Find answers here to the most frequently asked questions about certification, prior existence, integrity and storage of your files.
Rightkeeper is a digital proof solution that lets you document the existence of a file at a given date, verify its integrity and preserve the associated evidence.
With each deposit, Rightkeeper generates a digital fingerprint of the file, links it to a time reference and anchors the evidence on a public blockchain. A certificate summarises the deposit information.
It works in four steps:
Deposit: you deposit your file in Rightkeeper.
Calculate the fingerprint: a unique digital fingerprint is calculated from the file’s content.
Time-stamp and anchor: the fingerprint is linked to a time reference and the evidence is anchored on a public blockchain.
Certify: a proof certificate summarising the deposit information is made available to you.
You can then find your proof, download its certificate and, depending on the features available, share the file or add it to a proof folder.
A digital fingerprint is a string of characters calculated from a file’s content using a cryptographic algorithm. Rightkeeper uses the SHA3-256 algorithm to generate this fingerprint.
Even the slightest change to the file produces a different fingerprint. This fingerprint therefore lets you verify that a file exactly matches the one deposited, without writing the file itself to the blockchain.
It is one of the essential technical elements of the digital proof established by Rightkeeper.
When a file is deposited, Rightkeeper records the deposit date and calculates its digital fingerprint. This fingerprint is then anchored on a public blockchain as part of the proof-building process.
Two dates are therefore distinguished: the date of deposit in Rightkeeper and the date of the blockchain transaction. Once the transaction hash is received, the status changes to “Proof created”.
These two dates document different stages of the proof process.
Rightkeeper uses a public blockchain to anchor cryptographic references associated with deposited files. This anchoring makes it possible to find a transaction and verify the information recorded in it.
The content of the transaction depends on the plan: for a paid plan, it contains the file’s fingerprint; for the free plan, it contains a hash derived from a batch of file fingerprints. The original file is not written into the transaction.
The proof is considered created when Rightkeeper receives the transaction hash from the public blockchain used. The corresponding status in the app is then “Proof created”.
The deposit date is when the file is recorded in Rightkeeper. The certification date shown on the certificate corresponds to the blockchain transaction step, according to how the service works.
These dates may differ, because the transaction needs to be processed before its reference is received by Rightkeeper.
The proof certificate is a document that summarises the information relating to a file’s deposit, including its digital fingerprint and the time and technical references associated with the proof.
It lets you keep and present the information from the deposit. It is a certificate of deposit and proof, not a certificate that automatically attests ownership of a creation or title to rights.
These three elements play different roles:
The file is the original document you want to document.
The digital fingerprint is the cryptographic reference calculated from its content.
Together, they let you find the document and verify that it matches the recorded fingerprint.
The proof certificate summarises the information relating to the deposit and the proof created.
Rightkeeper is designed to document many types of digital files: documents, images, graphic designs, videos, design files, texts or AI-related content.
Accepted formats and size limits depend on the service’s technical conditions.
Rightkeeper is for professionals and organisations that need to document the existence and evolution of their digital files.
It can be used by companies, research and development teams, lawyers and intellectual property professionals, agencies, studios, freelancers and creators.
The certificate includes a verification reference and a link to view the proof online. It also includes a reference to a transaction on the public blockchain.
This information lets you find the references associated with the deposit and carry out the verifications provided by the service.
From your Rightkeeper dashboard, drag and drop the file you want to protect or select it with the “+ Deposit a file” button. Follow the steps shown in the app to start the deposit.
Rightkeeper calculates the file’s digital fingerprint and starts the proof-building process. When the status shows “Proof created”, you can access the information associated with your deposit.
Check the status of your deposit in the app.
While the process is under way, the proof has not yet been created. When the status changes to “Proof created”, the process is complete and the proof certificate is available.
Find your files in the My deposits section of your Rightkeeper account. There you can view your deposits and access the information associated with each file.
From your deposit in Rightkeeper, click the “Certificate” button. The certificate opens in a pop-up window. Click the download button to save it as a PDF on your device.
Yes. The deposited file remains available for download from the “Deposits” section by clicking the file name, under the service’s retention terms. You can therefore retrieve the document and its certificate, even if you have lost a copy saved elsewhere.
If your file has changed, deposit its new version on Rightkeeper. It will be a new deposit with a new digital fingerprint.
The initial proof remains associated with the version deposited previously. Both deposits document different stages in the file’s evolution.
Select the relevant files from your deposits, then use the proof folder feature available in the app.
You can then group the relevant items in a single folder. The exact validation and sharing options depend on the features available in your version of Rightkeeper.
You can create a share in two ways:
From “Deposits”: select one or more files, then choose the share action.
From “Shares”: create a new share and add the files you want to send.
You can group several files in the same share to make sending them to your recipients easier.
Yes. You can delete a file at any time from the “Deposits” section. The file and its certificate are then deleted from Rightkeeper: download them first, as we will no longer be able to provide them afterwards. The fingerprint written to the blockchain cannot be deleted: it remains permanently recorded, with no link to your account. With a paid plan, the proof can also be verified without Rightkeeper.
With the free plan, verification is only possible through Rightkeeper, using the URL shown on the certificate issued.
Open the proof folder you want to send and use the corresponding share feature.
The recipient can then access the items in the folder, according to the share’s permissions and settings. This makes it easier to send several items together rather than separately.
The Rightkeeper certificate documents the deposit of a file and the technical elements associated with its proof, including its digital fingerprint and the corresponding time and transaction references.
It lets you verify whether a file matches the fingerprint associated with the deposit. It is evidence that can be presented in a legal context, but it does not on its own guarantee the outcome of a dispute.
No. The certificate documents the information associated with a file’s deposit, but on its own it cannot identify the author with certainty or show who holds the intellectual property rights.
It can, however, help document the existence of a file at a given date and be used alongside other evidence to support action to protect your rights.
Evidence created with Rightkeeper can help document the existence and integrity of a file at a given date.
Its legal weight depends on the context, the circumstances, the other evidence presented and the assessment of the competent authority. Rightkeeper does not guarantee that a proof will be deemed sufficient in every situation.
Rightkeeper and the e-Soleau envelope are two separate mechanisms for documenting the prior existence of a creation.
They rely on different mechanisms and do not necessarily produce the same effects. The choice between them depends on the nature of the project and your protection needs. Rightkeeper is not legally equivalent to the e-Soleau envelope.
No. Depositing a file on Rightkeeper does not automatically create copyright and does not guarantee recognition of your authorship.
Rightkeeper lets you build and preserve evidence associated with your files. This evidence can help document a creation, its evolution or its existence at a given date, alongside other evidence useful for defending your rights.
Yes, evidence from Rightkeeper can be presented in a dispute, depending on the nature of the case and the applicable rules.
Its admissibility and probative value are assessed in light of the context and other available evidence. In the event of a dispute, we recommend consulting a lawyer or intellectual property professional.
No. Rightkeeper is a technical tool for building, preserving and organising digital evidence.
On its own, it does not provide legal advice and does not replace the support of a lawyer or intellectual property professional to define a protection strategy, analyse a dispute or defend rights.
A prompt can be an important step in a creative or professional process. Depositing it on Rightkeeper documents its content at a given date and preserves the associated evidence.
This can be useful to follow how work evolves, keep a record of its different stages or document a creative process that uses artificial intelligence.
Rightkeeper lets you build evidence associated with the file containing a prompt. This can help document its existence and content at a given date.
However, the deposit does not automatically grant an exclusive right over the prompt. Its legal protection depends on its nature, its originality and the applicable context.
Yes. You can deposit a file containing a creation generated by artificial intelligence, subject to the formats and technical limits accepted by Rightkeeper.
The deposit documents the file’s existence and preserves the associated evidence. On its own, it does not determine whether the creation is protected by copyright or who holds any rights.
Yes. You can deposit the different versions of a prompt or AI-generated file to build separate proofs at different stages of the process.
Each new deposit documents a new version at a given date. This can help trace how your work has evolved.
Rightkeeper documents a file’s content and its existence at a given date. On its own, it cannot show that you are the sole author of an AI-generated creation.
To document a creative process, you can keep several elements: prompts, different versions, intermediate files and results. These can be deposited separately to build a history of your work.

Custom: for teams and organisations that need to manage several users and share proof folders.
Yes. Secure sharing is included in the Free, Pro and Custom plans.
However, share tracking is included in the Pro and Custom plans, but not in the Free plan.
No. Proof folders are included in the Pro and Custom plans. They are not included in the Free plan.
For teams and organisations with specific needs, the Custom plan is available on quotation. You can contact a Rightkeeper expert to discuss your file volumes, number of users and access management needs.
Rightkeeper relies on a hosting infrastructure located in France and Europe. Detailed information about hosting and data processing is provided in the service’s security and privacy documentation.
Access to files depends on the service terms and the permissions granted. When you share a file, you allow your recipients to access it according to the share settings.
We recommend sharing your files only with the people concerned.
No. The original file is not written into the blockchain transaction.
For the Pro plan, the transaction contains the file’s digital fingerprint. For the free plan, it contains a hash derived from a batch of file fingerprints. In both cases, the file’s content itself is not published on the blockchain.
At deposit, Rightkeeper calculates a digital fingerprint of the file using the SHA3-256 algorithm. This fingerprint is linked to the deposit’s evidence and anchored on a public blockchain according to the mechanism used by your plan.
If the file is modified, its fingerprint changes. Comparing it with the recorded fingerprint shows whether the file matches the one deposited.
Yes. The deposited file and its proof certificate remain available for download from your Rightkeeper account, in accordance with the service terms.
You can therefore retrieve a copy of the file and the associated evidence, even if you have lost a copy saved elsewhere.
Yes. You can delete a file at any time from the “Deposits” section. The file and its certificate are then deleted from Rightkeeper and the associated metadata is anonymised: download them first, as we will no longer be able to provide them afterwards.
Deleting a file does not erase the proof itself: the fingerprint written to the blockchain remains permanently recorded, with no link to your account.
Rightkeeper anchors evidence on a recognised public blockchain. The availability and verification options of a transaction depend on how that blockchain operates.
