Abstract
Systems and methods are provided for encrypting electronic files during a transfer to a low-security storage location is provided. In one embodiment, a method comprises receiving a file copy request for a file stored on a source storage system to be copied to a destination storage system; determining a desired file security level of the file based on a desired security level for the file when the file is accessed; determining a destination security level of the destination storage system; comparing the file security level and the destination security level; encrypting the file to create an encrypted file when the destination security level is less than the file security level prior to copying the file; and copying at least one of the file and the encrypted file to the destination storage system as a function of the comparison of the file security level and the destination security level.
