It's evidently hoping improved efficiencies in its back end infrastructure, plus a continued commitment to "zero knowledge encryption" (client-side encryption) will help it hold on to most of its customers and continue to attract new ones.
"If you offer zero knowledge encryption we understand the motivation for that, but there are downsides to it," he said, citing services like search, access to third-party apps, seamless access to data from mobile devices and other features that would be impeded if people put more encryption into Dropbox.
Operating in the enterprise cloud storage and collaboration market, Tresorit provides what it describes as zero-knowledge encryption technology and unique encryption key management.
The API functionality includes a number of features, including file management, file sharing, media transcoding, and zero-knowledge encryption, all on public cloud storage.
End to end encryption and (nearly) zero knowledge systems exist to prevent this kind of hack in addition to the occasional National Security Letter.
That is obviously a shock, not in terms of our technical knowledge of encryption, but in terms of our political beliefs.
Tresorit's zero-knowledge e2e encryption architecture means that, unlike cloud storage giants like Dropbox, it cannot decrypt and access users' files.
In an Internet-connected world, that could again be the case, but not if encryption is used to keep knowledge from people.
Zero knowledge storage, end-to-end encryption, blockchain-based verification, publicly verified encryption methods — all tools any user has at their fingertips should they want them.
Homomorphic encryption [26] allows computations over encrypted data without decrypting them and without the knowledge of the secret keys.
