Abstract: Disclosed are a system and method for identifying and protecting sensitive data contained in a network client's file comprising obtaining a plurality of available digital fingerprint categories from a fingerprint-evaluating server, generating said file's digital fingerprint using said plurality of said digital fingerprint categories obtained from said server, transmitting said file's digital fingerprint to said server, comparing said digital fingerprint to a plurality of digital fingerprints stored in a database, detecting whether a match between said generated digital fingerprint and at least one of said plurality of said digital fingerprints stored in said database is found, and designating said file as containing or not containing sensitive data according to established data protection policies.

Abstract: The invention provides a system and method for writing data to a removable media device in accordance with a security policy. According to a method of the invention a request to write data to a first file on the removable media device is detected. Dummy data is written to the first file instead of writing the requested data. The requested data is written instead to a corresponding second file on a fixed media device. The corresponding second file is compared to a security policy. Response to the write request is based on the results of the comparison.
