AUTHENTICATION SYSTEM FOR ATTENDANDING OF CONFERENCE}

The present invention relates to an authentication system for joining a conference, and more particularly, to an authentication system for improving authentication security of conference participants.

Recently, multi-party conferences have been conducted to facilitate meetings without members gathering in one place. Various systems and methods have been provided to support such conferences.

If a host who requires a conference call calls the conference call center and requests a conference call, the conference call center's operator will provide a conference room at the request of the organizer, and the host will be authorized to enter the conference room. Give a number.

1 is a flowchart illustrating an operation of an authentication system for participating in a conventional conference. Referring to the drawings, when attendees who have been given an authentication number from the host to participate in the conference call call the conference call center to enter the conference call, the conference call center receives the call of the attendees (S10) and the attendee DTMF is recognized by inputting the authentication number as DTMF (DUAL TONE MULTI FREQUENCY) through the phone button from the phone (S20).

Subsequently, the authentication number input from the attending client is compared with the authentication number stored in the reservation information DB (Data Base, 10) to determine whether the authentication number input from the attending client matches the authentication number stored in the reservation information DB (S30).

If it is determined that the authentication number input from the attending client matches the authentication number stored in the reservation information DB 10, the system joins the attending client in the meeting (S40), and the authentication number input from the attending client is the reservation information DB 10. If it is determined that it does not match the authentication number stored in the repeatedly requested to repeatedly press the authentication number from the requesting client within the limited number is compared with the authentication number stored in the reservation information DB (10).

In the conventional authentication system, since the number entered from the requesting client is the authentication number and the meeting identification number, if the attending client mistakenly enters another authentication number, he / she may unintentionally enter a conference call of a third party. It causes a problem that the contents of meetings of other companies are easily leaked to the outside.

In addition, if the attending client knows the authentication number of the third-party conference call on purpose, the attending client can participate in the conference call of the third party with a single authentication number, which causes the third party to extract information from the third-party conference call and cause serious damage to the third party. Cause problems.

In order to solve the above problems, an object of the present invention is to provide an authentication system for participating in the meeting to prevent the leakage of the meeting content to the outside by providing a two-step authentication system.

In order to achieve the above object, the authentication system for participating in the meeting of the present invention, reservation information DB that stores the reservation information in the form of a text including a meeting room number, authentication number, authentication words and meeting time; A voice file generation module for converting an authentication word from the reservation information loaded from the reservation information DB into an analog standard voice file; A voice file DB for storing conference room information including the conference room number, authentication number, standard voice file, and conference time; A DTMF authentication module that receives an authentication number from the requesting client and activates reservation information of a time zone corresponding to the authentication number provided from the reservation information DB; A voice transmission module for receiving an analog authentication word made up of a client by attendance; Receives meeting room information corresponding to the reservation information activated by the DTMF authentication module from the voice file DB, selects a standard voice file by comparing the voice of the attendant received from the voice transmission module with the voice of the authentication word of the attending client, and corresponds to the selected authentication word. Voice comparison module for checking the meeting room number; And an entry processing module for allowing the attendee who completed the voice authentication to participate in the meeting of the corresponding authentication number.
The entrance processing module compares the meeting room number corresponding to the authentication number with the meeting room number corresponding to the authentication word, and if the meeting room number corresponding to the authentication number and the meeting room number corresponding to the authentication word are determined to be the same, requesting client Participate in the conference call, and if it is determined that it is not the same, one of the meeting room number corresponding to the authentication number and the meeting room number corresponding to the authentication word can be selected from the attending clients, and the attending client may participate in the selected meeting room. .
The admission processing module provides a guide voice for re-confirming the authentication number to the attending client, and if the provided authentication number is selected from the attending client, enters the conference room corresponding to the authentication number, and if the authentication number is not selected, it corresponds to the authentication word. You can enter the conference room.
The voice comparison module compares the analog waveform pattern of the authentication word standard voice file corresponding to the activated conference room with the analog waveform pattern of the authentication word voice provided from the attending client, and compares the authentication word standard voice file of the activated conference room. If the analog waveform and the analog waveform pattern of the authentication word voice provided from the attending client is equal to or greater than a predetermined reference value, the analog waveform may be determined and selected.

A diagram for describing a detailed operation of an authentication system for participation.

Referring to FIG. 2, the authentication system for participating in a conference according to the present invention performs a two-stage authentication to perform a two-step authentication processing unit 100 to participate in an attending client, and performs voice authentication through an authentication word provided from the attending client. It includes a voice authentication unit 200.

The dual authentication processing unit 100 converts the authentication word of all reservation information into a standard voice file and stores the voice file generation request module 120 for receiving and transmitting the reservation information from the reservation information DB 300, and the telephone from the attending client. DTMF authentication module 140, which receives the authentication number input through the button and activates and transmits the meeting room corresponding to the authentication number from the reservation information DB 300, and compares with the authentication word of the meeting room corresponding to the authentication number The voice transmission module 160 transmits the authentication word provided from the attending client so that the voice authentication is performed, and the admission processing module 180 joins the attendee who completed the voice authentication in the conference call.

In addition, the voice authentication unit 200 converts the authentication word of all reservation information transmitted from the voice file generation request module 120 into a standard voice file and stores it in the voice file DB 400 and the voice file generation module 220. The standard voice file of the authentication word corresponding to the conference room transmitted from the DTMF authentication module 140 is loaded from the voice file DB 400 and selected by comparing with the voice of the authentication word provided from the attending client and corresponding to the selected authentication word. It consists of a voice comparison module 240 to check the meeting room number.

The reservation information DB 300 stores the meeting room information reserved by the meeting organizer as a text file. As the meeting room information, for example, the meeting room number, the day of the meeting is held, the time when the meeting starts, the authentication number and the authentication word. May consist of one recorder. In addition, the voice file DB 400 stores conference room information including an authentication word converted into a standard voice file among conference room information stored in the reservation information DB 300.

As described above, in order to transmit the conference room information in the reservation information DB 300 to the voice file DB 400, the voice file generation request module 120 is connected to the reservation information DB 300, and such a voice file generation is performed. The request module 120 loads conference room information from the reservation information DB 300 and transmits a text file to the voice file DB 400.

When the meeting room information of the text file is transmitted from the voice file generation request module 120, the voice authentication unit 200 is provided with a voice file generation module 220 to convert the transmitted meeting information into a standard voice file. The voice file generation module 220 converts an authentication word in a text form of the conference room information transmitted from the voice file generation request module 120 into a standard voice file, and includes a conference word including the authentication word converted into a standard voice file. The information is transmitted to the voice file DB 400. Here, the standard voice file refers to a voice file in which age, gender, tone, tone, and the like are standardized.

Due to this, the same information of the conference room stored in the reservation information DB 300 is stored in the voice file DB 400, but the voice file DB 400 is stored in a state in which the authentication word is converted into a standard voice file. .

DTMF authentication module 140 receives the authentication number from the attending client for participation in the meeting serves to perform authentication by comparing with the authentication numbers stored in the reservation information DB (300). That is, when the authentication number is pressed by the telephone call button from the attending client, the DTMF authentication module 140 compares the authentication number pressed from the attending client with the authentication numbers stored in the reservation information DB 300 and corresponds to the authentication number. Authentication is performed by activating the conference room information.

As shown in FIG. 3, if the authentication number provided from the attending client is '121' among the meeting room information stored in the reservation information DB 300, a time corresponding to 121 is used, for example, a meeting in which the meeting proceeds at 10:00 on Wednesday. It is possible to activate conference room information with rooms # 1, # 5, # 6, # 9.

In the above, the conference room information corresponding to the authentication number '121' is activated in consideration of both the day of the week and the meeting start time, but the conference room information is not limited thereto, and the conference room information (# 1, # 2, # is considered only on the day of the week). 5, # 6, # 8, # 9 may be activated or the conference room information (# 1, # 5, # 6, # 9) may be activated in consideration of the meeting start time.

Conference room information corresponding to the authentication number from the DTMF authentication module 140 is transmitted to the voice comparison module 240 of the voice authentication unit in the form of a text file, the voice comparison module 240 to the authentication number from the voice file DB (400) Recall and save the authentication word of the relevant meeting room information. Here, the authentication word of the conference room is imported from the voice file DB (400) is stored as a standard voice file of the analog waveform form.

In order to perform voice authentication compared to the stored standard voice file as described above, the voice transmission module 160 of the dual authentication processing unit 100 receives a desired authentication word as an analog waveform type voice by requesting a requesting client to attend. It is transmitted to the voice comparison module 240.

When the standard voice file of the meeting room authentication word corresponding to the authentication number and the voice provided from the attending client are stored in the voice comparison module 240, the voice comparison module 240 compares the waveforms of the two voices and selects the selected voice. Check the meeting room number. Here, when comparing the authentication word of the meeting room corresponding to the authentication number and the authentication word provided by the voice from the requesting client in order to increase the authentication efficiency, if the two authentication words are not the same or more than a predetermined reference value, for example, 60% or more Can be performed.

For example, as shown in FIG. 4, if the authentication word 500 of the conference room corresponding to the authentication number is 'Dobongsan', and the authentication word 600 provided from the attending client is 'Dobangsan', the area A and the area C It may be determined that the region having the same pattern and the region B have different patterns, and the two words are about 66.6% similar. As a result, since the two words are more than 60% similar, they may be determined to be the same and authentication may be performed.

When the authentication is performed by the similarity of the two authentication words as described above, it is possible to increase the authentication efficiency by reducing the search time, and the mutual hit rate between the two authentication words can be improved by 40% or more. This usually operates as about 40,000 words stored in the voice file DB, but using the method described above, the search rate can be improved within 500 words in the conference room corresponding to the authentication number, thereby improving the hit rate and speed. .

When the voice authentication is completed from the voice comparison module 240, the comparison value of the two authentication words is transmitted to the entrance processing module 180, and the entrance processing module 180 may allow the attending client to participate in the authenticated meeting.

More specifically, the admission processing module 180 determines whether or not the meeting room number corresponding to the authentication number and the meeting room number corresponding to the authentication word in order to participate in the meeting requestor, the meeting corresponding to the authentication number If the room number and the meeting room number corresponding to the certified word are the same, the requesting client can participate in the meeting.

Hereinafter, the operation of the authentication system for participating in a conference according to the present invention will be described with reference to FIGS. 5 and 6.

First, when the attending client calls the call center to participate in the conference call, the DTMF authentication module 140 receives the call of the attending client (S100) and allows the attending client to find a conference room that the attending client wants to enter. By operating the (Automated Response System) function, the authentication number is received as DTMF and recognized (S200).

Subsequently, the authentication number of the attending client is selected by comparing with the authentication number stored in the reservation information DB 300, and the conference room for the time zone corresponding to the selected authentication number is activated to confirm the authentication number (S300). On the other hand, if the authentication number is not confirmed, the process returns to the step of recognizing the DTMF (S200).

When the meeting room corresponding to the authentication number is activated as described above, the client waits to receive a voice recording from the requesting client (S400), and the client requests to record the authentication word by voice while waiting for the voice recording (S500).

Subsequently, the voice data recorded from the attending client is transmitted to the voice comparison module 240, and the authentication word is checked by comparing analog waveforms to match or similar to the authentication word of the conference room corresponding to the authentication number. (S600). On the other hand, if the authentication word is not confirmed, the process returns to the step of recording the voice of the attendee (S500).

As described above, after confirming the authentication word, it is determined whether the meeting room number corresponding to the authentication number and the meeting room number corresponding to the authentication word are the same (S700), and the meeting room number and the authentication word corresponding to the authentication number. If it is determined that the corresponding meeting room number is the same, the requesting client enters the meeting (S800).

For example, as shown in Figure 6, when the authentication number and the words provided from the attending client is recognized as '121' and 'Dobongsan', respectively, the corresponding meeting room number is the same, so the attending client is in meeting room # 1 You enter.

On the other hand, if it is determined that the meeting room number corresponding to the authentication number provided by the attending client and the meeting room number corresponding to the authentication word do not match, the requesting client selects the authentication number and the meeting room number corresponding to the authentication word from the attending client. The sponsor may participate in the selected conference room.

For example, if the authentication number and the authentication word are recognized as '121' and 'Hallasan', respectively, the corresponding conference room numbers do not match, so the entrance processing module 180 may have a meeting room corresponding to each authentication number and authentication word. An authentication number or an authentication word may be selected so that any one of the numbers # 1 and # 5 is selected, thereby allowing the attending client to join the selected conference room.

More specifically, if it is determined that the meeting room number corresponding to the authentication number and the meeting room number corresponding to the authentication word are not the same, the entrance processing module 180 sends a guide voice 'Are the authentication number correct?' To the requesting client. Providing (S720), if the requesting client selects one of the telephone buttons to select the authentication number from the provided guidance voice, the attending client may enter the meeting room corresponding to the authentication number, for example, meeting room # 1. (S740).

On the other hand, if the attending client selects '2' in order to select that the authentication number is wrong, the admission processing module 180 determines that the meeting room corresponding to the authentication word is correct, and the attending client corresponds to the meeting room corresponding to the authentication word. Enter the second meeting room to complete the operation of the system (S760).

In the above, the admission processing module 180 provided the guide client with the guide voice 'Are the authentication number correct?' To the requesting client, but the guide voice 'Authentication word is correct?' Of course.

In the above, the attendant was provided with a guide voice for re-confirming the authentication number or the authentication word. However, the present invention is not limited thereto, and any one of the meeting room number corresponding to the authentication number and the authentication word is provided to the requesting client. It is of course possible to provide a guide voice for selection, and to invite the client to attend the conference room selected by the guide voice.

In addition, in the above, if it is determined that the meeting room number corresponding to the authentication number and the meeting room number corresponding to the authentication word are not the same, either the meeting room number for the authentication number or the meeting room number for the authentication word is sent to the requesting client. Although the guide voice is provided to select, the present invention is not limited thereto, and authentication may be performed by re-entering the authentication number and by re-entering the authentication word if the authentication number is consecutively wrong. Can be determined.

Although described above with reference to the drawings and embodiments, those skilled in the art that the present invention can be variously modified and changed within the scope without departing from the spirit of the invention described in the claims below I can understand.
