BAKGROUND

Teletext services have been in commercial use fordecdes to display paged images of textural infoirnation to TV set-top boxes around the world. The idea was based around the notion of an onliranewspaper. Teletext has the electronic advantage of updating its pages Eve as events unfold, with a far broader range of indexed topics on demand than traditional television news can delver Depit these advantages. Teletext has not become popular, lacking the richness of cantent types, navigability, search-abiity, Interactivity; variety, capacity and real of the Internet However as a publishing system, thelntemet only canme of ge when the Wod Wide Web was invented, whh embodied these characterIstics into a scrolling page and hyperlink paradigm. But for many commercial publishers, the World Wide Web has been financially dIastrous.

UnIke Telatext, which usually required a proprietary decoder to access, the Web diftWbutes Its Information by liberally sending eAsily Qecodable content soure fles to proxy servers and end users alike, This allows any recipient to make unptuotdzed duplicaios Consequengy, to avoid-the instant devaluation of contnt through unauthriZed republishing via newagroups, proxy aevers, email, pirate sites and the like, publishers have kept most of the Wodd's best content off the not, confining it to paper instead. As a resut, manyauthors COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:52 REDBANK MANOR PTY LTD 61397441788 Page 4 00 Oa2nnq 0 whose works have not been recognized as satisfying the economics of conventional paper publishing still remain unpublished.

A nurmber of approaches, to solving thesp problems have been based on the concept of allowing end-users to download an encrypted copy of the document and allowing access after a required royalty fee has been paid.

Unfortunately, hackers have thwarted many of these methbds by breaking into unprotected end-user program memory after the content has been decrypted.

As.a.result, s*stem8 based on downloading enprypted files have ribt gained wide publisher acceptacae, 00 o 10 Remote display protocols have been slowly developing the robustness Sand scalability rdired for the tirnsmlision of livecomputer .snft ihts over the Internet to big audiences. These protocols work by maintaining the end-user's application on a server, while ohly sending the orosen udates to an end users display. The screen image updates take comparatively little bandwidth to transmit,easily traversing a standard dialup modem Instead of needing thickcoaxal cable, as is the case with cable-TV. The success of these protocols is ahieved by avoiding where possible the sending of bulky pixel-forpixel or field-byfield pictures of screens from the srver to the endwuder, but instead sending compact graphics commands. These are able to rapidly mirror the fonts. and shapes on the end-usei'sdisplay.Mouseclicks and keysttokes are sent back to the server over the same.netwoC to'support end-iser interaction With the live screens. Examples of industy-standsi reMobte display protocols indude Qitrix ICA, Microsoft RDP and Unit-based X-i.

This leads to over-scrolling and subsequent scrolling back again, This effect is exacerbated When the Internet is accessed over cell phone or satellite networks, which being radio-based, may introduce additional roundtrip response delays of at least a second.

Clicks for scrolling can also cause problems at the server, as significant N computing power will be required to execute commands from hundreds of 00 0 10 simultaneous remote display users on the one machine. Indeed, depending on S the container application in which the document is being displayed, scrolling and iavigation may be impossible to achieve satisfactorily, with the application redrawing and thus resending the entire screen several times for each mouse click, slowing the user experience down to a crawl. Thus documents designed for the Web, for printing or in device independent formats such as Adobe Acrobat files may not work well unmodified if transmitted using rermote display protocols.

A significant inhibitor to the adoption of remote display protocols for Internet-style document image publishing has been cost It takes at least an order of magnitude more proessing power to support an end-uses remote graphical user interfacotin a server than Just sending them a simple Web page.

Additionally, many Web servers are downloaded free to the service provider, while remote dispay protocols and their operating systems, suitable for slow networks such as the Intemet, are typically quite expensive. This means that commercial online publishing cannot take place using remote display protocols unless the Interiet publisher's micropayments problem is addressed, This occurs when a document is worth less to the end user than the additional cost of a credit or bank transaction charge to the pubisher.

One answer has been for publishers to sell online subscriptions to a site instead of individual documents, with users consuming their deposited funds as documents are made availabte. This idea has three pritems: firstly, evsy publisher rust run their own secure billing and tracking systen, which represents a high barrier to entry for the world's 80,000 small publishers; Page COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:53 REDBANK MANOR PTY LTD 61397441788 Page 6 00 0 4 0 second-ly, evy pklisher wouldveno toI&iIJ trust to'sa sewuity and privacy Mweat pubiic, that they would not loose -their money or the privacy oftheir credit card. dpalls; tt.dlI, i on) erspr ,onywants tosee.,one document, the rest of their subscription i4 wased publisher big and triakin~g system, allowinig users topay a shngle enty for a ruMOnersal subscrIPton'.

Xerox Corporation has approached the problem of commercial online publishing by pmoosing, in essence, a softare photocopier. The idea appears to be for end users to use this software to reproduce content whereby such repiroductloni; are metered'for a~ccess by authoriz~cJ.pard .es and charged for accordingly. However, the content still becomes resident on a users machine and is therefore subject to unauthorized copying Nf the security pro tocols are eircumhvented.

Suitably the management subsystem resides on centralized server groups but the presentation subsystem may be distributed across many distributed servers.

The system may also include an interface subsystem that provides NO access for users to the electronic content and indicates any fees to be levied.

c- Suitably the system also includes a paynin subaystem that 00 intermediates payments between fee payers, fee receivers and one or more financial institutions or organisations maintaining accounts on behaf of others, in preferen--ce, Lhe inventlon may also include. one or miore stakeholder subsystems that.provide managemerit functions for authora, publishers, advertisers, dcvelipers, the operators of the system and other stakeholders.

Management functions include associating business models, comprising but not Ilmited to scripts, documents and data, Wielectronic content Business models are used to implement relationships between all the stakeholders and endusers. The stakeholder subsystems are suitably dishiblted across computers conWvnient to each stakeholder and are in communication With the management subsystem.

Electronic.content is preferably electronic do'unents but may also be video; audio, printer instricticns or other digil medi.

In a further form the invention resides in a method of securing electrdnic content including the steps of: storing the electronic content in a repository; associating business modeils with the electronic Content receiving a request from a user t view the electronic content; chedking business models associated with the electronic conatent for deteining i stCtl r ihfdomatin; csediting acouhts \ith fees adoording to th fee structure infomation; and presentg the electnic ontent to the use r via rene display protocols.

To assist in understanding the invention preferred embodiments will now t) be described with referenco to the following figures in which, FIG 1 displays an overview of the system; FIG 2 is ap overview of the managpment subsystem; O FIG3 is an overview of the presentation subsystem; ci FIG 4 is an overview of the stakeholder subsystemp 00 00 Fl .iG 5 is an overview of the 6b interfacte subsystem; FIG 6 is an overview of the payments subsystem; DETALED DESCRIPTIO OFTHE -DRA ING Referrig to FICI 1, there is shown an overview of the system for secure dIstribution of electronic ddocuments and for toWli'iif fees paid for content access. The sys6m iorinits of two core subsysteri and three supporting subsystems,. For hase of exlanation, the invention is described in terms of electronic documents but ii will be appr6cldated that it includes any form of electronic content.

The cor subsyistms are a ma inagerrent subsystem, and a presentation subsystem. These cr6 sub:ysthms are supporidt by stakeholder subsystem, a payments mhabsystem, and an interfc subsystem.

The Management subsystem integrates the operation of the other subsystems and manages access to the content. I a lo enforces the manner in which content may bo used.

Content may include text documents, images, advertising, applets or other material- The n stakeholder subsystem also associates business models (financial models and other information pertaining to the use and effect of a document). A Stakeholder subsystems also store master copies of a publisher's documents (current and previous) plus provides staging and assembly areas for future publication.

ON The Payments subsystem handles all aspects of payment for viewing of Cl content, including interfacing with financial institutions or other organisations for 00 payrment clearance. The subsystem deducts and makes payments under the Scontrol of the management subsystem.

The Interface subsystem provides hyperinks, prices, authentication and other information to Web pages, the Presentation subsystem and other information viewing systems, such as WAP servers. This enables content imaged by the invention to be advertised online.

The current embodiment of these subsystems may be used in the following publishing scenario: 1. Application service providers (ASPS) load the interface and presentation subsystems on their computer(s), connecting them to the management subsystem via virtual private network(s); 2. Stakeholders such as publishers, content creators, advertising executives, advertisers and developers use the stakeholder subsystem(s) to put their documents on a server, attaching pricing models etc to them plus their release dates and staging Instructions etc; 3. Publishers (or other stakeholders under certain circumstances) use the stakeholder subsystem(s) to nominate the ASPs they wish to image their content for thein or let the management subsystem allocate thse automatically; 4. The interface subsystems advertise documents or associated groups of documents by providing URLs (or other content pointers) and pricing information to publisher web sites etc; COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:54 REDBANK MANOR PTY LTD 61397441788 Page 12 00 i Users click on advertised fRLs, initiating an authentication session via the iterface subsystems;

C)

After uthentn tion;the management subsystems assess the users right and financial standing to se the desired document image ri relation to any associated business models; 7. If the user has the required access rights amd funds on hand, the IND ~presenttior. subystem 1is inade avilable to display the required documeht Image, if not the user i lead through the proe i of gaining 6css rights if so Slallowed by the asociated business miodels and supplying the required fumhds 00 through the payment subsystems; c] 8. The presentation subsystiem presis the requested document or choise of document within a group tf documents accbrdhing to the Conditions set by the stakeholders and as enforced by the manadnent substem; 9. As the image of a chosen document I being successfu y presented, accounts within the management ribsystem are being credited and deducted accordingly; The presentation subystem alows the User to search and navigate within a documenrt andri over the pubishers document image site or over multiple sites;:.

11. The presentatiori subsystem informs the management subsystem of document usage details, including advertising exposures etc; 12. Uis ry Search and view other document images as acccss rights aihd funds allow, being diveted to the apropi"ate areas if these are deficient 13. T e nent sbstesplits the revenues and expenses between ol the -thk a dng to tha&fin an in dels and which stak~hord e ornatiednii d ocumen accssed; 14.

Files contain encrypted cookies of information, using a position in a directory hierarchy to reflect the context in which the information was generated.

IO Processes act to summarise these files into meaningful reports, transferring them into compressed archives to save on disk space. These ci summaries may be presented to end-users in tabular form, suitable for use by a 00 0 10 spreadsheet or database program. Processes may be triggered at set times or o upon request, depending on the volume of files being handled and the timeliness of the information required.

Signals are files used to communicate messages or pass information between processs. The transmission of signals Is the responsibility of the messaging units. Ultimately, most signals will become files. For example, a signal sent by the presentation subsystem to the management subsystem may be unpacked and stored by the lafter tn a number of relevant directory hierarchies. Therefore signarling is also a bandwidth reductioh mechanism, as one -signel from a presentation subsystem may cause many reads or writes in the file hierarchies maintained by the Management system. Copies of selected reports, files or archived'files may then be aggregated into extracts, to be captured by database applications fordetailed off-line analysis.

SXML files and messaging units are used throughout the figures and description by way of example only. The system is not limited solely to XML Because this subsystem must eventually scale to handle millions of simultaneous users accessing millions of documents, information must be stored in a way closely resembling its intended use. In this way, processing will be reduced, saying money and increasing peformance. Therefore the same Information will often be stored in dfferent ways. This also allows verification by crosschecking plu application-leveldata redundancy, enabling robust disaster recovery, even from damaged backup media.

The display units interacting with end-users are hardened against denial 26 of service attacks. This is implemented by monitoring end-user activity, limiting the number of repeat operations for which no payment is require.d; Most database, authentication and die ig mechanistms designed for corporate use (such as Microsofts Active Directory, SQL Server and COM- Plus) do not perform well for more than 20,000 simultaneous users. A medium sized magazine, a typical publisher user, has 80,000 subscribers and there are around 144,000 magazines in the English-speaking world. The billing Aind trcking aspect of the managemnnt system must provide universal, publisher 'stable' and individual title subscription services for all of these. Therefore the Management and Stakeholder subsystems and messaging units are file-based for simplcity, with inbullt-loa4 balancing mechanisms.

These hlerar~tdes may also be further partitioned according to the logica groupings within them (aphbetially S and L-Z for example), as required. Thus. load balancng can be achleved using simple partitioning tchniques.

Thie basic layout 0 is then used by the formatting unit to measure and manipulate content---- O information pertaining to end-user interactions, such as document V' navigaton, is encrypted. This prevents unauthorized display units or external viewers from improperly accessing content. Documents may also be password protected to prevent opening by unauthorized display units or viewers.

I\D Using the current embodiment of the invention, the presentation O subsystem may be used in a commercial publishin environment in the 0C following manner: 00 Presentation subsystems are loaded on Application Service N Provider machines; 2. Publishers allow their content to be conhected to Application Service Providers running the Presentation Subsystems; 3. Stakeholder subsystems provide information to the interface subsystems, allowing links to the presentation subsystems to be published in Web pages or other browser display protocols such as WAP; 4. An end-user requests to see a document by clicking on a link; The interface subsystems forward locational information to the management subsystems; 20 6. A logon session is created (such as via a secure Web page or remote display protocols) to find out who the user is in relation to the publisher, which if successful, causes the management subsystem to create a unique session number for that user's session with the presentation subsystem; 7. The logon session forwards locational information to the Management subsystem;.

8. The display unit forwards locational information to the Management subsystems; 9, The display unit finds the document in the Cache unit; The caching unit may attempt to obtain the document from 3o .another's Presentation subsystem's cache COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:56 REDBANK MANOR PTY LTD 61397441788 Page 24 00 22 C 11 If the document is not in or found by the cache, the display unit obtains the document's location from the Management sub-system, allowing it CA to draw on the publisher's master document repository. If the Management CV) Subsystem is not aware of the document's. locatipn, the display unit forwards a request to the management subsystem to issue a new document ID to the document, which in most cases becomes its filename and path; the location of this newly named document is then sent back to the Presentation Subsystem; 0 12. Once the desired documents ilename has been established, the N' management subsystem evaluates the request, authorizing it ac6ording to the 00 10 business models ass-ciated with the document; C 13. Once authorized by the management subsystem, the display unit seeks a document from the cache corresponding or suitably sized to the display area, user and publisher preferences. If one can be found (the majority of caes), it is loaded and displayed for image trasmission, if nbt, the rendering unit is engaged to determine an appropriate layout and navigation system and the reformatting unit then handles the content accordingly; 14. The caching unit may attempt to obtain a suitable document from another's Presentation subsystem's cache, rather than initiate fresh reformatting.

15. After being loaded from the cache, the document image is displayed via remote display protocols; 16. The display unit accepts navigation commands from the user; 17. The display unit monitors end-user activity in relation to time or session charges as controlled by the management subsystem; 18. The display unit monitors 'revenue conten such as advertising, informing the management subsystem of its exposure; 19. The display unit also provides account management tools and activty reports to end users: The display unit also provides end-users inrated searching between sites, documents and the content within a document; COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:57 REDBANK MANOR PTY LTD 61397441788 Page 00 0 23 Cl 21. The display unit also provides histories of previously seen Sdocuments, favorites and 'to-do' lists of must-see documents; 22. The display unit also embodies the functions of the Interface subsystems, allowing further content to be viewed without leaving the remote display protocol environment.

-23. From time to time, the caching unit nay delete from itself N Infrequently used documents. Conversely, it may be pre-loaded with previously C formatted documents in anticipation of heavy use. This may be impoemented 00 under Management system control according to the business models associated with a document.

Cl The above scenario would not contain as many steps if the invention is used to display documents on an end-user's machine to their cell phone over the Internet Organisations running the publishing system in-house may also require fewer steps. Depending upon the Implementation, the order of steps may also vary. However In all cases, the unique four-stage architecture of the presentation subsystems remain the same.

It will be appreciated that the presentation subsystem, and in particular the display unit, Is not limited to on-screen display. For example, content may be sent directly to a commercial printer for one-time hard copy printing, to a sound studio for one-time listening, or to a cinema for viewing. In all cases, a 'screen' also may be understood as the display area in which a document is to be imaged, such as within a box on a Web page.

Cache, rendering, reformatting and display units may be distributed across one or more machines for load balancing and performance optimization.

Stakeholder subsystems The stakeholdersubsystems provide management functions for authors, publishers, advertisera advertising executive editors, developers, the invention's operators or any other party with an' interest in content They comprise a set of workflow applications inked to document and information repositories. These are linked via virtual private networks and an XML messaging unit to the nvention's other subsystems. In the preferred COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:57 REDBANK MANOR PTY LTD 61397441788 Page 26 00 24 Sembodiment of this invention these repositories are comprised of file system 1 hierarchies, although they well could be other stores such as relational C) databases.

LC The stakeholder workflow applications comprise of: 1. Stakeholder information captures: These associate information such as Title, Author, Summary and Business Model indicators to documents.

IO By noting these indicators, the management subsystem is able to determine the 'N Way a document should be treated, by consulting the business models to which 0 C the indicators refer.

00 2. Advertising information captures: These allow advertising ci executives-and creative staff to associate objects embedded within documents to an advertising model. An example of an advertising model could be to display a set of advertisements in random order as a page is accessed or change the advertisements if a user revisits a page, with the appropriate fees for each type of exposure.

3. Business modeling: These applications create a marketing structure around a collection of documents through associations with business models. A business model wil typically contain pricing information to which documents refer via their indicators, as well as revenue and expense splitting ratios between stakeholders. A special kind of business model is an advertising model, embodying the terms and conditions of embedded content for automated billing and display.

4. Content markup and staging: These applications are used to goven the release of documents and information from the Stakeholder's master document and model repositories to the presentation, interface and management subsystems. This allows publishers to perform functions such as setting 'opening dates' on new parts of their site, managing the document update process or rolling back their sites to previous versions of documents.

Other information captures and.functions: A numberof other functions complete the stakeholder application suite. This includes reporting tools allowing all the stakeholders to review the progress of their interest in sites and documents, COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 200R r~i~1v U~W~D flTV ~~C~ZNjf\ ril LII) Oj.j~/~iq1ItSb Page 27.

00 CI Another major component of stakeholder subsystems are the advertising and business model repositories. These hierarchies of XML docume nts a re V) referred to by indicators attached to documents. One document may be thus V) ~associated' with many business model When I.his happons, by default; the S system will determine the cheapest option for the ond-user or advertiseir or offer them a choice of under which set of terms and-conditions the document is to be made available..

Stakahoulr master document repositories are -file or document N0 management systems where documents are stored and released to 0 io presentation subsystems via virtual private networks. They also form the 0 staging area for future document release-9plus an archive of past release& Which have bown withdrawn from circuiejion.

An XML messaging unit is provkded to facilitate Information transfers between Stakeholder subsyste~ms and the other subsystems.

The preferred embodimeont of these subsystems Could be used in the following scenario: 1. A publisher nominates an application set-ice providerw oi- 6eects, to run a stakeholder application spite on their own systems; 2, The publisher registers the stakeholders to be recognized by th~e site; o I a ut oue t stakeholder application suite to stake their claim 4. A publisher submits the documnent-to the system, in so doing acknowledging t claims made by the author indintorrg 5. Business model, indicators are associated, recogriizin'g the role of advertisers, edtors, advertising executive, developer and others; 8. At any stage,.documents may bo marked up for manual optimnizatlon for image dISPlay using remote display protocols. FQr example, it might be necessary to stp image resi"zing where a pie.r's dotail must be displayed, such as with a map; COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:57 REDBANK MANOR PTY LTD 61397441788 Page 28 00 We3 t €AMela67 0 26 S7. At any stage, documents and their organisation within the eC repository may be marked up to control the timing of their release; S8,. Document tnformaton is retrieved from the various repositories via XML Messaging units by the management subsystems; 9. Application service providers rurning interface subsystems also access repositories to display Information In Web. WAP or pages described by other protocols or formats, for end-users not currently being handled by the presentation subsystems; 0 10. As requested by the user and allowed by the management 8 10 subsystem, copies of documents are released from the stakehoder's master C<N document repository to various presentation subsystems; 11, Reports are provided to stakeholder applications from the invention's other subsystems, for realtime management of documents, sites and stakeholder relationships; 1 5 12. All of the above functions are also designed to maintain their currency on an ongoing basis. For example, a document's author revenue shares may change over time as a document is updated by different people.

The stakeholder subsystem is designed to support rich collaboration between all the particiants. Therefore stakeholder subsystems may be distributed across a large number of locations, while the management subsystems are designed to be centralized over a small number of locations.

However there may also be a market for management subsystems to be deployed for private in-house use for secure publishing operations within orgarisations, such as armed forces.

Payments subsystem The Payments subsystem is the gateway by which transactions between financial institutions such as credit card companies or banks are conducted.

transactions with non-financial institutions which non-the-less manage funds, such as telecommunications carriers or utility companies, are also supported.

COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:57 REDBANK MANOR PTY LTD 61397441788 Page 29 0 0 0 *LUV27 O Cl The Payments subsystem, working under the authorization of the D Management subsystem, enables both deposits and withdrawals from accounts C) operated by all those associated with the use and operation of the system.

It is also used for the updating of account balances, risk analysis and other

o purposes.

C- The Payments subsystem also has human interfaces for manual 00 transaction entry, such as for cash or thecKs.

Interface subsystem The job of the Interface subsystem is to enable interaction between the system's secure publishing environment and other publishing systems.

This is often twotesiy because publishing document images using remote display protocols is orders of magnitude more expensive to set up and run than traditional online publishing systems. Ths Is because the entire enduser experience must be supported by the publishing system rather than simply sending off a few files for a browser to interpret and render. This means information which cannot be sold, such as a catalogue of documents for sale, will most likely be presented using cheaper Web-based protocols such as HTML and JavaScript.

Another scenario is where the publisher chooses to accept the risk of allowing readers to download encrypted content for offline use (such as large tables or diagrams), by employing an alternative publishing system. In this case the management subsystem may need to inform such document download software of details conceming.both the document and the reader.

To support business models such as these, an Interface subsystem is required to supply information stored in the management subsystem to other publishing systems. Functions of the Interface Subsystem a also included in the Presentation subsystem, allowing document browsing, searching and pricing information to be accessed from within the system. Once a user is COMS ID No: ARCS-207412 Received by IP Australia: Time 00:00 Date 2008-09-25 24 SEP 2008 23:57 REDBANK MANOR PTY LTD 61397441788 Page 00 (N interacting with the Presenttion subsystem thre is no need to leave it to make another purchase.

The operation of the Interface subsystem therefore depends on the kind of publishirig system requiring rmanagermentsysate sujpport. An-end user may wish to access a conventional web page of a publisher to browse a catalog of content available through the invention. In this case, the Interface subsystem 00 10 willprovide the pub!shr's Web serverwith such information as a full o hierarchical or list view of the content available on a site, or a search result subset of this. Pricing, conditions, sunimmary and othreriforation may also be supplied, according to stakeholder business models.

In order to apply business models to obtain the correct price for a particular end user, the Interface subsystem may also ask for or accept an enduser login. f no 6nd-user loin is suplied, afibnytnots uter prices and .conditions or no prices and conditions wilb suopplied, dependiiig oi the businbss mod6a(s) nsdciated with the' do ent Information shared between Stakeholder, Managernent and interface subsystems Is likely to be repetitous.

Information onthe end-users whereabouts may be supplied 00 o 10 to the interface subsystem from a mobile device, Intemet/Application service o( provider, telecommunications carrier or other hardware, software or other locatlon-nowing entity. End-user location details may also be approximated using information supplied by the networks through which end users are connected.

A particular embodiment of an Interface subsystem may support different levels of the functionality described. For example, in a mobile device such as a cell phone, a connection from the Management system to a carrier's own billing system may imply a logon, by virtue of possession of the phone connected to the network. In this case, the Interface subsystem provided to the carrier's WAP gateway would not necesarily need to provide a separate login function. On the other hand, for privacy or security masons, some locational functions may Q be omitted In Interface subsystems deployed in some places or disabled when the system is accessed by location sensitive' persons.

SECURITY

The division of the invention into various subsystems lends itself to the creation of security zones, safeguarding the privacy and integrity of information stored by the system. The preferred embodiment operates within (but is not limited to) six general secuity zones: 1. End users interacting using Web pages through the Interface Subsystem are considered to be in the Un-tnrted Internet zone.

End users-accessing.ilve content images using the Presentation subyste located at an Application service provider are considered to be in the endquser zone. They typically access the invention through a tr remote display protocoi or other login using a guest acc0unt through tightly controlled TCP/IP ports.

3. The publisher-zone is where interpreted document macros, screened for suspicious looking or posibly dangerous system calls, may execute.

Authorised, embedded dr linked applications, including embedded remote c- display protocol sessions, also fall within this zone.

SSignals between all subsystems are conducted using encrypted files.

This communication typically takes place over virtual private networks which themselves are encrypted.

The invention provides a system of modifying, distributing and C accounting for live document images, made suitable for transmission via remote SO display protocols through automated reformatting of source documents, with S 10 Imited selection and copying of text or graphics for publisher copyright control.

C ft enables higher value content to be sold online, plus enhances the end-user experience, making document images more readable when viewed in a live application (not downloaded like the Web's HTML) over slow networks.

Document production costs are also reduced with single-document publishing, utilizing reformatting engine(s) to handle the complexity of suitably resizing content for most devices. The system and method also secures documents for e-commerce by only allowing their images to be viewed. The viewed documents are easily read over the Internet via remote display protocols and navigated by users from their PCs, servers, w various mobile devices.

Documents are made available to the invention for reformatting, to suit a S combination of varying remoie display protocol 4nvironments, screen sizes, viewing distances, plus end-user and publisher preferences. Copyright protection is achieved by only sending live images of these documents via remote display protocols, both mpdifying the original content for easy navigation on the display device while dsabling its reproductive capabilities. Live mage transmission only occurs after the management subsystem has authorized such end-user requests. The task of billing and tracking and reformatting documents for better remote display protocol transmission is split between wo types of computing infrastructure: One serves the mrartagement subsysteM snd maintains unified contol whi.e the ther widel distributes the presentation subsystem for Image processing between machines, thus the invention can securelyenable millions of simultaneous live document image Users.

)The system attaches business model indicators to documents rather than l pricelists, the business model determines how a document is charged for under different circumstances. The billing/tracking aspect of the management subsystem uses these business models, evaluating them against end-user records and their current status, thus determining the appropriate price. In this

O

N way publishers can implement a wide range of marketing options for their C content, without having to pay for a custom-built billing and tracking system.

Finally, in relation to the Internet's rampant credit card fraud, the system Sreduces the risks for publishers in three ways, better supporting the added expense of document image publishing. Firstly, the billing/tracking aspect of the management subsystem has the capacity to distinguih 'cleared funds' from those where a dishonor from a bank or credit card company is still possible.

Publishers can therefore adjust their business models accordingly, perhaps offering bonuses for the better payments, The system is also able to identify users with good track records, informing publishers of low risk users from records generated from their prior use across all publishers- without violating the end user's privacy. And the aggregation of transactions across multiple publishers can be leveraged to get a better deal from financial institutions.

Throughout the specification the aim has been to describe embodiments of the invention without timiting the invention to any specific combination of alternate features.
