Definitions

  • the invention relates to a system for retrieving and transmitting information, comprising at least one telecommunication network having a first access point to the at least one telecommunication network for setting up, by an intended user of information, a first link with a first information provider, the first provider comprising a verification system for testing a property of the intended user against a predetermined criterion, with, in the event of a positive verification result, the first information provider supplying first information to the intended user.
  • Such a system is generally known, particularly in countries where information providers, on the grounds of government instructions, inter alia, are committed to take measures to achieve that specific information distributed by them can only be received by well-defined categories of users.
  • information providers on the grounds of government instructions, inter alia, are committed to take measures to achieve that specific information distributed by them can only be received by well-defined categories of users.
  • an information provider in this connection is understood to mean: an organisation or system which may forward information to human users.
  • the term information should be associated not only with factual information, but also with images, sounds and the like having a recreational and/or aesthetic nature, such as film images or music .
  • the information provider may comprise a system which, on the basis of characteristics of the voice of the intended user, may determine whether the age of said intended user lies above a predetermined threshold value.
  • a positive verification result i.e., if the user indeed has the required minimum age, the information requested is provided.
  • Dr Ingo R. Titze describes, e.g., that the fundamental frequency of the human voice, particularly during the first 20 years of life, decreases with age in such a manner that it may be reliably deduced from this whether a test subject has an age below or above a specific value.
  • Such a system has the drawback, inter alia, that each information provider who wants to distribute information among a limited target group in this way, should dispose of a verification system.
  • a monitoring organisation e.g., a government agency, must individually verify, for each information provider of the group referred to here, whether the verification system used complies with the specifications imposed.
  • a system according to the invention is characterised in that the first information comprises an access code for accessing second information with a second provider by way of a second access point and a second link, the first and second access points being allowed to be the same.
  • the first information provider is an issuer of access codes, disposing of an advanced and reliable verification system, while the second information provider need check only the access code attributed to the intended user for validity and possibly for the correspondence with an additional characteristic of the intended user, laid down during the retrieval of his access code.
  • the latter corresponds to the well-known access check with a user's name and a password.
  • the second information provider therefore, need not dispose of a verification system himself .
  • the information desired by the intended user is transmitted to the latter by the second information provider.
  • the link with the first information provider may be set up by way of the most elementary telecommunication network, e.g., a voice link by way of the public telephone network, while the link with the second information provider may be (partially) set up by way of a multimedia network, such as the Internet.
  • the information desired by the intended user may then have the form of a multimedia presentation, and therefore comprise, apart from sound, pictures as well, whether moving or not.
  • the system is characterised in that the verification system is arranged for determining whether the age of the intended user lies above a predetermined threshold value.
  • the system is characterised in that the first link 150 is a voice link and the verification system determines whether the age of the intended user lies above a predetermined threshold value on the basis of characteristics of the intended user's voice.
  • This form of age verification may be carried out relatively simply and without too much intervening in the personal privacy.
  • the system is characterised in that the first link is a voice link and the verification system requests the intended user to pronounce a word not known in advance, or a series of sounds not known in advance, whereafter the verification system determines whether the word pronounced, or the series of sounds pronounced, corresponds to the word or the series of sounds requested, and whether the age of the intended user lies above a threshold value predetermined on the basis of characteristics of the intended user's voice.
  • the verification system it is virtually impossible to lead the verification system astray by utilising prerecorded speech fragments .
  • the system is characterised in that the first access point provides access to a first telecommunication network and the second access point provides access to a second telecommunication network.
  • the first telecommunication network may be, e.g. , the public telephone network
  • the second telecommunication network may be a multimedia network, such as the Internet .
  • Said embodiment may be applied when there is a need to carry out the verification at another point in time, and with simpler means, than retrieving information.
  • An alternative is carrying out the verification by way of the same network as retrieving, e.g., by building in the verification option into the web browser with which the multimedia network is approached.
  • the system is characterised in that the first link is a voice link and providing the first information takes place by transmitting voice signals.
  • the access code is supplied to the intended user in the form of one or more words or series of sounds generated, e.g., by a voice-synthesis system.
  • the system is characterised in that, in the event of a positive verification result, there is laid down an additional characteristic of the intended user by the first information provider, coupled to the access code supplied.
  • additional characteristic may be, e.g., a name utilised by the intended user, or a number, established by the first information provider, of the connection from where the first link is set up. This makes possible an additional protection against fraud by way of access codes .
  • the system is characterised in that the system comprises means with which the first information provider communicates the additional characteristic of the intended user to the second information provider, together with the access code supplied to said intended user. Said provision makes it possible not only to keep a check in hindsight on the use of issued access codes, but to carry out said check of an access code during the validity investigation by the second information provider already.
  • FIG. 1 schematically shows an overview of a system according to the invention, in which, for the first link and for the second link, there is consecutively made use of two networks possibly differing in properties.
  • the digit 1 denotes the user who wants to retrieve information from information provider 5.
  • user 1 contacts information provider 2 by way of telecommunication network 3 ; the data for this purpose he was able to derive from a communication in a daily newspaper or a periodical, or he acquired it from an Internet session.
  • the information provider 2 preferably disposes of a "voice-response" system by which user 1 is requested to answer one or more questions.
  • the voice signals reaching the information provider 2 by way of the telecommunication network 3 are analysed by a verification system available within the information provider 2.
  • a predetermined criterion e.g., whether user 1 has at least reached a specific age. Should user 1 comply with this (a positive verification result) , then information provider 2 communicates an access code to user 1, in this example in spoken form.
  • the user 1 subsequently breaks off the link by way of telecommunication network 3 and sets up a new link with information provider 5 by way of multimedia network 4.
  • an access code in this example he keys in the access code received in advance from information provider 2. If the keyed-in [?] code is valid, information provider 5 then transmits the desired information to user 1 by way of the multimedia network 4.
  • a link 6 optionally present between information providers 2 and 5.
  • information provider 2 may communicate an additional characteristic of user 1 to information provider 5, in such a manner that the latter may check whether the access code keyed in by user 1 corresponds to said additional characteristic.
  • the additional characteristic may be, e.g., the number of the connection from where user 1 contacted information provider 2.
  • This has the advantage that the access code communicated to user 1 may only be used from the connecting number laid down therewith. This renders "trade in access codes" less attractive.
  • a further measure, which may be taken to reduce the chance of fraud, lies in validating access codes supplied for a limited period of time. Variants of the embodiment sketched here may be imagined without detracting from the basic principle of the invention. Thus, it is possible that no use is made of two separate telecommunication networks, but that networks 3 and 4 coincide. In this case, the access to the provider of access codes may also be afforded by way of the web browser, loaded into the PC of user 1, with which the latter approaches the multimedia network.
