Abstract: A method for controlling access to a storage unit owned by an owner, wherein a renter can obtain and maintain rights to said storage unit by paying a first rental fee and subsequent periodic rental fee payments according to a schedule. In this method, the storage unit is secured by a lock that is, at least in part, controlled by the renter. A remotely controllable lockout assembly, however, is capable of over locking the storage unit so that the renter can no longer gain entry when the lockout assembly is activated. The method includes remotely controlling the lockout assembly to deny the renter access to the unit when the when said renter has failed to pay said periodic rental fee on schedule and a grace period has passed since said renter's rights to said storage unit have elapsed.

Abstract: A tape system is provided with an encryption capable tape drive and an encryption enabled tape drive device driver for the encryption capable tape drive. The encryption enabled tape drive device driver functions as a proxy which connects the encryption capable tape drive to a key manager which serves keys to the tape drive. When the encryption capable device driver causes a command to be sent to the drive, the tape drive is configured to respond with a message that is intended for a key manager such as an External Key Manager (EKM). The encryption capable device driver recognizes that this is a message intended for the EKM and forwards that message to the EKM (e.g., via an Internet Protocol (IP) connection). The EKM then responds to the key request by issuing a new key (for a new cartridge which is to be written from beginning of tape (BOT)) or an existing key (for a cartridge which needs to be read).
