    摘要: A system, method apparatus, and computer readable medium for managing renewal of a dynamic set of data items. Each data item has an associated renewal deadline, in a data item management system. A renewal schedule allocates to each data item a renewal interval for renewal of the data item. On addition of a new data item, if a potential renewal interval having a duration required for renewal of the data item, and having an ending at the renewal deadline for that item does not overlap a time period in the schedule during which the system is busy, the renewal schedule is automatically updated by allocating the potential renewal interval to the new data item. If the potential renewal interval does overlap a busy period, the renewal schedule is automatically updated by selecting an earlier renewal interval for at least one data item in the set.

    摘要: Scheme for switching a computer system (21), which is connectable via a communication interface and a network (22) to a server module (23), into a special mode of operation. The computer system (21) comprises a software component (26) for sending an identifier (w) assigned to the computer system (21) via the communication interface and the network (22) to the server module (23). In response, the software component (26) receives a token (S), issued by the server module (23), whereby the token (S) comprises a credit (C). In addition, the computer system (21) comprises a trusted hardware component (25) storing the identifier (w) and comprising a credit counter (44) with a credit which is automatically exhaustible step-by-step, and which is updateable with the credit (C) received from the server module (23). The computer system (21) has a trigger unit for switching the computer system (21) into the special mode of operation, e.g. a mode where the computer system (21) is of limited use to a user, if the credit of the credit counter is exhausted.

    摘要: A network-attachable computer system (40) that comprises a network interface for connection to a network (41), a server module address, a secure identifier (ID), and a key k. The computer system (40) generates identity information which comprises the secure identifier ID and which is protected using said key k. This identity information is automatically sent via the network interface to a server module (42) which is reachable via the network (41) by using said server module address where it is used to determine whether the respective computer system (40) is reported lost or stolen.

    摘要: A mechanism is provided for controlling a solid state storage device in which the solid state storage comprises erasable blocks each comprising a plurality of data write locations. Input data is stored in successive groups of data write locations, each group comprising write locations in a set of erasable blocks in each of a plurality of logical subdivisions of the solid state storage. The input data is error correction encoded such that each group contains an error correction code for the input data in that group. Metadata, indicating the location of input data in the solid state storage, is maintained in memory. An indication of validity of data stored in each data write location is also maintained. Prior to erasing a block, valid input data is recovered from the group containing write locations in that block. The recovered data is then re-stored as new input data.
