The present invention is in the field of methods, systems, and computer program products to improve fraud detection on conference calling systems based on observation of participants' call time durations.
A conference call (also known as a “teleconference” or a “teleconference call”) is a telephone call in which the calling party wishes to have more than one called party participate in the audio portion of the call. The conference call may be designed to allow the called party to participate during the call, or the call may be set up so that the called party merely listens into the call and cannot speak. It is often referred to as an ATC (Audio Tele-Conference). In addition to audio, conference calls can include video, multimedia and other communication methods.
Conference calls can be designed so that the calling party calls the other participants and adds them to the call; however, participants are usually able to call into the conference call without assistance from an “operator” of the conference system, by dialing into a special telephone number that connects to a “conference bridge” (a specialized type of equipment that links telephone lines).
Companies commonly use a specialized service provider who maintains the conference bridge, or who provides the phone numbers and PIN codes that participants dial to access the meeting or conference call.
An embodiment of the invention includes a method for detecting fraud in a conference calling system. One or more time duration thresholds are received for a conference call. In at least one embodiment, an attendee duration threshold (also referred to herein as the “first call duration threshold”) is received, which indicates a maximum allowed call duration for an attendee of the conference call. A participants threshold (also referred to herein as the “second call duration threshold”) is also received, which indicates a maximum allowed total call duration for all of the attendees of the conference call combined; and, a conference call threshold (also referred to herein as the “third call duration threshold”) is received, which indicates a maximum allowed call duration for the conference call.
The conference call is monitored to determine an attendee duration, a participants duration, and/or a conference call duration (also referred to herein as the “first call duration”, “second call duration”, and “third call duration”, respectively). The attendee duration represents the call duration of an attendee of the conference call. The participants duration represents the total call duration of all of the attendees combined; and, the conference call duration represents the call duration of the conference call.
The time duration thresholds are compared to the attendee duration, participants duration, and/or conference call duration. If the respective time duration thresholds exceed the attendee duration, participants duration, and/or conference call duration, the conference call is allowed to continue. However, actions are performed by a processor if the attendee duration, participants duration, and/or conference call duration exceeds the time duration thresholds.
In at least one embodiment, a passcode to enter the conference call is received from an attendee exceeding the attendee duration threshold. User information is received from the person assigned the passcode, wherein the user information includes an employee number, an identification badge number, a home telephone number, a home address, a mobile telephone number, an e-mail address, an office telephone number, an office address, and/or answer(s) to security question(s) entered by the person assigned the passcode. Validation information is obtained from the attendee exceeding the attendee duration threshold; and the validation information is compared to the user information. If the validation information matches the user information, an alert indicating that the time duration threshold has been exceeded is sent to the attendee who exceeded the attendee call duration threshold.
In at least one embodiment, the actions include sending an alert indicating that the time duration threshold has been exceeded to an administrator of the conference calling system, a moderator of the conference call, participants of the conference call, and a security personnel. In another embodiment, the actions further include permitting the administrator to enter the conference call, terminating the conference call, and/or voiding a passcode to the conference call. In another embodiment, the actions include generating and storing a report, where the report includes the time duration thresholds, the attendee duration, the participants duration, the conference call duration, a passcode, and the actions performed.
The present invention is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
Exemplary, non-limiting embodiments of the present invention are discussed in detail below. While specific configurations are discussed to provide a clear understanding, it should be understood that the disclosed configurations are provided for illustration purposes only. A person of ordinary skill in the art will recognize that other configurations may be used without departing from the spirit and scope of the invention.
In order to connect to the conference calling system 100, the participants 130, 140, and 150 use a reservationless bridge. The bridge setup is dynamic, wherein a call-in telephone number and a passcode from the conference moderator 120 are sufficient to begin the conference call. The participants 130, 140, and 150 have the same passcode (i.e., Passcode A), which is different from the passcode of the conference moderator 120 (i.e., Passcode Z). In another embodiment of the invention, the participants 130, 140, and 150 have different passcodes (e.g., Passcodes A, B, and C, respectively). In one embodiment, the intruder 160 has the conference moderator 120's passcode (i.e., Passcode Z). In another embodiment, the intruder 160 utilizes a participant's passcode (i.e., Passcode A, B, or C, depending on how passcodes are assigned) to connect to the conference calling system 100.
The conference system administer 110 configures the conference calling system 100 and assures its operation. These functions are embodied in the service provider of the conference calling system (not shown). However, in one embodiment, these functions are delegated to the purchaser of the conference calling service. In another embodiment, an automatic monitoring system is utilized to configure the conference calling system 100 and assures its operation.
Having the conference moderator 120's passcode, the intruder 160 can either enter a conference call as an attendee during a legitimate meeting; or, the intruder 160 can establish an illegitimate meeting between himself and other intruders. In the fraud scenario illustrated in
In one example of fraud, the intruder 160 connects to the conference calling system and waits until a conference call begins. This allows the intruder 160 to obtain information during the conference call. The intruder 160 is also allowed to use the conference calling system for other purposes after the moderator 120 and participants 130-150 disconnect from the conference calling system, for example, holding another conference call by sharing the moderator passcode with others. As described in more detail below, an embodiment of the invention includes a method to protect conference calling systems from fraudulent usage by detecting excessive duration of a conference call, excessive duration of an individual attendee, and/or excessive total duration (i.e., connection time) of all participants combined.
During the preparation phase, a threshold for the maximum time duration allowed for an individual attendee (referred to herein as the “first threshold” or “attendee duration threshold”) is set (210). This time duration begins when the attendee (i.e., moderator or participant) logs into the conference calling system using his or her password, and ends when the attendee disconnects from the conference call. For example, if the attendee threshold is set at 60 minutes, and the moderator has been logged into the conference calling system for 70 minutes, then the attendee threshold has been exceeded.
A threshold for the maximum time duration allowed for all of the participants (referred to herein as the “second threshold” or “participants threshold”) is also set (220). This time duration combines the amount of time that all of the participants are connected to the conference calling system. For example, if the participants threshold is set at 90 minutes, participant A is connected to the conference calling system for 30 minutes, participant B is connected to the conference calling system for 28 minutes, participant C is connected to the conference calling system for 31 minutes, and there are only 3 participants connected to the conference calling system, then the total combined time of the participants is 89 minutes and the participants threshold is not exceeded.
A threshold for the maximum time duration allowed for the conference call to take place (referred to herein as the “third threshold” or “conference call threshold”) is also set (230). This time duration begins when the first attendee is connected to the conference calling system, and ends when the last attendee disconnects from the conference calling system. For example, if the conference call threshold is set for 120 minutes, the first attendee connects to the conference calling system at 11:58 a.m., and the last attendee disconnects from the conference calling system at 1:30 p.m., then the conference call threshold is not exceeded. In an alternative embodiment, this time duration begins at the time the conference call was scheduled to begin (e.g., 12:01 p.m.).
In another alternative embodiment, one or more of the thresholds are omitted and/or an additional threshold is defined in the preparation phase. For example, in at least one embodiment, a threshold for the maximum time duration allowed for one particular attendee (e.g., the participant entered passcode C) is set. In at least one embodiment, the moderator and/or conference system administrator is able to adjust the first, second and/or third thresholds during the conference call in order to allow for additional time to conduct the conference call.
Response actions (e.g., notify conference system administrator) are also set up during the preparation phase (240). The conference calling system will perform the response actions if either the attendee threshold, participants threshold, and/or conference call threshold has been exceeded, as more fully described below with reference to
Furthermore, the conference calling system determines whether the participants threshold has been exceeded (330). If the participants threshold has been exceeded, the method performs response actions. For example, the conference calling system sends an alert to the moderator if the participants threshold is set for 60 minutes and a participant has been logged into the conference calling system for 75 minutes.
Additionally, the conference calling system determines whether the conference call threshold has been exceeded (340). If the conference call threshold has been exceeded, the method performs response actions. For example, the conference calling system terminates the conference call if the conference call threshold is set for 120 minutes and it has been over 120 minutes since the first attendee logged into the conference calling system.
In an alternative embodiment, the method determines whether the thresholds are exceeded in a different order, e.g., the method determines whether the conference call threshold has been exceeded prior to determining whether the participants threshold has been exceeded. In another alternative embodiment, the method monitors whether the thresholds have been exceeded simultaneously. In yet another alternative embodiment, one or more of the thresholds are omitted and/or the method includes an additional threshold.
The method continues to monitor whether any of the thresholds are exceeded until all of the thresholds have been exceeded or until the last attendee disconnects from the conference calling system (i.e., the conference call is ended (350)). In at least one embodiment of the invention, the method determines whether the thresholds have been exceeded in pre-defined intervals set during the preparation phase. For example, the method determines whether the thresholds have been exceeded every 5 minutes. In another embodiment, the method continually monitors the time durations of the attendees and the total conference call duration, such that response actions are performed immediately after a threshold is exceeded.
The processor determines whether to alert the moderator (409). The “true moderator” is the actual person that has been assigned the moderator passcode by the conference calling system or the conference system administrator. The true moderator is alerted if that person is known by the conference calling system; or, if the true moderator is not known by the conference calling system, all of the moderators that have entered the moderator passcode are alerted by the processor, i.e., the true moderator and the intruder if masquerading as a moderator (410). The alert includes a notification that a threshold defined in the preparation phase has been exceeded (e.g., the allowed duration for the conference call has been exceeded). In at least one embodiment of the invention, the alert also includes the thresholds defined in the preparation phase, the amount of time each attendee has been logged into the conference calling system, and the duration of the conference call. In at least one embodiment, the alerts include a time stamped e-mail, text message, instant message, facsimile, and/or other form of communication indicating that a threshold has been exceeded.
The processor determines whether to send an alert to the conference system administrator (419). If the conference system administrator is alerted by the processor (420), further actions are automatically or manually performed by the conference system administrator. In at least one embodiment of the invention, such actions are setup prior to initiation of the conference call (e.g., during the preparation phase). Furthermore, the processor determines whether to terminate the conference call (429). If the conference call is terminated by the processor (430), attendees of the conference call are notified that a threshold has been exceeded.
The processor determines whether to lock one or more of the passcodes of the attendees in order to prevent future access to the conference calling system (439). If a passcode is locked by the processor (440), one or more of the attendees are notified that a passcode has been locked. Based on the response actions defined in the preparation phase, the passcode is either temporarily or permanently locked. For example, in one embodiment of the invention, Participant C is notified that his passcode has been permanently locked; and, he is given contact information for the conference system administrator in order to obtain a new passcode.
In addition, the processor determines whether to log information for future reference and reporting into, for example, a report database (449). The processor logs information (450) by saving a report of the occurrence, wherein the report includes, for example, at least one of the thresholds defined in the preparation phase, the duration of the conference call, the amount of time each attendee has been logged into the conference calling system, the passcodes of each attendee, the telephone numbers of the attendees that called into the conference calling system (obtained from a caller-identification system), the time and date that the threshold(s) were exceeded, and a detailed description of the response action(s) taken, e.g., identification of personnel who received alerts from the conference calling system. Information in the report is utilized to identify trends, track moderator ID and/or passcode usage, and/or for detailed review by the conference system administrator and/or personnel within the true moderator's company. For example, in at least one embodiment, the conference system administrator compares reports that have been collected over time in order to identify trends, such as a particular passcode that repeatedly violates a threshold and/or a particular time of day that a threshold is frequently violated.
In an alternative embodiment, the response actions illustrated in
In another embodiment of the invention, the processor also determines whether to alert others (in addition to or alternatively to the person assigned the passcode and/or the moderator). Alerting others includes sending an alert indicating that a threshold has been exceeded to at least one of administrative personnel of the conference calling system provider and security personnel employed by the true moderator's company who is responsible for tracking risks and investigating fraud across the company.
An electronic timer 620 monitors the conference call to determine an attendee duration, a participants duration, and/or a conference call duration (also referred to herein as the “first call duration”, “second call duration”, and “third call duration”, respectively) (520). In at least one embodiment, the timer 620 includes at least a first timer, a second timer, a third timer, and a fourth timer. The attendee duration represents the call duration of an attendee of the conference call. In at least one embodiment, the attendee duration is determined by activating the first timer of the timer 630 when the attendee (i.e., moderator or participant) enters the conference call system using his or her passcode, and stopping the first timer when the attendee disconnects from the conference call.
The participants duration represents the total call duration of all of the attendees combined. For example, in at least one embodiment, the first timer times the call duration of a moderator (attendee A); the second timer times the call duration of a first participant (attendee B); and, the third timer times the call duration of a second participant (attendee C). If attendee A is connected to the conference call for 30 minutes, attendee B is connected to the conference call for 28 minutes, attendee C is connected to the conference call for 31 minutes, and there are only 3 attendees connected to the conference call, then the total combined time of the attendees is 89 minutes. The total combined time of the attendees is determined by the timer 620 and/or a processor 630 connected to the timer 620.
The conference call duration represents the call duration of the conference call. In at least one embodiment, the conference call duration is determined by activating the fourth timer of the timer 620 when the first attendee to join the conference call is connected to the conference call, and stopping the fourth timer when the last attendee to exit the conference call disconnects from the conference call. The electronic timer 620 continues to monitor whether any of the thresholds are exceeded until all of the thresholds have been exceeded or until the last attendee disconnects from the conference calling system (i.e., the conference call is ended
The processor 630 compares the time duration thresholds to the attendee duration, participants duration, and/or conference call duration (530). If the time duration thresholds exceed the attendee duration, participants duration, and/or conference call duration, the conference call is allowed to continue. However, actions (also referred to herein as “response actions”) are performed by the processor 630 if the attendee duration, participants duration, and/or conference call duration exceeds the time duration thresholds (540).
In at least one embodiment, if an attendee violates the attendee duration threshold, a receiver 640 obtains the passcode entered by that attendee. User information (also referred to herein as “first information”) is received from the person assigned the passcode, wherein the user information includes an employee number, an identification badge number, a home telephone number, a home address, a mobile telephone number, an e-mail address, an office telephone number, an office address, and/or answer(s) to security question(s) entered by the person assigned the passcode. Validation information (also referred to herein as “second information”) is obtained from the attendee exceeding the attendee duration threshold; and the validation information is compared to the user information. If the validation information matches the user information, an alert is sent to the attendee who exceeded the attendee call duration threshold from an alert module 632 in the processor 630. In at least one embodiment, the alert includes a time stamped e-mail, text message, instant message, facsimile, and/or other form of communication indicating that the time duration threshold has been exceeded.
In at least one embodiment, the actions further include sending the alert to an administrator of the conference calling system, a moderator of the conference call, participants of the conference call, and/or security personnel of the teleconference provider and/or at least one company employing a participant of the teleconference call. In another embodiment, the actions further include permitting the administrator to enter the conference call, terminating the conference call, and/or voiding a passcode to the conference call. For example, in at least one embodiment, a passcode is voided or temporarily disabled after 5 unsuccessful attempts to access the conference calling system in a 24 hour period.
In another embodiment, a report generating module 634 in the processor 630 generates and stores a report (e.g., in an electronic database), where the report includes the time duration thresholds, the attendee duration, the participants duration, the conference call duration, a passcode, and the actions performed. In yet another embodiment, the alert module 632 and report generating module 634 are outside of the processor 630. Information in the report is utilized to identify trends, track moderator ID and/or passcode usage, and/or for detailed review by the conference system administrator and/or personnel within the true moderator's company. For example, in at least one embodiment, the conference system administrator compares reports that have been collected over time in order to identify trends, such as a particular passcode that repeatedly violates a threshold and/or a particular time of day that a threshold is frequently violated.
Accordingly, an embodiment of the invention includes systems and methodologies to investigate potential fraudulent activity on conference calling systems. The occurrence of a potential fraudulent condition is identified, such that rapid response actions may be taken. The embodiments of the invention can save thousands of dollars in fraudulent toll charges. Moreover, the ability to identify fraudulent activity can prevent the loss of information.
