Description

User authentication system, user authentication method and program

The present invention relates to a user authentication system, a user authentication method, and a program for identity verification required when a user accesses (logs in) various systems such as applications.

In recent years, the spread of the Internet has been remarkable, and companies of all types of business have established websites and provide various services through applications. Many of these websites provide services only to registered users, and in websites (applications) that can be used only by registered users, the registered users are the registered users. User authentication is performed to confirm whether or not there is.
This user authentication is generally performed using a user ID and a password. That is, when a user accesses the website, the user inputs a user ID for identifying the user and a password for confirming that the user is the user, and the entered user ID and password are registered. If the ID and password match, the website can be accessed (logged in).

In this case, the password set for identity verification in user authentication (including random numbers and unspecified character strings used for various types of authentication other than those set by the user) is composed of characters such as alphanumeric characters. Therefore, there is a high risk of theft and unauthorized use. For this reason, as a means for user authentication, voice print authentication, which is one of biometric authentication instead of password authentication or along with password authentication, has been proposed.
For example, Japanese Patent Laying-Open No. 2005-128307 (Patent Document 1) records voiceprint data of elements such as numbers and characters constituting a password for each registrant, and a password forming unit uses each element to generate a random password. The voice data forming means forms the voice data of the password using the voice print data of each element, and the voice data obtained by voice input of the password by the determination requester and the voice formed by the voice data forming means There is disclosed a voiceprint authentication system that collates data and determines that a determination requester is a registrant.
In Japanese Patent Application Laid-Open No. 2007-52496 (Patent Document 2), a password and a user's voiceprint data are registered in advance, and a password registered in advance by recognizing the spoken voice of the password input by the user by voice recognition. The user who determines whether the voiceprint data of the utterance voice of the password input by the user matches the user's voiceprint data registered in advance when the password authentication is successful. An authentication system is disclosed.
Furthermore, in Japanese Patent Laid-Open No. 2015-99470 (Patent Document 3), a user's voice print information is registered in advance in a server, and a character string generation unit of the server generates a certain character string and the user owns it. To the information portable terminal, and from the information portable terminal, the voice of a certain character string read out by the user is transmitted to the server, and the voice authentication of the character string received by the authentication unit of the server from the information portable terminal is An authentication system is disclosed in which user authentication is performed based on whether or not the voiceprint information of a user registered in advance matches.

By the way, when the voiceprint authentication system and the user authentication system of Patent Documents 1 to 3 are used as user authentication for accessing (logging in) an application or the like installed in a terminal device or the like, the registered user (person) Even if there is a voice print authentication, it cannot be accessed (logged in) unless it is successful.
However, in voiceprint authentication, the voiceprint data extracted from the voice data input by the same user is not always constant, and differs slightly depending on the speed of speech, inflection, timing of breathing, etc. There is a problem that even a user (person) does not succeed in voiceprint authentication and cannot access (login).
Further, in the user authentication system of Patent Document 2, since voice recognition and voiceprint recognition are performed from a user's speech using a preset password, if the user forgets the preset password, authentication is performed. There is also a problem that it is not done.

user authentication systems

1 and 20 will be described below.

[Outline of Authentication Processing by User Authentication System 1]
FIG. 5 is a flowchart showing an overview of authentication processing by the user authentication system 1, and FIG. 6 is an explanatory diagram showing an example of an initial screen displayed on the display unit 9 in the authentication processing by the user authentication system 1. In the figure, 200 is a display screen, 201 is a user ID input box, 202 is a password input box, 203 is a voice data button for selecting voice data input, and 204 is a password input button. This is a password button.
The outline of the authentication process in the user authentication system 1 will be specifically described below with reference to the drawings.

When the user authentication system 1 is activated, as shown in FIG. 6, the display screen 200 of the display unit 9 becomes an initial screen, and a box 201 for inputting a user ID, a box 202 for inputting a password, and voice data Button 203 and password button 204 are displayed.
At this time, “User ID” characters are displayed on the box 201, “Password” characters are displayed on the box 202, and “Voice login” characters are displayed on the voice data button 203. The password button 204 displays the characters “login with password”.
First, the user inputs a user ID, for example, a 5-digit number “00001” in the box 201 and inputs the user ID.
Next, the input selection unit 2 selects a login method for logging in by either voice data input or password input (S1). This is performed by the user's operation of pressing either the voice data button 203 or the password button 204.
When the user presses the voice data button 203, the input selection unit 2 selects a method for logging in by inputting voice data, and an authentication process using the voice data is executed (S2).
When the user presses the password button 204, the input selection unit 2 selects a method for logging in by inputting the password, and authentication processing using a password is executed (S3).

[Authentication process using voice data in the user authentication system 1]
FIG. 7 is a flowchart showing an authentication process using voice data (step S2 in FIG. 5) in the user authentication system 1. FIGS. 8 to 10 show examples of screens displayed on the display unit 9 in this authentication process. It is explanatory drawing shown.
The authentication process using voice data in the user authentication system 1 will be specifically described below with reference to the drawings.

When the user presses the voice data button 203 and the input selection unit 2 selects a method of logging in by inputting voice data, first, the character string generation unit 7 generates a random character string (S10).
Specifically, random alphanumeric characters, symbols, kana characters, and the like are generated. Here, a 5-digit random number is generated. The 5-digit random number (number) generated by the character string generation unit 7 is different every time.
Next, the random character string generated by the character string generation unit 7 is displayed on the display unit 9, and the voice data input request unit 4 requests the user to input voice (S11).
FIG. 8 shows a display screen 200 of the display unit 9 when the voice data input request unit 4 requests the user to input voice. In the figure, 211 is a user ID display section, 212 is a random number display section, 213 is a start button, and 214 is a sentence display section.
As shown in FIG. 8, on the display screen 200, the user ID “00001” input by the user is displayed on the upper user ID display unit 211, and the character string generation unit 7 generates the random number display unit 212 below it. A 5-digit random number is displayed together with the reading, a start button 213 is displayed below it, and a text “start button is displayed in the text display unit 214 below that indicates that the voice data input request unit 4 requests voice input from the user. Please tell me the number. "Is displayed.

Next, the user presses the start button 213 according to the text displayed on the text display unit 214, and the numbers “1”, “3”, “5”, “6”, “4” displayed on the random number display unit 212 are displayed. When the readings “1”, “san”, “go”, “roku”, “yon” are uttered by voice, the voice data input unit 3 inputs voice data issued by the user (S12).
FIG. 9 shows a display screen of the display unit 9 when the audio data input unit 3 is inputting audio data. In the figure, reference numeral 215 denotes a text display section, 216 denotes an end button, and 217 denotes a cancel button.
As shown in FIG. 9, in the text display section 215 in the middle of the display screen, the voice data input request section 4 requests the user to continue voice input, etc. “Please speak slowly. Finish after reading the number. "Please press." Is displayed, and an end button 216 and a cancel button 217 are displayed below it.
When the user finishes pronunciation of the number displayed on the random number display unit 212, the user presses the end button 216, thereby completing the voice input from the voice data input unit 3. The user presses the cancel button 217 when canceling the voice input.
The voice data storage unit 5 temporarily stores the user voice data input by the voice data input unit 3 as described above (S13).

Next, the character string recognizing unit of the voice recognizing unit 11 recognizes what character string the voice data (voice data of five digits) sent from the voice data storage unit 5 is composed of (S14). .
Next, the character string determination unit of the voice recognition unit 11 performs a character string recognized by the character string recognition unit and a random character string (5-digit random number (number)) generated by the character string generation unit 7 (this number is a character Sent from the column generation unit 7 to the speech recognition unit 11) is determined (S15).
If it is determined in step S15 that they match, the determination result (successful voice recognition) is sent to the voiceprint data generation unit 12, and the process proceeds to the next voiceprint authentication step (S16). The process proceeds to step S20 without performing voiceprint authentication.

If it is determined in step S15 that they match, the voice print data generation unit 12 generates voice print data from the voice data (voice data for a 5-digit random number (number)) sent from the voice data storage unit 5. (S16).
Next, the voiceprint data determination unit 14 transmits the voiceprint data generated by the voiceprint data generation unit 12 (this voiceprint data is sent from the voiceprint data generation unit 12 to the voiceprint data determination unit 14) and the user's voice stored in the voiceprint DB 15. The voiceprint data (voiceprint data specified by the user ID “00001”) is collated (S17).
Then, the voiceprint data determination unit 14 determines whether or not the difference in the voiceprint data to be collated is small and within a certain range (below the threshold), that is, whether or not the voiceprint data has been successfully authenticated (S18).
FIG. 10 shows a display screen of the display unit 9 from the voice recognition by the voice recognition unit 11 (S14) to the voiceprint data determination by the voiceprint data determination unit 14 (S18). In the figure, reference numeral 218 denotes a character display unit.
As shown in FIG. 10, from the step (S14) in which the speech recognition unit 11 recognizes what character string the speech data (speech data for a 5-digit random number (number)) consists of, the voiceprint data determination unit 14 Until the step of determining voiceprint data (S18), the character “authenticating” is displayed in the middle character display portion 218 of the display screen 200.

If the voiceprint data is successfully authenticated in the determination in step S18, the voiceprint data determination unit 14 outputs a voiceprint determination result indicating that the determination (authentication) of the voiceprint data is successful (authentication success) (S19). The voiceprint determination result is sent to the login unit 61 of the application system 60, and the process ends.
In this way, when the voiceprint data determination unit 14 sends the voiceprint determination result of the authentication success to the login unit 61 of the application system 60, the login unit 61 performs the login process and the application 62 is processed and controlled.
FIG. 11 is an explanatory diagram illustrating an example of a display screen of the display unit 9 after the login process is performed by the login unit 61 of the application system 60, in which 219 is a text display unit.
As shown in FIG. 11, a text such as “Welcome to AA Company” is displayed on the text display portion 219 of the display screen 200, the application 62 is processed and controlled, and the user uses the service provided by the application 62. be able to.

On the other hand, if the voiceprint data authentication fails in the determination in step S18, the voiceprint data determination unit 14 outputs a voiceprint determination result indicating that the voiceprint data determination (authentication) is unsuccessful (authentication unsuccessful) (S20). ), The output voiceprint determination result is sent to the display unit 9, and the display unit 9 displays that the determination result is unsuccessful, and ends the process.
If it is determined in step S15 that the audio data does not match, voice print authentication (S16 to S18) is not performed, and the same processing as in the case where authentication is determined to be unsuccessful is performed (S20). finish.
FIG. 12 is an explanatory view showing an example of the display screen of the display unit 9 on which the voice print determination result is unsuccessful, in which 220 is a text display unit, 221 is a start button, and 222 is a return. Button.
As shown in FIG. 12, a text “Authentication failed” is displayed in the text display unit 220 surrounded by a thick frame on the display screen 200, and voice print authentication fails for the user, and the application system 60. You will be informed that you could not log in.
In this case, the user can perform authentication processing by inputting voice data again by pressing the start button 221.
When the user presses the return button 222, the display screen 200 returns to the initial screen shown in FIG. 6, and the user starts the authentication process from the beginning, that is, uses a password instead of authentication (login) by voice input. Authentication (login) can be performed.

As described above, in the authentication process using voice data in the user authentication system 1, the random character string (5-digit random number) generated by the character string generator 7 is different every time. Even if the user's voice data is different every time, even if the user's voice data is recorded and used for authentication, the voice recognition is unsuccessful in step S15, and the result of the authentication unsuccessful decision is output, thereby preventing its unauthorized use. can do.
Even if the user is a legitimate user, the voiceprint data generated by the voiceprint data generation unit 12 from the input voice data is not always constant, and the voiceprint data authentication fails in the determination in step S18. In some cases, a sentence “Authentication failed” as shown in FIG. 12 is displayed.
Even in such a case, a legitimate user can perform the authentication process from the beginning and perform authentication (login) using a password, and the authentication process using a password, which will be described later, is performed. it can.

[Authentication process by password in the user authentication system 1]
FIG. 13 is a flowchart showing an authentication process using a password in the user authentication system 1 (step S3 in FIG. 5).

First, a user inputs and inputs a password (for example, 8 digits alphanumeric characters) registered in advance in the box 202, and the password input unit 6 thereby captures the input password (S30).
Next, the password determination unit 17 collates the password sent from the password input unit 6 with the password stored in the password storage unit 16 (password specified by the user ID “00001”) (S31). Are matched, that is, whether or not the password authentication is successful (S32).

If the password authentication is successful in the determination in step S32, the password determination unit 17 outputs a password determination result indicating that the password determination (authentication) is successful (authentication successful) (S33), and the output password determination result. Is sent to the login unit 61 of the application system 60, and the process ends.
As a result, similarly to the case where the voiceprint data is successfully authenticated, the login unit 61 of the application system 60 performs the login process, and the display unit 9 displays a display screen as shown in FIG. Processing and control are performed, and the user can use the service provided by the application 62.
On the other hand, if the password authentication fails in the determination in step S32, the password determination unit 17 outputs a password determination result indicating that the password determination (authentication) is unsuccessful (authentication unsuccessful) (S34). The output password determination result is sent to the display unit 9. The display unit 9 displays that the determination result is unsuccessful, and the process is terminated.
At this time, similarly to the case where the voiceprint data authentication is unsuccessful, the display screen 200 displays as shown in FIG. 12, and the user has failed to authenticate and could not log in to the application system 60. Be informed.
In this case, the user can perform the authentication process by inputting the password again by pressing the start button 221.
When the user presses the return button 222, the display screen 200 returns to the initial screen shown in FIG. 6, and the user starts authentication processing from the beginning, that is, by voice input instead of authentication (login) using a password. Authentication (login) can be performed.

[Voiceprint data registration process by the user authentication system 1]
FIG. 14 is a flowchart showing voiceprint data registration processing by the user authentication system 1, and FIGS. 15 to 18 show examples of screens displayed on the display unit 9 in voiceprint data registration processing by the user authentication system 1. It is explanatory drawing which showed.

When the user presses the password button 204, the input selection unit 22 selects a method of logging in by inputting the password, and authentication processing using a password is executed (S3 in FIG. 5).

[Authentication processing by voice data in the user authentication system 20]
FIG. 19 is a flowchart showing an authentication process using voice data in the user authentication system 20.
Hereinafter, the authentication process using voice data in the user authentication system 20 will be specifically described with reference to the drawings.
The processes in steps S50 to S53 shown in the flowchart of FIG. 19 are the same as the processes in steps S10 to S13 in the flowchart of FIG. 7 showing the authentication process using voice data performed by the user authentication system 1.
That is, in the terminal device 21, when the user presses the voice data button 203 displayed on the display screen 200 of the display unit 29 and the input selection unit 22 selects a method of logging in by inputting voice data, The column generation unit 27 generates a random character string (S50).
Next, the random character string generated by the character string generation unit 27 is displayed on the display unit 29, and the voice data input request unit 24 requests the user to input voice (S51).
At this time, a display screen 200 as shown in FIG.
Next, when the user utters voice according to the display on the display screen 200 of the display unit 29, the voice data input unit 23 inputs voice data issued by the user (S52).
At this time, the user presses the start button 213 according to the text displayed on the text display unit 214, and the numbers “1”, “3”, “5”, “6”, “4” displayed on the random number display unit 212. "Ichi", "san", "go", "Roku", "yon" are uttered by voice.
The voice data of the user input by the voice data input unit 23 in this way is temporarily stored by the voice data storage unit 25 (S53).
Next, the transmission unit 40 transmits the voice data stored in the voice data storage unit 25 and the random character string generated by the character string generation unit 27 to the server 30 side via the communication line 50 (S54). ).

Then, in the server 30, the receiving unit 42 receives the voice data and character string transmitted from the transmitting unit 40 (S55), and the data storage unit 44 temporarily stores the received voice data and character string (S56). .
Thereafter, the processes of steps S57 to S63 are performed. These processes are the same as the processes of steps S14 to S20 (the flowchart of FIG. 7) performed in the user authentication system 1.
That is, the character string recognizing unit of the voice recognizing unit 31 recognizes what character string the voice data (voice data of five digits) sent from the data storage unit 44 is composed of (S57).
Next, the character string determination unit of the speech recognition unit 31 performs a character string recognized by the character string recognition unit and a random character string (5-digit random number (number)) generated by the character string generation unit 7 (this number is data Sent from the storage unit 44 to the voice recognition unit 31) is determined (S58).
In step S58, if it is determined that they match, the determination result (successful speech recognition) is sent to the voiceprint data generation unit 32, and the process proceeds to the next voiceprint authentication step (S59). The process proceeds to step S63 without performing voiceprint authentication.

If it is determined in step S58 that they match, the voiceprint data generation unit 32 generates voiceprint data from the voice data (voice data of a 5-digit random number (number)) sent from the data storage unit 44. (S16).
Next, the voiceprint data determination unit 34 includes the voiceprint data generated by the voiceprint data generation unit 32 (this voiceprint data is sent from the voiceprint data generation unit 32 to the voiceprint data determination unit 34) and the user's voice stored in the voiceprint DB 35. The voiceprint data (voiceprint data specified by the user ID “00001”) is collated (S60).
Then, the voiceprint data determination unit 34 determines whether or not the difference in the voiceprint data to be compared is small and within a certain range (below the threshold), that is, whether or not the voiceprint data has been successfully authenticated (S61).
At this time, the terminal device from the step (S57) of recognizing what kind of character string the voice data is formed by the voice recognition unit 31 to the step (S61) in which the voiceprint data determination unit 34 determines the voiceprint data. In the display unit 29 of 21, the characters “authenticating” are displayed in the character display unit 218 in the middle of the display screen 210 as shown in FIG. 10.

If the voiceprint data has been successfully authenticated in the determination in step S61, the voiceprint data determination unit 34 outputs a voiceprint determination result indicating that the voiceprint data has been successfully determined (authenticated) (successful authentication) (S62). The voiceprint determination result is sent to the login unit 61 of the application system 60, and the process ends.
In this way, when the voiceprint data determination unit 34 sends the voiceprint determination result of the authentication success to the login unit 61 of the application system 60, the login unit 61 performs a login process to process / control the application 62, and the terminal As shown in FIG. 11, a text such as “Welcome to AA Company” is displayed on the text display unit 219 of the display screen 200 on the display unit 29 of the apparatus 21, and the user may use the service provided by the application 62. it can.
In this case, in the user authentication system 20, the application system 60 is connected to the terminal device 21 via the communication line 51 and the server 30, but the terminal device 21 and the application system 60 are directly connected via a communication line (not shown). You may make it connect.

On the other hand, if the voiceprint data authentication fails in the determination of step S61, the voiceprint data determination unit 34 outputs a voiceprint determination result indicating that the voiceprint data determination (authentication) is unsuccessful (authentication unsuccessful) (S63). ), The output voiceprint determination result is sent to the transmission unit 43, and is transmitted from the transmission unit 43 to the terminal device 21 side via the communication line 51.
In the terminal device 21, the reception unit 41 receives the determination result transmitted from the transmission unit 43 and sends it to the display unit 29. The display unit 29 displays that the determination result is unsuccessful and ends the processing. To do.
If it is determined in step S58 that the audio data does not match, voice print authentication (S59 to S61) is not performed, and the same processing as in the case where authentication is determined to be unsuccessful is performed (S63). finish.
At this time, the display unit 29 of the terminal device 21 displays the text “authentication failed” on the text display unit 220 surrounded by the thick frame of the display screen 200 as shown in FIG. On the other hand, it is notified that the authentication failed and the application system 60 could not be logged in.
In this case, the user can perform authentication processing by inputting voice data again by pressing the start button 221.
When the user presses the return button 222, the display screen 200 returns to the initial screen shown in FIG. 6, and the user starts the authentication process from the beginning, that is, uses a password instead of authentication (login) by voice input. Authentication (login) can be performed.

[Authentication process by password in the user authentication system 20]
FIG. 20 is a flowchart showing authentication processing using a password in the user authentication system 20.
The authentication process using a password in the user authentication system 20 will be specifically described below with reference to the drawings.
In the initial screen of the display unit 29 of the terminal device 21 (FIG. 6), after the user inputs the user ID, when the user presses the password button 204, the input selection unit 22 selects a method for logging in by inputting the password. To do. As a result, a password can be entered in the box 202 of the display screen 200.
