Method and system for restricted biometric access to content of packaged media

A method for restricting access to playable digital content on a network, comprising the steps of:

• uploading a playlist created by a user to a server, wherein the playlist is a data structure containing links to a plurality of digital content files,
• measuring biometric information of the user with a biometric component integrated with a portable music player;
• generating an authentication signal at the portable music player if a coincidence exists between reference fingerprint data of a fingerprint stored at the portable music player and measured fingerprint data of a fingerprint measured by the biometric component of the portable music player,
• with the portable music player, transmitting the authentication signal across the network to the server to authenticate the user of the portable music player with the server so that the successful transmission of the authentication signal to the server permits the portable music player to access (a) the previously uploaded playlist associated with the user, the playlist identifying playable digital content accessible to more than one user, and (b) protected playable digital content;
• and
• playing the protected playable digital content received over the network on the portable music player.

A portable music player to restrict access to digital content on a communications network, comprising:

• a portable music player to play for a user of the portable music player digital content received over the network;
• and
• a biometric measuring component, integrated with the portable music player, the biometric measuring component to measure biometric information of the user,
• wherein the portable music player is configured to generate an authentication signal at the portable music player if a coincidence exists between reference fingerprint data of a fingerprint stored at the portable music player and measured fingerprint data of a fingerprint measured by the biometric component of the digital content playing device,
• wherein the portable music player is configured to transmit the authentication signal across a network to a server to authenticate the user of the portable music player with the server so that the successful transmission of the authentication signal to the server permits the portable music player to access (a) a previously uploaded playlist associated with the user, the playlist identifying playable digital content accessible to more than one user, and (b) protected playable digital content,
• wherein the playlist is a data structure containing links to a plurality of digital content files, and
• wherein the portable music player is further configured to transmit through the network the playable digital content that is accessed upon successful receipt of an authentication signal at the server.
