  • Data loss prevention using an ephemeral key
    Patent number: 8499359
    Abstract: A user requests to store a file to a storage device and a DLP module receives the request. The DLP module receives data for the file, encrypts the data using an encryption key and stores the encrypted data to the storage device. Next, the DLP module determines whether the encrypted data in the file is in compliance with a DLP policy. To determine compliance, the DLP module decrypts the data using the encryption key and examines the decrypted data for compliance. If the decrypted data is not in compliance with the DLP policy, the DLP module deletes the encrypted data from the storage device.
