First Claim
1. A method for providing a portable secure interface to a data storage cartridge, said data storage cartridge having data storage media for storing data for read/write access by a user of a data storage drive when mounted in said data storage drive, and a wireless interface mounted in said portable data storage cartridge for receiving power and data from, and sending data to, said data storage drive when mounted in said data storage drive, said data storage cartridge having a user table separate from said data storage media, comprising at least a unique user identifier for each authorized user and at least one permitted activity said user is authorized to conduct with respect to said data storage media, said user identifier, when combined with a user authentication message from said authorized user in accordance with a predetermined algorithm, authorizes said user, said method comprising the steps of:
- receiving said user authentication messages from said data storage drive via said wireless interface;

Abstract
A portable security system mounted in a portable data storage cartridge for managing access by users to the cartridge. A programmable computer processor mounted in the cartridge is powered by and transfers data to a data storage drive via a wireless RF interface, when mounted in the drive. A user table has a unique user identifier for each authorized user and lists permitted activities of the user for the cartridge. The user identifier comprises a user symbol and a user decrypting sender public key. An authentication message from the authorized user is encrypted by a sender private key and a receiver public key. The cartridge processor decrypts the message employing a receiver private key and the sender public key, whereby the user authentication message is known to have come from the user and grants access to the user for the listed activities for the cartridge.
