Description
Distribution of Digital Content in Mobile Computing Environments
Field of the Invention
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.
Definitions throughout this specification
The term "document" is to be taken as referring to any digital content, including but not limited to text, pictures, audio and video.
Reference to related applications
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").
Background to the invention
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.
Another problem with the present model of electronic document delivery is that the sender has to assume that the recipient has the necessary software to work on the document. This delivery model has proved to be problematic, as recipients often do not have the correct software, release version, or installation settings. The technique of including some software in documents, such as embedding Java scripts in HTML
pages and adding macros to Microsoft Office documents, provide only a partial solution.
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. Moreover, the sender's right can be safeguarded through the computing environment, which can enforce usage controls and implement flexible charging models.
Currently, the standard mechanism to protect a digital document is to encrypt it, so that only authorized users with the correct key can decrypt the document. Examples are PostX, DocSpace, and Marimba's DocService. This mechanism can be complemented with usage control features, as done by Tumbleweed and CertifiedMail.com. These solutions do not solve the problem of the recipient not having correct software or configuration settings to operate the document.
Another popular technique for protecting digital documents is through watermarking. A document can be watermarked with the owner's information. The document can further be watermarked with users' information to establish a usage trail. However, 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.
Consideration of the prior art
Interleaf, Inc. 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. Like the present invention, Interleaf provides a mechanism for bundling accompanying software for manipulating a document, e.g. decompression, GUI appearance. However, the present invention goes a step further by providing an environment within which the software and document are to be operated. Some resulting advantages include the ability to mask off any conflicting configurations and software on the native
machine, and to determine what resources are available, for instance for usage controls.

Description of drawings
In order that the invention may be fully understood and readily put into practical effect, a preferred embodiment will now be described with reference to the accompanying drawings in which:
Figure 1 is an illustration of the system architecture; and Figure 2 is a preferred flow chart.
Description of preferred embodiment
In the earlier applications there is detailed a mechanism for loading a mobile computing environment onto a machine for configuration, such as setting environment variables, loading data and installing software, then unloading the computing environment with all the configuration for subsequent recreation, either
on the same or another machine. The present invention makes use of this mechanism.
In a preferred embodiment of the present invention, pre-configured computing environments are registered on the sender's machine for operating various types of files. Each computing environment contains the software, fonts, environment settings and so forth that are needed to open the associated file category. A computing environment may also include other useful resources, like reference materials, backup utilities and (network) printers at a professional printing shop.
When the sender creates a new document, the operating system on his machine automatically loads the computing environment that is associated with the category of the new document. This is followed by the creation and opening of the new document using the appropriate software.
Besides creating the document using the software and tools in the computing environment, the sender can also customize the computing environment itself. This could include but are not limited to installing additional software, and masking off certain local resources, such as the floppy drive and local printers, so that they will not be available when the computing environment is recreated on the recipient's machine. Moreover, the sender can specify usage control requirements. These requirements could include, but are not limited to, a embedded usage counter, a notification being sent to a tracking agent each time the document is opened, or an authorization from an approval authority before the document can be opened.
Finally, the sender invokes a mechanism to unload the computing environment with all its contents and save it as image data. The image data can now be sent to the recipient, either on a physical medium such as CD-ROM, or via online transmission.
The sender can distribute a document, with accompanying software and usage control, in a disposable operating environment. Also, the operating environment can be clean and free of defects and/or viruses.
At the recipient's end, a standard loader is needed on his machine to reconstruct the computing environment from its image data. When the computing environment is recreated, it takes over the recipient's machine, so that resources within the computing environment are available to the recipient. The computing environment also carries out the usage control and resource masking measures specified by the sender. Finally, the target document is opened with the appropriate software. The recipient can operate the digital content using the accompanying software, and use all the resources in the provided accompanying environment.
In another preferred embodiment, the sender selects a pre-existing document, which causes the associated computing environment to be loaded, followed by the opening of the selected document using the appropriate software.
In a third preferred embodiment, the sender starts by selecting a computing environment directly. Once the selected computing environment is loaded, he then proceeds to invoke the appropriate software to create or import the document.
To now refer to the drawings, Figure 1 shows the system architecture. A sender client machine 10 can send a digital document with its computing environment to a recipient client machine 40, via sender server machine 20 and recipient server machine 30.
It is shown in Figure 2, the sender specifies the new document type, and the computing environment which is registered to handle documents of the type requested is then downloaded from the sender's server 20 to the sender's machine 10.
After the sender 10 creates the document, the sender 10 can then do one or more of:
(i) modify the document;
(ii) customize the computing environment such as, for example, by installing additional software, mask off local resources, and so forth; and (iii) specify usage requirements such as, for example, usage counter, usage tracking, runtime authorizations, and so forth, following which the sender 10 saves the computing environment (including document) on the server 20. The computing environment is then sent from sender server 20 to recipient server 30. The recipient 40 can then load the computing environment from the server 30.
At this time the computing environment:
(i) verifies that the internal usage counter is not exceeded; and/or (ii) reports usage to server 20; and/or (iii) obtains authorization from server 20; and/or
(iv) masks applications in recipient machine 40 so that only the computing environment is used by recipient 40.
The recipient 40 can then use the document in the computing environment.
Whilst there has been described in the foregoing description a preferred embodiment of the present invention, it will be understood by those skilled in the technology that many variations or modifications may be made without departing from the present invention.
