Abstract
A system for securely distributing content is provided. A distribution system includes a content server that distributes content to content clients via a communications link or a tangible medium. The distribution system uses passwords to encrypt and decrypt content and to control access to sensitive information stored on the content clients. The distribution system initially receives various passwords from a user and encrypts each password. Some of the encrypted passwords are “identification passwords” and others are “encryption passwords.” The identification passwords are used to control access to sensitive information stored on the content clients, and the encryption passwords are used to encrypt and decrypt content that is distributed to the content clients. The distribution system configures each content client to contain the identification passwords and encryption passwords in a secure folder.
