FR2811839A1 - Registration of intellectual property rights attached to a digital work, uses digital signatures and external watermark generation to provide data that is held by a trusted third party to uniquely identify the work - Google Patents

Abstract

The procedure computes a digital signature from the work, and transmits (2) information on the work and its exploitation to an external database which returns (3) identification data and a second digital signature, which is embedded in the work as a watermark. The watermarked version is then sent (5) to a trusted third party, along with both digital signatures and the identification data.

  "Method and system for registering intellectual property rights attached to a digital work" The present invention relates to a method for registering intellectual property rights attached to a digital work. It also targets a

system for its implementation.

  By digital work, we mean any work or creation whatever its nature such as image, text, sound, video and its origin when it is provided in a digital format whatever the medium, for example on a network digital communication such as the Internet,

  on a magnetic, optical or semiconductor support.

  By intellectual property rights, we mean: 1) the copyrights attached to original works and creations, whatever their nature, be they aesthetic, literary, graphic, sound, olfactory or others, 2) rights related to copyright attached to

  the interpretation of works and creations.

  The management of intellectual property rights attached to digital works or supplied on an electronic medium currently represents a major challenge in the world of the Internet. The worldwide circulation of works of all kinds on the Internet results in real difficulties on the one hand to inform Internet users of the existence of intellectual property rights and on the other hand to enforce these rights. Furthermore, the recurrent problem arises

  problem of authentication of digital works.

  Online SEO sites are already available on the web to provide authors and creators of digital works with evidence of certain dating of their works. We can notably cite the

- 2 - 2811839

  SEO sites www.legalis.net or www.protecrea.org which offer for intellectual creations on electronic media the deposit of electronic versions of traditional Soleau envelopes. Furthermore, there are already rights management methods such as that disclosed in document US5629980 in which the distribution and use of digital works are controlled. In this document, the owner of a digital work associates to his work usage rights which define how the work can be used and subsequently distributed by the purchaser. Digital works are stored in a repository which processes each request for access to a

  works by examining the associated usage rights.

  There are also known rights management methods using electronic watermarks or access keys. The document describes steganographic techniques allowing control information to be transported invisibly and indelibly by the information signal. These techniques provide protection in terms of digital rights of an information signal regardless of

  analog-to-digital conversions experienced by this signal.

  However, none of the current methods makes it possible to resolve the question of the durability of the proofs of creation over long periods of time. Indeed, no online filing or referencing site can guarantee a creator user of this site the availability of access to digital works, due in particular to the rapid obsolescence of software and hardware IT tools with regard to duration Copyright Law which provides for a period of

years after the death of the author.

- 3 - 2811839

  The purpose of the present invention is to remedy these drawbacks by proposing a method of recording intellectual property rights which ensures its users durability of proofs of creation date beyond the risk of obsolescence.

IT equipment.

  This objective is achieved with a process for registering intellectual property rights attached to a work supplied on an electronic medium, comprising: - a calculation of a first electronic signature of said work, - a transmission of information relating to said work and to its use at a first external entity, receipt of said first external entity, identification data of said work and a second electronic signature of said work, - a watermark of said work comprising an incorporation of said second electronic signature in said work, to provide a tattooed version of said work intended for distribution, and - storage in a database of a second external entity, of a set of rights registration comprising said work, its tattooed version, the information relating to said work, said first and second electronic signatures, and the d identification data. Thus, with the method according to the invention, the storage of both digital works in their original and tattooed version and electronic signature and identification tools with an authorized trusted third party will make it possible, when necessary, to reconstruct the whole process

- 4 - 2811839

  security and authentication regardless of

  the current state of IT tools.

  In a particular embodiment, the set of rights registration comprising the work, its tattooed version, the associated information, the identification data and the electronic signatures is transferred directly from a local requesting site to the storage means. of the second external entity via at least one communication network. A realization option saves the information allowing to strongly authenticate the creator (signature

depositor's electronic).

  In another embodiment, this set of rights registration is temporarily stored on a server site using said method and connected to a requesting local site via at least one communication network, then transferred to the storage means of the second entity outside via the communication network. Preferably, the information relating to the work which is transmitted to the first external entity includes the first electronic signature of the work

  and possibly the electronic signature of the depositor.

  This step of transmitting information relating to the work to the first external entity is preferably time-stamped. It is the same for the stage of storage in the second external entity of the set of registration of rights attached to the work is time-stamped. In a practical form of implementing the method according to the invention, the first external entity is an organization responsible for issuing an identification number for each work submitted, while the second entity

  outside is an authorized trusted third party.

- 5 - 2811839

  In addition, the method according to the invention can advantageously comprise a sequence of restitution of a set of rights registration attached to a

digital artwork.

  According to another aspect of the invention, a system is proposed for registering intellectual property rights attached to a work supplied on an electronic medium, for implementing the method.

according to the invention.

  This system includes: - means for calculating a first electronic signature of said work, - means for collecting and transmitting information relating to said work and its exploitation to a first external entity, - means for receiving, coming from said first external entity, identification data of said work and a second electronic signature of said work, - means for tattooing said work by incorporating said second electronic signature into said work, so as to provide a tattooed version of said work intended to be broadcast, and - means for storing in a database of a second external entity, a set of rights recording comprising said work, its tattooed version, information relating to said work, said first and second signatures electronic, and

identification data.

  The recording system according to the invention can advantageously include means for recording an electronic signature of the depositor, if the latter has means allowing this signature, as well as a

timestamp of the deposit of the work.

- 6 - 2811839

  The tattooing means can advantageously be arranged to register in an applet information relating to intellectual property rights and the conditions of use attached to the tattooed digital work. It is also possible to provide that the recording system according to the invention further comprises means for temporarily storing sets of recording rights containing digital works, their tattooed versions, and electronic signatures, identification data and information. partners, before their transfer to

  storage means of the authorized trusted third party.

  Other advantages and characteristics of

  the invention will appear on examination of the description

  detailed description of a mode of implementation which is in no way limitative, and of the appended drawings in which: FIG. 1 schematically illustrates the method of registering intellectual property rights according to the invention; and - Figure 2 is a block diagram of a system

according to the invention.

  We will now describe, with reference to the aforementioned figures, an embodiment of a rights registration system according to the invention, at the same time

  time that the process implemented in this system.

  A server implementing the method of registering intellectual property rights according to the invention, hosts a site accessible on the web. This is to first describe the main graphical interfaces offered to the user of this site. a home page presents on the one hand, the service of establishment of an electronic proof of paternity and tattooing of the media intended to be distributed, and on the other hand,

- 7 - 2811839

  services for the use of tattooed media, such as the display of rights, payment per view ("pay per view"), or monitoring ("tracking") of the tattooed media broadcast. The home page leads in particular to a page to enter a set of information relating to the author and the work, in particular its title, the type of work: initial work, composite, derivative, collaboration, collective, the possible existence of rights included in the case of composite or derivative works, authorized rights, and contacts. In the case where the user has means of electronic signature (means of authentication of the person), he uses these means

  to electronically sign his deposit.

  After this entry page, a file opening page containing the digital work to be protected is successively displayed, and a page for ordering the steps for establishing electronic proof of

  creation and tattooing of the work's support file.

  The management server according to the invention also produces a page providing the user of the site with the results of the operations carried out on his behalf, in this case a work identification number.

  digital (IDDN) and the tattooed digital work.

  In a first variant embodiment, the management server temporarily stores during a protection operation, the digital work to be protected, information relating to the work and to its author (s), the IDDN number, the electronic signatures and the tattooed digital work, before transferring this set of rights registration to a trusted third party authorized by secure means of transmission.

- 8 - 2811839

  In a second variant embodiment, the management server does not receive, even temporarily, the digital work to be tattooed and the tattooed work which are transferred directly with the other protection and authentication elements (IDDN number, electronic signatures, information) to the trusted third party authorized by secure means of transmission. A management server according to the invention comprises for example the following software modules: a module for sending web pages to a requesting local site, a module for processing information and data entered from the requesting local site, - a module for calculating a first electronic signature SE1, - a module for communication with the database server of the first external entity providing the IDDN number, including (i) the transmission to this server of information relating to each work and the first electronic signature and (ii) the receipt of the IDDN number assigned to this work and a second electronic signature SE2, - a watermarking module of the work by incorporation in the file or media support of this work of the second electronic signature provided by the first external entity, and - a transfer module for each set of rights registration [initial work, tattooed work, associated electronic signatures, information and identification number] El, ..., Ei, ... Towards a database of a second external entity representing a

trusted third party empowered.

- 9 - 2811839

  This management server can also include, by way of nonlimiting example, the following service software modules: - a module for supplying the local site requesting an applet for displaying rights and conditions of use, - a module management of paid consultation modes, - a tracking and tracking module

recorded digital works.

  We will now describe an example of use of a rights registration system according to the invention, firstly, during an initial registration process, then secondly, during a recovery process of the elements of registration for example in the context of a legal action requiring the presentation of proof of creation of a

work on a digital medium.

  A creator of an original digital work, for example a digital painting work, plans to distribute this digital work on the Internet from a website, with specific conditions of exploitation and reproduction. This digital work can be stored on the hard drive of the creator's computer or his authorized representative or on any other electronic medium.

  of digital data ME1, with reference to FIG. 1.

  Prior to putting his digital work online, the creator or his user representative accesses the site using the rights registration process according to the invention, from a computer connected to the Internet. The management server of this site transmits to the user a home page offering the service of recording a work. It should be noted that this recording service can be either free access,

- 10 - 2811839

  either access subject to prior registration of

  the user with or without subscription.

  At the request of the management server, the user provides a set of declarative data on the work concerned, then opens the file containing this work which is transmitted, in secure form or not, to the server

Management.

  The management server calculates (1) a first electronic signature SEl of the digital work, then enters into connection (2) with the server of the IDDN database and executes the procedure for requesting an IDDN identification number by supplying to this database server the required information and the first

  electronic signature of the digital work.

  In return, the database server transmits (3) to the management server an IDDN identification number and a second electronic signature SE2 of the digital work. The management server then performs a watermarking (4) of the digital work according to now conventional techniques by incorporating the second signature

  electronics provided by the database server.

  Then the set of rights registration comprising the initial work, the tattooed work, the two electronic signatures, the declarative information and the IDDN identification number, is transferred (5) by the management server, in secure form. or not, to an authorized trusted third party storage unit

  via one or more communication networks.

  After all of these operations have been carried out, the management server sends a registration acknowledgment to the user and the information and data necessary for a subsequent return of the rights registration set. In addition, it can provide the user with an applet for displaying the rights and conditions of use, intended to be included.

  in the electronic broadcast medium.

  The user then undertakes the dissemination of the tattooed digital work on the Internet or on any other electronic ME2 information medium. Any third party receiving this work on their computer is made aware of the rights attached to this work

  and conditions of its use.

  If, several years after the registration of the rights attached to this work, legal proceedings lead the author or his beneficiaries to have to prove that he has a certain date of creation, the authorized trusted third party will then give the 'together

  of registration of rights attached to the work concerned.

  With this set, any qualified person, for example an expert in intellectual property or in computer law, will be completely able to be able to trace the history of the recording of the work and

  to establish the authorship of the work.

  Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention. In particular, all of the registration data is not necessarily transmitted in a single block to the authorized trusted third party, but can be transmitted in several stages spaced in time depending in particular on the processing time of the request d 'identification by the first external entity. Furthermore, it is conceivable that other elements of identification, authentication or security could complete the set of rights registration already stored at the third party of

empowered confidence.
