Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an authentication system, and more particularly to an authentication system and an authentication apparatus that perform authentication using sound information.
[0002]
[Prior art]
Conventionally, in the case of performing a management in which only pre-registered visitors are allowed to enter in a laboratory or event venue, for example, information such as the names of prospective visitors is registered in advance, and then the visitors are instituted in the laboratory. When entering the event venue, at the reception desk of the research institute or event venue, etc., let the attendee enter information such as name, and collate this information with information such as name registered in advance. There are ways to allow admission.
[0003]
In recent years, with the progress of the information society, an ID card capable of writing and reading information is issued, and attendee management is performed using this ID card.
[0004]
In visitor management using an ID card, an ID card with information for permitting admission to laboratories and event venues is issued, and this ID card is handed over to pre-registered prospective visitors. In addition, when the prospective person enters the laboratory or event hall, the information written on the ID card is read by the entrance inspection device provided at the entrance of the laboratory or event hall. Control such as opening the gate is performed.
[0005]
[Problems to be solved by the invention]
However, as described above, information such as the names of prospective visitors is registered in advance, and then when the visitors enter the research institute or event venue, the information entered by the visitors at the time of entry is registered in advance. Name and other information, and admission is permitted based on the result of the verification, the information to be verified is information that is easily known to others, such as the name and company name of the prospective visitor. There is a risk that other people who have not registered will be impersonated and will enter this information at the laboratory or event venue.
[0006]
In addition, in attendee management using an ID card, there is a cost for producing the ID card, and when the ID card is duplicated, a non-registered person uses the duplicated ID card to There is a problem of entering the event venue.
[0007]
Here, in recent years, with the rapid spread of mobile phones, various services using location information of mobile phones have been considered. Therefore, it is conceivable to perform the visitor management as described above using the position information of the mobile phone.
[0008]
When conducting location management using location information of mobile phones, the location of mobile phones possessed by prospective visitors is detected, and the mobile phones possessed by prospective visitors are expected to enter It is conceivable to perform processing such as permitting admission when it is confirmed that it exists at the entrance of the event venue.
[0009]
However, when the mobile phone is in a building or underground, the location information of the mobile phone cannot be acquired, and in detecting the location information of the mobile phone, the number of floors in the building, etc. The height of the place where the telephone is located cannot be specified. Further, in a place where high-rise buildings are dense, the position accuracy is lowered due to the multipath phenomenon. For this reason, there has been a restriction on visitor management using a mobile phone.
[0010]
The present invention has been made in view of the problems of the conventional techniques as described above, and provides an authentication system and an authentication apparatus that can perform authentication with high reliability without issuing an ID card. The purpose is to do.

In this embodiment, as shown in FIG. 1, a mobile phone 20 that can be connected to a public line 30, a telephone number database 41 in which predetermined telephone numbers of users are registered, and predetermined ringtones are registered. A ringtone database 42, a voiceprint information database 43 in which predetermined voiceprint information of a user is registered, a keyword database 44 in which predetermined keywords are registered, information input from the outside, and a telephone number database 41, the ring tone database 42, the voiceprint information database 43, the information registered in the keyword database 44, or the authentication device 10 that performs authentication based on the communication state of the mobile phone 20. In the present embodiment, only one mobile phone 20 is shown, but a plurality of mobile phones are provided so as to be connectable to the public line 30.
[0026]
Further, the authentication device 10 makes a call to the mobile phone 20 via the public line 30 when the telephone number is dialed by the input unit 1 including a key button for dialing the telephone number. Registered in the keyword database 44, the communication unit 2 to be established, the sound collection unit 3 that collects external sounds, the voice recognition unit 4 that recognizes the voice information included in the sound collected by the sound collection unit 3, A display unit 5 on which the keyword is displayed, a telephone number collation unit 6 that collates a telephone number dialed in the input unit 1 with a telephone number registered in the telephone number database 41, and a communication state in the communication unit 2 And whether the sound collected by the sound collection unit 3 is a ring tone in the mobile phone 20 called by the communication unit 2 based on the sound collected by the sound collection unit 3 The communication collating unit 7 to judge and the sound collecting unit 3 collect The received sound and the ringtone registered in the ringtone database 42, the ringtone matching unit 8, the voiceprint included in the sound collected by the sound collection unit 3 is analyzed, and the analyzed voiceprint And the voiceprint collation unit 9 that collates the voiceprint information registered in the voiceprint information database 43, the display control unit 11 that displays the keyword registered in the keyword database 44 on the display unit 5, and the voice recognition unit 4. Keyword collation unit 12 that collates voice information and keywords registered in keyword database 44, collation in telephone number collation unit 6, communication collation unit 7, ringtone collation unit 8, voiceprint collation unit 9, and keyword collation unit 12 The authentication control unit 13 performs authentication based on the result and outputs the authentication result.
[0027]
Hereinafter, an authentication process in the authentication system configured as described above will be described.
[0028]
FIG. 2 is a flowchart for explaining an authentication process in the authentication system shown in FIG.
[0029]
When a desired telephone number is dialed by inputting a telephone number to the input unit 1 (step S1), first, the telephone number matching unit 6 searches the telephone number database 41 (step S2). It is determined whether or not the telephone number input in 1 is registered in the telephone number database 41 (step S3), and the determination result is sent to the authentication control unit 13.
[0030]
Here, since the telephone number of the mobile phone possessed by the user registered in advance in the authentication system is registered in the telephone number database 41, the telephone number input in the input unit 1 is registered in the telephone number database 41. If not, the authentication control unit 13 outputs that the telephone number input to the input unit 1 cannot be authenticated as the second authentication result (step S4).
[0031]
If the telephone number input to the input unit 1 is registered in the telephone number database 41, the communication unit 2 performs a calling process using the telephone number input to the input unit 1 (step S5). ).
[0032]
When the communication unit 2 detects an incoming call at the mobile phone 20 by the call processing (step S6), the communication collating unit 7 collects sound at the timing when the communication unit 2 detects the incoming call at the mobile phone 20. It is detected whether or not the ring tone of the mobile phone 20 is collected via the unit 3 (step S7).
[0033]
When the ringtone of the mobile phone 20 is collected via the sound collection unit 3 at the timing when the communication unit 2 detects an incoming call in the mobile phone 20, the ringtone database 42 in the ringtone verification unit 8. Is searched (step S8), it is determined whether the ringtone collected via the sound collection unit 3 is registered in the ringtone database 42, and the determination result is output to the authentication control unit 13 (step S8). S9).
[0034]
Here, a predetermined ringtone is registered in the ringtone database 42, and the ringtone registered in the ringtone database 42 is set in the mobile phone possessed by the user registered in the authentication system. Has been.
[0035]
Thereby, when the ringtone collected through the sound collection unit 3 is not registered in the ringtone database 42, the authentication control unit 13 uses the sound collection unit 3 as a third authentication result as a ringtone. Is output that the mobile phone from which sound is collected cannot be authenticated (step S4).
[0036]
If the ringtone collected via the sound collection unit 3 is registered in the ringtone database 42, then “please press the call button” at a predetermined timing under the control of the display control unit 11. Is displayed on the display unit 5, and then the communication unit 2 detects whether or not the mobile phone 20 is set in a call state by operating the hook button by the user of the mobile phone 20 (step S10). ).
[0037]
When the communication unit 2 detects that the mobile phone 20 is set in a call state, the communication verification unit 7 detects that the communication unit 2 detects that the mobile phone 20 is set in a call state Then, it is detected whether or not the ringtone of the mobile phone 20 collected by the sound collection unit 3 is stopped, and the detection result is output to the authentication control unit 13 (step S11).
[0038]
Here, since the ring tone should not be output from the mobile phone set to the call state, the sound collection unit 3 is also detected at the timing when the communication unit 2 detects that the mobile phone 20 is set to the call state. In the case where the ringtone of the mobile phone 20 that has been collected by the mobile phone 20 does not stop, the authentication control unit 13 authenticates the mobile phone that has collected the ringtone by the sound collection unit 3 as the first authentication result. It is output that it cannot be performed (step S4).
[0039]
When the ringing tone of the mobile phone 20 collected by the sound collection unit 3 is stopped at the timing when the communication unit 2 detects that the mobile phone 20 is set to the call state, In the display control unit 11, keyword information registered in the keyword database 44 is extracted. Here, the keyword information is, for example, a combination of a hint for inducing a keyword and a keyword corresponding to the hint, and the keyword “river” or the hint “entry” for the hint “mountain”. It is information such as the keyword “Yamada” for the “approver”, and it may be set for each telephone number, when there is no hint, or for each time zone. This information is assumed to be notified to the user in advance by means of e-mail or the like.
[0040]
Thereafter, for example, a message “Please speak the admission approver” is displayed on the display unit 5 as a message prompting the utterance of the keyword based on the keyword information extracted based on the user information (step S12).
[0041]
Next, in the voice recognition unit 4, it is detected whether or not voice information is collected through the sound collection unit 3 (step S13).
[0042]
When the voice information is collected through the sound collection unit 3, the voice information collected through the sound collection unit 3 is recognized by the voice recognition unit 4 (step S14). Note that the voice information may be uttered to the mobile phone 20 and collected through the public line 30.
[0043]
Next, the keyword matching unit 12 determines whether the speech information recognized by the speech recognition unit 4 matches the keyword information extracted from the keyword database 44, and outputs the determination result to the authentication control unit 13. (Step S15).
[0044]
Here, when the voice information recognized by the voice recognition unit 4 does not match the keyword extracted from the keyword database 44, the sound collection unit 3 collects the sound as the fourth authentication result in the authentication control unit 13. The fact that the voice information cannot be authenticated is output (step S4).
[0045]
If the voice information recognized by the voice recognition unit 4 matches the keyword extracted from the keyword database 44, the voiceprint collation unit 9 then selects the voice collected through the sound collection unit 3. The voiceprint is analyzed (step S16), the voiceprint information database 43 is further searched (step S17), and whether or not the voiceprint of the voice collected via the sound collection unit 3 is registered in the voiceprint information database 43 is checked. The determination result is output to the authentication control unit 13 (step S18).
[0046]
In the voiceprint information database 43, since the voiceprint of the user registered in the authentication system in advance is registered, the voiceprint of the voice collected through the sound collection unit 3 is registered in the voiceprint information database 43 The authentication control unit 13 outputs an authentication result indicating that the authentication was successful (step S19), and the voiceprint of the voice collected via the sound collection unit 3 is not registered in the voiceprint information database 43. In this case, as the fifth authentication result, the fact that the voice collected through the sound collecting unit 3 cannot be authenticated is output (step S4).
[0047]
The authentication result output from the authentication control unit 13 is sent to another control device, and control using the authentication result is performed. For example, in a laboratory or event venue, it is possible to perform control such that a gate or a door is opened only when authenticated by this authentication system, or to verify the identity of an ID card such as a credit card. In that case, information such as the name of a user who has a mobile phone having a telephone number registered in the telephone number database 41 is registered in a database (not shown), and the authentication process is performed. Can be registered on the database to manage users who have already entered. In addition to the user's name, company name, and telephone number as entrance schedule information, it is also possible to register the scheduled entrance date and time in advance and manage whether the user entered at the registered scheduled entrance date and time. It is done. These registrations are made by the user notifying the administrator of the authentication system using telephone, fax, e-mail, etc., or inputting information using a predetermined information screen, and this information is transferred to a network such as the Internet. It is conceivable that the authentication system administrator is notified via the authentication system, and thereafter the authentication system administrator performs the notification.
[0048]
In this embodiment, authentication is performed based on collation results in all collation means of the telephone number collation unit 6, the communication collation unit 7, the ring tone collation unit 8, the keyword collation unit 12, and the voiceprint collation unit 9. If all one of the collation results in these collation means is used, and any one of the telephone number collation unit 6, the communication collation unit 7, and the ring tone collation unit 8 is included, authentication using the mobile phone 20 is performed. It can be carried out. However, if the number of verification means is large, the accuracy of authentication will be improved.
[0049]
Further, in keyword matching, it is conceivable that a voice is output from a speaker (not shown) without displaying the keyword on the display unit 5. Further, when the keyword consists of numbers, the sound collecting unit 3 Instead of detecting whether or not a keyword has been collected, it is also conceivable that the keyword is input to the input unit 1 and whether or not the keyword is input to the input unit 1 is detected.
[0050]
(Second Embodiment)
FIG. 3 is a diagram showing a second embodiment of the authentication system of the present invention.
[0051]
As shown in FIG. 3, the present embodiment is expressed by sound, such as a mobile phone 120 that can be connected to the Internet 130, an information transmission server 150 that provides information identifiable by sound in the sound information 130, and is provided on the Internet 130. Authentication is performed by collecting sound information database 140 in which information is registered and sound information output from mobile phone 120 and recognizing information embedded in the collected sound information with reference to sound information database 140 And an authentication device 110 that performs the above.
[0052]
In addition, the information transmission server 150 generates a sound information generation unit 151 that generates sound information in which predetermined information is incorporated with reference to the sound information database 140, and is generated by the sound information generation unit 151 by an operation on the mobile phone 120. The sound information transmitting unit 152 transmits the sound information to the mobile phone 120 via the Internet 130.
[0053]
In addition, the authentication device 110 collects sound information output from the mobile phone 120 and collects information included in the sound information collected by the sound collection unit 103 into a sound information database. 140, the sound information recognition unit 108 recognized with reference to 140, and the authentication control unit 113 that performs authentication based on the information recognized by the sound information recognition unit 108 and outputs an authentication result.
[0054]
Hereinafter, an authentication process in the authentication system configured as described above will be described.
[0055]
FIG. 4 is a flowchart for explaining an authentication process in the authentication system shown in FIG.
[0056]
First, in the sound information generation unit 151 of the information transmission server 150, the sound information database 140 is referred to, and sound information expressing predetermined information is generated (step S21). Here, in the sound information database 140, predetermined information is registered corresponding to each sound. For example, information “0” for the sound “do”, information “1” for the sound “le”, and sound “mi” The information “2”, the information “3” for the sound “Fa”, the information “4” for the sound “So”, and the scale “La” The information “5” is registered for the sound “”, and the information “6” is registered for the sound “si”. In this case, in the sound information generation unit 151, for example, when expressing information “1234”, the sound information database 140 is referred to, and sound information including a sound “Remifaso” is generated. In addition to this, it is conceivable that information is expressed by the length of a note, a chord, or a semitone.
[0057]
Thereafter, when downloading of the sound information is requested in the mobile phone 120 (step S22), the sound information generated by the sound information generation unit 151 is transmitted from the sound information transmission unit 152 of the information transmission server 150 ( Step S23). Here, it is conceivable that the request for downloading the sound information in the mobile phone 120 is made using identification information that can identify the information to be downloaded. In this case, the sound information transmission unit 152 uses the sound information generation unit 151. The sound information identified by the identification information designated by the mobile phone 120 is transmitted among the sound information generated in step S2.
[0058]
The sound information transmitted from the sound information transmitting unit 152 of the information transmission server 150 is received by the mobile phone 120 via the Internet 130 and stored in the memory in the mobile phone 120 (step S24).
[0059]
Thereafter, the user who possesses the mobile phone 120 outputs the sound information transmitted from the information transmission server 150 and stored in the memory of the mobile phone 120 toward the sound collection unit 103 of the authentication device 110 (step S25). When the sound information is collected by the sound collection unit 103 of the authentication apparatus 110 (step S26), the sound information database 140 is referred to by the sound information recognition unit 108 in the authentication apparatus 110, and the sound collection unit 103 is referred to. Information represented by the collected sound information is recognized (step S27).
[0060]
Thereafter, the authentication control unit 113 determines whether the information recognized by the sound information recognition unit 108 is predetermined information, and outputs a determination result (step S28). Note that the predetermined information is information for performing authentication by the authentication device 110 and is also notified to the information transmission server 150 in advance. In the information transmission server 150, sound information in which the predetermined information is expressed is generated.
[0061]
Further, if the predetermined information can be generated by a common logic between the information transmission server 150 and the authentication device 110, the voice information database 140 is shared by the information transmission server 150 and the authentication device 110. Since it becomes unnecessary, the sound information generated by the information transmission server 150 can be determined by the authentication device 110 with a predetermined logic, and can be operated even in an offline state. For example, when information such as “the owner of the mobile phone number XXX visits the XX laboratory on the day of the month” is input to the information transmission server 150, based on a predetermined logic. The generated sound information is transmitted to the mobile phone 120, and the authentication apparatus 110 analyzes the sound information collected from the mobile phone 120 with a predetermined logic and recognizes the information input to the information transmission server 150. It will be. Thereby, the information produced | generated by the logic common between the information transmission server 150 and the authentication apparatus 110 can be utilized as authentication information.
[0062]
The authentication result output from the authentication control unit 113 is sent to another control device, and control using the authentication result is performed. For example, in a laboratory or an event venue, it is conceivable that control is performed such that a gate or a door is opened only when authenticated by this authentication system, or a predetermined card is issued.
[0063]
【The invention's effect】
As described above, in the present invention, an authentication unit is provided that is connected to a public line and performs authentication based on the timing of the incoming call and the start of the call on the mobile phone and the timing of the ringing sound on the mobile phone. It is possible to perform authentication with high reliability using a telephone.
[0064]
In addition, information transmitting means for providing information identifiable by sound in sound information, sound information storing means for storing sound information provided from the information transmitting means, and sound information output from the sound information storing means Similarly, a device provided with an authentication unit that identifies embedded information and performs authentication based on the identified information can be authenticated with high reliability using a mobile phone.
