`
`ABSTRACT
`
`Disclosed is a secure telephone call management system for
`authenticating users of a telephone system in an institutional
`facility. Authentication ofthe users is accomplished by using
`a personal identification number, preferably in conjunction
`with speaker independent voice recognition and speaker
`dependent voice identification. When a user first enters the
`system, the user speaks his or her name which is used as a
`sample voice print. During each subsequent use ofthe system,
`the user is required to speak his or her name. Voice identifi-
`cation software is used to verify that the provided speech
`matches the sample voice print. The secure system includes
`accounting sofiware to limit access based on funds in a user’s
`account or other related limitations. Management sofiware
`implements widespread or local changes to the system and
`can modify or set any number of user account parameters.

`
`FIELD OF THE INVENTION
`
`
`
`
`
`
`
`
`The present invention relates generally to the field of tele-
`
`
`
`
`
`
`
`
`
`phone communication systems in penal institutions or similar
`
`
`
`
`
`
`
`facilities. In particular, the present invention relates to a com-
`
`
`
`
`
`
`
`
`puter-based telecommunication system with the capacity to
`
`
`
`
`
`
`
`allow an institution to authorize, control, record, monitor, and
`
`
`
`
`
`
`
`
`
`report usage and access to a telephone network using speaker
`
`
`
`
`
`
`
`
`
`independent voice recognition and speaker dependent voice
`
`
`
`
`
`
`
`identification to ensure that access is restricted to authorized
`
`
`
`
`
`
`
`
`
`
`
`
`users only.
`
`
`BACKGROUND OF THE PRESENT INVENTION
`
`
`
`
`
`
`
`
`
`
`
`Generally, the need to monitor, control, record and provide
`
`
`
`
`
`
`
`
`
`detailed records of the usage of a telephone system in a
`
`
`
`
`
`
`
`
`
`
`controlled institutional environment is well recognized. It is
`
`
`
`
`
`
`
`common to utilize a controlled telephone system capable of
`
`
`
`
`
`
`
`
`monitoring outgoing telephone connections in many types of
`
`
`
`
`
`
`
`
`institutional environments, such as, but not limited to, penal
`
`
`
`
`
`
`
`
`
`institutions, military institutions, hospitals, schools, busi-
`
`
`
`
`
`nesses, or specific types of government institutions. The rea-
`
`
`
`
`
`
`
`
`sons for monitoring and controlling institutional telephone
`
`
`
`
`
`
`systems are evident. To prevent such institutions from incur-
`
`
`
`
`
`
`
`
`ring unaccountable telephone costs,
`the institutions must
`
`
`
`
`
`
`
`either restrict access to outbound telephone lines or employ a
`
`
`
`
`
`
`
`
`
`telephone monitoring system to charge the responsible party
`
`
`
`
`
`
`
`
`for making the outbound communication. Otherwise, unac-
`
`
`
`
`
`
`countable telephone costs would severally hinder the avail-
`
`
`
`
`
`
`
`ability of the telephone systems in institutions.
`
`
`
`
`
`
`
`Therefore, it is imperative for many institutions to utilize a
`
`
`
`
`
`
`
`
`
`communication system that provides an accurate identifica-
`
`
`
`
`
`
`tion means for administrators to determine the individual
`
`
`
`
`
`
`
`responsible for each outbound telephone call. A communica-
`
`
`
`
`
`
`
`tion system must also provide a monitoring means for main-
`
`
`
`
`
`
`
`
`taining a useful record of the communication. Additionally,
`
`
`
`
`
`
`
`
`the system may include a means for restricting access or a
`
`
`
`
`
`
`
`
`
`
`means for providing options to particular users. Considering
`
`
`
`
`
`
`
`
`the number of users in a large institution, different payment
`
`
`
`
`
`
`
`
`
`methods available, and the excessive call volume at many
`
`
`
`
`
`
`
`
`
`institutions, it is evident that an effective telephone manage-
`
`
`
`
`
`
`
`
`ment system is essential.
`
`
`
`
`Providing telephone systems in specific types of highly
`
`
`
`
`
`
`
`restricted institutions, such as in penal institutions, results in
`
`
`
`
`
`
`
`
`the consideration of numerous additional complicating fac-
`
`
`
`
`
`
`tors. Generally, outbound communication means in penal
`
`
`
`
`
`
`institutions are heavily regulated by the government. There-
`
`
`
`
`
`
`
`fore, communication systems implemented in penal institu-
`
`
`
`
`
`
`tions or similar facilities must meet greater security require-
`
`
`
`
`
`
`
`
`ments often mandated by regulatory bodies affiliated with the
`
`
`
`
`
`
`
`
`
`county, state, or federal institution. Thus, the communication
`
`
`
`
`
`
`
`
`system used in a regulated institution must employ unique
`
`
`
`
`
`
`
`
`functions.
`
`In its most general form, a penal institution’s telephone
`
`
`
`
`
`
`
`
`
`system utilizes a call processor to approve and place a call,
`
`
`
`
`
`
`
`
`
`
`surveillance equipment or monitoring equipment, and a
`
`
`
`
`
`
`
`recording device for evidencing the conversation. Generally,
`
`
`

`
`
`

`
`
`these simple systems are not equipped to restrict an inmate
`
`
`
`
`
`
`
`
`
`
`from calling any individual or to verify the identification of a
`
`
`
`
`
`
`
`
`
`
`user utilizing advanced authentication techniques. However,
`
`
`
`
`
`
`it is preferable for the call system devices now employed in
`
`
`
`
`
`
`
`
`
`
`
`such institutions to have the capability to thwart an inmate
`
`
`
`
`
`
`
`
`
`
`from calling certain specific individuals or types of individu-
`
`
`
`
`
`
`
`
`als. Without the necessary constraints on an inmate’s use of
`
`
`
`
`
`
`
`
`
`
`the telephone system, inmates have often harassed outside
`
`
`
`
`
`
`
`
`parties or individuals. For example, it is generally preferred
`
`
`
`
`
`
`
`
`
`that an inmate should not be able to place a telephone call to
`
`
`
`
`
`
`
`
`
`
`
`
`the prosecutor who prosecuted the inmate’s case or another
`
`
`
`
`
`
`
`
`
`attorney responsible for the sentencing of the inmate. In
`
`
`
`
`
`
`
`
`
`another example, it may be preferred that an inmate be pre-
`
`
`
`
`
`
`
`
`
`
`vented from contacting the victim of the inmate’s crime or
`
`
`
`
`
`
`
`
`
`witnesses from the inmate’s case. It has also been docu-
`
`
`
`
`
`
`
`
`
`mented that inmates have used previous penal institution call
`
`
`
`
`
`
`
`
`
`systems to perpetrate additional criminal activities such as
`
`
`
`
`
`
`
`
`fraudulent schemes or specific criminal conspiracies. Specifi-
`
`
`
`
`
`
`cally, inmates have been known to arrange credit card fraud
`
`
`
`
`
`
`
`
`
`
`attempts, the smuggling of contraband into the facility, and
`
`
`
`
`
`
`
`
`
`have even been known to arrange escape attempts over the
`
`
`
`
`
`
`
`
`
`
`penal institution’s telephone system. Therefore, it is critical
`
`
`
`
`
`
`
`
`in an efficient penal institution to carefully monitor all out-
`
`
`
`
`
`
`
`
`
`going telephone calls making a regulated penal institution
`
`
`
`
`
`
`
`telephone system a necessity.
`
`
`
`Another concern in implementing an efficient institution
`
`
`
`
`
`
`
`telephone system is cost control. In order for a system to be
`
`
`
`
`
`
`
`
`
`
`
`cost effective the system must critically monitor and record
`
`
`
`
`
`
`
`
`
`the activities of each individual user to properly charge each
`
`
`
`
`
`
`
`
`
`
`individual caller for his or her outgoing calls. Typically, tele-
`
`
`
`
`
`
`
`
`
`phone communication systems in penal institutions provide
`
`
`
`
`
`
`an inmate with a telephone account upon arrival. Each indi-
`
`
`
`
`
`
`
`
`vidual receives an account number. There are several options
`
`
`
`
`
`
`
`
`
`for an inmate to select with respect to payment on the account.
`
`
`
`
`
`
`
`
`
`
`
`
`For example, an inmate may place prior personal earnings
`
`
`
`
`
`
`
`
`
`into the account. The cost of each call is then deducted from
`
`
`
`
`
`
`
`
`
`
`
`
`the total amount in the inmate’s account until no balance
`
`
`
`
`
`
`
`
`
`
`remains. The inmate may choose to utilize collect call means.
`
`
`
`
`
`
`
`
`
`
`In addition, or alternatively, an inmate may be assigned a
`
`
`
`
`
`
`
`
`
`
`commissary account, where funds are added to the account
`
`
`
`
`
`
`
`
`
`based on work performed by the inmate. As the funds
`
`
`
`
`
`
`
`
`
`
`increase, the inmate may apply these funds to the cost of
`
`
`
`
`
`
`
`
`
`
`
`placing telephone calls. The inmate debit account may be
`
`
`
`
`
`
`
`
`
`located onsite, at a central office facility, or at a third-party
`
`
`
`
`
`
`
`
`
`
`
`site.
`
`The inmate debit account may alternatively be controlled
`
`
`
`
`
`
`
`
`by the inmate’ s family. For example, the inmate’ s family may
`
`
`
`
`
`
`
`
`
`
`control
`the inmate’s access to the debit account either
`
`
`
`
`
`
`
`
`
`remotely (e.g., by using the Internet, accessing a toll-free/pay
`
`
`
`
`
`
`
`
`to dial telephone number, using a mail form, etc.) or by
`
`
`
`
`
`
`
`
`
`
`
`visiting the prison facility. The inmate’s family may add
`
`
`
`
`
`
`
`
`
`funds to the debit account and thereby control the call volume
`
`
`
`
`
`
`
`
`
`
`
`allowed to the inmate.
`
`
`
`
`Another requirement of a secure telephone management
`
`
`
`
`
`
`system in a penal institution is the accurate identification of
`
`
`
`
`
`
`
`
`
`the telephone call participants. Generally, it is common in a
`
`
`
`
`
`
`
`
`
`penal institution to assign each inmate a personal identifica-
`
`
`
`
`
`
`
`tion number (PIN). When an inmate attempts to place a tele-
`
`
`
`
`
`
`
`
`
`phone call, the inmate must supply a valid PIN to gain access
`
`
`
`
`
`
`
`
`
`
`
`to the telephone system. However, a primary problem with
`
`
`
`
`
`
`
`
`
`this identification method is the ease of obtaining another
`
`
`
`
`
`
`
`
`
`inmate’s PIN. For example, individuals who commonly for-
`
`
`
`
`
`
`
`get their PIN may write it down, increasing the possibility that
`
`
`
`
`
`
`
`
`
`an unauthorized individual will view the PIN and use it. In
`
`
`
`
`
`
`
`
`
`
`addition, if a PIN number is compromised and utilized by an
`
`
`
`
`
`
`
`
`
`unauthorized inmate, the unauthorized inmate may then be
`
`
`
`
`
`
`
`able to call certain individuals who are restricted to that
`
`
`
`
`
`
`
`
`
`

`inmate, since the unauthorized inmate is no longer using the
`
`
`
`
`
`
`
`
`
`
`proper PIN associated with that inmate. In known systems,
`
`
`
`
`
`
`
`
`
`the PIN identification method is incapable of verifying that
`
`
`
`
`
`
`
`
`
`the individual who supplies the PIN is the actual specified
`
`
`
`
`
`
`
`
`
`
`inmate. Some systems have attempted to improve security by
`
`
`
`
`
`
`
`
`
`requiring the use of a debit card in conjunction with a PIN.
`
`
`
`
`
`
`
`
`
`
`The use ofthe debit card will only allow access to an inmate’ s
`
`
`
`
`
`
`
`
`
`
`
`
`
`account
`if the correct associated PIN is supplied. This
`
`
`
`
`
`
`
`
`
`method, however, provides only minimal additional protec-
`
`
`
`
`
`
`tion because a debit card and its associated PIN can often,
`
`
`
`
`
`
`
`
`
`
`
`with or without force, easily be taken from another inmate, or
`
`
`
`
`
`
`
`
`
`
`
`given to another inmate, especially in the violent atmosphere
`
`
`
`
`
`
`
`
`
`of a penal institution. For example, one inmate may threaten
`
`
`
`
`
`
`
`
`
`another inmate in order to obtain such information. Alterna-
`
`
`
`
`
`
`
`
`tively, one inmate may provide certain services in exchange
`
`
`
`
`
`
`
`
`
`for the use of another inmate’s telephone privileges. The
`
`
`
`
`
`
`
`
`
`possibility that two inmates will exchange accounts also
`
`
`
`
`
`
`
`
`exists, thereby allowing them to contact people that would
`
`
`
`
`
`
`
`
`
`normally be restricted to them.
`
`
`
`
`
`Further attempts to obviate security concerns include
`
`
`
`
`
`
`
`requiring personal information, in addition to a PIN, to be
`
`
`
`
`
`
`
`
`
`
`supplied by the inmate/user. For example, a user might be
`
`
`
`
`
`
`
`
`
`
`prompted to supply a PIN as well as certain information that
`
`
`
`
`
`
`
`
`
`
`may only be known to the user. A common example is a
`
`
`
`
`
`
`
`
`
`
`
`
`request by the call system to provide their mother’s maiden
`
`
`
`
`
`
`
`
`
`
`name. This provides an additional security measure, but again
`
`
`
`
`
`
`
`
`
`is minimally secure because such information can easily be
`
`
`
`
`
`
`
`
`
`obtained in a correctional facility. It would therefore be desir-
`
`
`
`
`
`
`
`
`able to develop a telephone management system that incor-
`
`
`
`
`
`
`
`
`porates an improved method of identification and/or verifica-
`
`
`
`
`
`
`
`tion.
`
`Another required feature of a telephone management sys-
`
`
`
`
`
`
`tem for a penal institution or similar facility is a means for
`
`
`
`
`
`
`
`
`
`
`
`
`restricting calls placed by a user (e.g., an inmate). It is well
`
`
`
`
`
`
`
`
`
`
`
`documented that
`inmates often try to harass individuals
`
`
`
`
`
`
`
`
`related to their arrest or confinement, such as judges, pros-
`
`
`
`
`
`
`
`
`
`ecutors or witnesses, etc., through telephonic communica-
`
`
`
`
`
`
`tions. Penal institutions have attempted to prevent this by
`
`
`
`
`
`
`
`
`
`restricting the telephone numbers each inmate is able to
`
`
`
`
`
`
`
`
`
`access. For example, a system may utilize a PIN or other
`
`
`
`
`
`
`
`
`
`
`
`identification means to access a list oftelephone numbers that
`
`
`
`
`
`
`
`
`
`the inmate may not call, or alternatively, the system may
`
`
`
`
`
`
`
`
`
`
`access a list of numbers that the inmate is authorized to
`
`
`
`
`
`
`
`
`
`
`
`connect to (i.e., the inmate can only call the numbers appear-
`
`
`
`
`
`
`
`
`
`
`ing on the list). Telephone numbers placed on the restricted
`
`
`
`
`
`
`
`
`
`
`list can include any individual related to the conviction (e.g.,
`
`
`
`
`
`
`
`
`
`
`the arresting police officer, the prosecuting attorney, etc.),
`
`
`
`
`
`
`
`
`while telephone numbers placed on the permitted list may be,
`
`
`
`
`
`
`
`
`
`
`for example, close family relatives. The system may also limit
`
`
`
`
`
`
`
`
`
`
`the amount of time each inmate/user is permitted to conduct
`
`
`
`
`
`
`
`
`
`
`each outbound telephone call through the system. Further-
`
`
`
`
`
`
`
`more, restrictions may be regularly updated. For example, if
`
`
`
`
`
`
`
`
`
`an inmate misbehaves, the inmate’s telephone privileges may
`
`
`
`
`
`
`
`
`be further limited or revoked completely.
`
`
`
`
`
`
`Penal institutions are also concerned with monitoring the
`
`
`
`
`
`
`
`activities and communications of inmates. Monitoring tele-
`
`
`
`
`
`
`phone activities is necessary to restrict connections to illegal
`
`
`
`
`
`
`
`
`activities outside of the institution.
`
`
`
`
`
`Three existing types of call monitoring techniques are
`
`
`
`
`
`
`
`
`known in the art. The first technique is live monitoring. Live
`
`
`
`
`
`
`
`
`
`
`
`monitoring requires an operator or other individual to listen to
`
`
`
`
`
`
`
`
`
`
`each telephone call and alert the proper authorities if neces-
`
`
`
`
`
`
`
`
`
`sary.
`
`The second type of monitoring involves recording the tele-
`
`
`
`
`
`
`
`
`phone conversation via a common recording device. A com-
`
`
`
`
`
`
`
`mon example of this is a recording device such as a magnetic
`
`
`
`
`
`
`
`

`
`
`tape drive. This type of monitoring may be continuous or
`
`
`
`
`
`
`
`
`
`
`intermittent depending on the degree of security required for
`
`
`
`
`
`
`
`
`
`each inmate.
`
`
`The third type of monitoring is known as passive monitor-
`
`
`
`
`
`
`
`
`
`ing. Passive monitoring may be activated when certain key-
`
`
`
`
`
`
`
`
`words are spoken. In addition, passive monitoring may be
`
`
`
`
`
`
`
`
`activated if the telephone call at the termination end is trans-
`
`
`
`
`
`
`
`
`
`
`ferred to a third party via certain known detection means such
`
`
`
`
`
`
`
`
`
`as “click and pop” detection, etc.
`
`
`
`
`
`
`Penal institutions currently record most inmate telephone
`
`
`
`
`
`
`
`calls, with the exception of lawyer-inmate communications
`
`
`
`
`
`
`
`which are generally prohibited by law. Typically in the art,
`
`
`
`
`
`
`
`
`
`
`monitoring may occur using any combination of the three
`
`
`
`
`
`
`
`
`
`methods (e.g., live monitoring, electronic recording monitor-
`
`
`
`
`
`
`ing, or passive monitoring). However, it would be desirable
`
`
`
`
`
`
`
`
`
`for a telephone management system to embody a means for
`
`
`
`
`
`
`
`
`
`determining which level of telephone monitoring should be
`
`
`
`
`
`
`
`
`employed for each telephone call. For example, it would be
`
`
`
`
`
`
`
`
`
`
`advantageous to flag certain individuals in an inmate’s profile
`
`
`
`
`
`
`
`
`
`as highly suspicious. If the inmate initiates communication
`
`
`
`
`
`
`
`
`with the flagged individual, the system will alert a live opera-
`
`
`
`
`
`
`
`
`
`tor to monitor the system. In such a system it is essential that
`
`
`
`
`
`
`
`
`
`
`
`the system correctly identify the called individual to avoid
`
`
`
`
`
`
`
`
`unnecessary expenditure of live operators.
`
`
`
`
`
`Alternatively, the inmate telephone call system may utilize
`
`
`
`
`
`
`
`a remote alert notification system wherein the system con-
`
`
`
`
`
`
`
`
`tacts an operator when a violation has occurred. The system
`
`
`
`
`
`
`
`
`
`may contact the operator utilizing telephone means, paging
`
`
`
`
`
`
`
`
`means, etc. This notification system may be set to call the
`
`
`
`
`
`
`
`
`
`
`
`operator a limited number of times or until the alert has been
`
`
`
`
`
`
`
`
`
`
`
`noted in the inmate telephone call system. The operator may
`
`
`
`
`
`
`
`
`
`
`then access information about the alert remotely using the
`
`
`
`
`
`
`
`
`
`telephone, Internet, or any other such remote access means.
`
`
`
`
`
`
`
`
`
`In order to alleviate some of the problems and concerns
`
`
`
`
`
`
`
`
`
`discussed herein, many penal institutions have implemented
`
`
`
`
`
`
`these
`certain task-specific advanced systems. Generally,
`
`
`
`
`
`“advanced” systems known in the art comprise several fea-
`
`
`
`
`
`
`
`
`tures.
`
`For example, it is known in current systems to employ
`
`
`
`
`
`
`
`
`
`
`permanent call blocking. Specifically, it is known in the art to
`
`
`
`
`
`
`
`
`
`
`
`block an inmate or group of inmates from dialing certain
`
`
`
`
`
`
`
`
`
`
`telephone numbers. Most systems also prevent inmates from
`
`
`
`
`
`
`
`
`talking directly to live operators. This prevents inmates from
`
`
`
`
`
`
`
`
`
`requesting that the operator forward a call or provide addi-
`
`
`
`
`
`
`
`
`
`tional telephone numbers allowing the inmates to harass or
`
`
`
`
`
`
`
`
`
`locate additional parties. Furthermore, current systems block
`
`
`
`
`
`
`
`“ l -800,” “ l -900” and other like telephone numbers including
`
`
`
`
`
`
`
`
`toll-free and pay-to-dial telephone numbers. In addition cer-
`
`
`
`
`
`
`
`tain institutions may elect to block country codes, specific
`
`
`
`
`
`
`
`
`area codes, or other third-party numbers.
`
`
`
`
`
`
`Current systems known in the art may also utilize a feature
`
`
`
`
`
`
`
`
`
`
`commonly referred to as “selective” call blocking. As dis-
`
`
`
`
`
`
`
`
`cussed, “selective” call blocking may be employed to thwart
`
`
`
`
`
`
`
`
`
`inmates from establishing a connection with a selected group
`
`
`
`
`
`
`
`of indi
