Current popular cloud storage services, including but not limited to, Dropbox, Amazon S3, Google Documents, Microsoft Azure, unfortunately do not provide the user with sufficient security guarantees. On the contrary, they explicitly decline any responsibility for lost or corrupted data in their service agreements.
Using our techniques, both users and companies will benefit. Users will enjoy increased security and provable cryptographic guarantees, while companies can charge premium fees for offering such guarantees, or can now have more customers who were worried about security issues.
We are grateful for the support from Koç Sistem, Türk Telekom, TÜBİTAK, and European Union COST Action IC1206.
