Description

  The present invention relates to a karaoke apparatus having a user authentication function based on music reproduced and output from a music reproducing apparatus.

  In recent years, a user of a music playback device is inputted by inputting a music played back and output from a music playback device (mobile terminal) and determining whether the music is a registered user (a music corresponding to ticket information). An authentication device for authenticating the above has been proposed (see Patent Document 1).

Japanese Patent No. 4501953

  Here, as an authentication device, for example, a karaoke device or the like, a parameter (for example, a pitch key value for setting a pitch (hereinafter referred to as a key) or a tempo value for setting a playback speed (hereinafter referred to as a pitch) for each piece of music to be played back and output. (Tempo) etc.) can be implemented in a device provided with a function for changing the setting. When a parameter of a music associated with a registered user is changed based on this function, the music reproducing device Even though the music corresponding to the registered user is reproduced and output from this, it is determined that this music is not the music corresponding to the registered user as a result of being compared with the same music with the parameter changed. As a result, the user may not be correctly authenticated.

  The present invention has been made in order to solve such a problem, and the purpose of the present invention is that even if a parameter of a music corresponding to a certain registered user is changed, the user of the user based on that music is changed. It is to be able to authenticate correctly.

  In order to solve the above-described problem, the first configuration (claim 1) is a parameter for reproducing and outputting the music for each of the music indicated by the music data stored in the storage unit in response to an external command. Parameter changing means capable of changing the music, music reproducing means for reproducing and outputting the music indicated by the music data stored in the storage unit from the speaker according to the parameters changed by the parameter changing means for the music, and predetermined music The music input means for inputting the music reproduced and output from the playback device, and the music input by the music input means are indicated by the music data associated with the user among the music data stored in the storage unit. The user who is associated with the music data indicating the music whose similarity is equal to or higher than a predetermined threshold compared with each music is input Corresponding to the user among the music indicated by the music data stored in the storage unit prior to the comparison by the music authentication means and the music authentication means for authenticating that the user is the user of the music playback device that has played and output the music Parameter matching means for matching the parameters of each music piece with the music inputted by the music input means by returning the parameters changed by the parameter changing means to the original for each piece of music indicated by the attached music data And.

  The music authentication means authenticates the user by comparing the music input by the music input means with the music whose parameters are matched by the parameter matching means.

  If it is a karaoke apparatus which concerns on this structure, even if the parameter of the music shown by the music data matched with a certain user has been changed, prior to user authentication based on the music reproduced and output from the music playback apparatus The parameters of each piece of music indicated by the music data are restored. As a result, when the music corresponding to the user is reproduced and output from the music playback device, this music is compared with the same music in which the parameters are not changed, so that the user can be authenticated correctly. become.

  In this configuration, “parameters for reproducing and outputting music” changed on the music reproducing device side include, for example, the key of the music to be reproduced and output (degree of pitch based on the original music), tempo ( It is a parameter such as length in the time direction), voice level, and bandwidth.

  In the above configuration, the user authentication is performed by comparing the component waveforms such as frequency and level in the music reproduced and output from the music reproducing device with each of the component waveforms in the music indicated by the music data associated with the user. This should be done in

  Specifically, the former song may be stored as song data, and the component waveform in this song may be compared with each component waveform in the latter song, or in time with the timing at which the former song is input. The component waveform in the music piece may be compared with each of the component waveforms in the latter music piece in real time.

  Here, when the component waveform in this music is compared with each component waveform in the latter music in real time in accordance with the timing when the former music is input, each of the latter music is reproduced and output on the karaoke apparatus side. However, in this case, each of the latter pieces of music is output at the same time as the music by the music reproducing device, and this may give a sense of discomfort to the user of the music reproducing device.

  Therefore, in such a case, it is desirable not to output each of the latter pieces of music on the karaoke device side. As a configuration for that purpose, the above configuration is as shown in a second configuration (Claim 2) shown below. It is good to.

  In the second configuration, when the music is input by the music input means, the music reproducing means reproduces the music whose parameters are matched by the parameter matching means without outputting them from a speaker. The authenticating means compares the music input by the music input means with each of the music reproduced with the parameters being matched by the music reproducing means, and the music having a similarity equal to or higher than a predetermined threshold value. Is authenticated as a user of the music playback device that plays back and outputs the input music.

  With this configuration, when the music reproduced and output from the music playback device is compared with each of the music indicated by the music data associated with the user, each of the latter music is output simultaneously with the music by the music playback device. Therefore, it is possible to prevent the user of the music playback device from feeling uncomfortable.

  In order to solve the above-mentioned problem, it is also conceivable to use a program that causes each component to perform the same procedure as each means in each component, and each component that executes this program has each component described above. The same actions and effects can be obtained.

  This program consists of an ordered sequence of instructions suitable for processing by a computer system, and is provided to a karaoke device, a user who uses this, etc. via various recording media and communication lines. do it.

  In order to solve the above problem, a third configuration (claim 3) is an authentication system including a music playback device capable of playing back music and a karaoke device having a user authentication function of the music playback device.

  The music playback device includes music output means for playing back and outputting the music indicated by the music data from a speaker based on the music data stored in the storage unit included in the music playback device.

  On the other hand, the karaoke apparatus receives a command from the outside, and for each piece of music indicated by the music data stored in the storage unit, parameter changing means capable of changing a parameter when the music is reproduced and output, and Music reproduction means for reproducing and outputting the music indicated by the music data stored in the storage unit from the speaker according to the parameter changed by the parameter changing means, and the music reproduced and output from the predetermined music reproduction device Comparing the music input by the music input means and the music input by the music input means with each of the music indicated by the music data associated with the user among the music data stored in the storage unit. The user associated with the music data indicating the music whose similarity is equal to or greater than the value reproduces and outputs the input music The music authentication means for authenticating as a user of the music reproducing device, and the music data associated with the user among the music indicated by the music data stored in the storage unit prior to the comparison by the music authentication means. Parameter matching means for matching each parameter of the music with the music input by the music input means by returning the parameter changed by the parameter changing means to the original for each of the displayed music . Then, the user authentication is performed by the music authentication means by comparing the music input by the music input means with the music whose parameters are matched by the parameter matching means.

(1) Overall Configuration The authentication system 1 is a system for authenticating a user. As shown in FIG. 1, a terminal device 2 owned by the user and a karaoke device 4 in which a user authentication function by the terminal device 2 is implemented. And a management device 6 that can communicate with each of the terminal device 2 and the karaoke device 4.

  The terminal device 2 includes a control unit 21 incorporating a CPU, ROM, RAM, EEPROM, and the like, a storage unit 23 that stores processing results by the control unit 21, a user interface (U / I) 25 including a monitor and an operation panel, The mobile phone terminal includes a communication unit 27 that controls communication (wireless communication) via the network 100, an audio processing unit 29 that controls input of audio from the microphone 31 and output of audio from the speaker 33, and the like.

The terminal device 2 has a music playback function that plays back and outputs the music indicated by the music data stored in the storage unit 23 from the speaker 33 via the audio processing unit 29.
The karaoke apparatus 4 includes a control unit 41 composed of a CPU, ROM, RAM, etc., a storage unit 43 that stores processing results by the control unit 41, a user interface (U / I) 45 composed of a keyboard, etc., and communication via the network 100. A communication unit 47 for controlling the sound, a sound processing unit 49 for controlling sound input from the microphone 51 and sound output from the speaker 53, and the like.

  In addition to the user authentication function described above, the karaoke apparatus 4 has a music playback function for playing back and outputting music indicated by the music data stored in the storage unit 43 from the speaker 53, and parameters of music played back and output by this function. It also has a parameter change function for changing settings.

  The management device 6 includes a control unit 61 including a CPU, a ROM, and a RAM, a storage unit 63 that stores a processing result by the control unit 61, a user interface (U / I) 65 including a keyboard, and communication via the network 100. It is a server provided with the communication part 67 etc. which control.

The operation of the authentication system 1 having such a configuration will be described with reference to FIG.
In this authentication system 1, first, when the terminal device 2 makes a registration request to the management device 6 (a), the management device 6 selects and registers music data corresponding to the identification information accompanying the registration request (b) The music data is transmitted to the terminal device 2 (c), and the music data and the identification information are transmitted to the karaoke device 4 (d). The terminal device 2 stores this music data in the storage unit 23 (e), and the karaoke apparatus 4 stores the music data in the storage unit 43 in association with the identification information (f). In this way, user registration for the karaoke apparatus 4 is performed, and preparation for user authentication is completed.

  As described above, the karaoke apparatus 4 has a parameter changing function, and receives an operation for specifying a music piece and changing the parameter (an operation with a command to change the parameter and its change amount). Then, the setting of the corresponding parameter of the designated music is changed based on the parameter changing function (g).

  In the present embodiment, each piece of music data stored in the storage unit 43 is associated with change information (initial value: change amount 0) indicating a parameter change value of the music indicated by the music data. However, it is updated to the change amount according to the change content commanded by the operation. Note that one or more of parameters (frequency distribution), tempo (length in the time direction), audio level, band, and the like are selectively used as parameters.

  After that, when authenticating the user with the karaoke device 4 (in this embodiment, authentication for reproducing and outputting a specific music piece), the music reproducing function of the terminal device 2 owned by the user first stores it in the storage unit 23. The music (authenticated music) indicated by the stored music data is played back and input to the karaoke apparatus 4 (h).

  In this way, the karaoke apparatus 4 that has input the authentication music reproduced and output by the terminal device 2 has the parameters changed as described above among the music (target music) indicated by the music data stored in the storage unit 43. The parameter change amount is returned to the initial value 0 and matched with the authenticated music, and each target music is played back (i).

  Then, the karaoke apparatus 4 compares the authentication music piece with the target music piece, and as a result, the user corresponding to the music piece data indicating the target music piece (including an approximation of a predetermined ratio or more) that matches the authentication music piece. Authentication is performed as a user of the terminal device 2 (j).

  Thus, after authenticating the user, the karaoke device 4 again changes the parameter to the same setting as previously changed for each piece of music in which the parameter is returned to the initial value as described above. (K).

Thereafter, the karaoke apparatus 4 performs reproduction output of a predetermined music piece when the user authentication is correctly performed (l).
(2) Procedure until preparation of user authentication Below, the procedure until the preparation of user authentication is prepared between the terminal device 2 and the karaoke apparatus 4 is demonstrated based on the process of each apparatus shown in FIG.
(2-1) Operation Acceptance Processing by Terminal Device 2 First, the procedure of the operation acceptance processing executed by the control unit 21 of the terminal device 2 will be described. This operation reception process is performed every time an operation is received via the operation panel of the user interface 25.

  When the operation acceptance process is started, first, it is checked whether or not the accepted operation is a “user registration operation” (s110). The “user registration operation” is an operation for requesting the user registration to the management apparatus 6, and predetermined operation contents are assigned in advance.

  If it is determined in s110 that the “user registration operation” has been received (s110: YES), a registration request with identification information assigned to the user of the terminal device 2 is transmitted to the management device 6 (s120). In the present embodiment, the identification information is stored in advance in the EEPROM or the storage unit 23 of the control unit 23, but may be input by the user each time.

The management apparatus 6 that has received the registration request transmits music data associated with the identification information on the management apparatus 6 side.
Thus, when the music data is received from the management device 6 after the registration request is transmitted, the music data is stored in the storage unit 23 as indicating the authentication music for authentication (s130), and a message to that effect is sent to the user. After being displayed on the monitor of the interface 25 (s140), the operation acceptance process is terminated.

If it is determined that the accepted operation is not a “user registration operation” (s110: NO), a process corresponding to the operation (other process) is performed (s170), and then the operation accepting process ends. To do. Note that part of the processing performed here is authentication processing described later.
(2-2) User Registration Process by Management Device 6 Next, a user registration process procedure executed by the control unit 61 of the management device 6 will be described. This user registration process is performed every time a registration request is received from the terminal device 2.

When the user registration process is started, first, music data corresponding to the identification information accompanying the registration request is selected from a plurality of music data prepared in advance (s210).
Here, it is configured to randomly select from a plurality of music data stored in advance in the storage unit 63 according to the identification information, but the user attributes (for example, gender, age, affiliation) are determined from the identification information. Etc.) may be selected so that music data indicating the music that matches the attribute may be selected.

  Next, the identification information associated with the registration requirement and the music data selected in s210 are registered in the database stored in the storage unit 63 (s220). Here, in addition to the music data (address) and identification information, a record in which the music number of the music indicated by the music data, the initial value of the parameter in this music, and the like are set is registered in the database.

  Next, the music data selected in s210 is transmitted to the terminal device 2 that is the transmission source of the registration request (s230). This music data is received by the terminal device 2 in s130 of the operation reception process.

Next, the music data selected in s210 and the identification information accompanying the registration request are transmitted to the karaoke apparatus 4 (s240). In the karaoke apparatus 4 that has received the music data and the identification information, the identification information and the music data are associated with each other and stored in the storage unit 43 in the music registration process that is started upon reception of the music data (s310). ).
(2-3) Setting Change Process by Karaoke Apparatus 4 Subsequently, a processing procedure of the setting change process executed by the control unit 43 of the karaoke apparatus 4 will be described with reference to FIG. This setting change process starts when a setting change operation is performed. The “setting change operation” is an operation for designating a song for which the parameter is changed for the music indicated by any of the music data stored in the storage unit 43 and for specifying the amount of parameter change. Predetermined operation details are assigned in advance.

When this setting change process is started, first, music data indicating the music designated by the setting change operation is read from the storage unit 43 (s320).
Then, after the parameter of the music indicated by the music data read in s320 is changed (s330), the setting change process is terminated. In s330, the change information corresponding to the music data is updated to the change amount corresponding to the change content designated by the setting change operation.
(3) Procedure for Performing User Authentication A procedure for performing user authentication between the terminal device 2 and the karaoke device 4 will be described below based on the processing of each device shown in FIG.
(3-1) Authentication process by terminal device 2 First, the process procedure of the authentication process executed by the control unit 21 of the terminal device 2 will be described. This authentication process is performed every time an operation for starting user authentication is accepted via the operation panel of the user interface 25.

When this process to be authenticated is started, first, the music data stored in the storage unit 23 is read as indicating the authenticated music in the operation receiving process (s130) (s450).
Next, the authentication music indicated by the music data read in s450 is reproduced and output from the speaker 33 (s460). (Figure 5, missing s460)
The authentication music reproduced and output in this way is input from the microphone 51 of the karaoke device 4, and the authentication result is transmitted from the karaoke device 4 after authentication based on the authentication music is performed.

After the authentication music is reproduced and output in the above s460, it enters a standby state until the authentication result from the karaoke apparatus 4 is received (s470: NO). When the authentication result is received (s470: YES), the authentication result is The message is displayed on the monitor of the user interface 25 (s480), and the process to be authenticated ends.
(3-2) User Authentication Process of Karaoke Apparatus 4 Subsequently, a process procedure of a user authentication process executed by the control unit 41 of the karaoke apparatus 4 will be described. This user authentication process is repeatedly executed after an operation for starting user authentication is performed via the operation panel of the user interface 45.

  When the user authentication process is started, the process first waits until voice input at a predetermined level or higher is started from the microphone 51 (s510: NO). Thereafter, when voice input is started (s510: YES). ), Audio output through the speaker 53 is interrupted (s520). Here, the audio output is interrupted by not performing the output from the speaker 53 via the audio processing unit 49.

  Next, by returning the parameter change amount in the target music indicated by the music data stored in the storage unit 43 in the music registration process to the initial value 0, the parameters in the target music are matched with the authentication music (s530). . Here, the change information is returned to the initial value 0 only for the music data associated with the change information indicating a value other than the initial value 0 among the music data stored in the storage unit 43. The parameters of the authenticated music and all the target music are matched (matched with the change amount “0”).

  Next, each of the target songs indicated by the song data stored in the storage unit 43 is played, and each of the target songs played in this way is compared with the input authentication song (s540). Here, reproduction of all target music is started, and thereafter, waveform components such as frequency and level in each target music are compared with component waveforms in the authentication music.

  The comparison here may be performed over the entire period of the authentication music piece and the target music piece, or may be performed over only a part of each period. In addition, it is desirable to reproduce and compare the target music from the time position taking into account the time lag so far, or to compare with the authentication music based on the shifted time position.

In this way, as a result of the comparison in s540, it is checked whether or not there is a target music that matches the authentication music (including an approximation of a predetermined ratio or more) in the target music (s550).
If it is determined in s550 that there is a matching target song (s550: YES), the user of the terminal device 2 has been correctly recognized as the user of the identification information corresponding to the song data indicating the target song. The authentication result to the effect is transmitted to the terminal device 2 (s560).

  When the authentication result is transmitted in this way, after the parameter of the target music matched with the authentication music in s530 is changed to the same setting as previously changed (s562), in s520 The interrupted voice output is resumed (s570).

  On the other hand, when it is determined in s550 that there is no matching target music (s550: NO), an authentication result indicating that the user cannot be correctly authenticated is transmitted to the terminal device 2 (s580).

  When the authentication result is transmitted in this way, after the parameter of the target music matched with the authentication music in s530 is changed to the same setting as previously changed (s582), in s520 The interrupted voice output is resumed (s590).

These authentication results are received by the terminal device 2 in s470 of the process to be authenticated. In the terminal device 2 that has received the authentication results, the results are displayed on the monitor.
Thus, after the authentication result is transmitted and the voice output is resumed, the reproduction of the corresponding music is started (s600) and the process returns to s510 only when the authentication is correctly performed in s560. . On the other hand, if the authentication cannot be correctly performed in s580, the process returns to s510 without reproducing and outputting the music.

In the present embodiment, the music reproduced and output in s600 is the target music determined to match the authenticated music in s550, but the specific music associated with the authenticated user or the karaoke device 4 It may be a specific music according to the environment such as time and place. The music to be played back is reproduced and output based on the changed parameter if the parameter has been changed, and is reproduced and output based on the initial value parameter if the parameter has not been changed. .
(4) Operation and Effect In the karaoke device 4 in the authentication system 1, even if the parameter of the music indicated by the music data associated with a certain user has been changed (s330 in FIG. 4), the terminal device 2 Prior to user authentication based on the music reproduced and output from, the parameter of each music indicated by the music data associated with the user is returned to the change amount “0” (s530 in FIG. 5). As a result, when the music corresponding to the user is reproduced and output from the terminal device 2, the music is compared with the same music in which the parameters are not changed, so that the user can be authenticated correctly. become.

Moreover, in the said embodiment, when comparing the music reproduced | regenerated and output from the terminal device 2 with each object music, when each audio | voice output is interrupted (s520 of FIG. 5), each object music is the authentication music by the terminal device 2. At the same time, it is not output. Thereby, it is possible to prevent the user of the terminal device 2 from feeling uncomfortable due to the target music and the authentication music being reproduced and output at the same time.
(5) Modifications Embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say.

  For example, in the above-described embodiment, the case where the karaoke device 4 and the management device 6 are configured as separate devices that can communicate with each other is illustrated, but these devices may be configured as an integrated device.

In the above embodiment, the user is authenticated by comparing the component waveform in this music with each waveform in the target music in real time in accordance with the input timing of the authentication music. However, when authenticating the user, the authentication music piece may be stored as music data, and the component waveform in the music piece may be compared with each component waveform in the target music piece afterwards.
