- Each block of data is encrypted using its own self-generated convergent key. These keys are themselves encrypted by a self-generated master key that only each user knows,
- The client device minimizes bandwidth utilization by determining whether the encrypted data blocks to transfer are already present in the cloud,
- The client device informs the cloud drive which data is likely to be required in the future so it can be made available with less latency if the client device requests the data.
BITCASA ISSUED U.S. PATENT FOR MORE EFFICIENT ENCRYPTION METHOD
The United States Patent and Trademark Office (USPTO) has issued U.S. Patent 9253166, which combines Bitcasa’s industry-leading security model with more efficient bandwidth utilization using deduplication and smart caching techniques. The patent describes Bitcasa’s process of simultaneous, convergent encryption and deduplication, combined with smart caching, which is accomplished using three methods:
Deduplication allows Bitcasa to benefit from the operational efficiencies resulting from the exclusion of redundant data. Cost-savings are passed on to partners, while users benefit from zero-knowledge encryption and a better user experience.
