Abstract
A client computer system receives a file that is at least partially encrypted. The client computer also receives a file manager and user input. In response to the user input matching data stored in an encrypted user profile, the client computer uses the file manager to decrypt the file based on a key stored in the encrypted user profile. The file is unusable if copied to another client computer, and the file manager manages usage of the file based on one or more terms of usage.
