Hello technion, thank you for your feedback! At this time the website just presents the main ideas and you can only sign up to the newsletter. Regarding the tech behind our idea compared to the competitors, current solutions utilize Order (or property) Preserving Encryption or offer semantic security. This means that everything is encrypted once and uploaded to the cloud. Then, local indices help you retrieve the correct encrypted data. These approaches reveal the pattern of accesses (the frequency each encrypted file is accessed, if some encrypted files are accessed always together, and how many encrypted files are returned each time). It is proven that this information is enough for the cloud provider or anyone listening to the communication channel to infer the exact index information. The more attributes are indexed, the more information about your files/database rows is inferred and potentially, an adversary can reconstruct all your data without even breaking the encryption. There are strong cryptographic techniques solving this problem by essentially re-encrypting some of the files each time you retrieve data (e.g., ORAM), but they were deemed non practical. F-Lock uses the latest advances in the field of ORAM and Differential Privacy in order to overcome any potential attacks, while retaining the practicality of the solution. Sorry for the long reply! We hope this information is helpful. The F-Lock team
