Description

  The present invention relates to an authentication system including a music playback device that can play back music and an authentication device that authenticates a user of the music playback device.

  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 system has been proposed (see Patent Document 1).

Japanese Patent No. 4501953

However, when the music playback device is used in the authentication system, if the music as the authentication data is other than the user's favorite music, the user can play the music as authentication data from the music playback device to the authentication device. Every time you play, you will hear a song you don't like.
In other words, there is a high risk that the authentication operation using music will cause pain to the user.

  The present invention has been made to solve such a problem, and an object of the present invention is to reduce the possibility that a piece of music as authentication data becomes a piece of music that the user does not like.

  In order to solve the above problems, a first configuration (claim 1) includes a music playback device capable of playing back music, an authentication device for authenticating a user of the music playback device, a management device for storing a music data group, An authentication system consisting of

First, the music reproducing device receives a user operation, and transmits the identification information of the user to the management device, and the identification information is transmitted by the reproducing side transmission unit, and then the identification information is transmitted. a reproducing side storage means for storing the re Namagawa storage unit a plurality of music data transmitted from the management apparatus receiving the information, certain music (identified from a plurality of music data stored in the reproducing-side storage unit Music output means for selecting and playing back music).

  The management device stores the management-side communication means for receiving the identification information from the music reproduction device, the music storage means for storing a music data group, and the music storage means when receiving the identification information. The music selection means for selecting and reading out a plurality of types of music data from the music data group to be recorded, the identification information and the read out the plurality of types of music data are associated with each other, stored in a management-side storage unit, and the authentication device Management-side transmission means for transmitting to the network.

On the other hand, the authentication device, when receiving the identification information and the plurality of types of music data from the management device, an authentication side storage means for storing in the authentication side storage unit, and a music input means for inputting music from outside When the music is input to the music input means, the music data group stored in the authentication-side storage means is sequentially read out (target music) and compared with the input music, and matches the input music Music authentication means for specifying identification information associated with the music data of the music to be played, wherein the music authentication means stores the specific music in the music input by the music input means in the authentication-side storage unit. When the specific music in the input music is included in the music of the plurality of music data as compared with the plurality of music data stored, it is associated with the target music Identification information of the user, the authentication certain music as a user of the reproduction output by the music reproduction device is performed.

  In this way, in the above configuration, a plurality of types of music data that may be a user's preference, which is a specific music related to authentication on the authentication device side, based on a request from the user's music playback device side, On the management device side, the music playback device associated with the user of the music playback device is stored in advance in the music playback device playback side storage unit and the authentication side storage unit of the authentication device. What is necessary is just to suppose that a user selects music data which is liking and reproduces and outputs from the music reproduction apparatus side.

  With this configuration, after the management apparatus side associates the identification information with the specific music based on the identification information transmitted from the music playback device, the music data and the identification information indicating the specific music are stored in the authentication device. Transmitted and stored. As a result, the authentication apparatus can perform authentication based on the comparison between the specific music and the target music. Since authentication based on the comparison of both music pieces is performed, the user can play back and authenticate his / her favorite music piece from among a plurality of types of music data from the music playing device.

  In each of the above configurations, since the authentication device stores the user identification information and a plurality of types of music data in association with each other, when the number of users necessary for authentication increases, the number of music data to be stored (data capacity) Can be enormous.

  Among these, after the authentication with the specific music according to the user's intention, the music data capacity of the user required for the authentication is reduced, so that the degree of the increase in the music data to be stored is reduced even if the number of other users to be authenticated increases. For this purpose, for example, the above-described configuration may be a second configuration (claim 2) described below.

  The music authentication means, when the authentication is performed, out of a plurality of music data associated with the identification information that has been authenticated, music data other than music data including a specific music, Delete from the authentication storage means.

If it is this composition, after user's authentication, music data required for the authentication of the same user can be reduced by deleting music data that was not used for the user's authentication,
Since the music data of the specific music used for authentication is not deleted, it is preferable because the user can repeatedly authenticate with the favorite specific music used for authentication.

  In each of the above configurations, when the number of users to be authenticated continues to increase, the music data to be associated with the identification information of other users is insufficient from the music data group stored in the management apparatus. For this reason, even if another user issues a registration request to the management apparatus, there is a possibility that sufficient music data types are not provided, and the user's favorite music cannot be reproduced (authenticated).

  In order to prevent the increase in the number of types of music data stored in the management device and the possibility that other users cannot authenticate with their favorite music when the number of users to be authenticated increases. For example, the above configuration may be a third configuration (claim 3) described below.

When the authentication is performed, the music authentication means of the third configuration transmits information for identifying music data including the specific music to the management device, and the management-side transmission means transmits the specific music When the information for identifying the music data including the specific music is received from the music data group stored in the management-side storage unit when the information for identifying the music data including the specific music is included. Music data, identification information associated with music data including the specific music, and a plurality of music data associated with the identification information are extracted, and a plurality of music data associated with the identification information is extracted. The music data other than the music data including the specific music is canceled from the identification information and the association with the identification information.

  If it is this structure, when this user authentication is performed by specific music, the management apparatus will authenticate other types of music data not used for authentication (which is not the user's preference) to other users. If the number of users to be authenticated increases, the number of types of music data stored in the management device may be insufficient, and other users may not be able to authenticate with their favorite music Etc. are preferable because they do not increase.

Embodiments of the present invention will be described below with reference to the drawings.
(1) Overall Configuration The authentication system 1 is a system for authenticating a user. As shown in FIG. 1, the terminal device 2 owned by the user, the authentication device 4 for authenticating the user of the terminal device 2, and the terminal It comprises a management device 6 that can communicate with the device 2 and the authentication device 4.

  The terminal device 2 includes a control unit 21 having a built-in CPU, ROM, RAM, etc., a storage unit 23 for storing processing results by the control unit 21, a user interface (U / I) 25 including a monitor and an operation panel, the Internet, A mobile unit including a communication unit 27 that controls communication (wireless communication) via the network 100 such as a mobile phone communication network, a voice processing unit 29 that controls voice input from the microphone 31 and voice output from the speaker 33, and the like. It is a telephone terminal.

  Note that the terminal device 2 has a music playback function in which a user selects music indicated by music data stored in the storage unit 23 and plays back and outputs from the speaker 33 via the audio processing unit 29.

  The authentication device 4 includes a control unit 41 including a CPU, a ROM, and a RAM, a storage unit 43 that stores processing results by the control unit 41, a user interface (U / I) 45 including a keyboard, 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 the present invention, the authentication device 4 is implemented as a partial function of the karaoke device.

  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 notifies its own identification information (telephone number, ID, etc.) via a communication line and makes a registration request to the management device 6 (a), the management device 6 After selecting a plurality of types of music data according to the identification information accompanying the registration request and registering the identification information and the plurality of types of music data in association with each other (b), as a registration response to the registration request from the terminal device 2 The music data is transmitted to the terminal device 2 (c), and the music data associated with the identification information is also transmitted to the authentication device 4 (d).

  The identification information used here may be information that can be specified by the terminal device 2 via the network 100, and may be a telephone number, a user ID, or the like.

  The plural types of music data may be a music data group of different arrangements (for example, rock tone, enka tone, etc.) of the same music name, a music data group of different music, and the like.

  The music data group is a set of music data, and a plurality of types of music data may be incorporated in a single file. In this case, each music data and the identification number are associated in one file. Alternatively, one piece of music data may be used as one file, and management data (not shown) for individually managing a plurality of files may be prepared separately and associated with each other. FIGS. 2C and 2D show a case where each file is sent individually.

  While the terminal device 2 stores the plurality of types of music data in the storage unit 23 (e), the authentication device 4 stores the identification information and the plurality of types of music data associated with the identification information. (F). Thus, preparation for user authentication is completed between the terminal device 2 and the authentication device 4.

  As described above, the terminal device 2 has a music playback function in which the user selects and plays back music data (g). This operation is an operation in which the user selects one piece of music data from a plurality of pieces of music data and instructs reproduction as a music piece.

  When authenticating the user of the terminal device 2 on the authentication device 4 side, the music (specific music) indicated by the music data previously stored in the storage unit 23 is reproduced and output by the music reproduction function of the terminal device 2. This is input to the authentication device 4 (h).

  When the music signal is input from the microphone 51, the authentication device 4 records the music signal for a predetermined time, reads the music data from the recorded music signal (target music) storage unit 43, reproduces the music data as the target music, and plays the microphone. The pitch with the music signal (specific music) input from 51 is compared.

  Then, as a result of the comparison between the specific music and the target music, the authentication device 4 has authentication data corresponding to the music data indicating the target music that matches the specific music (including an approximation of a predetermined ratio or more). Is authenticated as a user of the terminal device 2 (i), and the music number and authentication information of the specific music used for the authentication are notified to the management device 6 (j).

  Then, with respect to music data other than the specific music used for authentication among the plurality of music data associated with the authentication information, the association with the authentication information is canceled or deleted (k). By doing so, the authentication device 4 does not authenticate other than the specific music from the next authentication information authentication.

  Further, as a process for canceling the association with the authentication information, even if the music data other than the specific music used for the authentication is deleted, the authentication device 4 is deleted (the association is canceled) from the next authentication. Since the music data cannot be compared, authentication is not performed for other than specific music.

  When the management device 6 is notified of the authentication information and the music number of the specific music from the authentication device 4, the music data other than the notified music number is obtained from the association between the currently stored authentication information and a plurality of music data. The association with the authentication information is canceled (l).

If the music data other than the notified music number (music data with which the association with the authentication information is canceled) is reused for other users, the deletion is not performed.
By doing so, when there is a registration request from another user, the management device 6 can reuse the music data other than the specific music for association with the authentication information of the other user.

  Next, the management device 6 confirms that the association with the authentication information is canceled by the specific music for the terminal device 2 (the authentication device 4 has completed authentication), and the music number of the specific music (the name of the music name). (M)

  The terminal device 2 can know that the authentication with the authentication device 4 can be performed by the specific music by notifying the specific music number from the management device 6.

  Then, the terminal device 2 selectively reproduces the music data associated with the identification information, and the user does not accidentally reproduce the uncomfortable music data other than the music data that has been authenticated. As described above, the following processing may be performed.

  When a specific song name is notified from the management device 6, among a plurality of types of music data stored in the storage unit 23, a plurality of types of music data stored as a response to the registration request (a) to which the specific music belongs (see FIG. 4), music data other than the specific music is deleted or not reproduced (n).

(2) Procedure until Preparation for User Authentication A procedure until preparation for user authentication is prepared between the terminal device 2 and the management device 6 will be described below based on processing of each device 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 23 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 this 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.
Specifically, an operation such as “applying a karaoke reservation ticket” can be considered.

  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 a telephone number, a MAC address, an IP address, or the like stored in advance in the EEPROM of the control unit 23 or the storage unit 23. However, even if the user inputs a user ID, a name, or the like each time. Good.

  The management device 6 that has received this registration request transmits a music data group of a plurality of music data associated with the identification information.

Thus, when the music data group is received from the management device 6 after the registration request is transmitted, the music data group indicates a candidate to be a specific music for authentication for each music data group corresponding to one registration request. One group is formed and stored in the storage unit 23 (s130).
A group number that can be identified for each group is assigned to the group, and the group to which the music number belongs can be specified by searching the music number. (Fig. 4 (a))
Thereafter, after a message to that effect is displayed on the monitor of the user interface 25 (s140), the operation acceptance process is terminated.

  From the end of the reception process until the music is output to the authentication device 4 of the authentication process by the terminal device 2 to be described later, the user selects an arbitrary music from the music data group displayed on the monitor of the user interface 25. By reproducing and viewing, the music data that is least unpleasant for the user can be specified.

(2-2) User Registration Process by Management Device 6 Next, a user registration process procedure executed by the control unit 63 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 becomes a music data group selected from a plurality of types of music data prepared in advance (s210). The number of types selected is a quantity that is prepared in advance or less than the number of pieces of music data.

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 included in the identification information. , Genre, quantity, etc.) can also be selected, it is possible to select a song data group indicating a song that matches the attribute.
Specifically, the song data includes the type of song (genre, target age, etc.) in advance, and when the user requests registration, the terminal device 2 has the type and quantity desired by the user along with the identification information. When sent, the music data is selected according to the type and quantity and associated with the identification information, thereby forming a music data group corresponding to the identification information accompanying the registration request.

  Next, the identification information associated with the registration requirement when the registration request is made and the music data group selected in s210 are registered in the database stored in the storage unit 63 ( s220).

  Specifically, as shown in FIG. 4 (b), there are multiple registration requests from the same user in addition to music data (such as ringtone MIDI data and live audio data for viewing) and identification information for identifying the user. A record in which a creation number for distinguishing music data groups that have been associated differently with the same identification information and a correspondence set such as the music number of the music indicated by the music data is registered in the database. .

  In general, since a database has a data exclusive processing function, it is included in the registered record by registering it in the database as a record in which the identification information, the creation number, and the music data group are associated with each other. The music data is no longer used for associating with other authentication information, and the same music data is not associated with multiple registration requests by the same user or different authentication information.

  Next, the music data group selected in s210 is transmitted to the terminal device 2 that is the transmission source of the registration request (s230). This music data group 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 authentication device 4 (s240). Upon receiving the music data and the identification information, the authentication device 4 stores the identification information and the music data group in the storage unit 43 in a state where the identification information and the music data group are associated with each other in the music registration process started upon reception of the music data and the identification information ( s310).

(3) Procedure for Performing User Authentication Hereinafter, a procedure for performing user authentication among the terminal device 2, the authentication device 4, and the management device 6 will be described 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 23 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 authenticated process is started, it is first checked that the music to be played back is selected (s410). Here, the music data is selected from the music data group stored in the storage unit 23.

  The music data selected in s410 is read out from the storage unit 23 and reproduced for viewing (s420). If the user feels uncomfortable and does not meet the preference, a selection input operation is performed (s430: NO), viewing is repeated.

When the selected music data is not uncomfortable and a selection input operation that suits the taste is performed (s430: YES), the specific music used for authentication is determined.
Viewing by the user can be performed using an earphone (not shown) and the speaker 33, but the music signal is not input to the microphone 51 of the authentication device 4 until it is determined that the user does not feel uncomfortable.

  Next, the user reproduces and outputs the specific music confirmed in s430 from the speaker 33 (s440). The specific music reproduced and output in this way is input from the microphone 51 of the authentication device 4.

  After the specific music is reproduced and output in the above s430, the music data group other than the specific music that is not selected for the reproduction after the confirmation of s430 is deleted from the terminal device 2, and the authenticated process ends. For this reason, the music which the user did not use for authentication is not erroneously used in the next authentication.

(3-2) User Authentication Process of Authentication Device 4 Next, a process procedure of a user authentication process executed by the control unit 43 of the authentication device 4 will be described. This user authentication process is repeatedly executed after the authentication device 4 is activated.

  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, the voice input becomes higher than the predetermined level and voice input is performed. Is started (s510: YES), the audio output through the speaker 53 is interrupted or reduced (s520). Here, the audio output is interrupted by not performing the output from the speaker 53 via the audio processing unit 49.

If it is necessary to indicate to the user that voice input for authentication is performed, the voice output may be reduced or the voice level may be visualized by voice level display means (not shown) such as an indicator. Howling can be prevented by the above-described s520.

  Next, as for the sound whose input is started in the above s510, the sound input over the time length determined as the specific music is acquired as the specific music, and the specific music data indicating the specific music is stored in the storage unit 43. (S530).

  It should be noted that the “length of time determined as specific music” may be anything that can be specified as a predetermined constant value.

  Next, based on the specific music and the target music, the specific music and each of the target music are compared (s540). Specifically, one of the music data groups corresponding to all the authentication information stored in the storage unit 43 is read out and reproduced as the target music by the voice processing unit 49, and the pitches of the specific music and the target music are sequentially compared. . The comparison process may be a comparison of pitches made into sounds, or if the audio processing unit 49 has a DSP function, the specific music piece may be converted into digital data and the pitches may be compared with the music data group on, for example, PCM data. .

  As a result of the comparison in s540, it is checked whether or not the target music that matches the specific music (including the approximation of a predetermined ratio or more) exists 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. An authentication result to this effect is displayed (s560). As processing of the authentication result, processing other than display (for example, karaoke reserved song reproduction, billing processing, or operation instruction output to another device) may be executed.

  Next, when the authentication information is authenticated, the management apparatus 6 is notified of the music number of the target music that has been authenticated (s570). Since it was used for authentication information authentication, this target music coincides with the specific music associated with the authentication information reproduced and output by the terminal device 2 in s440.

  Next, the association with the authenticated authentication information is canceled for the music data other than the target music from the music data group associated with the authenticated authentication information (s590).

  By the processing of s570 and s590, the authentication device 4 can authenticate with music other than the authenticated target music in authentication by the user next time or later by eliminating the association with the authentication information except for the music that can be authenticated. Disappear. For this reason, the management apparatus 6 which received the notification of the authenticated music number can reuse music data other than the authenticated music data (music data not used for authentication) for authentication of other users.

  Next, the audio output interrupted in s520 is resumed (s595), the process returns to s510, and the subsequent processing is repeated.

  On the other hand, if it is determined that there is no matching target music (s550: NO), an authentication result indicating that the user cannot be correctly authenticated is displayed on a karaoke monitor (not shown) or the like (s580), and the process is interrupted. After the voice output is resumed (s595), the process returns to s510.

(3-3) Post-User Authentication Processing of Management Device 6 Next, a processing procedure of post-user authentication processing executed by the control unit 63 of the management device 6 will be described. This post-user authentication process is performed every time a notification of the target music number is received from the management device 4.

  When the post-authentication process is started, the reception input (s610) of the target music number from the authentication device 4 is checked (s620). When the target music number is input from the authentication device 4 (s620: YES), the identification information associated with the target music number is extracted from the record stored in the database of the storage unit 63, and is associated with the identification information. Among the recorded music data groups, a record that is no longer associated with the identification information is reconstructed and stored again for the music data group other than the target music number (s630).

  That is, since the music data group associated with the identification information after authentication is only the music data (target music) used for authentication, the management device 6 assigns the music data group not used for authentication to the other music data group. It can be reused for registration requests from users.

(4) Operation and Effect With the authentication system 1 having such a configuration, the user can select a favorite song from a plurality of song data and use it for authentication. (S420 to s440).

  Further, the music data other than the authenticated music data may be music that is unpleasant for a specific user but is not uncomfortable for other users and that the user wants to listen to. In other words, music data other than those authenticated by the user cannot be identified as music that is unpleasant to other users.

For this reason, as the number of users increases, if song data associated with identification information continues to increase in response to registration requests (identification information) from users, it is sufficient for registration requests (identification information) of other users. There is a high possibility that it becomes impossible to associate music data of various types and quantities (since it is an authentication system, music used for authentication is not shared between users). If sufficient types and quantities of song data are not associated with other users' registration requests, it is highly likely that the song data stored in the other user's terminal device 2 does not include a favorite song. Become. As a result, there is a high possibility that other users will have to authenticate using songs that they do not like.

  After the authentication, the authentication device 4 and the management device 6 cancel the association between the music data group that was not used for the authentication and the identification information (s570, s630). Thereby, since the management apparatus 4 can reuse other music data for the registration request of other users, there is a high possibility that other users can authenticate with music that other users do not feel uncomfortable. .

  Next, the management device 6 notifies the terminal device 42 of the music number of the music (target music) used for the authentication of the terminal device 2 (s640).

  The terminal device 2 compares the received song numbers s450 and s460 with each song number of the song data stored in the storage unit 23, specifies the group number to which the received song number belongs, and the song data belonging to the group number Among them, music data other than the received music number is deleted from the storage unit 23 or cannot be reproduced (s470).

  The music numbers received at s450 and s460 are the same as the target music numbers from s570 and s640, and the target music is the same as the music number of the specific music selected for authentication by the terminal device 2 from s440 and s530. To do.

  That is, the music data that can be reproduced from the terminal device 2 after the authentication is only the specific music used for the authentication. Thus, thereafter, the user can continue authentication with music that is not always unpleasant.

  Music data stored in the storage unit 23 for each registration request from the terminal device 2 is grouped, and music data other than music data that has not been reproduced by authentication according to the registration request cannot be reproduced. Therefore, even if the registration request is made more than once, the music data continuously stored for each registration request in the storage unit 23 will not be made unplayable except for the music data used for authentication by one authentication. By authenticating once for a registration request, other unpleasant music stored in response to another registration request is not disabled.

  Further, if the authentication is performed only once, the terminal device 2 may not associate the group number, and the management device 6 may not associate the creation number.
