  • Copyright owners include entertainment and education service providers, such as music recording and software industry companies. Their products and/or services include music, music videos, movies, games, educational information, and other audio or video information applications. Each of these service providers distribute a combination of audio and/or video, or other data through a network, including satellite, cable and networks such as the Internet, via one or more Internet Service Providers (ISPs).

  • U. S. Patent No. 4,972,471 incorporated herein by reference, describes a method of encoding a given recorded signal, made up of a host of frequencies, comprising modifying the recorded signal to selectively alter in a known manner a portion of the recorded signal to produce a machine recognizable start code.
  • the machine recognizable start code is generally imperceptible to normal human recognition when the recorded signal is played in its intended manner.
  • Prior Art Figure 2 which gives an overall view of the method of encoding, the audio signal 10 is processed through a filter and certain scanning frequencies 11 are separated from the signal for separate processing.
  • the scanning frequencies 11 first undergo a review 12 to locate a proper location within the signal to be encoded by placing of a start code.
  • the audio signal is replayed, and at the appropriate location, the start code is introduced by means of a device 13. Digitizing of the signal is carried out at 14 and provides a recognizable fingerprint 16. Thus, in recording of the signal, a "fingerprint" is generated, a start code is introduced into the audio signal, and the signal is recorded at 18. The processing of the scanning frequencies introduces a certain fixed delay which is compensated for by delaying of the other frequencies at device 20.
  • a sequence of code symbols to be embedded in an audio signal is derived as the output of an Error Control Encoder 25.
  • the resulting sequence of code symbols is further encoded by means of a Spread Spectra Modulator 26 to produce a code signal that represents the sequence of code symbols.
  • the code signal is then modified by means of a Code Signal Shaper 27 to produce a modified code signal with frequency component levels.
  • the dynamically modified code signal is then combined with the original audio signal by means of a Signal Combiner 28 to produce a composite audio signal, which is then recorded on a recording medium, such as a DAT, or is otherwise subjected to a transmission channel.

  • the composite signal may be transmitted over a communication network, such as the Internet, other networks, or intranets.
  • encoding may be accomplished by adding an authorization usage header, of specified length, at the beginning of each digital or analog master tape or digital stream.

  • each optionally coded signal which is modified or applied to the content of an original audio signal, satisfy certain threshold criterion; namely that code modification occurs in a manner that does not impair the intended quality of the signal; that the resulting composite signal is inaudible, distinctive, not easily erased or deleted, and is easily recoverable.
  • This criterion applies to alternative embodiments of the invention in which a media or electronic file may contain, in addition to an audio data signal, one or more video signals (e.g., movies, music videos, etc.).
  • the encoding process will occur before the final product or media (e.g., a music CD, music video, movie video, or an electronic file of the above, etc.) is mass produced and distributed.
  • a record manufacturing company produces and distributes the media, such as music CDs, to, for example, Internet Service Providers, (ISPs), or other network service providers, who copy the data, such as music, onto their web site 56.
  • ISPs Internet Service Providers
  • music copied from each authorized CD is accessible on the Internet 57.
  • an ISP is provided with computer software that is capable of proactively monitoring music being accessed on the Internet.
  • This encrypted software which is essential for user access to the music file supplied to the user, contains a monitoring mechanism for determining the types of uses, such as whether a user is listening, recording or copying music.
  • the software monitors music use by looking at the Internet flag authorization level of each user and permitting only those activities a user's authorization level allows.
  • An ISP's software is capable of searching the Internet (including chat rooms, etc.) and detecting all data packets that contain predetermined data, such as music, and further contains an Internet authorization flag. Tracking is accomplished, for example, using a web crawler or manually at the ISP level. Other techniques may also be used.
  • a search detects the predetermined data that does not contain an Internet authorization flag, one of two scenarios may occur: (1 ) a report would be issued indicating the location of unauthorized use, such as the domain server address, a user's modem telephone number, the user's home or other unique identification; or (2) some specific action may be taken.
  • decryption is required, using conventional techniques.
  • One conventional decryption technique is to transmit each audio signal with some form of a header. Once the signal is decrypted, then a determination can be made whether the music is authorized.
  • a user or receiving party desiring to access music over the world wide web will access an authorized broker or ISP domain site 56 on the Internet. That is, a legitimate chain of use begins with an Internet Service Provider or broker 59 that is authorized to provide certain music on the Internet, and for which a royalty is paid according to the number of hits that the ISP/broker receives for the music. On the receiving end, the amount of royalty a user pays when accessing music from an authorized ISP or broker 59 could be dependent on the level of authorization that a user desires. While the above discussion has discussed an example where the predetermined data comprises music, other types of data may also be used.
  • an Internet or content authorization flag contains differing values, reflecting varying levels of authorization.
  • Each level of authorization essentially dictates specified Internet or network uses of a musical recording or other predetermined data, such as whether a user could listen to the music, copy the music, or how many multiple copies can be made.
  • a basic mechanism of one embodiment, at the recipient's end, is encryption of the file and payment mechanisms that unlocks the file and enables a user to do certain things with the data or music. Encryption mechanisms will control whether a user is granted access to the music file. Payment mechanisms will control hat type of access is permitted, such as whether a user may listen only to the music, or whether a user may copy music to the Internet, to a local computer, or to a local area network.
  • Encryption and payment mechanisms on the Internet are well known.
  • Internet uses may include 'listens once', 'listens twice', 'do not copy', 'copy once', 'copy twice', 'copy thrice', 'multiple listeners', 'download', 'distribute', etc.
  • One level of authorization may allow a user to pay one rate for just listening.
  • Another level of authorization may control the number of copies a user can make of a musical recording.
  • One basic mechanism for allowing copy control involves incorporating a counter into the ISP-provided software, which does the certification process of verifying each user and verifying that payment was made.
  • the software counter inspects that part of the encryption zone and verifies that payment was received for one copy and that one copy was made. Once this information is verified, the software prevents a user from making additional unauthorized copies of that music. Additionally, the software may be tamper-resistant such that breaches to the software is detectable.
  • Another usefulness of embedding Internet authorization flag is the ability to track distribution of music on the Internet.
  • the application of a coded identification signal, via the Internet authorization flag, to the genuine content of an original recording serves to establish its source and ownership. Since each original recording is embedded with such an Internet authorization flag, a search for the flag's existence would provide an important legal or other tracing 'hit' when a user accesses an Internet Service Provider's web site 56 and downloads the information, for instance. Thus, Internet tracking is triggered when a 'hit' occurs via a hot link.
  • the Internet authorization flag may be used in combination with a copyright flag, which may also be embedded in an original audio signal.
  • a copyright flag which may also be embedded in an original audio signal.
  • both copyright and Internet authorization flags can be embedded signals.
  • each musical recording will contain both flags, or at least an Internet authorization flag, at the time the musical recording is uploaded onto the Internet for transmission.
  • the copyright flag does not provide any information as to use of the copyrighted work. It merely indicates that the music is a copyrighted work.
  • an Internet flag basically indicates that a user is licensed to place, access and/or transmit an original musical recording on the Internet in a predetermined manner.
  • a user who receives a musical recording containing an Internet authorization flag could receive a special tape or CD from the recording company through the mail.
  • This tape or CD would be configured differently from other tapes or CD's sold in retail stores, because the user would be told that the tape or CD contains special flags for Internet use, making the user an authorized Internet user. Consequently, the user would be allowed to place the music on the Internet by the existence of the Internet authorization flag embedded in the musical recording, and by the use of the special CD configured to allow specified uses (i.e. copying) from/to the Internet.

Abstract

La présente invention concerne un système d'autorisation d'accès à Internet ou à un contenu quelconque. Ledit système fournit un avis d'autorisation d'accès à Internet qui se présente sous la forme d'un indicateur. Ledit indicateur peut être intégré à chaque enregistrement original au moment de sa création, de telle sorte que le système d'identification a pour objectif principal d'empêcher l'accès à Internet et l'utilisation non-autorisée d'un quelconque enregistrement original ne contenant pas un indicateur d'autorisation d'accès à Internet. L'indicateur d'autorisation d'accès à Internet peut être enregistré sur des supports, tels que des bandes audionumériques (BANs), des disques compacts (CDs), des vidéodisques numériques (DVDs), et des ordinateurs personnels (PCs), ou soumis à un canal ou un réseau de transmission, tel que satellite, câble, Internet ou intranets. Le système d'indication d'avis d'autorisation d'accès à Internet permet de contrôler différentes sortes d'éventuelles utilisations autorisées d'Internet, et peut identifier l'existence et l'emplacement d'une utilisation d'Internet non-autorisée.
