Abstract
Systems and methods for data loss prevention while preserving privacy are described, including receiving a data communication originating from an online account of a user device associated with the enterprise; performing an analysis to determine that the data communication is a candidate data leakage, based on a context of the data communication; encrypting the data communication, and providing the host-encrypted data communication to a software agent at the enterprise; receiving a software agent-encrypted database of enterprise communication and the host-encrypted data communication, re-encrypted by the software agent; decrypting a host-encrypted aspect of the re-encrypted data communication to generate a software agent-encrypted data communication; performing a matching operation to determine whether a match exists between the encrypted database of information and the software agent-encrypted data communication; if the match exists, reporting the match to the software agent; and if the match does not exist, the host taking an action.
