How it works: - SENDING FILES Skizzle “talks” to your Gmail and inserts a security switch in your Compose window, once turned on, it edits your standard Attach action which encrypts files you choose, in the browser, and uploads the encrypted file to our distributed storage servers. The encryption keys to these files are stored, locally, in the extension and we or any other service do not have access to them, and hence they cannot be snooped on or exposed even if we are hacked. Your public-private keys are decentralized through over 100 servers, from which only the user can retrieve their keys. You send these files by hitting the Send button, which “shares” the file(s) with your intended recipients and stores these logs on a public blockchain(Ethereum). This enables public verifiability of who has access to which files at any point in time, in a privacy-preserving manner. - RECEIVING FILES The only time Skizzle reads your emails is when it encounters one with Skizzle encrypted attachments in them. Even when doing so, we completely ignore all of your email’s content. The extension only checks if there are any encrypted attachments and fetches them. When you hit the download button, your access permissions are checked and the encrypted file is downloaded and then decrypted locally with your keys, ensuring End to End Encryption. - REVOKING ACCESS Skizzle allows users to remotely revoke access to files shared. This means that the intended recipient, whose access has been revoked, can no longer download the file. The true power of this will be in effect when we release our “View Only” permission very soon. Users can set this permission on files they share so recipients cannot download these files(and then re-share with others) and revoking access remotely ensures no further access is possible. We would appreciate any feedback or features that you’d like to see in Skizzle. Contact us on hello@skizzlehq.com or https://twitter.com/skizzlehq Our Story: We built a decentralized privacy-centric data store at https://newfang.io. Think of it as AWS S3 with a focus on security and privacy. When looking at applications for our storage platforms, it became clear that sharing files over email or even via various cloud sharing tools was a major security/privacy sink. With Skizzle, we want to completely fix this and ensure that your data(files+information), whether in a personal or professional context, can remain private and completely in your control. As it should be.
