ABSTRACT:
Network users are authorized individual access during a log-on session to encrypted content on content media at the user without the necessity of individualizing the content media for the particular user. The content may comprise multimedia data. The content media, which may be mass produced and distributed, includes a computer program which generates a unique configuration identifier upon instantiation of the program to begin a user access session. The program creates a virtual directory structure for the content that is uniquely determined for that session by the configuration identifier. The configuration identifier is uploaded to a remote server which uses the configuration identifier with other information identifying the content media and the user authorize user access. The remote server creates and downloads to a browser of the user an encrypted message containing URLs for accessing the content in the virtual directory structure and containing transformations of a decryption algorithm and decryption keys for the encrypted content. Encrypted multimedia content selected by the user is stored in a temporary file, decrypted in a moving time window, and rendered After rendering, the decrypted portion of the temporary file is scrambled to preclude further access.
