Abstract
Embodiments of the present invention are directed to a system capable of enforcing document security and delivery policies. In particular, the present invention allows for the detection and removal of files attached to electronic messages. When an attached file is removed from an electronic message, the file may be placed in secure storage. A link to the stored file is inserted in the electronic communication prior to delivery of the message to the addressee of the communication. In order to access the stored file, the recipient of the message is required to select the provided link, which establishes a secure communication channel between the secure storage device and the receiving client computer. Optionally, the recipient may also be required to provide a password and/or digital certificate in order to access the stored file.
