Abstract

Systems and methods for securing or encrypting data or other information arising from a user'"'"'s interaction with software and/or hardware, resulting in transformation of original data into ciphertext. Generally, the ciphertext is generated using context-based keys that depend on the environment in which the original data originated and/or was accessed. The ciphertext can be stored in a user'"'"'s storage device or in an enterprise database (e.g., at-rest encryption) or shared with other users (e.g., cryptographic communication). The system generally allows for secure federation across organizations, including mechanisms to ensure that the system itself and any other actor with pervasive access to the network cannot compromise the confidentially of the protected data.
