SYSTEM AND METHOD FOR MONITORING A DIGITAL WORK

Abstract

The invention relates to a method and system for monitoring an original work, such as a digital work, and provides a reporting and auditing service for example for monitoring and deriving a royalty payment in favour of a rights owner.

A unique identifier for a digital work is established. The work is typically stored on, and retrievable from, a database. The work is typically transmitted in a digital format from a subscriber who asserts ownership of the work and that the work is an original work. A categorisation of the work is then performed to provide at least one form of category data in accordance with at least one criterion The category data is included in an indicia associated with the work and an indicia includes a time and date stamp of receipt of the work from the subscriber.

The system operates to compare the work with content of third party databases in order to determine whether the work matches any content of a third party database and provides a clearance certificate when no matches are indicated. The system also generates a root identifier which associates both the indicia and the clearance certificate with the work so that future use of the work, by a third party is monitored in order to report usage to the subscriber and/or rights owner.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0060] Referring to the Figures generally, and in particular FIGS. 3 and 12, there is shown a global synchronisation platform (GSP) which stores files and associated ownership metadata and file qualitative and quantitative metadata, allows buyers to create a production (FIG. 3 step 1) search for files on the system (FIG. 3 step 2), license files according to specific licensing parameters (FIG. 3 step 4), generate cue sheet (FIG. 3 step 6, 6a, 6b) recording actual content usage and associated metadata for onward reporting (FIG. 12 step 91-98), and notify licensors (FIG. 3 step 7) so that they may verify the accuracy of cue sheet/usage reporting (FIG. 3 step 8 & 9).

[0061] Buyers and suppliers may be differentiated at login and in use are directed to different interfaces and tool sets. It therefore follows that a buyer will need to use different login details if they would like to set up a library on the system and become a supplier, and vice versa. A buyer can license music or content for use in their creations. A supplier who may be a subscriber can create their own unique library, upload their music or files, and set the licensing terms of the said files. In an alternative embodiment buyers may also be sellers.

[0062] FIGS. 4 and 13 depict key stages in a method that provides a unique identifier for a digital work. The work is stored on, and retrievable from, the host system along with ownership metadata (including multiple ownership and publishing rights and third party tagging information), and file qualitative and quantitative metadata. The method includes the steps of: receiving a file of a work in a machine readable format, such as a digital WAV (Trade Mark) file format, from a subscriber who asserts that the work is an original work. The system then categorises the file to provide category data in accordance with at least one criterion, including or embedding this category data in the form of an indicia in the digital file.

[0063] The indicia includes: a time and date stamp of receipt of the work from the subscriber. The system then compares the work with content of third party databases in order to determine whether the work matches any content of any third party database. If the work does not match anything that is stored on a third party database a clearance certificate indicates that no matches are found. The system then provides a root identifier which associates both the indicia and the clearance certificate with the digital work so that future use of the work by a third party is monitored in order to report usage to the subscriber and/or rights owner.

[0064] FIGS. 4 and 13 depict files being imported into the metadata framework culminating with a unique registration and identifier that not only identifies the work and alternative ID Tags for the work but also multiple rights on a territory by territory basis associated with the work and its derivatives. When a file is imported it is verified, such that the supplier of the work is able to offer it confidently without risk of it being a copy of an earlier work. If, when a work is imported a risk of any rights infringement is identified, a block or warning is issued and the system refused to upload or recognise the work. Likewise a licensee is able to acquire a work with confidence that it does not infringe another party's copyright.

[0065] FIG. 4 shows an overview of a system that imports files into the database. The supplier registers an account and logs onto the system (step 1) in order to upload the file and associated ownership metadata to the database (step 2). When the file is imported, the system checks if an identical file exists in the database (step 3), if the file being uploaded is a duplicate the process is aborted and no import is made to the database. If the file is not a duplicate, the system checks if a duplicate of the file metadata exists in the database (step 4), if duplicate metadata does exist the process is aborted and no import is made. If no duplicate metadata exists the system checks if similar content exists and creates a unique identifier and finger print for the digital file.

[0066] Checking of unique identity of works and ID Tags, as well as date, time and optionally location of generation of the work; as well as acquisition time and date, may be integrated as part of the host system or can be separate therefrom (step 5). If the process in step 5 is aborted no import is made.

[0067] If the system acquires the necessary fingerprint (step 6), the finger print and file are stored in the metadata framework along with other all other related metadata including additional associated ID tags, such as Google ID (Trade Mark) and alternative signatures on the server.

[0068] An outsourced digital fingerprinting or digital signature service or affiliate system is used to verify authenticity. Examples of such digital signature services for music tracks include Echonest (Trade Mark), Gracenotes (Trade Mark) and Shazam (Trade Mark). All third party authenticity tools are recorded in the metadata framework. This also allows for multiple or alternative publishing rights for the same piece of content. The invention enables right holders to hold all ownership data in one location and utilises alternative broadcaster platforms and affiliated monitoring tools to manage output.

[0069] If a digital file is verified as unique (that it is not a copy or duplicate of another work) the system firstly introduces a time-stamp associated with the work as an identifier. This effectively registers and legitimises the work and its claimed rights ownership. Therefore this step creates a detailed record of rights ownership, writer and publisher as well as a record of any royalty sharing arrangement.

[0070] An authenticity check therefore compares a newly presented work, using open source software, which enables a comparison to be made currently with databases of more than 60 million existing tracks. This is considered an important part of the invention as it mitigates risk of copyright infringement by virtue of the fact that a work is rejected (or labelled as questionable) if a significant portion is matched with an existing work.

[0071] The system allows the uploading of multiple files and the editing of their metadata. It incorporates an automatic step of deriving metadata from musical tracks and the ability to add and/or edit metadata for each track. This process obtains quantitative musical attributes, including such metadata as beats per minute, opening and closing key, major/minor, root tonic and instrumentation. Basic qualitative attributes are recorded, for example as bright, such that expressions or mood can be derived by using keywords or synonyms. A look-up table of words and synonyms provides a glossary of industry keywords for indexing and retrieving analogous themes.

[0072] During the upload process a digital work (such as a piece of digitized music) is examined to check for copyright infringement. Further mitigation is provided by a user flagging capability. This is where users are asked to rate the accuracy of the music metadata, and the quality of the music, and whether users wish to create and share playlists of related music.

[0073] FIG. 13 is a flow diagram illustrating an example of the operation of a host system to upload files. Library (uploader) creates a new account 60A or logs into an existing account 61 in order to upload a file 62 to the host system. A module 63 checks if the file signature exists within the host system. A duplicate signature is treated as a duplicate file and the import process is aborted 65.

[0074] If a signature file does not exist within the host system a module 64 checks if the file's signature exists within an affiliate system. If the signature of a file exists within an affiliate system, another module 66 checks if the ownership metadata of the file that is being uploaded, matches the metadata of the file with the matching signature on the affiliate system. If the ownership metadata does not match the upload process is aborted 66A.

[0075] If a file signature does not exist within an affiliate system, qualitative and quantitative metadata is generated for the file 67 being uploaded and the file and metadata is saved at the host 68. Host system metadata 69 is collated with metadata generated by the host system 68 or an affiliate system 70. A unique URL for a music file and its metadata that can be shared is therefore generated. If a library (uploader) intends to upload more files 71 the process is repeated from step 62. If no more files are to be imported the import is completed 72.

[0076] FIG. 5 shows digital cue sheets are stored on a centralised global repository openly available to all related parties; rights owners, production companies, broadcasters and collecting societies. Use of the system therefore guarantees accurate reporting of music identified by a collecting society for use in media productions. It also provides a tool for production companies to precisely log music and manage/complete digital cue sheets. Data can be automatically exported/retrieved by collecting societies and/or broadcasters.

[0077] The creation of digital cue sheets (used for collecting performances royalties) enables all parties in a value chain (licensors, licensees, broadcasters and collection societies) to view, verify, correct, and distribute digital cue sheets quickly and efficiently.

[0078] The digital cue sheet provides a direct link (URL) to the music file along with all other related metadata. This facility provides a re-licensing facility for both similar reversions of the production (say a cut down version) or the licensing in a completely different non-related production. The unique cue sheet may be served along with the production at broadcast, and thus enables the re-licensing of music used in that production to both business licensors and consumer licensors.

[0079] FIGS. 1 and 2 shows overviews of systems that oversee music licensing. The systems enable a buyer to create a production, which allows the buyer to group multiple tracks to be licensed. The buyer adds their desired tracks to the production and licenses them. This creates a cue sheet for that production. The production cue sheet can be reverted into similar production (of varying lengths) and associated cue sheets, providing the licensor with various discounts.

[0080] Geo-blocking is an optional technique that is operable by an internet service provider (ISP), carrier or government in the event that certain materials are not to be accessed from, or made available, in a specific territory or jurisdiction.

[0081] FIG. 3 shows a more detailed overview of a system that oversees music licensing. The system enables a buyer to create a production which allows the buyer to group multiple tracks to be licensed (step 1).

[0082] The buyer then searches for tracks to license (step 2). This step utilises a search algorithm. The buyer adds the desired tracks to the production (step 3) and licenses them (step 4). The license metadata and associated usage rights are added to production (step 5) and automatically imported into the digital cue sheet track selection process (Step 6).

[0083] The population of the digital cue sheet is verified by checking a unique digital work identification number which is referred to as a SV-ID which is an acronym for a proprietary ID number. Use of this identification number process prevents two tracks with similar names from being confused and so ensures that the correct recipient (author, composer, performer, record company) receives a payment. This also enables auto creation and verification of the digital cue sheet.

[0084] The digital cue sheet is populated with usage data and includes such information as track name, ID and license type (for example advertising, trailer film), license use (for example TV, radio, online) and music use type (for example background, foreground signature music, or credits), duration and location. This information is essential for back-end royalty payments.

[0085] Referring to FIG. 3 the system notifies the unique rights owner (step 7). The unique rights owner acknowledges cue sheet entry and is verifies that data relating to the work is correct and complete (step 8), the acknowledgement is stored in the cue sheet database. Currently rights holders have no involvement in this process and do not always know when their music has been licensed. The electronic record will calculate licensing fee and produce a self-billing invoice on behalf of the rights owner. Optional metrics includes process to analyse of how much of music is used and estimate potential performance royalty payments. Music usage may be searched, reviewed and selected using the invention as key statistics and other data are available for each track.

[0086] All of these affect the amount of royalty payment to be made. If the rights owner establishes that something in the digital cue sheet is incorrect (e.g. duration or usage), the rights owner/library/publisher may request that the production company/broadcaster makes a correction. The system monitors the process and, after a pre-agreed period (such as 60 days), a third party or overseer is introduced to provide intervention and/or mediation.

[0087] If a production company licenses the music and uses it in contravention to the license purchased. The musical rights holders have the ability to report any such violations.

[0088] The system may comprise an edit decision list (EDL) importer, which helps pre-populate usage and can include data relating to track name and duration of music used, which is cross referenced against specific identification data for example ownership details and author (steps 6A and 6B).

[0089] FIG. 14 is a flow diagram illustrating an example of a buyer operating the host system to license files for a new production or reversion an existing completed production and reuse the licensed files for a similar production, (for example a shorter version of the same production). A buyer logs into 112 or creates an account for 111 the system and chooses to create a new create a new production 115 or reversion a production from the cue sheet registry 113. If the user chooses to revert to a previous production, metadata from the previous production is generated and added to new production 114. The buyer then adds new files 116 and licenses the production.

[0090] FIG. 12 is a flow diagram illustrating an example of the operation of the host system to create a cue sheet. If the file to be licensed exists 91, the metadata for the file is procured from the database 92. If file is new the system checks if the file ID exists in a third party affiliate system 93. If the file does exist metadata is procured from the affiliate system 95. If the file ID does not exist in an affiliate system, new metadata is generated for the file 94. After metadata has been procured or generated for the file, metadata is provided to the cue sheet 96. User metadata is then added to the cue sheet to complete the entry of file metadata 97. If more files 98 are to be entered, the process starts again from step 91. If no more files are to be registered on the cue sheet, and the library and associated right's owner are notified 99 and the process is completed.

[0091] FIG. 7 shows search facilities incorporated in the host system. A user on the host system can run a search on metadata stored on the database (step 1). An algorithm is used to search for file metadata and the result is displayed for user to either buy (step 2a) or preview (step 2b) files on the host system. When either step 2a or 2b are completed the statistics aggregate (steps 3a and 3b) and are used to improve the algorithm (step 4).

[0092] Algorithms provide precision results that augment basic meta-data with statistics on popularity, trends in usage and the ability to detect possible musical substitutions. That is, the ability to detect a similar track to one which is popular without infringing copyright.

[0093] Ideally affinity data is also provided and obtainable for production music tracks and commercial ones. Thus producers are able to select tracks similar to existing styles and so are able to save considerably compared to the cost better known commercial track.

[0094] This aspect of the invention is also capable of recommending similarity metrics on either external tracks or tracks and provides a further refinement which enables a keyword based search mechanism to aid music signature based discovery.

[0095] The digital cue sheets assist with automatically searching non-music data and how the system improves searching and selection of tracks according to user defined search criteria and/or an enquiry. In addition digital cue sheets are accessible via a laptop, pad, hand-held device or mobile telephone (cellphone).

[0096] In all the aforementioned mobile communication devices a playlist is able to be provided to users in a format which is simple to use and browse and which is available to a wide range of users, including: composers, film editors, general public and musicians. This playlist helps users to create and share playlists of music or to explore use in specific scenarios. The playlist assists in creation, aids categorisation and enhances music discovery and recommendation engine.

[0097] The system is ideally available on iOS (Trade Mark) and Android (Trade Mark) platforms. It offers a cut down version of the service with music licensing limited to streaming (for example 56 kbps MP3) services. The system is seen as a search and discovery mechanism, enabling libraries to promote their work and users to sample create and share playlists.

[0098] FIGS. 6 and 8 depict payment triggers. At the moment when a digital cue sheet is completed by a licensee, such as a production company, a synchronisation fee is amortised in favour of the rights holder (such as a composer). The composer library or rights owner may then review reported usage and accept the synchronisation fee by acknowledging content of the digital cue sheet. It is appreciated that references to a licensee and licensor are synonymous to seller and buyer respectively.

[0099] On acceptance the digital cue sheet makes an auto payment through its self-billing process. Thus the digital cue sheet completion and acknowledgement acts as the payment trigger. This can then be used to analyse how much of the music is used and potential future performance royalties based on public performance. The ability to analyse future income enables a secure assurance, for example for secured loans.

[0100] The system may be used to reference different data sources and produces an open digital cue sheet archive of acknowledged, verified and unverified digital cue sheets as a global synchronisation platform (GSP). This enables a broadcaster to collect a digital cue sheet and include it in a transmission log.

[0101] This enables digital cue sheet data to be automatically exported from the global synchronization platform (GSP) to a broadcaster's transmission log. The key benefit is that structured data is auto imported instead of relying on a manual import per digital cue sheet, which leads to inaccuracies. This means that if broadcasters use the global synchronization platform (GSP) to source music then they can work directly with the invention which performs royalty computation, tracks payments and fulfils collection.

[0102] Digital cue sheets can be integrated with a crawler of transmissions of productions on television, radio and the Internet.

[0103] Musical rights owners are then able to be notified in real-time of the usage of their music and so that each party receives an accurate record of what is due to them. Similarly, broadcasters are able to track the fees required to pay for performance royalties.

[0104] The notification system also enables musical rights holders to check actual usage of their music in production terms, such as; license type (for example advertising, film), license use (for example TV, radio and online) and music use type (for example background, foreground signature music, or credits) and its actual duration within a production. Users are able to update digital cue sheets and checked and alter them as appropriate. Again producers and broadcasters are party to any such changes as they may affect both synchronisation and performance royalties.

[0105] Monitoring services may be built into the invention so that it can conduct web crawling in order to seek unauthorised usage. User and usage patterns may also be monitored and suspicious behaviour flagged.

[0106] FIG. 9 depicts performance usage tracking. The host system provides metadata of licensed files on its system to detection agencies (step 1) such as the music-usage detection systems BMAT (Trade Mark), SoundExchange (Trade Mark) and TuneSat (Trade Mark). These agencies search for the use of the licensed files, such as through the use of online crawlers (step 2). The results of the searches are sent to the host system (step 3). The host system will then identify registered and non-registered usage (step 4) using the cue sheet database.

[0107] Key seller or buyer account holders on the platform have the ability to add, remove and manage other users in their organization and to set permissions directly rather than have to rely purely on centralised administrators. An extension to the music rights management includes multiple rights owners and percentages of royalty that are paid to each interested party.

[0108] The invention includes a granulised metadata framework and a unique search functionally. The accuracy of a digital cue sheet ensures this income is maximized with digital tracking to ensure all payments are made to rights-owners.

[0109] The invention will include a streamed music licensing purchase system enabling the licensing of low resolution music files to be linked and streamed alongside online broadcast platforms (such as YouTube (Trade Mark) and Vimeo (Trade Mark)) and mobile APPS and games. Licensed music files are of stream quality (for example 56 kbps MP3) as opposed to full production quality (320 kbps MP3) as used in television broadcasts. With this particular type of licensing, the music is streamed from the servers and mixed with the visual content rather than being downloaded.

[0110] Accurate use of the content is monitored at all times. Further licensing opportunities are available in that music used in one broadcast or programme can be re-licensed directly to another programme without having to visit the website as this licensing can be completed directly via the global synchronization platform (GSP) cue sheet system.

[0111] It is understood that the system may be configured in order to be accessible and usable form a mobile communication device, laptop computer, mobile telephone (cellphone), potable tablet or palm held device. In addition to time and date stamping, location specific data may be included in the metadata so that geo-labelling is included in the

[0112] So far as third-party providers are concerned, authenticity of data is assured by way of assured third party contacts and licensing terms ensure that from Moodagent (Trade Marks) and TuneSat (Trade Marks).

[0113] Data protection is achieved by encrypting personal data so that it is accessed only by appropriate parties. The invention optionally includes a training system to prevent attempts to extract information from unauthorised employees, for example over the phone or via email.

[0114] Errors with electronic transactions may also be tracked and monitored so that these can be reported to an industry merchant service provider or compliance department or official.

[0115] The present invention therefore enables unique service and licensing tools to be used automatically by parties to an agreement.

[0116] Refinement of musical analytical software is able to automate the importation of music metadata process.

[0117] It is also understood that the method may include the step of providing a unique digital ID and Internet URL, so as to make all digital cue sheets are retrievable by all licensing parties; production companies, broadcasters, collecting societies, right's owners.

[0118] Optionally the method includes the step of providing pro forma royalty calculations based on digital cue sheet licensing data, and live tracking of broadcast channels (digital, terrestrial, online).

[0119] Musical works rights management include checking and updating ownership data and royalty sharing arrangements.

[0120] Music quality analysis is performed by using search terms in combination with a database of tracks and with discovery and recommendation engine features which search authenticated tracks on the database.

[0121] Digital signature recognition enables automatic checking of data, for example in order to identify unlicensed sampling data. In addition digital signature checking assist in creating a unique signature to be registered with ownership details on the system database.

[0122] Additionally repository usage and verification of different parties who interact with the system are recorded and storedso creating an audit trail, as shown in FIGS. 5 and 6.

[0123] It will be appreciated that the invention has been described by way of examples only and variation to the aforementioned examples may be made, without departing from the scope of the invention, as defined by the appended claims.
