The individual fragments are stored encrypted on at least three highly secure ISO-27001 certified servers in Germany. This ensures that the files are never visible or misused by third parties, as only encrypted fragments of the files are available. Only when they reach the right user, the fragments are reassembled and decrypted and thus become fully-fledged files again. The CloudRAID technology was developed together with the Hasso-Plattner-Institute.
This encryption key always stays on the user’s device. With this key only, the files of the user can be decrypted again to ensure that only authorised users have access. No third-party or admin can read the data. This encryption system was developed the Fraunhofer AISEC research institute according to BSI-guidelines.
The latest cryptographic algorithms are used to encrypt the files on the users' devices. The key always remains on the user's computer. Additionally, the encrypted files are split into blocks and distributed to at least three cloud storage services.
Bdrive protects your company data from unauthorized access. Even Bdrive-developers or Cloud storage providers don’t have access to the files shared in Bdrive due to the zero knowledge.
Through the possible adjustment or revocation of access rights, the owners always have full control over your data. In any case, Bdrive logs every change or editing made.
