Abstract
Systems and methods for privacy-preserving data loss detection include performing a sweep of online information for a candidate data leakage to generate an online data set; performing an analysis of the online data set to determine that the online information is a candidate data leakage; the host encrypting the data communication and providing the host-encrypted data communication to a software agent at the enterprise; in response to receiving the host-encrypted data communication, the software agent encrypting a database of enterprise information and re-encrypting the host-encrypted data communication, and providing the same to the host; the host decrypting a host-encrypted aspect of the re-encrypted data communication to generate a software agent-encrypted data communication; determining whether a match exists between the encrypted database of information and the software agent-encrypted data communication; and based on whether the match exists, the software agent taking a first action or the host taking a second action.
