Data access and contracts

The enrolment session is an information session organized in CASD offices, as a high level of security is needed. At the end a signature of your fingerprint will be recorded on a smart card which you will be given. Without it you cannot access data.

Yes, if the documentation was provided by the data producer.

In this case, the stat team will ask the data producer. You will be kept informed.

You can send us your files (programs, tables …) by email (, using XChangefile, which handle heavy files well, or by coming to see us (USB key, CD-Rom…).

Important: for security reasons, we must check what comes and goes at CASD. We thus require a description of the files. By default files are put in the “common” project server space.

When you wish to retrieve files (results, programs…), you will be brought to generate a “CASD output”, as you cannot carry out your file from the closed environment.

Here is the following procedure:
• Insert in a specific folder the files you wish to export;
• Create an archive (.zip) with this folder ;
• Click right on the .zip file and select « Sortie CASD » ;
• Write down the 16 char key ;
• Click on « Valider » to finish.

Then send us an email ( using the name of the project and the 16 char key in the object of the email.

Important: You must describe the content of your output in a text file to be included in your zip folder, so that the CASD statistics team can verify that the content is compliant with confidentiality rules.

From the onset of your project you have 20 outputs which you have three years to use. Mort outputs can be ordered. The price for an output reflects 30 minutes of verification by CASD staff. So an export can amount to more than a unit (if it requires more than 30 minutes to check) or less (if it requires less than 30 minutes).

Your request for an output will be addressed only if you have sufficient output credits. Otherwise we will ask you to order a credit package

Example: If your first output request requires 10 minutes to be treated by the CASD statistics team then a second request requires 35 minutes, the total will amount to 1,5 outputs.

If you have the subsidized prices (see price list), you have to quote CASD, using precisely these terms:
• « This work is supported by a public grant overseen by the French National Research Agency (ANR) as part of the “Investissements d’Avenir” program (reference: ANR-10-EQPX-17 – Centre d’accès sécurisé aux données – CASD)”

The subscription linked to a project, meaning users and related services, can only be funded by one and only one legal entity. However an SD-box can be funded by a different legal entity, and several boxes may be funded by different legal entities.

No, only legal entities can pay.

No, only in the premises of a legal entity.

Yes, by simply using the smart card.

12 months minimum. After that period, 6 months minimum.

The starting and closing dates (= billing period) are those written on the quotation which has been signed. They are agreed upon with the project leader and reflect the project needs.

Users can access data only once all these steps have been completed:
– authorizations delivered by relevant authorities
– contracts and quotation are signed
–At least one user has been enrolled
– sending an SD-Box (if relevant)

The first subscription starting date is the “anniversary date” upon which a subscription must be renewed. Contracts may be discontinued at that date.

Such accesses are subsidized. When a project has but one student, doctoral or postdoctoral, 444 EUR is discounted on the total yearly subscription price. If one or more, then a 50 % discount is granted on the latter accesses (in top down order on the pricelist). This rebate is granted only upon proof (student card for example).

Configuration, output packs, additional users, Additional SD-Box. For all these it is possible, just email us at:
