Abstract: A data set shared by multiple nodes is encrypted. The data set can be split into independent records. The records can be encrypted and shared independently, without the need to modify and transmit the full data set. Although the records are encrypted with their own encryption key, they are all accessible by a single authentication method.

Abstract: Systems and methods authenticate with application extensions. An application extension requests a token from a local application. The local application generates a token and either inserts the token into a protected storage accessible only by the application extension being run by the current user or returns the token back to the application extension after being confirmed by the legitimate user. The application extension uses the token to authenticate itself with the local application.
