The security of data sharing is guaranteed by end-to-end encryption,as files are encrypted immediately by the browser (via ElGamal 2048 and AES 256 encryption).

Our solution includes a unique technology:
the integration of a digital escrow with quorum (patent Inria / CNRS) allows to control and recover the exchanges in compliance with the GDPR thanks to the validation of a quorum of people.

Thanks to a strict split between the request, the validation, the access to the recovery; the administrators of the quorum never have access to the data.
Only the co-workers who have the decryption keys can decrypt the files

Unique AES key for each file deposit-> encrypted by the public keys of those with access

Use case

You’re in charge of

an industrial property firm…

For you, protecting the exchanges of data with organizations applying for patents is critical. Data are confidential, disclosure has a potentially significant financial impact for the firm and your client and, in some cases, attackers may have the resources or be a nation-state.

At the same time, the heterogeneity of clients’ computers is very important Windows XP, 7, 8, 8.1, 10, MacOSX, Linux, Microsoft Edge, Firefox, Chrome, Safari are some of the items you can find. It is very complex for interlocutors to install specific software on their position due to centralized management of computer stations.

Finally, the organization must be able to control data, exchanges and have a high level of traceability of exchanges.

CryptnDrive meets all these requirements: there is no software installation for the interlocutors since it is only necessary to use a web browser; the encryption of information (AES 256 and ElGamal 2048) offers very high protection of information, finally the solution is manageable internally for organizations in order to have a complete control
