Definitions

  • This invention relates to a technique of anonymous communication over a public telephone network. More particularly this invention relates to a technique for reestablishing anonymous telephone communication between parties who have previously communicated anonymously using another technique.
  • U.S. Patent No. 5,818,836 proposes an anonymous voice sys- tern which can establish an anonymous telephone communication through a circuit switched network (CSN) .
  • CSN circuit switched network
  • two parties place separate telephone calls to the anonymous voice system through the CSN.
  • the parties then enter matchcodes through their telephone keypads.
  • the anonymous voice system compares the matchcodes entered by the parties and connects the telephone calls if the matchcodes match.
  • the system may include an on-line data service that establishes electronic communication between the parties through corresponding data terminals.
  • the data terminals may have resident anonymous voice input commands that can be selected by the parties.
  • the on-line data service transmits a connect command to the anonymous voice system which dials the two parties, or waits for the parties to dial the system, and then connects the parties.
  • the system also stores a couple record during the first anonymous call recording the matchcode and the telephone numbers of both parties .
  • This system is not easily scalable to mass use by internet participants. Its reliance upon the participants to select a matchcode virtually guarantees matchcode conflicts, and risks a r ⁇ isconnection.
  • the system attempts to reduce this risk by relying on automatic number identification (ANI) to obtain the caller's telephone number.
  • ANI automatic number identification
  • the participants are identified using both the chosen matchcode and the ANI.
  • This arrangement requires a record of the participants' telephone numbers to be maintained, and telephone access to the system is limited to the particular telephone numbers which were used to create the system's database entries. If multiple parties are involved, then each must return to the telephone which was entered into the system's database record before a connection can be established.
  • the telephones must all be identifiable using ANI, which is not universal. For example a subscriber can disable the ANI feature from his telephone.
  • agent which provides a virtual telephone number switchboard service to the parties.
  • the agent is particularly adapted for use over a data network, which may be the Internet .
  • the agent provides software modules which can be integrated with web browsers and similar communication equipment.
  • One or all of the parties desiring to establish subsequent anonymous communication select a Virtual Tele ⁇ phone Number (VTN) icon on the web page of a chat site or on the browser which connects them to the chat server.
  • VTN Virtual Tele ⁇ phone Number
  • the chat server sends a request to a VTN server for a VTN "box number", which is analogous to a telephone extension number.
  • the VTN server generates a single-use VTN box number, which is not currently in use in the VTN system.
  • the sin- gle-use VTN box number is stored within the VTN server's switchboard database.
  • the VTN server provides all the chatters the telephone number of the VTN call center switchboard (the VTN PSTN) , and the single-use VTN box number for use upon reaching the switchboard.
  • the chatting parties may optionally disconnect from the internet chat server, and within a mutually agreed upon time window, call the VTN call center switchboard, and enter the single-use VTN box number.
  • the chatting parties may remain connected to the internet chat server, and continue their vocal conversation by internet-based vocal technologies, for example voice-over-IP.
  • the chatting parties can enter their single-use VTN box number by providing the information to a human operator, or preferably by keypad entry, using known tone-dial technology.
  • the VTN call center switchboard then connects all participants who entered the assigned single-use VTN box number on the same telephone line.
  • the box After the parties have disconnected from the VTN box number, the box is closed and deleted from the VTN server's switchboard database, and its space is released for formation of a new single-use VTN box number in order to service new participants. Moreover, if there is no entry to the VTN box, it will be automatically deleted after a predetermined time-out interval.
  • the VTN call center switchboard may have many open boxes at a given time.
  • At least one of the chat participants subscribes to the virtual telephone number service at a VTN web site by providing an actual telephone number (PSTN or MP) , but does not provide any other personal details.
  • the subscriber receives a unique personal identification number (PIN) for identification when he uses the VTN service.
  • the subscriber may download client software to his personal computer, which includes a PIN.
  • the PIN is automatically transmitted to the VTN server whenever he engages the VTN icon in his internet browser or on the web page of the chat site.
  • the VTN server and VTN call center switchboard can be located in a common telephone center, or can be geographically distributed in many telephone centers under central synchronization control. They can also be located at the site of the chat server, or within public telecommunica- tions systems.
  • a first chatter who has previously subscribed to the VTN service, may receive the single-use VTN box number and the telephone number of the VTN call center switchboard, and co - municate these to a second chatter manually, or via the chatting server.
  • the second chatter then accesses the VTN call center switchboard and enters the single-use VTN box number.
  • the VTN call center switchboard looks up the actual telephone number of the first chatter, and establishes an active tele- phone connection between the two chatters. Neither the subscriber nor the second chatter, who need not be a subscriber, has revealed his telephone number to the other. Subsequent telephonic sessions can be established between the two chatters by repeating the above-described procedure, using a new single-use VTN box number.
  • the VTN call center switchboard calls the participants. Prior to their usage of the system, the participants must register and provide some information, for example their actual telephone numbers. They then receive a password and PIN number. After they schedule a meeting with one another as described above, companion, they both engage an icon on the chat site web page, or their internet browsers, after which they are each requested them to enter their respective passwords and PIN numbers.
  • the VTN call center switchboard then calls each of them at their pre-registered telephone number and establishes a connection between the two telephone lines. The connection can be established immediately, or at a scheduled time.
  • a first party participant who has previously subscribed to VTN services in the manner given above, contacts the VTN call center switchboard.
  • a first party may desire to sell his car, but does not wish to reveal his actual telephone number.
  • the first party contacts the VTN call center switchboard by any suitable method, identifies himself using his password and PIN, and requests a code identifier.
  • the first party publicizes the code and invites offers .
  • the call is forwarded to the pre-registered telephone number of the first party.
  • the first party can define conditions for the telephone connection, for example permissible times for receiving forwarded telephone calls from the second party.
  • a plurality of partici- pants call a telephone community, which is realized as a central telephone switchboard.
  • the participants are presented with a list of currently available chat rooms, each dealing with an assigned topic.
  • chat rooms can be created, either by the community administration, or by chatters themselves.
  • the switchboard is accessible by normal telephonic communication, or via an internet VTN web site.
  • Currently available chat rooms are made known by any public medium, e.g., television, radio, the community web sites, or other internet sites.
  • the geographical location of the community switch- boards may be presented.
  • the telephone chat room is open to a limited number of participants.
  • Supervision of the chat form is accomplished by a system administrator, which may be a human, or a computer-controlled device, following a set of predetermined rules.
  • the ad- ministrator may govern who will speak at a given moment, and for how long. Chatters may move among chat rooms as they wish, and may elect to chat privately with particular co-participants in the chat.

Abstract

Appareil (28) et procédé assurant un service de commutation à numéros de téléphone virtuels à deux parties (20, 22) désirant communiquer l'une avec l'autre de façon anonyme. Le service est particulièrement adapté à l'utilisation sur l'Internet. On peut télécharger des modules pouvant être intégrés à des navigateurs Web et des sites Web tel que des sites de bavardage-clavier. Un identificateur de transaction ou code d'appariement met en oeuvre un numéro de téléphone virtuel à l'attention des parties (20, 22); le service agit alors comme un agent pour faciliter le contact entre eux. Dans certains modes de fonctionnement, l'agent ne connaît pas les identités ou les numéros de téléphone réels des parties.
