. What is the confidentiality level ?

Secrecy and confidentiality are at the heart of our system. Indeed, your document will at no time leave our computer workstation; we will thus be unaware of its contents. Our procedure consists in achieving a digital fingerprint with the algorithm called SHA-256. This fingerprint provides no information that would enable the file to be restored. It is this fingerprint that we are electronically signing and timestamping.

. How does the proof arrive on my desktop computer ?

The proof arrives on your computer desk thanks to our automated process. Your proof is created directly as a zipped envelope in ".asice" format. It can be submitted as evidence in court.

. What does the electronic signature offer ?

La signature électronique permet de certifier un document. Pour signer le document, MaPreuve utilise un certificat numérique qualifié RGS **.

. What does the RGS qualification signify ?

The RGS stands for "General Security Reference". This is the new French qualification to protect electronic exchanges between the State and individuals, its application decree was released in May 2010.

. And your timestamping service ?

We set up a time server connected to 4 atomic clocks, which allows us to provide an extremely precise certified date and time.

. What receipts of proof do you offer ?

You will receive your proof and a receipt of proof.
Your proof is constituted on your computer workstation by a zipped file (.zip or .asice) containing your original file accompanied by its digitally signed and time-stamped fingerprint and a proof certificate.
The receipt of proof is an attestation which contains the executed process. You will receive it by certified email thanks to an RGS electronic certificate. In addition, you can verify that we are the the sender of this email thanks to the integration of our Certigna authority into the Windows, Mac and Mozilla operating systems.

. How can I verify the signature and timestamping of the generated fingerprint ?

Nous avons développé un outil de vérification en ligne qui peut être utilisé à tout moment. Ce service gratuit permet de vérifier l’horodatage et la signature électronique en s’assurant que l’empreinte associée correspond bien au fichier inclus dans l’enveloppe zippée.
As we use industry standards in terms of security, this verification can also be performed using tools compatible with these standards.

. Can I highlight my protection on a website ?

We have developed a "MaPreuve" seal which is available free of charge in your customer account. You can download it and place it for example below your photo. When clicked, the user will access the details of your proof. In addition, the mention that you are protected dissuades most of copiers.

. The music ?

Our technology is also about music. With MaPreuve, you can save your work in its entirety but also your texts, arrangements, chords or partitions.

. And for video games ?

The legal protection of the video game involves asking what a video game is in the legal sense.
Question frequently asked before the judges, who in the judgement of the First Civil Chamber of the Supreme Court dated June 25, 2009 (No. 07-20387) qualified the video game, "a complex work". A complex work means that the video game can not be protected as a whole but each of its elements can be protected in accordance with the specific legal regimes to which they belong: music, software, databases, designs, characters,...

It is therefore important to legally protect all elements of a video game, separately and not to protect the game as a whole. These elements, which are governed by copyright or related rights, may be registered on MaPreuve.

. Can I protect an object or a three-dimensional creation ?

We advise you to take a photo or even better a video commentary that can be protected with MaPreuve.

. The trademarks and logos ?

The protection of a French brand by the INPI costs more than 200 euros for 3 classes. It is limited to 10 years, but is renewable. The deposit with the INPI confers a right of ownership on the mark.
If a trademark incorporates an original logo, copyrights may be conferred on that logo, so it is important to provide proof of the date of creation of that particular logo prior to the filing of the trademark.

. Inventions are also concerned?

Our site allows to give a certain date on an invention. For example, if you deposit an invention on MaPreuve, and another person files a patent later on the same invention, you can assert your rights, under certain conditions.
In addition if you are unsure of filing a patent, you have an interest in protecting the various R&D stages and your invention on MaPreuve.
The patent filing gives you a property right.

. Concerning drawing and models ?

The creators of designs can choose between two ways to protect their works :

  • Soit via le droit d'auteur,
  • Either via industrial property, a deposit at INPI confers a limited property right to 25 years.

. And for know-how ?

Know-how is a set of organizational or technical knowledge, business that is secret, substantial and identified.

Expertise must be precisely identified in order to determine its characteristics.

To keep the secret, must be put in place in the company safe spaces, limit it to a number of employees, etc..

The know-how is not the object of right of property, nevertheless its usurpation by a third party can be sanctioned, civil or penal.

Theft expertise by an employee shall be punished by imprisonment.

To provide proof of its expertise, it is strongly advised that a company has to describe it precisely on www.mapreuve.com ....

. As part of a cooking recipe ?

Recipes are not legally protectable; the best protection for a recipe is to maintain its secrecy and to carry out a confidentiality agreement with the employees.

On the other hand, if you want to show that you are the recipe creator, we recommend certifying and dating it on MaPreuve.

Grâce à l’essor de la pratique de la cuisine à échelle mondiale et à la réputation de la gastronomie française, la cuisine est devenue un art au fil des siècles. Tel un écrivain ou un artiste peintre, il est également possible de protéger ses créations culinaires.

Also, if you have a logo associated with a recipe trademark, you can immediately protect it on MaPreuve.

. How Intellectual Property Works

Intellectual property is a legal term that refers to creations of the mind. It can be divided in two main categories: :

  • The "literary and artistic property" that protects creations of all kinds. If the work is original it is the subject of copyright. But in case of exploitation or dispute, you must provide legal proof of your creation, this is what offers the site MaPreuve.
  • Industrial Property found there mainly patents and trademarks. In France, these activities are managed by the INPI.
To specify that the designs are in 2 families, and therefore protectable by 2 ways.

. What is the right of prior invention?

It is an exception to the patent monopoly. According to the Article L. 613-7 of the Code of intellectual property, this exception recognize that "Any person who, within the territory in which this Book applies, at the filing date or priority date of a patent was, in good faith, in possession of the invention which is the subject matter of the patent shall enjoy a personal right to work that invention despite the existence of the patent"

The effect is: paralysis of the infringement action brought by the depositor or his entitled person.

However, this exception to the patent monopoly is subject to conditions :

  • The person claiming the right must have real possession of the invention;
    In other words, this person must have knowledge of technical invention and must know all the elements constituting the patent.
    Nevertheless, the exception requires only the simple intellectual control of the invention (enough complete and finished to be able to be implemented, without requiring inevitably an effective exploitation.
  • The possession and invention must be identical or similar ;
  • The possession must be prior to the date of the patent application or the priority date ;
  • The possession must be carried out on French territory ;
  • Possession must be "personal", it means it shouldn’t result to divulgation of the depositor before the filing date ;
  • Finally, the person must be in good faith, that means that the possessor is sincere when he made himself the invention or when he has legitimately received its author.
This is to the person who alleges the right of prior personal possession to prove it. MaPreuve enables you to get this evidence of possession.

Therefore MaPreuve recommends to deposit your researches, trials, tests, etc. made in France with www.mapreuve.com.
MaPreuve is a decisive advantage.

. What is the legal value of your proofs ?

Our protection is notably based on the legal system of the standardized electronic signature.

Since Directive 1999/93 /CE of the European Parliament and of the Council of 13 December 1999, implemented by the Act of 13 March 2000 on electronic signature, there is a new mode of proof: the normalized electronic signature. Only Trusted Third Parties may, within the meaning of these texts, give the electronic signature a legal value, admitted as proof in court.

The company Dhimyotis, creator of the MaPreuve website, has the qualification of Trusted Third Party thanks to obtaining national and European standards in this area.

Our time stamping service is synchronized on time servers, based on several atomic clocks. It is compliant with RFC 3161 standard.

It is important to note that our service is also in compliance with the eIDAS regulation coming into force in July, 2016.

The European regulation n° 910/2014 of July 23rd, 2014 about " the electronic identification and the reliable services ", applicable from July, 2016, has for objective to create a single market of the safety of the exchanges on the internet.

. Why legally protect myself ?

En droit d’auteur, selon l'article L. 111-1 du code de propriété intellectuelle, "l'auteur d'une œuvre de l'esprit jouit sur cette oeuvre, du seul fait de sa création, d'un droit de propriété...". Ainsi, vos droits s'acquièrent du fait même de votre création. Aucune formalité légale n'est demandée.

However, informality does not preclude the need to build up an evidence of prior art.

In case of dispute, the evidence of your creations is essential.

This is why our proof will allow you a defense before any jurisdiction in case of questioning of your quality of author. Finally, concerning the law of the industrial property, requiring a legal deposit (patent, mark, drawings and models), MaPreuve allows you to establish a proof before making this deposit, in particular on the different versions which precedes the final version which will be filed.

. What is the advantage in protecting myself as soon as possible ?

In terms of copyright, it is decisive to be able to establish his authorship and the date of your creation. Before any diffusion, we recommend you to constitute the proof of the existence and the date of your creation.

. What is the scope of proofs in court ?

MaPreuve offers proof with a certified electronic signature within the meaning of Directive 1999/93 / EC of the European Parliament and of the Council, transposed by Law n ° 2000-230 of March 2000 and Decree n ° 2001-272 of March 30, 2001 As a result, all our evidence has a presumption of reliability (Article 1367 of the Civil Code) and our writing in electronic form has the same probative force as the written form (Article 1366 of the Civil Code).

That which was reaffirmed by a recent ruling by the Supreme Court dated 30 September 2010 (No. 09-68555), stating that for an electronic signature to be valid it must consist of "the use of a reliable method of identification that ensures its link with the act to which it is attached. The reliability of this process is presumed until proven otherwise. "

In case of dispute, you can submit our evidence to the judge.

It should also be noted that the July 2014 European eIDAS Regulation provides for mutual recognition of qualified electronic signatures between the Member States of the European Union. Article 25 provides that "The legal effect and the admissibility of an electronic signature as evidence in court may not be refused on the sole ground that the signature is in an electronic form or does not meet the requirements of the qualified electronic signature ".

Our Evidence may be submitted to any European judge.

. How many countries are concerned by the protection of literary and artistic works ?
