Definitions

  • the present invention relates generally to the distribution of digital content, in which a mobile computing environment is provided within which it is possible to operate the digital content.
  • document is to be taken as referring to any digital content, including but not limited to text, pictures, audio and video.
  • the present invention is related to earlier Singapore patent applications numbers 20001262-5 and 20001263-3, and PCT/SG99/Q0037 the contents of which are hereby incorporated by reference (the "earlier applications").
  • Aberdeen's research (Securing the Gap Between E-Mail and E-Commerce, Aberdeen Group, July 9 1999) shows that businesses spend $300 billion annually on document delivery services such as certified mail, courier, overnight express, and facsimile transmission. Since 90% of business documents originate in electronic form, online distribution would be speedier and cheaper than sending documents manually. For example, UPS charges $2.50 for an electronic document up to 1.4 Mbytes in size, but $10 to deliver 20 pages overnight. As factors that contribute to success of physical delivery - track-ability, security, reliability - are quickly emerging as standards in electronic delivery, Aberdeen projects that 35% of the overnight delivery market, or 21 million documents per business day, will transition to the Internet by 2001.
  • a document can be delivered electronically in one of two formats - a published format, or the original format in which the document is created. If a published format (e.g. PDF) is used, the recipient would not be able to edit the document, and the sender would have no control over usage of the document. If the document is sent out in its original format, the sender still has no way of controlling usage.
  • a published format e.g. PDF
  • the present invention will address the shortcomings of the existing model by distributing a document within a computing environment that is configured to control and operate the document.
  • the recipient of the document need not have the correct software or fonts on their machine, as they are bundled in the accompanying computing environment.
  • the sender's right can be safeguarded through the computing environment, which can enforce usage controls and implement flexible charging models.
  • a document can be watermarked with the owner's information.
  • the document can further be watermarked with users' information to establish a usage trail.
  • watermarking allows only enforcement after the fact; it does not control the usage of the document, nor does watermarking address the necessity for the recipient to have the proper environment.
  • the present invention addresses both problems by distributing the document in a computing environment, which is configured to operate the document.
  • the invention complements, rather than replaces, the existing techniques described above.
  • WO00/02148 discloses a system and method for the "rendering and displaying of a document at a client system without requiring that any application specific software be installed on the client system."
  • a "compound document” is defined as a "self-contained document structure which has the capacity to include, in combination, text, graphics, and images". The documentation is described as including text, graphics and possibly images.
  • Page 10, line 1 et seq describes document downloading from server to client as including any applets (Java) associated with the documents including downloading applets to decompress received documents, scale documents, control GUI features and present features such as toolbars, history bars etc., (P.17 line 22 et seq.).
  • Interleaf does not go into detail regarding usage control except to say that some security is provided by not "storing" the document permanently on the client.
  • Interleaf provides a mechanism for bundling accompanying software for manipulating a document, e.g. decompression, GUI appearance.
  • the present invention goes a step further by providing an environment within which the software and document are to be operated.
  • Budge et al. 6,014,689 discloses a system in which video messages containing audio and video components and an attached player in an executable file are sent over conventional communications networks as an email, as described throughout the specification. When the recipient views the email, the file is executed and the audio/video message either uses the embedded player or a player resident on the viewer's machine.' Budge does not disclose any details regarding usage controls.
  • This patent provides a mechanism for bundling a player with video message in an executable file. Same distinction as with WO00/02148.
  • Venkatraman et al. 6,014,688 assigned to the PostX Corporation describes an email enhancement system in which software is embedded in an email in order for the recipient to view contents and perform the functional attributes that make up the email message.
  • This patent provides a mechanism for bundling software with an email. Same distinction as with WO00/02148.
  • Narasimhalu et al. 5,499,298 discloses controlling access and usage of digital information by incorporating usage history and allowable access into the digital content as described in col. 4, line 45 et seq. as including "use once" and "use-n- times” feature.
  • This patent provides a mechanism for embedding usage control information within digital content. The difference is that the present invention provides an operating environment as described above, as well as accompanying software.
  • Stefik 5,715,403 disclose a system for controlling the distribution and use of digital work having usage rights in which "right specification components" include time, control, copy count, access, and fee/incentives; with usage rights attached directly to digital works (col. 9, line 18 et seq.)
  • This patent provides a mechanism for embedding usage control information within digital content. The difference is that the present invention provides an operating environment as described above, as well as accompanying software.
  • Archibald et al. 5,825,883 is directed towards a system that accounts for usage of digital applications e.g. software application, video file, text file, image file, by embedding a "meter module" as shown in Figure 6, and described in Col. 10, line 57 et seq, as a means to control and monitor access and usage and bill accordingly.
  • This patent provides a system to account for usage of digital applications by embedding a meter module. Same distinction as with 5,499,298.
  • Wyman 5,745,879 discloses a system for managing execution of licensed programs in which the product use authorization may allow a variety of license alternatives such as “duration”, “context” (location and environment), consumption, etc. (Col. 10, line 42 et seq.).
  • This patent provides a system for managing execution of licensed software. Same distinction as with 5,499,298. Summary of invention
