The attribute updating controller 110 may be configured for updating edition usage statistics of the edition attributes 121 and the total number of checkouts and the available number of edition instances of the edition DRM attributes 120.
The attribute updating controller 110 may also be configured for updating the edition value of the edition attributes 121 and/or the edition instance rental value and edition instance purchase value of the edition DRM attributes 120.
The DRM control subsystem 108 may further comprise a user interface 113 comprising a profile updating interface 112 therefor accessible via a client terminal 117 for updating the digital artwork edition data/profile relationships 124 within the digital artwork edition database 116 using the profile updating controller 111.
Exemplary utilisation of the network 100 will now be described with reference to one example which should not be construed as being limiting on the features and functionality of the network 100.
The digital artwork content 119 may be created by the network 100 using the digitiser 118, which may include a digital image of the original artwork 123, digital artwork content meta data (such as author, name, artwork categorisation, tonal curves and the like) and an electronic digital artwork content certificate of authenticity.
The digitised digital artwork content 119 may be uploaded to the digital artwork edition database 116 and a digital artwork edition thereof created and stored within the digital artwork edition data 122. Appropriate digital artwork edition attributes 121 thereof may be configured, such as artwork name, author name and other digital artwork content information. In embodiments, initial digital artwork edition data attributes 130 may be set. As alluded to above, an artwork edition type may be created by the network 100 and a playlist or exhibition edition types may be created by users of the network 100.
The edition owner may use the client terminal 117 to control the digital rights management thereof using the DRM attribute updating interface 114. For example, an artwork edition owner user profile type may use the client terminal 117 and user interface 114 to update the edition data attributes 130 including the edition DRM attributes 120 and edition attributes 121. Certain of these edition DRM attributes 120 and edition attributes 121 may be predetermined by the network 100 in accordance with the edition type and, in embodiments, only certain attributes may be set by an user, such as the digital artwork content collection information, edition status or edition meta data of the edition attributes 121 and/or the geographic region limitations, user access limitations or digital artwork content cycling time of the edition DRM attributes 120 and the like.
For example, the edition owner may specify that the digital artwork edition may be viewed by the specific group of end users within the North American region.
As such, the display interface subsystem 101 makes the digital artwork edition available across the network 100.
End users may use the display control interface 104 to browse for, select the digital artwork edition using the selection interface 105 and check out the digital artwork edition instance for display on the digital display device 103 using the checking out interface 106. The checkout interface 106 may be customised according to user geographic region information, user preferences and usage user statistics. Furthermore, end-users may rent and edition instance or purchase in edition instance. In this regard, the selection interface 105 may show an edition instance rental value or edition instance purchase value which may be dynamically calculated by the usage monitoring controller 109 and updated by the attribute updating controller 110.
In embodiments, the checkout controller 126 may monitor the total number of checkouts and number of available edition instances and, when reissue conditions are met (in that the total number of checkouts equals the maximum checkout limitation or the available edition instances equals zero, for example), the DRM control subsystem 108 may generate an edition reissue request which is performed by the attribute updating controller 110.
The attribute updating controller 110 may handle the edition reissue request by setting the edition status to closed and the maximum display duration limitation to a specific value (to seven days for example, to allow users with actively rented edition instance time to select a new edition), creating a new edition 122 with the same digitalised artwork content as the closed edition and the available edition instances is set to the closed edition size. Furthermore, in preferred embodiment, edition value, edition instance rental value and edition instance purchase value of the new edition may be updated according to edition usage. In alternative embodiments, edition value, edition instance rental value and edition instance purchase value of the new edition may be updated by the edition owner or by the system according to the independent authority recommendation and the like.
In embodiments, the checkout controller 126 may be configured for automatically checking the digital artwork edition instance back in when display duration thereof reaches the maximum display duration limitation DRM attribute. The checkout controller may automatically renew edition instance rental by default unless instructed to otherwise by an end user in which case the checkout controller 126 will automatically check out an edition after the edition instance was checked in due to maximum display duration was met.
In embodiment, when receiving a checkout request for a digital display device 103 of an end user, the network 100 may generate a cryptographically encrypted version of the digital artwork content 119 of the digital artwork edition particular to the requesting digital display device 103 such that only the requesting digital display device 103 or a display controller 102 associated therewith is able to decrypt the digital artwork content for display.
Each end user may pay a monthly subscription (which may be credited to the end user financial accounts) which may, for example, allow access to various functionality of the network 100 in accordance with user type including end user type which may be allowed to rent or buy an edition instance or create playlists for personal use thereof, art owner type users which may additionally be allowed to purchase, monetise and sell artwork editions and curator type users which may additionally be allowed to commercialise and sell exhibition editions.
The network 100 may automate financial transactions against financial accounts of these various types of users including charging end users for renting or purchasing an edition instance or charging owner type user for purchasing an edition, and for remunerating edition owner each time the edition instance is checked out or the edition is purchased.
The usage monitoring controller 109 may monitor the checking out and checking in of the digital artwork edition by various end-users and deriving the edition usage and user usage statistics as alluded to above.
The attribute updating controller 110 may update edition value, edition instance rent value and edition instance purchase value of the digital artwork edition data attributes 130 according to usage of the digital artwork edition.
For example, in an embodiment, the greater the usage of the digital artwork edition, the greater the value updated by the attribute updating controller 110.
In an alternative embodiment, the attribute updating controller 110 may set an initially high edition value, edition instance rent value and/or edition instance purchase value of the digital artwork edition data attributes 130 and lower these amounts until the usage of the digital artwork edition exceeds a threshold.
In preferred embodiment, this process is a part of the edition reissue process described above. In alternative embodiments, this process may be periodical or continuous. For example, every 24 hours, the attribute updating controller 110 may update the valuation attributes of the digital artwork edition data attributes 130 according to the usage of the digital artwork edition.
Using the profile updating interface 112, other users may wish to acquire rights to the digital artwork edition for the monetisation thereof across the network. These rights may be specified within the edition certificate of rights within the edition attributes 121 which may comprise rights to access and use the edition, rights to commercialise the edition across the network 100 including the right to sell edition, rights to rent or sell an edition instance and right to sublicense the above rights to other user profiles.
The profile updating interface 112 may display the digital artwork edition value thereof dynamically calculated by the attribute updating controller 110.
As such, other users are able to acquire sublicense rights to the digital artwork edition and purchase the digital artwork edition by initiating an electronic payment (or allocation of user profile credit) determined in accordance with the digital artwork edition value attribute.
In embodiments, the DRM control subsystem 108 may comprise an auction controller configured for displaying the determined digital artwork edition value and receiving bids in relation to the digital artwork edition wherein, upon expiry of an auction period, the auction controller is configured for selecting a user profile associated with a highest bid amount to acquire sublicense rights to the digital edition and purchase the digital artwork edition by completing a user profile credit allocation payment or electronic funds transfer payment for the bid amount.
When a sublicense or sale rights is acquired by another user, the profile updating controller 111 updates the digital artwork edition data/profile relationships 124 within the digital artwork edition database 116 and generates the edition reissue request to be handled by the attribute updating controller as alluded above.
A new sublicensee/edition owner associated with the reissued digital artwork edition is therefore able to configure the same or a separate set of digital artwork edition attributes 121 or edition DRM attributes 120 in relation to the reissued digital artwork edition to distribute and monetise the digital artwork edition across the network 100.
For example, a new sublicensee user may be able to use the edition and DRM attribute updating interface 114 to define DRM limitations for the reissued digital artwork edition for display in Australia by up to 50 users simultaneously. As such, in the aforedescribed manner, the network 100 may monitor the usage of the reissued artwork edition and allocate credit and/or initiate electronic financial transactions in favour of the new sublicensee user according to the usage patterns within Australia.
