print-information output step, of starting output of the print information if the user is authenticated in said user-authentication step.

10. An image processing method according to claim 9, wherein the table is held in a memory within the image processing apparatus.

11. An image processing method according to claim 9, wherein the table is held on an external medium connected to said image processing apparatus.

12. A storage medium storing a program for executing one of said steps according to any one of claims 9-11, so as to be readable from a computer.

13. A program for executing one of said steps according to any one of claims 9-11.
